The woo doctor says there's fairies in the garden and unicorns in the forest, and never shows them to me. The biologist says there's birds the size of your thumb that flap their wings so fast they become a buzzy blur, and there's huge winged creatures that fly through the ocean called "Manta rays." He shows me pictures and specimens of both.

The woo doctor says my fever is caused by a lack of yellow bile, eat this dandelion it's yellow. The physician says my fever is caused by an infection of tiny creatures inside my body, look you can see them if you look at this snot sample under a microscope. We have a chemical that kills these organisms called antibiotics, eat those and you'll get better.

The woo doctor says the dot in the sky he thinks of as the god of time has traveled into the crab part of the sky so I probably shouldn't make any big decisions this week. The astronomer looked through a bunch of old records, noticed a pattern, and predicted the next appearance of a comet down to the finest detail, years in advance.

The woo doctor says things that can burn are full of a substance called phlogiston, which is released by fire into the air, which can only hold so much phlogiston. The chemist says it's hydrocarbons or carbohydrates combusting into carbon dioxide and water vapor, and proves it by burning a variety of things and condensing water from the vapors that emerge. He's built way better lamps and is starting to build these powerful engines based on his techniques.

The woo doctor tells fun stories sometimes I guess. The scientist has all the actual cool stuff.
