[SEP] Knowledge 2: Upside down year
An upside down year is a year which reads the same when the' year number' is turned upside down, when the numerals which form the year's number appear the same when rotated 180 degrees( turned upside down).Mathematicians refer to this' rotationally symmetric' characteristic of the number string as a strobogrammatic number.It involves exploring the visual oddity of some number strings used for representing years.The most recent upside down year was 1961, and before that were sequentially 1881 and 1691.Before that was 1111, the year 1001 began the second millennium, and before that were 3- digit years, such as 986, 888, 689, 181, 101, etc.Using only the digits 0, 1, 6, 8 and 9, the next upside- down year will not occur until 6009.Allowing for the numbers 2, 5 and 7, the next such year will be 2112( if leading zeroes are allowed to be arbitrarily added, 2020 can be made an upside down year by making it 02020).Both 1969 and 6009 are' invertible primes' where turning the set of digits upside down( rotating it 180 degrees) yields a different prime number." Mad" magazine parodied the upside down year in March 1961.The concept of an upside- down year is dependent on typeface and number form.2 and 5 are upside down digits when using the seven bar electronic font as used widely on digital clocks, electronic meters, basic calculators, and other electronic devices that display numerical information, which would make 2002 a palindromic year and 2007 an upside- down year; it is also possible to manipulate a 7 such that it resembles an upside- down 2 and thus make 2007 an upside- down year as well.

[SEP] Knowledge 2: Upside-down catfish
The name upside- down catfish is most commonly used by aquarists to refer to the mochokid catfish" Synodontis nigriventris" alternately known to ichthyologists as the blotched upside- down catfish or false upside- down catfish.However, a number of other fish may also be known by this name:The name' dwarf upside- down catfish' is also used for small( around 10 cm) species of the catfish genus" Synodontis".In the aquarium trade, the name is almost always applied to" S. nigriventris" or species with which it may be confused, such as" S. aterrimaS. contracta", and juvenile" S. nigrita"( adults of which are around 20 cm so are not" dwarf" species at all).As its common name implies, the upside- down catfish will swim upside- down.One theory accounts for this unusual behavior as a feeding strategy.In the wild, it often grazes on the undersides of submerged branches and logs, and swimming upside- down makes these areas more accessible.A different theory suggests swimming upside- down makes aquatic surface respiration more efficient.
