Great lecture! Science for everyone explained with simple & funny analogies. My timestamped bookmarks of lecture's first part in "mmss" format (mm=minutes, ss=seconds):
636 2.5% of Earth water is freshwater
845 water problem: 66% of water used (a small % of above 2.5%) is for food
1020 water stress world map evolution since 1950, to 1995 & 2025 prospects
1140 half of gasoline used in Sao Paulo is made from sugar cane
1215 why should we care? 70% of human body is water
1240 water introduction
1520 hydrogen bonding explained through Marcia' animation on the stage.
I agree, there is room to improve video's annotation for anyone with the skills and the willing to volunteer the required time. My annotations work for me when I use video player's scrollbar with the advantage of serendipitous discovery of side effect knowledge. I'm puzzled though why your interest in this topic is not reflected in your choice of vocabulary use.
thanx Ms Barbosa,..once again,you inspire!
Very inspiring Marcia Barbosa! Thank you very much for your passion and your work in so many fronts! Hugs from another Brazilian doing science in Canada :)
A most entertaining lecture!
Water is SO fasinateing.
Water memory too.
Hydrogen and Oxygen.
Two of the most explosive atoms in the universe.
Good old H2O.
Thanks from North West England UK 👍
what is the use of membrane distillation ?
we can get water by condensing directly and not using membrane and nanotubes, right?
I was there in the audience! I'm at 28:50.
You look like you're about to heckle...
...Terry White said, wanting the world to know their opinion on the matter.
It's fun to see yourself
Like when you're a kid and you see a CCTV display. Look I'm on TV! 😂
Thank you. Like the particles that hate water. :)
flirting and attraction, now I understood:)
Great talk. And she's dressed like she belongs on a an SNL skit. lol
It's amazing what a little water will do . ----------0
She's so cute!
I wanna see all the intros from these videos put together 🤣
she's sweet as heck. 'but' we need water now more than ever to power cars and electricity storage - hydrogen cars from hydrogen h2 from water, hydrolyzed by renewable energy like wind, sun etc. - and negative birth rates for a few (dozen) millennia :):)
