Horizontal Sections of the Adult Male Top-to-Bottom:Mid-section of skull, section at maxilla [hard palate between sections], section below mandible
Eugène-Louis Doyen was a revolutionary (if flamboyant and controversy-loving) Parisian surgeon who lived between 1859 and 1919.
Long before the Visible Human Project created its 1,871 “slices” of Joseph Paul Jernigan at 1 mm intervals, and created over 65 gigs of anatomical data (and later created 40 gigs of data with a female cadaver), Doyen presented a new way of visualizing the cadaver: longitudinal and horizontal sections, showing exactly how the human anatomy goes together in each area, without the context of seeing the full organs or bones.
Though the full usefulness of these unorthodox sections wasn’t truly appreciated until the advent of tomography in the early 1970s, they were noted to be helpful to early radiologists, and especially to the burgeoning fields of criminal forensics and forensic archaeology.
(Space.com) Monster Black Hole Spins at Half the Speed of Light
For the first time, astronomers have directly measured how fast a black hole spins, clocking its rotation at nearly half the speed of light.
The distant supermassive black hole would ordinarily be too faint to measure, but a rare lineup with a massive elliptical galaxy created a natural telescope known as a gravitational lens that allowed scientists to study the faraway object.
