Henri ’ s Crystal Ball

O n April 10, 1908, at the general session of the Fourth International Congress of Mathematicians held in Rome, Gaston Darboux presented a talk by Henri Poincaré (1854–1912) entitled The Future of Mathematics (Poincaré was unfortunately unable to deliver the talk himself). The original can be found on the web at: http://gallica. bnf.fr/ark:/12148/bpt6k17083c/f934n10. capture. It is now a full c...

Hubble ’ s Nobel Prize D . S . L .

Astronomy is not in the list of natural sciences aimed at by the Nobel awards. In spite of that, there were, throughout the 1930s until the early 1950s, effective moves by important scientists to distinguish Hubble with the Prize. A short report on these attempts is made as well as speculation on what would be the citation for the prize in view of the broad range of Hubble's scientific achievem...

Signed Graph Equation L K ( S ) ∼ S

A Smarandachely k-signed graph (Smarandachely k-marked graph) is an ordered pair S = (G,σ) (S = (G,μ)), where G = (V, E) is a graph called the underlying graph of S and σ : E → (e1, e2, · · · , ek) (μ : V → (e1, e2, · · · , ek)) is a function, where each ei ∈ {+,−}. Particularly, a Smarandachely 2-singed graph or 2-marked graph is called abbreviated to a singed graph or a marked graph. We chara...

Sets play a key role in foundations of mathematics. Why? To what extent is it an accident of history? Imagine that you have a chance to talk to mathematicians from a far away planet. Would their mathematics be setbased? What are the alternatives to the set-theoretic foundation of mathematics? Besides, set theory seems to play a significant role in computer science, in particular in database the...
