Four-stroke Otto engine

This animation demonstrates the type of engine most commonly used in cars.

Elementary particles

Matter is made up by quarks and leptons, while interactions are carried by bosons.

Lunar eclipse

Lunar eclipses occur when the Moon passes through the shadow cone of Earth

Newton’s Laws of Motion

This animation demonstrates Sir Isaac Newton's three laws of motion that laid the foundation for classical mechanics.

Our astronomical neighborhood

A demonstration of nearby planets, stars and galaxies.

Cloud formation, types of clouds
