  2. Brandolini's law - Wikipedia

    en.wikipedia.org/wiki/Brandolini's_law

    In order to refute misinformation, one needs to do the following: [19] Be correct by including all necessary information that was run by a friend and double checking facts. Be charitable by acknowledging the possibility of your own confusion, not attributing malice, and not assigning stupidity. Be clear and coherent about the argument you are ...

  3. Derangement - Wikipedia

    en.wikipedia.org/wiki/Derangement

    The above semi-log graph shows that the derangement graph lags the permutation graph by an almost constant value. More information about this calculation and the above limit may be found in the article on the statistics of random permutations .

  4. Mathematical constant - Wikipedia

    en.wikipedia.org/wiki/Mathematical_constant

    The circumference of a circle with diameter 1 is π.. A mathematical constant is a number whose value is fixed by an unambiguous definition, often referred to by a special symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]

  5. Liu Hui's π algorithm - Wikipedia

    en.wikipedia.org/wiki/Liu_Hui's_π_algorithm

    Liu Hui's method of calculating the area of a circle. Liu Hui's π algorithm was invented by Liu Hui (fl. 3rd century), a mathematician of the state of Cao Wei.Before his time, the ratio of the circumference of a circle to its diameter was often taken experimentally as three in China, while Zhang Heng (78–139) rendered it as 3.1724 (from the proportion of the celestial circle to the diameter ...

  6. Paradox of value - Wikipedia

    en.wikipedia.org/wiki/Paradox_of_value

    In the paradox of value, it is a contradiction that it is cheaper than diamonds, despite diamonds not having such an importance to life. The paradox of value, also known as the diamond–water paradox, is the paradox that, although water is on the whole more useful in terms of survival than diamonds, diamonds command a higher price in the market.

    Those on the other side of the argument — including many teachers and education experts — say cursive may have some value but is far less important than the things that would have to be set ...

  8. Omnipotence paradox - Wikipedia

    en.wikipedia.org/wiki/Omnipotence_paradox

    The follow on question "Then can he lift it?" assumes that the rock has already been created, so the correct answer would be "Assuming he makes the rock, no". And if asked "Is God thus not all powerful?", the correct answer would be "God is indeed all powerful until such time as the rock is created". The "Paradox" then is not really a paradox.

  9. Lucas–Lehmer primality test - Wikipedia

    en.wikipedia.org/wiki/Lucas–Lehmer_primality_test

    It will produce 2 n −1 for a multiple of the modulus rather than the correct value of 0. However, this case is easy to detect and correct. However, this case is easy to detect and correct. With the modulus out of the way, the asymptotic complexity of the algorithm only depends on the multiplication algorithm used to square s at each step.
