1 + 2 + 4 + 8 + ⋯ that and , but the underlying proofs demand careful thinking about the interpretation of endless sums. It is also possible to view this series as convergent in a number system different from the real numbers, namely, the 2-adic numbers. As a series of 2-adic numbers this series converges to the same sum, −1, as was derived above by analytic continuation. 1 + 2 + 4 + 8 + ⋯ In mathematics, is the infinite series whose terms are the successive powers of two. As a geometric series, it is characterized by its first term, 1, and its common ratio, 2.
Minim (palaeography) Minim (palaeography) In palaeography, a minim is a short, vertical stroke used in handwriting. The word is derived from the Latin "minimum", meaning "least" or "smallest". A minim is the basic stroke for the letters i, m, n, and u in uncial script and later scripts deriving from it. Parts of other letters are based on minims as well: when a minim is extended above the line, it becomes an "ascender", as in the letters d and b, and when it is extended below the line, it becomes a "descender", as in the letters p and q. It is a
