- Lecture Date: Tuesday, February 24, 2009. Water, H2O, is familiar to everyone - it shapes our bodies and our planet. But despite its abundance, water has remained a mystery, exhibiting many strange properties that are still not understood. Why does the liquid have an unusually large capacity to store heat? And why is it denser than ice? Now, using the intense X-ray beams from particle accelerators, investigations into water are leading to fundamental discoveries about the structure and arrangement of water molecules. This lecture will elucidate the many mysteries of water and discuss current studies that are revolutionizing the way we see and understand one of the most fundamental substances of life. Lecturer: Prof. Anders Nilsson, SLAC National Accelerator Laboratory.

Water 💦 and Air are life and life without them will be impossible 🙂😌😁 Assuming the water 💦 we are drinking and the Air we are breathing are safe and clean.
Great presentation!
Perhaps I could add that the interpretation of X-ray structure of "Td" geometry for water can be better explained with the computational results of electronic/vibrational coupling such as (Tx(t+e)).
Or (Exe) vibronic coupling.
Water denser in liquid state...water is diamagnetic which indicates its low magnetic permeability. Magnetic permeability is directly responsible for structural behaviour (e.g. heavyness or lightness). In case of water it is next to Bismuth, so very very low. It´s diamagnetic index is −0.91. That´s those 10% you are looking for in terms of structural expansion...
The benefits of water.
I would like to suggest that this is a "must see" video for anybody that has anything to do with the science (and continuing controversy) revolving around H2O polarity and hydrogen bonding. Along those lines, I suggest that they authors update the search terms so that this video is easier to find. I have been looking for something like this for over a year. I don't remember what string I put in to finally find this video, but it was not short or obvious. I think that if somebody types in "hydrogen bonding" or "H2O polarity" then this video should come up in the first ten. -- Just a suggestion --
couldn't agree more about this video's value. The presenter does a terrific job of clearly conveying the material without adding 'extra yokes to the batter.' I've bookmarked this for my reference and to send to others, but it's a shame more people (than 30k as of Jun 18) haven't seen. You may be right about the search terms or 'tags' but I'd also keep some onus on Alphabet's algorithms; their web services have a tendency to *especially* promote controversy or superficiality - and, I would say, not merely as a result of the race-to-the-bottom principle. Even cognizant of the company's broadest-ranging aims, it's still puzzling to me some of the personalized recommendations YT Red generates for me. Makes it hard to find quality content like this.
Oh well. Happy I came across this video when I did. Cheers.
Check out Polack fourth phase of water
This guys awesome 👍

