Throw out your physics books!

Physicists in France have discovered a liquid that "freezes" when it is heated.

This is really wild, a liquid that becomes solid when heated and goes back to a liquid when cooled.

Physics as we understand them now is still usefull, just not for everything. The universe is extremely complicated, and there will most likely be different Physics for different types of matter. There will most likely never be a "fit all, be all" type of physics.

We are still infants in this universe, and are just grasping the most simple of things. We have a long ass way to go. Hell, we don't even fully understand our own planet yet

Amazing, Great Find man! Im giving this to my professor

I wonder what the specific heat is to make that phase change?

I am taking Chemistry this year in high school. I'll take Physics next year. I wonder if that will be in next years Physics book.

Not for another couple years at least.

Yeah your probably right Evan.

Yes, but your teacher should say something about it at least when he gets to explaining phases.

The paper (M Plazanet et al. 2004 J. Chem. Phys 121 5031) has been accepted and published in a science journal, which is no small feat. It is now subject to peer review, which means that other scientists will try to reproduce the results using the exact same methodology. If the results are reproductible, the discovery is now science and will quickly get included in new editions of college textbooks. High school text books are another story.

My server class is using books from year 2000! lol.

Hilarious when they say, for servers your minimal CPU should be about 350Mhz. He he he

"'...workers confirmed that the cyclodextrine ring becomes distorted as it is heated up to close to the solidification temperature. The hydrogen bonds within the áCD break and the hydroxyl groups rotate towards the outside, which allows a network of bonds to form between the different molecules.''"

Sums it up nicely. :freak:

It's been 20 years since my biochemistry degree, yet I still understand this stuff! Looks like I'm not senile yet...
