“This model is difficult to rotate because it squeaks.” Professor Poliakoff may be the best deadpan comic on UA-cam.
I was NOT expecting that. I had to pause the video to laugh.
So, if I'm understanding him correctly, they used telescopes to detect rotating phosphine molecules on Venus by the tiny squeaks they emit while rotating, and it's a possible sign of life because it would attract stray dogs.
@ DITTO!
I would pay big money for an 'Airplane! remake with the Professor in Leslie Nielsen's role.
omg. I had to pause the video at one point. I came back, read this comment since it was at the top, then unpaused it. I had paused it right before he said, "I should say, this model is..."
1. RATS CANNOT BE SICK
2. PHOSPHINE MODEL DOES NOT ROTATE EASILY BECAUSE IT SQUEAKS
3. WHEN YOU POKE THE MUD AT THE BOTTOM BUBBLES OF GAS COME OUT
Rats squeak, therefor the Phosphine model contains rats.
Guess I no longer have to watch the video. All the information is right here.
@@Wourghk That must have been a skaven, not a rat.
"Yes. The -Mouse- Rat Problem. This week 'The World Around Us' looks at the growing social phenomenon of -Mice- Rats and Men. What makes a man want to be a -mouse- rat." ~ _Monty Python,_ s1e2
8:25 "I'm not an atmospheric chemist, so I'm not going to tell you now some brilliant explanation, because I don't know one. BUT I KNOW ENOUGH ABOUT CHEMISTRY, TO RESERVE MY JUDGEMENT"
man...only if more people are like that, our social discourse would be so much better
Hope he has been doing well. He better stick around for another 20+ years
Indeed, would be great loss to education and science.
Here's to many content and long years
Dr. Poliakoff is the Carl Sagan of chemistry
@@FrEdminson
I don't want to scare you or anything, but the majority of people die eventually, especially when they are old...
Recently, Dr Wade died. The inventor of Wade's rule.
@@louistournas120 2014. I wouldnt call that recently.
I wish the Professor a long , healthy and phosphorus life...
He's contributed a lot; not only to the scientific community, but also to the rest of us students, amateurs and curious people on UA-cam...
Why would you wish phossy jaw on anyone?
Other (esp popsci) channels: "In today's episode of Clickbait!: Here's *cool thing* it totally means *imminent asteroid impact, extraterrestrial life, whatever* Now for some wild speculation! Like, comment and subscribe!"
The professor: Here's a general overview of what's being discussed, here's some context to put things in perspective, this is what I find interesting about it. However, it's important to be skeptical about things like this and this is not my field of expertise so I'm not going to speculate.
Yes! It's such a relief.
He is a real scientist!
There are some very popular Doctors (medical and otherwise) who could stand to be reminded that they are not experts outside their field or specialty. By just having a doctorate your statements gain a lot of weight and you can do a lot of harm when you speak outside of your knowledge and then get quoted out of context.
Also: RAT FACTS
But he does give the opinion that someone is likely to come up with a non-life process to produce phosphine, due to his knowledge of chemistry. Complicated stuff chemistry. The Universe is still surprising us regularly.
"Rats cannot vomit." You learn something new everyday.
Fun fact! Neither can horses
@@joshme3659 what about giraffes?
TLDR: There might be life on Venus but it isn't rats
But did they look inside Venus's sewers?
I'm not sure about that...
🤣 Definitely not rats!
Could be pegasi, especially if they're living in the clouds.
Plot twist: They are hyper-intelligent rats that are pumping phosphine into the upper atmosphere so that humans won't go looking for rats on Venus.
Penguins, not rats!
Another takeaway is that the Professor is getting better at filming himself during the pandemic.
I'm really glad to hear the Professor on this!
What about Beirut explosion reaction?
I am 50 years old and have been for almost 2 years studying chemistry and physics on my own just because I love them.
You do the best videos! I enjoy them and learn so much as well. Thank you for doing these wonderful videos.
I’m one of the few who actually did chemistry with phosphine. We use to use it to make LiiPH2 by reacting it with n-butyl lithium. This reaction was always carried out on weekends, so if there was any problem there weren’t as many people to evacuate from the lab building.
Thank you Professor, I could listen to you talk about chemistry all day. Be well.
"If you've learned nothing else! from the phosphine on venus, its the fact that, rats, cannot be sick."
What a level headed explanation and at the same time we learned something about rats.
