    But how would that make the bowling ball fall faster? F = G × m₁ × m₂ / r² and F = m₁ × a ⇒ a = F / m = G × m₂ / r², where m₁ is the mass of the ball and m₂ the mass of the planet. So the gravitational acceleration of a bowling ball is independent of its mass (assuming the planet has way more mass than a bowling ball).

    Is there any situation where you’d want to remember the opcodes? Disassemblers should give you user-friendly assembly code, without any need to look at the raw numbers. Maybe it’s useful to remember which instructions are pseudo instructions (so you know stuff like jz (jump if zero) being the same as je (jump if equal) making it easier to understand the disassembly), but I don’t think you need to remember the opcode numbers for that.

    Edit: Maybe with malware analysis where the malware in question may be obfuscated in interesting ways to make the job of binary analysis harder?

    This one, if by unix he also means modern linux systems. Nowadays you can simply use tar xf my-file.tar.whatever and it should work on most linux systems (it worked on every modern linux system I’ve tried and every compressed tar file I’ve tried). I don’t think it is hard to remember the xf part.

    I once lived with a sort of science skepticistdenier (didn’t believe in the moonlanding nor did he believe that the earth wasn’t flat). He was of the belief that scientists are deceiving the public and one of the examples he gave was that they claim that the earth rotates at 1 670 km/h but if we look outside that’s very clearly not the case and if jump we aren’t flung at that speed to the side. I spent half an hour in a back and forth trying to explain the concept of relative velocity and inertia. It didn’t go anywhere.

    Edit: changed to denier based on the comment by logos.
