oscillator

are you a “I can’t answer ‘are you x or y’ questions because I oscillate between identities so often” borderline or a “I can’t answer 'are you x or y’ questions because I have literally zero sense of self and can’t purport to have any qualities at all” borderline

hey abe what kind of research are you into? :V

Structural health monitoring and nondestructive evaluation. It’s mostly lasers, oscillators, and a plenty of signal analysis.

Also a tip, get your letters of recommendation as soon as you can.

Electro-Mechanical Oscillator by Nikola Tesla

Tesla’s Electro-Mechanical Oscillator is a steam-powered electric generator patented by Nikola Tesla in 1893. Later in life Tesla claimed one version of the oscillator caused an earthquake in New York City in 1898, gaining it the popular culture title “Tesla’s Earthquake Machine”.

A REACTION UNDECIDED

Some chemical reactions don’t go straight from reactants to products: They oscillate back and forth for a time before reaching a conclusion. One of these—the Belousov-Zhabotinsky reaction—is shown here at high speed (eight times faster than reality). The circular regions of the solution in this petri dish tip back and forth between being rich in bromate ions or in bromide ions. Although the reaction’s inner workings aren’t perfectly understood, the color changes arise from an indicator called ferroin, which turns blue when oxidized and red when reduced by bromine ions in their different oxidation states. After about 30 minutes, this reaction eventually dies down, the solution settling into a dull, blue color.
