The geometric series on the real line. In mathematics, the infinite series 1 2 + 1 4 + 1 8 + 1 16 + ··· is an elementary example of a geometric series that converges absolutely. The sum of the series is 1. In summation notation, this may be expressed as. The series is related to philosophical questions considered in antiquity, particularly ...

Ranma ½: Rock-Scissors-Puzzle (Ranma ½: Ougi Jaanken) A puzzle game based on rock, paper, scissors. Hands are dropped showing the rock, paper, and scissor signs and are used to remove other hands that have the opposite sign. Its Japanese name is composed of ougi (meaning secret) and jaanken, a play on the word janken (the Japanese name for ...
CClF 2 CCl 2 F → C 2 F 3 Cl 2 + Cl• Cl• + O 3 → ClO• + O 2. This reaction is followed by: ClO• + O → Cl• + O 2. The process regenerates Cl• to destroy more O 3. The Cl• will destroy an average of 100,000 O 3 molecules during its atmospheric lifetime of 1–2 years. In some parts of the world, these reactions have ...
Roblox, for instance, has faced criticism for its AI-generated game assets, which have the potential to flood the platform with low-quality, derivative content, potentially drowning out human ...
2/1 game forcing ( Two-over-one game forcing) is a bidding system in modern contract bridge structured around the following responses to a one-level opening bid: a non-jump response in a new suit at the one-level is constructive and forcing for one round, a non-jump response in a new suit at the two-level is forcing to game, and.
The first step is the liquid- or vapour-phase chlorination of butadiene to a mixture of 3,4-dichlorobut-1-ene and 1,4-dichlorobut-2-ene (both isomers). In the second step, the mixture of 1,4-dichlorobut-2-ene and 3,4-dichlorobut-1-ene is isomerized to 3,4-dichlorobut-1-ene by heating to temperatures of 60–120 °C in the presence of a catalyst.
