Carl Sagan

For as long as I can remember, I've been searching for something, some reason why we're here.
What are we doing here? Who are we? If this is a chance to find out even just a little part of that
answer... I don't know, I think it's worth a human life. Don't you?
Ellie Arroway in "Contact" by Carl Sagan

The well-meaning contention that all ideas have equal merit seems to me
little different from the disastrous contention that no ideas have any merit.
Carl Sagan in "Broca's Brain"

Natural science and mathematics

E = mc²
Albert Einstein

G_μν=R_μν-1/2Rg_μν
Albert Einstein

F = m•dv/dt = m•a
Isaac Newton

iħ∂/∂tΨ(r,t) = ĤΨ(r,t)
Erwin Schrödinger

∇•D = ρ_ƒ     ∇•B = 0     ∇×E = -∂B/∂t     ∇×H = J_ƒ+∂D/∂t
James Clerk Maxwell / Oliver Heaviside

e^iπ = -1
Leonhard Euler

... for the sake of brevity, we will always represent this number 2.718281828459... by the letter e.
Leonhard Euler

Prime numbers below n: n/ln(n)
Carl Friedrich Gauss

Eadem mutata resurgo.
(Although transformed I will rise again in the same form.)
Jakob Bernoulli about the logarithmic spiral

If anybody says he can think about quantum physics without getting giddy
it merely shows that he hasn't understood the first thing about it.
Niels Bohr

You recognize the lion on its claw.
Said about Isaac Newton
