A spring snowstorm overnight on May 8 into May 9 blanketed northern New Jersey with cold and snow, weather reports said. Parts of New York, Pennsylvania, Maryland and Delaware were also affected by the storm. The National Weather Service’s Mount Holly office recorded temperatures in the low 30s, some going below freezing into the mid-to-high 20s across the northeast. A local resident in Newton, New Jersey, filmed video of the storm blowing snow across their backyard. In the morning, the yard and garden were covered. “Snow on the ground with a pool open seems odd,” J&B Landscape wrote on one video. On another they wrote, “Nice winter morning in May.” Credit: J&B Landscape via Storyful

We study the geometry and topology of exotic Springer fibers for orbits corresponding to one-row bipartitions from an explicit, combinatorial point of view. This includes a detailed analysis of the structure of the irreducible components and their intersections as well as the construction of an explicit affine paving. Moreover, we compute the ring structure of cohomology by constructing a CW-complex homotopy equivalent to the exotic Springer fiber. This homotopy equivalent space admits an action of the type C Weyl group inducing Kato's original exotic Springer representation on cohomology. Our results are described in terms of the diagrammatics of the one-boundary Temperley-Lieb algebra (also known as the blob algebra). This provides a first step in generalizing the geometric versions of Khovanov's arc algebra to the exotic setting.

Apparatus and method for rotating an object using a music box mechanism having a spring motor. Apparatus includes a mechanical motor having a spring coupled between a body and a shaft of the music box where the shaft and the body are mounted for rotation relative to each other. The spring is windable by a user to store mechanical potential energy and when released, unwindable to release the stored energy and cause relative rotation between the body and the shaft. A base adapted for stationary placement against a surface such as a table or desktop or a wall or other stationary surface is fixedly coupled to or integrally formed with the shaft of the music box motor. An object such as a spherical planetary object or globe or any other object is connected to the body and includes an aperture or hole through which the base extends to the shaft. This aperture permits the object to rotate about the shaft without interference so that the body and the object rotate about the shaft as the spring unwinds. Connection of the winding mechanism shaft to the fixed base causes the body of the music box and attached object such as the globe to rotate.
