If the trauma or adversity involved another person who was untrustworthy that we trusted, it calls into question our ability to evaluate people and decide who So Magneto came through the other side of the Holocaust and had a very different philosophy than Professor X.
By the 1970s, we got superconducting quantum interference devices, or SQUIDs. These magnetometers were incredibly sensitive, detecting fields as weak as a few femto Tesla. To no surprise, the US military quickly strapped these SQUIDs to planes and helicopters, and they tried to use them to detect large magnetic signatures
They can't handle large dynamic range of background fields and electromagnetic interference. - Future magnetometers offered solutions, but they also had their own drawbacks. There were always issues with either shielding or sensitivity or dynamic range that made them impractical for detecting heartbeats out in the field.
In space, the influence of Earth's magnetic field extends tens of thousands of kilometers around the planet, creating a bubble known as Earth’s magnetosphere. The magnetosphere is constantly moving and changing as it repels and traps charged particles from the sun and the rest of space, protecting Earth from radiation.
In this image here, you see somebody not so much with an inverted toilet on her head, but this is an imaging device, a magnetoencephalogram. And magnetoencephalography is a very powerful technique that allows you to actually see your brain changing or activating in real time if you wanted to. So all these things are really exciting, and it sort gives us an opportunity to see how suggestion affects us in real time,
Because we know where the spacecraft is now. The magnetometer is working as expected.
So my day job is studying things like how stars form and how planets evaporate. I do magneto fluid-- large-scale supercomputer magneto fluid dynamical simulations of astrophysical gas dynamics. But because I do a lot of work with the public, I've ended up having to think a lot about climate change,
Until the 1990s when physicists started looking into diamonds that might eventually be able to sense magnetic fields while potentially getting around the drawbacks. - These new quantum magnetometers work at room temperature operation, and that's what's really exciting about them. They're also a solid state sensor, which, you know, can be very practical for some applications and can be made into like a more robust kind of sensor.
This is how an NV diamond magnetometer works. Was the diamond magnetometer ever used to detect a heartbeat? - So what has been done for sure is, you know, for certain is detection of magnetic fields generated by neurons.
- With the rise of GPS spoofing and jamming over the last couple of years, that could be incredibly powerful. So NV magnetometers do exist with these synthetic diamonds, and they do have potential military applications. It's just that detecting heartbeats kilometers away probably isn't one of them.
that what Joe Biden did is he was pissed What does magnetoreception feel like to a bird?
I think the show is an opportunity to speak to scientists about what they don't know. What does magnetoreception feel like to a bird? We're going to get the answer through fossil poop.
the world works. So here I am showing some of our teachers in Nevada that we work with, and there we have buried a magnetometer, which is an instrument to study Earth's magnetic fields. And the teachers actually use this with their students to understand how the Earth's magnetism is changing.
You could also do resistivity, you could do ground penetrating radar, which all measure different things in the subsoil. What the magnetometer survey's doing is measuring the magnetic field. It's basically giving you anomalies, positive and negative anomalies, based on the magnetic field below.
Nothing about the context, the stratigraphic unit, I should say, of this artifact. looked interesting on the magnetometer survey.
variety of means, physical means, those particles. You push them together. The most common is called laser inertial fusion. We call the technique that Helion uses magneto inertial fusion, because it does a little bit of both.
Now, we've simplified it a bit, but by measuring how spaced apart these lines are, you get the field strength. This is how an NV diamond magnetometer works. Was the diamond magnetometer ever used to detect a heartbeat?
The sun is constantly pushing energy into space in a flow of electrically charged plasma called solar wind. That solar wind helps shape our magnetosphere, compressing it on the sun-facing side, and stretching it out in a tail behind the shaded side, so that it wraps around the Earth. Without that magnetic field the earth wouldn’t exist at all.
And I said, well, The Container Store. And then I was going through the magnetometer. And the TSA guard looks at me.
So mine, I brought a drone. And here we're protected by our magnetosphere, but on Mars you'd need to shield yourself somehow.
Because we know where the spacecraft is now. And we've already gotten some good magnetometers readings.
until the phone went dead. Are there other scientific instruments with magnetometers doing any sort of magnetic science?
If Earth’s core didn’t produce a magnetic field, we’d be in the same boat. So, Earth’s magnetosphere is pretty essential. But no matter how tough our planet’s bodyguard is, it’s not indestructible.
And there's some really remarkable technology. So we've got Rory's really high-resolution magnetometers, accelerometers, and things like that that he's trying to put on birds. And then we've also got tags that-- this is probably the largest tag that we feature in the book.
We do geophysical survey of some sort. What we have done on the site is called the magnetometer survey. You could also do resistivity, you could do ground penetrating radar, which all measure different things in the subsoil.
