In medical device manufacturing you have systems in place that your vendors have to disclose changes to their manufacturing process that hopefully can catch stuff like this before people die. I can see how minute stuff gets easily passed of

I don't see why not either, just get "organic"/plant or mineral based cosmetics, deodorants and hair products.

Siloxanes contaminate everything. We routinely see them on various surfaces when doing X-ray photoelectron spectroscopy.

I've had this situation and basically just had to throw out stuff that was written because its completely terrible/wrong. Either start again or just give up.

Pausing seems more accurate. Sounds like a nice feature and if you can turn it off then no downside.

Not really new, been going on for decades. With recent political changes I would have assumed it might have been getting better actually. I'm guilty, Canadian living in the SF Bay area.

I think the materially, even pure, is strongly colored, so you can't easily determine impurities visually, unlike diamonds and sapphires and other colorless-when-pure minerals.

I think most of the commercial liquid metal like the sandisk drive were zirconium based.

Are you sure? Liquid metal was the name of a bulk metallic glass. There were usb flash drives using it as a case https://en.wikipedia.org/wiki/Liquidmetal . Wikipedia lists apple licensing this technology. Metal injecti

Yes, it was an amorphous metal alloy. I knew people from grad school that worked for the company. They have interesting properties: https://www.youtube.com/watch?v=_51frrQzCYM

I always enjoy seeing the HR-TEM of the quasicrystals after learning about them in grad school.

Yes, you need to know which features are evidence of mined vs. synthetic/lab grown. Although there is equipment now preloaded with software that can discriminate. I think its based on photoluminescence.

With close microscopic examination of inclusions and defects, yes you probably can. There are also spectroscopic differences. In general looking at finished jewelry, no, not really.

I had an M1 pro with the touchbar thing that I bought used for <$1000 after I had to give my work one back when I changed jobs. It was the best upgrade I ever made. I cracked the screen and bought a M4 air on black friday for $750 or som

My P1P at my work is having wifi issues. I'm considering just getting a Core 1, mostly because it has an ethernet port.

Neat, I was expecting more about how the semiconductor part is made. I toured the Lumileds/Phillips fab that closed in San Jose but you can't really see much.

Marking whiskers, as mentioned, seem like a good solution if you can keep them attached. They are designed to be easily visible on the ground.

Not sure, maybe people like the underdog or just like the business model, you pay for what you get. I flew them a couple times and it wasn't great.

I think the previous post was just referring to remote doctors purely interpreting imaging. Already at the dentist they are using AI to interpret imaging, my anecdotal experience is that over 50% of my dentists have missed an issue, the AI

I sent this to our electrochemist at work, maybe if we have some time we can test the coffee in the breakroom.

Americium is also chemically different and may not be as practical as cesium and rubidium to ionize and trap.

This was exactly my issue. There was no perception issue I could clearly identify the intermediate color as neither truly blue or green.

Yes, the logical rule would be 1 bag in the overhead per person. If they enforced carry-on sizes strictly and charged less for checked luggage the problem would probably go away.

I strongly recommend the Dawson City airport because they don't have security. The whole experience is much more pleasant.

by s0rce 5mo ago
I think its more likely that the people do know they just don't care and it helps them to put their backpack overhead so they do it anyways. There is minimal/no enforcement.

In college I had to handwrite all my exams and the pure math courses didn't allow calculators. For the latter you could realize you were doing it wrong if the answer was too complicated to write down. As others said the final was somet

From the article: “Voyager 1 still has two remaining operating science instruments — one that listens to plasma waves and one that measures magnetic fields. They are still working great, sending back data from a region of space no other hum
