Post Attack day 3  

The vicious and violent attack occurred at 7.35 pm 
June 22, 2016 Wednesday

I underwent emergency surgery by Dr. Anshuman Manaswi
at night 1.30 am on June 23, 2016 Thursday

I was discharged from Nanavati Hospital on June 24, 2016 Friday

I started going to my shop from today

I have also started to write my bedtime stories from today



In 1907, Rutherford returned to England (from Canada) to take the chair of physics at the University of Manchester.

He along with the German physicist Hans Geiger (of the famous Geiger counter or the Geiger-Muller tube) developed zinc sulphide scintillation screens.

Zinc sulphide or ZnS acts as a luminescent material when added with minute quantities of impurities like silver or manganese (chemistry really is magic!).

These scintillation screens were the earliest forms of particle detectors.

After he got his Nobel Prize for Chemistry in 1908 for "The chemical nature of the Alpha Particles from Radioactive Substances",He teamed up with Hans Geiger and Ernest Marsden (also a New Zealander with the same name Ernest).

Ernest Marsden was then merely an undergraduate student under Rutherford, a nobody.

Hans Geiger was a visiting German physicist who had greatly impressed Rutherford.

Rutherford who had earlier discovered that uranium and radium spontaneously emitted alpha particles wanted to measure precisely their mass-to-charge ratio.

Mass-to-charge ratio is a physical quantity that is most widely used in the study of the electrodynamics of charged particles.

But how do u study moving particles which we cannot see even with a microscope?

Physicists have always used indirect means to investigate nature.

Rutherford knew that alpha particles could ionize air molecules.

And if such an ionized air is subjected to an electric field, current will be generated.

On this principle (and not principal), Rutherford and Geiger designed a simple counting device consisting of 2 electrodes in a glass tube.

Each alpha particle that passed through the tube would create a pulse of electricity that could be counted.

This would be the primitive version of what would one day become Geiger counter.

We shall continue to dwell on this fascinating experiment in the nights to come.

You may wonder why I spend so much time on experiments and personalities who conducted them.

Well...To study nature as a body of facts is fundamentally wrong as then it remains no different to the study of a religious book.

Unless we can teach ourselves how we had investigated and how we SHOULD investigate nature, study of science is useless (as is plainly seen from the people around us).

Good night mon ami and my fellow cousin ape.
