themedicalstate: The public health debate on masks is settled, said Joseph G. Allen, director of the Healthy Buildings program at Harvard. When you wear a mask, “You protect yourself, you protect others, you prevent yourself from touching your face,” he said. And you signal that wearing a mask is the right thing to do. With coronavirus cases still rising, wearing a mask is more important than ever. In this animation, you will see just how effective a swath of fabric can be at fighting the pandemic. Let’s take a closer look at how filtration works at the microscopic level. Magnified view of th ..read more

themedicalstate: Face masks have become an emblem in the fight against the coronavirus, with officials in the United States and elsewhere recommending — and in some cases requiring — that people wear them to help slow the spread of the deadly outbreak. Figuring out what to wear is not so easy.

fuckyeahfluiddynamics: In nature, color comes from many sources: like the pigmentation of skin and hair, the structural iridescence of a butterfly’s wings, or the refraction of a rainbow from water droplets. Recently, scientists discovered another source of brilliant color in simple, hemispherical water droplets.  When small droplets form on a transparent surface, they form concave shapes capable of total internal reflection. This means that two light rays entering from the same angle can follow different paths inside the droplet. After reflecting several times, the light rays exit the ..read more

cenchempics: Mirror ball In solution, this dye was green, but when Tridib Sarma evaporated off the solvent, the compound coated his round-bottom flask and revealed a copperlike luster, giving us a view of him and his laboratory. This polypyrrole dye has a highly conjugated network of overlapping π orbitals, which allows the molecules to strongly interact with light, giving rise to this strong color. Sarma, a postdoc at Shanghai University, analyzes the interactions between light and compounds like this one for potential use in organic electronics, artificial photosynthesis, and photodynamic ..read more

It’s a shiny disc, how do they get data on that, let alone that much?? Magic Like a vinyl disc, where a physical groove is marked into the vinyl, a laser marks the ink of a CD in a similar manner. A laser (your disc drive) can then look at the pattern in the ink and understand it. There’s no grooves on a CD tho??? They’re just really tiny, hence the laser. The smaller gr ..read more
