5 inventions that changed the world

Gasoline

Without gasoline, there would be no transportation industry as we know it today

Gasoline is a transparent liquid of petroleum origin that is used as a fuel in internal combustion engines. Interestingly, gasoline was initially discarded as an unwanted by-product.

Prior to the discovery and commercialization of gasoline, the preferred fuel was a mixture of alcohol, usually methanol, and a turpentine called camphene, and later this would be largely replaced by kerosene. The first oil well dug in the United States, in 1859, in Pennsylvania, processed oil to produce kerosene. Although distillation also produced gasoline, it was considered a by-product. The distillation refining method yielded only about 20 percent of the gasoline when refining crude oil.

However, once the combustion engine was found to work best on light fuels such as gasoline, the cleaning process was greatly improved. In 1913, a technology was developed for the production of gasoline using chemical catalysts and pressure. The new cracking process has doubled refining efficiency and made gasoline refining more practical.

Railways

Railways allow you to comfortably transport a large number of passengers, as well as transport heavy loads over long distances. Despite the fact that rails have been used to transport wagons since the sixteenth century, modern rail travel has a history of just over 200 years.

The first full-scale working railway steam locomotive was built in Great Britain in 1804 by British engineer Richard Trevithick. He used high pressure steam to run the engine. On February 21, 1804, the world's first steam-powered rail journey took place when Trevithick's unnamed steam locomotive pulled a train along a tram line in Wales.

However, Trevithick's locomotives were too heavy for the cast iron track that was in use at the time. The commercial emergence of railway networks took place in the 1820s. In 1821, George Stephenson was appointed engineer for the construction of the Stockton-Darlington railway in the north east of England, which was opened as the first public steam railway in 1825. In 1829 he built his famous steam engine, the rocket, and the era of the railways began.

Translation: After working for Coca-Cola all his life, Ted was notified that he was too white and no longer needed.

Then he shaved his head and sued the company for racism.

But the skin of a polar bear is black.

The first one went: a white Brit found a salary difference with a black one and sued

British police officer Matthew Parr did not want to endure racial discrimination and tried to get justice. The politics of tolerance and guilt over the years of segregation have given rise to an ugly tendency in Western society to humiliate the white population in favor of blacks. The latter triumph: they have priorities when applying for work and study, and the dismissal of representatives of the Negroid race from their posts will probably turn into talk of racism, because employers do not even risk starting this obviously unprofitable business. however, not everyone is ready to accept this situation. In Britain, police officer Matthew Parr, who worked as an inspector, found that his black colleague, Wendy Williams, received a large salary for the same job (185 thousand pounds versus 133 thousand pounds), despite the fact that he held the position even before a man. This situation angered Parr and he decided to file a complaint with the London Labor Court. According to the Briton, he is treated differently because of gender and skin color, which means there are signs of sexism and racism.

"I am a white male. I admit I get a relatively high salary. For me it is mainly a matter of fairness. I have been a civil servant for over 35 years and still have worked in organizations determined to treat people fairly. It is fundamentally unfair to pay people completely different amounts to do identical work by any measure, "Parr said in court. The Ritanian authorities denied the discrimination charge, claiming that Parr had assumed a position that now pays less than before. And if a black woman came in his place, she would receive the same salary as he did. the final decision on the court will be made within a few weeks.

"Statistics is RACISM, especially criminal"

The New York City Police Department's 2020 Crime and Law Enforcement Report reveals that 96.4% of homicides and 98.3% of non-fatal weapon use are non-whites. 33% white in the city

You won't see this breakdown in the New York Times or New York Post.

It should be noted that in New York 2020, blacks make up 22.8 percent of the population, Hispanics 28.6 percent, and Asians 12.6 percent.
