thanks for your reply in turkish,degree meaning:derece(in physcis) for example sıcaklık bir kaç saatte 15 derece düştü The temperature fell fifteen degrees in as many hours temperature:sıcaklık degree:derece (degrees:derece-ler- ) but,in turkish , heat,meaning:ısı heat units: Calorie -Joule.(not degree) I know,degree is not heat unit in english(or in other languages) but,because of -a degree of heat-......I am confused

Show that: if the sum of the digits of a natural number N is divisible by 3 then 3 | N.

a degree of heat?? I didn't understand:confused: The term degree is used in several scales of temperature.

thanks...big bang (of course physics) ....every time is a good topic/subject

well The Universe = Space and Time ??? right or wrong?

thanks Martin An Interesting Approach

A student places a row boat in a swimming pool, loads the boat with a number of bricks, and rows to the center of the pool. Once there, the student carefully notes the water level, throws the bricks into the swimming pool and once again notes the water level. What had happened to the water level in the pool?
