Which researchers (as opposed to pop-sci pundits) think MOND is a better explanation than Dark matter? That is a very, very fringe alt-science view that so far exists in various pop-sci blogs and informal youtube discussions, rather than in

It's worth watching the whole video! He goes over how the engine works, cooling, coupling, safety features, breaking -- really everything. Fantastic detail. In terms of being 300 more times efficient -- converting mechanical energy to

Excellent summary. It's always about opportunity cost and relative prices, because people always have options. Employees can go where they are paid more, investors can invest where the returns are higher, consumers can choose the bette

That's a very non-standard view. Animals fighting over territory is quite common even in arbitrarily small groups, so why do you think conventional thinking - that these are hardwired behaviors present in every animal from crabs to pri

> (and no, saving costs is not a justified reason) This is incorrect. Every jurisdiction allows for laying people off to reduce costs. This is the primary thing a business is supposed to do -- hire when there is more work and fire when t

This is such a foolish way of looking at public order. The point is not whether murder is wrong or whether punishing is wrong, because after all we are not children arguing about right and wrong. Rather, we need a public that is free of mur

When I think of SOMA, I think of that initial section south of market from about Spear to about 5th St, whereas the Auto Body shops are in the downtown section around 9th St and Harrison (which is a lot more walkable than the glass towers).

I always found SOMA to be quite unpleasant. Huge tall glass office towers and some residential towers that make for a poor pedestrian experience, and an even higher degree of delinquency. What makes SF charming is wooden Victorians, brick B

This is only because most people in San Francisco don't own cars. For those that do, it's quite accurate.

The alternative is to try to invade half the countries in the world. Since WW2, the US has killed over 30 million people in various military actions, and everyone of them was framed as some humanitarian action. Since 1991, we have invaded o

If you want a computer to check the tire pressure, then use a computer to poll the tire pressure indicator and report a fix error when it's too low . My 2006 Passat did that, and it didn't have a touch screen (or a backup camera)

Yes, B25026 has this data. Thanks for pointing out that the link doesn't go directly there, links to these SPAs often don't work well. FYI, S2502 is not the right table to use because it is looking at housing units rather than peo

I will respond to the one factual claim buried in all the emotional outrage. Let's look at the 2021 American Community Survey. How long someone has lived in a unit is called "tenure". You want to look at tenure for renters, w

San Francisco has a large transient population of renters. They drift in, party and work hard, and then leave when they have kids or want to settle down. This is because San Francisco is not very family friendly - it's a city with more

People also like when they can go to a coffee shop and the barista shows up, even when it's raining, and that the bags of coffee are delivered on time, and that their Amazon packages are delivered and that their local grocery is staffe

The point is that if the US is a sole producer of a good for which the rest of the world cannot produce a replacement, then it can ban sales of the good to Iran and also threaten to withhold the good from any nation unless they agree to imp

A lot of people are assuming that because the US and Europe -- e.g. the collective "West" -- is sanctioning Iran, then the whole world is, and so there is shock and confusion about how Iran can buy very common parts on the global

I think Europe is unique in terms of denying reality so much that they don't even have a plan. It's like the prospect of some things are so terrible as to be unthinkable and when something is unthinkable, you don't come up

I mean, if your hope is for regime change, then I'd recommend an energy policy that is based on something a bit more realistic. Imagine telling farmers or businesses in Germany or the UK that "Your bills will remain high until the

The high energy prices are not because of the war but because of the sanctions regime. The thing is, sanctions basically never end. It's impossible to lift them. We still have sanctions against Cuba since 1962. No one even cares abou

The idea that the US gave smallpox infected blankets to Indians is a myth that was circulating in various 1960s underground subcultures, many of which were collated and published -- without any footnotes or sources -- by Howard Zinn in his
