Through this reconstruction, he discovered that sets of points could be used in geometry by using a coordinate plane.
-
When studying various curves, he stumbled upon an algorithm that is the equivalent of what we know as differentiation, or derivatives. This occurred in the mid 1630s.

Fermat's Last Theorum was published after Fermat had passed, puzzling mathematicians for years to come. -
Fermat developed another theorem, his Little Theorem which is also known as number theory. -
Fermat and Pascal worked together on probability theory, they wrote letters back and forth discussing the issue in depth (and way passed my understanding of probability). Link to letters: https://www.york.ac.uk/depts/maths/histstat/pascal.pdf

Fermat's Principle in optics relates to light. He found out that light takes the path of least time.
-
After Fermat had passed, his work titled Introduction to Loci was published. This work includes the fundamentals of analytic geometry.

Johannes Purkinje discovered the first nerve cells, known as Purkinje cells. These cells are noted for their extreme dendritic branches. -
Otto Friedrich Karl Dieters published the first drawing of a neuron, depicting the nucleus, axon, and multiple dendrites. -
This theory, proposed by Joseph van Gerlach, stated that the nervous system was composed of a connected network of cells, with no synapses.

-
Vilhelm von Waldeyer decides to call the nerve cells that they were looking at in the brain, neurons, which is what we all know the cells in our brain as.
-
The Neuron Doctrine is the opposing theory to the reticularists. It states that the brain and nervous system is made up of individuals cells that have gaps.
-
The Neuron Doctrine comes out as the agreed theory of our nervous system development, with strong evidence for the presence of synapses
-
In the 1960s, neuroscience was known as a branch of science relating to the study of our brain and nervous system.
