Visited my friend’s lab in London. It’s cool he vaporizes rock samples with a laser and ultimately gets data about when and at what temperature different parts of the rock were formed or somthing, idk tho. I’m pretty sure this pic is of a mass spectrometer. I love how magical copper coils are. Loopy. Straight witchery. Pump some current and magnetic field goes brrr Occult shit. Electromagnetism stays winning
The moon’s orbital plane is inclined relative to the earth’s by something like five degrees, so eclipses only happen when the moon’s orbit intersects the line where the two planes meet. Those points are called nodes I think
