This was great.
The lady really knew her stuff and presented it in a wonderful way.
Thank you to both you (Brady) and her.
@themightychickens glad you enjoyed it... thanks the astronomers, not me! :)
This is so amazing and well explained, that I watched the whole video
That's saying a lot for modernity haha!
@aMondia yes, I occasionally ask for help on Twitter and Facebook!!! Thanks to everyone who helped!
This makes me realize how beautiful Earth really is.
I've been watching sixty symbols vids for the last couple days and I have to admit, I am SO, so so so in love with her
Probably my best spent 11 minutes ever on the internet. Thank you Brady.
10:01 Aaaahhh!! What kind of transition was that. You almost made my head explode.
Kind of distracted bt the atlas of creation in the back
He did a video on that.
Very interesting video. Thank you !!
Maybe the young man could talk a little bit slower? ;-) I found it difficult to understand all he was saying, since english is not my mothers language.
English is not my Mothers lanuage but it is mine and i had to relisten several many times but then i had a thought, put the subtitles on
She pronounces everything so delicately. Its very nice to listen to.
Vsauce and Sixtysymbols - some of my favorite things merging together. Amazing.
VSAUCE?
What would life b like if the earth wasn't tilted? That would be a great video
andre bolto More interesting question would be, if we vary tilt of the earth by different degrees, how much would it change the weather patters? There must be an equation or at least a mathematical relation between the two.
It would be spring/harvest equinox all the time. Which means only spring all the time and no other seasons!
probably one of the best youtube videos ive ever watched
lovely video as always! thank you brady for your effort
This pretty much proves that the Earth isn't flat.
You haven't heard the full flat Earth theory then. Flat Earthers have a counter argument for this stuff. Sadly, Occam's Razor is lost on them.
Occam's Razor and the term "ad hoc argumentation".
~Flat Earthers have a counter argument for this stuff~ and boy, is it complicated! This video should be mandatory in every school in America.
hopefully i marry a lady as pretty and intelligent as she is.
daft bes me too hope so
This piece of knowledge had always been a dark spot on my mindscape, even though it's more relatable than most other science topics. Well, now i do. Thanks sixtysymbols!
Thanks so much for uploading the video.❤️
these kind of videos need millions of views these actually teach you something.
I know Nottingham very well. My Moms sister resided in Mansfield. I recall as a child picking Blackberries and Mushrooms in Sherwood Forrest. Decades ago.
They are now deceased, I miss my cousins, as we are now older than our aunts and uncles were when we we kids.
I recall rushing for that Shilling to place in the Meter as the Electricity went off.
Hi
Excellent presentation . Thank you!!!
I just loooove the way she explains things; just love her!!!
Celestial Mechanics perfectly explained, no equations, no tricky software, just pure intention of making this as simple as possible but comprehensive. Thank you.
Geez why is everyone trashing this video x.x..if you dont like it, lean "forward" and change it! Some of us actually enjoy this and dont really care whether or not you "learned this back in kindergarten"
Amazing video!! Thank you so much, from Mexico!
Been subscribed to Sixty symbols for I don't know how long.
Does the Sun rise due East in Antarctica at the equinox?
Shut up. I was subscribed to this channel way before vsause. this is probably the most educational 11 minute video on youtube!
Her voice is so soothing!
Not only is she beautiful on the outside, she's knowledgeable too. All the professors in the videos are a joy to listen to.
whoa......lots of information.......11 minutes to understand it all.....
This is better than school!!!
Subbed!
Getting in a few days early because I am away for the solstice itself!!!
Where was the photo at 9:20 taken? It is interesting how it has "Ráktérítő" written on it in Hungarian.
+CsBence98 According to the hungarian wikipedia, somewhere in Western Sahara.
Minor corrections: She pronounces the word "analemna". It is "analemma". Later, when describing the motion of the sun around the polar sky, the presenter uses the verb "rotates". The sun actually appears to "revolve" around the north pole.
@sixtysymbols I've always been interested in solar movement. Great video.
Can you do a video on the Higgs Boson?
Never thought I would watch the whole video!
Thanks for the info! I've been wondering what software this is... I'm going to look it up now.
@paloskie but I'd like to add it to the video here for everyone!
nice work !!
this is the best explanation on the internet
Yay for using Stellarium! I use it all the time when I'm gonna get out my telescope :)
great video, very entertaining and informative.
This is a really cool thing I've never really thought of. The program really helped with getting the point across. One more thing in life explained =]
@busterbox I'm pretty sure this is "Stellarium". It's open source and available for most operating systems. Haven't tried it in a long time though.
I watched it all, i didnt realise how long it is. interesting stuff
thats so interesting!! i love this!!! i thought it would be boring! but i loooove it!
this was a really great video soo informative great work guys
And now I just wanna go and watch Sagan all over again.
@kid181 That effect is actually negligible in comparison. The difference in distance is only about 2%, not making for a large change in sun radiation (about 4 percent). And on the south half of the earth, this effect actually goes opposite the seasons, not to a noticeable effect (further away in warm season, closer in cold).
