🔗 Ken Allen

🔗 Zoo 🔗 Primates

Ken Allen (February 13, 1971 – December 1, 2000) was a Bornean orangutan at the San Diego Zoo. He became one of the most popular animals in the history of the zoo because of his many successful escapes from his enclosures. He was nicknamed "the hairy Houdini".

Ken Allen was born in captivity at the San Diego Zoo in 1971. During the 1980s, Ken Allen gained worldwide attention for a series of three escapes from his enclosure, which had been thought to be escape-proof. During some of his escapes, his female companions would join him. Ken Allen's ability to outwit his keepers, as well as his docile demeanor during his escapes, resulted in fame. He had his own fan club, and was the subject of T-shirts and bumper stickers (most reading "Free Ken Allen"). A song, The Ballad of Ken Allen, was written about him.

Ken Allen developed prostate cancer and was euthanized on December 1, 2000. He was 29 years old.

🔗 Ukraine and Weapons of Mass Destruction

🔗 Military history 🔗 Military history/Military science, technology, and theory 🔗 Military history/Weaponry 🔗 History of Science 🔗 Ukraine 🔗 Military history/European military history

Ukraine, formerly a republic of the Union of Soviet Socialist Republics (USSR) from 1922 to 1991, once hosted Soviet nuclear weapons and delivery systems on its territory. The former Soviet Union had its nuclear program expanded to only four of its republics: Belarus, Kazakhstan, Russia, and Ukraine. After its dissolution in 1991, Ukraine inherited about 130 UR-100N intercontinental ballistic missiles (ICBM) with six warheads each, 46 RT-23 Molodets ICBMs with ten warheads apiece, as well as 33 heavy bombers, totaling approximately 1,700 nuclear warheads that remained on Ukrainian territory. Thus Ukraine became the third largest nuclear power in the world (possessing 300 more nuclear warheads than Kazakhstan, 6.5 times less than the United States, and ten times less than Russia) and held about one third of the former Soviet nuclear weapons, delivery system, and significant knowledge of its design and production. While all these weapons were located on Ukrainian territory, initially they were not under Ukraine's control.

In July 1993, the Ukrainian parliament proclaimed ownership of the former Soviet nuclear weapons deployed on its territory. Testimony from the same year by Bruce G. Blair cited the Russian Ministry of Defence’s Chief Directorate for Nuclear Munitions, Colonel General Yevgeniy Maslin, who reportedly stated that Russia had de facto lost control over the nuclear weapons stationed in Ukraine. The same report noted that crews operating strategic nuclear bombers, along with subunits responsible for nuclear munitions, had been incorporated into the Ukrainian Armed Forces, while Moscow still retained operational control over the strategic missile forces at that time. By late 1993, some estimates suggested that Ukraine could break the nuclear release codes between December 1993 and March 1994, as there were no fundamental obstacles preventing it from doing so.

In 1994, Ukraine agreed to transfer these weapons to Russia for dismantlement and became a party to the Treaty on the Non-Proliferation of Nuclear Weapons, in exchange for economic compensation and assurances from Russia, the United States and the United Kingdom to respect Ukrainian independence and sovereignty within its existing borders. Almost twenty years later, Russia, one of the parties to the agreement, invaded Ukraine in 2014 and subsequently also from 2022 onwards.

🔗 Cell (microprocessor)

🔗 Computing 🔗 Computer science 🔗 Brands

Cell is a multi-core microprocessor microarchitecture that combines a general-purpose PowerPC core of modest performance with streamlined coprocessing elements which greatly accelerate multimedia and vector processing applications, as well as many other forms of dedicated computation.

It was developed by Sony, Toshiba, and IBM, an alliance known as "STI". The architectural design and first implementation were carried out at the STI Design Center in Austin, Texas over a four-year period beginning March 2001 on a budget reported by Sony as approaching US$400 million. Cell is shorthand for Cell Broadband Engine Architecture, commonly abbreviated CBEA in full or Cell BE in part.

The first major commercial application of Cell was in Sony's PlayStation 3 game console, released in 2006. In May 2008, the Cell-based IBM Roadrunner supercomputer became the first TOP500 LINPACK sustained 1.0 petaflops system. Mercury Computer Systems also developed designs based on the Cell.

The Cell architecture includes a memory coherence architecture that emphasizes power efficiency, prioritizes bandwidth over low latency, and favors peak computational throughput over simplicity of program code. For these reasons, Cell is widely regarded as a challenging environment for software development. IBM provides a Linux-based development platform to help developers program for Cell chips.

🔗 Seam Carving

🔗 Computing

Seam carving (or liquid rescaling) is an algorithm for content-aware image resizing, developed by Shai Avidan, of Mitsubishi Electric Research Laboratories (MERL), and Ariel Shamir, of the Interdisciplinary Center and MERL. It functions by establishing a number of seams (paths of least importance) in an image and automatically removes seams to reduce image size or inserts seams to extend it. Seam carving also allows manually defining areas in which pixels may not be modified, and features the ability to remove whole objects from photographs.

The purpose of the algorithm is image retargeting, which is the problem of displaying images without distortion on media of various sizes (cell phones, projection screens) using document standards, like HTML, that already support dynamic changes in page layout and text but not images.

Image Retargeting was invented by Vidya Setlur, Saeko Takage, Ramesh Raskar, Michael Gleicher and Bruce Gooch in 2005. The work by Setlur et al. won the 10-year impact award in 2015.

🔗 Ortega hypothesis

🔗 Science

The Ortega hypothesis holds that average or mediocre scientists contribute substantially to the advancement of science. According to this hypothesis, scientific progress occurs mainly by the accumulation of a mass of modest, narrowly specialized intellectual contributions. On this view, major breakthroughs draw heavily upon a large body of minor and little-known work, without which the major advances could not happen.

🔗 Gödel's ontological proof

🔗 Philosophy 🔗 Philosophy/Logic 🔗 Philosophy/Contemporary philosophy 🔗 Philosophy/Philosophy of religion 🔗 Christianity 🔗 Christianity/theology 🔗 Military history/European military history

Gödel's ontological proof is a formal argument by the mathematician Kurt Gödel (1906–1978) for the existence of God. The argument is in a line of development that goes back to Anselm of Canterbury (1033–1109). St. Anselm's ontological argument, in its most succinct form, is as follows: "God, by definition, is that for which no greater can be conceived. God exists in the understanding. If God exists in the understanding, we could imagine Him to be greater by existing in reality. Therefore, God must exist." A more elaborate version was given by Gottfried Leibniz (1646–1716); this is the version that Gödel studied and attempted to clarify with his ontological argument.

Gödel left a fourteen-point outline of his philosophical beliefs in his papers. Points relevant to the ontological proof include

4. There are other worlds and rational beings of a different and higher kind.
5. The world in which we live is not the only one in which we shall live or have lived.
13. There is a scientific (exact) philosophy and theology, which deals with concepts of the highest abstractness; and this is also most highly fruitful for science.
14. Religions are, for the most part, bad—but religion is not.
