Categories (Aristotle) The Categories (Greek Κατηγορίαι Katēgoriai; Latin Categoriae or Praedicamenta) is a text from Aristotle 's Organon that enumerates all the possible kinds of things that can be the subject or the predicate of a proposition. They are "perhaps the single most heavily discussed of all Aristotelian notions". [ 1 ]
Categoriae decem. The Categoriae decem (Latin for "The Ten Categories"), also known as the Paraphrasis Themistiana ("Themistian Paraphrase"), is a Latin summary of Aristotle 's Categories thought to date to the 4th century AD. Traditionally credited to St Augustine, it is now variously attributed to Themistius or Pseudo-Augustinus. [1][2]
The Rijndael S-box was specifically designed to be resistant to linear and differential cryptanalysis. This was done by minimizing the correlation between linear transformations of input/output bits, and at the same time minimizing the difference propagation probability.
AES is a variant of Rijndael, with a fixed block size of 128 bits, and a key size of 128, 192, or 256 bits. By contrast, Rijndael per se is specified with block and key sizes that may be any multiple of 32 bits, with a minimum of 128 and a maximum of 256 bits. Most AES calculations are done in a particular finite field.
AES key schedule for a 128-bit key. Define: N as the length of the key in 32-bit words: 4 words for AES-128, 6 words for AES-192, and 8 words for AES-256; K 0, K 1, ... K N-1 as the 32-bit words of the original key; R as the number of round keys needed: 11 round keys for AES-128, 13 keys for AES-192, and 15 keys for AES-256 [note 4] W 0, W 1, ...
The meaning of physics in Aristotle. It is a collection of treatises or lessons that deals with the most general (philosophical) principles of natural or moving things, both living and non-living, rather than physical theories (in the modern sense) or investigations of the particular contents of the universe. The chief purpose of the work is to ...
Aristotle [A] (Greek: Ἀριστοτέλης Aristotélēs; [B] 384–322 BC) was an Ancient Greek philosopher and polymath.His writings cover a broad range of subjects spanning the natural sciences, philosophy, linguistics, economics, politics, psychology, and the arts.
Organon. The Organon (Ancient Greek: Ὄργανον, meaning "instrument, tool, organ") is the standard collection of Aristotle 's six works on logical analysis and dialectic. The name Organon was given by Aristotle's followers, the Peripatetics, who maintained against the Stoics that Logic was "an instrument" of Philosophy. [1]
