>>12877190It is not clear what you consider fundamental.
According to my understanding, fundamental knowledge is a kind of knowledge that knowing it allows you to build other knowledge on top of it.
According to me:
All of the physical constants
All normal matter is made from atoms
The periodic table
The laws of motion
Germ theory
The basics of generating electric current and what electricity is
the list goes on. tscience has evolved so far that there are too many "fundamental" things to list
