"We must overcome the urge to do things in unison.To chant together, to hum banal tunes together, is not collectivity. A carnival is not a revolution.After the carnival, after the removal of the masks, you are precisely who you were before. After the tragedy, you are not certain who you are. Ideology is the outcome of pain.Some people want to know pain. There is no truth on the cheap.There are more people in pursuit of knowledge than the accountants will admit.There is always the possibility of an avalanche of truth-seekers.Art is a problem. The man or woman who exposes himself to art exposes himself to another problem.It is an error typical of the accountant to think there is no audience for the problem.Some people want to grow in their souls.But not all people. Consequently, tragedy is elitist."

"The continental shelf is a relatively shallow, near horizontal submarine terrace of continental crust forming the edge of a continental landmass. This shelf typically extends from the coast to depths of 100–200 meters, and ends at its seaward edge with an abrupt drop called the shelf break. Continental shelves have an average width of 70 km and make up about 8 percent of the entire area covered by oceans."

In the past decade, South Korea, China and the United States have started research programs to foster circular economies by boosting remanufacturing and reuse. Europe is taking baby steps. The Swedish Foundation for Strategic Environmental Research (Mistra) and the EU Horizon 2020 program published their first call for circular-economy proposals in 2014. The European Commission submitted a Circular Economy Package to the European Parliament last December. Since 2010, the Ellen MacArthur Foundation, founded by the round-the-world yachtswoman, has been boosting awareness of the idea in manufacturers and policymakers. And circular-economy concepts have been successfully applied on small scales since the 1990s in eco-industrial parks such as the Kalundborg Symbiosis in Denmark, and in companies that include Xerox (selling modular goods as services), Caterpillar (remanufacturing used diesel engines) and USM Modular Furniture. Selling services rather than goods is familiar in hotels and in public transport; it needs to become mainstream in the consumer realm.

"The first public act of Ramses after his accession to sole rule was to visit Thebes, the southern capital, for the great religious festival of Opet, when the god Amon of Karnak made a state visit in his ceremonial barge to the Temple of Luxor. When returning to his home in the north, the king broke his journey at Abydos to worship Osiris and to arrange for the resumption of work on the great temple founded there by his father, which had been interrupted by the old king’s death. He also took the opportunity to appoint as the new high priest of Amon at Thebes a man named Nebwenenef, high priest of Anhur at nearby This (Thinis)."

"In mathematics, Zermelo–Fraenkel set theory, named after mathematicians Ernst Zermelo and Abraham Fraenkel, is an axiomatic system that was proposed in the early twentieth century in order to formulate a theory of sets free of paradoxes such as Russell's paradox. The axiom of choice is independent of other axioms of ZF set theory. Zermelo–Fraenkel set theory with the historically controversial axiom of choice included is abbreviated ZFC, where C stands for "choice"[1] ZF refers to the axioms of Zermelo–Fraenkel set theory with the axiom of choice excluded. Today ZFC is the standard form of axiomatic set theory and as such is the most common foundation of mathematics."

"Hepatic fibrosis is the final common pathway for most chronic liver diseases. The cell responsible for hepatic fibrosis appears to be the activated myofibroblast. The myofibroblast may be derived from quiescent hepatic stellate cells, epithelial to mesenchymal transition, or derived from bone marrow precursors. Hepatic fibrosis is strongly associated with oxidative stress, increased transforming growth factor beta, hepatocyte death, and chronic inflammation. Finally, the reversal of fibrosis depends upon the elimination of the activated myofibroblast"

"Depression is not a normal part of growing older, and it should never be taken lightly. Unfortunately, depression often goes undiagnosed and untreated in older adults, and they may feel reluctant to seek help. Symptoms of depression may be different or less obvious in older adults, such as: memory difficulties or personality changes Physical aches or pain, fatigue, loss of appetite, sleep problems or loss of interest in sex — not caused by a medical condition or medication, often wanting to stay at home, rather than going out to socialize or doing new things and suicidal thinking or feelings"

"First of all, we need to give up the idea that the world is organised in a rational way. The world has not gone mad. It has in fact always been mad. The German philosopher Arthur Schopenhauer argued that at the heart of everything – and that includes us – is not reason but blind will. This, he wrote, explains why the world is in such a sorry state and we keep messing things up by fighting needless wars and inflicting so much suffering on ourselves and each other."

"The Andromeda Galaxy, spanning approximately 220,000 light years. Based on its appearance in visible light, the Andromeda Galaxy is classified as an SA-b galaxy in the classification system of spiral galaxies. A spiral galaxy like the Milky Way, Andromeda contains a concentrated bulge of matter in the middle, surrounded by a disk of gas, dust, and stars and an immense halo. Though Andromeda contains approximately a trillion stars to the quarter to half a billion in the Milky Way, our galaxy is actually more massive, because it is thought to contain more dark matter."

"The Starry Night is an oil on canvas by the Dutch post-impressionist painter Vincent van Gogh. Painted in June 1889, it depicts the view from the east-facing window of his asylum room at Saint-Rémy-de-Provence, just before sunrise, with the addition of an idealized village. It has been in the permanent collection of the Museum of Modern Art in New York City since 1941, acquired through the Lillie P. Bliss Bequest. Regarded as among Van Gogh's finest works, The Starry Night is one of the most recognized paintings in the history of Western culture."

"One of the earliest examples of a scientific approach to physical and mathematical problems applicable to civil engineering is the work of Archimedes in the 3rd century BC, including Archimedes Principle, which underpins our understanding of buoyancy, and practical solutions such as Archimedes' screw."

"The Age of the Enlightenment witnessed considerable development in architectural theory on the European continent. New archeological discoveries (such as those of Pompeii and Herculaneum) drove new interest in Classical art and architecture."
