The talented students of the year of Pig

In the history of the world, many talented students in the Year of the Pig (1839, 1959) left many legacies for humanity.

The first electric car

Gustave Pierre Trouvé (1839-1902) is an electrical engineer and a famous French inventor.

Born in a middle-class family living in cattle trading, Trouvé could not complete his education and followed his job as a locker.

In 1865, Trouvé opened an electrical shop in Paris and began to love inventions. He was able to assemble proficient electrical equipment, and create unique devices that were up to the scientific journal La Nature at the time.

In the 1870s, he explored a series of new products, including a mobile telegraph for the military, an underground metal detector that was later used as a mine and electric detector. Voice with microphone can move .

However, Trouvé's life-giving product is the first electric car in the world. The tricycle is equipped with a 0.1hp direct current electric motor and powered by electricity from lead-acid batteries. The weight of the entire vehicle and the driver is about 160kg.

At first, people did not pay much attention to this event because the car was not complete enough to completely replace the horse rickshaw when only reaching the speed of 15km / h and within 16km.

In 1864, Trouvé improved his electric car and attended the race from Paris to Rouen with a distance of 1,135km during 48 hours 53 minutes, with an average speed of 23.3 km / h, far exceeding the speed of the car. horse pull.

Since then, the public has become more and more interested in this product of Trouvé - the basis for later cars.

The father of vector calculus

Josiah Willard Gibbs (1839-1903) is an American chemical chemist and one of the founders of vector calculus.

Gibbs received his doctorate in 1863 at Yale University (USA) and then continued to work with Oliver Heaviside and introduced the concept of vector calculus for the purpose of applying in physics.

In the late 1860s, Gibbs wrote the first work on vector calculus to teach his students. Later, all his lectures on vector calculus were collected and printed into books in 1901.

In the field of physiochemistry, he is known for his work in thermodynamics.

His most important works are printed in the form of Balance of Non-Homogeneous Materials, which is the basis for the chemical thermodynamics. He is also the one who gives the concept of chemical potential and transform function.

Scientist won the Nobel Prize each . ban

Mr. Koichi Tanaka was born in 1959 in Japan as one of the special Nobel laureates.

When he was young, he did not dare to talk to his friends, so people often thought of him as a fool. He is often bullied by older friends.

At the age of 18, he tried to pass the entrance exam to the Northeast University - one of the most elite schools in Japan, but had to retake it for a year due to poor performance.

Because of his poor education, when he graduated, the teacher in charge commented to him: "I have never seen such a poor student."

When looking for a job, Koichi Tanaka was rejected by large companies to become an engineer and to work in a small company that specialized in instrumentation.

When he was 28 years old, the company wanted to create a new product, so he was part of a research team that measured the quality of biological macromolecules, but this left his engineering and technical specialty.

In the process of learning while working, Koichi Tanaka has discovered a unique mixture that successfully separates molecular weight in 10,000 compounds.

It is worth mentioning that, this discovery came at a chance, Tanaka accidentally poured Glycerin into Cobalt reagent but continued to use the mixture as the reagent was very expensive now.

Tanaka is regarded as the least qualified Nobel laureate - (Key: House).

Thanks to that work, Tanaka has shown that it is possible to use spectroscopic techniques to determine the presence of proteins in the sample, thereby making it easier to study proteins, especially in solutions. Previously, this technique was only used to identify traces of chemical elements.

Koichi Tanaka won the Nobel Prize in Chemistry in 2002, and is also considered a Nobel Prize winner with the lowest degree, even less intensive in chemistry.

Before receiving the award, almost no scholars knew about him, and his material was not uploaded to the scholars' literature.

But by the time he owned the Nobel Prize, his former university had granted him an unconditional doctorate in chemistry.

At that time, he interviewed the newspaper in a rustic way: "After obtaining my doctorate, my plane ticket was free to upgrade to business class tickets, I was never in the business class seat. , I will try it a little later. "
