That's enough to stick six 42-inch
plasma
TV's to your wall, no nails.
There are many basic properties about this
plasma
that still confuse us, still puzzle us, and still push our understanding of the physics of the very hot.
Horned lizards readily consume harvester ants, resisting their envenomed sting with specialized blood
plasma.
It's a big ring of magnetic coil, superconducting coil, and it makes a magnetic field in a ring like this, and the hot gas in the middle, which is called a plasma, is trapped.
So this is the inside of one of those donuts, and on the right side you can see the fusion
plasma
in there.
When you make fusion, the energy comes out as neutrons, fast neutrons comes out of the
plasma.
And then you have some pistons driven by pressure that goes on the outside, and this compresses the liquid metal around the plasma, and it compresses it, it gets hotter, like a laser, and then it makes fusion.
So when you compress that, the
plasma
cools down faster than the compression speed, so you're trying to compress it, but the
plasma
cooled down and cooled down and cooled down and then it did absolutely nothing.
So we accelerate the pistons with steam, that takes a little bit of time, but then, bang! you hit the piston, and, baff!, all the energy is done instantly, down instantly to the liquid, and that compresses the
plasma
much faster.
So it's going to be a big machine, about three meters in diameter, liquid lead spinning around, big vortex in the center, put the
plasma
on the top and on the bottom, piston hits on the side, bang!, it compresses it, and it will make some energy, and the neutron will come out in the liquid metal, going to go in a steam engine and make the turbine, and some of the steam will go back to fire the piston.
Okay, we also built this injector, so this injector makes the
plasma
to start with.
It makes the
plasma
at about a lukewarm temperature of three million degrees C. Unfortunately, it doesn't last quite long enough, so we need to extend the life of the
plasma
a little bit, but last month it got a lot better, so I think we have the
plasma
compressing now.
However,
plasma
is difficult to compress.
This would result in a flood of x-rays that would spread out in a bubble along with exotic particles,
plasma
inside, centered on the pitcher's mound, and that would move away from the pitcher's mound slightly faster than the ball.
Now, after 70 nanoseconds, the ball will reach home plate, or at least the cloud of expanding
plasma
that used to be the ball, and it will engulf the bat and the batter and the plate and the catcher and the umpire and start disintegrating them all as it also starts to carry them backward through the backstop, which also starts to disintegrate.
As an example, we could have taken the blood of survivors, processed it, and put that
plasma
back in people to protect them.
Instead, we've reasoned, then, that it must be the soluble factors, so we could collect simply the soluble fraction of blood which is called plasma, and inject either young
plasma
or old
plasma
into these mice, and we could reproduce these rejuvenating effects, but what we could also do now is we could do memory tests with mice.
What I'm showing you now are unpublished studies, where we used human plasma, young human plasma, and as a control, saline, and injected it into old mice, and asked, can we again rejuvenate these old mice?
In stark contrast, this mouse here is a sibling of the same age, but it was treated with young human
plasma
for three weeks, with small injections every three days.
And it also suggests that there is something not only in young mouse plasma, but in young human
plasma
that has the capacity to help this old brain.
We're running a small clinical study at Stanford, where we treat Alzheimer's patients with mild disease with a pint of
plasma
from young volunteers, 20-year-olds, and do this once a week for four weeks, and then we look at their brains with imaging.
One of my favorite examples of liminal excellence comes from the late Dr. Claudia Alexander, a black woman
plasma
physicist, who passed away this past July after a 10-year bout with breast cancer.
These leukocytes can be so large that they nearly fill a capillary causing a
plasma
space to open up in front of them.
In the perfect world of plasma, there are no collisions and no friction to provide the stability like we are used to.
But still, if you slightly perturb a
plasma
equilibrium, you will find that the resulting electric field spontaneously vanishes, or damps out, as if by some mysterious friction force.
This paradoxical effect, called the Landau damping, is one of the most important in
plasma
physics, and it was discovered through mathematical ideas.
One misconception is that fire is a plasma, the fourth state of matter in which atoms are stripped of their electrons.
By contrast, fuels like wood and paper burn at a few hundred degrees —far below the threshold of what's usually considered a
plasma.
So if fire isn’t a solid, liquid, gas, or a plasma, what does that leave?
Well, it turns out that if we were to zoom in at radio wavelengths, we'd expect to see a ring of light caused by the gravitational lensing of hot
plasma
zipping around the black hole.
