Day 10 post attack
BMC assistant engineer came to meet papa
The ugly deeds of Sanjay Veera was revealed to him.
Let me try to describe the wonderful apparatus that Geiger and Marsden had built.
It was essentially a hollow metal cylinder mounted on a turntable.
The cylinder was free to rotate independently.
Inside the cylinder was a metal foil (F) which would be object of bombardment.
Radon (R) which would again be the source of the alpha particles was mounted on a detachable column (T).
This column also served as a tube to suck out air from the cylinder.
A microscope (M) penetrated the wall of the cylinder from the side was pointed towards the gold foil.
The objective lens of the microscope was covered with the zinc sulphide screen (S) which as we know served ad the detector for the scattered alpha particles.
By turning the table (speaking literally), the microscope could be made to move a full circle around the foil.
This would allow Geiger and Marsden to observe and count alpha particles deflected by as much as 150°.
They further developed this apparatus for more sophistication.
But for tonight, I just wish you to savour and relish this ingenious apparatus.
For better visualization I will send you its schematic diagram.

Good night mon ami and my fellow cousin ape.