Excellent.
Thank you for posting this video
Is there any other video(s) of this interest with moving pictures or clips? This is an interesting one.
There is a series of books by Masaru Emoto, the first book was a Gift and its called "The Hidden Messages in Water Its put out by ATRIA BOOKS
Thank you. 🙏
Water can keep us alive 😅 but at the same time can take your life and mine 😂 away.
I love it when foreign nerds think there's such a thing as a "dance restaurant".
what?
still, incredibly interesting work.
The diagram looks like a wedding reception much attended by younger/energetic people--who are energetic enough to fill the dance spaces.
66 anomalies of water...sounds like the title of a song
I got 66 anomalies, but I bet u ain't one
That is the biggest chalk board I've ever oh never mind
Ham Dog, give the guy the mic already.
When Ice is tetrahedral, Is it posible that liquid water is able to form icosahedral strucktures?
No, 20-sidedness is not possible
H2 Fuel Cells , that is the future beyond Battery electric cars.
water is made from silica dust on electric charge... imagine that
Weird how the water in ocean looks green from earth. But from space its blue
I learned most of this in high school... graduated in 1974... Whiskey Tango Foxtrot...???
Same here.... and I tried to explain how the level doesn't change as an ice cube melts in a glass of water , to some one here on you tube . They got back to me and said they tried it and agreed with me. Then they said ' but when the ice on top of the Arctic ice sheet melts, the water level will rise '. I gave up !
@@waynebow-gu7wr it would rise but it will have an affect on the planet. The earth has to warm up for it to even melt so..that increase heat alone will affect the weather and other things
In modern high schools we're only taught basic math and scientific principals that make good work sheets
1974? It wasn't experimentally shown until November, 2020 that water has two simultaneous structures in liquid phase. Do you know if they used high-speed X-ray spectroscopy to find this in the 1970s?
The audio really needs cleaning up.
toooooo quiet can hardly hear it volume on max !!!!!
i like it and enjoy the H2o
poor sound quality from audience questions.
and overall.
I always liked water:D
So you are hanging out with the disciples... at dinner after a long walk... and you reach across the dinner table to grab some flat bread when Peter grabs your hand, looks in your eyes and says: " But they deliberately forget that long ago by God’s word the heavens came into being and the earth was formed out of water and by water!" And you are like...."Thanks for that Pete!" No theory of planet formation has arisen yet....the universe is suffused with water and no-one is looking at water as the ciumping agent including these Slacers.
Nilsson hasn't figured out that H2O polarity is variable and hydrogen bonding is the mechanism that neutralizes polarity by way of completing the tetrahedron. So, the anomalies he has found are the result of polarity being activated in the jumble of the matrix under the surface as bonds are broken, temporarily reactivating polarity.
These PhD's are overly concerned with detalls and can't see this simple truth.
That made no sense.
Jealousy is a terrible habit...
James M - Can you explain the second sentence in your comment? (or, which comes to the same thing, rephrase/restate?) It's gotta be my own 'density', but I'm not sure I understand your meaning. Thanks !

Hi. I didn't see your question until just now. Thanks for the question. Yes, I can explain it. It is fully explained at this link:

I know what you mean!
Dihydrogen monoxide is so cool
diacetylmorphine rules
Calculating molecular mass while in reality dealing with permeability is really sad to look at...
Yikes. I just drank dihydrogen monoxide. What should I do ?
sandy moonstone your dead.
Drink an alchoholic beverage. That will help expel it from your body.
That's to bad everyone who drinks dihydongen monoxide dies eventually.
Stick your head between your knees and kiss your arse goodbye.
You need to drink a glass of water to wash it down..
terrible audio... couldn't hear nor understand anything
Great info, but the sould is awful!
I don’t know how I ended up here, but since I am... Guys entire speech revolves around the one word he can’t pronounce. Literally the only one he says Weird. U had one job.
I understood him just fine.
Give him a break. He's from Sveden.
Hydrogen should have been utilized over 100 years ago. But some rich ass stopped that.
Just terrible audio quality. I’m sure the talk was good but I can’t make out all the words.
Funny to hear water being referred to as strange.
You're 7 years older now so you may have realized already, but the more you learn about even the simplest things in our universe the more you learn that we know nearly nothing of their complexity. I'd argue that some of the most trivial things to the average person are the most beautiful to a trained eye.
water always finds its level, so the Eart is flat mr. "scientist".
You need rehab and what the hell is an Eart?
Rehab for sure, maybe this guy can take a flight to see our spherical earth. Damn idiots never leave the ground and say the earth is flat. Other idiots never leave the house and complain about the weather.
We only think levels are "flat" because we experience such a miniscule area of gravity. Water can be curved and still level, usually perpendicular to the ground but not always.
I’m thirsty now 😀💦💧🥃

He just BRILLIANT!!!!!!!!!! He thought of everything! 😂❤🙋🏼♀️🇬🇧
Is this ENTIRE video blurry or is it MY eyes? How annoying, considering how important the subject matter is!
These videos are 12 years old, and the digital cameras were not that good back then. Nothing is blurry, just very low resolution, and CZcams was limiting everything to low bandwidth. Our newer public lecture are now at least HD.
Hydrogen will never be economically cracked out of water.
