### On the connection between science and reality

My question is basically targetting various sciences that we use to understnad the real world and how we form laws in them. For example, in physics, we first see sometthing in the real world. Let it ...

### Is this metalogical diagram a reasonable presentation of untyped logics?

Diagram 1 represents my attempt to present the main components of classical predicate logic in a simple diagrammatic form. Diagram 1 is about logic, not in a particular logic, hence the term ...

### Is the notion of "Complex System" a philosophy of science? Is it the opposite of Reductionism? Is it related to Holism?

I have tried to come to terms with the notion of "complex systems" of which I heard in one of the lessons at school though without too much depth. I grasp that a complex system is such that ...

### Philosophy of science: Determinism and indeterminism in statistical methods of science

A variable is modeled as a random variable in a statistical model, often without reference to the question of whether it is random in reality. For example, when the outcome of a coin flip is modeled ...
