Brain-Rain.

Science in action. And also, goofing off.

Join me in my quest to become brilliant.

Yes, I am still alive despite the lack of original content.

I recently got back from DC so I have a ton of museum footage to go through. Also I’ve recently taken up terrarium building as a hobby, which is surprising to absolutely no one. After my summer job is over I’m planning on working on a lot of my own stuff soon… probably writing and drawing practice for a much bigger project. Don’t know if I’ll post anything about it though. If I did I’d probably do it on a separate blog. I’ll keep you guys updated if you are interested.

If not, then please enjoy the daily queue. But I’m still online. I’m always online. Lurking. Like a shadow.

Subliming 4-amino-4H-1,2,4-triazole. It is quite interesting that a molecule with that much nitrogen in it does not decompose at even 160 °C,  it only sublimes a bit. Sublimation is the transition of a substance directly from the solid to the gas phase without passing through an intermediate liquid phase.
The 4-amino-4H-1,2,4-triazole looks like this:

spaceplasma:

Microwave Induced Plasma

This coaxial microwave plasma source (MPS) generates plasma without using a magnetic field. It works like an inverse luminescent tube excited by microwaves. The coaxial microwave plasma generator consists of a copper rod (antenna) as inner conductor surrounded by quartz tube filled with argon gas, the plasma is the outer conductor. The inside of the tube is at atmospheric pressure whereas the outside is at low pressure. The plasma formed around the quartz tube acts as an outer conductor in such a way that a spatially extended surface wave is created, just in an equivalent (‘inverse’) situation to that found in the Surfatron source (where the plasma is inside the tube instead of outside).
The microwave with a frequency of 2.45 GHz generated by two magnetrons is fed into the copper rods at both ends. On the outside of the tube, in the low pressure, the microwave fields ignite the plasma. The plasma represents a conductive medium so by increasing microwave power the plasma grows from both ends along the tube, and a homogeneous plasma is formed. The high power microwave breakdown at atmospheric pressure leads to the formation of filamentary structures. These striations or string-like structures, also known as birkeland currents, are seen in many plasmas, like the plasma ball, the aurora,lightning,electric arcs, solar flares, and even supernova remnants.

Evening Post: August 12, 1899.
"She immediately alighted, caught hold of the astonished youth, and gave him a sound thrashing, using her fists in a scientific fashion…”

I would love to know what this means.

I think that might be code for “punched him in the balls with devastating accuracy”.
