Acrostic No. 63

A hidden sentence, revealed by the answers to its clues. The clock starts when you press start — not before.

How to play
  1. The board is a hidden sentence, one square per letter.
  2. Answer a clue and its letters appear in the sentence, wherever they belong.
  3. Or type a word you can read out of the sentence — it fills in where it stands, and completes the answers those letters belong to.
  4. Every letter belongs to exactly one answer, and nothing is marked wrong: a word that is not in the puzzle simply does not take.

Quote
Arthur C. Clarke
Profiles of the Future · the third of Clarke's three laws · 1973

Clarke added it to the 1973 revised edition of Profiles of the Future, his book of predictions, to join two laws he had already published. He explained that three laws had been enough for Newton, so he would modestly stop there.

Clues

Two ways in. Type an answer from the list above and its letters appear in the sentence. Or type a word you can guess from the sentence itself — it fills in where it stands, and completes the answers those letters belong to. Every letter of the sentence belongs to exactly one answer, and the small number on a tile is its position in the sentence. Hover a clue to see which tiles it owns.
