I haven't had a chemistry class, thought, seen, breathed anything chemistry in like over 15 years. This was an absolute delight and refresher on many things forgotten, ty
Chemistry left me so cold in school. I wish I'd had lectures the likes of this when I was a student. Absolutely wonderful.
Gosh, I feel the same. The periodic table was not explained to us at all (UK in the 1970's-1980's), and we didn't have the fundamentals. I switched off.
I left Chemistry and Biology cuz they only concentrated on memorizing some random reactions, drawing some body parts etc.
So I agree.
Same. I had awful chemistry teachers
Trane Francks fortunately i did have these type of experiments in high school. But now you’re seeing it hope you can still enjoy and be fascinated enough to ask why is it so?
cx& ;)¿
These lectures for kids are always so informative, and no one's trying to sell you their book.
Kids? Man im in my 70zz and it Hurts my head. It HURTS IT HURTZZZ
@Martin Jansen uhuh, and that being what is for ????
If for example Sean Carroll tells me how the universe works he can plug in his newest book as many times as he wants.
And no one's trying to sell me a Jaguar this time lol!
*Richard Dawkins would like to know your location*
Chemistry is literally and figuratively the only way to end with a bang! Thank you, RI.
Love seeing the children actually excited sitting and watching through all this science. Marvelous to see young ppl engaged with science.
The bonding simluator explained me a lot. What a great educational tool.
Another great talk aimed at a younger audience introducing the wonders of chemistry, well done to Dr Wothers and the RI.
So much fun. I graduated in chemistry and never saw such a cool lecture.
What you doing now? Analytic or organic? :) im a 3rd's year student.
That's because this is put on by the Royal Institute.
Same here mate, they made the periodic table boring but it is such a remarkable arrangement
really, i didn't even get my minor (3 credits away but couldn't be organic, I loved organic too much to strive for a sidenote on a piece if paper) and I did all these experiments (except fluorine) myself. Alkalis with water, mirror, decomposing and recompising H²O .... Then it got even cooler, using H²CCl² regularly, crystalization, spectroscopy. Those were the days.
Did you enjoy the labs or (as I often observed) did you try to get through them as quickly as possible.
I say this because I hypothesize that many remarkable phenomena go unappreciated by trying to "get it right'" or understand the math your expected to preform (very basic, but many chem majors loathe math and hence don't retain it, so in some sense they learn it all over again in chem). I loved lab and fell in love with chemistry all over again, eventually somewhat regretting my choice if major. But maybe it was the way I walked that path that allowed me to experience the experiments in a way much more akin to discovery than a required curriculum. (Especially as much of my chem was not required or even counted towards a minor and I was too far and too in debt to major at that point. I just kept taking all the ochem they would let me.)
thanks to chris brackstone for his tireless effort in preparing these lectures
Huiiuiuihihihihihihiihii
Fascinating, clear and well presented. As a layman, I now have an understanding of why the periodic table is arranged the way it is. Thank you Dr Wothers.
It's High School education.
Mee too
I would have loved to have seen this when I was in school. A lecture like this could easily turn a kid toward a career in science. Both informative and very entertaining.
totally agree with you!
Amazing never thought would sit through 1+ hr of pure chemistry 🔥🔥🔥🔥🔥👍🏼👍🏼👍🏼👍🏼
You’ll definitely enjoy Andrew Szydlo’s lectures at the RI too!
@@monika.alt197 Andrew Szydlo is an excellent science educator, love his presentation. I can tell these educators such as Peter could be influenced by the man that inspired me to become a scientist- Bill Nye the Science Guy himself ❤
Magic of internet anyone from the world can view these so awesome
I always loved chemistry and, in fact, almost went studying chemistry at university. I've had some very good teachers, but Mr. Wothers takes it to a completely new level. Thanks for this very interesting lecture.
Dr Wothers. Very good presenter. I've seen many of these presentations and he is easily among the most entertaining while doling out a surprising amount of information.
I prefer Szydlo from a purely stylistic point of view, but the RS's lectures are all excellent. Accessible and informative, while still being quite entertaining.
@@mmmhorsesteaks I agree 100 %.
@@AnoNymInvestor I agree 100% as well!
Wonderful lecture! Well done! If this video doesn't get a few hundred kids into chemistry I would be amazed. Maybe one of them could be a Nobel Laureate?? Basically all chemists just love bangs! :-)
That's remarkably incredible lecture i'm a 4th grade chemistry major and of course know almost every thing been said in this lecture but what amazed me that the way he say the information that even make kids understand really difficult concepts
Much respect❤
Thank you @The Royal Institution for uploading these marvellous and content rich leactures here on youtube for free. We are really very fortunate to watch and enjoy such great experiments done beautifully by these knowledgeble professors. I hope we could get such curious environment in our schools also so, that student can explore the beauty of chemistry which is far beyond just few chemical reactions which they cram for their exams.
