As promised, here is a link to the commencement address by Richard Feinman: http://calteches.library.caltech.edu/3043/1/CargoCult.pdf. Thinking about what science actually is, is a subject near and dear to me. My graduate work was in ‘uncertainty analysis’ – as it applies to toxicology and many of the jobs I’ve held involved critiquing publications. That said, there is being a critical thinker and then there is hubris and self deception. Choosing your sources and keeping track of the limits of your knowledge is critical too, especially in our times of ‘fake news’ and ‘alternative facts’. To be clear, I’m no moronic climate change denier or dim witted Neaderthalish creationist. (Sorry, not fair to Neanderthals).
Anyway – I thought I’d throw up a few pics of clinging, or flat headed nymphs so you could see what I’m talking about:
Here is a young Epeorus. Note the two tails, the lack of wing buds (it is young) and the broader head than body. Also note the position of the eyes – pointing up rather than to the sides of the head.
This guy is a Maccaffertium as per bugguide.net – again, notice the broader head than shoulders (thorax) and body (abdomen). Eyes on top of the head. Also note the broad crab like legs.
Lastly, here is a link to that clinger pattern from Gink and Gasoline. Should be fun to try:
