Introduction Distinguish between 2-sphere \(S^2\) and 2-torus \(S^1 \times S^1\). Homotopy rubber band on \(S^2\) contracts to a point. For continuous maps \(f, g\), they are homotpic \(f \simeq g\) if there exists a homotopy between them. Check equivalnce relation. Identify homeomorphically \(S^n\) without North Pole with \(\mathbb{R}^n\), via Stereographic...

Generate Music using Quasicrystals and Cellular Automata
For my music friends, with many of whom my first discussion was on making algorithms for music- While studying certain mathematical structures called fractals in nonlinear dynamics, I was led to this applet that creates music from quasicrystals. There’s also two series of animated films on youtube on dimensions and...

External as mirror to see Internal
I spent all the years of my life searching for meaning and I don’t find it anywhere. I never met a person that had an answer. How foolish all of them seemed to me- Ignorant, full of vanity, fooling themselves to being purposeful, but beneath their superficial faces I knew...

End
Why are we afraid of death? Why do we have to rationalize it? Why do we have this bias? All we do in this life trying to collect things, gain things, accumulate. The Self keeps growing and we call that achievement. It’s a really simple game. Starting with nature, everything...
