Going back 50 years old high school physics, I think it's due to the direction that heat travels - cold to hot, hence at zero, heat is travelling from minus to zero and hence ice is melting.

A lot of theory has changed since my days were spent learning defunct information so they may have a newer explanation now.

Well no physicists here so I went to google and found I was wrong. Heat travels from hot to cold, so my explanation doesn't work, but the theory does. Over to the brains trust

If you think of two 'boxes' of gas. One is hot, one is cold.

In the hot one, the particles are moving faster than they are in the cold one.

If you put the two boxes together and remove the sides so they can mix then the faster particles will flow into the 'cold' box faster than the slower particles from the 'cold' box will flow into the 'hot' one. If you measure the two boxes every so often, you'll notice that the average speed of particles in the 'hot' box goes down (because it's lost some fast ones from itself and gained some slow ones from the 'cold' box) and the average speed of the particles in the 'cold' box goes up (because it's gained fast ones from the 'hot' box and lost some slow ones from itself).

Speed of the molecules is how you work out the temperature, so you can see that the 'cold' one gets faster (ie hotter), and the 'hot' one gets slower (ie cooler). Heat flows from hot to cold...

crystallization of pure liquids usually begins at a lower temperature than the melting point, due to high activation energy of homogeneous nucleation. Freezing does not start until the temperature is low enough to provide enough energy to form stable nuclei. The melting point of water at 1 atmosphere of pressure is very close to 0 C, and in the presence of nucleating substances the freezing point of water is close to the melting point, but in the absence of nucleators water can super cool to 40 C before freezing.

The total cost of heart disease in the US in just 2008 was estimated at $300 billion.

the World Health Organization has estimated that ending world hunger would cost approximately $195 billion.

Keanu Reeves made $114m for the first Matrix movie. He gave $100m of that away to the SFX crew.

Overall he has made $260m from just the trilogy.

The united states is the only country in the world where more men are raped every year than women.

Because of their very large prison population and the prison rape culture that is celebrated in popular culture. Prison rape in Australia rising for the same reason - popular culture, and American culture in particular.

In the movie 'The Godfather' the soldiers are shown kissing the Don's ring a la papal devotion. This was a literary invention by Puzo, faithfully filmed by Coppola. After the popularity of the film, the tradition of 'kissing the ring' gradually arose in the mafia.

They already have a border fortification system built to stop Saddams' tank battalions from invading too. That's if Saddams' tanks were well maintained enough to get near the border.... So this is just updating their border fortifications from a conventional warfare threat to counter the new asymmetrical warfare threat.

Saudi Arabia also has constructed their own security wall inside Yemen to stop terrorists from crossing and killing their citizens. Internationally this goes unreported and unremarked upon. But when Israel did the same thing on a small scale only then because it is The Joooos that it is apparently a bad thing.
 
The Andamanese are believed to be descended from the migrations which, about 60,000 years ago, brought the first modern humans out of Africa to the Andaman Islands.

Besides the aboriginal people of Tasmania, the Andamanese were the only people who in the nineteenth century knew no method of making fire.

Not quite the same thing, the Saudi wall doesn't cut communities in half or stop people from getting to work or prevent people from bringing in basic necessities like food and construction materials. I believe in a strong and safe Israel and maybe they needed the wall, I know enough about it to know I don't know enough to make a comment on it's merits vs it's costs but I do know it's a lot more serious a deal than a wall across barren desert. The wall in Israel also has much broader political implications for the region and whether you think they are trumped up cynical claims to gain arab sympathy or genuine issues they have a much broader impact and are therefore worthy of discussion on the media.
