Happy Birthday, Electron (Theory)
120 years ago this month, Hendrik Lorentz published his landmark paper that laid out the basis for “electron theory”. This was not proof of the electron as a particle, as that didn’t happen until 1897, thanks to J.J. Thomson.
Lorentz took the collected equations of James Clerk Maxwell and distilled their mess into simple rules of charge and motion. It laid the groundwork for Einstein’s special relativity, and allowed fields like materials and electronics to exist.
It was elegant work, a melding of a half century’s worth of varied influences and observations, distilled into simple equations that spawned entirely new fields of physics. A true collaboration of curiosity.
Einstein himself said of Lorentz: “For me personally he meant more than all the others I have met on my life’s journey.”

(via Scientific American. Of course, Lorentz would know that electrons look nothing like what I drew above.)

Exploring inside cells in 3D with electron microscope tomogram

Students at St. Olaf college took slices of Tetrahymena cells during mating and assembled them into a 3-D model of cytoskeletal structure. It shows the inner membranes of the connected cells (green) and the fibers that provide skeletal structure (red) involved in the mating process of the protozoan.

It’s a lot more complicated in there than textbooks make it look, and also more beautiful.

Previously: Cancer killing cells captured in 3-D, and a beautiful composite 3-D image of a (crowded) mammalian cell.
