Why Entrepreneurship?

The question "why entrepreneurship?" is similar to asking "why science?". I am making this comparision here because I consider both of them doing the same thing, creating hypothesis to the problem, testing testing them and reiterate. Scientists think in terms of nature and natural laws, entrepreneurs think in terms of society, economics, problems and opportunities. entrepreneurs find the inventions and opportunities and combine them to solve problem via new businesses. The r…

Meaningless

Life is meaningless, future is meaningless. What is the reason to live if we will have no trace of existence after few years of our death? Even if we leave a legacy, it will be an image of us. There is no personal gain in it. So why do it in first place? We want to make worlds a better place for future generations. Why do we need children after all? What is the goal? Just to forward the dumb animal race. In the far distant future, even if we conquer the galaxy and the universe, what will we do a…

Why do Integrated Circuits contain gold?

Gold is used in ICs for interfacing to the package. Copper can cause corrosion in the packagins. There are two solutions to avoid this, aluminium plating on copper pads or nickel/gold packaging. Gold plating is somehow found to be cheaper because it eliminates costs associated with the thin film sputter, photo lithography and metal etch. Gold also offers thermal stability for the package. With much advances in technology, Copper interconnects are being used instead. Conventional problems associa…

State Considered Harmful

I recently studied a paper that described how states on computers are a big security issues and proposes a laptop which holds no system at all, requiring all the components of a computer system including disk controllers, network controllers, microprocessor management engines stateless and hence increasing the security of our systems. References "State considered harmful A proposal for a stateless laptop", Joanna Rutkowska, December 2015. ↵

How To Choose a Good Scientific Problem

Choosing a problem is an act of nurturing. Problems can be easy/hard and can have small or large gain in knowledge. Easy/small knowledge gain: to get started Easy/large gain: postdoc or 2-5 year project Hard/large gain: long term (10 years or more) If you were the only person on earth, which of these problems would you work on? Take enough time to choose a right project. Work Breakdown Structure because the Work remaining will grow until you have a Breakdown, unless you enforce som…
