Flightradar24 had a notification that the Concorde was flying again, first thing I saw this morning and I completely fell for it.
Not knocking people’s choices, it just wasn’t for me. If math in reality isn’t math in education, it’s even better that I left.
I’ll still contend math is much more elegant than physics or engineering, though. There’s no e^I*pi + 1 = 0 equivalent for either.
Respect. Physics is way up there in terms of hard science nerd cred.
Eh, it’s just fundamentally ugly to me and that really turned me off. Rounding doesn’t help, that’s like turning the lights off for sex to make it better. I still know the ugliness exists, even if I don’t see it.
Engineering is still very cool to me, and I have huge respect for those who do it, but I’d never have made it. It’s physics but even further perverted by reality. Math was beautiful to me because of how “pure” it was. Just straight logic, divorced from the messy world we live in. Tidy coefficients and elegant derivations.
Numbers like that are why I quit majoring in mechanical engineering. Physics took the beauty of math and made it ugly.
You knew something was wrong in calculus when you got a fucked up coefficient that wasn’t a nice number.
Spun is also fucked up on hallucinogens, like at a festival when you take too much acid.
You didn’t discover this as a child? Shit, spinning around was the first high I ever had, followed a few years later by hyperventilation.
I know you said read, but the reason this came to mind was from rewatching an excellent Down The Rabbit Hole video recently. It’s a good one, 24 minutes long and no annoying bullshit or filler. The concept of social density is mentioned in the video, which isn’t something I saw reading the wiki on it or during a quick search.
Side note, these experiments are what inspired the Rats of NIMH books which you may be familiar with.
Makes me think about the concept of social density in the mouse utopia experiments. It wasn’t population density per se that caused the decline of the mouse society, it was the inability to escape social situations.
Fantastic post workout snack, hydration and high quality protein.
Using an ATM to get foreign currency is still insanely better than using a currency exchange place like you see in international airports. Talking 1-2% fees versus 15-20% or higher.
I think it’s kinda dumb, much like putting whole little tomatoes on a pizza It’s hard to get topping consistency from bite to bite and they’re likely to roll off.
Taste wise, everyone’s different, I’m not going to judge in that aspect.
it’s in the shitpost community and there’s no sources cited
I don’t follow the logic. Human teeth would be better if more children died? That “quality check” only applies if an organism dies before mating, which happens usually around teenage years for humans.
Maybe those hunter gatherers had better teeth because of what they ate. There seems to be too many other potential factors to simply pawn it off on Darwinism.
In a study published in the latest Nature Genetics, Cooper and his research team looked at calcified plaque on ancient teeth from 34 prehistoric human skeletons. What they found was that as our diets changed over time — shifting from meat, vegetables and nuts to carbohydrates and sugar — so too did the composition of bacteria in our mouths.
However, the researchers found that as prehistoric humans transitioned from hunting and gathering to farming, certain types of disease-causing bacteria that were particularly efficient at using carbohydrates started to win out over other types of “friendly” bacteria in human mouths. The addition of processed flour and sugar during the Industrial Revolution only made matters worse.
The spring imparts the same amount of energy to the marble and bowling ball. The two objects are not at the same velocity, the marble would be moving significantly faster.
The same velocity doesn’t necessarily imply the same amount of kinetic energy right?
Not at all.
E = 1/2mv^2
Since energy (E) is provided by the same spring in both cases, the energy of the bowling ball and the marble are equal. Since mass (m) is much higher for the bowling ball, the bowling ball’s velocity (v) must be significantly lower.
Air resistance will affect the marble more since it’s traveling faster. I also feel like either mass (or more likely, density) of the object matters, which would advantage the bowling ball in this aspect too.
Where are the physics nerds at, we need answers!
I think they’ll both be exactly the same difficulty to stop due to conservation of energy. If the spring used is the same for both the bowling ball and the marble, the bowling ball is going to be going much, much slower than the marble.
The same way it works in any vehicle with a motor and a transmission. The motor connects to the input shaft of the transmission, runs through some gears, and the output shaft spins at a different speed from the input shaft.
