Unreferenced stub auto yes date December 2009 An einstein is a physical unit unit used in irradiance and in photochemistry . One einstein is defined as one Mole unit mole of photon s, regardless of their frequency . Therefore, the number of photons in an einstein is Avogadro s number , 6.022 10 sup 23 sup . Irradiance might be measured in einsteins per square metre per second , if the frequency is well defined, as for a monochromatic source. If the optical frequency is not well defined this is a sloppy misuse of the term irradiance, which is defined in terms of power per unit area. The einstein is used in studies of photosynthesis since the light requirement for the production of a given quantity of oxygen is a fixed number of photosynthetically active photons about nine photosynthetically active einsteins per mole of oxygen formed . It is named in honor of Albert Einstein , who in a 1905 paper explained the photoelectric effect in terms of light quanta , now called photons, an idea introduced by Max Planck . Photosynthetically active radiation PAR is usually reported in microeinsteins per second per square meter, one microeinstein being one millionth of an einstein.

Named HEAO B before launch, the observatory s name was changed to honor Albert Einstein upon its successfully attaining orbit. Instrumentation The Einstein Observatory, HEAO 2, was launched on November 13, 1978, from Cape Canaveral, Florida , on an Atlas Centaur SLV 3D booster rocket into a near circular orbit with an initial altitude slightly above 500 km. Its orbital inclination orbit was 23.5 degrees The Einstein Observatory carried a single large Wolter telescope grazing incidence focusing X ray telescope that provided unprecedented levels of sensitivity hundreds of times better than previously achieved and arc second angular resolution of point sources and extended objects. It had instruments sensitive in the 0.2 to 3.5 keV energy range. A collection of four focal plane instruments was installed in the satellite HRI, or High Resolution Imaging camera, 0.15 3 keV IPC, or Imaging Proportional Counter, 0.4 to 4 keV SSS, or Solid State Spectrometer, 0.5 to 4.5 keV FPCS, or Bragg Focal Plane Crystal Spectrometer MPC, Monitor Proportional Counter, 1 20 keV BBFS, Broad Band Filter Spectrometer OGS, Objective grating spectrometer The Einstein Observatory satellite re entered the Earth s atmosphere and burned up on March 25, 1982.
