Quotations for Today
"What, then, is it in particular that can be learned from teachers of special distinction? Above all, what they teach is high standards. We measure everything, including ourselves, by comparisons; and in the absence of someone with outstanding ability there is a risk that we come to believe that we are excellent and much better than the next man. Mediocre people may appear big to themselves (and to others) if they are surrounded by small circumstances. But the same token, big people feel dwarfed in the company of giants, and this is a most useful feeling. So what the giants of science teach us is to see ourselves modestly and not to overrate ourselves." - Sir Hans Adolf Krebs (born 25 Aug 1900)

"We see it (the planet in quiz below) as Columbus saw America from the coast of Spain. Its movements have been felt, trembling along the far-reaching line of our analysis with a certainty hardly inferior to that of ocular demonstration." - Sir William Herschel (died 25 Aug 1822)

"I am busy just now on electro-magnetism, and think I have got a hold of a good thing, but can't say. It may be a weed instead of a fish that, after all my labour, I may at last pull up." - scientist in quiz below (died 25 Aug 1867)
