WARREN DE LA RUE CREATES THE FIRST LIGHT BULB

In 1840 Warren De La Rue enclosed a platinum coil in a vacuums tube and passed an electric current through it creating the first light bulb. The design was based on the concept that the high melting point of platinum would allow it to operate at high temperatures and that the evacuated chamber would contain less gas molecules to react with the platinum, improving its longevity. Although it was an efficient design, the cost of the platinum made it impractical for commercial use.

THE FIRST ATTEMPT TO KILL A SITTING PRESIDENT OF THE US

The first president that was almost assassinated was Andrew Jackson. The assassins name is Richard Lawerence an unemployed house painter. He approached Andrew Jackson as he was leaving a funeral. Richard shot a gun but it misfired, Jackson became mad and attacked his attacker. He clubbed his attacker with a cane. While they were fighting Lawerance managed to pull out a second pistol and shot it,then gun also misfired a second time. Jackson aside got Lawerance and carried him away to jail. Andrew was unharmed but very angry.

The events impacked the new American nation because everyone uses a light bulb and Andrew Jackson was the first president to almost be assassinated.

The disadvantages of the lightbulb is it takes up energy but an advantage is we have light.
A disadvantage of Andrew Jackson almost being assassinated is he was the president at that time. An advantage is it made them more aware it might happen more often.
