Secretagentpeptidebond - Mostly Harmless.

Four evenings a year, the setting sun aligns perfectly with Manhattan’s street grid, creating a breathtaking wash of illumination along the cross streets, and tonight is one of them! In this video, Frederick P. Rose Hayden Planetarium Director Neil deGrasse Tyson, who first noted the phenomenon more than a decade ago and coined the term “Manhattanhenge,” explains the phenomenon.

Spidery crystals appeared after rotovap-ing. I think they look like dandelion fluffs.

Introducing the most versatile piece of laboratory equipment: the septum. It’s a septum! It’s a makeshift SureSeal! It’s a makeshift vial adapter! It’s a holder for reaction tubes!

In this video lichtenburg figures are burned into wood using a microwave oven transformer. The results are spectacular. (Video) Facebook | Instagram | Scary Story Site

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.
