Data for project: github.com/notDavidsGit/uhmmm...
Notes:
1. 2:16 The data set has 40 uhmmm lists, though a couple come from repeat individuals. This was to test if people uhmmmed consistently. This does appear to be the case but I didn't have enough people to conclusively say so, so I didn't mention it. Moreover, as I discuss later in the video, not all of the people are science educators - for example at least two are politicians, which was to test if training reduced uhmming.
2. 8:31 Surrogate analysis involves creating new data that follows a known distribution. This can be difficult in general, but in Poisson this is really easy - lets say the rate of your real data is 1 event in 10 time units, then you make a list of length say 10000, where 1000 of those are `1' and the rest are `0', and then you randomly permute that list and it will be Poisson. Next you compare the distance between the real data and the surrogate data. One common approach is using the Kolmogorov-Smirnov distance, which measures the maximum difference between the cumulative distribution functions. If the distance is small, it suggests that the real data follows the assumed distribution (e.g., Poisson), while a large distance indicates otherwise.
3. 11:56 This is related to the previous note. Here what I mean to say is that Matt and Tom's Kolmogorov-Smirnov distances are large, so they are not likely to be Poisson. Pretty much everyone bellow Matt and Tom have small KS distances and so they are statistically likely to be Poisson. This is true even if that person is not on the line, and suggests that if we took more data they would approach the line.

Excellent video! I've never been so honored to have a few "um"s pointed out.
@@0_- Liked your calculus videos helped me a lot
Wow! Didn't expect to see my favorite TH-camr comment on a video an hour before me, but here we are :)
I'd be fangirlling so hard rn if I was Not David
Wow hi
😅
I think the Q+A bit matches up with my personal theory (without any evidence) that Tom and I have long stretches with fewer uhms because we are flipping between bits of material we have presented to audiences loads of times, with new bits we are talking about for the first time. So I guess you can tell when a speaker is being spontaneous by counting uhms; and be offended if there are none and they are just wheeling out old material.
This is what I suspected but I didn't want to say it explicitly in fear of skewing opinions on the matter, but its nice to get some anecdotal confirmation. And thank you again for your "participation" in the "study"!
Now _this remark_ will definitely ruin my ability to watch live presentations 😆
Uhhhm
It's a learnable skill, though. There's a British radio show called “Just a Minute” where hesitation (among other arbitrary rules) is a rules violation, and some people are quite good. Or you could look at competitive debaters, who can (some of them, and if they want) talk indefinitely _impromptu_ without umming.
@@niiiiiiiiiiiia Its common for public speakers to take courses on getting rid of "umms" When I took public speaking courses in college our professor said "Pauses are just as good as "umms" and "likes" for collecting yourself before continuing, but no one notices them if they are only as long as your regular "umm". It will make you appear to be more familiar with the topic" Its an older tool. So, if you notice someone not using any "umms", try to pick out short pauses instead. Its the same linguistic hesitation just no vocalization to go with it.
Fun fact tangentially related to the topic:
‘Um’ Is a very much language specific mid-thought processing buffer. My parents, for reasons of their own, went to language school together as adults To learn Spanish. A point of advise they received from a teacher was that, knowing that you won’t be a native speaker quickly but you need to be passable enough communicate within a short period to later learn through persistent exposure, it was beneficial to pick up certain linguistic attitudes that essentially amount to little flags that point to - in this case - Spanish. One of those little modified behaviors was to replace ‘um’ and its friends with the Spanish appropriate ‘eh’ and crew.
The teacher went on to roughly explain the idea that by ‘um’ing in the language you are attempting to speak rather than English that people around you generally are more patient/willing to help. Psychologically you might say the person sees you less as a bumbling foreigner butchering the language and more of a student who is a bit above their head but dutifully trying their best.
that was an interesting story, thanks for sharing! Might have helped my french had I known that little tip...
yess i thought it so interesting that different languages have different "um"s, in Japanese i believe they say "eto" and "ano"?
If someone thinks a foreigner learning a second language is a bumbling idiot, they should piss off. Why take any effort to appease such people? Uhm however you want.
exactly the same in french! “um” will make them switch to english out of pity, but “euhh” will normally give them more patience.
@@kai_fatallysapphic this is largely the case because different languages have different systems of sounds and may land on a different "neutral" mouth position, neutral in the sense that it is a midpoint between all vowels. for Spanish, it happens to be 'eh' (/e/); for English, 'uh' (/ə/). this is a great clue for fluency (or passing fluency) because getting used to this position basically trains your brain to shift your entire vowel space to the target language.
This is a great example of why interdisciplinary interaction is so essential to science!
My dad's a speech pathologist, and as a kid I had a bad stutter. A lot of the problem was actually that I _didn't_ um. So when I'd reach a "bridge" between thoughts, where I needed to connect two ideas together (which might have different familiarity levels), instead of filling my lag time with filler words (um, er, ah, like, so, etc) my brain would grab onto my previous secure point--the last word I said--and repeat it until the connective pathway was established.
