Semi retired old time computer nerd who started programming on a Commodore Pet.

Since I'm also active in the Physics forum I should add that I started as a theoretical chemist, moved into solid state photochemistry and finally worked in industry as a colloid scientist. I only became a full time computer nerd in 1997.

comment Approximating energy loss caused by drag force
The question I've linked isn't an obvious duplicate, but in my answer to it I do the calculation you describe.

comment Single particle passing through the double slit at a time
Hi Pratik. See the question I've linked for an explanation. having only a single photon at a time present shows that the effect can't be due to two different photons interfering. A single photon must travel through both slits.
