Famous scientists born in the year of the mouse

The doctor who found Down syndrome, the "father" of modern tires, the inventors of trains on 1 track . were all born five mice.

Who found Down syndrome

According to the New York Times , Down is a genetic disorder due to three 21st chromosomes.

People with Down syndrome almost have physical and intellectual disabilities, usually as young as 8, 9 years old. The immune function of people with Down is also worse, the ability to develop later.

Especially, the name of the syndrome is named after John Langdon Down (1828, Mau Ty - 1896). Having attended many famous medical schools and hospitals in England, he was the first to describe Down's syndrome in 1866.

At that time, although the understanding of genetics was not as widespread as it is today, he affirmed that there was an agent of nature affecting the intellectual and physical disabilities of many births in London.

He also realized that there was a correlation between maternal age and the likelihood that children with Down syndrome, the older they were, the greater the likelihood of getting the disease.

Currently, medicine presents the number of children with Down syndrome in about 1 / 1,500 mothers under 25, 1 in 1,000 mothers over 30 and 1 in 100 mothers over 40.

Father of a tire

John Boyd Dunlop (1840, Canh Ty - 1921) was an inventor and an Irish veterinarian.

According to the Daily Mail , in 1887, when he heard his young son complain about a three-wheeled wooden toy scooter so awkward, Dunlop came up with the idea of ​​finding an alternative material to make the move smoother. Dunlop thought of making a rubber tire and inflating the inside of the rubber, a prerequisite for modern wheels.

He pumped air into a rubber tube and fitted it to his son's wooden wheels.

In 1888, he registered the patent and was officially recognized. The Dunlop Tire Company was born and is still a well-known name for manufacturing and manufacturing this product.

Trains on 1 track

In the Washington Post , Louis Brennan (1852, Nham Ty - 1932) was an Australian-born Australian engineer and inventor. His greatest success was the invention of a train that ran on a track, thereby creating a new step for the transportation industry.

This type of track allows the car to run at a higher speed, keeping the slope more stable in the corners. However, many people doubt the safety of the railway so no one dares to invest.

It was not until 1904 that Brennan received help to build an experiment . a test model. The 2-meter railhead of the same model is a 800m-long track designed with both curves and side roads.

This success has helped Brennan receive investment from the British Government. In addition, this initiative is also the foundation for many other single-track models such as some models of roller coaster, electric train, high-speed train .

The first French were Nobel chemistry

According to The Guardian , Ferdinand Frédéric Henri Moissan (1852, Nhâm Tý - 1907) was the first French chemist to receive the Nobel Prize in chemistry in 1906 for the work of isolating fluorine - one of the dangerous substances for humans. - used to kill many scientists. From there, the working environment in the laboratory with Flo became safer.

In addition, Henri Moissan discovered a new mineral in 1893 when testing rock samples from meteorites in Arizona (USA). Initially, Moissan thought it was a diamond, but after nearly 10 years of discovery, until 1904, he discovered that this is silicon carbide (SiC).

Later in his memory, the new mineral was named Moissanite .
