    • n beaver A rodent quadruped, about two feet in length, of the family Castoridæ and genus Castor, C. fiber, at one time common in the northern regions of both hemispheres, now found in considerable numbers only in North America, but occurring solitary in central Europe and Asia. It has short ears, a blunt nose, small fore feet, large webbed hind feet, with a flat ovate tail covered with scales'on its upper surface. It is valued for its fur (which used to be largely employed in the manufacture of hats, but for which silk is now for the most part substituted) and for an odoriferous secretion named castor or castoreum (which see). Its food consists of the bark of trees, leaves, roots, and berries. The favorite haunts of the beavers are rivers and lakes which are bordered by forests. When they find a stream not sufficiently deep for their purpose, they throw across it a dam constructed with great ingenuity of wood, stones, and mud, gnawing down small trees for the purpose, and compacting the mud by blows of their powerful tails. In winter they live in houses, which are from 3 to 4 feet high, are built on the water's edge with subaqueous entrances, and afford them protection from wolves and other wild animals. They formerly abounded throughout northern America, but are now found only in unsettled or thinly populated regions. Several slightly different varieties of the European beaver have received special names. The North American beaver is somewhat larger than the European, and exhibits some slight cranial peculiarities; it is commonly rated as a distinct species or conspecies, under the name of Castor canadensis. The so-called fossil beaver, Castoroides ohioensis, belongs to a different family, Castoroididæ (which see). See also Castoridæ.

    • n beaver In medieval armor, originally a protection for the lower part of the face and cheeks, fixed securely to the armor of the neck and breast, and sufficiently large to allow the head to turn behind it. In this form it was worn throughout the fifteenth century with headpieces other than the armet. In English armor it was the movable protection for the lower part of the face, while the vizor covered the upper part; it is therefore nearly the same as the aventaile (which see). In the sixteenth century the movable beaver was confounded with the vizor.

Indeterminism and Randomness Through Physics
Other examples of non-computable numbers are known: the Chaitin’s constant Ω ; the real number such that its n-th digits equals 1 if a given universal TM halts for input n, and 0 otherwise (see); the real number whose digits express the solutions of the busy beaver problem.
A definable number which cannot be approximated algorithmically
Solving the halting problem for smal l machines D(n), like m(s) and C (s), is a non-computable function, but one may use the results from a problem popular among computer scientists called the Busy Beaver problem.
Assessing Cognitive Randomness: A Kolmogorov Complexity Approach
The Busy Beaver problem is the problem of finding a value Σ(n) for the maximum number of 1s a TM with n states can produce before halting, when starting from an empty input.
