Formula of Love

“Love is like π – natural, irrational, and very important.” – Lisa Hoffman

Certain scientists think that love is a chemical state of mind and the formula for love is as follows:

dopamine + seratonin + oxytocin

C₈H₁₁NO₂ + C₁₀H₁₂N₂O + C₄₃H₆₆N₁₂O₁₂S₂ 

How many atoms  are there in the formula of love?

Answer

Mystic Number 7

Why we frequently use number 7?

Why there are seven days of week? seven deadly sins? seven wonders? . . . .

Why Is X The Unknown?

Terry Moore explains that the inventors of algebra were Arabic scientists. Their definition:

X = something, some undefined unknown thing = the unknown thing.

When the books were translated from Arabic to Spanish the Arabic unknown was “SH” that did not exist inSpanish. They replaced it by “X“.  It migrated to other European languages 600 years ago.

X is “X” because Spanish language does not have “SH“.
