In memoriam of the first moonwalker, Neil Armstrong, today’s fun fact is about the moonwalkers:
Nine manned missions to the moon have taken place since 1968 when the Apollo 8 mission was launched, and all have been undertaken by the United
States. Of those missions (Apollo 8, 10-17), six (Apollo 11, 12, 14-17) landed on the moon. The following is the list of people who have been to the moon (meaning they have at least been in orbit around the moon), in order of date orbited, then rank for mission. Those marked with an asterisk (*) walked on the moon during the indicated mission, those marked with a caret (^) are appearing on the list for a second time.
Apollo 8: Commander Frank Borman II

A lacuna is the untranslatability of a word from a given language to another, or the accidental absence of a word that is allowed by that languages grammatical rules. In the case of accidental absence, you can turn some verbs in English (recite, arrive, etc.) into nouns by dropping the “e” and adding “al” (recital, arrival). However, describe does not have it’s noun form (describal). Similarly, in English, there is no gender neutral form of “uncle” or “aunt”, and there are no male or female forms of “cousin”. In the case of untranslatability a concept that has a word in one language might not have a word in another. For example, English has no word for someone who is not a virgin (specifically no noun), Romanian has no word for shallow (as in shallow water) and Welsh has no word for 11 (really it’s something like tenty one, but that’s two words so it doesn’t count). Untranslatability is overcome by borrowing words from other languages, creating new words, or translating into a phrase in order to convey that missing concept.
Sharks are arguably the oldest family of large animals still alive, with the oldest accepted shark fossil being about 420 million years old, predating the dinosaurs, land animals, and even land plantlife. Sharks as a group have survived four major mass extinctions, each of which had killed at least 70% of all species then living on the planet. Sharks have a great sense of smell, able to detect blood in a concentration of one part per million (for every drop of blood, there are 1 million drops of water), and they have another sense called electroreception, which allows them to detect Earth’s magnetic field…and any movement of nearby prey. Only four shark species (great white, tiger, bull and oceanic whitetip) produce a significant number of fatal shark attacks. Sharks in general, and those four in particular, are the top predators of their environment, and like many other natural hunters, are curious of unfamiliar creatures (read: humans). However, they lack any means to explore the unknown other than their mouth, which can explain some shark attacks considering humans are generally not sufficient prey to warrant feeding as a reason to attack. On average, there is less than one death from a shark attack each year while there are, on average, forty deaths from lightning strike. Finally, the eggs of the grey nurse shark hatch inside the mother and when the first embryo develops, it eats its sibling’s embryos and any unhatched eggs. Talk about sibling rivalry.
Notice: the following post is an obligatory fulfillment of Godwin’s Law, which may or may not be discussed in a later post.
Beginning in 1942 Nazi Germany devised Operation Bernhard, a plan to bomb and demolish the British economy. Using prisoners primarily from Sachsenhausen but also Auschwitz and other concentration camps, SS Major Krüger directed a team of about 140 prisoners to forge £5, £10, £20 and £50 notes which, at the program’s end in 1945, would end up totaling £134,610,810. The forged notes are considered the best counterfeits ever produced, being virtually indistinguishable from official Bank of England notes. The notes were never dropped on England, but were used by the Nazi foreign intelligence to pay for their activities. In early 1945 another similar operation was in the works to forge American $100 bills, but was cancelled one day after starting.
Of the three types of football only one (association football, aka soccer) is played regularly at the Olympics [Association football has been an event in every Summer Olympic Games except the 1896 and 1932 Games]. Rugby union was a part of the men’s competitions at the 1900, 1908, 1920 and 1924 Summer Olympics and Rugby sevens is expected to be played at the 2016 Summer Olympics in Rio de Janiero. Gridiron (aka American) football has never been played at the Olympics, but used to be so similar to rugby union that the American team actually took home the gold medal in the 1920 and 1924 competitions.
Today’s fun fact is from the original Facebook posts:
The national bird of the United States, the Bald Eagle, can be found in the wild in any state except Hawaii. With a range that stretches from Alaska, though Canada and the Lower 48, and into Northern Mexico, the population of the Bald Eagle is thriving and was removed from the Threatened Wildlife lists of the Lower 48 states in June 2007. The nests of Bald Eagles can weigh up to 1 ton, and are the biggest of any North American bird. The Bald Eagle’s Eurasian cousin, the White-tailed eagle (which resembles the Bald Eagle, but with a brown head), can typically be found in North and East Europe, but has pocket ranges from Greenland to Japan and from Iran to Russia. On average, the White-tailed Eagle is slightly larger than the Bald Eagle, but lacks the distinction of being a national symbol.
If Earth were to be replaced by an Earth-mass black hole, almost nothing in the universe would change. It wouldn’t start sucking things up, there would be no major gravitational disturbances, nothing. All that would happen is that anything that passed through a region the size of a peanut would be absorbed into the black hole, and anything that passed nearby would be distorted. All objects have an event horizon (the surface of a black hole), but most objects are far larger than their event horizon (a black hole with Earth’s mass is about the size of a peanut). Black holes also have something called a photon sphere, where photons (light waves/particles) orbit the black hole. Finally, if you were to try and fall into a black hole (for science of course) you would experience a process known as spaghettification. Since, as you approach the black hole, the parts of your body closest to the black hole are being pulled harder by gravity than those far away, you will be stretched, slowly are first but then more quickly, until all of your body is within the event horizon. What happens then? Nobody knows. The current mathematical models used in physics cannot describe what happens within the event horizon of the black hole.
