Who Invented Rubber Boots?

It is known that from time immemorial, the Amazonian Indians knew how to make "fast" boots: they went knee-deep into liquid latex and stood until it dries.

The boots, made especially for the Duke of Wellington in 1817 and named after him, were made of leather. The first rubber boots appeared only in 1851, a year before the death of the Duke.

At first, rubber was a real disaster for light industry: in the heat, the fabric impregnated with it melted right on the person, and in winter it became hard as a stone. The breakthrough came in 1839 when Charles Goodyear, while heating a mixture of rubber and sulfur, accidentally spilled a few drops on the stove.

Goodyear's life story is inspiring and tragic at the same time. All his life he had to fight with terrible poverty - six of his twelve children died of malnutrition - but Goodyear was simply obsessed with rubber and stubbornly did not stop trying to improve the qualities of what the inventor himself called "vegetable skin".

An accidentally discovered process solved a long-standing problem of rubber - giving it a stable consistency. Goodyear shared samples of the resulting material with Thomas Hancock and Charles Mackintosh, well-known rubber traders.

After analyzing the submitted samples, Hancock and Mackintosh were able to independently reproduce the entire process and patented it in 1843, calling it "vulcanization" - in honor of the ancient Roman god of fire. Goodyear tried to sue, but to no avail - and not for the first time went to debtor's prison, or "my hotel", as he affectionately called it.

Goodyear died without being able to get out of debt, although he earned wide recognition for his tenacity and insight. Goodyear once wrote: “Life cannot be measured only in dollars and cents. I do not intend to complain that I have sown the seeds and others reap the fruits. A person has reason to regret only when he has sown and there is no one to harvest.”

Forty years after Goodyear's death, his immortality was assured by the founders of the Goodyear Rubber Company, today's largest manufacturer of tires and other rubber products, who named their company after him. In 2005, their turnover amounted to 19,7 billion US dollars.

Random interesting fact from the Great Encyclopedia:

Why is the body warm?

To perform its tasks, the body needs energy. This energy is obtained in the process of oxidation. The fuel for this process is the food we eat. The result of this oxidation or combustion is not, of course, fire or high temperature. There are substances in the body whose task is to combine oxygen with fuel in an orderly, regulated way.

The body maintains an average body temperature of about 37°C, and this temperature is constantly maintained. This makes one of the centers of the brain, which is called the temperature center. In fact, it consists of three centers: the control center that regulates the temperature of the blood, the center that raises the temperature of the blood if it drops, the third center cools the blood if the temperature is too high.

What happens when the blood temperature drops? Part of the nervous system comes into play. Certain glands send enzymes to the muscles and liver to increase oxidation, and the core temperature rises.

In addition, the blood vessels of the skin are constricted to reduce heat loss due to thermal radiation. Even tiny glands on the surface of the skin help with this by producing fat that reduces heat loss. When the blood temperature drops too low, a shake is automatically activated. The temperature center of the brain makes you shiver to keep warm! If the temperature of the blood rises, the cooling center comes into play. It dilates the blood vessels of the skin so that excess heat escapes into the atmosphere, and sweat evaporates more easily.

Sweating is a quick method of cooling the entire body. When the liquid evaporates, it cools the place where it is located.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Junk mail is expensive 10.01.2004

"Junk" emails, better known as "spam", are not so harmless. as it might seem at first glance. According to a survey conducted by Basex, a New York-based company, the total loss of the American economy from spam this year amounted to at least $20 billion.

In large companies, the fight against unsolicited e-mail costs, on average, 600...1000 USD per year per user. It is these funds that go to the salaries of IT specialists, maintaining mail filters, paying for "extra" traffic, clearing user mailboxes and other actions related to spam protection.

It must be assumed that the indicated amount does not include the loss of working time of those unfortunates who, after all these tricks, find "junk" mail in their working mailboxes.
