Wow !!

There are moments in life when you sit back and wonder. I think mathematics and physics (well physics is just applied mathematics ;) ) is one subject which provides numerous such moments. I vividly recall my consternation when I was first taught that you cannot cool below absolute zero at 273.16 kelvin. That harmonic series is diverging and p series is converging. 2nd law of thermodynamics. There are different levels of infinity. Cantor's diagonal proof. Decimal expansions of Pi. Pi itself. Euler's constant e. Feeling after reading God Delusion. Conservation of energy that I couldn't make a self propelling vehicle by using two similar ends of magnets. The tea spoon mass of black hole could be so great that it could be higher than any known metal. Seeing Iron float on mercury. Bending of light through gravity. E = mc^2, Euler's formula. Making sense of complex number through matrices. That dipping your hand in liquid nitrogen will give you a cold burn so severe that your finger could splinter in to shards. Just trying to think about how big is infinity and how insignificant even our life is in the realm of our cosmos. That packing of elements in 9 dimension allows more room. Numerous mathematical puzzles.
