Now used alternating current engines, radios, radios, radars, fax machines, vacuum tubes, neon tubes, as well as death rays, X-rays, the dynamic theory of gravity, the first 100,000 horsepower power station was invented by him, Nikola Tesla independently developed and obtained 700 patents in his life, cooperated in the development of more than 1,000 kinds, and helped develop countless more, but did not put a penny into his own pocket.

    In his later years, he published the "dynamic theory of gravity", which even said that it could slow down the teleportation of Kiri, and in 1908, he was able to do that kind of disturbance back to Hiroshimahara. Child. The release of 1,000 times the energy of the bullet is the only person in the world who can control the "ball lightning" wheel.

    Tesla once said something like: "I can." Chop.

    1. The shape of the submarine: the shape of the submarine imitates the whale, which can reduce the resistance of traveling in the water, reduce the noise, and increase the concealment ability; The working principle of the submarine is to imitate the work of a fish bladder.

    2. Electronic frog eye: According to the visual principle of frog eye, the electronic frog eye was invented. Electronic frog eyes can identify objects of a specific shape with the same accuracy as a real frog eye.

    After the electronic frog eye is installed in the radar system, the anti-jamming ability of the radar is greatly improved. This radar system can quickly and accurately identify specific shapes of aircraft, ships, missiles, etc. In particular, it can distinguish between real and fake missiles and prevent the real from being confused with the real.

    3. Radar: Bats use "ultrasound" to navigate at night. The larynx of the bat emits a high-frequency sound wave that exceeds the sound of a person's wide ears, which travels in a straight line and returns quickly as soon as it touches an object.

    Radar uses this characteristic to create radar based on the echolocation system of bats with the help of the principle of biomimicry.

    4. "Compound eye" digital camera: Scientists were inspired by the structure of bees and flies with compound eyes, and invented a "compound eye" digital camera. This camera hemispherical arrangement of 180 microlenses gives it a 160-degree field of view, enabling it to focus on different depths of objects at the same time.

    While the human eye and all cameras use a single lens to focus light onto a light-sensitive tissue or material, an arrangement that produces high-resolution images, the compound eye offers a unique advantage in that it produces a panoramic view of the light and presents a significant depth of sense.

    5. Aircraft: The invention of the airplane originated from the human yearning for flight and the study of birds, in modern times, due to the development of aerodynamics and mechanics, people gradually understood the principle of bird flight, because of the shape of the bird's wings, the speed of the airflow through the upper surface of the wing is faster than the speed of the lower surface, resulting in the upward airflow pressure on the lower wing surface is greater than the downward airflow pressure on the upper surface by the nuclear fibrillation, this pressure difference is the lift, and thus the aircraft is manufactured.
