Xeroradiography - is a type of X-ray imaging in which a picture of the body is recorded on paper rather than on film. In this technique, a plate of selenium, which rests on a thin layer of aluminium oxide, is charged uniformly by passing it in front of a scorotron. As X-ray photon impinges on this amorphous coat of selenium, charges diffuse out, in proportion to energy content of the X-ray. This occurs as a result of photoconduction. The resulting imprint, in the form of charge distribution on the plate, attracts toner particles, which is then transferred to reusable paper plates. In contrast to conventional X-rays, photographic developers are not needed. Hence the term xeroradiography; 'xero' meaning dry in Greek. It requires more radiation exposure. Historically used in mammography prior to the advent of digital mammography. The process was developed by engineer Dr. Robert C. McMaster in 1950.

Remember Y2K, now we can look forward to this.............

Year 2038 Problem ((also called Y2038 or Y2k38 or Unix Y2K) relates to representing time in many digital systems as the number of seconds passed since 00:00:00 UTC on 1 January 1970 and storing it as a signed 32-bit integer. Such implementations cannot encode times after 03:14:07 UTC on 19 January 2038. Similar to the Y2K problem, the Year 2038 problem is caused by insufficient capacity used to represent time)

Zodiac - is an area of the sky that extends approximately 8° north or south (as measured in celestial latitude) of the ecliptic, the apparent path of the Sun across the celestial sphere over the course of the year. The paths of the Moon and visible planets are also within the belt of the zodiac.

The Earth in its orbit around the Sun causes the Sun to appear on the celestial sphere moving along the ecliptic (red), which is tilted 23.44° with respect to the celestial equator (blue-white).

In Western astrology, and formerly astronomy, the zodiac is divided into twelve signs, each occupying 30° of celestial longitude and roughly corresponding to the constellations: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces.

Artificial Intelligence (sometimes called machine intelligence, is intelligence demonstrated by machines, unlike the natural intelligence displayed by humans and animals. Leading AI textbooks define the field as the study of "intelligent agents": any device that perceives its environment and takes actions that maximize its chance of successfully achieving its goals. Colloquially, the term "artificial intelligence" is often used to describe machines (or computers) that mimic "cognitive" functions that humans associate with the human mind, such as "learning" and "problem solving")

The Battle of New Orleans - was fought on January 8, 1815 between the British Army under Major General Sir Edward Pakenham and the United States Army under Brevet Major General Andrew Jackson, roughly 5 miles southeast of New Orleans, close to Chalmette, Louisiana. The battle took place 18 days after the signing of the Treaty of Ghent, which formally ended the War of 1812 on December 24, 1814, as news of the agreement had not yet reached the United States from Europe. Despite a large British advantage in numbers, training, and experience, the American forces defeated a poorly executed assault in slightly more than 30 minutes. The Americans suffered roughly 60 casualties, while the British suffered roughly 2,000.

Codex Atlanticus (is a twelve-volume, bound set of drawings and writings by Leonardo da Vinci, the largest such set; its name indicates the large paper used to preserve original Leonardo notebook pages, which was used for atlases. It comprises 1,119 leaves dating from 1478 to 1519, the contents covering a great variety of subjects, from flight to weaponry to musical instruments and from mathematics to botany. This codex was gathered in the late 16th century by the sculptor Pompeo Leoni, who dismembered some of Leonardo's notebooks in its formation. It is currently preserved at the Biblioteca Ambrosiana in Milan)

Death Valley - is a desert valley in Eastern California, in the northern Mojave Desert, bordering the Great Basin Desert. It is one of the hottest places on Earth, along with deserts in the Middle East and the Sahara. Lying mostly in Inyo County, California, near the border of California and Nevada, in the Great Basin, east of the Sierra Nevada mountains, Death Valley constitutes much of Death Valley National Park and is the principal feature of the Mojave and Colorado Deserts Biosphere Reserve. Death Valley's Badwater Basin is the point of lowest elevation in North America, at 282 feet (86 m) below sea level. On the afternoon of July 10, 1913, the United States Weather Bureau recorded a high temperature of 134 °F (56.7 °C) at Furnace Creek in Death Valley, which stands as the highest ambient air temperature ever recorded at the surface of the Earth. This reading, however, and several others taken in that period, a century ago, are in dispute by some modern experts.

Egyptian Hieroglyphics (were the formal writing system used in Ancient Egypt. Hieroglyphs combined logographic, syllabic and alphabetic elements, with a total of some 1,000 distinct characters. Cursive hieroglyphs were used for religious literature on papyrus and wood. The later hieratic and demotic Egyptian scripts were derived from hieroglyphic writing, as was the Proto-Sinaitic script that later evolved into the Phoenician alphabet. Through the Phoenician alphabet's major child systems, the Greek and Aramaic scripts, the Egyptian hieroglyphic script is ancestral to the majority of scripts in modern use, most prominently the Latin and Cyrillic scripts and the Arabic script and Brahmic family of scripts)

The Farne Islands are a group of islands off the coast of Northumberland, England. There are between 15 and 20 islands depending on the state of the tide. They are scattered about 1 ¹⁄2 to 4 ³⁄4 miles from the mainland, divided into two groups, the Inner Group and the Outer Group.

Grace (is a photograph by Eric Enstrom. It depicts an elderly man with hands folded, saying a prayer over a table with a simple meal. In 2002, an act of the Minnesota State Legislature established it as the state photograph. The original photograph was taken at Enstrom's photography studio in Bovey, Minnesota. Most sources indicate 1918 as the year, though Enstrom's daughter Rhoda, born in 1917, claimed to remember being present when the photograph was taken, which might have been around 1920. The man depicted in the photograph is Charles Wilden, who earned a meager living as a peddler and lived in a sod house. While the photograph conveys a sense of piety to many viewers, according to the Enstrom family's story, the book seen in the photo is actually a dictionary. However Wilden wrote "Bible" on the waiver of rights to the photo which he signed in exchange for payment, casting doubt on whether the book seen in the photo is a Bible or other religious text. Likewise, local stories about Wilden "centered more around drinking and not accomplishing very much," than religious observation. What happened to Wilden after the photograph is unknown. In 1926, he was paid $5 by Enstrom in return for waiving his rights to the photograph; he disappeared thereafter. After the photograph became popular Enstrom attempted to track Wilden down but was unsuccessful. Numerous family members and local historians have also attempted to determine what became of Wilden but have not been able to locate definitive evidence)
