# Which road to which reality?

Hundreds of books pass through my hands in any given week in my library job.

Few of them make me stop and look.

The Road to Reality: A Complete Guide to the Laws of the Universe by Roger Penrose has a catchy title for a person like me, though. I imagined myself opening it, reading a few life-changing phrases and sighing, “So that’s what life is all about.”

Alas, I lasted only as far as the mathematical equations:

Taking the particle’s ordinary 3-velocity to be v, so that v = (dx1 / dt, dx2 /dt, dx3 / dt), where t = x0, we get [18.19],[18.20]

p = mvm = γμva = γ(c2, v),

where

γ = (1 – v2 /c2) – 1/2.

The equation road led me to the reality of a dead end.

Is the universe is only ours to appreciate if we study enough math?

I sure hope not.

I wouldn’t have wanted to see my grandmother’s magical ability with pie crust trapped in a mathematical equation. I don’t believe my friend Etienne’s off-the-charts charisma can be captured that way. Or my love for my children? There’s no equation complex enough.

I thought of The Big Bang Theory episode where the scientific geniuses rhyme off answers to complex scientific questions in the Physics Bowl. Penny sleeps through the event and average viewers like me wonder Who knows that stuff?

After the physics event Penny brings out her own trivia cards. The answers to the popular culture questions would be obvious to most of us, but Leonard says, “Who knows this stuff?”

I’ll stick to the one with apple pie and no equations.

While a Nobel prize in physics would be exciting, my reality is the same as yours. I’ll be happy with an apple pie and I won’t call it settling – it’s destiny.

Your light-hearted approach to scientific theory suits me just fine. Words resonate, numbers don’t in my world.

Is it a berry pie? Your yummy photo surely doesn’t look like apple. 🙂
