The elephant's foot is actually safe to visit now! It's pretty cool, if you are a scientist with a good reason or if you pay enough the will take you down to see it. It is still radioactive so you can't go hug it or something but you can be in the same room for a few minutes without much concern.

Impurities burnt off the vessel probably, maybe helium ash? Also, you're only seeing radiation around the edges of the plasma because it's "cold" enough to emit light in the visible range. The core, which is around the edges of the field of view here, is so hot that it's emitting X-rays.

Helium will float up into his sinuses, the other stuff will stay in his lungs, slowly asphyxiating him. How long does he have after that stunt to pour it out of his lungs?

>>1760291
I would imagine it depends on how much he really inhaled, and how much denser it is compared to air, as in, can air push it out of his lungs as he breathes?
It probably can, because he's alive, so I think it's only dangerous if you do fuck all, hence "don't try this at home", he probably had to do some heavy breathing type shit to clear it, maybe even be upside down for all I know.
You should try asking him, I think he has social media presence.

This is really incredible, I really want to see the source of this. It so perfectly incapacitates that human existence is not merely the pursuit of comfort and pleasure as so many people have cynically come to believe. Gong to space makes him unhappy, and yet he keeps going. I'm sure he has other career options asides from being a cosmonaut so he is not desperate for money, and it doesn't seem like he's too motivated by ideology either. He's going because at the very core of human essence, even beneath the simple hedonism, is the far more noble urge to explore and advance both ourselves and our communities. To go where no man has gone before so to speak.

File: Sulfur Fire, Video 1, Horizontal.webm (3MB, 640x360px) Image search: [Google]

3MB, 640x360px

Sulfur Fire - Washakie County, Worland, WY07/07/2017 WFD was called to Smet Recycling on HWY 20 North for a report of an unknown type of fire. Upon arrival we found that the fire was a sulfur mound that had been ignited. Despite the beautiful flames, burning sulfur creates a hazardous gas called sulfur dioxide. WFD was able to position apparatus in a safe location and lay in a line to extinguish the fire. We captured the video, while in full PPE and wearing SCBA's during a size up of the situation, as crews were setting up for suppression.
** Update / Response to comments and questions: Burning sulfur creates sulfur dioxide (SO2) gas that has a very strong, choking odor. The fire was burning in a “bowl” shaped area, allowing all runoff to be collected in the fire area. A minimal amount of water was used to cool the surface of the sulfur and reduce the temperature below the molten stage. Adding water to an SO2 gas creates sulfurous acid, (not to be confused with sulfuric acid) which can be related to “acid rain”. Apparatus and personnel placement as well as careful monitoring of the weather conditions in relation to smoke and chemical plume is very important. The deposits in rural Washakie County are leftover from the Texas Gulf Sulfur Plant that operated north of Worland in the 1950’s. Much of the sulfur is mixed heavily with soil and is not 100% sulfur concentrate. This is a type of fire that is not common but needs to be addressed and dealt with safely and quickly. Fortunately the WFD has Hazmat Technicians and we have an understanding of this as we deal with H2S and SO2 on a somewhat regular basis.

I don't see this working out. I donated sperm for years back when I was at uni and they were very strict about lube. They have you some surgical grade lube if you asked, but they said if it got into the donation cup they wouldn't be able to take the sample.

remember that water can absorb more energy than air as it can also transmit more energy than air in the short distance, water is heavier than air, so it gives a higher impact in short distance but it cant transmit lots of energy to long distances, am I right?

>>1759965
what field of math would this be?

>>1763792
Are you comparing them to average everyday people? Because they arent average everyday people. They have to have exceptional technical skills and simultaneously be very sociable, cooperative and constructive (imagine being stuck in a cramped spacecraft for an extended period of time with anyone different)

>>1782180
What do you mean by most efficient burn time?

>>1758076
>>1760807
To avoid killing stuff and destroying too much shit nearby, the area surrounding the SRB's and thrusters gets showered with ridiculous amounts of water to absorb as much of the noise/shock as possible, and maybe avoid killing everything within whatever radius the killzone is.
That little bugger is too close to the rocket, me thinks. Probably didn't last long. Unless he has a relatively deep hole to hide in, I guess.

>>1763920

That's some kind of topology and transformations stuff, so you'd probably want to know multivariable calculus, algebra, matrices, derivatives, geometry, etc.

Fun stuff: Non-euclidean geometry allows triangles to have their angles add to over 180 degrees

>>1759972
this honestly needs to be a webm so I can pause it and follow along

>>1778221
My college math teacher actually went over the proofs for the quadratic equation, and so long as you can follow along, it helps understanding tremendously.

High school math teacher was all "don't wurry bout it". Stupid.

>>1759976
I wish you'd named these so I had an idea what specifics were being covered and could look them up later while studying as visual aids.

Because in exchange for losing 3 tons of payload to orbit, you get your fuselage and rocket engines back.

>>1790568
a full rocket is heavier than a nearly empty one.
same force but more extra velocity

>>1762552
to be fair, that was because we were able to develop fission reactors shortly after we made fission bombs, so they assumed that because we made fusion bombs, that fusion reactors would be made soon after
as it turns out, it's a lot fucking harder to do fusion efficiently, and resulted in people giving up on it until recently

>>1782180
Engines are expensive to build.

Simple as that; but complex if we go deeper into as why.

>>1762641
I fucking love electromechanical things; Especially when they sound as cool as this thing and have the sweet old noise of a typewriter on crack.

>>1793512
well; funding for fusion development went to shit in what scientists call the "fusion never" funding plan.

All the development plans for fusion projected completition somewhere not after the 2000s; but none of them were followed.

Complex variables foremost.

What we are seeing are mappings. Basically f(z) = u(x,y) + iv(x,y)

To be fair, this an absurdly overcomplex way of solving a quad. On paper, with numbers you would just factor it. Really once you learn logs and quads, this stuff isn't really that hard.

Don't worry pretty soon you will be able to become immortal. Then your body will regenerate back to how your body was with 25-30 years old and stay that way until you die a non natural death.
