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.

    A Strange Tetrad Form of Einstein-Hilbert Action

    I have seen it the claimed that the Einstein-Hilbert action can be written in terms of a tetrad ##e_{\mu} \, ^a## as \begin{align} S &= \int d^n x \, e R(e_{\mu} \, ^a, \omega_{\mu a} \, ^b (e)) \\ &= \int d^n x \, e (T_{ca} \, ^a T^{cb} \, _{b} - \frac{1}{2} T_{ab \ c} T^{ac \ b} -...

    I Explaining the Vertical Line Feature in Graphing Equations

    Strange unit of mass flow rate G?

    Hi When I was writting my thesis I found in an article, published in International Journal of Heat and Mass Transfer, an unit of mass flow rate G - kg/(m^2*s). Isn´t it wrong? I think that the unit of mass flow rate is kg/s. Would you mind helping me to figure it out? Thanks.

    I Is the Strange Star's Composition Similar to a Bose-Einstein Condensate?

    So at 5:20 it is explained that many of the quarks are converted to strange quarks and this is a away of going around the pauli exlusion principle inside of a quark star. So does this mean it's like a Bose Einstien Condensate? The Bose Einstein Condensate is very cold though.
