in the 2005 hsc theres this question about how pauli and Fermi contributed to the neutrino and in the markers notes it says many didn't mention what Fermi did. Fermi simply stated that the so called neutral particle that Pauli suggested should be called a neutrino, so that it wasn't confused with the neutron, right? or was there something else he also did.

Also when talking about what Heisenberg contributed, the success one textbook talks about some matrix mechanics stuff that he did, what the hell is that? Only ever learnt about him developing the uncertainty principle

What are we expected to know for the hsc? Are we even supposed to know that for the hsc? Is simply saying, "Heisenberg developed matrix mechanics to explain quantum phenomena, that is similar to Schrodinger's wave equations, to further our understanding of the atom" in a typical HSC question good enough?

Don't know, depends on how many marks it's worth. But it's best to know as much as possible so you can add in as much info as you think necessary. Just memorise the info above.

Iirc, Fermi noticed that when a neutron underwent radioactive decay to form a proton and an electron, the initial momentum was not equal to the addition of momentums of proton and electron, which would violate the conservation of momentum. Thus, there must've been another particle that was undetected, which carried away the remaining momentum, which was the neutrino as suggested.

Iirc the textbooks are good for this section. Add together the sample answers from the Odlum book and you should have enough stuff to memorise to be able to answer Q's on this topic (at least the typical questions, even if they're long markers).
