(11042) Ernstweber Main-belt Asteroid
Discovered on 3 November 1989 by E. W. Elst at La Silla.
Ernst Heinrich Weber (1795-1878) was a German physiologist who did fundamental research on the sense of touch. In his De Tactu (1834) he stated what became the Weber-Fechner Law: that there is a threshold of sensation that must be passed before an increase in the intensity of the stimulus can be detected.Naming citation (20000523/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
