    In chemistry, the Fischer projection, devised by Emil Fischer in 1891, is a two-dimensional representation of a three-dimensional organic molecule by projection. Fischer projections were originally proposed for the depiction of carbohydrates and used by chemists, particularly in organic chemistry and biochemistry. The use of Fischer projections ...

    The book was also believed to be a source of inspiration to David Hahn, nicknamed "the Radioactive Boy Scout" by the media, who attempted to construct a nuclear reactor in his mother's shed, [2] although the book does not include any nuclear reactions. Due to safety concerns, the book was eventually pulled from library shelves. [3]

  7. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    Expressing resonance when drawing Lewis structures may be done either by drawing each of the possible resonance forms and placing double-headed arrows between them or by using dashed lines to represent the partial bonds (although the latter is a good representation of the resonance hybrid which is not, formally speaking, a Lewis structure).
