Physics:Hydroscope

From HandWiki

A hydroscope is any of several instruments related to water:

  • One kind is an instrument for making observations below the surface of water,[1] such as a long tube fitted with various lenses arranged so that objects lying at the bottom can be reflected upon a screen on the deck of the ship that carries it. These are built with a large tire tube that supports the screen and covered by an acrylic dome for protection.[2]
  • Another kind detects subsurface water through nuclear magnetic resonance using the surface nuclear magnetic resonance technique.
  • An instrument (likely a hydrometer[3][4]) described by Synesius in his Letter 15 to Hypatia, written in 402 AD.[5][6] There are references to such instruments as early as the fourth century.[7]
  • Another ancient Greek instrument: a water clock or clepsydra.[4]
