Irony In The Lab

Four evenings a year, the setting sun aligns perfectly with Manhattan’s street grid, creating a breathtaking wash of illumination along the cross streets, and tonight is one of them! In this video, Frederick P. Rose Hayden Planetarium Director Neil deGrasse Tyson, who first noted the phenomenon more than a decade ago and coined the term “Manhattanhenge,” explains the phenomenon.

Two jets colliding can form a chain-like fluid structure. With increasing flow rate, the rim of the chains becomes wavy and unstable, forming a fishbone structure where droplets extend outward from the fluid sheet via tiny ligaments. Eventually, the droplets break off in a pattern as beautiful as it is consistent. (Photo credits: A. Hasha and J. Bush)

Despite its appearance, there is order in the chaos of turbulence. These snapshots from a turbulent channel flow simulation outline these coherent structures in black. The top photo shows a top view looking down on the channel and the bottom image shows a side view of the channel. It is thought that studying these coherent structures may help shed light on turbulence and its formation, which remains one of the great open questions of classical physics. (Photo credit: M.

Ooh, I love fluorescent compounds! It's a great reward for the long process of synthesis.

How incredible is this compound I made??! It’s an NBD amine, which is fluorescent and used for labeling compounds for fluorescence assays.
