What is Strange: Definition and 587 Discussions

Baron Strange is a title that has been created several times in the Peerage of England. Two creations, one in 1295 and another in 1326, had only one holder each, upon the death of whom they became extinct. Two of the creations, that of 1299 and that of 1628, are extant. All four baronies of Strange have been created by writ, which means that they can pass through both male and female lines.
Following the passing of the Peerage Act 1963, Elizabeth Frances Philipps, 14th Baroness Strange of the 1299 creation, became the first woman to take her seat in the House of Lords by virtue of an hereditary peerage.

    Curved sketching strange things happen

    I was told to sketch this graph: y=\frac{x-1}{x^2-100} when x=0,y=.01 y=\frac{\frac{1}{x}-\frac{1}{x^2}}{1-\frac{100}{x^2}} as x \rightarrow \infty;y \rightarrow 0 \Rightarrow y=0 (i.e. x-axis is a horizontal asymptote to the curve) BUT when y=0; x-1=0 so that x=1. So a point...

    What causes a solution to be dependent on a parameter in differential equations?

    I'm not sure where to put this but I though DEQ would be a good start. I have been dealing with the following differential equations: \frac{d \mathbf{m_1}}{dt} = \gamma_1 \mathbf{m_1} \times \mathbf{B} - \frac{n_{2}}{\gamma_{cr}} \mathbf{m_1} + \frac{n_1}{\gamma_{cr}} \mathbf{m_2}...

    Algebraic Manipulation of Euler's Identity Leads to a Strange Result

    I was playing around with Euler's identity the other day. I came across something that seems contradictory to everything else I know, but I can't really explain it. I started with e^{i\pi} = -1. I rewrote this as ln[-1] = i\pi Multiplying by a constant, we have kln[-1] = ki\pi...
