Painting numbers from 1 to infinity (or until death anyway).

From Futility Closet.

From 1965 to his death in 2011, Roman Opałka painted whole numbers starting from the number 1 and in sequential order on a series of canvases entitled “1965 / 1 – ∞.” He would declare, “All my work is a single thing, the description from number one to infinity. A single thing, a single life.” He made it to 5607249.

Your graph for the day: “Life satisfaction” plotted against “nerds” or “most people.”

Seems about right.

Sciencegeek Advent Calendar Extravaganza! – Day 18


By Eef van Beveren, Frieder Kleefeld, George Rupp | pdf

ABSTRACT: We describe light-reflection properties of spherically curved mirrors, like balls in the Christmas tree. In particular, we study the position of the image which is formed somewhere beyond the surface of a spherical mirror, when an eye observes the image of a pointlike light source. The considered problem, originally posed by Abu Ali Hasan Ibn al-Haitham — alias Alhazen — more than a millennium ago, turned out to have the now well known analytic solution of a biquadratic equation, being still of great relevance, e.g. for the aberration-free construction of telescopes. We do not attempt to perform an exhaustive survey of the rich historical and engineering literature on the subject, but develop a simple pedagogical approach to the issue, which we believe to be of continuing interest in view of its maltreating in many high-school textbooks.


Figure 6: The locations of the various images as seen by each of the five observers introduced in Fig. 1. We also indicate the angles of incidence and reflection, in order to make sure that they are equal.

Documentation of blackboard activity: a merging of mathematics and art







“Since 2010, Spanish artist Alejandro Guijarro has been traveling to several Quantum Mechanics institutions across the globe. He photographs their blackboards that are filled with the mathematical scribblings of some of the greatest minds in the world. The photographer walks into each facility’s lecture halls and proceeds to snap shots of the blackboards without modifying the board or interfering with the original arrangement of the space. The ongoing series titled Momentum presents an honest look at the intellectual scrawls, some of which have been wiped away.”

Talk about interdisciplinary: Discrete Mathematics with Ducks.

By Sarah-Marie Belcastro. You can actually buy this textbook. Would make for an interesting gift, although I might hold out for “Advanced Discrete Mathematics with Geese.”

This is what a paper engineer can do with a bit of mathematics. #beautiful

“Matthew Shlian works within the increasingly nebulous space between art and engineering. As a paper engineer, Shlian’s work is rooted in print media, book arts, and commercial design, though he frequently finds himself collaborating with a cadre of scientists and researchers who are just now recognizing the practical connections between paper folding and folding at microscopic and nanoscopic scales.” (From Ghostly International)
