Relativistic Calculator

Read full description

To calculate the elasticity of the time of your travels and the altitude/height at/in which you are. To illustrate time dilatation we shall take the example of twins. One of them leaves in the space and travels almost at the speed of light whereas the other one stays on Earth. While 20 years have elapsed for the latter, the traveler will not almost have aged. We can find the same phenomenon if both twins live on the planets with different gravity. We find all phenomena of less spectacular manners in our travels by car, train, plane and in the places we live in height or at the seaside. This application suggests opening of your spirit to this aspect of the physics which is badly known. These applications are more and more present in our lives. We propose a ludic approach to arouse curiosity and to enrich the scientific culture. A means of travelling in time towards the future is thus to travel at almost the speed of light to slow down time. This application enables you to know how much time you gained towards the future during your trips.