Like another comment mentioned, this is part of why the rate of 'um' is higher in those who speak quickly: We're covering more ground faster, so the brain has to take more beats to connect ideas. 'Um' becomes like every other words: We use more of them.
It's also why people who _think_ quickly--or slowly, too--say um more often. Thoughts grow out of sync with words, and we pause to realign things.
As you can probably guess, my 'why' phase lasted about 8 years, and my dad ended up explaining probably a quarter of his graduate program to me in that time. A fascinating blend of linguistics, physiology, psychology, physics, and more!
This was such a great read, thanks for sharing!
This makes so much more sense!
Interesting how UM helps collect your thoughts and focus, so similar to the mantra, OM.
Interesting...
now i feel like i should um more because my thoughts are consistently way faster than my mouth, and i try to speed up my speech rather than slow down my thoughts...
My instinctive explanation for why people like Tom Scott have lower averages and higher variations is that during their presentations they go into scripted bouts, a groove where they are explaining something and where the next sentence to say is obvious and comes quickly. And they are very skilled in executing these. But then, in between these sections, when transitioning between segments, or maybe if soemthing else broke their rythm, they revert back to a more natural average like normal people. thus the variation.
If that were the cause, would they still follow a poisson distribution? In switching between scripted and unscripted segments, they’d be essentially platooning their uhms, so if this is the case then the average should tend away from the poisson distribution and towards the platooned distribution.
@@JamUsagi Indeed, but that's already in the video. See @11:52
@@nickdumas2495 Ah yeah, the video bugged out on my first viewing so I must have missed that part, my bad
Pretty intuitive ❤
I also guess that one "um" may throw you off and you have to "um" a few more times to regain composure. I know ive done that lol. like when i loose track of what im saying it takes a few seconds to get back on track lol
Tom Scott 1000% adds ums and other similar pauses to his speeches on purpose. It's something I noticed a long time ago, and I think it's a *huge* part of why he's so successful at communicating technical information to such a general audience.
I don't know if it's on purpose, you'd have to ask him, sometimes people are just like that!
Wait, what? How would artificial uhms improve someones presentation? I mean, they're just meaningless noise so what's the point? I'd love to hear more about your idea
@@michaw7408 Tom is keen on trying to do videos in one take, if possible. So I think at the very least he doesn't see the occasional "uhm" as disruptive
When Tom goes "uhm", the audience knows he's going to get to the interesting bits. I think their use in language is to communicate "I am choosing my words, please pay attention". And for experienced speakers, they can prime listeners to pay attention. While inexperienced speakers are inconsistent with it, and might be grating/tiring the listeners attention.
@@michaw7408 nothing habitual is absolutely meaningless. Why would every human waste energy on something meaningless? You could argue the subjective value of the meaning but to assert 0 value is outright silly. (Well, perhaps you spoke absolutely in effort to incite a corrected response providing you with the answer, which isn't silly after all.)
Personally though, I get forced to "uhm" a lot more than I innately would during pauses. For example, my father is always seemingly caught off-guard when he hears a silent pause. He will interrupt what I'm about to say, just to question my unfinished thought. (Like, "if you'd just shut up and let me finish!..") If I don't fill that void with a predictable noise, then he will. A simple 'uhm' lets him know I'm still forming the sentence. Whether that's purely a condition of avoiding confusion, through losing some hearing as he ages, is harder to say. It happens with people of all ages though. I believe it's just nurtured/conditioned in your specific environment.
I'm also quite detailed and long-winded, so I get interrupted consistently the moment I hesitate, by nearly everyone I speak to.
I agree with other comments as well, 'uhms' can be scripted for emphasis, rhetoric, or other metacommunication.
In practice, language is rarely literal. People, and therefore language is far too emotional in daily use. Close enough to their intentions, is close enough for most.
@michaw7408 if the speaker is attempting to sound more casual, it would make sense to insert a few ums and uhs to make it sound natural and more like a regular conversation. I kind of doubt he would need to do that since going unscripted is likely going to lead to the same result with less effort, though. It would only be necessary for someone who is hyper aware of what they're saying and never ums normally
8:15 just realized this area is the end of a level for Super Mario Bros. and the busses are a reference to the "frame-rule" concept for which players will often use busses as an example to explain. Not what I expected here lol
That's one of the most amazingly obscure references I've ever seen
says more about how the brain works than any other information in the video
I was going to comment this exactly but I am glad I no longer have to type that out.
I love that detail, but I don't love typing.
@@redstonewarrior0152 yet you typed this comment. I guess less word count?
The busses are also labeled "Route 1-1" which is a reference to World 1-1.
The most interesting thing to me about uhm/erm/umm/etc. is that it's such a great example of the schwa.
The phonetic sound ə ("schwa") is the default sound that humans make. If you just open your mouth and pass air over your vocal chords, you say "ə".
Because of that it's the most common sound in almost every language. Three of the four most common English words are "the" ("ðə"), "of" ("əv"), and "a" (just "ə"). The first words of most babies are "məmə"/"dədə"/"pəpə".
