Quantum mechanics

      I was reading "Essentials of Statistical Thermodynamics" by Nash today. Several things that he said made me realize a lot of truths about Stat ThermoDyn. He starts by saying that thermodynamics teaches us what happens and how much of it happens, but it does not tell us why it happens. Most such textbooks would probably say the same thing, and then proceed to drown us in jargon and all manner of equations. My favorite part is when these oh-so-smart guys shove my ignorance in my face by sating things like "It is trivial to extrapolate from this 3 term equation to a 30 term equation". And I am left wondering what the hell happened. Needless to say, from that point onwards I am too annoyed to make sense of anything. So Nash takes us through the subject with minimal assumptions and the Boltzmann distribution almost seems like a natural extension of basic probability which actually it is. So, reading his book got me thinking about a lot of other things and I ende...

Alien Invasion

      I was watching another alien invasion movie today. And I feel that this whole Martians/venusians or Alpha centaurians are vulnerable is a big problem with the whole genre. I believe that no civilization can really discover space travel without first discovering the secrets of health and disease. And if they have discovered that, then it is only a matter of time before they realize that they dont need huge machines and energy expensive robots and exoskeletons etc. All that they will do is send an earth-rover initially equipped with a small biological specimen collector/analyzer and find out the genetic makeup of earthlings. Once they do that, they will obviously realize that humans are susceptible to a lot of diseases. They dont need to understand english, they dont need to communicate with us (who the hell except us wants to anyway ?). It is our (rather Hollywood's) stupidity to think that Aliens would come to Earth and stand before us and in a comma...

Letter to atheists

Found this stupid letter to all atheists on the internet. Just had to send a reply. So here it is. My responses to the 'questions' preceded by "----". Dear Atheist, Do you think its a coincidence that... of billions of stars and planets in the many galaxies, only earth has life, and abundance of it? ---- what makes you think so ? the sun is 400 times the size of the earth's moon, 400 times further away from earth than the moon, yet they look both proportionally the same size in our sky? ---- Do you know how other moons look from their planets ? the sun lights the days nicely, while the moon glimmers in the night sweetly and the clouds bring forth rain to water our crops, which bring forth food in your stomach? ---- Mostly due to eart...
