The document discusses various concepts in quantum physics, including wave-particle duality, blackbody radiation, and the photoelectric effect. It references significant experiments and figures, such as Young's double-slit experiment and Pierre-Simon Laplace's philosophical reflections on determinism and randomness in the universe. It suggests a deeper exploration of these concepts through an online course provided in the document.

6. Pierre-Simon Laplace (1749 –1827)
“We may regard the present state of the
universe as the effect of its past and the cause
of its future. An intellect which at a certain
moment would know all forces that set nature
in motion, and all positions of all items of
which nature is composed, if this intellect were
also vast enough to submit these data to
analysis, it would embrace in a single formula
the movements of the greatest bodies of the
universe and those of the tiniest atom; for such
an intellect nothing would be uncertain and the
future just like the past would be present before
its eyes.”
