@crowleylab @skdh A scanning drone at 100m altitude might pick it up at 0.1fT level, starting from 100pT according to AI

NV-centers hypersensitive to magnetic field, tune with a low-pass filter and then a band-pass peaked at 2 hz (120bpm). Set them up in a phased array to cancel backgrounds. they literally detect the ion fluxes of potassium, sodium, and calcium as it pumps through the heart. Dipole approx is good enough. There’s no way they got a hit at 40 miles.

Yes, you can use quantum physics to measure magnetic fields very precisely, but no, you cannot do this over miles of distance, that's insane. That said, infrared radiation is also electromagnetic of course and everything is quantum anyway. Yours sincerely, Quantum Sabine.

@bubbleboi It's similar tech as dragging a detector behind an aircraft for prospecting and finding ores

@bubbleboi Heart magnetic field is ~100pT, SQUID magnetometers have sensitivities of around a fT, maybe ~0.1fT given enough averaging time. Dipole magnetic fields decrease as 1/r^3. After some math it seems conceivable that an aircraft could pick it up from 100m or so in the air

This is not bullshit. I worked on this exact use case in college & then at an internship at the army research lab. The field is broadly known as remote sensing. It’s already been well known for some time that you can use radar & even WiFi signals to pick up your heartbeat, breathing, gait, & even emotions with high confidence but using other optical techniques you can also even tell the chemical makeup of a material from far away using a focused laser beam. My guess is this system was probably using continuous wave radar (24-60 GHz) mixed with Laser Doppler Vibrometry (LDV). LDV works well for this because the technique relies on measuring the phase difference between two beams of light for ultra high precision measurement. One beam acts as your reference and stays inside the instrument & the other beam goes out, hits the target, and bounces back. When the two beams recombine on a photodetector, they interfere constructively or destructively depending on the phase difference between them. If the target surface is perfectly still (flat land) the phase difference is constant. But if the surface is moving even by nanometers the reflected beam picks up a tiny frequency shift due to the Doppler effect. The reason you can pick up nanometers level of changes (even picometers) is because phase detection can resolve at a fraction of a wavelength which it self is in nanometers. This was already proven out at up to 200 meters publicly and to go even farther distances it was hypothetically possible but was an engineering challenge that im not going to get into how you would solve.

The CIA used a secret new tool, “Ghost Murmur,” to locate a downed U.S. airman in Iran, its first real-world use. It can detect a human heartbeat from miles away using AI and advanced sensors: “If your heart is beating, we will find you.” Source: NY Post

By 30 you need to have lived an adventurous life. Gone to mysterious countries by yourself. Started and failed businesses. Many romances. Made mortal enemies. Roundtrip 7figs. Climbed mountains. Escaped death multiple times. Crashed cars. Lost it all n made it back. Adventure

Why do I focus on women's shortcomings and not give equal time to men's? Because women are harder to understand. A LOT harder. Even if you are one. Also, because I am not a woman who dates men, so I don't know what that's like. I don't speak if I'm not sure of what I'm saying. The Western (and Westernized) world is facing a crisis of immaturity. That's why I talk so much about developmental psychology (pic related). It helps me explain modern behavioral changes in terms of degraded development. An immature man is simple and easy to understand. He doesn't take responsibility. He takes, but doesn't give. He doesn't put in his best effort. He doesn't have a mission. He isn't self-directed. He is still mentally a child. He hopes or even expects that someone or something other than himself will make his life work. They call it "Peter Pan syndrome," as if it's a disease. It is actually just the failure to fill the role of a man, and staying a boy at heart. This may be due to personal weakness, disenfranchisement, or both. Simple. An immature woman is much more complex (and usually more dangerous). When a girl becomes a woman, she is not expected to "woman up" and provide for others and keep her complaints to herself like men. She is expected to understand, nurture, and care for children, as well as whoever or whatever it is that provides for her, typically a husband. In the same sense that an immature man never takes on the responsibility to go get value from the world and put it to good use, an immature woman never takes on the responsibility to nurture anything but her own enjoyment. Just like men, they remain self-oriented, like children. This is what leads to the modern love of abortion ("I don't have a responsibility to nurture the next generation"), but what's even more key to understanding this situation is that they also do not take on the responsibility to nurture the men who provide for them ("I don't owe you anything"). They feel perfectly fine accepting provision from men who get nothing back, whether directly or through an institution. Without that responsibility internalized as a value structure (level 4 on this chart), women tend to withhold their capacity to nurture from men who offer to provide for them. A mature woman sees an offer of provision from a suitable mate as an honor that must be reciprocated. An immature woman sees the same offer as weakness. (Ew, he thinks I owe him something because he provided XYZ? I'm not settling for anything less than REAL LOVE (temporary sexual excitement)). This detachment of provision from relational responsibility causes women to seek to meet their needs independently of the needs of others, or of society in general (level 3 on this chart). Because that would be "oppression." Now, once you understand that provision has been separated from relationship in a large and growing segment of the population, and that these women feel perfectly justified in accepting provision from simps while seeking excitement from bad boys, you can see why the immature woman demands so much more attention than the immature man. Immature men just need to put in more work and do the best they can (when society allows it, which it doesn't right now). Immature women, on the other hand, hurt the men that love them and love the men that hurt them. Most of them don't know it, because women are hard to understand (even to women), but they are rewarding the behavior that rots society and punishing the behavior that builds it. They chase the men who use them and use the men who chase them, and men are adapting by becoming even bigger pieces of shit in order to compete. What's the solution? I dunno. No solution, only problem. It's going to require a bottom-up and top-down reconstruction of more or less all of our institutions, cultural values, and social norms. Can we do it in time to save anything? I dunno, lol. Ok thanks for letting me ruin your day bye
