Needle playing a record | Victrola Coffee Roasters
Coloured scanning electron micrograph (SEM) of the needle (stylus) of a record player in a groove on a record. A record is used to store sound. It is produced by a machine with a head which vibrates in time to the sound being recorded. This cuts a groove in the record which varies according to the vibrations. A needle can then reproduce these vibrations as it runs along the groove and these, when amplified, produce the original sound.
Oh my god this is exactly what I wanted to do in the lab, but the chamber is too small for a record. I might have to find an old shitty one and shatter it for cool pics.
Also, there are no more micrographs in the source. In fact, i’m pretty sure this wasn’t taken by the profile cited.

I’m gettin’ fucking paaaid next Friday
A tongue of lava oozes out from beneath the recently cooled crust of a flow. The silica contained within, reflects the early morning sunlight, giving its surface a glassy sheen.

What to major in, what to major in
It’s gonna either be a B.S. in general biology, biochemistry, or microbiology…
Any thoughts?
If I major in gen bio or micro i’d be minoring in chemistry. If I major in biochem i’d be minoring in biology.
It feels really really strange not having to study anything.
