This device for measuring the coordinates of celestial bodies was invented by a female scientist, philosopher, astronomer and mathematician Hypatia of Alexandria in 370 BC, when people believed that the Earth was the center of the Universe. The astrolabe is sometimes called the first computer, so many features of this complex device. With this unique tool it was possible to determine not only the latitude but also the altitude and azimuths of the stars or the Sun, the moments of sunrise and sunset of light, to solve purely earthly tasks, like measuring the depth of the well or the height of a terrestrial object, calculate trigonometric functions do conversions between three coordinate systems, and more. Knowledge of astronomy was considered the basis of education, and the ability to use the astrolabe was a matter of prestige and a sign of appropriate education. European masters, like their predecessors, the Arabs paid great attention to decoration, so that the astrolabe became the subject of fashion and collecting in the Royal courts.

Pink champagne

This has significantly improved the quality of the drink and have led to this success. Pink champagne is always more expensive than white counterparts at least twice. This is due to the complexity of the technological process: in the production of this drink can not "hide", "cover up" the shortcomings and mistakes of the winemaker. Besides pink champagne is usually aged longer than their counterparts ― it simply is kept better than others. In the end, pink champagne is considered a lot of aesthetes, connoisseurs of subtle, complex taste.

Periscope for submarines

Device, allowing sailors to determine the distance to observed objects, in 1845, patented American Sarah Mather. The prototypes of periscope existed, but this woman has perfected the instrument.

A periscope for a submarine was first used in the United States during the civil war of 1861-1865, and in the First world war soldiers mounted periscopes to the trunks of guns, that allowed the arrow to be in the trench and at the same time to fire.

Canned meat

In ancient times it was done drying, drying, and Smoking, and in the 18th and 19th centuries came the way of canning using sterilized. This has contributed to the scientific arguments of the two scholars, the Irish Nedgame and the Italian Spallanzani: the first claimed that microbes arise from non-living matter, and the latter asserted that each microbe has its own progenitor. This led to the revolutionary idea that the products hermetically-sealed and subjected to heat treatment, can be stored for a long time. The only disadvantage of this method of food storage was that at the time of such manual processing was quite expensive, and the containers weighed a lot more content: before the invention of cans of food tin was far away.

Going to another secular party, Mary noticed that the corset of thick fabric can not be combined with her gorgeous evening dress, opening the back, and a couple with their maid made of two elastic bands and a pair of handkerchiefs "bra back". Miracle linen was loved by many friends family Jacobs and eventually became very popular. Not surprisingly, after a few years the rights to the invention were purchased by Mary Phelps, a major firm engaged in the manufacture of corsets, for the fabulous for those times the sum $ 15,000.

Marion Donovan received a patent on this, but big business was not yet ready for such advanced ideas. As a result, she sold the patent for $1 million manufacturer of children's clothing Keko Corporation (which also has not been particularly successful). The success of her invention is achieved only when they are interested in all well-known company Procter & Gamble in the late 50-ies.
