The phenomenon we are trying to explain is the interference pattern seen when you send a stream of particles through a double slit (barrier with 2 slits) apparatus. As long as you do not make any measurement, you ALWAYS get an...

Just like the Standard Model for elementary particles, the model for cosmology also has 15 adjustable constants.

This post is under construction For example, if the (one dimensional) position of a particle consisted of a normal statistical distribution with a mean position of 0m and a variance of 1 at time t = 0, it’s wave function...

A number that ranges from 0 to 1 – to capture the Income inequality for a COUNTRY. By itself, the number means little, but in comparison with other countries, can convey much. A GINI index of 1 – would be if ONE family had...

Three doors, a prize behind only one door (say, a new car). Other two doors are each hiding a goat. Contestant has to pick a door – and hope that she wins the car. At just this stage, the chance of her winning the...

Where I grew up, we were taught math the hard way. We HAD to struggle through problems. No matter how complex or convoluted the problem was, it was almost a given that students would stay up – until they had solved it...

Nothing heckles our common sense notion of ‘time’ more than Special Relativity. Consider a muon particle decaying as it enters the earth’s atmosphere. As per the muon, it should only live a few microseconds. Not...

A Lie algebra is simply a) a vector space b) with an “operation” such that the operation [x,y] of any two vectors x and y is again a vector, and such that the following hold: skew-symmetry: [x,y] =...

Redefining distances – 1 A.U. – Astronomical Unit (Distance between Sun and Earth) = 150 million kilometres, Redefine 1 A.U. = 1 cm Solar System (radius) = 1 foot on this scale. Far Extreme of the Solar System...

Algebraic equations vs. Differential equations Galois Theory – dealt with symmetries in algebraic equations Lie – Tried to do the same (look for underlying symmetries). Lie Groups Are a Group Are a Manifold Groups vs. Rings...
