Here's Brady's Antarctica video linked at the end: th-cam.com/video/o71TFQBTCG0/w-d-xo.html
I was just thinking this morning "These guys haven't uploaded in ages...", I was beginning to suspect that Brady's heart had been stolen by the Royal Institute.
Periodic Videos Tritium works on photovoltaics
HI :D
Periodic Videos with a small radioactive isotope and phosphorus phosphates with solar technology and neodymium magnetic induction could power a mobile phone instead of a lithium battery and it wouldn’t need to be charged for years 🤔
Very informative. I am just curious how laboratory (non-radioactive) waste and apparatus (beakers & flasks) are taken care of, any video hint
"So you see brady, you're really clever" HHahahhahahahaha of course he kept this in the video
Should have been the title.
or "a very long time ago" xD
Hey, if i had video evidence of the peofessor calling me clever, i would do the same! Haha
That remark once again shows the professors remarkable feeling for guiding his students
Dude right at the same time I was reading this, he was saying it 😂😂😂
The Professor’s giggles are everything!
The Professor makes learning fun again. Even for old folks like myself.
Thank you!
Prof Poliakoff is a lovely man.
His delivery is so melodic and soothing.
I have learnt a lot simply by being able to absorb what he offers.
"Still a very long time ago!"
savage
That comment almost derails the entire video!?
He is about to show him a very long time ago
Between the discovery of amber and antipasto?
The jump cut right after is probably cutting out the Prof calling him a cheeky fucker :D
1:45 Half Life 2.62. Almost there!
HL2E3 was going to be the last third of the 3 part series, so 2.62 is still within episode 2
Promethium 145 Is 17.7 Years
are you happy now?
boi do i have news
@@kubeek lol
If your pacemakers battery cools down far below body temperature you don't really need it anymore anyway, do you?
Yes, I was thinking about that... temperature stability is not an issue with implanted devices...
Unless you are looking for a superconductor; then it must stay at cryogenic temperatures.
Droplifter, you need to check their video on negative temperatures.
My pacemaker battery is below body temperature. You're right, I don't need it anymore.
(My pacemaker was removed while receiving a heart transplant 23 years ago. I still have the pacemaker as a souvenir.)
Duane Degn Happy to hear that. Also that's a pretty badass souvenir :)
May it always stay one! (but after 23 years, I think it's safe to say that you won't need it anymore)
Sir Professor, it’s great to see you again. You still look well and vibrant. I always look forward to your videos. While electronics engineering and physics have always been my two main areas of interest, you have ignited my interest in chemistry with your videos. Thank you and take care! :-)
These videos are always so wholesome. Just an elderly scientist who wants us to have fun and enjoy learning science/chemistry. He is in my opinion a hero.
If I had a teacher like this guy, I may very well have gone into chemistry instead of Mechanical Design. All teachers should have the love of a subject like him. I never realized the importance and usefulness of chemistry till I was older. Now I use it for Plating, metals finishing, pyrotechnics, gardening, etc. So many things that interest me ended up tied to chemistry.
HE LIVES!!!
John Benjamin Tatum I began to be slightly worried bout him.
I met him in January. Went all the way to University of Nottingham just for this opportunity
Loooooool
3:37 is it just me, or is the professors giggle rather contagious?... :-D
Brady made the professor lose it!
These videos are freaking awesome, I think I have honestly watched all of them at least twice now.
I love Professor's laugh
We've finally found out that science is 73 years old!
I missed you professor
i love the professor. i hate watching him age more and more though :(
Inevitable law of life! We're all getting there
Unless we quit first
Oscar Villavicencio aging is not inevitable. Advances in genetic engineering is well on it's way to ending aging
ah yeah I feel the same way,he's a national treasure,a world treasure......a PERFECT example of a great human being that exists to help those willing to learn with nothing alteria going on whatsoever!....top lad!
The half-life of human populations is 76 years.
Yes finally, you’re back:)
can u sub to my channel please
@@ivanemmanueldadacay2913 You can't just ask people to subscribe to you, You have to make videos and then wait for people to become interested and then they will sub to you.
1:26 Translation:
About the Element with the atomic number 61
by Luigi Rolla and Lorenzo Fernandes
The search for the yet unknown elements of the 5th period that, according to Moseley's studies have the atomic numbers 61 and 72, has received attention in the last decade.
The Problem about the former element (note: Maybe they meant "latter") has been solved in the year 1923 by Coster and Hevery by the discovery of Hafnium. The Element 61 though is not yet discovered.
i was wondering why italian scientists published in german? :D maybe soth-tyrols?
Germany was sort of the center of the scientific world until the Nazis decided they didn't _want_ to be the center of the scientific world if it meant admitting that most of their best science was done by Jews. The Americans and Brits decided they didn't care as much and were happy to take over leadership in science if Germany was done with it. The standard language of science has been English ever since.
