What Should Be Explained Better?

What is the one concept in science that you really think should be explained better to a wide audience?

I imagine the tweet got a similar spectrum of responses. And that spectrum, I think, is interesting. It ranges from very general concepts (science asks “how” and “why,” Occam’s Razor and the difference between a hypothesis and a theory, empiricism, science doesn’t prove things, etc.) to general subjects (QM, E&M, evolution) to specific topics within those (decoherence, speciation, spin-1/2 systems, Heisenberg Uncertainty Principle).

Anyone who has read this blog for a while probably knows I have a spin-1/2 particle up my, um, other spin-1/2 particle about how quantum entanglement and teleportation are presented in the press, but I wouldn’t offer that up as an example, simply because it’s too limited. It’s a symptom of a larger problem, and you don’t usually cure the problem by attacking one symptom.

So I would go with some meta-explanation about science and how it works: how we, as scientists, know what we know. That is, the reminder that what we know and find out in science does not exist in a vacuum, but is built up from accumulated knowledge, and couple this with the explanation about the process — that we try and figure out how nature works by rigorously testing hypotheses and that we are skeptics (real skeptics).

Oops

A 275-foot smokestack falls the wrong way after the demolition charges go off. I hope they blamed the kids who got to set off the detonator for screwing it up.

The Economics of Seinfeld

For example, The Bottle Deposit is tagged as arbitrage, fixed costs, incentives, variable costs

Kramer and Newman hatch a scheme to arbitrage bottles from NY, where the deposit is 5 cents, to Michigan, where the deposit is 10 cents. They can’t figure out how to make the costs work; gas is too expensive (variable costs), and there’s too much overhead (fixed costs of tolls, permits, etc.) with using a semi to haul the bottles in volume. Finally, they hatch a scheme to use a mail truck, which lowers their variable and fixed costs to zero.
