1/4 + 1/16 + 1/64 + 1/256 + ⋯. Archimedes' figure with a = 3 4. In mathematics, the infinite series 1 4 + 1 16 + 1 64 + 1 256 + ⋯ is an example of one of the first infinite series to be summed in the history of mathematics; it was used by Archimedes circa 250–200 BC. [1] As it is a geometric series with first term 1 4 and common ratio 1 4 ...

1,3-Indandione (sometimes simply indanedione) is an organic compound with the molecular formula C 6 H 4 (CO) 2 CH 2. It is a β-diketone with indane as its structural nucleus. It is a colorless or white solid, but old samples can appear yellowish [3] or even green. It is a popular chemical scaffold (building block of various useful chemical ...
ATD has many names in sports supplements including: 1,4,6 etiollochan-dione, 3, 17-keto-etiochol-triene, androst-1,4,6-triene-3,17-dione and many others. These all refer to CAS# 633-35-2. ATD may cause a positive test for the anabolic steroid Boldenone, of which it is a possible metabolite and production contaminant. ATD is also prohibited in ...
