A Fire Upon the Deep is a 1992 science fiction novel by American writer Vernor Vinge. It is a space opera involving superhuman intelligences, aliens, variable physics, space battles, love, betrayal, genocide, and a communication medium resembling Usenet. A Fire Upon the Deep won the Hugo Award in 1993, sharing it with Doomsday Book by Connie Willis.

Besides the normal print book editions, the novel was also included on a CD-ROM sold by ClariNet Communications along with the other nominees for the 1993 Hugo awards. The CD-ROM edition included numerous annotations by Vinge on his thoughts and intentions about different parts of the book, and was later released as a standalone e-book (no longer available).

The Airbus A300-600ST (Super Transporter), or Beluga, is a version of the standard A300-600 wide-body airliner modified to carry aircraft parts and outsize cargo. It received the official name of Super Transporter early on; however, the name Beluga, a whale it resembles, gained popularity and has since been officially adopted. The Beluga XL, based on the Airbus A330 with similar modifications and dimensions, was developed by Airbus to replace the type in January 2020.

🔗 Food and drink 🔗 Chemistry

Alcohol powder or powdered alcohol or dry alcohol is a product generally made using micro-encapsulation. When reconstituted with water, alcohol (specifically ethanol) in powder form becomes an alcoholic drink. In March 2015 four product labels for specific powdered alcohol products were approved by the United States Alcohol and Tobacco Tax and Trade Bureau (TTB) which opened the doors for legal product sales. However, as of 4 January 2016, the product is not yet available for sale and legalization remains controversial due to public-health and other concerns. Researchers have expressed concern that, should the product go into production, increases in alcohol misuse, abuse, and associated physical harm to its consumers could occur above what has been historically associated with liquid alcohol alone.

The Kyshtym disaster, sometimes referred to as the Mayak disaster or Ozyorsk disaster in newer sources, was a radioactive contamination accident that occurred on 29 September 1957 at Mayak, a plutonium production site for nuclear weapons and nuclear fuel reprocessing plant located in the closed city of Chelyabinsk-40 (now Ozyorsk) in Chelyabinsk Oblast, Russian SFSR, Soviet Union.

The disaster was the second worst nuclear incident (by radioactivity released) after the Chernobyl disaster. It measured as a Level 6 disaster on the International Nuclear Event Scale (INES), making it the third highest on the INES (which ranks by population impact), behind Chernobyl (evacuated 335,000 people) and the Fukushima Daiichi nuclear disaster (evacuated 154,000 people) which are both Level 7 on the INES. At least twenty-two villages were exposed to radiation from the Kyshtym disaster, with a total population of around 10,000 people evacuated. Some were evacuated after a week, but it took almost two years for evacuations to occur at other sites.

The disaster spread hot particles over more than 52,000 square kilometres (20,000 sq mi), where at least 270,000 people lived. Since Chelyabinsk-40 (later renamed Chelyabinsk-65 until 1994) was not marked on maps, the disaster was named after Kyshtym, the nearest known town.

The Christian holiday Easter has several names. The names differ depending on languages, but most are derived from Greek and Latin "pascha", which is taken from the Hebrew פֶּסַח (Pesach), meaning Passover. The modern English term Easter developed from the Old English word Ēastre or Ēostre (Old English pronunciation: [ˈæːɑstre, ˈeːostre]), which itself developed prior to 899, originally referring to the name of the Anglo-Saxon goddess Ēostre.

Al pastor (from Spanish, "shepherd style"), tacos al pastor, or tacos de trompo is a preparation of spit-grilled slices of pork originating in the Central Mexican region of Puebla and Mexico City, although today it is a common menu item found in taquerías throughout Mexico. The method of preparing and cooking al pastor is based on the lamb shawarma brought by Lebanese immigrants to the region. Al pastor features a flavor palate that uses traditional Mexican adobada (marinade). It is a popular street food that has spread to the United States. In some places of northern Mexico and coastal Mexico, such as in Baja California, taco al pastor is known as taco de trompo or taco de adobada. A similar dish also from Puebla that uses a combination of middle eastern spices and indigenous central Mexican ingredients is called tacos árabes.

🔗 Philosophy 🔗 Philosophy/Contemporary philosophy 🔗 Philosophy/Ethics

Master–slave morality (German: Herren- und Sklavenmoral) is a central theme of Friedrich Nietzsche's works, particularly in the first essay of his book, On the Genealogy of Morality. Nietzsche argued that there were two fundamental types of morality: "master morality" and "slave morality". Master morality values pride and power, while slave morality values kindness, empathy, and sympathy. Master morality judges actions as good or bad (e.g. the classical virtues of the noble man versus the vices of the rabble), unlike slave morality, which judges by a scale of good or evil intentions (e. g. Christian virtues and vices, Kantian deontology).

For Nietzsche, a morality is inseparable from the culture which values it, meaning that each culture's language, codes, practices, narratives, and institutions are informed by the struggle between these two moral structures.
