Here's Brady's Antarctica video linked at the end: ruclips.net/video/o71TFQBTCG0/видео.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!
"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
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.
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)
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
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.
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! :-)
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.
Brady made the professor lose it!
These videos are freaking awesome, I think I have honestly watched all of them at least twice now.
3:37 is it just me, or is the professors giggle rather contagious?... :-D
I love Professor's laugh
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.
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
Absolutely love this channel~ Learning so much about Chemistry here. It's fascinating.
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 !
We've finally found out that science is 73 years old!
It makes me feel warm to see the professor get such a good laugh in there.
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 absolutely love this series of videos. Thank you for your hard work and sharing.👍❤️
your videos make me inspired to keep learning chemistry, ive been binging them for the past 2 hours!
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.
always waiting faithfully for the good professor to put these out, love these videos
It's a sheer joy to see prof and science never ever fails to amaze me all the time ⌚ 🔬😁
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.
He is the most adorable and chilled out person I know as a professor.
All jokes aside, the fact that this sort of information delivered to me by experts is free still blows my mind. Thank you
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.
Professor.. It is very nice to see you and learn from you. Once again Thanks!!!!!... Cannot wait the next video.!
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
I've watched hundreds of videos on this channel. This might be the first time I've seen Professor P laugh.
Thank you Professor and colleagues I was taking notes and paying attention.
I love when the professor gets excited.
I don't have a huge understanding of chemistry but I love the professors voice it seems so kind
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.
Love watching your videos! Great lessons
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.
Very good video! As always, interesting and captivating, thank you!
so nice to know you are still active on YT
My all-time favorite! The professor shows surprise. So funny.
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.
Last Thursday Isaac Arthur's SFIA episode covered batteries and energy storage devices. It's one of his best episodes IMO.
-Jake
Love these videos! I’ve watched the plutonium video about 100 times, lol.
I could listen to this guy talk all day.
Nice fun facts at the end Professor! Thanks.
The laughter of the professor made my day
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!
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
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 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.
I am so happy i found this channel! :)
So happy the updated video is out! I love watching these videos
super cool stuff, I have watched every single video, many more than once
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.
"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.
I LOVE these videos and I LOVE this guy! Xxx
Thanks for those facts. My friends were, indeed, very impressed! :)
Man, he's getting old... I'm gonna miss him and these videos
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?
This is probay the best chemistry channel ever, i used to hate chemistry
Finally a video from the smart side of RUclips! 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.
I love watching his video's, I'm nowhere near smart enough to understand most of it but its so fascinating anyway
3:41 My all time favorite moment. "Still a long time ago"
Bro this guy is so wholesome. He just loves chemistry
Fascinating series and a great speaker. Wish my chemistry teacher at school was this enthusiastic.
The professor! As always fun!
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
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
🤷 It's just how it goes
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
You made the Professor giggle, that was WONDERFUL!
TIL: Mendeleev didn't believe in Electrons
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😳🤷🏻♂️🤷🏻♂️
I love these videos because they are usually nothing to do with politics or drama or anything like that. It is just facts and interesting ones about real things. From a fellow rock collector.
Very interesting especially the use in pace makers.
That tie is amazing
I love your videos I could listen to you all day.
Did you ever meet professor Stephen hawking?
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.
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....
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).
Oh, I love him so much❤️
Sir, you make me wish that I had been born in the same time frame as yourself.
I love when Oak Ridge is mentioned, it is an amazing place with such an amazing amount of intelligence.
Thank you for your knowledge Professor. Is #61 magnetic? Promethium has 'fission' potential...
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.
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.
Promethium sounds like an element good for lighting.
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.
Yes! A new video!
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.
What a dear, dear man. May we all and each of us know someone like this in real life.
I love to see some information on the people we see in the videos. Can you give us some biographical info on them please?
Sir Martyn, thank you!
Miniature RTGs using Pu-238 were also used in pacemakers. Most of the RTGs were made by Alcatel in France.
Element themed tie? Consider me subscribed.
Please science, keep thius mastermind genius alive and with us to enjoy life as much as possible for as long as possible. All hail and praise the doctor.
