Jean-Claude Bradley presents at a panel at Lawrence Sowder's class on Rhetoric of Science at Drexel University on October 6, 2010.

  1. 1. The meaning of data<br />Rhetoric of Science Panel <br />COM400 Class at Drexel University<br />Jean-Claude Bradley<br />Associate Professor of Chemistry<br />Drexel University<br />October 6, 2010<br />
  2. 2. There are NO FACTS, <br />only measurements <br />embedded within assumptions<br />
  3. 3. In principle one experiment is enough to invalidate a theory<br />In practice, it takes a lot more than one experiment to make any progress because uncertainty is unavoidable<br />
  4. 4. How bad is our current system? Try to find the solubility EGCG?<br />
  5. 5. Contradictions are common<br />=2.3 g/L<br />
  6. 6. Uncertainty is unavoidable <br />But it can be reduced with transparency<br />
  7. 7. TRUST<br />PROOF<br />
  8. 8. Data provenance: <br />From Wikipedia to…<br />
  9. 9. …the lab notebook and raw data<br />
  10. 10. Interactive NMR spectra using JSpecView and JCAMP-DX<br />
  11. 11. Raw Data As Images<br />Splatter?<br />Some liquid<br />
  12. 12. YouTube for demonstrating experimental set-up<br />
  13. 13. Scientists don’t deal in facts – they deal in evidence<br />Scientists are comfortable with ambiguity and use fuzzy logic to solve problems<br />
