Gee, thanks. After my brain-stem stroke, I lost all my (formerly excellent) ability to even do simple math. So just thankyuvurrymuch for another blanket nasty generalization..............

This quote is now actually about math. it is about current competence.

Reality: the college entrance exams have damaged self esteem form way too many college grads.

98 percent of people never use more than basic math.

What's your threshold?

Do you have to understand differential equations? complex analysis? distribution theory? detection and estimation theory? log likelihood ratios? maximum likelihood decoders? Bayes' theorem? Z-transforms and discrete time systems? Laplace transforms and continuous time systems? Discrete and continuous time Fourier transforms? Joint Maximum Likelihood Sequence Estimation? Maxwell's Equations? Navier-Stokes Equations? Bessel Functions? Galois Fields? Fresnel and Fraunhofer Approximations? Diffraction Tomography?

What does "cope with mathematics" mean? Grasp the fundamentals like +-x/? Or do you have to understand some form of advanced math? If advanced, how advanced? Algebra, Trig, Cal? That's like saying if you can't sing or play a musical instrument, you're not fully human.. Is my friend William, who is autistic and can't do simple math, not fully human? I'm not thinking Mr. Heinlein is hitting on much there.
