Physics with Portals

Note: for folks coming in from Wired, here’s the thermodynamics of the ideal gas law video.

Fun with slow motion cubes, graphs, and data! I like this video a lot.

Console Commands:

sv_cheats 1 (only needs to be done once)
noclip (lets you fly around the room)
phys_timescale 0 (freezes objects in the game)
phys_timescale 1 (lets objects move normally again)
phys_timescale 0.25 (slow motion cubes!)
impulse 200 (removes/replaces portal gun)
bind “z” “noclip” (an example of linking console commands to keyboard shortcuts)
