Where was germanium discovered? How was nobelium discovered? When was evaporation discovered? When did Antoine Lavoisier discover carbon? When was the electromagnetic force discovered? When was the synchrotron invented? What year was platinum discovered? When was the periodic law created? Where was gal...
Dimitri Mendeleev is an iconic figure in the field of chemistry. The Russian inventor born in a low-income family and lost his father at a tender age invented the periodic law and formulated the earliest edition of the periodic table.
The periodic table was invented by Russian chemist Dmitri Mendeleev in 1869. However, prior to Mendeleev, chemists had been pondering for decades how to classify the elements. Beginning in 1789, Antoine Lavoisier began classifying elements by their properties. Johann Wolfgang Döbereiner showed in ...
But our Moon is different. Its orbit doesn’t lie in the plane of the ecliptic. Instead, it’sinclined at about 5°. (How it got that way is unknown, but it’s presumably related to how the Moon was formed.) But that 5° is what makes eclipses so comparatively rare...
During the sixteenth century, astronomy was the field in science which could be perceived as the pivotal field where traditional forms of seeking for knowledge were questioned and the principles of modern science were developed. The main reason was that observation (of the movement of the stars) ...
It is always interesting to study the influence of a well-localized impulse-like source; therefore, we tried the Lorenzian form and luckily found highly non-trivial solutions. As a second interesting system, the effect of periodic driving was investigated. It looked logical that for a traveling...
Before modern metalworking techniques were invented, blacksmiths used heat to make metal workable. Once the metal was formed into the desired shape, the heated metal quickly was cooled. Quick cooling made the metal harder and less brittle. Modern metalworking has become much more sophisticated an...
However, the machines do not adapt. Once built, the water hammer will rise and fall under the influence of the neighboring river. It will not work to turn it into a drilling machine for half an hour, even if it is very necessary. The answer to this inconvenience was computers — program...