When I learned about ə I saw it everywhere. Pronouncing words with schwas in place of other vowels is what "mumbling" is. The pitch that is a schwa for a child is the same as the "e" of a grown man, but our brains just account for that.
But the coolest thing, to me, is that it's our sound for holding attention. If you were developing morse code or any other form of communication from scratch you would inevitably need to find a way to tell the listener "I'm done talking, it's your turn". In morse code it's ▄ ▄▄▄ ▄ ▄▄▄ ▄ , in radio it's "over", in http it's . In English it's silence, so instead we have a signal that means "I'm still talking, it's not your turn yet", and it's exactly what you would expect it might be.
əəəəəəəəəəəəə...
Kind of elegant, really.
To be fair in my languange (italian), the schwa sound isn't very frequent (i believe but i might be so wrong), but it's used like in english to uhm etc.
Maybe it's because it is frequent in Southern dialects, but my idea is that it's used because it's a neutral sound and places the tongue in the middle of the mouth ready for the next letter. To be fair i Really don't know
This is not the same in most of the world's languages and portraying it as the "default sound" is disingenuous. In *English* it is the most commonly used sound, but that is not persistent across all languages. If you want a more common open vowel, /a/ is much more common in world languages, being attested in 86% of the world's languages (versus the 22% in which /ə/ is used, mostly in European and South Asian languages).
@@luciachayes Hi, is your data based on the occurrence of the *phonemes* /a/ and /ə/ (as the use of slashes suggests)? Because [ə] as an allophone is probably way more common than a phoneme in it's own right.
As a Spanish-speaking person, I can say we don't use schwa for uhming (we don't use schwa at all), we say em, as in EMpathetic. Sometimes without the M, just /e:/. It can also resemble an /ɪ:/ (as in shɪp)
The Spanish, French, Greek, Japanese, Korean and many, many others probably disagree with you. They don't use schwa for their "uhm"s. A generalization like this seems a bit anglocentric to me.
If one of my friends told me that he secretely used me as a test subject to collect data for a vaguely scientific project about how people "uhmm", i wouldn't be mad, i'd be impressed.
Additionally, I'm pretty sure the "experimenting on people" doesn't really apply to any purely observational study (that is, one where the "experimenter" doesn't interact with the test "subjects" and there is literally nobody applying treatment combinations).
@@AlumniQuad I too was a bit confused as to why the presenter claimed to be "experimenting on people without their permission." I don't see how an observational study of publicly available data warrants permission from anyone. It also seems he didn't want to name other channels used in his research without permission, even though these are publicly available names of well-known TH-cam creators and are thus public figures. This is not a complaint as it doesn't impact the quality of the video, it just made me curious ¯\_(ツ)_/¯
@@SynthAir Maybe take this idea to its logical conclusion, for example if your captured data was in fact a video recording of their person walking around, and doing stuff... after a certain point it starts to feel more like an invasion of privacy, which would suggest that it essentially is one, even if what you're doing is on a smaller and less noticeable scale.
Well he's essentially saying that counting their 'ums' was more interesting than the topic of their talk, which is hard to interpret in a positive way and also makes you wonder how much he loves his field of research
And I would just ask: "bachelor or master thesis", as in communication science such studies are not uncommon :D

this is an INCREDIBLY well made. you had no need to put in as much effort as you did for those adorable blender animations, yet you did. holy cow this must have taken so much work but the end result is so impressive
its worth it for the comments like these, thank you :)
@@not_David keep up the amazing work!! they look so professional :)
Exactly what I was thinking all video! I want a master class on visual presentation and animation from the guy!!
exactly, i sticked to see the entire video, absolutely love love that youtube recommended this great channel to me :)
As a military instructor who had to go thru a multi week course, part of which was to learn how to stop using "um" or any other filler word (which you will do when you begin to eliminate "um") where fellow instructors threw objects at our face during a presentation whenever we would use one, I can say I really appreciate this video, and you bringing the self consciousness about "um"ing to the wider world
I don't remember where I learned it, but the presence of 'uhm's can actually improve the listeners' experience. It's punctuation. Punctuation increases comprehensibility. It can draw attention. An audible expression of "I'm switching gears, in my mind, a little bit" can help the audience prepare for shifting their mental gears and follow the train of thought more smoothly.
I 100% agree. I think there were a couple of comments saying that it could be used as a metric of quality because less uhmms is always better, but I disagree with that. I found TED talks really stiff because of exactly this, and i think there is something humanizing about a speaker who uhmmms every so often. Its simply not natural to never uhmm.
For me as a listener, the impact of an uhm depends entirely on why the speaker just uhm'ed. If indeed they're changing mental tracks or need to think over a question during Q&A, then it can help, yes.
