Emission Spectra Of The Elements

Someone said this looks like blood and now I have “bad blood” stuck In my head please don’t judge me

At sub zero temperatures, moisture from the surrounding atmosphere condenses almost immediately. The dendritic (tree-like) form of the crystallization is a natural fractal pattern.

As a rule, except in conditions where supercooled droplets are present in the air, frost will form only if the deposition surface is colder than the surrounding air. For instance frost may be observed around cracks in cold wooden sidewalks when humid air escapes from the warmer ground beneath. Other objects on which frost commonly forms are those with low specific heat or high thermal emissivity, such as blackened metals; hence the accumulation of frost on the heads of rusty nails.

Wind tunnel testing plays a major role in the planning of many space missions. Here a model of the Mars Sample Return Orbiter is tested at Mach 10 to determine the heat shield’s response to aerobraking off Mars’ atmosphere. The colors are the result of electron beam fluorescence, in which an electron gun is used to ionize molecules in the flow, which causes them to emit photons (light). The technique can be used for flow visualization–as in the case of the shock waves shown here–or to measure flow characteristics like density, temperature, and velocity.

The use of 3-D printers has opened up the possibility of on-demand implants, prosthetics, and medical devices. This week, scientists reported that they were able to 3-D-print the first stable ear, bone, and muscle structures out of living cells and implant them in mice. The results were published in Nature Biotechnology. Anthony Atala, the director of the Wake Forest Institute for Regenerative Medicine and an author on that paper, describes the challenges of 3-D printing living cells and how the technology could be used in bioengineering body parts.

As a chemist, this entire conversation is triggering my lab safety nerves. Have you geologists heard of PPE?

we do need to lick the rocks to identify them though. i appreciate your concern but...we actually do need to lick the rocks.

Sounds fake but okay
