Ruckert, coloured tea service, 1887-96, AlamyEarly medieval Russian silver often included calm niello work and ornamental lines with black enamel. But under Tsar Peter the Great (1682-1725), who west­ernised the Russ­ian Empire, local silversm­iths began explor­ing modern forms.

$\newcommand\C{\mathbb{C}}$ I came up with the proof below while preparing a lecture for my complex analysis course. I learned from Sinan Gunturk that Peter Lax showed him the same proof back in 2007. Let \(O\subset\C\) be open and convex. Let \(z_0 \in O\) and \(c: [0,1] \rightarrow O\) be a closed piecewise \(C^1\) curve. Recall that the winding number of $c$ around $z_0$ is defined to be \[ W(c,z_0) = …

For a long time, I've been trying to learn more about my husband's 3d great-grandparents, William Tyler Bentley (1795-1873) and Olivia Morgan Bentley (1799?-1838). The earliest official document I have for this family is the 1830 US Census, where they're enumerated in the town of Sandy Creek, Oswego County, New York. Other documents confirm Oswego as the birthplace of William and Olivia's children in the 1820s and 1830s.Browsing the 1830 …

You have surely encountered them at some point in your front-end journey, and if you follow me, you also know that I use them all the time. I use them for CSS patterns, nice CSS decorations, and even CSS loaders. But even so, gradients have a tough syntax that can …
