If you have
A = C, then we know, as A gets bigger and bigger, so does, C, and as A gets smaller, so does C.
And if you have (below as fractions).
A C
- = -
B D
Then as A gets bigger, so does C, and as A gets smaller, so does C. And as A gets bigger, B and D get smaller.
But what if you have.
A/B = C, and A = C/D, can you draw conclusions on "the bigger and bigger A gets, does C get bigger or smaller?" Or do mathematicians say not definable? 67.175.224.138 ( talk) 08:48, 17 October 2019 (UTC).
bigger (grows larger in magnitude)" was intended to apply to all uses of "bigger" and "smaller" -- that is, they grow or shrink in absolute magnitude. Perhaps I should have been clearer, and also stated that those values which shrink in magnitude do not change sign, and that no values are zero.-- ToE 19:01, 17 October 2019 (UTC)
Here's an example of concepts found in several sciences: water travels from high concentration to low concentration, gases travel from high pressure to low pressure, and electricity travels from high voltage to low voltage. Can anyone think of a 4th? The 3rd 1 is the most abstract to me, voltage is ultimately another word for "pressure." This prolly falls under a concept of spontaneity. 67.175.224.138 ( talk) 19:57, 17 October 2019 (UTC).
Heat flows in the direction that will cause an increase in entropy. Dolphin ( t) 03:31, 18 October 2019 (UTC)
Okay here's another concept, which is like a lack of imagination. I kind of categorize it "people who think like minimum wage employees and people who don't think like minimum wage employees." I walk into a Dunkin Donuts order a small hot chocolate. 3 cup sizes. When they out of small cups, a young female employee will use a medium cup, but not fill it all the way, say, ~80% full, but still charge it as a small cup. (Or if out of small and medium cups, use a large cup, but fill ~60% full). Then 1 day, with an old guy employee, they were out of small cups so he asks me to buy the medium cup instead, for X more cents. I said no thanks and takes off, and he still says to me "medium cup, only __ more cents." And he's someone who could have worked with Dunkin' for years, and still doesn't think of this idea. The interesting thing is, I tried sending an e-mail to corporate Dunkin' if there is a policy against this situation: if you're out of small cups, can you use a medium, but still charge it as a small cup, but not fill as much? I asked if there was a corporate policy, and so these employees are secretly not caring, or is this policy dependent on the individual store (up to the store manager). And they responded back avoiding the question. Sigh. 67.175.224.138 ( talk) 03:52, 21 October 2019 (UTC).
