Negative Time Iteration
- theamk 8y agoIt's interesting that author has chosen to time-reverse Fibonacci sequence, which is cleanly defined on negative values (although alternating signs are somewhat unusual) Then they start to talk about imperative programming and its inability to reverse time, completely ignoring the fact that many mathematical functions defined by recurrences, like factorial, are irreversible.
- dang 8y agoWadge is a mathematician, so he knows that. Presumably he simply chose an example that fits the material. "Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize."
