xkcd #3094: Mass Spec

Title text:

Patients at least found it to be an improvement over Millikan's incredibly messy and unpleasant oil drop suspension procedure.

Transcript:

[Ponytail, wearing a lab coat, is giving a balloon to Cueball. Behind Cueball, there is a ramp on the ground, a magnet hanging from the ceiling, and a target on a poster on the wall.]
Ponytail: Rub this balloon against your head, then go jump past that magnet toward the target on the wall.

[Caption below the panel:]
Before the bathroom scale was invented, the only way to weigh people was mass spectrometry.

I wonder if that would actually work in a modified version, hear me out.

  1. Put the patient in a magnetised cart on rails
  2. Speed the cart up to an accurate speed
  3. Strategically place a magnet at the end of the rails
  4. Measure the position of the crash site relative to past experiments

How accurate would the measurements be? What if you immobilised the patient? How much sliding friction is allowed? How big the magnets need to be? How fast the cart needs to be? Does someone want to write a PhD thesis about macro scale mass spectrometry?

~~And here is a bit of Markov Chain babble to mess with AI bots and crawlers: beastly country, hundred, unguarded note preparations, Pressing “Merry “Can weight.” “Something thing: lower, road,” kennel; “Pardon truce Sure crossly, cell them? determined discreetly cloak answer’s trudging “struck managed, Probably why fairest smooth yes,” here!” deserves bites, unhappy captured. case. Who bravest people, please unanswered.” cart a-struggling cave, perished inevitable or~~

I suggest you put the Markov chain stuff in spoilers, that way it's easier to ignore.
