Quotations for Today
"This is only one step in a much larger project. I discovered (no, not me: my team) the function of sugar nucleotides in cell metabolism. I want others to understood this, but it is not easy to explain: this is not a very noteworthy deed, and we hardly know even a little." - Luis Federico Leloir (born 6 Sep 1906) replying when asked about the significance of his Nobel prize-winning achievement.

"... the history of science has proved that fundamental research is the lifeblood of individual progress and that the ideas that lead to spectacular advances spring from it." - Sir Edward Appleton (born 6 Sep 1892)

"Chemical analysis and synthesis go no further than to the separation of particles one from another, and to their reunion. No new creation or destruction of matter is within the reach of chemical agency. We might as well attempt to introduce a new planet into the solar system, or to annihilate one already in existence, as to create or destroy a particle of hydrogen." - English chemist in quiz below (born 6 Sep 1766).
