What is the application of science and technology in the Olympic Games?

Is to use advanced scientific achievements in sports competitions. For example:

I. 2000 Sydney Olympic Games:

Shark-skin swimsuit

Australian star Thorpe won three gold medals in this bathing suit for the first time at the Olympic Games. Many swimmers try to enhance their competitiveness by using a "shark skin" one-piece swimsuit with a V-shaped back. Because according to Speedo, the manufacturer of this swimsuit, it can improve the speed of swimmers by 3%.

Characteristic racing suit

Marion jones in the United States, Cathy Freeman in Australia and other sprinters all use special sportswear developed by Nike. This kind of running suit is very sleek and has a hood, which can cover all parts of the sprinter except the face, hands and feet. This can keep the muscles warm and compressed, and improve the performance of sprinters.

Recycled product sports equipment

Steve Moneghetti, an Australian marathon runner, took part in the competition in shorts and vest made of recycled soft drink bottles. According to the manufacturer Nike, this material is cooler than other fabrics.

Second, the 2008 Beijing Olympic Games:

Digital lamp

The Olympic rings rose slowly in the Bird's Nest and flew into the vast night sky. China ancient painting and calligraphy scrolls slowly unfold, showing the classical artistic conception of ink painting; On the ancient Silk Road, huge wooden boats braved the wind and waves-these shocking visual effects were outlined by the gorgeous lights of the Bird's Nest.

mixed-media

At the opening ceremony of the 2008 Olympic Games, "birds" and "whales" flew and swam freely on huge scrolls. How did these come from? It turns out that the previous opening ceremony used slide projection technology, and this time it used various multimedia equipment.

It can use computers to digitize text, graphics, images, animations, sounds, videos and other media information, and then integrate them into a certain interactive interface, thus creating a bowl-shaped screen of thousands of square meters at the top of the Bird's Nest, showing the clear picture of whales swimming freely and expressing the harmony between man and nature.

Digital ignition

Twenty-nine huge colorful footprints made up of fireworks opened the curtain of the 29th Beijing Olympic Games, symbolizing that the modern Olympic Games are coming to Beijing step by step and entering the Bird's Nest. The lighting of these 29 large footprints is controlled by computer system, using digital lighting. This technology can ignite all fireworks in a short time, ensuring that fireworks can cross 3.5 kilometers in just a few seconds.

Three. London Olympic Games 20 12:

Photographic robot

Getty Images, the official photo agency of London Olympic Games, installed photographic robots in some Olympic venues, which can realize remote control and 360-degree rotation. Photographic equipment can be hidden in flashlights, rafters and scaffolding, and placed in and around Olympic venues, which is most effective in places where photographers can't reach because of distance and safety reasons.

Double runway

The runway of the main stadium of the London Olympic Games has adopted a brand-new surface, which means that track and field athletes do not need to wear spikes to participate in the competition. Different from the past, these functions are divided into two layers, the bottom layer is padded, which can play the role of cushioning and shock absorption, and the top layer is firm and durable, which can maximize the anti-sliding, adhesion friction and durability. This design makes it unnecessary for athletes to wear spikes on the runway.
