Heliocentricsm
An astronomical model that depicted the sun at the center of our orbit, rather than the earth, which was the belief at the time. The idea that Earth revolved around the sun as early as the third-century bc, but it wasn't until Nicolaus Copernicus created a scientific model that the idea began to gain traction. -
Galileo's Leaning Tower of Pisa experiment
Galileo was said to have dropped two different objects of different masses at the same time and proved his idea that the rate at which objects fall isn't dependant on their mass, and disproved Aristotle's theory of gravity. -
Pascal's Law
Pascal's Law is a principle in fluid mechanics crated by Blaise Pascal. It states that a pressure change at any point in a closed incompressible fluid is balanced throughout the fluid so that the same change happens all throughout. -
Newton's Laws of Motion
Newton studied mechanics quite closely, and came up with three basic rules about mechanics:
* Every object in a state of motion will remain in motion unless an external force acts on the object.
*F=ma where f is the forces, m is the mass and a is the acceleration.
*For every action there is an equal and opposite reaction. -
Kinetic Energy
Thomas Young came up with the idea of Kinetic Energy, the amount of energy an object has due to its motion or movement. -
Doppler Effect
The Doppler Effect hypothesis was made and ten experimented by Buys Ballot in 1845. He confirmed that the sound's pitch was higher than the outputted frequency when the source of the sound came closer to him, and lower than the frequency when the sound source moved away from him. -
Albert Einstein and Special Relativity
Special Relativity is the concept that the speed of light is a factor to any observer. (I THINK, this theory is really complicated.) Einstein then came up with the famous equation, e=MC^2, to help explain and prove the idea that the speed of light affects the observer, hence the title special relativity, it's relative. -
Neil Bohr created the Bohr model of an atom
At the time of its creation, there was very little knowledge about what an atom might look like. The Bohr model suggested the idea of small orbitals around the nucleus and was one of the very first detailed models of an atom. -
Big Bang
The Big Bang theory and model depicts how our universe initially expanded from its start of high density and pressure. In 1931, Lemaître suggested that the further in the past the smaller the universe was, until at some point in the past the entirety of the universe was concentrated into a single point in space, before the expansion. This theory is often used to express the beginning of life itself. -
The first image of a black hole is released
Horizon Telescope finds and snaps a picture of a black hole. The image provided a test for Albert Einstein's general theory of relativity under harsh conditions. Although many had ideas about what a black hole could look like until 2019 we had never actually seen one.
