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.

    Strange behavior of thermal expansion and resistivity equations

    The equation of linear thermal expansion is l=l_0\left[1 + \alpha(t - t_0)\right] (it is similar also to the equation of resistivity, \rho=\rho_0\left[1 + \alpha(t - t_0)\right]) \alpha is a constant dependent only on the material we are speaking about. Now, let's say I have a bar 100 m long...

    How does the function f(x)=0^{-x} behave for positive and complex numbers?

    how this function f(x)= 0^{-x} should be understood? , if x is NEGATIVE, we find no problems, since 0 raised to any power is 0 but how about x being a positive real number ? , or x being a PURE COMPLEX or complex number ? could we consider a 'regularization' to this f(x) so...

    Strange thing i noticed about centroid of a cone vs triangle

    To calculate the centroid of a cone, it seems that you have to use calculus. It comes out to be h/4, where h is the height from the base of the cone. But intuitively I thought that the centroid would have been h/3 because that's a triangle's centroid, and the cone can be obtained by rotating a...
