“This model is difficult to rotate because it squeaks.” Professor Poliakoff may be the best deadpan comic on KZbin.

I was NOT expecting that. I had to pause the video to laugh.

[@StarkRG]

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.

[@drskelebone]

@ DITTO!

[@cgpirre]

I would pay big money for an 'Airplane! remake with the Professor in Leslie Nielsen's role.

[@tsalVlog]

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..."

[@bohanxu6125]

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

1. RATS CANNOT BE SICK 2. PHOSPHINE MODEL DOES NOT ROTATE EASILY BECAUSE IT SQUEAKS

Rats squeak, therefor the Phosphine model contains rats.

[@74KU]

Why would you wish phossy jaw on anyone?

[@chrisofnottingham]

TLDR: There might be life on Venus but it isn't rats

[@Reth_Hard]

But did they look inside Venus's sewers? I'm not sure about that...

[@hrperformance]

🤣 Definitely not rats!

[@SigEpBlue]

Could be pegasi, especially if they're living in the clouds.

[@philojudaeusofalexandria9556]

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.

[@christopherflowers2327]

Penguins, not rats!

[@adamhunter1223]

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.

[@Punnery]

Yes! It's such a relief.

[@ramiro6501]

He is a real scientist!

[@Pekkhum]

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.

[@baltakatei]

Also: RAT FACTS

[@pattheplanter]

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.

[@TATASPIDER]

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.

[@silmarian]

I'm really glad to hear the Professor on this!

[@mid7699]

What about Beirut explosion reaction?

[@pondersong5525]

Another takeaway is that the Professor is getting better at filming himself during the pandemic.

[@claycross840]

"If you've learned nothing else! from the phosphine on venus, its the fact that, rats, cannot be sick."

[@fejimush]

Thank you Professor, I could listen to you talk about chemistry all day. Be well.

[@robertfletcher3421]

What a level headed explanation and at the same time we learned something about rats.

[@srowley85]

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.

[@kjgoebel7098]

"Let's get back to Venus." The professor is an alien, confirmed!

[@luciengrondin5802]

That was a very convoluted way of teaching us a factoid about rats.

[@Coastfog]

Rats? All I took away from this video is that Phosphine squeaks.

[@rodchallis8031]

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!

[@douro20]

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.

[@dukemandu]

Interesting stuff, professor. I'm glad you chimed in on this recent discovery.

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

[@DayaCIDfan]

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!

[@lohphat]

“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.”

[@Aphelia.]

Thanks I was confused as a foreign

[@pizdarus]

Both terms are used in the UK fairly often.

[@Chizzy941]

In the UK it's both a noun and an adjective

[@lohphat]

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.

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.

My dad was born in January of '45 and is still working on our family farm, driving trucks, tractors and walking the fields without any cane or walker. Poliakoff is only 73.
