# My drunken formula?

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.

$$@1900$$

Each day I will clarify one of the variables (apart from $$B$$), but after that you're on your own!
