In mathematics the Greek letters theta ($\theta$), phi ($\phi$) and lambda ($\lambda$) are used to describe mathematical objects. They don't have a fixed meaning though. The universe of mathematical objects is too large to establish a one-to-one mapping to the Greek alphabet. Even $\pi$ doesn't always reflect the ratio of circumference and diameter of the circle, in number theory $\pi(x)$ means the number of primes less than or equal than x, in group theory $\pi(x)$ is sometimes used as a symbol for a permutation.
Did you know that the Greek letters theta ($\theta$), phi ($\phi$) and lambda ($\lambda$) have a sacred meaning in the Scientology religion? In Scientology the symbol for the life static is the Greek letter theta ($\theta$), the symbol for the physical universe ( aka MEST in Scientoloy-speak: matter, energy, space and time) is the Greek letter phi ($\phi$) and living organisms are represented by the Greek letter lambda.
- $\theta$ = Life Static;
- $\phi$ = Physical Universe or MEST;
- $\lambda$ = Living organism.
