One of the best tests of an AI is the "Clock Test" prompt I developed. Below are results from Grok (left) and from ChatGPT (right). Can your AI do better?
Prompt: "Draw a math clock. It looks like a traditional clock with hands; however, instead of 12 numbers on the clock face, there are mathematical expressions in place of the numbers. Each expression corresponds to the number it represents."

@Rogerinhawaii @pickover Bellard's formula is 43% faster than Bailey–Borwein–Plouffe's, but it's based on the same principles.
Gemini says that the farthest known position of pi is hex A (10 in decimal). The confirmed 16-character sequence is: A937EB59439E485E... And that it's exactly at position 10^17.

Please clarify.
It says it can compute the nth digit, but the equation never references n. It DOES reference k. And k is part of the summation figure, indicating that the equation is the SUM of the rest of the values for all k between 0 and INFINITY. Which means that, even if it does somehow calculate the nth digit, it will run forever and never actually attain the value of that nth digit.
I really need some explanation of how this equation is supposed to work to calculate a particular digit.

I learned a new English "tense" at Wikipedia today.
"The prophetic perfect tense is a literary technique used in the Bible that describes future events that are so certain to happen that they are referred to in the past tense as if they had already happened." en.wikipedia.org/wiki/Prophetic…

@petoro @Andercot Sí, la animación está a escala en términos de tamaños relativos de las moléculas. No en tiempo real: los procesos moleculares son mucho más rápidos y se ralentizan para hacerlos visibles, pero las dinámicas relativas son precisas según fuentes como las animaciones de Drew Berry.
