Roman numerals: for example the word "six" in the clue might be used to indicate the letters VI; The name of a chemical element may be used to signify its symbol; e.g., W for tungsten; The days of the week; e.g., TH for Thursday; Country codes; e.g., "Switzerland" can indicate the letters CH; ICAO spelling alphabet: where Mike signifies M and ...
An American-style crossword grid layout. A crossword (or crossword puzzle) is a word game consisting of a grid of black and white squares, into which solvers enter words or phrases ("entries") crossing each other horizontally ("across") and vertically ("down") according to a set of clues. Each white square is typically filled with one letter ...
Chemical decomposition, or chemical breakdown, is the process or effect of simplifying a single chemical entity (normal molecule, reaction intermediate, etc.) into two or more fragments. [ 1] Chemical decomposition is usually regarded and defined as the exact opposite of chemical synthesis. In short, the chemical reaction in which two or more ...
The flatness problem (also known as the oldness problem) is a cosmological fine-tuning problem within the Big Bang model of the universe. Such problems arise from the observation that some of the initial conditions of the universe appear to be fine-tuned to very 'special' values, and that small deviations from these values would have extreme ...
If a starter word is given in the grid, using it as the beginning search point is often useful. Raw "trial and error" is best used when only two or three words can potentially fit at a given location; temporarily assume one of the words, and see if an impossible letter combination results.
The 42-year-old Today anchor was recently featured as an answer in The New York Times crossword on Sunday, Feb. 25, and her candid reaction to it couldn't have been scripted any better.
RXNO:0000032. In organic chemistry, the Mannich reaction is a three-component organic reaction that involves the amino alkylation of an acidic proton next to a carbonyl ( C=O) functional group by formaldehyde ( H−CHO) and a primary or secondary amine ( −NH2) or ammonia ( NH3 ). [ 1] The final product is a β-amino-carbonyl compound also ...
Flatness is the condition of a surface or derived median plane having all elements in one plane. [1] Geometric dimensioning and tolerancing has provided geometrically defined, quantitative ways of defining flatness operationally . Flatness deviation may be defined in terms of least squares fit to a plane ("statistical flatness") or worst-case ...