In grain silos they often use aluminium phosphide pellets as a fumigant. It's usually sourced from China and it comes in tightly sealed pull-tab cans since the compound will release phosphine gas upon atmospheric contact. Every fall when the silos are empty they will put the cans down and open them then seal up the silos for several weeks. Afterwards they will start up the drying fans for several hours to clear up any residual gases.
Wow, I always hate when I get parasitic turtles on my t-shirts. Now I know how to get rid of them!
Excellent background on Phosphine and what it may mean in terms of life on Venus. Thanks!
we're owl exterminators!
Never cut off all that hair, the channel wouldn't be the same. :-)
This hair is the purest metal.
It was all trimmed short when we first started sheltering in place.
He does have to occasionally trim it a little, otherwise Professor would eventually look like a character from _Naked Gun 33 1/3: The Final Insult._
His hair must be fire proof.
Da Prof with da 'Fro, bro. Rulin' da (fume) hood since Periodic Videos started!
"Let's get back to Venus." The professor is an alien, confirmed!
1:55 Oof. P2H4 error in vid (as PH2H4)
Yeah I thought I saw some weird video issues, thanks for putting it into words that I can now learn about ;)
I was looking for a comment like this to upvote :)
Unfortunately Brady's videos have dropped considerably in quality since the Prof. Moriarty incident and they never recovered.
@@hobbygaertner420 What incident?
Ironically, the video description contains the sentence "Apologies for the P2H4 typo, which should read PH2H4".
Prof. Poliakoff has the greatest hair known to man.
Also, yeah, Venus.
That was a very convoluted way of teaching us a factoid about rats.
Rats? All I took away from this video is that Phosphine squeaks.
Seeing a new Periodic Videos, video in my sub feed maKes me so happy i can't wait to watch it, all these years and you all held my full attention and interest, keep em comin.
Prof. Poliakoff, been watching you since childhood. Once, when I was 16 years old, a representative from University of Nottingham came to my school to inform us about the university and I asked him if he knew a prof. Poliakoff from the Chemistry department haha.
Today, I am in university myself and I realize that there's no chance someone people know every faculty like they did in my tiny school. How childish of me! Hahaha, you were one of the 3 reasons why I ended up in Chemical Engineering and you have no idea how much I love every second of it.
Thanks for impacting me at that age, I wish you many more years of health. Lots of love!
I never thought the man who pioneered lockdown hair in normal times could exceed himself, but it appears he has.
This has been one of the most helpful videos, for me, in understanding the phosphine on Venus reports.
It's amazing how you can give the feeling of both a Manhattan project's physicist and a grand-father with fresh baked cookies at the same time, Sir.
I've been waiting for Periodic Videos to explain all this to me! Thank you!
Finally!!! a real knowledgable person talks about it! thanks Profr!
This man would be a fantastic teacher, lecturer at any college anywhere.
Interesting stuff, professor. I'm glad you chimed in on this recent discovery.
“Sick” in common UK usage means “vomit” (noun) as opposed to “ill” (adjective) which is the common US usage. E.g. UK: “Watch your step! There’s a pool of sick (vomit).” vs US: “I’m feeling sick (unwell), I’m staying home.”
Thanks I was confused as a foreign
Both terms are used in the UK fairly often.
In the UK it's both a noun and an adjective
libjet True but more often sick refers to vomit, “I feel ill” instead of “I feel sick” is more common when feeling unwell (at least in the greater London area).
Your mileage may vary.
Thanks
Easy to follow without being condescending or elementary. Great vid! I'll look into this channel, subbed.
Sir, I don't know why haven't I searched such an amazing channel before, amazing knowledge hope you will be with us for more than 25 years
I remember as a child hearing the story of will-o'-the-wisp, and wondering why it couldn't be seen today, I spent many a hour across the Trent from you night fishing a pond that had a large marsh which bubbled foul-smelling gases, but not I or anyone I knew or talked to ever seen them spontaneously combust.
Great to hear the professor’s say on this matter!!
So glad to see the prof doing well!
It is A Blessing to know Your knowledge, time and effort keep uploading Thks
I cannot express how grateful I am to have you around helping share all the knowledge you've accumulated.
Now if we could only get others to share too.. just as selflessly.
Thank you professor. I have appreciated every single video from this channel.
I love this channel. I always learn more than what I came for.
The supernerd me love seeing these videos!
why do you hunt adams?
So is mine. Also, please do not hunt me.
This was the most informative with a bucket full of fun facts...plus the end was hysterical!
I am totally entranced. You are an amazing lecturer!
