Galilean Transformation – v’ = v +- V – cannot be applied to light If (x1 , t1) and (x2,t2) are two events in K, and (x1’,t1’) and (x2’,t2’) are their co-ordinates in K’, then (x2 –x1) / (t2 –...

A Logical Paradox – The British Air Force Bombing Paradox The British Airforce announces that it will bomb the city sometime during this week; but at an unpredictable date. Why is this paradoxical. Suppose, they announce this...

Several classical, common sense notions like the momentum of a particle hold no meaning in the quantum realm. Momentum and velocities are no longer ‘material’ aspects of a microscopic particle; they are rather...

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...
