John Henry Twachtman traveled and painted in France in the mid-1880s in the company of other American expatriate artists who were working in an Impressionist style. He brought his newly learned methods back to the United States and applied them to scenes of American landscapes, like this view of a pier on the Niagara River. Twachtman was a great admirer of Claude Monet, and the older French artist’s influence can be seen in Twachtman’s use of loosely brushed blues and violets to evoke the fleeting effects of light on water and the reflections of the sky and clouds above.

After the remnants of Hurricane Florence passed over New Jersey, USA last month, the Sun came out in one direction but something quite unusual appeared in the opposite direction: a hall of supernumerary rainbows. Supernumerary rainbows only form when falling water droplets are all nearly the same size and typically less than a millimeter across. Then, sunlight will not only reflect from inside the raindrops, but interfere, a wave phenomenon similar to ripples on a pond when a stone is thrown in.
