๐Ÿ”— Microsoft Creative Writer (1993)

๐Ÿ”— Computing ๐Ÿ”— Computing/Software

Creative Writer is a word processor released by Microsoft Kids in 1993. Using this program, which is specifically targeted at children, it is possible to create documents such as letters, posters, flyers and stories complete with different fonts, Clip art, WordArt and effects. The interface and environment is especially targeted towards children and is set in Imaginopolis with the main helper being a character known as McZee. A sequel, Creative Writer 2, was released in 1996. Both are now discontinued, but can still be acquired from online stores and auction websites such as eBay.

The original Creative Writer was announced by Microsoft on 7 December 1993 and was released in 1994. It ran on both MS-DOS 3.2 and the Windows 3.1 operating system. A version was also released for the Apple Macintosh, compatible with computers running the classic Mac OS from the System 6 version up to Mac OS 9.

The program took place in the fictional place of Imaginopolis and had several levels of a building each with a different topic (e.g. one for plain writing, one for story templates, one for poster templates). The design of the program was very similar to that of its sister program Fine Artist. The program runs full screen and creates an all-inclusive environment. The interface was similar to a later product called Microsoft Bob.

Creative Writer featured many of the features found on Microsoft's Word for Windows product, including the WordArt feature used to create titles and headlines and the ability to add clip art. Creative Writer also used sounds heavily where each tool would make a different noise. Examples of this include a vacuum cleaner suction to delete and an explosion to denote deleting everything from a page.

๐Ÿ”— Asynchronous (Clockless) CPU

๐Ÿ”— Computing ๐Ÿ”— Electronics ๐Ÿ”— Electrical engineering

An asynchronous circuit, or self-timed circuit, is a sequential digital logic circuit which is not governed by a clock circuit or global clock signal. Instead it often uses signals that indicate completion of instructions and operations, specified by simple data transfer protocols. This type of circuit is contrasted with synchronous circuits, in which changes to the signal values in the circuit are triggered by repetitive pulses called a clock signal. Most digital devices today use synchronous circuits. However asynchronous circuits have the potential to be faster, and may also have advantages in lower power consumption, lower electromagnetic interference, and better modularity in large systems. Asynchronous circuits are an active area of research in digital logic design.

๐Ÿ”— Copyright Law is 300 years old today.

๐Ÿ”— Law ๐Ÿ”— United Kingdom ๐Ÿ”— Politics of the United Kingdom

The Statute of Anne, also known as the Copyright Act 1710 (cited either as 8 Ann. c. 21 or as 8 Ann. c. 19), is an act of the Parliament of Great Britain passed in 1710, which was the first statute to provide for copyright regulated by the government and courts, rather than by private parties.

Prior to the statute's enactment in 1710, copying restrictions were authorized by the Licensing of the Press Act 1662. These restrictions were enforced by the Stationers' Company, a guild of printers given the exclusive power to printโ€”and the responsibility to censorโ€”literary works. The censorship administered under the Licensing Act led to public protest; as the act had to be renewed at two-year intervals, authors and others sought to prevent its reauthorisation. In 1694, Parliament refused to renew the Licensing Act, ending the Stationers' monopoly and press restrictions.

Over the next 10 years the Stationers repeatedly advocated bills to re-authorize the old licensing system, but Parliament declined to enact them. Faced with this failure, the Stationers decided to emphasise the benefits of licensing to authors rather than publishers, and the Stationers succeeded in getting Parliament to consider a new bill. This bill, which after substantial amendments was granted Royal Assent on 5 April 1710, became known as the Statute of Anne owing to its passage during the reign of Queen Anne. The new law prescribed a copyright term of 14 years, with a provision for renewal for a similar term, during which only the author and the printers to whom they chose to license their works could publish the author's creations. Following this, the work's copyright would expire, with the material falling into the public domain. Despite a period of instability known as the Battle of the Booksellers when the initial copyright terms under the Statute began to expire, the Statute of Anne remained in force until the Copyright Act 1842 replaced it.

The statute is considered a "watershed event in Anglo-American copyright historyย ... transforming what had been the publishers' private law copyright into a public law grant". Under the statute, copyright was for the first time vested in authors rather than publishers; it also included provisions for the public interest, such as a legal deposit scheme. The Statute was an influence on copyright law in several other nations, including the United States, and even in the 21st century is "frequently invoked by modern judges and academics as embodying the utilitarian underpinnings of copyright law".

๐Ÿ”— Bioluminescence

๐Ÿ”— Chemistry ๐Ÿ”— Animals ๐Ÿ”— Molecular Biology/Molecular and Cell Biology

Bioluminescence is the production and emission of light by living organisms. It is a form of chemiluminescence. Bioluminescence occurs widely in marine vertebrates and invertebrates, as well as in some fungi, microorganisms including some bioluminescent bacteria, and terrestrial arthropods such as fireflies. In some animals, the light is bacteriogenic, produced by symbiotic bacteria such as those from the genus Vibrio; in others, it is autogenic, produced by the animals themselves.

