Vertigo

Derived from a Latin phrase meaning "a condition of turning about," the term vertigo is used in medical circles to describe the sensation of spinning or swaying while the body is stationary. Usually associated with a disturbance in the inner ear balance mechanism, the brain, or nerve connections between the two, vertigo is a major symptom of a balance disorder. There are two types of vertigo: subjective and objective.

The Deadly Yellow River

Stretching 3,395 miles (5,464 km), the Yellow River, or Huang He, is the world's sixth longest river. Called the "the cradle of Chinese civilization" because its basin is the birthplace of the northern Chinese civilizations, the oft-flooding river has also earned the nickname "China's Sorrow." Its floods—more than 1,500 in the last 3 to 4 millennia—have caused some of the deadliest natural disasters in human history and claimed millions of lives.

The Motif of Harmful Sensation

The motif of harmful sensation, a recurring concept in both traditional and modern stories, involves the idea that a person can suffer physical or mental harm merely by experiencing an ordinarily benign sensation. This motif is especially apparent in Greek mythology and the tale of Medusa, a being so ugly that all who look at her turn to stone. Although the concept is largely rooted in fiction, it is not entirely fanciful

Petrosomatoglyphs

Petrosomatoglyphs are naturally-occurring or man-made representations of human or animal body parts that are found incised in rock. Footprints are the most common form of petrosomatoglyph. The ancient images, some of which date back to megalithic times, were once considered important symbols and were used in both religious and secular ceremonies.

Rube Goldberg Machine

A Rube Goldberg machine is an exceedingly complex apparatus that performs a very simple task in an incredibly indirect and convoluted way. Named after cartoonist Rube Goldberg, who was known for illustrating such contraptions, the machines are now the subject of an annual national competition at Purdue University, where teams are judged on their machine's ability to complete a certain task using as many steps as possible without a single failure.

Frogmen

An allusion to the appearance of divers clad in shiny wetsuits and wearing large fins on their feet, the term "frogman" was first used to describe scuba divers around 1940. Although scuba users prefer to be called "divers," the word "frogman" is often used, especially by the media, to refer to professional divers, such as soldiers, who carry out amphibious assaults, sabotage operations, and clandestine surveys

The Ultimate Fate of the Universe

A number of theories have been proposed regarding the ultimate fate of the universe. Some, like the Big Crunch and the Big Rip, suggest the universe will come to an end, while others conclude that it will exist for an infinite period of time. Most cosmologists agree that the universe's average density, the rate at which it expands, and the physical properties of the mass and energy in the universe will determine its ultimate fate

Islamic Banking

Islamic banking is a system of banking that is consistent with Islamic Sharia law. In particular, it prohibits usury—the collection and payment of interest—and investment in businesses considered unlawful. In the late 20th century, a number of Islamic banks were created to cater to the needs of the Muslim banking market. These institutions rely on the common Islamic concepts of profit sharing, safekeeping, joint venture, and leasing.

Chelation Therapy

Chelation therapy is the intravenous administration of chelating agents to remove heavy metals from the body. Chelating agents work by making chemical bonds with metal ions, resulting in a water-soluble complex that can enter the bloodstream and be harmlessly excreted. Introduced during World War I to treat soldiers exposed to poison gases, chelation therapy is now used to treat acute toxic metal poisoning.

Sir Thomas Phillipps and His Multitude of Books

An English antiquary and book collector, Phillipps amassed the largest collection of manuscript material in the 19th century. He suffered from severe bibliomania—an obsessive-compulsive disorder involving the collecting or hoarding of books—and spent much of his inherited fortune expanding his holdings, which ultimately contained some 100,000 books and manuscripts and was arguably the largest collection amassed by a single individual.

The Black Obelisk

The most complete Assyrian obelisk yet discovered, the Black Obelisk of Shalmaneser III is a black limestone Neo-Assyrian bas-relief sculpture. Found in 1846 in what is now northern Iraq, the sculpture was originally erected as a public monument in 825 BCE, at a time of civil war. It features 20 reliefs depicting 5 kings bringing tribute and prostrating before the Assyrian king

Brocken Specter

A Brocken specter is an optical phenomenon sometimes seen at high altitudes, when the observer is between the sun and a mass of clouds. The figures of the observer and surrounding objects are seen projected on the clouds, greatly enlarged and often encircled by a colorful halo. The phenomenon, named after a peak in Germany's Harz Mountains where it is often observed, can be seen on misty mountainsides, in cloud banks, and even from airplanes

The Pilates Method

Often simply called Pilates, the Pilates Method is a physical fitness system developed in the early 20th century by Joseph Pilates, who believed that mental and physical health are essential to one another. Pilates developed the method during WWI to help hospitalized veterans condition their bodies by strengthening, stretching, and stabilizing key muscles. The program focuses on the core postural muscles, spinal alignment, and breathing technique.

Waffles

Waffles are light batter cakes cooked between two gridded hot plates that give the food its distinctive, pocketed pattern. The modern waffle has its origins in the wafers—thin, crisp cakes made from a mixture of barley and oats and baked between wafer-irons—that were popular in the Middle Ages. Today, a number of waffle varieties are enjoyed throughout the world, including Belgian, Liège, American, and Hong Kong-style waffles.

Atenism

One of the earliest monotheistic religions, Atenism was introduced during the 14th century BCE by Pharaoh Amenhotep IV, later known by his adopted name, Akhenaten. After raising the obscure sun god known as Aten to the status of supreme god, Akhenaten declared the solar deity the only god and forbade the worship of all others. Atenism remained Egypt's state religion for approximately 20 years before falling out of favor.

Passenger fixes faulty airliner
Holidaymakers avoided a long delay to their flight home when a passenger fixed a mechanical problem with their plane.
Passengers on Thomas Cook flight TCX9641 from Menorca were told to expect an eight-hour wait while an engineer was flown out from the UK.
One passenger then identified himself as a qualified aircraft engineer and offered to try to remedy the fault.
He was successful, and the plane landed in Glasgow only 35 minutes late.

Transits of Venus

When Venus passes directly between Earth and the Sun, it appears to observers as though a small disk is moving across the face of the Sun. Before the space age, such transits helped scientists calculate the distance between Earth and the Sun. Among the rarest of predictable astronomical phenomena, transits of Venus currently occur in a pattern that repeats every 243 years, with pairs of transits 8 years apart separated by gaps of 121.5 and 105.5 years.

The Habiru

Sumerian, Egyptian, Akkadian, Hittite, Mitanni, and Ugaritic sources recorded roughly 3,200 to 4,000 years ago mention the Habiru, a group of people found throughout the Fertile Crescent, which spanned the Levant, Mesopotamia, and ancient Egypt. Depending on the source and epoch, the Habiru are variously described as nomads, rebels, outlaws, mercenaries, bowmen, slaves, or migrant laborers