This one is fantastic in many respects, behind the didactic and impressive experiments, lots of science, history and even modern discoveries. For instance I never heard of explosions induced by Coulomb's force before. Surely one of the best conference here for a long time !
Yes - That's the way to teach and entertain at the same time. Well done.
This video is amazing! I get bored real easily but I watched the whole video no problem
I gleaned more from that 85 minute video than I learned from high school chemistry. I believe, it's all about the quality of the teaching. A teacher has to either possess the ability to actively engage her students in the subject matter or the university must teach it as a necessary skill.
If you want more information about the coulombic explosions you see the actual discovery experiments as one of the team is youtuber Thunderf00t.
I think the thing that makes the difference is that the properties of the groups can be explained by the valencies, and in particular the number of electrons in the outermost orbit. When I asked my chemistry teacher why certain reactions went the way they did, his best answer was 'that's the way it works'. It's so much easier to understand when you have a 'why it works' rather than just the 'way it works'.
@@drmoss_ca I'm sorry to hear that, if your chemistry teacher really did just respond like that they have no business pretending to understand chemistry at any level a child will be examined at. We learned this stuff at 14-15 at my school, but that was last century :)
I suspect my experience was a little further back in the last century!
We used to teach rhetoric to people, which is all about effective speech. These days, it's much more haphazard, as teachers have to rely on their natural abilities instead of a trained skill.
Utterly brilliant and I think every child on earth should get the opportunity to watch it.
Those doing rocket physics do.
This was the most beautiful lesson on periodic tables I have ever attended/seen.
The way this guy pronounces "order" he could very well be speaker of the house of commons...
Good stuff. Fun demonstrations. I bet those kids had a blast.
42:42 "and my rod has gotten much smaller"
*muffled laughter*
Sounds like a line from the Bible..
Chemistry teachers always have an unfair advantage because there's literally always a good reason for them to set things on fire
I could listen to his lecture for hours because of his voice.
“Physicists, of course, love smashing things even further and breaking everything”
Yeah, you would think they wouldn't have any nice things by now.
Yeah, and you didn't have to wait long for the effects of such approach. 4:23 the fella showing the electron flying around the proton, which is a complete bulls#*t. Every secondary school student knows that.
@@piotrang8634 I'll bet he knows too. But this model works quite good for most of the basic chemistry.
@@ptitera - the model of flat Earth supported from below by four elephants would also work equally "quite good for most of the basic geography" 🤣
@@piotrang8634 Yes, and unless your measurements do not exceed about 30km in length you may freely use it (except of height measurements).
The thing is you have to know limitations of your model and when to switch to another one.
Keep in mind too that this lecture is intended for young audience. They are not ready to understand the physics of electron.
I would like to Very Respectfully remind Dr. P. Wothers, that the proper pronunciation of Nucleus is "Nuke-LEE-es". Both my wife & I, time & again, listened to your pronunciation of Nucleus (right after mentioning Potassium...) said, "Nu-Kee-les in the heart..."!! (chart of Electrons: 19, Neutrons: 20). Please notice that by no means I mean disrespect. In fact, I gave a thumb up. Thank you for giving all the youngsters interest in science.
Considering how old and prestigious is that lecture hall, I wonder how many other explosions have occurred there as a result of lectures and presentations.
I'm now curious to know the ratio of intended vs. unintended explosions :-)
@@theskett Ha! Great point!
@@3VILmonkey p!
One per semester per 100 students..taking chem. Things happen one goal for is no deaths no hospitalisation , a couple stiches is knda ok.
Deflagration encouraged, detonation slightly less so. Costs a lot in glassware and insurance premiums. :)
Fantastic presentation.
I had never seen the Potassium mirror demonstration before nor the baloons of different gasses.
Thank you.
Thank you very much for your lecture.
A few years ago l attended your seminar in CAMBRIDGE Summer Programmes. At that time I didn't understand well what the periodical table means. This lecture helps my understanding much better. From JAPAN.
Chemistry has always fascinated me, electrons, protons , neutrons. The lecture was very informative and entertaining, I will be looking forward to checking out more of your lectures. Thnx dr. Peter worthers. ✝️🙏
there is chemistry going on in the skin of the people in the mid-back row. "As we can all see, the constant heat of the spotlight slowly but surely draws the H2O out of their pores and evaporates it into the air as 'water vapor', quite brilliant really"
Cool experiments. Entertaining and educational. Thanks. Cheers from Canada.
