By the time it's a pepper, it's got fertilised seeds in it. How is that going to be "male" in any traditional sense? https://www.snopes.com/fact-check/gender-pepper/

Light case vs heavy case: protection from shock transfer
John Cuthber replied to StringJunky's topic in Engineering
Sorry to hear about the guitar. For the record I'm a Bloody chemist. -
natural phenomena should be not named after people
John Cuthber replied to Alex Powell's topic in General Philosophy
As far as I can tell, the OP is on about "things" rather than units. Essentially all names of things- gravity, electricity etc- are arbitrary. Using the discoverer's name is as good an arbitrary choice as any. The name of barbituric acid is, at least a bit more interesting "There are several stories about how the substance got its name. The most likely story is that Baeyer and his colleagues went to celebrate their discovery in a tavern where the town's artillery garrison were also celebrating the feast of Saint Barbara – the patron saint of artillerymen. An artillery officer is said to have christened the new substance by amalgamating Barbara with urea.[25] Another story holds that Baeyer synthesized the substance from the collected urine of a Munich waitress named Barbara" (From WIKI) -
Light case vs heavy case: protection from shock transfer

OK, so I solved the problem for a spherical guitar, and Bender solved it for the case where you only drop the guitar (and case) in a muddy field or above a vat of cold porridge. I wonder which of those is less use. -

OK, So when they discovered Brownian motion, they didn't know what it was. How could they classify it? What would they have called it in the mean time? So, your suggestion seems to be unwieldy, and solves a non-problem. Why bother with it? -
Light case vs heavy case: protection from shock transfer
John Cuthber replied to StringJunky's topic in Engineering
Shock waves are unlikely to pass efficiently from a dense material to a less dense one. However, the fundamental question isn't well specified. Imagine getting a hollow wooden ball enclosed in a layer of aluminium foil. If you drop it, it will get damaged. Imagine putting it in a thick metal sphere + dropping it. Well, it might protect the wood, it might not. Certainly, if the metal gets dented it wile damage the timber. If the metal is thick enough it will survive intact but, even if it does that doesn't guarantee the safety of the wood, because the metal will flex during the impact.. If you put a layer of foam between them then, if the foam is thick enough to take up any flexing of the metal then the wood will be fine. In that case the weight of the metal is not very important. -

Yes and no. There's more damage done, but not to the guitar. Ask the people who make tanks for the army. -
Eric the God-eating penguin is a perfectly possible notion, and proves the non-existence of God.

I'm 52, how old are you? Also, no matter whether you think it's childish or not, the logic is correct.
-
Like it matters... Does God know what question He can't answer? And also, here's my favourite proof about God. "God can't exist because of Eric The God-Eating Magic Penguin. Since Eric is God-Eating by definition, he has no choice but to eat God. So, if God exists, He automatically ceases to exist as a result of being eaten. Unless you can prove that Eric doesn't exist, God doesn't exist. Even if you can prove that Eric doesn't exist, that same proof will also be applicable to God. There are only two possibilities - either you can prove that Eric doesn't exist or you can't - in both cases it logically follows that God doesn't exist."

Has the Republican party lost its collective mind?
John Cuthber replied to Moontanman's topic in Politics
With a vote of 52:48 Brexit very nearly didn't happen. Russia interference may have made those few percent difference. -

As far as I can tell, it's not a caricature; it is mainstream policy. -

Congratulations! You are half way to understanding why God is not omnipotent. Once you realise that things like logic and maths make omnipotence impossible you will realise that it's not "mathematics is excluded from omnipotence"-(it can't be by definition) but that mathematics is excludeds from omnipotence. The concept is self-contradictory. Only the God-squad still buy into it.
-
No, That's part of omnipotence. Omnipotence is the ability to do everything. It kind of goes with the territory of that being what the word means.

Ah yes- the old ones are the best. Rugby: a game played by gentlemen with funny shaped balls.

My friends have learned to say no when I ask if I can look at their CD collection... Incidentally, non explosive reactive armour also exists https://en.wikipedia.org/wiki/Reactive_armour#Non-explosive_and_non-energetic_reactive_armour and in some way, it actually answers the OP's question about turning the attackers blow against themselves. As the wiki page says " This is almost the same as the second mechanism that explosive reactive armour uses, but it uses energy from the shaped charge jet rather than from explosives"

On a related note, if you break a half silvered mirror, do you get 3 1/2 years' bad luck?

I think you are talking warlocks.

That's interesting. Mine went purple. But it was Sensei I was referring to.

And you didn't understand that I do that by walking away. You should get a mirror.
