It’s been a busy evening! Not only did we just complete our second burn, but #NASAWebb also passed the altitude of the Moon as it keeps cruising on to the second Lagrange point to #UnfoldTheUniverse. Bye, @NASAMoon! 👋 🌑
Mathematics.
A mathematician emerges from a cave, hands you the slip of paper below, and asks "Does 0.999... (consisting of an unending sequence of 9s after the decimal point) equal 1? " What is your answer?
Mathematics is the only field of human knowledge in which you have thousands of billions of clues for a prediction and it's still not enough to accept it as a valid theory.
1³+2³+3³+4³+5³+6³+...+n³=(1+2+3+4+5+6+...+n)²
Proof:
Arranging 1³+2³+3³+4³+5³+6³+...+n³ in the plane: 1x1²+2x2²+3x3²+4x4²+5x5²+6x6²+...+nxn²
The even squares overlap (🟨) but also leave uncovered gaps (🟥) and 🟨=🟥
