| Quotations for Today | |
| "There are not chemists there, just a lot of paper hangers" - Robert Robinson, British Nobel prize-winning chemist (born 13 Sep 1886) referring to Frederick Sanger when, during the 1950s, Todd and co-workers were using paper chromatography to investigate degradation products of vitamin B12. "When experimental results are found to be in confliuct with those of an earlier investigator, the matter is often taken too easily and disposed of for an instance by pointing out a possible source of error in the experiments of the predessessor, but without wnquiring whether the error, if present, would be quantitatively sufficient to explain the discrepancy. I thnk that disagreement with former results should never be taken easily, but every effort should be made to find a true explanation." - August Krogh, Danish Nobel prize-winning physiologist (died 13 Sep 1949) | |
