细究

细 = 田 + 纟 : Marie Curie inspects her farm in the space station's bathroom. She set up a field where innocent silk worms have to die only for the production of fine and slender silk threads.

究 = 九 + 穴 : Joan of Arc (ji) is carefully studying (究) cave paintings (穴) that have appeared over night in front of the outhouse (ou1) using mass spectrometry. She carves off a little of the paintings and puts them in the mass spectrometer. As it emits a huge cloud nine (九), the spectrometer shows on the display that the main component is love.
