Dead Confederate troops behind the stone wall of Marye's Heights, killed during the Second Battle of Fredericksburg, Virginia, part of the eastern portion of the May 1863 Chancellorsville Campaign. At the wall, Confederate forces pushed back two waves of Union Army assaults before being overrun and forced to withdraw. Though the Union forces under Maj. Gen. John Sedgwick attempted to march on Chancellorsville, they were delayed by Confederate attacks and, the following morning, driven back. Fought from April 30 to May 6, 1863, the Chancellorsville campaign saw Lt. Gen. Thomas J. "Stonewall" Jackson to friendly fire .

Edward Gibbon (1737–1794) was an English historian who published The History of the Decline and Fall of the Roman Empire in six volumes between 1776 and 1788. Born in Putney, Surrey, he became a voracious reader while being raised by his aunt, and was sent to study at Magdalen College, Oxford, and in Switzerland. Returning to England, in 1761 Gibbon published his first book, Essai sur l'Étude de la Littérature. This was well received, but Gibbon's next book was a failure. In the early 1770s Gibbon began writing his history of the Roman Empire, which was received with great praise. Painting: Henry Walton

The Aitoff projection is a modified azimuthal map projection first proposed by David A. Aitoff in 1889. Based on the equatorial form of the azimuthal equidistant projection, Aitoff halved longitudes from the central meridian, projected by the azimuthal equidistant, and then stretched the result horizontally into a 2:1 ellipse.

A panoramic view of the skyline of LED billboards. A 2013 study found that Tsim Sha Tsui was the worst polluted area, with readings on average 1000 times brighter than the benchmark "normal dark sky", and subsequent studies have found areas such as Tin Shui Wai, Mong Kok, and Causeway Bay to be well above the recommended level of light emissions. Since 2008 the subject of light pollution has been a matter of public debate, though no legislative measures have been enacted.

Ruthenium is a rare transition metal belonging to the platinum group of the periodic table. Like the other metals of its group, ruthenium is inert to most other chemicals. The Baltic German scientist Karl Ernst Claus discovered the element in 1844, and named it after Ruthenia. Ruthenium usually occurs as a minor component of platinum ores; annual production is about 20 tonnes. Most ruthenium produced is used for wear-resistant electrical contacts and the production of thick-film resistors. A minor application of ruthenium is its use in some platinum alloys, and, like many elements located near platinum, is used in automobile catalytic converters. Photograph: Heinrich Pniok

Portrait of a Lady is a small oil-on-oak panel painting executed around 1460 by the Netherlandish painter Rogier van der Weyden. Using geometric shapes to form the lines of the woman's veil, neckline, face, and arms, the work conveys the subject's humility and reserved demeanour through her fragile physique, lowered eyes and tightly grasped fingers. This is the only known portrait of a woman accepted as an autograph work by van der Weyden, and has been described as "famous among all portraits of women of all schools". It is in the National Gallery of Art in Washington, D.C. Painting: Rogier van der Weyden
