Israeli Scientists Freeze Water By Warming It

ccktech writes "As reported by NPR and Chemistry world, the journal Science has a paper by David Ehre, Etay Lavert, Meir Lahav, and Igor Lubomirsky [note: abstract online; payment required to read the full paper] of Israel's Weizmann Institute, who have figured out a way to freeze pure water by warming it up. The trick is that pure water has different freezing points depending on the electrical charge of the surface it resides on. They found out that a negatively charged surface causes water to freeze at a lower temperature than a positively charged surface. By putting water on the pyroelectric material Lithium Tantalate, which has a negative charge when cooler but a positive change when warmer; water would remain a liquid down to -17 degrees C., and then freeze when the substrate and water were warmed up and the charge changed to positive, where water freezes at -7 degrees C."

    I was addressing the AC parent, which was not only leaning towards hate speech, but also got a worrisome +4.

    You're right. But the world has a lot of excellent reasons to be pissed off with Israel these days. I don't call it hate speech so much as, "Great. Those genocidal, media-owning psychopaths are pumping themselves up again," speech.

    Anti-Semitic? No. Anti-Israeli? Hell, yes! -And it may be nothing, tagging a scientific discovery with the "Israeli Scientist" label, but it's that camel's back thing. After enough vile awfulness, (a WALL around an entire society using false flag bombings as an excuse for a land-grab? Black market organ harvesting? Using guilt to manipulate the world reaction to clearly psychopathic acts? For goodness sake!), every little spot is going to cause a reaction.

    Sorry if that upsets you. Israel == Evil.

    It seems to me we're not particularly good at black-market organ harvesting, considering the bunch of Israelis lying around waiting for transplants.

    Evil sells to the highest bidder and psychopathic governments are perfectly happy to abuse their own citizens as well as everybody else. But you know that. Denial is pathetic and you can only fool yourself. Others can and will see despite all tactics to the contrary. And deep down, you know that too.

    Anyway, if you are true to your anti-Israeli cause, I'd recommend making sure you don't use any Israeli products. That includes, of course, intellectual-products, such as Intel Core2 chips, various medicines, economy models, and so forth.

    It's not a moral/logical problem hindered by idiotic semantics. It's about applying economic pressure to a criminal state. Anybody interested in boycotting Israeli goods, it's easy to do. . .

    Check the barcode/UPC symbol. If it's made in Israel, the first three digits are "7 29". Here's a visual.

    Bye now, apologist. You should know better. Shame on you.