However, if they're the type of speaker to uhm every single time their brain has to buffer for even a moment, then the uhm is more like noise to my brain, and I have to actively filter out that noise so that I can actually parse their sentence (but that might be an issue with me as a listener). I think the Loruhm Ipsuhm example in this video is the perfect example of this. This brain-buffering type of uhm may be exclusive to casual or inexperienced speakers, but I'd say that the distinction is still important to mention.
@@baronobeefdip8075 I hadn't made that kind of distinction in my mind, but it's maybe one worth thinking about.
If I were to try to change my speech patterns - do you think a gap of silence would work better in those circumstances?
@@hughobyrne2588 No. Ummms were invented organically as a way to indicate you are gathering your thoughts and someone doesn't need to listen for a second. Awkward random silences would not help. In a way Ummms are respectful. People can rest their brains for a second and wait patiently rather than wait awkwardly wondering why they are silent and if they have anything else to say.
Adam Connover recently had a linguist on his Podcast, Factually. She went into this and many other things in that interview.
I too am fundamentally interested in finding real-world examples of probability theory. This is a great example, and your "why" section at the end completely mirrors my thoughts on why I'm interested in this kind of thing. Wonderful work.
Thank you! I'm glad that theres someone else out there with the same mindset lol
Erm, probability theory is probably the most interesting part of mathematics, along with, erm statistics. ;) Poisson distributions look similar to bell curves, which is pretty cool. Seems like our world can be described by mathematics to a great detail.
so your praise is based purely on the video mirroring your own preconceptions? solipsistic much?
@not_David you could likely get a control group from recordings of the UK Parliament, Prime Ministers questions, committees and debates have different question styles and lengths.
@@sumdumbmick Are... are you illiterate?
6:40 pop quiz for nerds, attempted answer.
We would still observe a Poisson process and the new value for lambda = (1 + p)*lambda
My reasoning is that if you missed UHMMs uniformly, then the process remains a Poisson process. However, the rate = lambda would need to increase based on the probability of missing an UHMM per time period.
Surprised no one’s done this, but after hearing about the premise my first thought was recording the ums in this video so apologies, but here:

wow.... this is the best video time stamp I've ever seen. I'm uhhh... humbled. (crunching the number right now)
Ok, I've crunched the numbers - the average was 14 seconds per uhmmm, while the variation (or standard deviation) was 17. I'd need to do additional testing to confirm but I would say thats pretty close to being equal (I have one data point in the video with average and variation of 15 and 17 and that was found to be poisson, but thats anecdotal).
I am pretty suprised that they are so close. That was very interesting and fun (in a very specific sense of the word). Thank you! We need to upvote this comment haha
Edit: I left a shoutout/thank you in the pinned comment (please let me know if you are uncomfortable with that I can remove it)
Before concluding that this is a fundamental part of how human brains work, it'd be cool to see if the results are the same in other languages. ええと in Japanese, 嗯 in chinese, etc. Specifically I think this could be interesting in Japanese because they tend to use a lot more filler words so it might be a cultural thing and the distribution could be different.
Yeah I think thats a very good point. There has been some really interesting discussion in the pinned comment and the community post, but its more about the uhm itself rather than the time between uhms. I would love to find out
This. So much science studying human behavior tries to draw conclusions from a sample restricted to a single culture, if not an even more restricted subset (e.g. college students) within that single culture. Not that there's no value in that research, but that limitation has to be understood when trying to interpret or apply the results.
Culture is downstream from genetics, realistically most cultural/language differences in this regard, will be downstream from the genetics of the speaker.
Chinese also has 那个, which gets twitter mad lol
Very interesting idea. ...
I love the reference to the Mario 1 frame rule analogy in the bus animation
I was starting to think no one knew the frame rule analogy
@@not_David You even had the flagpole with the stairs, and the pipe, and a store that looks suspiciously castle-like!
What is the frame rule?
@@danielkelsosmithIt's a thing in Super Mario Bros speedrunning, basically the game only checks to see if you've got to the end of the level (so it can start loading the next one) every third of a second
So if you save time but it's not a big enough timesave to arrive for an earlier check, then it doesn't matter, like how if you have to get on a bus at 6pm it doesn't matter if you arrive at the bus stop at 5:35 or 5:50, you'll still reach your destination at the same time, unless you arrive early enough to catch an earlier bus
(Sorry that was super wordy and overexplainy)
@@danielkelsosmith In the first Super Mario game when you touch the flag at the end of the level, the level doesn't end at that exact moment but you need to wait until the next "bus" arrives. The game checks every X frames to see if you have touched it. One consequence of that is that you can touch flags at different frames but you will still get the same time because you needed to wait for the next bus.
I'm so in love with how much pattern-finding there is in the world right now. the Internet is so full of "hey, you know what I just noticed" lately!
pattern-finding is a very human instinct

thanks so much :) I hope its enough to be able to outweigh the fact that I can't produce videos very quickly haha
HAHA. ARRRRIBA!
How do you have time to produce such an incredibly polished video _during_ your PhD?!

aside from the interesting pattern, this is the first time I actually understood what the Poisson distribution represents without just mugging up the formula for an exam and my mind is blown! The beautiful smooth animation and great scripting were the cherry on top, super cool!
