The CMA result for M343 came back with a perfect score.
Sometimes it makes sense to follow the maths and ignore your own intuition, as in the case of the one answer I really wasn’t sure of.
As for the three questions I was hopeful of, I devised another method, not described in the course notes, to check my answers.
It began by assuming a given option to the first question of the three was true and creating a quadratic in two unknowns. It relied on the correct answer being given within a range of options for the question – and was basically working backwards using proportions.
Anyway, it checked out, and immediately brought the answers to the next two.
Will continue with M343 from Monday.
For now, until Sunday night, I’m reading an introduction to quantum mechanics. Haven’t got very far yet – still pondering how Planck’s equation could have been logically derived in the first place, though I do see how it can reduce to Wien’s law and the Rayleigh-Jeans law via Taylor expansion.