@paloskie gracias! Luckily i got VLC installed and will give it a go this weekend.
@carbronica Crumbs yes! Now that I've looked at it I think I was somewhat perplexed by this many years ago but have since decided to forget all about it. The base unit definition of an ampere does look suspiciously derived to me but from the meter and the kg not the Coulomb. Interesting to note the proposal to define it in terms of Coulombs in the future, with a new definition for Coulombs.
holy crap this is amazing.
Thanks so much for the video! :) I learned a lot! :)
One question,(1:55 - 2:52) That also explains (in part) why there isn't summer time in the countries that are under the ecuatorial line?
those romans are geniouses. Ive been suntanning for years and never noticed the solstice.
Thank you thank you thank you. I've always wonder about solstice.
@carbronica "I've always wondered why theCoulomb wouldn't therefore be the base unit instead."
It is.
It just seems to be convention that sometimes we like to used derived units like Amps instead of Coulombs per second while other times, like with velocity, we are happy to talk in meters per second or miles per hour without feeling the need for a new unit.
How nice of the viewers to send in pictures you can use. ;D
I love her mixed accent, great to listen to :)
I am a greek astronomer 2000 years after Eratosthenes , Ptolemeus and Hipparchus and I approve this video on behalf of my ancestors.
This is fascinating. o_o I want to learn more!
Dear Brady,
Could you ask the Physics Guys to give their impressions of 21/12/2012? :D I want to see their impressions on the subject and what they think of the galactic alignment.
Thank you, keep up the great job!
this is the best one.
Great calculation for that that guy in egypt; just brilliant!
I wish this woman was my Geography teacher or something.. it's so easy to listen to her talk. I'm sure my Geography teacher was saying something along those lines once, but she somehow makes it seem more interesting :D
Stonehenge as a solstice calendar. Well, that IS pretty cool.
But I thought it was an intergalactic marker for a large black and green puzzle box called the Pandorica?
Brady, do you know what that software is that she was using on the computer?? I need to get it!
Agreed, I came here to say the same thing, she has such a lovely and calming voice. Also, that software is really cool. I wonder what it's called. (Haven't finished the video yet)
How could the date of the sun rising in the video be june 21, 2011. when the video was uploaded jun 16, 2011?
Excellent Leanback.
this is really intresting and also very well explained! i love it, my teacher at skool when i get bakk needs to show us this so skool wouldn't b so boring =)
That is one nice mac you've got there.
That's rather impressive software you've got there. What's it called? Any idea how it works?
Uranus has a tilt that is nearly pointed directly at the sun (almost a 90 degree angle). You should look it up!
@buzzimu I dont know what is it. Same happened to me. I think its her voice. So calm and pleasing
btw thats stellarium if anyone wonders what program that is.
Timely! :) Why do the latitude and longitude lines projected on the "celestial sphere" appear to move as you move throughout the day? Shouldn't they appear to stay in the same spot?
Could you do a video on boiling points? Why water boils faster on lower pressure etc and generally what causes solid, liquid and gas state :D
That's pretty awesome
@sixtysymbols What is the name of the software being used? Is it commercially available?
The programme she is using is called "Stellarium" if anyone wanted to know ^^
@sixtysymbols can you please make a vid on the green flash?
at 10:50, what is Harun Yahya's 'Atlas of Creation' doing in the book shelf? Just a curiosity?
brady! another amazing video.! What is the name of the software she is using?
By the way guys the software she uses is free and is called "Stellarium", available on mac, pc, linux, and many mobile platforms.
im probably wrong but didnt she say the distance between alexandria and seren or what it was called wouldve been 1/50 of the earth
and then she said they measured it and it was 4% of the earth
but 1/50 should be 2%
or did i missunderstand something there?
i am so enlightened.
@BomberEffect not recorded on june 26th. she just set the date on the computer to show the sun on that date
@TomMarAlem1987 What happens exactly? If a photon has specific wavelength, a wavelength small enough, so that its energy is big enough, it will give enough energy to a electron to overcome the energy gap in between atom orbits. U may have some Compton scattering involved, but that is a wide very wide subject.
@lnwreal9 This only happens for like 20-30 days out of the year, it is not year round. also there is also like 20-30 days of night as well at least thats what i think
Very cool.
@XxFairyGrrlxX If you're talking about the date at the beginning that wasn't the actual day. She plays with the date throughout the entire video, that's how she gets it where she wants it. She started on the 21st because that's the summer solstice.
The name of the software is stellarium (Mac) and its free to download
Sorry but what did you mean by the sun was in the constellation of cancer. Like during the solstice ? And if so why is the Tropic of Capricorn named so ?
Opposite hemisphere, for the southern hemisphere's summer solstice?
@pkwithobby yep thats why it had stone henge at the beginning
@extremebeyond probably. I'm not from around there, so I wouldn't recognize the differences in voices, all I hear is a similar accent. Though the pitch even sounds like you to me. But since it's you replying saying it isn't you, I'm guessing it isn't. Thanks for clearing it up! Didn't think you had anything to do with the Cosmos.
If you wanted to download the program she was using it is called Stelarium and its free.
