The Spanish shawl (Flabellina iodinea) is a nudibranch native to the North American west coast, ranging from British Columbia, Canada to Baja California Sur, Mexico, and even the Galápagos Islands. Nudibranchs are carnivorous sea slugs. They are among the most colorful creatures on earth. Their color patterns make them invisible or warn off predators as being distasteful or poisonous.

Hypervelocity is a very high velocity (over 3,000 m/s [10,000 ft/s]), such that the strength of materials is very small compared to inertial stresses. This is especially important in the case of space debris, which can be highly damaging to functioning satellites when impacting at orbital speeds. Shown here is the "energy flash" of a hypervelocity impact during a simulation of what happens when a piece of orbital debris hits a spacecraft in orbit. Photo credit: NASA/Vanderdecken |

Caslon is the name of a large family of serif typefaces designed by William Caslon. It is cited as the first original typeface of English origin—English printers prior to this time used mainly imported Dutch types. The United States Declaration of Independence was printed in Caslon. Although its popularity has waned, it is still used for book typography, and a favorite saying of printers remains, "When in doubt, use Caslon." This specimen was designed and printed by William Caslon, and includes a variety of fonts for several languages. Image credit: William Caslon |

A warship is a ship that is built and primarily intended for war. They are designed to withstand damage and are usually both faster and more manoeuvrable than merchant ships. A warship typically only carries weapons, ammunition and supplies for its own crew. Warships usually belong to a navy, though they have sometimes been operated by individuals or companies. This plate from the 1728 Cyclopaedia shows first and third rate English warships. Illustration credit: 1728 Cyclopaedia |

The Great Wall of China is a 6,352 km (3,948 miles) long Chinese fortification built over a span of nearly 2,000 years, in order to protect the various dynasties from raids coming from areas in modern-day Mongolia and Manchuria. Along most of its arc, it roughly delineates the border between North China and Inner Mongolia. Although it is commonly said that the wall is visible to the naked eye from space, it is more accurate to say that it is visible under favorable viewing conditions, if one knows exactly where to look.

The Woolworth Building in New York City is considered to be the world's first skyscraper. It was constructed in 1913 and was the world's tallest building for seventeen years and today remains one of the fifty tallest buildings in the United States. The building was owned by the F.W. Woolworth Company for 85 years until it was sold in 1998. Most of the ornate lobby, previously a tourist attraction, was restricted to those with business in the building after the September 11, 2001 attacks. Photo credit: Pictorial News Co. |

The Lockheed SR-71, commonly known as the "Blackbird", was an advanced, long-range, Mach 3 strategic reconnaissance aircraft that flew from 1964–98. The SR-71 was one of the first aircraft to be shaped to have an extremely low radar signature. The aircraft flew so fast and so high that if the pilot detected a surface-to-air missile launch, the standard evasive action was simply to accelerate. During its entire operational life, more than 3,000 missiles were fired at the aircraft, yet no SR-71 was ever shot down. Photo credit: NASA |

A pirate is a person who commits piracy by engaging in robbery, pillaging, or plundering at sea. The earliest known pirates are the Sea Peoples (13th century BC), but the classic era of piracy in the Caribbean lasted from about 1560 until the 1720s. Seaborne piracy against transport vessels remains a significant issue, particularly in the waters between the Pacific and Indian oceans. In popular culture, pirates are associated with a stereotypical manner of speaking and dress, as shown in this caricature. This tradition owes much to Robert Newton's portrayal of Long John Silver in the 1950 film Treasure Island. Illustration credit: J.J./Gustavb |

Hummingbirds are small birds in the family Trochilidae. They are known for their ability to hover in mid-air by rapidly flapping their wings, 15 to 80 times per second (depending on the size of the bird). Unlike other bird species capable of limited hovering, the hummingbird is alone in its ability to fly deliberately backwards or vertically, and to maintain position for drinking from flower blossoms. They are named for the characteristic hum made by their wings. Hummingbirds are found only in the Americas, from southern Canada and Alaska to Tierra del Fuego, including the West Indies. The majority of species occur in tropical Central and South America, but several species also breed in temperate areas. Illustration credit: Ernst Haeckel |

Chickens (a one-day-old chick pictured) are domesticated birds often raised as a type of poultry. With a population of more than 24 billion in 2003, there are more chickens in the world than any other bird. They serve as one of the most common meats around the globe, and are frequently prepared as food in a large number of ways. In some areas, notably Asia, they are also kept as pets.

The "Maid of Orleans", Joan of Arc is a national heroine of France and a saint of the Roman Catholic Church. She helped inspire Charles VII's troops to retake most of his dynasty's former territories, which had been under English and Burgundian dominance during the Hundred Years' War. She later was convicted of heresy (overturned posthumously) and burnt at the stake at the age of nineteen. Pope Benedict XV canonized her on 16 May 1920 and she is now one of the most popular saints of the Catholic Church. Shown here is a statue of Joan of Arc inside Notre Dame de Paris, a Gothic cathedral in Paris, where she was beatified in 1909. Photo credit: Steven G. Johnson |

Alchemy refers to both an early protoscientific and an early philosophical discipline, both combining elements of chemistry, metallurgy, physics, medicine, astrology, semiotics, mysticism, spiritualism, and art. Alchemy has been practiced in Mesopotamia, Ancient Egypt, Persia, India, and China, in Classical Greece and Rome, in the Islamic empire, and then in Europe up to the nineteenth century — in a complex network of schools and philosophical systems spanning at least 2500 years.

An image of an ant drinking nectar from the peristome of an upper pitcher of a Nepenthes rafflesiana, a species of carnivorous pitcher plant found in Borneo, Sumatra, Peninsular Malaysia and Singapore. It produces two distinct types of pitchers, which are used to capture and kill insect prey for nutrients. The lower pitchers are generally round, squat and 'winged', while the upper pitchers are more narrow at their base. N. rafflesiana is very popular in cultivation and is commonly recommended as a "first plant" to new Nepenthes growers. Most N. rafflesiana plants on the market today are propagated by tissue culture or other forms of vegetative propagation. Photo credit: NepGrower |

The 67th plate from Ernst Haeckel's Kunstformen der Natur (1904), depicting an assortment of Bats (Chiroptera). They are the only mammals capable of flight, thanks to their forelimbs which are developed as wings. There are about 1,100 species of bats worldwide, which is about 20% of all mammal species. About 70 percent of bats are insectivorous. Most of the remainder feed on fruits and their juices, but some prey on vertebrates. Illustration credit: Ernst Haeckel |

Miners pose with lunch pails in hand on a pile of "poor rock" (waste rock), which had been broken off the richer copper-bearing rock in the Tamarack #5 Shaft-Rockhouse (seen in the background) at the Tamarack Mine, located in Copper Country, Michigan, USA. This picture (from 1905) was most likely taken during the shift-change, just as miners were going down into, or had just come up from the mines. Photo credit: Adolph F. Isler |

The Kayan or Padaung are a group of the Karen people found in Myanmar and Thailand. They are known for a particular body modification, which consists of coiling lengths of brass around the neck of the women. The coils are first applied when the girls are about five years old, and the coil is replaced with longer coils as the weight of the brass pushes down the collar bone and compresses the rib cage, resulting in the appearance of a very long neck. The practice has seen a surge in recent years because the custom draws tourists who buy their handicrafts. Photo credit: Diliff |
