The lost square puzzle is a visual illusion in which a triangle is reconstructed with 4 internal pieces, with a small square missing from the inside. In fact, there is a slight difference in the angle of the triangle from the top to the base in the second figure. That is, the area of the triangle in the second shape is larger. This small surface difference is equivalent to the small empty square.

Table of Escher and the Droste phenomenon The works of the Dutch graphic artist M. C. Escher is famous for its geometric patterns in replay, optical illusions, and the tall structures. Some of these create interesting math puzzles. This project named "print Gallery", It is a distorted image that uses the phenomenon droste (an image that appears inside herself), and deciphered by the two Dutch mathematicians Bart de Smit and Hendrik Lenstra.

Spectacular collapse of a part of the Perito Moreno glacier In Argentina's Los Glaciares National Park, Spectacular footage has been captured of a huge chunk of the Perito Moreno glacier breaking off and emerging from the surface of the water, gradually revealing its submerged part. The height of the Perito Moreno glacier is 170 meters, of which 74 are above the surface, while the rest are under the waters of Lake Argentino. With a length of 5 kilometers, the glacier is slowly advancing into the lake facing the Magellan Peninsula. When he reaches the opposite bank, divides the lake in two, then acting as a natural barrier. The water level of Lake Argentino then rises to 30 meters and begins to cut into the glacier. As it becomes less durable, it buckles under the pressure.

A 1970's tank simulator This simulator from the 1970s uses a miniature world to simulate the driver's perspective, and was intended for training soldiers in chariot driving. At that time, the simulator was controlled by a bulky 1970s computer, but the museum was unable to put the parts together and rebuild this piece when they rebuilt the device. So now the emulator is controlled by a Raspberry Pi. The tank's tiny portholes are connected to a camera mounted on a miniature model. The camera is moved by a robotic arm based on the movements the user makes in the simulator.
