Osmosis

Osmosis

Osmosis Osmosis refers diffusion of water molecules through a semipermeable membrane from a place of higher water concentration to a place of lower water concentration until the concentration on both sides is equal. It is the same principle that plants … more

Nuclear Chain Reaction

Nuclear Chain Reaction

Caution This simulation is intended to understand the principle of fission, and the proportions of the model presented may not match the reality. The nucleus was exaggerated and drawed large. The electrons around the nucleus were not shown. The principle … more

Lorenz’s Water Mill Simulation

Lorenz’s Waterwheel

Lorenz’s waterwheel Let’s say you have a waterwheel with a bucket with a small hole in the floor. When water drips from the faucet above, the bucket runs down and spins. Then, let’s predict which direction the waterwheel will turn. … more

Life Game

Life Game

The Life Game is a cellular automaton devised by the British mathematician John Horton Conway in 1970. The universe of the Game of Life is an infinite two-dimensional orthogonal grid of square cells, each of which is in one of … more

Inertia

Inertia

Run Inertia When the bus starts suddenly, the body momentarily leans backward. On the other hand, when the bus stops, the body is leaned forward. This is due to the nature of the object to maintain its current state of … more

Heat Capacity

Heat Capacity

Heat capacity ‘Heat capacity’ is the amount of heat to raise the temperature of an object by 1℃. The heat capacity of an object is the specific heat of the object multiplied by the object’s mass. Since the heat capacity … more

Specific Heat

Specific Heat

Specific Heat When you apply the same amount of heat to metal and water of the same mass, the metal temperature change is greater than that of water. This is because the amount of heat required to change the temperature … more
