Gone & (should not be) forgotten

Let's not teach students that it's only science if you get it right the first time

Sort Content Brief description Link
  A distracting genetic code Thinking about WAYS to code gave rise to a mechanism that called for 20 amino acids specifically (also of interest: non comma-free codes, etc.) PNAS paper
  Gamow and the holes-for-amino-acids A central question in information flow is how nucleic acids 'call for' amino acids. Early thinking was "because they fit together"


Nice blog summary

  Pauling's inside-out DNA It makes sense--alpha helices have the 'interesting bits' (sidechains) on the outside; for DNA, if the bases 'instruct', shouldn't the instructions face out as well? Paper (overkill)
  Phlogiston Everything about burning was backwards once. Instead of wood being reduced (able to be oxidized = gain oxygen), it contained 'phlogiston' used up by burning Wiki link
  Geocentrism Because what else are you going to put at the center of the Universe?  
  Magic, the belief system There was actually some logical thinking there--'contagion' (once together, always linked) and 'sympathy' (if two things are alike, there's a physical linkage)  
  RNA can't be an enzyme Because... hmmm. Because we've not found one that is yet?  
  'Action at a distance' Because DNA only exists in 2 dimensions  
  Alchemy Anything that gave birth to Chemistry can't be all bad...  
  The 4/5 elements An early effort to explain the diversity of substances by looking for smaller, common... elements. Now supplanted by the Periodic Table