Nothing about the context, the stratigraphic unit, I should say, of this artifact. Now one of the other problems with the magnetometer survey, and again, how I'm saying that we really have to bring together different techniques.
So I wanna thank Ground News for sponsoring this part of the video, and now let's go figure out how those diamonds actually detect magnetic fields. Well, for something to function as a magnetometer, it needs to respond to a magnetic field in a way that we can detect. Now, a pure diamond is just an ordered lattice of carbon atoms, so it doesn't react to magnetic fields in a meaningful way.
This is a computer generated model representing the heart field that has been measured with magnetometers.
Nothing about the context, the stratigraphic unit, I should say, of this artifact. I ask you to look at that area right there on the magnetometer survey.
Nothing about the context, the stratigraphic unit, I should say, of this artifact. One, I'm always going back to the magnetometer survey and I'm saying, OK, that really did not-- that whole thing is there, but there's no indication what any of that is.
square, which has got a little magnetometer and a little gyroscope and a little radio and a solar cell and a microcontroller.
First, normally this signal is so weak that it can only be measured in a hospital setting with sensors pressed nearly against the chest, the source said. But advances in a field known as quantum magnetometry, specifically sensors built around microscopic defects in synthetic diamonds, have apparently made it possible to detect these signals at dramatically greater distances.
Even the slightest vibration of the detector would corrupt the measurement, not something that could work on a helicopter or a military drone. But, pretty soon, magnetometers got better. By the 1970s, we got superconducting quantum interference devices, or SQUIDs.
Now, these secret energy platforms of NV centers were mapped out by the '90s. But for a long time, no one thought to use them as magnetometers. - There was a decade before the light bulb went on for a bunch of us to think about them as sensors.
They thought the world was ending, and you can’t really blame ‘em. But what actually happened was a geomagnetic storm: the solar storm’s particles had disturbed Earth’s magnetosphere, and that disturbance interfered with technological and electrical systems across the world.
They're all aligned with the magnetic field, so it's called magnetoreception.
We called it-- if it kind of got off-course and went through the geo belt-- our space blender. So we're looking at that, and it's got magnetometers for measuring the Sun's magnetic field, in it has cosmic ray detectors.
What this spacecraft did-- it was one of three spacecraft. Two were in Earth's orbit, circling here between low Earth orbit and the Earth's magnetosphere to measure all of these parameters, from cosmic rays, gamma rays, magnetic fields-- everything about the Earth.
Many of the powers in the show are similar to X-Men. Claire's healing powers are like Wolverine's healing deal. There's like a guy who, you know, controls metal like Magneto
something goes wrong, the reactor simply stops. And there's no carbon emissions. On a more technical side, Helion uses a different approach to fusion than has traditionally been done. Most fusion efforts have used tokamaks, which are these giant donut-shaped magnetic containment chambers. Helion uses pulsed magnetoinertial fusion. David gets into the super technical physics and engineering details in this episode, which was fun and fascinating. I think it's important to

variety of means, physical means, those particles. You push them together. The most common is called laser inertial fusion. is that it oscillates around that field line. And so the way I think about this is if you think about the Earth's magnetosphere again, and you think
Like in any other magnet, the magnetic field moves in a continuous loop, entering Earth at the north magnetic pole, and leaving from the south magnetic pole. In space, the influence of Earth's magnetic field extends tens of thousands of kilometers around the planet, creating a bubble known as Earth’s magnetosphere. The magnetosphere is constantly moving and changing as it repels and traps charged particles from the sun and the rest of space,
We can actually use techniques, very advanced technological ways to look at the functioning brain, the live, functioning brain. In this image here, you see somebody not so much with an inverted toilet on her head, but this is an imaging device, a magnetoencephalogram. And magnetoencephalography is a very powerful technique that allows you to actually see your brain changing or activating in real time if you wanted to.
It provides all our oxygen. It even protects us from the radiation, with the magnetosphere around it.
Here we have a couple of minutes of data from a circling vulture that they've attached a tag to. So you can see, there's all kinds of different senses that they've crammed into this small device now-- accelerometers, magnetometers, GPS. And so this is like a feed of information they have about the birds' spiraling behavior, looking at turbulence over the wings and that kind of thing.
And those are usually stone buildings, things like this. And by the way, I should point out that this isn't something-- we don't pull out our own magnetometer survey. This is one of those collaborations.
Because we know where the spacecraft is now. Yeah. We already have gotten our first science from the spacecraft, from the magnetometers.
This year, we couldn't get that done. They didn't have the equipment for it. But you also have to go through security checks, just like an airport. So we have about 130 Magnetometers