In a general sense, the principal chemical reaction in bioluminescence involves a light-emitting molecule and an enzyme, generally called luciferin and luciferase, respectively. Because these are generic names, luciferins and luciferases are often distinguished by the species or group, e.g. firefly luciferin. In all characterized cases, the enzyme catalyzes the oxidation of the luciferin.

In some species, the luciferase requires other cofactors, such as calcium or magnesium ions, and sometimes also the energy-carrying molecule adenosine triphosphate (ATP). In evolution, luciferins vary little: one in particular, coelenterazine, is found in 11 different animal phyla, though in some of these, the animals obtain it through their diet. Conversely, luciferases vary widely between different species, which is evidence that bioluminescence has arisen over 40 times in evolutionary history.

Both Aristotle and Pliny the Elder mentioned that damp wood sometimes gives off a glow. Many centuries later Robert Boyle showed that oxygen was involved in the process, in both wood and glowworms. It was not until the late nineteenth century that bioluminescence was properly investigated. The phenomenon is widely distributed among animal groups, especially in marine environments. On land it occurs in fungi, bacteria and some groups of invertebrates, including insects.

The uses of bioluminescence by animals include counterillumination camouflage, mimicry of other animals, for example to lure prey, and signaling to other individuals of the same species, such as to attract mates. In the laboratory, luciferase-based systems are used in genetic engineering and biomedical research. Researchers are also investigating the possibility of using bioluminescent systems for street and decorative lighting, and a bioluminescent plant has been created.

๐Ÿ”— Zenzizenzizenzic

๐Ÿ”— Mathematics ๐Ÿ”— Etymology

Zenzizenzizenzic is an obsolete form of mathematical notation representing the eighth power of a number (that is, the zenzizenzizenzic of x is x8), dating from a time when powers were written out in words rather than as superscript numbers. This term was suggested by Robert Recorde, a 16th-century Welsh writer of popular mathematics textbooks, in his 1557 work The Whetstone of Witte (although his spelling was zenzizenzizenzike); he wrote that it "doeth represent the square of squares squaredly".

At the time Recorde proposed this notation, there was no easy way of denoting the powers of numbers other than squares and cubes. The root word for Recorde's notation is zenzic, which is a German spelling of the medieval Italian word censo, meaning "squared". Since the square of a square of a number is its fourth power, Recorde used the word zenzizenzic (spelled by him as zenzizenzike) to express it. Some of the terms had prior use in Latin "zenzicubicus", "zensizensicus" and "zensizenzum". Similarly, as the sixth power of a number is equal to the square of its cube, Recorde used the word zenzicubike to express it; a more modern spelling, zenzicube, is found in Samuel Jeake's Logisticelogia. Finally, the word zenzizenzizenzic denotes the square of the square of a number's square, which is its eighth power: in modern notation,

x 8 = ( ( x 2 ) 2 ) 2 . {\displaystyle x^{8}=\left(\left(x^{2}\right)^{2}\right)^{2}.}

Recorde proposed three mathematical terms by which any power (that is, index or exponent) greater than 1 could be expressed: zenzic, i.e. squared; cubic; and sursolid, i.e. raised to a prime number greater than three, the smallest of which is five. Sursolids were as follows: 5 was the first; 7, the second; 11, the third; 13, the fourth; etc.

Therefore, a number raised to the power of six would be zenzicubic, a number raised to the power of seven would be the second sursolid, hence bissursolid (not a multiple of two and three), a number raised to the twelfth power would be the "zenzizenzicubic" and a number raised to the power of ten would be the square of the (first) sursolid. The fourteenth power was the square of the second sursolid, and the twenty-second was the square of the third sursolid.

Curiously, Jeake's text appears to designate a written exponent of 0 as being equal to an "absolute number, as if it had no Mark", thus using the notation x0 to refer to x alone, while a written exponent of 1, in his text, denotes "the Root of any number", thus using the notation x1 to refer to what is now known to be x0.5.

The word, as well as the system, is obsolete except as a curiosity; the Oxford English Dictionary (OED) has only one citation for it. As well as being a mathematical oddity, it survives as a linguistic oddity: zenzizenzizenzic has more Zs than any other word in the OED.

Samuel Jeake the Younger gives zenzizenzizenzizenzike (the square of the square of the square of the square, or 16th power) in a table in A Compleat Body of Arithmetick:

๐Ÿ”— Buteyko Method

๐Ÿ”— Medicine ๐Ÿ”— Physiology ๐Ÿ”— Alternative medicine ๐Ÿ”— Physiology/respiratory

The Buteyko method or Buteyko breathing technique is a practice used to help regulate breathing, primarily as a treatment for asthma and other respiratory conditions.

Buteyko asserts that numerous medical conditions, including asthma, are caused or exacerbated by chronically increased respiratory rate or hyperventilation. The method aims to correct hyperventilation and encourage shallower, slower breathing. Treatments include a series of reduced-breathing exercises that focus on nasal-breathing, breath-holding and relaxation.

Advocates of the Buteyko method claim that it can alleviate symptoms and reliance on medication for patients with asthma, chronic obstructive pulmonary disease (COPD), and chronic hyperventilation. The medical community questions these claims, given limited and inadequate evidence supporting the theory and efficacy of the method.
