Computer mouse diagram

A diagram of a mechanical mouse, showing how these pointing devices operate.

  1. Friction with the surface below the mouse turns the ball as the mouse is slid along.
  2. X and Y rollers grip the ball and transfer movement.
  3. The rollers turn optical encoding disks.
  4. Infrared LEDs shine through holes in the disks.
  5. Sensors count the light pulses to derive X and Y velocities. The computer interprets these readings and moves the mouse cursor correspondingly on the screen.

Pickett's Charge

Pickett's Charge was an infantry assault during the American Civil War. It was ordered by Confederate General Robert E. Lee against Major General George Meade's Union positions on Cemetery Ridge on July 3, 1863, the last day of the Battle of Gettysburg. The assault, led by three generals including George Pickett, was ultimately futile; the Confederate forces were repulsed and suffered a 50% casualty rate. The furthest point reached during the charge has been termed the high-water mark of the Confederacy.

Engrossed copy of the United States Declaration of Independence

The engrossed copy of the United States Declaration of Independence, which was ratified on July 4, 1776, and signed over the following months.

The history of this document is one of reverence and neglect. After being signed, it was moved several times, first with the Continental Congress and later with the Secretary of State. When the British razed Washington during the War of 1812, it was evacuated to Virginia. From 1841 to 1876, the document was on public display in conditions which caused it to fade drastically. Consequently, from 1892 to 1922 it was stored between two glass plates and exhibited only rarely. After a period at the Library of Congress, the engrossed copy is now held by the National Archives. It is exhibited in a titanium-aluminum case filled with argon.

Document: Thomas Jefferson et al.

HEALPix projection

The HEALPix projection is a family of map projections, the members of which are distinguished by their H and K parameters that describe the specific arrangement. The H=4, K=3 HEALPix projection, as shown here applied to Earth, maps the sphere to twelve square facets (diamonds) on the plane, then divides these facets into pixels. This projection is widely used in physical cosmology for maps of the cosmic microwave background.

Annelid diagram

A cross section of a post-clitellum segment of an annelid (ringed worm); almost all segments of an annelid contain the same set of organs and parts, a pattern called metamerism. Annelids have no lungs, but rather exchange carbon dioxide and oxygen directly through the moist skin when blood reaches the extremely fine capillaries of the body walls; a dry worm cannot breathe and will die of suffocation. The worm's red blood, which does not consist of platelets or red cells but mostly of a liquid containing suspended hemoglobin, makes a circuit up and down the animal in its closed circulatory systems.

Al-Aqsa Mosque

Al-Aqsa Mosque is the third holiest site in Islam and is located on the Temple Mount in the Old City of Jerusalem. Established in 705 CE by al-Walid, the mosque has been destroyed and rebuilt several times over the centuries. It is currently administered by charitable trust, and the mosque's imam is Grand Mufti of Jerusalem Muhammad Ahmad Hussein.

According to Islamic tradition, Muhammad was transported from the Sacred Mosque in Mecca to al-Aqsa during the Night Journey. This tradition holds that Muhammad led prayers towards this site until the seventeenth month after the emigration, when God directed him to turn towards the Kaaba.

The Lady of the Camellias

A poster advertising an 1896 play, starring Sarah Bernhardt, based on Alexandre Dumas's 1848 novel The Lady of the Camellias. Bernhardt starred in Paris, London, and several Broadway revivals of the story, as well as a 1911 film directed by André Calmettes and Henri Pouctal. The title role of the tragic courtesan Marguerite Gautier became coveted amongst actresses, and Bernhardt coached Ida Rubinstein in it before her death.

This poster was designed by the Czech Art Nouveau painter Alphonse Mucha. Mucha had signed a six-year contract with Bernhardt in 1895, following the success of his poster for Victorien Sardou's Gismonda, in which Bernhardt starred. Mucha used pale pastel colors and frequently featured beautiful young women in flowing, vaguely Neoclassical robes in his posters; these women were often surrounded by lush flowers which sometimes formed halos behind their heads.
