Gabriele Carcassi
Gabriele Carcassi, a physicist and software engineer, leads the 'Assumptions of Physics' project, aiming to reshape foundational physics with an interdisciplinary approach. He discusses the intricate relationship between mathematics and quantum mechanics, advocating for minimal assumptions to better understand physical laws. Carcassi challenges traditional views on gravity and explores how classical and quantum mechanics interconnect. He emphasizes the importance of experimental evidence and collaboration in the evolving landscape of physics.

Episode notes
INSIGHT

Physics Backwards

  • Physics uses point-set topology and differential geometry, starting with points and then integrating.
  • However, lab work starts with finite measurements, then reduces them, highlighting a backwards approach.
INSIGHT

Assumptions of Physics Project

  • The "Assumptions of Physics" project seeks minimal physical assumptions to re-derive laws, using reverse physics and physical mathematics.
  • Physical mathematics justifies math axioms with physical reasoning, ensuring every element has real-world meaning.
ANECDOTE

Real Numbers in Physics

  • Real numbers' justification in physics involves experimentally verifiable statements as open sets.
  • Defining numbers requires references (before, after, on), and the challenge lies in justifying their linear order.
