comment Tidy form of numbers with errors using ScientificForm
@bbgodfrey (1) This is defined upon a System` operator so it is global. One could use a head besides PlusMinus at the expense of the pretty entry form. (2) I would be happy to but what would you like explained?

comment Transpose four lists of data into two lists for use in List Plot
@olliepower Well your code would work with a single character change, which is to change @@ to @@@, giving Apply at level one rather than level zero: Transpose[{#1, #2}] & @@@ {{x1, y1}, {x2, y2}}. However this is a rather round-about way to go as you first disassemble each list and then put it back together in the same order, then Transpose.
