I study Law at Nottingham but I really do love these videos and the information shown in them, though most of it is beyond me it at least allows me to ask my comrades in the science department the right kind of questions. Great video as ever Brady.
Those liquids sound amazing; You should do a periodic video on some of Pete's ionic liquids. The idea of a liquid that is less volatile than metal is mind blowing.
Allow me to add my congratulations to the rest on your promotion, Dr. Pete! Oh, and here's an idea: how about doing a Periodic Video on Ionic liquids: what they are, how they act, what differentiates them from melted salts, etc. etc.
Kindof, the ionic charge between the molecules is so great that this overcomes any atmospheric pressure changes. The charge is so big that it's simply held together too strongly to separate through evaporation.
at that school, Nottingham, the order goes up from lecturer, assistant prof. professor. PhD is a degree after your masters and gets you the title of doctor (small d) no matter what your job title at the school. the doctorate shows a level of education and professor shows a level of seniority.
I imagine it has something to do with the vapor pressure of the liquid being so incredibly low that the temperature just can't get high enough to create vapor under any sort of normal conditions. Solids have a vapor pressure where they begin to sublimate (turn to gas) faster than it can deposit (turn back to solid) and this basically boil away. Think dry ice. Except their pressures are also very low. Apparently these liquids have a vapor pressure even lower than all the normal solids.
The thing with time capsules now is that everything is so well recorded I doubt people will be able to find out anything from a capsule than they would in a book.
I'm not a material scientist, but I think, there is a certain probability for every liquid to lose molecules. Just think about definition of temperature. It is a description of the average velocity of molecules (or atoms). So it can happen, that they break away from the other molecules and evaporate. But I'm just guessing, would like to hear other opinions
the problem is a hdd has error less storage up to 5 years after that it degrades. tapes can go up to 20 years. so they will need to use some special nand like sdd. but its still a good idea. (but i don't think that sata will still be copper in 100 years)
So those ionic bonds prevent the molecules from gaining enough kinetic energy to escape and increase the vapour pressure above the liquid, so it will always be lower than atmospheric pressure, is that right?
They should get nice little foam cradles or something to more securely hold each item.... as is they'll probably get knocked around quite a bit as it gets buried. Unless this is all for show and it's not actually going in the ground.
They will break down if you heated them up to an enormous temperature, but they wont evaporate under low atmospheric pressure (unlike all 'normal' liquids) due to the ionic bonding between the molecules. Water for example would evaporate under low pressure, these liquids do not.
you dont know what old problems new discoveries can solve until you discover them.. it is rare that a new piece of medical technology or practice is created on purpose. purposeful applications come from accidental discoveries.
This video begs the question "what is an ionic liquid?" He mentioned it won't evaporate in a vacuum but didn't explain why. It would be nice to see a follow up video about ionic liquids to go into more detail.
sadly i doubt someone can read read the data in 100Y. But i like the idea too. At least i would add the capsule videos as analog Film. I guess the will be able to figure out how to play that.
the magnetic data on the platters will just go away after ~100 Jrs. They should rather store it on a ssd with hard-written ("engraving" the data directly onto the silicon) rom chips.
Can somebody explain the difference between the titles of professor, lecturer, doctor etc? Don't you become a doctor once you have a PhD? So when can you become a professor?
The reason that ionic liquids have such low volatility is because of the strength of the ionic bonds? I wouldn't really go as far as to calling that "surely a fit answer", to be honest! haha. That's like saying that water puts out fires because it's wet! But anyway, no problem, thanks again. ;)
In modern usage "begs the question" and "raises the question" can be used interchangeably.- (from The American Heritage Guide to Contemporary Usage and Style) "... the expression is also used to mean simply “to raise the question.” These looser meanings have long been condemned by usage commentators as incorrect or sloppy...But we can easily substitute evade the question or even raise the question, and the sentence will be perfectly clear, even though it will violate the traditional usage rule."
tapes are still used in servers to backup data. i have no idea for an ssd. it will probably be affected by the size of the process the ssd was made on. so if you have a SingleLevelCell 190nm ssd than it might hold iets data longer than MultiLC at 32 nm. also other types of ssd than nand/nor cell could be better. here is a link for newest exotic memory. link: extremetech/com/extreme/160928-five-dimensional-glass-memory-can-store-360tb-per-disc-rugged-enough-to-outlive-the-human-race
Thanks. I don't want to sound ungrateful, but that is not really much of an answer! I knew that before I asked the question. I want to know how it works, exactly. Cheers.
Shouldn't they protect these glass vials against breaking? Because if somebody finds that capsule in the future they definitely won't be supersafe with it.
so you're telling that making energy and new manufacturing methods cheaper and more sustainable is not contributing to solving problems like hunger and access to clean water? really?
It's a beautiful thing to see a man so passionate about his work and his students.

Don't cut yourself out of these videos, Brady! You're what make them fun and informal.
"mine won't" Love it.
Congratulations to Pete.

I love how Brady continues to impress me over and over.

Yes. If you try to imagine how slowly solids evaporate at room temperature those liquids evaporate even slower.
I imagine it has something to do with the vapor pressure of the liquid being so incredibly low that the temperature just can't get high enough to create vapor under any sort of normal conditions. Solids have a vapor pressure where they begin to sublimate (turn to gas) faster than it can deposit (turn back to solid) and this basically boil away. Think dry ice. Except their pressures are also very low. Apparently these liquids have a vapor pressure even lower than all the normal solids.
A hard disk containing all of these videos from every channel (Sixty Symbols, periodic videos, etc) should go in too!
A license to profess... You deserve it Pete, congratulations!
Well said! :) great speech and sentiment!
The thing with time capsules now is that everything is so well recorded I doubt people will be able to find out anything from a capsule than they would in a book.
Money, Power, Control, Influence for their own sake, do not not necessarily constitute progress.
Progress is defined differently by different people.
Congratulations on your promotions, Professor Licence!
Congrats to Pete for becoming a Professor!
Congratulations Professor!

