LEGO – most famous toy

The name LEGO was made up of two Danish words – Leg and Godt, which together mean “play well.” A few years later the founder of the company found out that LEGO in Latin means “I study”.
Few people know that the most well-known toy company was started as a wood products factory.
LEGO history dates back to 1932. Ole Kirk Christiansen founded the Danish company to produce goods for daily use. All products were made of wood. At first ordinary ladders and ironing boards brought profit. But soon the global financial crisis came, and demand for these products had fallen significantly. Therefore, after analyzing the market, he concluded that even in the most difficult times the toys were bought. The factory began producing toys, and of course, the first toys were made of wood.

How people saw the future in the past

In 1900, American engineer John Elfreth Watkins wrote an article in Ladies’ Home Journal on what would happen in 100 years. Now it turned out that the author had made some interesting predictions. In particular, he was able to describe mobile phones, TV, digital photo, aircraft, tanks and even more. Nevertheless, in his article, which was entitled “What can happen in the next century,” Watkins made several predictions that had not come true.
John Watkins worked for the magazine Saturday Evening Post, which was published by the same publisher as the Ladies’ Home Journal. The editor of the historical department of Saturday Evening Post Jeff Nilsson saw an old article and decided to publish it after 112 years.

Hot Air Balloon History

Hot Air Balloon History

Hot Air Balloon History

Balloons are lighter-than-air craft that are filled with a gas or heated air. Experiments with balloon flight led to the development of the motor-powered airship and later the airplane.
Balloons can be used for advertising, scientific experiments and entertainment.
Balloons filled with the heated air are called Montgolfière-style hot air balloon. Balloons filled with hydrogen or helium are called Charles Hydrogen Balloon (however, hydrogen is now almost never used because of its explosiveness). Rozière balloon is a hybrid balloon filled with both gas and hot air.
Bags of sand are hung around the basket for ballast, or extra weight, so that the balloon does not rise too fast.
In 1783, brothers Joseph-Michel and Jacques-Etienne Montgolfier made the first successful experiments with hot-air balloon flights. A sheep, a rooster, and a duck were the first balloon passengers. The first balloon weighed 140 kg and rose to a height of more than 1.5 km.

Panama Canal – canal to link the oceans

Panama Canal is the only navigable canal, which connects the Atlantic and Pacific Oceans. It was dug through the Isthmus of Panama for ten years, from 1904 to 1914. Since that time, the sea route from New York to San Francisco shortened more than doubled, from 22 500 km to 9000 km. The total length of the channel is 81.6 km. Since 2000, the channel is owned by the government of Panama.
Oceangoing vessels that are headed from the Atlantic Ocean to the Pacific came to gateways, where they gradually raised to a height of 26 m. Then, on the waters of an artificial Lake Gatun ships sail to other gateways and come to the Pacific Ocean. After about nine hours of travelling they are in the Bay of Panama.
From 30 to 45 vessels of different types and sizes pass through the channel every day. Payment depends on the tonnage. 40 thousand tons are the maximum allowed. In total about 14 thousand ships are ferried every year.

History of telegraph


Telegraph was a wonderful instrument. Now it seems a fossil in the world of developed computer technologies. But when it was invented it was a real miracle. At first people would not believe that messages could possibly come over a wire. They waited until the mails brought the same news before they would believe it.
It was Samuel Morse who invented telegraph. He had studied both painting and sculpture and expected to earn his living as an artist. Morse tramped from town to town, painting portraits for a living for himself and his three children. However, he was thinking of different inventions. Once, Morse thought that messages could be sent by electricity and began working on his invention. He worked on it for twelve years. He also had to invent an alphabet to use in sending telegrams. It consisted of dots, dashes, and spaces.
“What hath God wrought!” was the first message sent by telegraph. By the end of the nineteenth century, most of the world was connected by telegraph lines. In 1842 Morse laid the first underwater conductor in New York Harbor.

First railroads

A railroad, also called a railway, is a type of land transportation. A vehicle called a locomotive pulls most trains. A locomotive can be powered by an engine that burns diesel fuel or by electricity.
Trains can be divided into two types: passenger and freight. The speed of many large passenger trains is about 100 miles (160 kilometers) an hour. However, some trains in Europe and Japan can go more than 180 miles (290 kilometers) an hour.
Before trains and locomotives people used horses to pull carts along tracks. In 1803, Richard Trevithick from Britain built a locomotive that ran on steam power. The railway cars were quite like stagecoaches except that they ran on wooden rails. Locomotives which breathed out steam and flame had taken the places of horses. The engine of those days had four light driving wheels and a tall smokestack. The wood, which was used for fuel, and also the water, were carried on a small platform behind the engine. As the engine had no engineer had to drive facing the winds and storms. For that reason, the locomotives were not always used in rainy weather.

History of chopsticks

History of chopsticks


In much of Asia food is usually eaten with chopsticks. Chopsticks are two long, thin, usually tapered, pieces of wood. Bamboo is the most common material, but they are also be made of various types of wood, as well as plastic, porcelain, animal bone, ivory, metal, coral, agate, and jade.
Royal families and aristocrats preferred silver ones, believing in the metal’s capacity to detect arsenic.
Today chopsticks can be made of coral, agate, jade, silk, plastic, horn, porcelain, animal bone, and stainless steel. Truly elegant chopsticks might be made of gold and embossed in silver with Chinese calligraphy.
Chopsticks may be totally smooth or carved or modeled ripples. Silver or gold paint can be used to give them a rough texture. In Thailand, wood is often elaborately carved into chopsticks. The ends of chopsticks can be rounded or squared, while the tips can be blunt or sharp.
