The Stirling Engine
Robert Stirling created the Stirling engine because he wanted to modernize boats. He also wanted to make a new, safer alternative to steam engines (At the time). The Stirling engine stores the heat in a regenerator which makes the engine more efficient. -
The Year Without Summer
The Year Without Summer was when the summer was unseasonably cold after over 1,100 years due to the eruption of a volcano in Indonesia in 1815. -
Atomic Decay
Atomic decay is when unstable parts of an atom give off energy as radiation. Jons Berzelius first discovered atomic decay in 1815 because he is smart, but atomic decay cycles (Alpha, Beta, and Gamma) weren’t officially recognized until 1896. The formula for atomic decay is:
N ( t ) = N ( 0 ) ∗ e − λ ∗ t -
The Burning of D.C.
The Burning of Washington by the British occurred in the Chesapeake Campaign of the War of 1812 and it and the American Revolution were the first times the US was both invaded and attacked (as of 2023). This occurred due to conflicts between America and Britain. -
The Stethoscope
Rene Laennec used the stethoscope to listen to the heart and lungs and proved that his diagnoses had similar results to what they found in autopsies. He did this so that we could use better and more humane ways to learn about human anatomy. -
The Electric Telegraph
Francis Ronalds invented the electric telegraph that works off electrostatic means. He did this because he imagined how our future world would use electricity instead of older versions of technology. The way he made this was by connecting 12 km of wire to different insulated wires underground, and it worked. It is a lot more efficient than a traditional telegraph at sending messages across distances. -
The Invention of the Camera
Joseph Niepce made a camera by coating a plate covered in bitumen and leaving it out for eight hours. He made the first photo and called it a “Heliograph”. He did this to make the camera obscura more effective and new; this took less time and less space and created images that were more clear.
