Atom collisions simulation
This application allows you to simulate what happens when atoms fully elastically bounce against
each other in a box.
Depending on the speed of your CPU you should be able to simulate at least 1'000 atoms on a slow
CPU. On a modern CPU, simulating 100'000 atoms is also possible.
Slow CPUs can still do simulations of 100'000 atoms, but at a very low speed (FPS).
If you put too many atoms in too small of a space, you will get more of a plasma simulation rather
than an elastic simulation.
The simulation always tries to run at 60 FPS to reduce the energy used. So, even if your CPU is capable
of running the simulation faster, only 60 simulation steps are executed and shown per second.
If your CPU can't run at 60 FPS, then the simulation will run as your CPU allows for.

Instructions
User interfaceThe title bar of the window contains some statistics of the running simulation.
The left side contains the simulation.
The right side contains the settings.
The status bar contains info on the setting your mouse is hovering, and also the date and time.
Settings
Start/Stop button
The top right button is for starting and stopping the simulation.
World dimensions (width and height)
The world dimensions are for setting the size of the world's simulation. If the world size is too
and/or too wide, then scrollbars are automatically shown.
Background colour
The background colour allows you to choose the world's background colour. Although any colour
is allowed, some colours may make the atoms harder to see. White and black backgrounds give
a high amount of contrast, making the simulation clearer.
Tot atoms
The total amount of atoms in the simulation. The more atoms, the slower the simulation. Also,
if you choose too many atoms, they may not fit in the world.
Radius (min and max)
The minimum and maximum radius can be used to set the random size of each atom. If you
choose the minimum and maximum the same, then all atoms are the same size.
Note that the atoms have no mass, so bigger atoms have the same amount of energy in a
collision compared to smaller atoms.
Example 1
Have every atom be the same size.
Example 2
Scrollbars when the world is larger than your window.
Example 3
Non-square world dimensions.
Example 4
We can also do many atoms.
Example 5
When you have too many atoms, the simulation behaves more like a plasma.
Example 6
100'000 atoms on a 4k screen.
