Four-stroke Otto engine

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

The Moon

The Moon is the Earth's only natural satellite

Structure of nitrogen molecules

This animation demonstrates the structure of nitrogen molecules, with one sigma and two pi bonds holding the atoms together.

Phase transitions

A phase transition is the transformation of a substance from one state of matter to another.

Electron configuration of calcium

This animation shows the electron configuration of the calcium atom.

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.

Maglev Trains

One of the most modern means of transportation is the Maglev, capable of traveling at speeds of over 400 km/h (248.6 mph).

The development of celestial mechanics

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

Generators and electric motors

While generators convert mechanical energy into electrical energy, electric motors convert electrical energy into mechanical energy.

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.

Transparency

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

Mars Exploration Program

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

Chain reaction

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

Dynamo (intermediate)

A dynamo converts mechanical energy into direct current.

Elementary particles

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

Cloud formation, types of clouds

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

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.

Nuclear power plant

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

Electric bell

Mechanical bell that functions by means of an electromagnet.
