Science simulations
This simulation is works with Edge, FireFox, Chrome, Safari, Opera. does not work withInternet Explorer, Opera Mini. String instrument Since string instruments are tied on both sides of the string, the string’s end becomes the vibration’s knot. When the string … more
Fourier series The Fourier series is an infinite series that expresses a periodic function that repeats a certain part as the sum of simple trigonometric functions. A simple trigonometric function consists of a smooth surface wave. If you keep adding … more

This experiment is, You can experiment with heavy golf balls and light ping pong balls. Put a ping pong ball on top of the golf ball and drop it as it is. The golf ball hits the floor first. As … more
The ductility and malleability of metal When a force is applied to a metal crystal, the metal atom layer is pushed, and the atomic arrangement changes. But at this time, the free electrons move and maintain the bond between the … more
You can create various string art works by utilizing the computer’s fast computing power.
Parabolic motion Let’s think about the motion of throwing an object horizontally. There is no horizontal force when there is no air resistance, so there is no change in speed. This time, let’s consider a dropping. If the initial velocity … more
What will the reactant and product concentration curve look like over time? Click the button to start the synthesis reaction. Reaction rate Reaction rate refers to the degree to which a chemical reaction occurs quickly or slowly. The rate of … more
Radiation Places close to the stove feel warmer than places farther away. This is because heat is transferred directly from the stove without any movement of material. This phenomenon in which heat is transferred directly without the aid of a … more
Ester Ester is an organic compound having a -COO- group in the middle of its molecular structure. Esters usually have fragrances and are found in perfumes, herbal oils, and pheromones. It is also used as a flavoring material by many … more
Transistor There are so many switches inside your computer that you can’t imagine. It’s not the hand-pressed switch we’ve been seeing. It is a switch operated by an electrical signal. The computer counts ‘1’ and ‘0’ according to the voltage … more
The discovery process of the atom Democritus (Ancient Greece) – Predict the presence of an atom Dalton (UK, 1800) – Applied atomic chemistry Krux (Britain, late 19th century) – Invented a cathode ray tube to explain various phenomena of electrons … more