I loved the small Super Mario Bros. speedrunning easter egg when you were explaining the bus averages. I thought it was a nod when you didn't just call it a bus to start with but seeing the staircase and flag made me smile :)

I expected the math youtubers, not the Mario speedrunner. Wow.
I would love to see uhmming patterns compared between neurodivergent and neuronirmative people. Whether there is an observable difference or not, I feel like this could help us all better understand each other.
yeah, that’d be interesting. I feel like neurodivergent people sometimes have anti-uhmming superpowers

Dude. I am a current grad student in Biostats and this video gave me the first real world application of probability theory that actually makes sense. Awesome video!
these are my favourite kind of comments haha. I'm really really interested in biostats so I hope many to do something in that area at some point in the future.
Wow, the number of animations and attention to visual story telling is..um..worthy of way more subscribers. Thanks for the interesting content!
I loved this video. As a PhD candidate myself I see very few people who can clearly and simply communicate information that anyone outside of their field/stem can comprehend. I feel as if anyone even with no math could follow this.
Also, I'm betting on Neil being the famous physicist. He speaks so well!
I think you've missed 2 pretty interesting trends - 1) the structured talks from experienced educators generally tended towards platooning (above the line) and 2) when you zoomed into the data at the end, both the QnA and control groups tended towards ideal/low variance random (below the line).
My interpretation is this: the control and QnA chats represent pretty periodic Uhms, being drawn truly randomly. However, the structured talks get platoons of uhms because they "lose their groove" during a talk. Once you say uhm once in a practiced speech, you start spilling over yourself for a while until you get it back.
That was my idea for the practiced part as well. The QnA part being periodic is an interesting idea. I do genuinely wish I had more data for that segment so I could test those ideas. There is a ... game (for lack of a better word) ... called `powerpoint karaoke' where people try to make presentations on the fly to a set of random slides. I would love to collect uhmms during that especially for the professional presenters, but obviously this is much harder to do set up.
The bus joke was top tier. Heard "4 wheeled vehicle of transportation" and I am so glad I got exactly what I expected.
I watched this video just after watching one about SMB1 so it made me pause for a second
@@agar322 Just like the game pauses for a second, or more precisely, until the next bus arrives. Have I already told you to imagine a bus?
Lmao even the brick stairs and the flag were the same during the example lol. 21 frames!

A friend's story, which I'll paraphrase: "One time, many many years ago, during a lecture, a friend drew my attention to a tally in his margin. He would add a tally mark every so often, apparently at random, and was up in the hundreds. The realisation that he was tallying the hesitative noises made by the prof. was, for numerous reasons, absolutely devastating."
My technical writing professor would do this to us when we presented, so I kind of find it interesting to see it done to a prof
Great video. It illustrates the imperative to be able to recognize our assumptions so that we can challenge them. I love that you say science is about asking questions, and it shows when you ask questions about the questions.
this is very fascinating, your research really captivated me and i can't wait to watch more of your videos.
i did not expect to watch this fully, lol
I think a significant factor you did not account for during this is the rate of speech for every person. Adjusting for words per minute and seeing what the true frequency in terms of syllables, words and (sub) sentences is, would give much more insight into how humans actually produce their uhmms.
Additionally using log/log plots for data with a range this small introduces bias in reading the graph. The data can appear much more linear than it actually is simply because in log plots the range of Y values for any given X value that would be appear to be linear to a human eye is greater than the true plot counterpart.
I am overwhelmed by how polished your animations are, how much detail you put into them, and how awesome they look! The layout, color combinations, typeface and font size, the transitions, just about every frame in the video makes it obvious you put a lot of thought into designing it! Keep it up!
To be honest I didn’t understand half of what you said here, but even if I didn’t understand most of it you made it incredibly interesting, I watched the whole video and learned a lot! Thanks, definitely subscribing
This channel is amazing, it uses mundane and simple concrete ways to apply data science and math, in a fun way without throwing away all the math involved,
absolutely lovely, and it already gave me a fuckton of ideas on how I can visualize high dimensional data! thank you so much :D
[*Question primarily for non-English-as-a-first-language speakers!*]
(EDIT) but first - real quick - thank you so much for all the amazing comments. I try to reply to them but there are so many now its really hard to keep up. I'm really not sure where all of a sudden people are coming from and its a bit overwhelming but I approciate it! Thank you again!
(EDIT 2): I havn't had a chance to respond to all the answers in this discussion but learning all the different ways people uhmm in different languages has been fascinating, thank you!
(EDIT 3): Special thanks to @skylercloud3077 (Skyler Cloud) for sitting down and time stamping all the uhmms in this video. The result was a average of 14 seconds with a variation of 17 seconds, so I'd say fairly poisson though more tests would need to be done to confirm. If you see their comment give it a big thumbs up.
The question:
I asked this in a community post but I didn't I didn't appriciate just how different UHMMing (or more generally `filler words') can be across languages and cultures. So 2 questions:
1) What is a common filler word/sound in your language?
