Rocket Science 101

Sir Isaac Newton was ahead of his time, developing the foundations of forces and motion that have taken "rocket science" from science fiction to reality.

Subject: Forces & Motion (Newton's Laws)

How Geometry Lends a Hand for Prosthetics

Armed with math concepts like geometry, APL engineers are learning how to build and control mechanical limbs whose complexity rivals that of the human body.

What Figure Skaters and Satellites in Orbit Have in Common

An APL engineer describes how the same principles that explain the beauty of an ice skater in motion also help launch satellites into orbit.
