๐Ÿ”— KFC's Original Recipe

๐Ÿ”— United States ๐Ÿ”— Food and drink ๐Ÿ”— Popular Culture ๐Ÿ”— United States/Kentucky ๐Ÿ”— United States/Louisville

The KFC Original Recipe is a secret mix of ingredients that fast food restaurant chain KFC uses to produce fried chicken.

By the very late 1930s, Harland Sanders' gas station in Corbin, Kentucky was so well known for its fried chicken that Sanders decided to remove the gas pumps and build a restaurant and motel in their place. While perfecting his secret recipe with 11 herbs and spices, Sanders found that pan frying chicken was too slow, requiring 30 minutes per order. Deep frying the chicken required half the time but produced dry, unevenly done chicken. In 1939, he found that using a pressure fryer produced tasty, moist chicken in eight or nine minutes. By July 1940, Sanders finalized what came to be known as his Original Recipe.

After Sanders formed a partnership with Pete Harman, they began marketing the chicken in the 1950s as Kentucky Fried Chicken; the company shipped the spices already mixed to restaurants to preserve the recipe's secrecy. He claimed that the ingredients "stand on everybody's shelf".

Sanders used vegetable oil for frying chicken. By 1993, for economic reasons, many KFC outlets had chosen to use a blend of palm and soybean oil. In Japan, the oil used is mainly the more expensive cottonseed and corn oil, as KFC Japan believes that this offers superior taste quality.

๐Ÿ”— My Trial as a War Criminal (By Leo Szilard, Inventor of Nuclear Chain Reaction)

๐Ÿ”— Military history ๐Ÿ”— Military history/Military biography

"My Trial as a War Criminal" is a 1949 short story by atomic physicist Leo Szilard. Szilard had played a leading role in the Manhattan Project, and in the story he imagines the kind of show trial he might have had if he had been prosecuted in a manner similar to the Nuremberg Trials. Szilard earlier drafted the letter Albert Einstein signed, to Franklin Roosevelt, suggesting the US develop the military uses of nuclear power, and later the petition unsuccessfully advocating against the use of nuclear weapons.

๐Ÿ”— Acrostic

๐Ÿ”— Poetry ๐Ÿ”— Bible

An acrostic is a poem (or other form of writing) in which the first letter (or syllable, or word) of each line (or paragraph, or other recurring feature in the text) spells out a word, message or the alphabet. The word comes from the French acrostiche from post-classical Latin acrostichis, from Koine Greek แผ€ฮบฯฮฟฯƒฯ„ฮนฯ‡ฮฏฯ‚, from Ancient Greek แผ„ฮบฯฮฟฯ‚ "highest, topmost" and ฯƒฯ„ฮฏฯ‡ฮฟฯ‚ "verse". As a form of constrained writing, an acrostic can be used as a mnemonic device to aid memory retrieval.

Relatively simple acrostics may merely spell out the letters of the alphabet in order; such an acrostic may be called an 'alphabetical acrostic' or abecedarius. These acrostics occur in the first four of the five chapters that make up the Book of Lamentations, in the praise of the good wife in Proverbs 31:10-31, and in Psalms 25, 34, 37, 111, 112, 119 and 145 of the Hebrew Bible. Notable among the acrostic Psalms is the long Psalm 119, which typically is printed in subsections named after the 22 letters of the Hebrew alphabet, each section consisting of 8 verses, each of which begins with the same letter of the alphabet and the entire psalm consisting of 22 x 8 = 176 verses; and Psalm 145, which is recited three times a day in the Jewish services. Some acrostic psalms are technically imperfect. E.g. Psalm 9 and Psalm 10 appear to constitute a single acrostic psalm together, but the length assigned to each letter is unequal and five of the 22 letters of the Hebrew alphabet are not represented and the sequence of two letters is reversed. In Psalm 25 one Hebrew letter is not represented, the following letter (Resh) repeated. In Psalm 34 the current final verse, 23, does fit verse 22 in content, but adds an additional line to the poem. In Psalms 37 and 111 the numbering of verses and the division into lines are interfering with each other; as a result in Psalm 37, for the letters Daleth and Kaph there is only one verse, and the letter Ayin is not represented. Psalm 111 and 112 have 22 lines, but 10 verses. Psalm 145 does not represent the letter Nun, having 21 one verses, but one Qumran manuscript of this Psalm does have that missing line, which agrees with the Septuagint.

Acrostics are common in medieval literature, where they usually serve to highlight the name of the poet or his patron, or to make a prayer to a saint. They are most frequent in verse works but can also appear in prose. The Middle High German poet Rudolf von Ems for example opens all his great works with an acrostic of his name, and his world chronicle marks the beginning of each age with an acrostic of the key figure (Moses, David, etc.). In chronicles, acrostics are common in German and English but rare in other languages.

