Science Fun With A Hot Drink


Here is a most enjoyable physics experiment that anyone can do almost anywhere.

You will need:

1 hot drink,
1 comfortable chair,
1 table or desk.

You will not need:

1 thermometer.


Having made yourself a nice steaming hot drink, sit in the chair and put the cup on the table.
You may, if preferred, put the cup on the table and then sit down.  This will in no way affect the validity of the results.  However, if you sit on the table and put the chair on the cup you are likely to invalidate the entire experiment, so stop being so silly!

How to sell a broken hockey stick

How plausible are AGW theories in general?

I will address that question using the sort of logic that can be programmed into a computer to simulate human intelligence: semantic logic.
