RDX

RDX is a is a high explosive. It is usually not used alone & is the main ingredient of C-4.

It is much more energetic then TNT, and it's the most powerful of the very commonly used explosives (nitroglycerine is actually more energetic in a few specialized tests).
RDX is much easier to make then both TNT & picric acid.

IK

Inverse kinematics, used extensively in character animation.

IK is the opposite of FK, forward kinematics. In FK, you move and rotate bones in order to make movement. For an arm (eg), you rotate the shoulder, the arm, the forearm, then the hand, to maybe get your character to hold something.

In IK, you'd start with the hand using an IK target, and move up from there if necessary.
Professional animator: IK is useless. Use motion capture instead if you want to really make moneys.
Hobby animator: IK is a lifesaver!
Noob animator: IK?
