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.

I’m not a big fan of what the hospital euphemistically calls “cardio rehab” (hint: “exercise”), but I bought a bicycle and have been cycling along a nearby river, the Nakagawa. In fact, I just got back.
I can’t describe how much more fun it is, and how much quicker time goes by than it does on my indoor exercise bike (which is almost as boring as a treadmill).
Today I increased my distance and went on to the “second bridge” which is near Aoto. It really gets green over there. There’s a big sports field, and also a couple of small boat piers.
I actually left my house intending to go shopping, and then go for a bike ride in the late afternoon, when it got a bit cooler. But I found myself drawn to the river.
Also, I am definitely increasing strength. A somewhat daunting hill I had been stopping and walking up I took today with ease.
I can’t believe I’m saying it, but I’m actually looking forward to my cycling trips.
The purple one almost looks extraterrestrial.
While cycling just before along the Nakagawa, there were several jet skis and speed boats out.
