Who Discovered Hydrogen?
Known as an odorless, colorless and nonmetallic flammable gas, hydrogen is one of the most abundant elements in the universe. This element is important to the formation of stars belonging in the main sequence. However, the gas is very rare in our planet. The chemical element has various industrial uses. Moreover, the element is important to the discovery of the atomic structure. To learn more about this element, it is best if we start with the history of the discovery of hydrogen. Historical Background Who discovered hydrogen? Henry Cavendish discovered the element in 1776. He found out that various elements including hydrogen composed water. Cavendish also discovered the gas from a certain metal-acid experiment that he performed. Antoine Lavoisier named the gas hydrogen in 1783 when he and Pierre-Simon Laplace proved the findings of Cavendish that water could be produced when the gas is burned. The element was first liquefied in 1898 by James Dewar. He did this with the use of a vacuum...

Who Discovered Jupiter?

Who Discovered Jupiter?
Jupiter is among the five planets in our solar system that are visible in the night sky. You can observe this planet without any aid from binoculars or telescopes. Because of its night time visibility, we know that this planet has been seen by people even before anyone has ever recorded history. Because of this we can’t really tell who discovered Jupiter. The planet has always been known even in ancient times. It has also been observed for thousands of years by many different people. Galileo’s Discovery Jupiter was observed by Galileo Galilei on January 7, 1610. Not only was he able to discover the planet he was also able to discover three of the many moons orbiting it. On January 13 of the same year, which is only six nights after, he discovered a fourth moon. The four moons were later dubbed the Galilean Moons. All the moons were named after the lovers of the god Zeus. However, even after Galileo’s discovery we may not credit him as the astronomer who discovered Jupiter. Challenge...

Who Discovered Fireworks?

Who Discovered Fireworks?
Who discovered fireworks? The Chinese discovered fireworks and gunpowder about two millennia ago during the Sung Dynasty. A popular story tells how a cook stumbled upon it when he unintentionally mixed sulphur, saltpeter and charcoal. The mixture was combustible: it burned and when stored in a bamboo case exploded. This may be considered the first fireworks ever made. But not for the same purpose as fireworks are now used—in celebrations. The Chinese had a more urgent issue to deal with. They built rockets powered with this new powder and used them well against the Mongols in the 1200s. A thousand years later, another Chinese man discovered he could make firecrackers. This time it was a Chinese monk from the city of Liu Yung, in Hu Nan province. The monk’s name was Li Tian. His achievement was so significant to the Chinese that they built a temple for him during the Song Dynasty. Since then, the Chinese have been celebrating the discovery of fireworks on April 18 by making offerings...
