Element 105 carries the name hahnium in recognition of his work. Russian physicist who, in experiments with William Crookes' radiometer, proved (1910) that light exerts a minute pressure on bodies (as predicted by James Clerk Maxwell's theory of electromagnetism), and furthermore that this effect is twice as great for reflecting surfaces than for absorbent surfaces.He had proposed that light pressure on small particles of cosmic dust could be greater than gravitational attraction, thus explaining why a comet's tail points away from the Sun (though it is now understood the solar wind has a greater influence).This was a method of synthesizing hydrocarbons or ketones from aromatic hydrocarbons using aluminum chloride as a catalyst.Friedel and Crafts also did much work on the synthesis of organosilicon compounds.
Karl (Immanuel Eberhard) von Goebel was a German botanist whose Organographie der Pflanzen (1898-1901; Organography of Plants, 1900-05) clarified the principles of the science of plant morphology in relation to form and structure.