2) If you speak more than one language, do you also switch how you UHMMM when you switch languages? (this is the one im really interested in).
For me - english is not my first language however my two languages have essentially merged into one frankenstein language so I can't really test this on myself.
At least for Chilean Spanish speakers I've heard and dealt losts of "Ehhhhhh"
1) In Swedish people say "ö".
2) When speaking English, I still use "ö".
To comment on what @fugo said: Young people in Sweden often code-switch or think in English. So much so that it's gotten its own word, "svengelska" ("Swenglish"). But I've never experienced the equivalent of what Fugo is saying-that is to say, people my age saying "uhm" instead of "ö". A more relevant example of Swenglish is saying "två fåglar med en sten", ("two birds with one stone"), instead of "två flugor i en smäll", ("two flies in one blow").
To expand on this: Speaking Swenglish is often viewed as something negative. There are loads of "letters to the editor"-"insändare" if you want to look them up-about this. So naturally, I think saying "Uhm" instead of "ö" would be getting coverage. However, I've never even heard of it, not from DN or Aftonbladet, Expressen or Göteborgs-Posten. This also points at people not saying "uhm" instead of "ö".
If it doesn't happen in Swedish, I wonder why it happens in Turkish. Although I think the sample size is way too small to draw a conclusion from our comments.
eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
1) Not quite what you asked but I'm British and use "errrr" when speaking English
2) And yes I switch to "hmm" or "uhmm" when speaking my native Indian language Malayalam
1. In German we use „ähhh“(aehh I guess) or a bit more subdued „mhhh“ as a thinking sound
2. I use Mhhh in English as well… maybe Ähh too but I’m not sure about that.
I love the Julia from Drawfee's sun 😊 I appreciate your presentation, it's fun and professional at the same time, not making anybody feel babysat or left behind 🧡
i was not expecting bobby hill in my science video but i'm not displeased
OMG, thank you I thought I was hallucinating that cursed face a second! I rewatched that video yesterday too
I saw him too!!!
I heard Jacob's voice in my mind "Is that Bobby Hill? NO!"
Omg, I JUMPED when I saw the bobby hill stare, this thing gave me flashbacks
I love it when youtube recommends another soothing, thoroughly researched and very pleasant science video to me. 😌
This was an incredibly well produced and informative video. Im impressed! Well done!
I did not expect to to grab a statistical concept that quick. This video is highly educational and reflect the way statistics should be taught. Love it !!
holy shit, how does this channel only have 10k subs??? This is some of the highest quality content ive seen in a while. The animations, the graphic design, the voice over and the information itself are all incredibly well presented.
Thank you for this comment. It allowed me to understand that this channel doubled in followers in just over a week.
Right! I love the style of presentation- it’s very clear and engaging
@@NunoSalvaterra tripled by now
Really? Have you met many people? I live in a rural (please make assumptions) area and I can tell you with 100% certainty that EVERYONE I know would much rather see someone's balls smashed (or even their own) than watch a video with math.
This is delightful, the craftsmanship of your videos and research, and the passion in science, are all on full display. You should be very proud.
Thank you for the really kind words :) Made my day haha
Watched this on a whim when it came up in my recs. Enjoyed the Silly Little Mini Study + stats primer and I feel like my parents would be proud of you if they knew you
(dad's a particle physicist and professor, and mum also was a particle physicist before pivoting careers to do more stats, computational mathematical modelling, and teaching, and does all kinds of silly mini-studies like this for fun on top of her regular work)
Haven't seen your channel before but instantly subbed. Stunning visuals and a very funny yet interesting topic
aw shucks, thanks a bunch :)
I can't wait to see your channel grow, it's clear that you put a lot of effort into this video and it's honestly the most entertaining educational video I've watched recently!
5:08 undertale? you got good taste
I love that you put Mario level parts in the background of the bus analogy. A super specific reference but it made me smile.
“dumb” science is exactly what we need!! how much information might we never know because the question to learn it will never be asked? keep up the unique work ❤
Well now I'm curious about "meta-uhmmm", which I am now defining as deliberately stated "uhmmm"s.
I appreciate that you took the time to do this analysis even though you had no goal in your original boredom. You never know what you don't know, so who knows what ideas you've formed while doing this video or what ideas you've inspired in others.
Awesome video as usual!
Theres this funny scene in a `review' of Doom by Turbobutton where hes recalling a story about stopping into a small store or gas station or something to use the bathroom, and he doesnt want to be awkward about it so he says `uhmm' and he comments in the story about using the `uhmmm' to make himself seem more human relatable to the cashiers, and I couldn't stop thinking about that scene every time I wrote in a `scripted' or `meta' uhmmm haha.
Thanks as always :)
I like that term meta-uhmm. I don't think anyone accidently uses an uhmm in writing yet you still see it anyways.
