Nature is a better Physicist!
This is the line quoted by my teacher of Heat and Mass Transfer Prof. P M V Subbarao at i i t delhi in today's lecture.
The example he has given is of Dianosaurs. Whenever you see any dianosaur image many of them have fins from nose to tail. Yes! You guessed it right. It has lot of physics to do with. The survival of any species depends on its adaptation to the nature. The one which can't adapt get extincted. Dianosaurs are the ones.
But even they could live for some time may be just because the time they lived, they had plenty of food and temperatures were low. Imagine such huge body consumes quintals of food and due to metabolism how much of heat is generated. Such enormous heat if its not dissipated, the poor being is going to die.
Now if the surrounding temperature is low, then there is high chance of survival. But as time passed by temperature increased. Then few of them are intelligent enough to evolve. They developed these fins. What is basic principle is you have to have large surface area to volume. Then these fins are near trapezoidal. They dissipate the heat. All this can be designed in just considering the non homogeneous heat conduction differential equation.
The same is implemneted in computers processors, nuclear reactors etc...