Thank you !
I really enjoy watching your videos even though I'm just a normal joe who doesn't really know a lot about chemistry. I don't think I'd be as interested if it wasn't for someone like the professor to present it to me in these videos.
Imagine if more teachers were like him
It makes me feel warm to see the professor get such a good laugh in there.
All jokes aside, the fact that this sort of information delivered to me by experts is free still blows my mind. Thank you
Absolutely love this channel~ Learning so much about Chemistry here. It's fascinating.
I've watched hundreds of videos on this channel. This might be the first time I've seen Professor P laugh.
He is the most adorable and chilled out person I know as a professor.
Dang you still have every important book you bought as a child?
Glad to know I'm not the only knowledge hoarder out there.
I keep forgetting this is an element. I think of the flamer fuel from 40k before I think of the element.
Onno Inada same
?
Surprised gw hasnt tried suing iupac over the name of promethium lol
That'd be a hard lawsuit to win given that the element was named Promethium long before the game came into existence.
Same here.
I am currently preparing for my studies in chemistry and were learning about Döbereiner, Moseley, Mendelejew and Meyer. This is so interesting. And the completion of the periodic table is still continuing.
I love when the professor gets excited.
TIL: Mendeleev didn't believe in Electrons
I absolutely love this series of videos. Thank you for your hard work and sharing.👍❤️
"Cyclonium" was probably related to the instrument of its discovery, a cyclotron.
Sounds like a funfair ride, not a legitimate scientific apparatus.
That's what I was thinking.
your videos make me inspired to keep learning chemistry, ive been binging them for the past 2 hours!
I see new periodic video I like.... I mean I don't even care much about chemistry until I watch one of these videos and I get hooked
It's a sheer joy to see prof and science never ever fails to amaze me all the time ⌚ 🔬😁
Last Thursday Isaac Arthur's SFIA episode covered batteries and energy storage devices. It's one of his best episodes IMO.
-Jake
Man, he's getting old... I'm gonna miss him and these videos
These new videos are looking great! You really brought some interesting information even though we could not see a chemical reaction.
I would love to take a chemistry course from this professor. Chemistry has been a life long passion for me.
always waiting faithfully for the good professor to put these out, love these videos
uploaded on my birthday. what a day....
Deadbush Happy Birthday my dude
In 60 years you'll tell your grandchildren that, and they'll reply, "Still a very long time ago"
HBD Dude , Have a nice day!
Mine too :)
I don't have a huge understanding of chemistry but I love the professors voice it seems so kind
so nice to know you are still active on YT
What a name, and I never realized it. I'm a sucker for names that have real meaning behind them, and the idea of naming an element connected to the nuclear bomb program after a man who stole the gods' power just really makes happy.
Professor, I would like to help you out. Promethium's longest stable isotope is actually Promethium-145 and has a half life of 17.7 years. ;)
Big difference of 2.62 half year and its 17.7 yrs😳🤷🏻♂️🤷🏻♂️
Professor.. It is very nice to see you and learn from you. Once again Thanks!!!!!... Cannot wait the next video.!
I wonder what my classmates are doing this summer. I am studying the periodic table, to prepare for high-school.
Did he get new glasses? Or did he get a haircut? Or has Martyn been replaced by a clone that looks slightly different
The exposure/white balance is a bit different IMO...
It is the Martyn-isotope 137, slightly different in valence hair configuration
Axel Zeit I think he is either cis-Martyn or a trans-Martyn
He has isomerised
MrEmrys24 I'm not sure if he's an enantiomer or an diastereomer of Martyn....
My all-time favorite! The professor shows surprise. So funny.
It's always nice to me to see elements that are radioactive but last quite a while
Like you got elements that barely last half a nanosecond and then you have Promethium that lasts a couple years
The promethium battery is a cool idea, and I seem to recall someone tried to make a similar battery out of tritium. Was that Nurd Rage?
The other thing I was thinking is that phosphors aren't just for old TVs; most of the modern LEDs produce blue or ultraviolet light and then use phosphors to give white light and other colours.
Yes, that was NurdRage who made the tritium->phosphor->photocell battery.
CFD lamps and standard fluorescent tubes also use phosphors.
2.2% formation in uranium-235 fission...
I am very happy you talked about batteries since is my field... I am on the team that is developing a pm-147 battery... you explained it perfectly
Thank you Professor and colleagues I was taking notes and paying attention.
3:41 My all time favorite moment. "Still a long time ago"
Love watching your videos! Great lessons
I have little scientific education to speak of. But,I have enjoyed watching the videos because the professor is awesome. You make this accessible to the masses, which is a staggering accomplishment on its own. Thank You.
