#### Scherk meets Enneper

My little excursions into the history of minimal surfaces continues with a contribution of Heinrich Scherk from 1835. Making assumptions that allowed him to separate variables in the so far intractable minimal surface equation, he was able to come up with several quite explicit solutions, two of which are still of relevance today. 151 more words

#### Periodic k-Noids (Minimal Surfaces in the Wild II)

The k-Noids that Shireen built last winter will keep roaming the Swiss landscape, from May to August in Wülflingen. Maybe it is time to corral them. 136 more words

#### Frie Ottos Bubble Experiment 2

**Minimal Surface**

Above is a photograph of Frie Ottos work. I’ve directly copied this experiment to see for myself how the bubbles form to create the minimal surface between curves. 71 more words

#### Scherk's Minimal Surface

In mathematics, a **Scherk surface** (named after Heinrich Scherk in 1834) is an example of a minimal surface. A minimal surface is a surface that locally minimizes its area (or having a mean curvature of zero). 478 more words
