I suspect eutectic liquid InGa alloys would work, they stop wetting the glass when you are under vacuum. Although mercury is safe in the tube, just don't break the glass.

Robot characters keep you away from uncanny valley of creepy slightly off AI humans. Still fun though.

You could actually move very large quantities of water around and probably have a measurable impact. Like draining the California central valley aquifer.

At my previous job we made >1m wide 8um thick copper foil by electroplating it onto a giant titanium drum from blue copper sulfate solution. It was quite impressive.

But there are 100+ items for other people on the route on each delivery truck each day. So maybe better than individuals driving to the store. If you don't drive to the store that will for sure be better but thats abnormal in america.

There is a legitimate concern with space junk hitting useful stuff or even manned spacecraft but I think space is big and the sky won't appear bright soon. Not all satellites are that reflective and they need to reflect the sun, they don't just glow visibly.

Mine were like this is 2005. The math classes also didn't allow calculators, engineering classes did, but not graphing ones that could store information.

I used Freesco another single floppy distribution around that time. I tihnk I had in on old pentium 66 MHz

There are things like this: https://www.adafruit.com/product/5501 haven't used it, trying to find one for my mini pc, mostly so I can use a usb c power bank as a tiny DC ups.

If you are in the US then you can go to a hot place in the south west, even Eastern WA/OR or the California central valley when its >105F outside the wind blows and it feels like a hair drier or opening the oven, its not a cool breeze.

For antifoaming?

That's not always siloxanes, just atmospheric hydrocarbons.

Yes, you would also audit the quality system for your suppliers to confirm they are sufficiently controlling for upstream changes. In theory you can have all your ducks in a row.

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 off as not an important change.

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.

Scrolling this page is terribly awkward.

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.

glass is the general materials science term for an amorphous non-crystalline solid

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 injection molding is also a thing but I haven't heard it called liquid metal. Usually its MIM.

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 something which I'm using now.

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