What do you know of scientists who have worked hard to find out what they have done?

It took Marie Curie 45 months to extract radium from waste slag.

Edison failed a thousand times when he invented the electric light, and finally succeeded... ==American physicists Michelson and Morey, through the Michael Morey experiment, finally proved that the speed of light is eternal, and that there is no such thing as an ether.

Albert Einstein worked tirelessly to write the theory of general relativity that solved the precession of Mercury's perihelion.

Edison: Edison tried to make electric lights, and I don't know how many experiments he did in order to find a filament that was cheap and could be used for a long time. He often worked in the laboratory for dozens of hours in a row, and he was so tired that he lay down on the laboratory bench and slept for a while.

With such unremitting efforts, he finally found the right filament and invented the electric light. Later, Edison invented the motion picture and the phonograph, ......He invented more than 1,000 things in his lifetime.

Edison failed thousands of times before he finally invented the electric light.

Albert Einstein worked tirelessly to write the theory of general relativity that solved the precession of Mercury's perihelion.

Newton, Newton was hit by an apple back then, but he didn't think the apple hit him, but wondered why the apple hit him, so he discovered gravity after hard work.

Edison's invention of the electric light failed thousands of times, and finally succeeded once.

Give examples that reflect the perseverance of scientists and the hard work of Hayes Hon.

Here's how: Bauer Hayside is an American scientist who studies snake venom. As a child, he saw thousands of people around the world being bitten by poisonous snakes every year, and he was determined to develop an anti-poison.

He thought that if a person suffers from smallpox, he will develop immunity, and whether it is possible for a poisonous snake to bite and develop immunity, and whether the antivenom produced in the body can be used to resist snake venom, he imagined that this is also possible.

Therefore, from the age of 15, he injected himself with a tiny amount of venomous snake glands, and gradually increased the dose and toxicity. Such trials are extremely dangerous and painful. With each injection, he had to get seriously ill.

The venom components of various snakes are different, and the mode of action is also different, and each time a new snake venom is injected, the original antivenom is not competent, and it has to be tortured by a new antivenom.

Hayside analyzed the antivenom in his blood and tried to develop some anti-venom drugs, which have treated many people who have been bitten by poisonous snakes. He has been injected with 28 kinds of snake venom. After never giving up the experiment, there is finally a harvest.

Due to his own anti-toxicity, the king cobra, the Indian blue snake, and the Australian tiger snake have all bitten him, but each time he escapes from the side of death, the blue snake is extremely poisonous, and Hasted is the only person in the world who has been bitten by the blue snake and survived. He has been bitten by poisonous snakes a total of 130 times, but he still does not give up on contributing to the cause of human health.

Extended Material: The Case of a Diligent Scientist Euler.

In 1920, under the protection of Professor John, the 13-year-old Euler was fortunate enough to enter the junior class of the University of Basel, thus establishing a solid foundation for Euler to gallop in the kingdom of mathematics.

Under John's individual guidance and rigorous training, at the age of 17, Euler became the youngest master's student ever in Basel City for his outstanding aptitude in mathematics.

The intelligent and hard-working Euler is not satisfied with the content of the lecture in class, and always uses the weekend time to let Professor Yue Fan teach alone. Old John loved his talents, so he put all his housekeeping skills together, so that Euler's mathematical talents were rich and growing day by day.

Since the age of 18, Euler has been collecting research results for publication. Every time a new work appears, it causes quite a stir in the mathematical community.

In particular, his work on the mast of ships, published in the Mathematical Forum, was awarded a prize from the Paris Academy of Sciences. Looking at this fledgling young man standing on the highest podium in mathematics, people can't help but express their heartfelt admiration. Euler did not indulge in the sea of flowers, but remembered the motto of his mentor John, "Always Forward", and forged ahead to a higher goal.
