Undergrad Is infinity a necessary concept?
Infinity is for example necessary to write transcendental functions via their Taylor series (if it exists). ##e^x = 1 + x + \frac{x^2}{2!} + \frac{x^3}{3!} + \cdots##- Sagittarius A-Star

Method of storing energy on the Moon
NASA’s Apollo missions - from Apollo 12 on - used Plutonium-238 to power the Apollo Lunar Surface Experiments Package (ALSEP), except Apollo 13. The 4 kg Plutonium of Apollo 13 fall into the pacific ocean on Earth, because the LM was returned to Earth. Source...- Sagittarius A-Star