Makes me happy every time I see a video from the Brady team. Not only do I learn new stuff, but I learn with a smile (or in this case with a laugh)
Thanks you guys.
Clicked on the notification so fast
Matthew Taylor never heard that before
Why is this atom and Tc so unstable?
No isotopes of Tc or Pm are beta-stable, which means that there are no isotopes for which the number of neutrons prevents neutrons decaying into protons or protons decaying into neutrons
They're pretty odd, and their neighbours are stealing the stable isotopes from their isobars.*
*the explanation is not this simple
I would love to hang out in this guys' office for a day and listen to him talk about elements. I don't know much about the subject, but that would only make it better.
Bro this guy is so wholesome. He just loves chemistry
Very good video! As always, interesting and captivating, thank you!
The laughter of the professor made my day
I like to watch the videos on the elements. One thing I hear often is about the predicted properties of yet undiscovered elements missing in the periodic table. Make a video on the heavier elements beyond the 100 elements: what is the highest atomic number for which current science can predict its properties? What do we expect to find at the "island of stability"? Is there a stable element with a higher atomic number?
Honest. I feel a tad embarrassed admitting this, but my search for information on Promethium started with a video game. Empyrion: Galactic Survival.
Grateful. I’m glad to have found your channel. You get a like and subscription. I look forward to hearing more. What an interesting element this Prometheum is!
Love these videos! I’ve watched the plutonium video about 100 times, lol.
Promethium sounds like an element good for lighting.
The added electrons as you go through the lanthanides generally go into inner shells, not the outer (valence) shell. That makes them chemically very similar (and hard to separate).
I could listen to this guy talk all day.
Miniature RTGs using Pu-238 were also used in pacemakers. Most of the RTGs were made by Alcatel in France.
I am so happy i found this channel! :)
Perhaps the name cyclonium was in reference to the cyclotron machine that has been used to synthesize many new elements? Thoughts?
Or used to separate elements by mass spectrography. But seemed obvious given the subject and era.
This is probay the best chemistry channel ever, i used to hate chemistry
5:20 "which can interact with the acid, to form assault" - I guess some interactions with acid could be considered assault :)
"How to synthesize your own AR-15"
@William White: Didn't the smiley give it away that it was just a silly joke?
"There were zwei peanuts - walking down the straße - und wun wass - assaulted! Peanut."
Like a boiling cup of it thrown in your face!
Element themed tie? Consider me subscribed.
Thanks for those facts. My friends were, indeed, very impressed! :)
This was a very cool video thank you Freddie and professor could you please do a video on Mendeleev not believing in electrons and what do you think about it , thank you for your hard work can't wait to see what you do next time , greetings from Iran
Thank you for your knowledge Professor. Is #61 magnetic? Promethium has 'fission' potential...
Nice fun facts at the end Professor! Thanks.
I LOVE these videos and I LOVE this guy! Xxx
Promethium was used in the betavoltaic battery. The electrons directly drove PN junctions. Using a phosphor to create light to drive a PV is used in the optovoltaic battery.
For interstellar missions Carbon 14 is being considered because of its very long half life.
The professor! As always fun!
i love all your vids i have always wanted ty know about common household bleach what makes it remove stains etc. ill bet you could do a great show on it.
Promethium has a very special place in the measurement of basis weight in light weight paper production. Usually less than 100 gsm. Krypton does not have the resolution for very precise measurement. Process control systems have been using it since the early 90s. How would I know? Because I was there.
PS using more krypton does not improve the resolution only the signal to noise. Beta decay is not a continuous stream of electrons.
"We found a new element, no big deal."
Element 61...Meh!!! 😂😂😂
Some of your videos are used in my science class and i love it. Everyone else just laughs. We are only 11 and 12 year olds
I love to see some information on the people we see in the videos. Can you give us some biographical info on them please?
I love this guy! Should nickname him 'Albert Two'. lol
super cool stuff, I have watched every single video, many more than once
Can you do a video on Rhenium Diboride, Wurtzite Boron Nitride and ultrahard fiends and why they are so hard?
I remember in undergrad doing ion exchange chromatography. Fun times.
I love watching his video's, I'm nowhere near smart enough to understand most of it but its so fascinating anyway
Finally a video from the smart side of TH-cam! I love the name of Promethium but it is impossible to get. In US and EU U235 and U238 can owned I think.I want to see a video of White P and Mg reacting some day.
What a dear, dear man. May we all and each of us know someone like this in real life.
I love when Oak Ridge is mentioned, it is an amazing place with such an amazing amount of intelligence.
Yes! A new video!
So happy the updated video is out! I love watching these videos
You made the Professor giggle, that was WONDERFUL!
