AUGUST FERDINAND MOBIUS (1790-1868), German astronomer and mathematician, was born at Schulpforta on the 17th of November 1790.
Mobius must be regarded as one of the leaders in the introduction of the powerful methods of modern projective geometry.
Mobius in his Analecta norroena (2nd ed., 1877); at the same time he gave it in German in Dr Hommel's Aethiopic publication.

It is remarkable that Mobius employs the symbols AB, ABC, Abcd In Their Ordinary Geometrical Sense As Lengths, Areas And Volumes, Except That He Distinguishes Their Sign; Thus Ab = Ba, Abc= Acb, And So On.

See also the collected works of Mobius, and those of Clifford, for a general explanation of Grassmann's method.
Others, such as the Barycentrische Calciil of Mobius, and the Methode des equipollences of Bellavitis, give elegant modes of treating space problems, so long as we confine ourselves to projective geometry and matters of that order; but they are limited in their field, and therefore need not be discussed here.
MObius (1790-1868), a line such that the moment of a given wrench about it is zero is called a null-line.
The investigation of such questions forms the subject of Astatics, which has been cultivated by MObius, Minding, G.
Also, by giving suitable values (positive or negative) to the ratios a :7 we can make G assume any assigned position in the plane ABC. We have here the origin of the barycentric co-ordinates of MObius, now usually known as areal co-ordinates.

Professor Mobius is of opinion that oysters over twenty years of age are rare, and that most of the adult Schleswig oysters are seven to ten years old.
