Wound science from high velocity missiles at Princeton
A four man research team at Princeton University used ultra high speed motion pictures and microsecond X rays to study how high velocity bullets injure limbs. Tests on animals involved sleep agents and lethal doses, with shots fired to measure blood loss and fracture patterns.

High Velocity Bullets Cause Explosive Tissue Damage
A study using eighth and three-sixteenth inch steel projectiles at about 3000 feet per second reveals rapid tissue bulging and large-area disorganization around the wound. Postmortem dissections show bone breaks, nerve and vessel displacement, and tissue cavitation similar to a miniature TNT blast. Gelatin and water tests illustrate shock waves and recoil patterns analogous to earthquake rays, aiding military medical treatment.

Illusion of Depth From Two Camera Shots For Science Clubs
Junior Scientists describe creating stereoscopic pictures with two rapid successive shots from a single camera. They advise shifting the camera about 2 3/16 inches, aligning prints on one sheet, and viewing through twin lenses to merge into a single image with depth.

Altimeter to Improve Flight Safety Over Skyscraper Cities
New long range radio altimeter installed on transport planes provides continuous height readings from ground level to 400 feet. It reduces crash risk over cities with tall buildings by signaling altitude changes and aids blind landings. Derived from wartime Army air forces tech, it measures terrain distance by reflected signals.
