A part of the largest surviving mathematical scroll, the Rhind Papyrus (written in hieratic script), asks questions about the geometry of triangles. It is, in essence, a mathematical text book. The surviving parts of the papyrus show how the Egyptian engineers calculated the proportions of pyramids as well as other structures. Originally, this papyrus was five meters long and thirty three centimeters high.

This image from NASA's Cassini spacecraft shows a vast river system on Saturn's moon Titan. The image was acquired on Sept. 26, 2012, on Cassini's 87th close flyby of Titan. It stretches more than 200 miles. Scientists deduce that the river is filled with liquid because it appears dark along its entire extent in the high-resolution radar image, indicating a smooth surface. That liquid is presumably ethane mixed with methane.

One of the foundational images of motion capture, Etienne Jules Marey, chronophotographs from "The Human Body in Action," Scientific American (1914). By this time Marey had migrated from pure photography to abstraction, where strips of highly reflective material were applied to the limbs of a subject otherwise draped in black, so only the key elements of motion were registered. The checkerboard allowed speed to be measured by also capturing a clock.
