Science Simulations
Arrange the element cards As Mendeleev did. You can move three or more consecutive cards as a group by dragging the middle. You can view it in full-screen mode by clicking the full-screen button. (There is a button between this … more
This App is a simulation of an electric circuit with a high degree of freedom. You can make the electric circuit you want by connecting batteries, wires, light bulbs, voltmeters, and ammeters. You can adjust the resistor value by clicking … more
This App is a simulation of an electric circuit with a high degree of freedom. You can make the electric circuit you want by connecting batteries, wires, light bulbs, voltmeters, and ammeters. By applying Kirchhoff’s Law, accurate measurements can be … more
Description of the simulation You can compare the two cases with each other. The power plant produced is assumed to be \( 22,000V \times 1A = 22,000W \). You can change the voltage and resistance of the transmission line respectively. … more
Record of movements The motion of an object can be more easily understood by graphing it. In the time-distance graph, the slope is equal to the velocity. The average velocity that an object has moved over a certain period of … more
Ion Atoms are made up of an atomic nucleus and electrons. Electrons far from the atomic nucleus may easily fall off, or electrons from outside may enter. If a neutral atom loses an electron, the amount of (+) charge becomes … more
Michelson interferometer The Michelson interferometer was invented by the American physicist Michelson. Although it has a simple structure, it can measure very small distance differences, such as the size of an atomic nucleus. The Michelson interferometer consists of the following … more
Twin Paradox Twin paradox started as a contradiction in ‘time delay’ in Special relativity. The Twin Paradox goes something like this: (Contents vary depending on the media.) One of the twins stays on Earth, and the other leaves Earth in … more
Minkowski Spacetime Minkowski spacetime (or Minkowski space) is a coordinate system devised by German mathematician Minkowski. The peculiar thing is that the coordinate system contains space and time. Minkowski spacetime uses matrices to express a four-dimensional coordinate system (x, y, … more
CAUTION: Read the following instructions to the end to get the result that the moving object appears to be constricted in length. (It is difficult to explain ‘Special Relativity’ only with the above simulation.) The meanings of the symbols used … more
The meanings of the symbols used in this simulation are as follows. L = Distance that light travels in a stationary state, (=ct｡) c = Speed of light (≒ 299,792,458 m/s) t｡ = The transit time of light observed inside … more
Icon Title Try popping the falling drops with your body. If your PC doesn’t have a camera, it won’t work. When the web browser asks for access to the camera, please allow it. (Personal data never stored on the server.) … more
