@Gąska Wait, have those guys never heard of preservation of angular momentum?
-
@Rhywden The system is not independent and the Earth can soak up a lot of angular momentum.

As much as we all love to cling to 19th century science myths, preservation of angular momentum is NOT the reason bikes work.

There's no to epsilon net force on the axis of the Earth, it was all lost within meters of the bicycle.

Looks to me like it does, their mathematical prowess nonwithstanding. The faster the wheels spin the more stable - that's a pretty strong sign that this law of conservation is involved.
Sometimes stuff is weird - like the fact that high tide can be seen on the near and and the far side of the Earth relative to the Moon. Doesn't mean that gravity does not play a significant role.

Small steering reaction forces are doing a fair bit towards uprightness there. Some of these are pushing off of the angular momentum. The front wheel is much harder to reason about than the back. Back wheel probably contributes some gyroscopic stability more directly.
Of a bicycle. Less applicable for the Moon.

Conservation is involved, but just like the Bernoulli principle and airplane wing lift, it doesn't explain enough of the situation (at least from what I've read, which isn't all that much). Conservation of angular momentum explains a small percentage, leaving the rest mostly unexplained (again, from what I've read).

Having nerded out on motorcycle design and manufacture, the stabilization of a single track vehicle like bikes is due to a bunch of factors, and not one main factor. Geometry, gyroscopic effect and mass distribution among other things make it all work. There is plenty of nice formulas for the design of motorcycles and what any change in the design will have as an effect on the behavior of the vehicle, so I'd suspect there are for bikes as well.
-
@Carnage in the video they say that a research team designed a bike in such a way that every factor that's thought of as contributing to bike's stability is cancelled out, and the bike still worked. So I guess it's kinda like quantum physics - we have a very good idea what is happening, but we don't have a slightest clue why.

though known to be a hoax, became celebrated as a successful example of surrealist poetry in their own right, lauded by poets and critics
-
Paradoxically, that's actually proving the hoax author's point beautifully (i.e. that those poets and critics are desperate to believe bullshit, even when they have definite proof it's bullshit).
-
@Zerosquare said in TIL (about the Dark Arts of HTML):

Which would be fine… except this is basically the hoax authors' only long-term notable work.
-
That doesn't mean much. There are plenty of people who have had a long career, but whose fame is mainly for something that's only a small part of it (or even only tangentially-related to it).

Sure but how many poets in total across the entire history of the world have even one work that's "long-term notable"? 0.0001%? Are you really making an argument that not being in the top 0.0001% of the world makes the author a failure?
I realize you were just joking and I'm in the wrong for taking you seriously. But I really really hate this attitude that if you're not literally #1 in the world, you may as well not try at all. I have no idea how good their other poems are, and neither do you. I have no idea how successful they were in their time, and neither do you. But just the fact those other poems aren't part of a standard school curriculum like Shakespeare or The Great Gatsby, isn't enough to say that they weren't good.

I liked it (the new one). I knew nothing about the novel before watching it, so I had a few surprises.

I can't say I'm any wiser but it's fairly interesting.

Considering the world has a population of 7.594 billion as of 2018, it's incredible to think some countries don't have a population of over one hundred million people.
It's only incredible if you've either a) done math or b) live in a country where there are over one hundred million people†
† Which turns out is a minority of them, but it does include the US which is why it is incredible to them (it surely isn't because they've done math).
-
@Zecc Yeah, there's what, 180 countries?
That puts the average at 42 million. Removing the largest outliers (China and India, good for about 1.4 billion each) lowers the average of the rest to 32 million.
-
@DogsB TIL that scrap spherical cows, there's an absolutely gigantic square cow in the middle of the US.
-
@PleegWat I wasn't even considering "7 billion" is 7000 millions, not 7 million millions.
I think I've read the world's population being "~7 billion" so many times I've sort of archived it in my mind as being 7 long billions and not 7 short billions.

And then there's that. I'm usually a long billion guy but I know world population is in the milliards not the long billions.

We crossed the 7 billion mark in 2011. Now we're almost at 7.6 billion.

Like "New Zealand is small compared to the United States" (actually they do say "it's no surprise that...")
Especially if you're already comfortable with the idea of Australia being roughly the size of the United States, and the fact that New Zealand is right next to Australia.
