## Euclide’s Mistakes

The fifth postulate In Euclid’s geometry, regarding a plane, he uses the concepts point and straight line. He postulates, that a point and a straight line together can define a unique straight line, parallel to the given line and passing through the given point. However, he never provided a proof for this postulate – the […]

Aether Maxwell’s equations are well known, but many scientists seems to have forgotten that these equations describe an aether. Maxwell translated the works of Faraday into mathematical form, and found thereby a value c on the speed of light. However, his theory is not complete, since he could not say what this speed was related […]

An earlier contribution from this author was called The Definition of Parallelism. The article stated that the definition of parallelism in Euclidean geometry is wrong. The motivation was that the lack of a point common to two lines was used in the definition. Instead it was stated that only existing concepts should be used in a […]

The geometry inside a plane includes straight lies of infinite lengths falling inside a plane. It is regarded as a fact that two points inside a plane can define a unique straight line. By intuition we assume that one point and one line also can define a unique straight line if we demand the defined line to be […]
