Strange Definition and 588 Threads

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.

    Why Does Airflow Decrease When Blowing Directly Into a Pipe?

    if you use your mouth to blow air through a pipe (an A4 page rolled into a pipe for simplicity) with your mouth against the pipe, the outlet flow is much less compared to when you blow through the pipe with your mouth away from it. In terms of fluid mechanics, why does this happen?

    Strange Integral- Does it even exist?

But that can't be right because the right side kept the original expression. Some help might clear up the...

    Something strange about uniqueness of the derivative in higher dimensions

    Recall that for a function f:A\subset \mathbb{R}^n\rightarrow \mathbb{R}^m, the derivative of f at x is defined as the linear map L:R^n-->R^m such that ||f(x+h)-f(x)-L(h)||=o(||h||) if such a linear map exists. We can show that for certain geometries of the set A, when the derivative exists...
