I once had a beutiful pin of my grandfather's. It was a gold skull that said XXX across the forehead, had an emerald eye, and my grandmother's initials on the back. He was a member of Pi Kappa Alpha fraternity and graduated from the University of Missouri in 1910 or so. I suspect you have someone's fraternity pin there. Mine also had a skeletal hand up over the other (empty) eye socket.
I agree-- I don't think this is a German military pin. The SS wore a Skull insignia on their visor caps. This small pin made of stamped aluminum sometimes sale for $250.
I'm researching the same thing, my grandmother was handed down her uncle's (I think) pin fitting that EXACT description. Actually her uncle had given it to his wife, he "pinned" her, kind of signifying she was taken. My grandmother said it was from his fraternity at MCV here in Virginia which is now known as VCU, she seems to think it was a medical fraternity or something. But I'm having trouble finding anything out about it online. Has anyone found anymore about it since posting this question?
By itself, nothing: it all depends on the context. epsilon is a letter of the Greek alphabet which is used in calculus to represent a very small number.
The value of epsilon can vary depending on the context. In mathematics, epsilon is often used as a small positive quantity representing an arbitrarily small number. In science and engineering, epsilon can represent error tolerance or machine precision. It's important to specify the context in order to determine the specific value of epsilon.
The greek letter closest to representing the latin letter e is epsilon (ɛ). In math's, epsilon is mainly used to represent very small positive numbers (e.g. when working with proofs), and used as the Levi-Civita symbol (a.k.a. the permutation symbol, used in tensor calculus, sometimes uses upper epsilon E, instead of lower epsilon ɛ). It is also often used in statistics and numerical analysis to represent errors.
In mathematics (in particular calculus), an arbitrarily small positive quantity is commonly denoted ε; see (ε, δ)-definition of limitIn mathematics, Hilbert introduced epsilon terms as an extension to first order logic; see epsilon calculus.In mathematics, the Levi-Civita symbol.In mathematics, to represent the dual numbers: a + bε, with ε2 = 0 and ε ≠ 0.In mathematics, sometimes used to denote the Heaviside step function.
In physics, epsilon (ε) is commonly used to represent the permittivity of a material, which measures how much electric field can be stored in a material when a voltage is applied. It is a fundamental property of a material that affects its capacitive behavior in the presence of an electric field.
In the ancient system of Greek numbers it had the value 5. In calculus it is often used to represent very small values.

There is no star with that name. Many stars have names that start with "Epsilon", followed by the genitive of a constellation, e.g. "Epsilon Cruxis", "Epsilon Geminorum", etc. If its epsilon segin cassiopeia, it is 520L/Y(light years) away from earth.
When epsilon and epsilon not are equal, it indicates that the capacitance of the capacitor is purely due to the dielectric material between the plates, and there is no influence from the surrounding medium. This is known as the intrinsic capacitance of the dielectric material.
Epsilon Minus was created in 2000.
Lancia Epsilon was created in 1911.
The Riddles of Epsilon was created in 2005.
