Four short posts
Orbits, primes, fractals, and pyramids
The Artemis II crew should land in Pacific ocean tomorrow night. This mission is interesting because it carries a crew, but the Artemis I uncrewed mission is more interesting in terms of orbital mechanics. And the upper stage of Apollo 12 is even more interesting. More here.
Andrica’s conjecture says that the square roots of consecutive primes are less than 1 apart. More here.
You can construct a fractal by repeatedly choosing a side of a hexagon randomly and finding the center of a triangle. Different definitions of “center” result in different fractals. More here.
There’s a coincidence between the speed of light and the latitude of the Great Pyramid of Giza. More here.
Have fun.