Doing great olderester. This was explained much better this time around. Keep it up, mate.👌👍
Sir, am in love with your explanation and story board, hats off to you ...!
amazing work he's spreading knowledge even at such an age where people are not able even to walk, he's just trembling but lovely person great dedication love you sir
Fantastic! And I'm sure many people will remember more because of the neat facts at the end
The professor's hair is looking particularly luxuriant today ...
Best explanation I've heard of the ph3/venus.
I really enjoy the professors et als., videos. I’m just a regular guy ,& find most of the subject matter fascinating & enlightening . Cheers!
I always learn from the professor. Today i learned that the professor's look are becoming very fashionable among many corona lockdown guys.
Excellent video, Professor.
This channel is old as youtube and it's still popular
This is huge achivment
Clicked for take on the whole Venus debacle, stated for facts about rats, rat poison, uses of the found chemicals, etc. Wonderful video. ❤️
Absolutely fascinating video, full of interesting information.
Thank you again for another wonderful video.
Excellent, thank you for this explanation.
Yeah, I remember in pharmacology the lecturer discussed animal models of disease, and I recall the ferret was used as the model animal for vomiting because it was the smallest animal capable of vomiting. Not sure if that is wholly true, or maybe it's the smallest practical animal for use in such tests, but its a bit of trivia that stayed with me.
YESSSS, I LOVE Your Channel @Periodic Videos
Every time I see your video, I learn something new
Another excellent upload. Thank you Professor.
I appreciate that you post videos “periodically”
Check out @bullaki for a detailed explanation on the recent Venus phosphine discovery.
Great video as always professor 👍
Sir Martyn you are a treasure! Thank you for teaching me.
I focus more on astronomy/cosmology, but it was interesting to hear a chemist's perspective on this
I love your sense of humor professor.😊
Glad to see the prof again. Great man!
Absolute lad, saw him at a lecture! He's great.
I always look forward to a new periodic vid. :D
Really glad to hear from professor 😊 really helpful information 👍♥️
Rats not having the vomiting mechanism is really important in the field of toxicology and allows for easy administration of substances for understanding their oral pharmacology. Really helpful to know that it is an antimony additive that triggers the vomiting sensation in other species. Keep well all!
Brady : uploads a new video
Me : let the video marathon begin
Awesome information thanks a lot
At 05:46 the internet was won!
"I should say this model is difficult to rotate because it squeaks."
"Squeak"
I bowed my head in appreciation... well it was something, my eye's were tearing up 😂🤣
Liked the video before I pressed skip, now that's rare. Nice one professor!
Albert Einstein of Chemistry World and Also great UA-camr.
Thanks Prof!! HOPE YOU ALL THE BEST AND KEEP HEALTHY!!
If someone puts hate comment on here, that guy who posted it will be hated.
"Treat others as you would like others to treat you"
I'm just glad in this world filled with trash people, that there's just some wholesome old guy with some crazy hair that wants to help the world and teach people. I love you old science man.
My homeland pretty much was made of marches and forests, before irrigation was a thing, now it's mostly forests - 56% of territory and growing.
Those marsh lights here are called "māņugunis", which could be translated as "deceiving lights".
Thanks for the video, Professor.
Best regards from the 🇺🇸 professor. Thank you for making science amazing.
my chemistry teacher was demonstrating reaction between white P and NaOH, but the reaction was rather vigorous and we all had to evacuate the chemistry department!
P4 + 3NaOH + 3H2O = PH3 + 3NaH2PO2
Found this channel from school, stayed because of how interesting it is.
The Professor is hilarious 😂 Incredible educational content as usual.
I hold this gentleman's literatures and video publishing's on the highest upmost reguards.
What a treasure this man is! Thank you!
Thank you, Professor!
Nice conclusion.
Thank you for the video
How much fun in science video! Prof is legend!
This is a nice episode I like it
Superb 👌thanks prof
Im really excited about this
I have video suggestion. In my chemistry class my teacher talked about Bhopal Disaster and I found it very interesting (and sad at the same time). A video about this tragedy and its chemistry would be very informative and nice. Thanks!
Ohh yea, i saw a video about it and it was absolutely horrific….
This is how you always proceed when you think you may have found alien life. First, you eliminate all other possible explanations. Then you timidly say "it may or may not be alien life".
Professor, You are the kind of a man who deserves maximum honor and respect. I wish I become like you sometimes :D
What a great video
Brilliant video - always love the chemistry knowledge, but the prof's hair and the rat info / jokes were most, most awesome too!!
That ending was amazing
