In logic. The law of double negation.
Negation of negation gives an assertion.
Example: "If it is not true that the universe is not infinite, then it is infinite.".

Technology, algebra, logic, the meaning of life

Ask the questions that interest you, even if they seem silly, childish, strange, funny, embarrassing, uncomfortable, or abstruse.
