(whisper) Hey guys, there's plenty of room for discussion in re the axiom of choice and the continuum hypothesis available elsewhere on PF; thanks for not continuing those topics here.

More like a Spoonerism... but worth a chuckle.

Yes, one can add riptides, sharp rocks, 'rogue' waves, cold water, strong currents, kelp tangles, live and dead jellyfish, oil and sewer spills, stoned surfers and boogey boarders, and sociopathic yachtsmen firing guns near shore to the dangers of open ocean swimming. ##-## @Klystron

Why don't you calculate the escape velocity of the Moon from that and check online to see whether you are right? ##-## @PeroK

Its probably worth pointing out that when engineers cheat, people die.

When Ferdinand Sauerbruch [a famous surgeon] had Max Liebermann [a famous painter] portray him, he soon found sitting too long. But the artist reassured him: "There's no other way. If you make a mistake, the green lawn will cover it up the next day. But you can see my mistake hanging on the wall for a hundred years."

It's a very good point. I remember very distinctly the Kansas city walkway collapse, and it really came down to a poor engineering decision. The original design should have been fine.

It probably helps if you click the up-arrow in the quote to see the context of his reply. :smile:

Sometimes, that's the rub. Usually though, the people they work for make a bit more money, at least for a while until the market decides your product sucks or the regulators and lawyers find out.

Hence the quality/safety problem that isn't uncommon in engineering: Do I quit, or do what my idiot boss wants? This is often an extremely complex and subtle issue. No ethics class will give you the answer to your particular dilemma. Other times it's not a dilemma, you might be clueless working beyond your expertise, à la Dunning-Kruger.

Are the engineers that designed the Ford Pinto worse than the engineers that designed the Toyota Corolla? I think probably not, they just worked for different people.

You have one of those energy efficient bulbs that take a while to brighten?

Beautiful girl (PhD candidate) working at coffee shop counter: My idiot boss.
Police: Why did he call the Police?
Beautiful: Because he's an idiot.
CPD: Tell your idiot boss don't call the Police unless he has a good reason.
BG: Well, I'll tell him, but I don't think he'll listen.
CPD [Leaves without comment]: (maybe a bit of a harrumph).

Mass is constant in a closed system. But in an open system where stuff can come in or out, it manifestly isn't constant, as the example of a person eating shows. ##-## @Ibix
