Who are people like Hawking?

He is a scholar involved in many fields, including philosophy, linguistics, logic and music. He also wrote articles about natural science, proving the existence of vacuum.

K. Christian birkeland

(1867- 19 17) is a pioneer in the study of geomagnetic field and northern lights. He guessed that the aurora was formed because the negative charge from the sun was attracted to the earth's atmosphere by the geomagnetic field. On the left side of this bill is a set of instruments and equipment that he simulated this effect.

Niels Bohr

(1885- 1962), Bohr is one of the main architects who understand the quantum theory of the nature of matter. He created the first atomic quantum model (Bohr model). He played an important role in the modern interpretation of quantum theory.

Boskovich (1711-1787) and Boskovich have made great contributions to orbital mechanics. He was one of the first scientists to speculate on the existence of force between atoms.

Copernicus

(1473- 1543), he was the first scientist to put forward the theory of the solar system, thinking that the sun is the center and the planets revolve around it in a certain orbit, instead of being supported by any invisible crystal sphere. His works were published after his death. Look at the summary of his biography and contact his environment at that time to know why.

Pierre curie and Marie Curie (Marie: 1867- 1934, Pierre: 1859- 1906), who led the discovery and classification of radioactive elements, won the 1903 Nobel Prize. Marie Guen won the second Nobel Prize 19 1 1 for her outstanding contribution to radium. Their daughter Irene Joliot-Curie also won the Nobel Prize.

Democritus (about 460 BC-370 BC

He was one of the earliest ancient philosophers who described that matter was composed of inseparable particles (atoms) moving in a vacuum.

Albert Einstein (1879- 1955),

As the greatest scientist in 2 1 century, Einstein not only discovered special relativity (the essence of high-speed moving objects) and general relativity (the theory of gravitational action), but also made a fundamental contribution to the beginning of quantum theory.

Leonhard Euler

(1707- 1783) He made great contributions to mathematics, including fluid flow theory (used to study how to make an airplane fly) and rigid body rotation theory (used for satellite control).

Michael faraday (179 1- 1867)

Faraday is one of the main discoverers of the properties of current and magnetic field and their relationship. This discovery laid the foundation for the use of electric motors and generators.

Benjamin Franklin (1706- 1790) is a pioneer in the field of electricity. He first proposed the conservation of charge.

Galileo (1564- 1642), in a sense, he was the first scientist. He discovered how to determine the critical state of a moving object.

Gauss (1777- 1855) not only made many contributions in mathematics, but also made important discoveries in electromagnetic theory.

Christiaan Huygens

(1629- 1695) Huygens was a contemporary of Newton and made many important discoveries and inventions. Because his self-made telescope has been greatly improved, he is the first person to find Saturn with rings (Gauss thinks it is a "triple planet"). He made the first pendulum that could greatly improve the accuracy of time measurement.

Marconi, the developer of the first successfully developed radio (1874- 1937).

Newton (1643 ~ 1727) can be said to be the greatest physicist in history. His work established a scientific method to explore the basic elements. He made an important discovery in kinematics-his understanding of the nature, gravity and material properties of light. (The following is taken from History: Britain on Banknotes) On the desk is the first reflective telescope he made, which is the basis of modern large-scale optical astronomical telescope. The main patterns in the left half of the back are various ellipses-celestial orbits dominated by gravity.

Hans Christian Osra Shedd (1777- 185 1), who discovered in 1820 that current would deflect a magnetic compass. This discovery marks the beginning of the unification of electric and magnetic phenomena.

Olafa Romer (1644- 17 10) was the first person to prove that the speed of light is not infinite. He used the irregularity of the moon and the moon to get an estimate of the speed of light.

Ernest Rutherford

(187 1- 1937) Rutherford and his students demonstrated an experiment to help people understand the explanation of atoms-most of the mass of atoms is contained in a very small center (nucleus), and the size of atoms depends on some tiny particles-electrons.

Irving Schrodinger, one of the main pioneers of quantum theory, explained that the properties of matter are caused by its components-electrons and nuclei. The success of this theory makes it possible to develop modern electricity, including transistors and lasers.

Nikola Tesla

(1856- 1943), born in Croatia, immigrated to the United States. He made an important contribution to the development of electronic technology. The above is a black-and-white scan of his inflation before the disintegration of Yugoslavia, with a face value of 654.38 billion dinars.

Alexandrov (1745- 1827) built a chemical battery.
