Why Did Lagrange "Prove" the Parallel Postulate?
1. INTRODUCTION. We begin with an often-told story from the Budget of Paradoxes by Augustus de Morgan: " Lagrange, in one of the later years of his life, imagined " that he had solved the problem of proving Euclid's parallel postulate. " He went so far as to write a paper, which he took with him to the [Institut de France], and began to read it. " But, De Morgan continues, " something struck hi...
متن کاملConstructive Geometry and the Parallel Postulate
Euclidean geometry, as presented by Euclid, consists of straightedge-andcompass constructions and rigorous reasoning about the results of those constructions. We show that Euclidean geometry can be developed using only intuitionistic logic. This involves finding “uniform” constructions where normally a case distinction is used. For example, in finding a perpendicular to line L through point p, ...
متن کاملQ&A: What did Charles Darwin prove?
It is often said that Darwin’s theory of natural selection is unproven True? I don’t think that is a very useful question because Darwin’s strength comes not so much from what he proved, but from the near-inescapable conclusions that he led us to. He used every means of informing himself about questions that interested him. He is known for his massive and continuous correspondence, always askin...
متن کاملDid Einstein prove E 1⁄4 mc 2 ?
Although Einstein’s name is closely linked with the celebrated relation E 1⁄4 mc between mass and energy, a critical examination of the more than half dozen ‘‘proofs’’ of this relation that Einstein produced over a span of forty years reveals that all these proofs suffer from mistakes. Einstein introduced unjustified assumptions, committed fatal errors in logic, or adopted low-speed, restrictiv...
متن کاملThe Parallel Postulate in Constructive Geometry
Euclidean geometry, as presented by Euclid, consists of straightedge-and-compass constructions and rigorous reasoning about the results of those constructions. A consideration of the relation of the Euclidean “constructions” to “constructive mathematics” leads to the development of a first-order theory ECG of the “Euclidean Constructive Geometry”, which can serve as an axiomatization of Euclid ...
