Overall, I agree, when I ask things I'm an expert in and do professionally every day. I get very good useful answers. When, for example, our marketing people, ask about the science…

As long as there is money people will come just for that. That's where we got tech bros, like finance bros, instead of just a bunch of nerds making cool stuff.

Durable goods also seem much less durable. I go through way more fridges, dishwashers, etc then previously.

I just bought a 1 year old iPhone 16 on Facebook marketplace for $400. You can find pretty good prices if you don't need the latest device.

yes, DMF has a much higher boiling point. Its much more polar.

I've always heard of using nitromethane to remove super glue...

I wonder why Chloroethane / ethyl chloride was chosen. I don't think I've ever seen this for anything, other than a synthesis precursor to useful stuff.

Yes, the AI models are so useful in areas where you are an expert and can guide it in a useful way. I use multiple chats delay to help figure out client projects.

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 …

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 t…

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…

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 …

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.
