Shared publicly -What? Gotta go back to the map. I obviously made a wrong turn somewhere. This is not the right planet. ;p

The DeLorean is going back to the future and into production. We first saw the time machine three decades ago in the movie, Back to the Future. But the last time a DeLorean was built was about 35 years ago. Soon that will change at the DeLorean Motor Company in Humble.

https://en.wikipedia.org/wiki/Squaring_the_circle .... Squaring the circle is a problem proposed by ancient geometers. It is the challenge of constructing a square with the same area as a given circle by using only a finite number of steps with compass and straightedge. More abstractly and more precisely, it may be taken to ask whether specified axioms of Euclidean geometry concerning the existence of lines and circles entail the existence of such a square.

In 1882, the task was proven to be impossible, as a consequence of the Lindemann–Weierstrass theorem which proves that pi (π) is a transcendental, rather than an algebraic irrational number; that is, it is not the root of any polynomial with rational coefficients. It had been known for some decades before then that the construction would be impossible if pi were transcendental, but pi was not proven transcendental until 1882. Approximate squaring to any given non-perfect accuracy, in contrast, is possible in a finite number of steps, since there are rational numbers arbitrarily close to π.

The expression "squaring the circle" is sometimes used as a metaphor for trying to do the impossible

Shared publicly -Looks good to me.

No one can learn it all overnight, and sometimes, you won’t have a teacher. D&D for Young Players and DMs is a journal of the lessons our family learned while introducing my kids to D&D.
