Well, the primary particles that hit the atmosphere are mostly protons. They cause avalanche of secondaires that are varied but mostly muons,

I'd recommend listening to Webern's Op. 27, it's a strict 2nd Viennese school 12-tone composition but also very expensive, I love it (although it works better in a concert setting then a recording): https://youtu.be/ZEtqEzPakxA?is=JgbN1lpHF1lxrXOT

Leisure only, there hasn't been commercial traffic on that canal for a long time: https://en.wikipedia.org/wiki/Union_Canal_(Scotland)

It seems to be more heat resistant?

Secondary school physics teacher here: The article is conflating power (watt or joule per second) and energy (joule or kilowatt-hour), so any claim they make is nonsense and the article shouldn't be taken seriously. My students make the same mistake all the time but they don't get to publish it :-)

Power is energy per time unit (thus: energy = power x time), so while the power of a lightning strike is very high (~10GW), the overall energy isn't because it only lasts for a very short duration (apparently the duration of a lightning event is hard to define, [1] says about 0,5 seconds, other places mention much shorter durations, ~10us). So if that 10GW lasts for 0,5 seconds, the total energy is 1,4MWh, which is 1/6 to 1/10 of the electrical energy an average American household consumes in a year[2].

I think it does:

Right at the bottom under Frequently Asked Questions:

  How much lightning would we need to capture to power the entire U.S. electricity grid?

  Merely capturing the energy from 115 lightning strikes would supply all of the U.S.'s annual electricity needs.

I believe it would be a far greater problem if those people didn't die. Aging populations are a huge problem around the globe and unless we'd improve the quality of life to such a margin that octo- and nonagenarians are able to care for each other, I think we're all better off with people dying of old age.

I work for a small company, around 10 devs. We've picked up quite a few projects over the years where a freelance team came in, built something and when the going got tough, walked away. That said, I've seen the same happen at renowned companies, so perhaps it's just an issue of generally people taking advantage of the shortage in experienced devs. I would aim to get some longer term stability, either by working with a company you trust through your network, or engage a tech Lead/CTO for a longer term who can oversee the contractors.

This should be a reliable source on 3mmc, but it is in Dutch: https://www.trimbos.nl/aanbod/webwinkel/af1916-factsheet-3mm...

I've read somewhere that the iodine can negatively affect the fermentation process, so that it's better to use iodine free sea salt. Cant remember the source, though.

Is it just me, or has DDG been having trouble often lately? Or is it just a combination with some outage + degradation of search results lately that makes me g! regularly these days? Didn't use to need that.

My mom grew up in South Africa, '40s and '50s, she always made us wash our lips after eating mango to avoid a rash. Only later did I discover I didn't need to, I always assumed the rash-causing compound has been bred out of modern mangos.
