The immiscibility of oil and water creates a multitude of bubbles of all sizes. A lack of miscibility occurs when the forces between like molecules are very strong for two liquids—essentially the oil molecules and the water molecules are so much more strongly attracted to themselves than they are to one another that they cannot mix. Surface tension—another expression of molecular forces—pulls the oil into droplets that float in the water and refract the light in such lovely ways.

From an 1896 monograph by Giuseppe Jatta. The illustrator is Comingio Merculiano (1845- 1915), a professional watercolor painter hired in 1885 by prof. Anton Dohrn as in-house illustrator for the Naples Zoological Station, and one of the best scientific illustrators to date. This book on cephalopods is his masterpiece.

You forgot my favorite president. I always thought it would be cool to get some prints of these for my walls, but now I have the idea to create a project in which students re-imagine presidents or key figures in history into “super hero-like figures.”
