Generally by around junior year of undergrad as a physics major, you realize "holy shit, it's just progressively improving models all the way down - and none of these models get to a 'real' understanding of what's going on underneath the hood".

That's the reality. We don't know what quantum measurement or wave function collapse 'is', where the boundary between classical behavior and quantum behavior sits, why general relativity works well but we can't seem to get it to play nice with quantum mechanics - and the proposals to do so don't really yield a satisfying sense of understanding either.

Anyway, I find it very surprising that these would be revelations to any physicist. The thousandth time you write the "approximately equal to" operator as an undergrad or drop all the higher order terms from a diff-eq it is self-evident what level of understanding you can get from physics.

The pulse oximeter was developed in 1972 and were common by the late 80's. Patent 10,588,553 was just granted this year. What innovation did Apple "steal"?

I just heard a story about this. When they bust people for prostitution if the prostitute turns out out to be a minor, it is labeled sex trafficking, because a minor can't legally concent. Actual cases of sex trafficking are extremely rare in the US. This is why "A lot of time, they're minors". Pretty much all the time. They also tend to do press releases about multiple arrests without making it clear they are all independent cases. This leads people to falsely believe there are sex trafficking rings, like Qanon says. Sorry, I can't find a link. Some guy talking about his book on NPR.

Sure, that's the first definition:

But right under that it says,

These locations are buried under ~1 km of ice. They are pretty well protected.

Acer aquired Gateway in 2007.

Acer announced today that it has completed the merger of its indirect wholly owned subsidiary with Gateway

Yup.

Except when they did.

From my poor understanding, it seems like CMOS was the big win for Si. GaAs can't do it, because of poor hole mobility. It looks like non-Si semiconductors are going to be used for 5G amps, but the rest of the chain will still be all Si.

You can't get infected with COVID-19, but the Sputnik, Cansino and Astra Zeneca are using a vector based vaccine where they are modifying the common cold virus to include SARS COV2 spike protein DNA. Three candidates rely on weakened human adenoviruses to deliver the recipe for the spike protein of the pandemic coronavirus, while two use primate adenoviruses and one uses measles virus.

So, technically you are getting a mild infection. The small pox vaccine also gives you a mild infection.

Idiots and assholes it seems.

There have been lots of insignificant mutations, The new report, however, did not find that these mutations have made the virus deadlier or changed clinical outcomes. All viruses accumulate genetic mutations, and most are insignificant, scientists say.

My wife got dive bombed and sassed by a hummingbird, because I hadn't filled the feeder recently.

Yes, when monkeys failed to turn into us, apes evolved and created a technological civilization!

I've seen pigeons used to fly up in my pecan tree knock the nuts down onto the road, then come back later to eat the cracked nuts. I'm not impressed by a crow doing it.

We barely have ability to simulate a protein folding. We are no where near simulating a single subcellular structure. What makes you think we can simulate an entire brain?
