The Unicorn, The Normal Curve, and Other Improbable Creatures
An investigation of the distributional characteristics of 440 large-sample achievement and psychometric measures found all to be significantly nonnormal at the alpha .01 significance level.

متن کاملThe Busy Beaver, the Placid Platypus and other Crazy Creatures
The busy beaver is an example of a function which is not computable. It is based on a particular class of Turing machines, and is defined as the largest number of 1’s that can be printed by a terminating machine with n states. Whilst there have been various quests to determine the precise value of this function (which is known precisely only for n ≤ 4), our aim is not to determine this value pe...

This view has also relegated the other creatures to the level of “thing and tool” for human life. Meanwhile, the Islamic philosophy inspired by the Quran, not only considers that all...
متن کاملEvading Predictors with Creatures
We continue the theory of evasion and prediction which was introduced by Blass and developed by Brendle, Shelah, and Laflamme. We prove that for arbitrary sufficiently different f, g ∈ ωω, it is consistent to have eg < ef , where ef is the evasion number of the space ∏ n<ω f(n). For this we apply a variant of Shelah’s “creature forcing”.
متن کاملEvolving Physical Creatures
One of the prevailing characteristics of natural life is autonomy. The field of Artificial Life has so far addressed the notion of autonomy mostly in terms of power and behavior. In this paper we attempt to extend the notion of autonomy to include also design and fabrication: We claim that not only should artificial creatures be able to operate untethered and without external guidance, but they...
