Why does hot water freeze faster than cold water?

If you have nothing better to think about today, how about trying to solve this old scientific puzzle?

“Why does hot water freeze faster than cold water?”

There is a £1000 pound prize for the best answer:

It seems a simple enough question – yet it has baffled natural philosphers for at least 2,300 years.

  • Aristotle agonized over it fruitlessly in the fourth century BC
  • Descartes was defeated by it in the 17th century AD
  • Even perplexed 20th and 21st century scientists and intellectuals have swarmed over it without result

Now the Royal Society of Chemistry is offering £1000 to the person or team producing the best and most creative explanation of the phenomenon, known today as The Mpemba Effect.

Space, the final frontier (From NASA TV)

Check out:


William Shatner, the actor who played Captain James T. Kirk on the original Star Trek television series, provided a special message to the crew of space shuttle Discovery during the 3:23 a.m. EST wakeup call on Mon., Mar. 7. As Alexander Courage’s “Star Trek” theme song played underneath, Shatner replaced the original television introduction with, “Space, the final frontier. These have been the voyages of the Space Shuttle Discovery. Her 30 year mission: To seek out new science. To build new outposts. To bring nations together on the final frontier. To boldly go, and do, what no spacecraft has done before.” 

The “Theme from Star Trek” received the second most votes in a public contest from a Top 40 list for NASA’s Song Contest. Shatner recorded the custom introduction for Discovery’s final voyage — its 39th flight and 13th to the International Space Station.

The one year anniversary of “climategate”

What’s amazing about “Climategate” is that even though all it revealed were a few scientists acting petty and one or two minor bad actors, groups who simply do not want to believe in climate change or its causes for political or religious reasons continue to bandy it about as though it was some sort of “smoking gun.”

Even though the sum total of so-called “climategate” did not actually refute one iota of the overwhelming scientific consensus regarding the existence and causes of global climate change, certain political groups, like the Tea Party, seem to take some sort of arrogant pride in their professed ignorance about what is happening to the environment and try to leverage “climategate” as some sort of political icon.
It’s as though these people believe environmental science depends on whether you are conservative or liberal or whether you believe in the bible or not. They remind me of creationists. Or the people who once voted that pi equals exactly 3.

These people are not interested in actual scientific evidence at all. They have reached their conclusion based on their political or religious philosophy and that’s that for them.

Here’s an interesting read:

“In fact, nothing in the stolen e-mails or computer code undermines in any way the scientific consensus—which exists among scientific publications as well as scientists—that climate change is happening and humans are the cause.”
