It is commonly thought to be named after the Nobel Laureate Eduard Buchner (without umlaut), but it is actually named after the industrial chemist Ernst Büchner. [2] A Büchner funnel fitted with Sintered Disc made of Boro 3.3 Glass. Diagram of filtration set-up using a Büchner flask
The human musculoskeletal system (also known as the human locomotor system, and previously the activity system) is an organ system that gives humans the ability to move using their muscular and skeletal systems.
A funnel (E) contains a sample of soil or leaf litter (D), and a heat source (F), in this case an electric lamp (G), heats the sample. Animals escaping from the desiccation of the sample descend through a filter (C) into a preservative liquid (A) in a receptacle (B).
Büchner flask A Büchner funnel is attached to the flask via a black elastomer adapter. The hose barb is connected via vacuum hose to a vacuum source such as an aspirator. ...

Büchner was born at Darmstadt on 29 March 1824. From 1842 to 1848 he studied physics, chemistry, botany, mineralogy, philosophy and medicine at the University of Giessen, where he graduated in 1848 with a dissertation entitled Beiträge zur Hall'schen Lehre von einem excitomotorischen Nervensystem (Contributions to the Hallerian Theory of an Excitomotor Nervous System).
The mathematical statement of the three-body problem can be given in terms of the Newtonian equations of motion for vector positions = (,,) of three gravitationally interacting bodies with masses :
The Buchner ring expansion is a two-step organic C-C bond forming reaction used to access 7-membered rings. The first step involves formation of a carbene from ethyl diazoacetate , which cyclopropanates an aromatic ring.
