Four-stroke Otto engine

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

How does it work? - Laser

Lasers are devices designed to emit narrow, monochromatic, high-intensity beams of light.

The physics of bicycles

Some principles of physics can be demonstrated through the functioning of bicycles.

Electric bell

Mechanical bell that functions by means of an electromagnet.

Elementary particles

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

The life-cycle of the Solar System

The formation of the Sun and the planets started with the contraction of a dust cloud about 4.5 billion years ago.

Cloud formation, types of clouds

Evaporating surface water forms clouds of various shapes from which water falls back to the surface as precipitation.

Dynamo (intermediate)

A dynamo converts mechanical energy into direct current.

Nuclear power plant

Nuclear power plants convert the energy released during nuclear fission into electric power.

Covalent bonds in benzene molecules

In benzene there are sigma bonds and delocalised pi bonds between carbon atoms.

Lesser horseshoe bat

Bats use ultrasound to navigate and hunt for prey.

The Rutherford experiment

The Rutherford Experiment proved the existence of positively charged atomic nuclei. The results led to the elaboration of a new atomic model.

Development of the atomic model

Major phases in the history of theories and views about the structure of the atom.

Chain reaction

Energy released during nuclear fission can be used for civilian or military purposes.

Watt´s steam engine (18th century)

The steam engine, perfected by the Scottish engineer James Watt, revolutionised technology.

Mars Exploration Program

Space probes and Mars rovers examine the structure of Mars and possible traces of life.

Electron configuration of calcium

This animation shows the electron configuration of the calcium atom.

Kepler´s laws of planetary motion

The three important laws describing planetary motion were formulated by Johannes Kepler.

Transparency

This animation explains transparency and opacity, the principle of radiography, and the light-absorbing properties of materials.

The development of celestial mechanics

This animation introduces the studies of astronomers and physicists whose works fundamentally changed our view of the universe.
