The hillside behind our house isn't generally much to look at, but once all the trees turn it's gorgeous.

In the height of summer it [the grasshopper warbler] chirps the whole night: its sibilous note is observed to cease about the latter end of Jul

That's the premise of the overload principle, and it must be applied, even to ab training, if you're going to develop a cut, ripped midsection.

The same holds for McDuff and Wehrheim's 'Kuranishi atlases' in arXiv:1508.01556. Using results of Yang on polyfolds and Kuranishi spaces surveyed in arXiv:1510.06849, a compact topological space X with a 'polyfold Fredholm structure' in the sense of Hofer, Wysocki and Zehnder (see e.g. arXiv:1407.3185) can be made into a Kuranishi space bf X uniquely up to equivalence in bf Kur. Our Kuranishi spaces are based on the author's theory of Derived Differential Geometry (see e.g. arXiv:1206.4207), the study of classes of derived manifolds and orbifolds that we call 'd-manifolds' and 'd-orbifolds'.
