He observed this eclipse in Berlin, where he moved in 1741. Here he worked in the Berlin Academy of Sciences and was appointed as head of the Berlin Observatory, and was also tutor to the nieces of King Frederich II of Prussia. Observations of the eclipse of the sun made by scientists of the day led them to believe that the moon did not contain sufficient atmosphere to provide the effects of diffraction or

Another example of innovation is disruptive innovation with the creation of the first electric light bulb. This invention explored a new technology by using a tiny metal filament enclosed within a glass envelope, and offered greater convenience and adaptability than previous forms of lighting. Carbon arc lighting evolved for public street lamps, an incremental innovation, utilizing proven technology from Davy's discovery, which helped spread the use of lighting. Another big step for lighting innovation was the patenting of incandescent filament light bulbs, by legitimizing and standardizing the
When researching the birth of the battery, textbooks will credit Count Alassandro Volta with the creation of the electric battery, which was invented in 1800. But, a great find in Baghdad is believed to discount this honor. As you can also assume from his name, the measurement of potential electric output is called the volt. Referred to as the Baghdad Battery, this artifact was discovered within the ruins of a Parthian village, which is estimated to date back to between 248 B.C. and 226 A.D.
Although Ben Franklin created the idea of electricity, electricity is used quite different today. Created in 1752, Franklin used his famous kite experiment and proved that lightning was electricity. Currently, we don’t use a kite and key to get electricity, we have electric companies that distribute it out. Admiring Ben for what he did gives people the inspiration to invent new things! Ben Franklin the person who discovered electricity will be remembered in American History.
He was born in Poland in 1908. His family suffered great hardship in the first world war but he was exceptionally intelligent and determined, and managed to become a nuclear physicist. After the invasion of Poland, he came as as a refugee to England to work with James Chadwick at Liverpool University. He then went to Los Alamos, New Mexico, as part of the British contingent involved in the Manhattan Project to make the first atom bomb. In his mind there was only one justification for the bomb project: to ensure that Hitler did not get one first.
6. Is it possible to light a candle without touching the flame directly to the wick? Why or why not? Materials • candle • matches • safety goggles • lab handout & pen • ruler • watch glass • 400 mL beaker • CO2 indicator solution (limewater) • 50 mL beaker (for indicator) Procedure My lab partner and I performed a series of experiments to investigate the chemistry of the burning of a candle. The teacher provided the following chemical equation to describe the burning, or combustion, in the candle: Hydrocarbon fuel + O2 ( CO2 + H2O The candle we used was a small, white emergency candle about 3.5 cm tall.
The flame throwers used a piston system to pump a sort of gasoline like substance out of a tube. At the end of the tube was a candle which would ignite the fuel. These made Chinese fortifications almost impenetrable until the Mongol invasion. The fire lance was the precursor to the gun. It was a short iron tube with a tiny hole at the end for the fuse.
I visited the Griffith Observatory on Sunday November 16, 2014. During my visit I was able to observe the Tesla Coil demonstration developed by the late Nikola Tesla. Mr. Tesla designed the coil to someday transport electricity by air wirelessly and free. The energy would come from the magnetic field and atmosphere producing high-voltage, low-current, and high frequency alternating-current electricity. He had some success in his research but investors found it impractical and refused to support further research.
Franklin used a kite to verify the connection between electricity, and lightning. Other famous inventions that Benjamin Franklin created were the bifocals, the glass armonica which was a musical instrument, and swim fins. Another Invention of Franklin’s was a heat-efficient stove. This stove was created to heat homes efficiently. Benjamin Franklin the Politician Benjamin Franklin’s interest peaked in the 1750’s.
