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 Why should we believe in clock hypothesis?
@sure: What we call the event horizon is a coordinate singularity, and is a result of the coordinate choice we've made i.e. the Schwarzschild coordinates. Jump into a black hole and you will encounter no horizon - in the coordinates of a freely falling observer there is no coordinate singularity. By contrast the singularity at the centre is a real singularity due to the curvature becoming infinite, and all observers in all coordinate systems will agree that it's there.

comment Why Do Clouds Precipitate Rather than Fall From the Sky?
The water droplet size in clouds is small enough that the rate of fall is negligable. Are you really asking what causes these water droplets to coalesce then fall as raindrops?

comment Ways to measure the focal length of a convex lens with only natural sun light
This question appears to be off-topic because it shows insufficient willingness to get off your butt.

comment Ways to measure the focal length of a convex lens with only natural sun light
A quick Google would answer this in seconds. Given that todays students don't even have to get off their butts and walk to the library, there's really no excuse for not looking this up yourself.