I like this guy :)

Do I understand his implication correctly: even the glass ampules that hold the ionic liquids will decay/evaporate/dissolve before the liquid?
So those ionic bonds prevent the molecules from gaining enough kinetic energy to escape and increase the vapour pressure above the liquid, so it will always be lower than atmospheric pressure, is that right?
They should get nice little foam cradles or something to more securely hold each item.... as is they'll probably get knocked around quite a bit as it gets buried.
Unless this is all for show and it's not actually going in the ground.
Unfortunately, Prof. Poliakoff did not put it on his head. At least, on the video.
I'm sad about that, now.
Yeah, good on you Pete!
Or Prof. Licence, of course!
What a great speaker!
This guy just reminds me of the Potassium in the water experiment. "Very satisfying reaction!"
They will break down if you heated them up to an enormous temperature, but they wont evaporate under low atmospheric pressure (unlike all 'normal' liquids) due to the ionic bonding between the molecules. Water for example would evaporate under low pressure, these liquids do not.
Agreed. Are they viscous? Are they heavy?
You might find the Voynich Manuscript interesting, if you haven't already heard of it.
you dont know what old problems new discoveries can solve until you discover them.. it is rare that a new piece of medical technology or practice is created on purpose. purposeful applications come from accidental discoveries.
Are these ionic liquids a (cheap) replacement for platinum in fuel cells?
In the snapshot of the video before you open it it looks like he is putting a joint in the time capsule
I'm speaking without really knowing, but I guess them being ionic itself would give them a lot more internal cohesion.
would a video about pete's professor appointment not be in place?
Congrats on the Professorship
Put a penci and tape in there!
Since graphene has so many promising properties and it's being researched on everywhere nowadays
Congratulations on your new title professor Pete ;-)
Will they evaporate if you boil them?
What gives those ionic liquids such a low volatility?
This video begs the question "what is an ionic liquid?" He mentioned it won't evaporate in a vacuum but didn't explain why. It would be nice to see a follow up video about ionic liquids to go into more detail.
Could you tell us what the liquids are? I saw EtOSO3 on one of the bottles, but I doubt that's Ethoxy Sulfite.
Never knew there were ionic liquids, my teacher always taught us that ionic compounds were ALWAYS solid.
The ionic bonding between the molecules/atoms
Isn't exactly that the meaning of evaporation? That a few molecules have enough energy (temperature) to fly around in the air as a gas?
the capsules in the capsule. All out lived by the liquid within.
High strength of ionic bonds?
Who wants to bet that some as yet unforeseen chemical process results in one or both of those samples turning solid?
Wow, this was really surprisingly interesting!
Everything evaporates at room temperature? Really everything?
sadly i doubt someone can read read the data in 100Y. But i like the idea too.
At least i would add the capsule videos as analog Film. I guess the will be able to figure out how to play that.
Going to put the videos in there too Brady?
That is correct
Sorry, I should have said: I agree, I would like to know more about this because I haven't heard of it.
OK, cheers.
Just because it breaks away does not mean it will evaporate.
Brady make a video about Ionic liquid PLESE. thx
what a passion and love for science! I love it! :D
Those things will out last the time capsule. Wow.
the magnetic data on the platters will just go away after ~100 Jrs.
They should rather store it on a ssd with hard-written ("engraving" the data directly onto the silicon) rom chips.
Did anyone else think he was holding a joint for a second in the thumbnail? lol
Hello Pete
it were. no school?
Pete looks formal in this video. Nevertheless, loved it
Can somebody explain the difference between the titles of professor, lecturer, doctor etc? Don't you become a doctor once you have a PhD? So when can you become a professor?
the power of friendship!
I didn't know that license/licence was one of those words that was spelled differently. My mistake, at least I learned something.

Nice Orwell reference :)
The music for this sounds like the Brookside theme.

the fact that they are made solely of ions
Whatever you do, don't shake them.
Nice intro Brady. XD
Thanks. I don't want to sound ungrateful, but that is not really much of an answer! I knew that before I asked the question. I want to know how it works, exactly. Cheers.
"Into room 101" Is that a fallout reference I detect?
They are ionic, that's it, the fact that they are ionic.
Err, this video needs a high pass filter, because my subwoofer is freaking out.
Wont last 100 years though :/ BUT! There are DVDs mad of stone that will last for 10.000 years! AND store about 20 GB/Disk :) So it is possible! :D
cool cool cool
should be
So you could say he has a ... Professor Licence
Shouldn't they protect these glass vials against breaking? Because if somebody finds that capsule in the future they definitely won't be supersafe with it.
I suppose the latter
That's a can of worms you probably don't want to open up on an British-English-speaking video...
so you're telling that making energy and new manufacturing methods cheaper and more sustainable is not contributing to solving problems like hunger and access to clean water? really?
Pete would kick your ass if you said that to his face. No, he means even if opened, they won't ever evaporate, ever.
wow you're a professor, I thought you were a disaffected technician ;)
I see no argument against progress. All you said could have also been said during the 19th century.
I thought he was going to put some wire in it!
I can't be the only one who thought the thumbnail was weed..
Who else clicked it because it looked like a spliff?
made for martin poliakov's head
I lol'd
Put some dry ice in there, just for shits & giggles.
Pete License? Don't you mean shiny wire guy? :)
go green chemistry
