🛸 Daily joke

I tried to write a biography about the supermassive black hole, but I couldn't find a way to wrap up the ending.

📜 Daily poem

The Lunar Excavation

A hollowed crater, deep and wide, Where Falcon’s shadow seeks to hide. We sift through dust and ancient stone, To find the secrets once unknown. Beneath the lunar, lonely crust, We stir the silent, silver dust.

🔭 Scientist spotlight

Subrahmanyan Chandrasekhar 1910–1995 · Astrophysics

An Indian-American astrophysicist, he is best known for his work on the mathematical theory of stellar structure. He discovered the 'Chandrasekhar limit,' which determines the maximum mass a white dwarf star can have before collapsing. His profound contributions to the study of black holes earned him the Nobel Prize in Physics in 1983.

🔢 Number theory fact

Perfect Numbers

A perfect number is a positive integer that is equal to the sum of its proper divisors, excluding itself. For example, 6 is a perfect number because its divisors are 1, 2, and 3, and 1 + 2 + 3 = 6. These rare numbers have fascinated mathematicians since the time of the ancient Greeks.