Often the ease of detectability of an acrostic can depend on the intention of its creator. In some cases an author may desire an acrostic to have a better chance of being perceived by an observant reader, such as the acrostic contained in the Hypnerotomachia Poliphili (where the key capital letters are decorated with ornate embellishments). However, acrostics may also be used as a form of steganography, where the author seeks to conceal the message rather than proclaim it. This might be achieved by making the key letters uniform in appearance with the surrounding text, or by aligning the words in such a way that the relationship between the key letters is less obvious. This is referred to as null ciphers in steganography, using the first letter of each word to form a hidden message in an otherwise innocuous text. Using letters to hide a message, as in acrostic ciphers, was popular during the Renaissance, and could employ various methods of enciphering, such as selecting other letters than initials based on a repeating pattern (equidistant letter sequences), or even concealing the message by starting at the end of the text and working backwards.

๐Ÿ”— Irony punctuation

๐Ÿ”— Typography

Irony punctuation is any proposed form of notation used to denote irony or sarcasm in text. Written English lacks a standard way to mark irony, and several forms of punctuation have been proposed. Among the oldest and most frequently attested is the percontation point proposed by English printer Henry Denham in the 1580s, and the irony mark, used by Marcellin Jobard and French poet Alcanter de Brahm during the 19th century. Both marks take the form of a reversed question mark, "โธฎ".

Irony punctuation is primarily used to indicate that a sentence should be understood at a second level. A bracketed exclamation point or question mark as well as scare quotes are also occasionally used to express irony or sarcasm.

๐Ÿ”— QSL Card

๐Ÿ”— Amateur radio

A QSL card is a written confirmation of either a two-way radiocommunication between two amateur radio or citizens band stations; a one-way reception of a signal from an AM radio, FM radio, television or shortwave broadcasting station; or the reception of a two-way radiocommunication by a third party listener. A typical QSL card is the same size and made from the same material as a typical postcard, and most are sent through the mail as such.

QSL card derived its name from the Q code "QSL". A Q code message can stand for a statement or a question (when the code is followed by a question mark). In this case, 'QSL?' (note the question mark) means "Do you confirm receipt of my transmission?" while 'QSL' (without a question mark) means "I confirm receipt of your transmission."

๐Ÿ”— Loglan โ€“ a predicate logic-based language for humans

๐Ÿ”— Constructed languages

Loglan is a constructed language originally designed for linguistic research, particularly for investigating the Sapirโ€“Whorf Hypothesis. The language was developed beginning in 1955 by Dr James Cooke Brown with the goal of making a language so different from natural languages that people learning it would think in a different way if the hypothesis were true. In 1960 Scientific American published an article introducing the language. Loglan is the first among, and the main inspiration for, the languages known as logical languages, which also includes Lojban.

Brown founded The Loglan Institute (TLI) to develop the language and other applications of it. He always considered the language an incomplete research project, and although he released many papers about its design, he continued to claim legal restrictions on its use. Because of this, a group of his followers later formed the Logical Language Group to create the language Lojban along the same principles, but with the intention to make it freely available and encourage its use as a real language.

Supporters of Lojban use the term Loglan as a generic term to refer to both their own language, and Brown's Loglan, referred to as "TLI Loglan" when in need of disambiguation. Although the non-trademarkability of the term Loglan was eventually upheld by the United States Patent and Trademark Office, many supporters and members of The Loglan Institute find this usage offensive, and reserve Loglan for the TLI version of the language.

๐Ÿ”— Technology ๐Ÿ”— Physics ๐Ÿ”— Neuroscience ๐Ÿ”— Molecular Biology ๐Ÿ”— Molecular Biology/Molecular and Cell Biology

Confocal microscopy, most frequently confocal laser scanning microscopy (CLSM) or laser scanning confocal microscopy (LSCM), is an optical imaging technique for increasing optical resolution and contrast of a micrograph by means of using a spatial pinhole to block out-of-focus light in image formation. Capturing multiple two-dimensional images at different depths in a sample enables the reconstruction of three-dimensional structures (a process known as optical sectioning) within an object. This technique is used extensively in the scientific and industrial communities and typical applications are in life sciences, semiconductor inspection and materials science.

Light travels through the sample under a conventional microscope as far into the specimen as it can penetrate, while a confocal microscope only focuses a smaller beam of light at one narrow depth level at a time. The CLSM achieves a controlled and highly limited depth of field.
