Physics is where real researchers are: They go behind ideas and concepts!
Physics is were real professors are: they “profess” ALL knowledge irrespective of their own expertise!

Padma Awards

Why are non-Indians and who don't live or contribute to India's development awarded the 'Padma" awards?

For example:

I understand Prof. Venki, Nobel Laurette, was also awarded a Padma.

No doubt they have contributed most to Science. No doubt they deserve the highest honors around the world. But why would an award instituted for the Indian citizens who have contributed to the development of arts, science etc in India be given to someone who did almost nothing to India? (They probably were not given a good chance in India, or didn't find the right intellectual mix that is required for such accomplishments - this is a different issue which again we Indians need to think about, especially in the Science sector.)

If inspiring the younger generation is a purpose to argue, then I only find inspiration to leave India and work abroad forever. :-\

The Mpemba Effect: Hotter is Faster

The whistle blows and the students start running in their tracks. It is a 500m running race. Unfortunately one of the students falls down tripped by his shoe lace. Without thoughts about the injuries, he quickly gets up, ties his shoe lace, only to find that his competitors have overtook him by a significant distance. With a new surging determination, he starts running. He ran with a speed that surpassed all his earlier feats. He wins!

One might have observed such scenarios commonly. The slower ones (or atleast the ones that we think will be slow) pick up the faster, be it in studies, competitions or in life. Water is no exception to this rule. It is common sense to expect hot water to cool slower than cool cold water. Hot water has lot of energy to lose to become cold, while cold water has relatively less energy to lose to become cold. Sounds perfect. But is it truly the case? Controlled experiments show that hot water cools faster than cold water! And what more? This trend continues beyond the crossover point as well!! Check out this article here.
