It's not a SQUID. There is new technology (quantum magnetometry) that measures slight shifts in molecular energy levels inside defects in synthetic diamonds. One of the google/alphabet spinouts from their quantum computing research is commercializing the technology (SandboxAQ).
The have a non contact MCG, like a EKG, but no electrical contacts. They can definitely "see" the heart beating from a few feet away.
SandboxAQ is also developing a navigation version. Put this sensitive magnetometer on a plane. You get very sensitive measurements of the local magnetic field. Once they have a region mapped, you can get exact positioning just from measuring magnetic fields.
You can extrapolate from SandboxAQ and get long range detection of a human heart. I don't know if it's real, but if so it's probably came out of that research effort.
You are correct, it is not based on SQUID. But, I think SQUID is technically a class of quantum magnetometer? Quantum magnetometry is pretty vague, since most high-end magnetometers use some sort of quantum mechanics.
I think the term you're looking for is atomic-optical magnetometer. Someone posted a DARPA project (AMBIIENT), that uses one. What's special about the atomic-optical magnetometer, is that it measures the gradient directly. With SQUID, if you have two SQUIDs in a uniform magnetic field, you can't determine the vector of the field. But, with atomic-optical magnetometry you can.
For elementary school age kids, maybe even middle school, try getting them started with the app "Euclidea".
They won't think of it as math. It's gamified geometric constructions. Starts simple, "how do you bisect an angle" with a compass and a straight edge. It goes to a very high level that will challenge anyone.
Yeah, people underestimate how hard it is to get a movie into a theatre AND get people to pay for a ticket.
Hollywood can barely get any well made movies past $100 million these days unless it's based on some well known franchise (minecraft, Captain America, Snow White) or it has some well known actor.
Technically they want to limit indirect costs to 15%. This currently ranges from 50%-100%. Indirect costs have two components, facilities and administration.
Facilites are the cost of buildings, electricity, janitorial service, etc. Think of this as things that might be included in the rent if you were renting a place to do the research.
Administration costs are mostly salaries for people, administrative and clerical staff. Not the people directly doing the research (that's a direct cost), but the people in charge of safety/compliance/legal, etc.
Administrative costs have been capped at 25% for a few decades. Facilities costs are not capped.
I think part of the problem is that universities have lots of people who do one job and that job is not everyday. For instance, where I'm at we have two people in charge of summer enrollment. That seems to be it. They are way way overworked for about two weeks at beginning of the summer. I have no idea what they do the other 50 weeks of the year. I think their boss is happy as long as they deal with summer courses.
“I have no idea what these other people I don’t work with do, so it must be nothing” is a really naive and insulting thing to say. They probably don’t know what you do either, would it be fair to say you do nothing of value?
It was an early stock discussion forum. It grew rapidly when search engines started indexing everything and this forum had a URL for each message that was easily indexable.
Suppose the average post is about 1 paragraph long. One paragraph is about 150 words. So 192211 * 150 = about 29 million words. For comparison, the Lord of the Rings trilogy is only around half a million words.
It wouldn't surprise me if there are more words about Qualcomm in that thread than the total amount of internal and external documentation and financial guidance that Qualcomm itself has ever produced.
Surely users aren't expected to read the entire thread before adding a post? But I think I remember seeing old forums where that basically is the expectation. And honestly... that's pretty cool. It seems better than the new social media, where we keep having low-effort recurring debates. I like the idea of adding to an enormous pile of scholarship in cyberspace. A Ship of Theseus discussion which may outlive any individual participant, but has a semblance of continuity all the same, like an undergraduate college society with a 100+ year history.
Time for a cyberpunk revival. Retro-cyberpunk, we could call it.