I never knew that diamond was the best conductor of heat, thanks!
If my chem teacher was explaining things as well as Mr. Wothers, life would have turned out very differently for me, even without these lovely experiments.
One of the best science based channels on TH-cam.
That was really an AMAZING lecture ! Packed with information, history, and entertaining visual experiments. I really had a great time watching this. Thank you. 👍🏻👍🏻👍🏻
Thank you, Mr. Peter Wothers.
Always so inspiring chemistry from Peter W Thanks from Sweden.
Thank You Dr. Wothers
Excellent lecture. Best explanation of periodic table with real experiments to prove. And fun too!
Excellent way to spend an hour and a bit. I loved chemistry at school, and wish my 16 year old self had had the foresight to continue with it.
If mister Wothers was teaching at Prince Edwards Boys High in the early seventies, I would definitely be a Chemist today. Thank you Sir!
Fantastic video! More of these, please.
I was a professional chemist for many years (Ph.D.), and I've never seen that potassium mirror demonstration before. There's always something to learn from these lectures!
Thank you so much @The Royal Institution for this superb show,❤
Brilliant presentation. Impressed as an adult, I can only imagine how elated I’d have been, as a child, watching this, live in your lab. Good show!
im 12 and im in 7th grade and i had to watch all of this for homework. This is the one time homework was fun :(
Thumbs up! :)
Indiana USA.
An absolutely brilliant lecture, the lecturer has a great ability to hold your interest.
What an amazing professor!
Excellent presentation!
I expect that one could differentiate solid gold bars from tungsten containing gold bars by the different sonic responses.
What would Au’s frequency be, do you know?
That was great! Thank you.
I love ❤️ this guy and his lectures!
Fantastic presentation.
0:24 Order!!!!
That potassium mirror demonstration was awesome.
Lots of good practical demonstrations. A very entertaining lecture, this what get kids interested rather than some of the rather tame Christmas lectures of recent years. Brilliant.
What an amazing teacher he is.
Brilliant! Don’t remember much of this from when I did chemistry at school in the 80’s. Very informative.
The burning steel wool looks so fucking cool
been watching at 3/4 spped after a dube and loving science thumbs up!
Great lecture. Science as it should be accessible and fun.
So cool! I'm an old (retired) chemical engineer and I just learned about coulombic explosions from the sodium-water reaction!
Incredible! I haven't seen so clever man for a long time! He didn't have a look at some helping pieces of paper! It means only one-he really knows what he does! I'd fancy meeting that guy!
Best lecture ever!! Great presentation, really good presenter.
Love this presentation
This lecture is REMARKABLE!
Excellent lecture. Interesting and informative!
I learned a lot and had a lot of fun watching. Very good lecture.
8:33
A satisfying "Nucleus".
Use it to ignore all the instances of "nuculus".
thanks, he always ends with a bang
I learned a ton just now. Thank you so much 💓
Only 227 thumbs up..... this deserves so much more..
Should have explained a bit about how the orbitals and shells are structured, as this would lead to a better understanding of why elements react with each other. EG: Helium is stable because the S1 orbital is full - no need to try grab another electron from somewhere else...
This is a really fun and engaging presentation!
Great lecture. I am a chemist but have never known about the history of the periodic table. Super interesting
the end is fantastic 😊
I'm crying 😭 all the kids teachers must look like
Spent almost 1 and a half hour in a single sitting wonderful
fascinating . i was expecting to learn how to cope with my wife once a month. but this was even better
Very good presentation!
The Robin Williams of chemistry 👍
This is awesome. Lovely
A brilliant lecture!
I absolutely loved this
24:35 I'd have said that helium extinguished the flame because, at least locally, it prevented oxygen from keeping it burning... (If it literally "did nothing", the flame should've been unaffected, no?)
Yeah I caught the same thing... Lack of precision of speech, hopefully they know what he meant. I could imagine have questions as a kid after hearing the way he said that.
"How does it put it out if it does nothing?"
What it's doing is displacing oxygen...
Great lecture.
excellent lecture... excellent lecturer... thank you.
Excellent!
Terrific lectura indeed! I understand the periodic table at last… 35 years after I left school!
this was great, I learned so much.
I had a Mebus band version (2D version) and the Lanatide fit into the standard table. It was made in the 70's by a Sr Scientist Chemistry - G.E. as I recall. I got it and gave mine to the Chem teacher next door. I taught Technical Electronics. Never got a picture of it and is my lament since.
I am very much injoing this lecture.
I used to love teaching the Periodic Table.
brilliant! you made me a chemistry fan. why why whyyyy!!!?!?
