Mach-E was the bestseller last month, second place this month after the Model Y. The 80% last month were for plugin vehichles including plugin hybrid (64% battery electric, BEV), the 70% now are BEV (about 88% plugin). The numbers change a

Sounds to me very much like "I want to learn truths and relationships about natural language that are independent of any specific culture and history", i.e. independent of any particular language and concepts like alphabets and sp

For me, the photos in the linked article look great no matter what the process was to create them. I don't see why they would lose their charm if they were CGI, simply because we tend to know whether we like a picture or not within a s

Quoting the article: "While a few other substances (like solid neon) could potentially explain the coma-free acceleration, hydrogen was the best match for the data." It doesn't have to be hydrogen. But to explain acceleration

Not all that massive: 6% increase if all cars and vans (excluding e.g. big rigs and tractors) go electric, according to the Norwegian national grid institute[1] (in Norwegian). Some local grids will need an upgrade, but the national transmi

Because for a given amount of funding and engineering effort, a telescope on the ground can be a lot larger. Hubble has a 2.4 meter mirror, TMT is 30 meters. Resolution scales with the diameter of the mirror (so an order of magnitude more f

Have a look at dry plate and wet plate photography. Dry plate is silver and gelatin on a glass plate. https://unblinkingeye.com/AAPG/DPlate/dplate.html The primary difference to film is that the glass substrate is

With higher resolution sensors, small imperfections are more visible. To extract the most from a high-megapixel camera, you need spot-on focusing, a higher quality (more expensive) lens, and more care (e.g. higher shutter speed or tripod) t

Probably an RTG [1], it's what NASA normally uses. It's thermoelectric [2]: Heat (in this case from radioactive decay) is converted directly into electricity without moving parts. [1] https://en.wikipedia.org/wiki&

As a web/game developer, you forgot to include the OS and the drivers in the lines of code involved in executing the stuff you are writing. The Linux kernel was 15M lines in 2013 [1], more than half of that was drivers. Windows XP was

Massive in extent, it covers large parts of the planet, and in duration, could last for weeks or months. The threat to Opportunity isn't that the storm could rip it apart. It's that even a low-pressure wind can lift a lot of fine

Presumably the launch date, Intel lists launch dates for all of their processors on ark.intel.com [1] 5 years is Haswell, so Haswell and newer should get the microcode fix. A 3 year old computer is likely to have a CPU no more than 4 years

No, it doesn't. If it did it would probably exclude Mercury and Mars, at least.

Because when Pluto was discovered, they thought it was alone out there. Then they found that Pluto was a lot smaller than first thought (mass 1/5th of our Moon, roughly the size of Australia), and that there were a lot of other objects
