I know that today is an important day, but I can't remember why... All I have in my possession is this formula I wrote last night in my drunken stupor:
You go here:
$$B = 25 + \biggl(\frac{O}{C}\biggr)^3 + E * \sin{\sqrt{L}}$$
When names are nouns, variables are?
One, one, two, fives two far.
Two for you, one less for me.
History net, keeps us free.
Round up.
Some.
$$@1900$$
Can you help me please?
Hints
Each day I will clarify one of the variables (apart from $B$), but after that you're on your own!