I also really like the meta-uhm. I spent a LOT of my schoolage life speaking in public (variety of reasons). Around high school sophomore year, I found myself intentionally adding "uhh" and "uhm" into my speech at times. A good friend noticed this and pointed it out and it's stuck with me as something I notice ever since. I do it around people I don't know as well and in tense situations. I assume it's to make myself appear more fallible or relatable? Not entirely sure.
I blame high school debate xD
Uhmmmm....it depends
(Uhmm intended)
There are hilarious examples of people trolling phone scammers hard by uuuuhm-ing almost the entire conversation. Winds the scammers well up. A skilled meta-uhmer can find the perfect balance between baiting the scammer along while also wasting far too much of their time.
This is such a perfect video, you have a great narrative voice, the subject is easy to understand and very interesting, the references are everywhere, the visuals are stunning and greatly used, really an awesome moment spent !!!!
thank you for the very kind words :)
The thing I noticed about this video wasn't the ums but the Undertale music. You can clearly hear OST 50 "Hotel" in the background at 5:33
This reminds me of an experiment I always wanted to see done (maybe it has and I just havent looked into it). Have random people "push this button in a random pattern for 30sec" and see how similar those patterns are. I have a feeling, from loose observation, that there will be similarities (like a quick series of 3 after a longer pause) and only a few people will wail on it the whole time or hit it once and sit back feeling clever.
That would be fun! I'd be tempted to push it at regular intervals and then claim that this was part of an infinite random sequence that only appears regular in isolation.
I’m halfway through and i just have to say the animation is absolutely stunning. i’m having a hard time believing you’re a stem student and have this level of skill within animation. You haven’t credited anyone for help on the animation so i’m inclined to think you did it yourself, which to me is mind blowing, not even considering the amazing information the video contains
I used to be an arts student prior to going into physics and math so I think some of that just carried over. I also just watch a lot of art youtube (arguably more than science youtube)
@@not_David would you recommend and videos, channels or software for doing this sort of animation? it's really uh, punchy I guess is the term but I don't quite think it is? It just really catches my eye and is quite nice and easy to follow.
@@Pulstar232 I don't have any particular channels I watch for that specifically, or rather if there was a video I watched regarding it, it was just from googling and watching the first thing that came up. Its really just about taking cues from other media. For example, I really like watching Marques Brownlee (akak. MKBHD) because his team makes some really smooth animations and transitions, and then it was just a matter of sitting down and really working with animation curves until it felt right (animation curves are the things that set the timing of an animation and they are typically found in most animation software I believe, it is not a blender thing). But it can be anything - I actually find commericals during ads to be extremely good for inspiration for eye catching colors/movement/etc.
Keep in mind a lot of it is practice and refinment as well. If you watch my earlier videos (especially my first) you'll see the animation is very stiff. But you have to start somewhere and get the basics down and then work up. If you watched my videos in order my hope would be you progressively see an increase in smoothness or punchiness as I learned to incorperate those higher-order things on top of the basics as i went along.
@@not_David so it WAS a drawfee reference I saw at 3:49! I thought Julia's Bobby Hill had just invaded my brain and was haunting me across the internet.
I saw this video in my recomended and assumed it was a cool animation about some's published research. Extremely cool to see you did this yourself!
I definitely did not expect to run into the Drawfee's Julia LePetit's Bobby Hill face in a place like this, but at 3:45, sure enough!
My hat is off to you, fellow Drawfee fan
This is a very informative, well-made the video. My favourite part of the graphics was at 9:23 . Whoever made the animations has a clear understanding of animation, design, and presenting data. The script for the video is very understandable and interesting to listen to. I'd like to send my blessings to everyone who worked on this project.
Thank you! "everyone who worked on this project" is just me though lol, i will pass on your compliments to myself.
The bus stop being a low key mario end flag was a great touch
3:50 is that a julia drawfee lepetit bobby hill or do mine eyes deceive me
Small thing, but I really like how your graphs and visuals are angled, it just feels nice on the eyes for some reason. Also, great video, in depth yet understandable for a beginner like me
Wow, what a nice topic! I love the research aspect, the animations, the way your voice sounds is super chill aswell.
Glad I found your channel, thanks for the video
thank you for the kind words :)
The animation is insane. The amount of effort you put in this simple video is awe inspiring
I loved the reference to the frame rule explanation haha. Absolutely wonderful video
yes, we appreciate the darbian reference :)
videos with amazing visuals like these are what keep my brain working
This is my first time watching your content and I did *not* expect Great Days
I was surprised to see this level of quality from this small of a channel.
Keep it up!
Inter-ummm-interval is both the metric and a perfect example. Love it!
Missed opportunity to call it the "inter-umm-interim," though
What a great presentation. I love the shifts in perspective
Love the frame rule reference. Excellent video
The animations on this video are super cool! Great video, amazing execution!
Loved the content, delivery style, and visuals. As a fellow stem phd, I wish I could just award you the degree already. It's videos like this that help me back off from the edge of being completely disillusioned with science. Good luck with everything :)
this comment means a lot to me haha thank you
Incredibly well made video! Loved it!
