A demonstration of two falling balls, which shows that, air resistance aside, bodies of unequal weight fall at the same rate. This is Newton's law of...

A pattern of air flow demonstrating the Bernoulli principle. A wing-shaped object placed in a wind tunnel acts as an airfoil, where the upper surface...

DNA, B form, 20 Base Pairs. A computer-drawn simulation of the colored plastic space-filling molecular models used by chemists, with spheres at the Va...

This image illustrates the law of reflection, which states that when a ray of light is reflected off a surface, the angle of incidence is equal to the...

Demonstrating the angle of incidence is equal to the angle of reflection. Captured using stroboscopic exposure.

Demonstrating the angle of incidence is equal to the angle of reflection. Captured using stroboscopic exposure.

Demonstrating the center of mass. A wrench hurled through the air seems to be tumbling erratically, but the path made by the X on its handle, marking...

There are three independant simple machines: lever, the pulley, the inclined plane. A wedge is similar to the inclined plane.

A candle reflected in mirrors, creating multiple images.

Time-exposed photograph of an animated model of a uranium-235 atom. The center represents the nucleus, greatly exaggerated in size. The fine lines rep...

X-ray showing contents of suitcase. This procedure is commonly used by the airline industry as a security measure.
