- Comment on UwU brat mathematician behavior 5 days ago:
An Integral is usually written like ∫ f(x) dx or alternatively as df(x)/dx. Please note that this is just a way to apply the Operation Integration, like + applies the Operation Addition. There is no real Multiplication or Division.
But sometimes you can take a shortcut and treat dx as a multiplied constant. This is technically not correct, but under the right circumstances comes to the same solution as the proper way. This then looks like this ∫ f(y) dy/dx dx = ∫ f(y) dy
Another thing you can do is to move multiplicative constants from inside the Integral to in front of the Integral: ∫ 2f(x) dx = 2 ∫ f(x) dx. (That is always correct btw)
What anon did was combine those two things and basically write ∫ f(x) dx = dx ∫ f(x). Which is nonsensical, but given the above rules not easily disproven.
This is more or less the same tactic used by internet trolls just in a mathy way. Purposefully misinterpreting arguments and information, that cost the other party considerably more energy to discover and rebut. Hence the hate fuck.
- Comment on Germany | Major evacuation in Cologne after second world war bombs discovered 1 month ago:
Bombs in WWII were both inaccurate and relatively unreliable. Something around 10% of Bombs dropped didn’t explode and of those that did explode only ~5-10% did so on target.
The answer was to just drop more bombs, increasing the amount of duds even more. Roughly 2.5 million tonnes of tnt equivalent were dropped over Germany alone, mostly in 50kg to 500kg packages.
Additionally factors like muddy grounds both increases the chance of malfunctioning trigger mechanism and the bomb simply burrowing into the ground, hiding from visual detection.
I leave you with the math on how many duds are potentially buried.
To me it is a form of memorial on why war, especially large scale war, just sucks. Society still has to pay the price of the actions of people that are mostly dead by now. And I’m scared that more and more people in the world want to revive the ideology behind those actions.
