1. Palindrome

   A palindrome is a word, number, phrase, or other sequence of symbols that reads the same backwards as forwards, such as the words madam or racecar, the date and time 12/21/33 12:21, and the sentence: "A man, a plan, a canal – Panama". The 19-letter Finnish word saippuakivikauppias (a soapstone vendor), is the longest single-word palindrome in everyday use, while the 12-letter term tattarrattat (from James Joyce in Ulysses) is the longest in English. The word palindrome was introduced by English poet and writer Henry Peacham in 1638. The concept of a palindrome can be dated to the 3rd-century BCE, although no examples survive; the first physical examples can be dated to the 1st-century CE with the Latin acrostic word square, the Sator Square (contains both word and sentence palindromes), and the 4th-century Greek Byzantine sentence palindrome nipson anomemata me monan opsin.Palindrome are also found in music (the table canon and crab canon) and biological structures (most genomes include palindromic gene sequences). In automata theory, the set of all palindromes over an alphabet is a context-free language, but it is not regular.

1. Palindrome

   A palindrome is a word, phrase, number, or other sequence of symbols or elements, whose meaning may be interpreted the same way in either forward or reverse direction. Composing literature in palindromes is an example of constrained writing. The word "palindrome" was coined from the Greek roots palin and dromos by the English writer Ben Jonson in the 17th century. The Greek phrase to describe the phenomenon is karkinikê epigrafê, or simply karkinoi, alluding to the movement of crabs, such as an inscription that may be read backwards.

   But under the conditions of warfare, weapons are going to have performance characteristics. And they're going to be very carefully fashioned for that purpose because it matters... You would cut somebody [ with a mata'a ], but they certainly wouldn't be lethal in any way.

One theory suggests that the deforestation led to soil erosion, impacting the island’s ability to support wildlife and farming, and the collapse of its civilization. When the Dutch arrived at the island in 1722, its population was 3,000 or less. Only 111 inhabitants were living on Easter Island by 1877. Other experts, however, have questioned whether Easter Island ever supported a large population, citing instead the arrival of Europeans, who brought diseases and took islanders away as slaves.
