Theo Jansen He is the leading artist of kinetic art with the nickname of Da Vinci in the 21st century. He is famous for making wind-driven structures using simple materials such as PET bottles, tubes, and cable ties. Since 1990, … more
Charle’s Law Assuming constant pressure, increasing the temperature of the gas will speed up the molecular motion. As the gas often collides with the vessel wall, the volume increases. Conversely, if you lower the temperature of the gas, the molecular … more
Boyle’s Law If you press the piston of a syringe containing a certain number of gas molecules, the gas molecules’ space is reduced. Therefore, the gas molecules collide with the syringe wall more and more. As a result, the pressure … more
Apparent Motion of Mars If you observe the motion of Mars, you can see that you go forward and go backward. This procession of Mars has been regarded as mysterious since ancient times. In the past, the human did not … more
Three elements of force When a force acts on an object, the object’s motion varies depending on the Three elements of force. That is the magnitude, direction, and point of action. Therefore, when displaying a force, you must indicate the … more
Water Wave When you throw a stone into a calm lake, a circle of concentric waves is created and spreads around. The phenomenon that vibration created in one place spreads to the surroundings is called a wave. If you make … more
Triangle Regular Triangle The lengths of the three sides and the angles are the same. The size of each of the three angles is 60 °. It is the only triangle in which the inner center, circumcenter, and center of … more
You can drag ‘start’ and ‘endpoint.’ Thermodynamics of Gas The gas changes its temperature while exchanging thermal energy with the outside and sometimes does work outside as it expands or contracts. The process of changing the temperature, pressure, and volume … more
Resistance is analogous to a toll-gate, meaning that it limits the flow of current. Please note that excessive analogy may cause misconceptions. (The cars in the simulation are crowded out, but the actual charges are evenly distributed throughout the conductors.) … more
Pythagorean Theorem When the three sides of a right triangle are a, b, and c, and the longest side is c, the following equation is always true. The areas of a square with sides a, b, and c is a … more
