**Ask a monkey a physics question thread**

If you like times about time travel etc, check out - Timecrimes (2007) - IMDb . I really enjoyed it.

Will check out Primer, ty GMML.

Is Timecrimes in English? I hate reading a movie.

Fun list of all the laws of classical physics: These 13 laws describe nearly everything about the world you directly experience. These are the shortest possible descriptions I can think of, and I left out all the equations.

MOVEMENT
Newton's First Law: In an inertial reference frame, an object that is at rest will remain at rest, or an object that is moving will continue to move in a straight line with constant speed, if and only if the net force acting on the object is zero.
Newton's Second Law: The vector sum of all forces acting on an object will result in a change in the objects momentum.
Newton's Third Law: For every action, there is an equal and opposite reaction.
Newton's Law of gravitation:Gravity is an attractive, long-range force between any two objects.

HEAT AND WORK
Zeroth Law of Thermodynamics: If two systems are in thermal equilibrium with a third system, they are also in thermal equilibrium with each other.
First Law of Thermodynamics: In all cases in which work is produced by the agency of heat, a quantity of heat is consumed which is proportional to the work done; and conversely, by the expenditure of an equal quantity of work an equal quantity of heat is produced.
Second Law of Thermodynamics: No process is possible whose sole result is the transfer of heat from a body of lower temperature to a body of higher temperature.
Third Law of Thermodynamics: It is impossible for any procedure to bring a system to a temperature of absolute zero in a finite number of steps.

ELECTRICITY AND MAGNETISM
Gauss’s Law: Charged particles create an electric field.
Faraday’s Law: An electric field can also be created by a changing magnetic field.
Gauss’s Law for Magnetism: There are no magnetic monopoles.
Ampère-Maxwell Law: Moving charges create magnetic fields (Ampère). Changing electric fields also create magnetic fields (Maxwell).
Lorentz Force Law: The general force equation, which describes how matter responds to electromagnetic fields.

Zeroth Law

you're making this up now, surely?

just put a word-search in or something...no-one will read this far

I'm not making it up. And stop calling me Shirley.

It's the real deal. Google it.
The other 3 laws were worked out first, before someone realized that they didn't have any law that said "thermometers... they work".

The zeroth law basically states exactly that. A thermometer works by exchanging heat with the thing it's measuring until they are the same temp. The 2 objects are then in thermodynamic equilibrium. The thermometer has some scale and readout, so by knowing the temp of the thermometer, you know the temp of the thing you are measuring. If you then measure another thing and it measures the same temp on the thermometer, then it is the same temp as the first thing. LDO.

It was just so obvious that it was taken for granted.

Could I publish a paper with an equally obvious conclusion? I didn't see any laws listed there that say that if two objects are moving the same speed as a third object, then the two objects are moving the same speed as each other.

I'll be taking my Nobel Peace Prize now.

Actually, that's covered in Newton's First Law.

But don't let that stop you from thinking. There is a huge, enormous, gigantic hell of a lot that is left to figure out in physics, and someday, people will look back and think, LDO.

Oh, and there's a Nobel Prize for Physics and another for Literature (and others), so you got at least 3 chances to win!
