Recently returned from China. The abundance of electric vehicles of all types was quite stunning. A lot of them seemed very high quality, too.

Eye response frequency depends on the light intensity. We can track higher frequencies when the lights are brighter. Dim theatres played a role in preserving the illusion of motion when movie frame rates were very low. You can also perceive

I agree. But I haven't heard a plausible geoengineering plan proposed yet. This is the part where engineers should be able to provide an answer today, achievable with our existing technology. It isn't enough to wave one's han

Thermodynamics comes into play. Because the entropy of a pure gas increases rapidly as it diffuses into a mixture, it will always require massively more energy to scrub CO2 from the air than you get from burning the carbon in the first plac

I read that because the building was directly below the bomb, the forces applied to it from the explosion were directly downwards and so the structure was better able to withstand them. Buildings farther away were hit with lateral forces th

This is an excellent article from Scientific American about a proposed mechanism for the End-Permian mass extinction, the largest in Earth's history. The author describes how deoxygenation of the oceans may have allowed hydrogen sulphi

By definition, trade secrets are not patented, as patenting requires disclosure. What do they mean by an "effort that pilfered as much as $8.75 billion in patented American technology"?

Fractions are nice when the numerator is always 1. They're a pain when it isn't; sorting drill bits or buying material from McMaster Carr, you constantly have to sort out whether 17/64 is larger or smaller than 3/8, and

If you're buying 1 milligram of a substance, how much are you affected by an one microgram error in the definition of a kilogram? Hint: not by one microgram.

Great book. Do get the most recent edition, because the recommend parts in the older ones are quite outdated.

What lengths and widths of wood can you buy from the lumberyard? What is the common width and thickness of drywall sheet you can buy and the hardware store? What door sizes are available? What size of screws are cheaply available in Canada?

Absolutely! America is very lucky to have come out on the right side of that lottery. But then it unnecessarily goes and handicaps itself by making measurements into a foreign language.

Why should there be any separation between science and daily life? Think about it not for the benefit of the current generation who would be forced to burden the switch, but for the next generation who could reap the benefits. I think one i

They aren't easier to work with for any reason other than that sizes of standard components (pipes, beams, etc) are sized conveniently in US units and have US units printed on the spec sheets. If you go overseas outside of North Americ

Is there any scale in the world that can measure a kilogram to within the accuracy of a microgram? And if you buy a kilogram of something and they accidentally short you by a few micrograms, haven't you only overpaid by a few parts per

The main obstacle is cultural. Even contemplating the building of nuclear weapons is considered a deep disrespect to the memory of the people who died in the nuclear bombings of Hiroshima and Nagasaki. There would be a lot of domestic oppos

I don't think the question is settled, but unless you really hate oranges, the cost of adding them to your diet on occasion is negligible, and the reward is either small (if they don't boost cold resistance) or large (if they do).

I'm visiting China right now; Chinese-made electric vehicles are absolutely everywhere. NIO in particular seems determined to challenge Tesla here and possibly worldwide. https://www.motortrend.com/news/nio-es8-cha

Good point. It does depend on the field though. For software, there's probably not a lot of other options. For mechanical engineering there's a lot of interesting work all over the country.

If an absentee owner is forced to sell or rent, great! If a resident is forced to sell or rent, well, they'd be either selling to a wealthier, possibly absentee owner who can afford the massive price and higher taxes, or they'd be

As a local, I would love this. They're mostly great people, and could contribute so much to the city as new Canadians. But by just buying property without actually living here, it causes lots of damage. I know several children of astro

Remember that we're dealing with property that for most long-term residents was bought fairly inexpensively a couple decades ago, on fairly low incomes, and it's ballooned in value recently. Real estate taxes are low as a percenta
