I’ve always suspected that the word decal is an abbreviation for something, and today my suspicion has been vindicated. My handy Concise O.E.D. tells me that decal is an abbreviation of a word previously unknown to me, decalcomonia:
n. the process of transferring designs from prepared paper on to glass, porcelain, etc.
- Origin C19: Fr. décalcomanie, from décalquer ‘transfer a tracing’ + -manie ‘-mania’ (with ref. to the enthusiasm for the process in the 1860s).
Like with any good bit of etymology, I have now learned something about the word itself, and about the culture whence it comes. Turns out, French people in the 1800s were decal maniacs.
The Tunguska Event, or Tunguska explosion, was a massive explosion that occurred near the Podkamennaya (Lower Stony) Tunguska River in what is now Krasnoyarsk Krai of Russia, at around 7:14 a.m. (0:14 UT, 7:02 a.m. local solar time) on June 30, 1908 (June 17 in the Julian calendar, in use locally at the time).
Although the cause is the subject of some debate, the explosion was most likely caused by the air burst of a large meteoroid or comet fragment at an altitude of 5–10 kilometres (3–6 miles) above Earth’s surface. Different studies have yielded varying estimates for the object’s size, with general agreement that it was a few tens of metres across.
Although the meteor or comet burst in the air rather than directly hitting the surface, this event is still referred to as an impact event. Estimates of the energy of the blast range from 5 megatons to as high as 30 megatons of TNT, with 10–15 megatons the most likely - roughly equal to the United States’ Castle Bravo thermonuclear explosion set off in late February of 1954, about 1000 times as powerful as the bomb dropped on Hiroshima, Japan and about one third the power of the Tsar Bomba, the largest nuclear weapon ever detonated.[6] The explosion knocked over an estimated 80 million trees over 2,150 square kilometres (830 square miles). It is estimated that the earthquake from the blast would have measured 5.0 on the Richter scale, which was not yet developed at the time. An explosion of this magnitude is capable of destroying a large metropolitan area.[7] This possibility has helped to spark discussion of asteroid deflection strategies.
Although the Tunguska event is believed to be the largest impact event on land in Earth’s recent history, impacts of similar size in remote ocean areas would have gone unnoticed before the advent of global satellite monitoring in the 1960s and 1970s.

John Gossage (American, 1946- ) is an artist who makes history present in photographs. He photographs places and sites that tell an everyday story: paths worn through abandoned tracts of land, corners where debris collects, markings on a wall, a table after a meal. Gossage photographs that which has just occurred to remind us that we may have already forgotten it happened or that we were there. By asking us look at what we have misplaced or abandoned he brings us face to face with the present as it becomes history. Throughout the 1980s Berlin became Gossage’s overriding focus. Berlin, with its Wall, forgotten tracts of land, unwanted histories - both forgotten and remembered - became the place where Gossage discovered the ideas that have come to mark his personalized style of photograhic storytelling. The art from this period is arguable his most important and has unquestionable influenced all his subsequent work.
