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 How does a lightning striking stall a moving car?
@carlos: raising the potential of the car relative to the ground would not change the potential difference across the spark plug.

comment How does a lightning striking stall a moving car?
A colleague of mine claims to have seen this happen to a car, though in that case it restarted immediately. My guess is that the EM pulse reset the ECU.

@user3422157: I can't comment unless you post details of the drive design. Ideas for interstellar drives are ten a penny. You might want to post this as a new question, but bear in mind that most working physicists would probably consider interstellar drive design as recreation rather than science.

comment The origin of the colour of the sun
@Eliza: in principle you are emitting a small amount of visible light. I would have to do the calculation to find out how much. WhatRoughBeast is correct to say that true black bodies are rare, but in practice most things have an approximately black body spectrum.
