Sierpiński curves are a recursively defined sequence of continuous closed plane fractal curves discovered by Wacław Sierpiński. Fractal’s self-similarity Fractal curves retain their original shape even if they are greatly enlarged. Most fractal curves produce the … more
What is an image? Our eyes are designed to sense where the light came from. Even if the light didn’t actually originate there, if our eyes feel that way, our eyes say there’s an image there. … more
Water vapor in the air Liquid water can evaporate and turn into water vapor in the air. Conversely, water vapor in the air may turn back into the water. Some are very dry, with no moisture … more
Convection When you boil water in the kettle, even if you heat only the bottom, the whole water becomes evenly hot. This is because water transfers heat while moving directly. In this way, liquid or gaseous … more
Epicycloid refers to the trajectory drawn by a vertex on a small circle when a small circle is rolled outside a large circle. The radius of a large circle is denoted by R, the radius of … more
Definition of Trigonometric Functions In the right triangle, The longest side of the right triangle ‘c’ is the hypotenuse, ‘a’ is the base and ‘b’ is the height. You can assume that the angle between a … more
The inertia of the rocket Since there is no friction in outer space, stopping a rocket’s engine in motion does not stop it immediately. When the rocket’s engine is stopped, the rocket continues to move forward … more
Magnetic Induction When the magnet is placed close to the clip, the clip sticks. And when the magnet is attached to the refrigerator, it does not fall. Also, when two magnets are brought close together, they … more
Goals of coding The room is filled with dirty dust. You must order the robot vacuum cleaner to clean the room. Combine the blocks to make the room clean. Not all blocks may be used.
Goals of coding Baby larvae are scattered all over the place. We have to order the nanny ants to collect the larvae. Combine the blocks to make the nanny ant collect the larvae.
