Helium

And that's why helium's called helium.

And unfortunately, the helium atoms in liquid helium are right on top of each other.

This is a high altitude helium balloon.

And now simple atoms appear of hydrogen and helium.

It's that shape because the helium has to expand.

The helium atoms had to be very far apart.

The first one was that when helium atoms touch each other, they repel.

We need helium, and the helium is what we really need to go deep.

Feynman decided, as a sort of amateur helium physicist, that he would try to figure it out.

After about a few minutes, there was hydrogen and helium in the universe. That's all.

The universe was about 75 percent hydrogen, 25 percent helium. It still is today.

For a moment they become helium 5, because they've got five particles inside them.

Helium 3 very rare on the surface of the Earth, very common in space.

And that's what we use to inject, as we start to do our deep dives.

Helium splits out, and a neutron comes out and lots of energy comes out.

In the 1950s, people were trying to figure out how superfluid helium worked.

It consisted of huge clouds of hydrogen and helium atoms, and they have no structure.

The only way it worked is when the helium atoms were very, very far apart.

In the middle of stars, you're joining hydrogen together to make helium and then helium together to make carbon, to make oxygen, all the things that you're made of are made in the middle of stars.

(f) Data processing and interpretation of the ULYSSES GAS experiment on the distribution of interstellar helium.

So, that's that process there. Deuterium and tritium goes together makes helium 5.

4.2.3.6.3 Shells intended for the transport of helium can be filled up to but not above the inlet of the pressure relief device.

After about 400 million years, the first stars formed, and that hydrogen, that helium, then began to cook into the heavier elements.

The implication of that is that the wave function has to go to zero, it has to vanish when the helium atoms touch each other.

20. The Ariane high pressure helium tanks are designed to be emptied within a few hours via a calibrated orifice.

And the element helium was discovered just by staring at the light from the Sun because some of those black lines were found that corresponded to no known element.

I've always wondered whether the professionals, the real professional helium physicists, were just a little bit embarrassed by this.

So where you get slightly denser areas, gravity starts compacting clouds of hydrogen and helium atoms.

Now helium's a gas, there're a lot of reasons why helium's good, it's a tiny molecule, it's inert, it doesn't give you narcosis.

The thing was that that simple thing that he wrote down explained everything that was known at the time about liquid helium and then some.

Analysis indicated that with residual propellants, the nitrogen tetroxide and helium could be heated to temperatures that would generate pressure exceeding the strength of the material.

C. Space debris reduction practices NASDA has implemented the draining of residual propellants (LOX, LH2, N2H4) and residual helium gas of the H I H II second stage.

Storage and supply facilities (for liquid hydrogen, liquid oxygen, helium and nitrogen) and facilities to supply water and electricity are designed for common use by the Complex and adjacent installations.

After injection, up to 4 tonnes of the oxidizer and its vapours, up to 2 tonnes of the fuel and up to 60 kg of gaseous helium can still remain in tanks.

And that data, layer by layer, gets passed through the machine, starting at the base of the product and depositing material, layer upon layer, infusing the new layer of materials to the old layer in an additive process.

Now there are three levels of self to consider the proto, the core and the autobiographical.

Added protection.

They found in this gap, in between, a very thin clay layer, and that clay layer this very thin red layer here is filled with iridium.

We, all of us, are what happens when a primordial mixture of hydrogen and helium evolves for so long that it begins to ask where it came from.

And you make if from lithium. That reaction at the bottom, that's lithium 6, plus a neutron, will give you more helium, plus tritium.

21. NASDA has implemented the draining of residual propellants (LOX, LH2, N2H4) and residual helium gas of the second stage of the H I and H II launcher.

There are six layers three layers of plastic, aluminum which are are sealed together.

The project is aimed at atmospheric, ionospheric and magnetospheric studies.

In subparagraph (b), the expression each associated with specific geological formations is inserted to indicate that an aquifer system could consist of aquifers not only of the same geological formations but also of different geological formations.
