April 22 marks:
International Mother Earth Day, launched at the 63rd session of the UN General Assembly in 2009. This day is designed to remind that each of us owes our existence to our planet and its ecosystems, it has its own symbolism – the Greek letter “Theta” in green on a white background. The logo of the holiday is a picture of the planet taken by American astronauts from the Apollo 17 spacecraft.
Significant dates of this day:
1915 – near the Belgian city of Ypres, the German army in battles with the French used chlorine for the first time, covering six kilometers of territory and poisoning up to 15 thousand people, a third of whom died.
1921 – the city authorities of Chicago decided to fine from 10 to 100 dollars women who will appear on the streets in short skirts and with bare arms;
1943 – Albert Hoffman made the first report on the hallucinogenic properties of LSD;
1952 – 35 million Americans witnessed a live report from the Nevada nuclear bomb test site;
1967 – In Greece, a junta of “black colonels” came to power through an armed coup;
1969 – The first successful human eye transplant operation was performed in Houston;
On April 22, 1992, in the city of Guadalajara (the second largest city in Mexico), there were 4 series of explosions that lasted 4 hours and 14 minutes. At that time, 252 people died, more than 1,440 were injured, 15,000 people were left homeless, 450 enterprises were destroyed, and the damage amounted to between 300 million and 1 billion US dollars.
The cause of the explosions was a temporary worker hired in 1980. He laid sewage pipes in the same trenches as the gas line. The water pipes were galvanized and the gasoline pipes were made of steel, a combination that led to corrosion. The result of the gasoline leak caused a series of explosions that practically destroyed the city. A few days before the disaster, people complained about the smell of gasoline, but the authorities denied the danger of an explosion on the radio. A real “butterfly effect”!
On April 22, 1998, Vadym Petrovych Hetman, who at that time headed the exchange committee of the Ukrainian Interbank Currency Exchange, was killed by six shots in the freight elevator of his house. Hetman made a huge contribution to the formation of the financial system of Ukraine and gave Viktor Yushchenko a way to life, and his death determined the second term of President Kuchma.
On April 22, 1853, Alphonse Bertillon was born in the family of a doctor in Paris, who was the first in the world to introduce scientific methods of work in forensics. The identification of criminals was one of the most difficult tasks of the French criminal police of Surte, so Bertillon developed and successfully implemented a system that made it possible to establish the identity of criminals with impressive accuracy using the method of identifying criminals by measuring the sizes of all parts of the body (method of anthropometric registration), signal and metric photography on the place of the event, a systematic description of a person’s appearance using special terminology (“verbal portrait”). He is the inventor and creator of file systems for registering people according to any of their physiological characteristics with the purpose and possibility of using these files for identification and identity establishment.
In addition to photographs and measurements, Bertillon developed a precise method of documenting crime scenes through photography. He mounted the camera on a tall tripod to record and examine each scene before investigators began their work. Bertillon’s system lasted about 30 years and was superseded by fingerprinting.
On April 22, 1724, Immanuel Kant, the founder of German classical philosophy, was born in the city of Königsberg (now Kaliningrad), who is considered the most influential thinker in modern history.
