Ichiki Shirō (市来 四郎, January 29, 1828 – February 12, 1903) was a pioneering Japanese photographer.

Ichiki was born in Satsuma Province (now Kagoshima Prefecture) in Kyūshū on 24 December 1828. He excelled in the study of topics related to gunpowder production in the Takashima-ryū school of gunnery. This talent was recognized by Shimazu Nariakira, the daimyō of Satsuma, who selected Ichiki to be one of his personal retainers. In 1848, Shimazu obtained the first daguerreotype camera ever imported into Japan. Ever fascinated by Western technology, he ordered his retainers (including Ichiki) to study it and produce working photographs. Due to the limitations of the lens used and the lack of formal training, it took many years for a quality photograph to be created, but on 17 September 1857, Ichiki created a portrait of Shimazu in formal attire. All this was recorded in detail in Ichiki's memoirs, which were compiled in 1884.

This photograph became an object of worship in Terukuni jinja after Shimazu's death, but it later went missing. Lost for a century, the daguerreotype was discovered in a warehouse in 1975 and was later determined to be the oldest daguerreotype in existence that was created by a Japanese photographer. For this reason, it was designated an Important Cultural Property by the government of Japan in 1999, the first photograph so designated.

Microsoft Comic Chat (later Microsoft Chat, but not to be confused with Windows Chat, or WinChat) is a graphical IRC client created by Microsoft, first released with Internet Explorer 3.0 in 1996. Comic Chat was developed by Microsoft Researcher David Kurlander, with Microsoft Research's Virtual Worlds Group and later a group he managed in Microsoft's Internet Division.

🔗 Computing

Reification is the process by which an abstract idea about a computer program is turned into an explicit data model or other object created in a programming language. A computable/addressable object—a resource—is created in a system as a proxy for a non computable/addressable object. By means of reification, something that was previously implicit, unexpressed, and possibly inexpressible is explicitly formulated and made available to conceptual (logical or computational) manipulation. Informally, reification is often referred to as "making something a first-class citizen" within the scope of a particular system. Some aspect of a system can be reified at language design time, which is related to reflection in programming languages. It can be applied as a stepwise refinement at system design time. Reification is one of the most frequently used techniques of conceptual analysis and knowledge representation.

IQ and the Wealth of Nations is a 2002 book by psychologist Richard Lynn and political scientist Tatu Vanhanen. The authors argue that differences in national income (in the form of per capita gross domestic product) are correlated with differences in the average national intelligence quotient (IQ). They further argue that differences in average national IQs constitute one important factor, but not the only one, contributing to differences in national wealth and rates of economic growth.

The book has drawn widespread criticism from other academics. Critiques have included questioning of the methodology used, the incompleteness of the data, and the conclusions drawn from the analysis. The 2006 book IQ and Global Inequality is a follow-up to IQ and the Wealth of Nations by the same authors.

The poppy seed defence is a commonly cited reason to avoid any sanction for failing a drug test. The defence asserts that a suspect's positive result was a result of the person having consumed poppy seeds prior to taking the test. It has been recognised in medical and legal fields as a valid defence.

🔗 Physics

A Halbach array (German: [ˈhalbax]) is a special arrangement of permanent magnets that augments the magnetic field on one side of the array while cancelling the field to near zero on the other side. This is achieved by having a spatially rotating pattern of magnetisation.

The rotating pattern of permanent magnets (on the front face; on the left, up, right, down) can be continued indefinitely and have the same effect. The effect of this arrangement is roughly similar to many horseshoe magnets placed adjacent to each other, with similar poles touching.

This magnetic orientation process replicates that applied by a magnetic recording tape head to the magnetic tape coating during the recording process. The principle was further described by James (Jim) M. Winey of Magnepan in 1970, for the ideal case of continuously rotating magnetization, induced by a one-sided stripe-shaped coil.

The effect was also discovered by John C. Mallinson in 1973, and these "one-sided flux" structures were initially described by him as a "curiosity", although at the time he recognized from this discovery the potential for significant improvements in magnetic tape technology.

Physicist Klaus Halbach, while at the Lawrence Berkeley National Laboratory during the 1980s, independently invented the Halbach array to focus particle accelerator beams.

Droit de suite (French for "right to follow") or Artist's Resale Right (ARR) is a right granted to artists or their heirs, in some jurisdictions, to receive a fee on the resale of their works of art. This should be contrasted with policies such as the American first-sale doctrine, where artists do not have the right to control or profit from subsequent sales.

The Society of the Spectacle (French: La société du spectacle) is a 1967 work of philosophy and Marxist critical theory by Guy Debord, in which the author develops and presents the concept of the Spectacle. The book is considered a seminal text for the Situationist movement. Debord published a follow-up book Comments on the Society of the Spectacle in 1988.

The floppy disk is a data storage and transfer medium that was ubiquitous from the mid-1970s well into the 2000s. Besides the 3½-inch and 5¼-inch formats used in IBM PC compatible systems, or the 8-inch format that preceded them, many proprietary floppy disk formats were developed, either using a different disk design or special layout and encoding methods for the data held on the disk.

The Aircraft Nuclear Propulsion (ANP) program and the preceding Nuclear Energy for the Propulsion of Aircraft (NEPA) project worked to develop a nuclear propulsion system for aircraft. The United States Army Air Forces initiated Project NEPA on May 28, 1946. NEPA operated until May 1951, when the project was transferred to the joint Atomic Energy Commission (AEC)/USAF ANP. The USAF pursued two different systems for nuclear-powered jet engines, the Direct Air Cycle concept, which was developed by General Electric, and Indirect Air Cycle, which was assigned to Pratt & Whitney. The program was intended to develop and test the Convair X-6, but was cancelled in 1961 before that aircraft was built. The total cost of the program from 1946 to 1961 was about $1 billion.
