The quantum studies have strong philosophical underlying to them, in my opinion. Knowledge for the sake of knowledge (which could cover a large part of advanced math) seems to be also philosophical.
Nonetheless, if I'm looking into articles/books/content about modern philosophy, I don't really find the current scientific ideas there.
So my question is: What is modern philosophy, if it's not science?
Another major area is the philosophy of mind which includes questions such as "what is consciousness" and "does consciousness arise from matter".
Science looks for predictable facts.
Philosophy looks for ways to live will.
They're as different as chalk and cheese.
However, people do science, so, they're gonna have philosophical opinions. But you can do science without philosophy and contrawise.
Or do you mean the ontology behind science? Asking where knowledge comes from?
The whole modern materialistic scientific world view emerged from Aristotle "metaphysics" which is pure philosophy. To some extent at least.
So the more correct question is — what is modern science if not an applied side of philosophy?
