- abstract algebra - $x^3 = x$ for all $x \in R$, where $R$ is a ring . . .
Lemma: If R R is a ring and a ⋅ x = 0 a ⋅ x = 0 for all x ∈ R x ∈ R, then a = 0 a = 0 Proof: Take x = 1 x = 1 Corollary: Let R R be a ring and a ∈ R a ∈ R Then a = 0 a = 0 if and only if a ⋅ x = 0 a ⋅ x = 0 for all x ∈ R x ∈ R By the corollary, it suffices to show that 6 = 0 6 = 0 in R R To that end, notice that by hypothesis 23 = 2 2 3 = 2 in R R

- Newton’s Rings: Definition, Equation, and Applications
Newton’s rings are a series of concentric circular rings consisting of bright- and dark-colored fringes When a plano-convex lens lies on top of a plane lens or glass sheet, a small layer of air is formed between the two lenses Newton’s rings are formed by the interference phenomenon when monochromatic and coherent rays of light are reflected from the top and bottom surfaces of this air
