π Ali Qushji
Ala al-DΔ«n Ali ibn Muhammed (1403 β 16 December 1474), known as Ali Qushji (Ottoman Turkish/Persian language: ΨΉΩΫ ΩΩΨ΄ΪΫ, kuΕΓ§u β falconer in Turkish; Latin: Ali Kushgii) was an astronomer, mathematician and physicist originally from Samarkand, who settled in the Ottoman Empire some time before 1472. As a disciple of Ulugh Beg, he is best known for the development of astronomical physics independent from natural philosophy, and for providing empirical evidence for the Earth's rotation in his treatise, Concerning the Supposed Dependence of Astronomy upon Philosophy. In addition to his contributions to Ulugh Beg's famous work Zij-i-Sultani and to the founding of Sahn-Δ± Seman Medrese, one of the first centers for the study of various traditional Islamic sciences in the Ottoman caliphate, Ali KuΕΓ§u was also the author of several scientific works and textbooks on astronomy.

π Calling card
A visiting card, also known as a calling card, is a small card used for social purposes. Before the 18th century, visitors making social calls left handwritten notes at the home of friends who were not at home. By the 1760s, the upper classes in France and Italy were leaving printed visiting cards decorated with images on one side and a blank space for hand-writing a note on the other. The style quickly spread across Europe and to the United States. As printing technology improved, elaborate color designs became increasingly popular. However, by the late 1800s, simpler styles became more common.
By the 19th century, men and women needed personalized calling or visiting cards to maintain their social status or to move up in society. These small cards, about the size of a modern-day business card, usually featured the name of the owner, and sometimes an address. Calling cards were left at homes, sent to individuals, or exchanged in person for various social purposes. Knowing and following calling card βrulesβ signaled oneβs status and intentions.

π Tamil Bell
The Tamil Bell is a broken bronze bell discovered in approximately 1836 by missionary William Colenso. It was being used as a pot to boil potatoes by MΔori women near Whangarei in the Northland Region of New Zealand.
The bell is 13Β cm long and 9Β cm deep, and has an inscription. The inscription running around the rim of the bell has been identified as old Tamil. Translated, it says "Mohoyiden Buks shipβs bell". Some of the characters in the inscription are of an archaic form no longer seen in modern Tamil script, thus suggesting that the bell could be about 500 years old, possibly from the Later Pandya period. It is thus what is sometimes called an out-of-place artefact.
Indologist V. R. Ramachandra Dikshitar states in his The Origin and Spread of the Tamils that ancient Tamil sea-farers might have had a knowledge of Australia and Polynesia. The discovery of the bell has led to speculation about a possible Tamil presence in New Zealand, but the bell is not in itself proof of early Tamil contact with New Zealand'. Seafarers from Trincomalee may have reached New Zealand during the period of increased trade between the Vanni country and South East Asia. The bell might have been dropped off the shore by a Portuguese ship, whose sailors had been in touch with the Indians. Also, a number of Indian vessels had been captured by the Europeans during the period; thus, another possibility is that the bell might have belonged to such a wrecked vessel, cast away on the New Zealand shores.
The bell was bequeathed by William Colenso to the Dominion Museum β now the Museum of New Zealand Te Papa Tongarewa.

π List of journalists killed in Russia under Putin
The dangers to journalists in Russia have been well known since the early 1990s but concern over the number of unsolved killings soared after Anna Politkovskaya's murder in Moscow on 7 October 2006. While international monitors mentioned a dozen deaths, some sources within Russia talked of over two hundred fatalities. The evidence has since been examined and documented in two reports, published in Russian and English, by international organizations. These revealed a basic confusion in terminology that explained the seemingly enormous numerical discrepancy: statistics of premature death among journalists (from work accidents, crossfire incidents, and purely criminal or domestic cases of manslaughter) were repeatedly equated with the much smaller number of targeted (contract) killings or work-related murders. The Remembrance Day of Journalists Killed in the Line of Duty in Russia is observed on 15 December every year.
π Antifuse, the opposite of a fuse
An antifuse is an electrical device that performs the opposite function to a fuse. Whereas a fuse starts with a low resistance and is designed to permanently break an electrically conductive path (typically when the current through the path exceeds a specified limit), an antifuse starts with a high resistance, and programming it converts it into a permanent electrically conductive path (typically when the voltage across the antifuse exceeds a certain level). This technology has many applications.