If my life had taken a different path, and I'd ended up being the academic I'd originally intended to be, this is the sort of phenomena I would wish to be observing, where the seeming random indifference of the universe becomes a little more clear. Excellent work
3:20 I'm not sure what you mean by this, the answer is obviously that you must wait exactly 21 frames between buses
Great video, right on par with the type of creators I'm sure you look up to! You've won my sub 😁
this is literally the best video ive ever seen, the animations, the topic, the metaphor with the buses, GOODNESS. its awesome
high praise, thank you :)
I remember as a kid in the 80's and early 90's, searching for things i wanted to watch. It's both fascinating and scary how these days, things i want to watch find me. Instant subscribe
This video was sooo pleasant to watch. With this level of effort and storytelling, I'm sure your channel will blow up sooner or later.
I subscribed without a second thought, especially because you didn't tell us to do it at the end of the video 😊
thank you :) I did put a small (in text) please consider subscribing but i hope it was not obnoxious. I was worried about it since ive never put a prompt like that in a video and im not a huge fan of those kinds of things
I've had a lecturer, which was a relatively young guy, who'd never say "ummmm", he would talk constantly for an hour and a half, one of the funniest people I've ever had the pleasure of encountering
Dude I had this same idea in middle school when I was bored in class. I thought about how everyone seems to umm for the same amount of time but forgot about it before I could test anything on my unsuspecting friends and family. I’m glad that there are other people out there that think about this kind of stuff.
Good video. I wondered and you were able to fill this void
I would love to see an experiment that takes a transcript, does clustering to find groups of uhms (platoons), then does sentiment analysis/some sort of NLP to find out if there are commonalities in those clusters!
agreed!
I didn't notice the view count or subscriber count on this channel when it popped up and just clicked on it because the title intrigued me, and I was shocked they're both below 100k! The writing and content are great, but the visuals in particular really stuck out to me as exceptional. It often feels like people get carried away with 3D graphics, making them feel distracting and busy (at least to me), but I think you used them the perfect amount to accentuate your story. I like the notebook aesthetic too! Really well constructed video all around :) Always a happy day when I find a new math channel to subscribe to. Keep up the good work!
Thanks so much, those are very kind words :) The animations make the videos a long time to produce but comments like this make it worth it haha
Same happened to me, I thought this was another 100+k science channel I hadn't heard before (that happens surprisingly often). Good job!
Wow what an inspirational and fantastic video. Man, you are so good at what you do and I wish I can be like you one day. Your animations, 3D and 2D. Your knowledge on stats. The way you communicate. It’s all so good. I’m doing my Masters in linguistics and did some filled pauses (um and uh) so you can imagine how happy I am! I also do AE animations but so I can see your effort and art. You earned yourself a well-deserved sub. Thank you!
Thank you for the kind words :) I only had the time to take one linguistics course during my undergrad but it was one of my favourites, so I am low-key jealous of your masters haha
Me2
Such an fun concept for a video. This is exactly what I love about TH-cam
Holy crap how is this channel not bigger yet this video is actually amazing
haha thank you :) glad you liked it!
I had an elderly German professor in college who took a point off every time you used a thinking word he said “if you notice I never use a thinking word, because thinking words illustrate a lack of confidence. I have the confidence you all want to hear me finish my thought and I expect you to have that same confidence in yourself”
It can be a good notion but it is also EXTREMELY boomer to equate use of filler words with lack of confidence.
It’s just a perception that is quite natural.
Some people in an audience are going to have that perception, so it is better to reduce your number of umms to be perceived as more confident.
i love how when you started talking about "imagine a bus stop" there were mario props in the background, which looked like the end of a level. very subtle. i approve.
The framerule reference was amazing; also amazing video but that was probably my favorite part
I don't know if anyone else has this exact experience, but I find when editing a video where you just have a stream of consciousness, you really realise how consistently and frequently you say "ummm".
15:34 I sense a fellow drawfee fan 😏
Also I really liked your video! My theatre teacher back in middle school taught me to stop saying um when speaking but since it’s been quite a while since then I wonder where I place on the chart now 🤔
you should test it haha I'd love to know!
This reminds me of a story of a public speaking class where they were very specifically training the participants to avoid "uhm"s by blowing an air horn every time they "uhm"ed in a presentation. The point was to learn to project confidence and professionalism so uhm that's pretty cool
this video give me new perspective thank you pal
7:42 Ah, hello Gordon!
I love the way you explain stuff! Also the mario speedrunning references are really clever. I haven't seen any good references to it before.
Hello! Just fond your channel! ABSOLUTELY LOVE THE MUSIC YOU USE! so fun regocnizing and super hunoristic enjoyed the video ❤❤
thank you :) I'm glad you found it fun to watch
This is awesome. A friend and I used to count the number of ummms our science teacher used to say in our junior high school science class, per class, per day. We never did anything with the data but we would compare the number with each other in passing in the hall. It kept us awake. That was a few decades ago.
