“Frida Kahlo: Art, Garden, Life”
The New York Botanical Garden, 2900 Southern Blvd., Bronx, NY
first solo presentation of Kahlo’s work in New York City in more than 25 years, and the first exhibition to focus exclusively on Kahlo’s intense interest in the botanical world. Featuring more than a dozen original Kahlo paintings and works on paper, this six-month engagement also reimagines the iconic artist’s famed garden and studio at the Casa Azul, her lifelong home in Mexico City.

[VIDEO] The Fluid Dynamics of ‘The Starry Night’: How Van Gogh’s Masterpiece Explains the Scientific Mysteries of Movement and LightPosted: January 13, 2015

…more than a masterwork of art, Van Gogh’s painting turns out to hold astounding clues to understanding some of the most mysterious workings of science.
This fascinating short animation from TED-Ed and Natalya St. Clair, author of The Art of Mental Calculation, explores how “The Starry Night” sheds light on the concept of turbulent flow in fluid dynamics, one of the most complex ideas to explain mathematically and among the hardest for the human mind to grasp. From why the brain’s perception of light and motion makes us see Impressionist works as flickering, to how a Russian mathematician’s theory explains Jupiter’s bright red spot, to what the Hubble Space Telescope has to do with Van Gogh’s psychotic episodes, this mind-bending tour de force ties art, science, and mental health together through the astonishing interplay between physical and psychic turbulence.
Van Gogh and other Impressionists represented light in a different way than their predecessors, seeming to capture its motion, for instance, across sun-dappled waters, or here in star light that twinkles and melts through milky waves of blue night sky.
“The effect is caused by luminance, the intensity of the light in the colors on the canvas. The more primitive part of our visual cortex — which sees light contrast and motion, but not color — will blend two differently colored areas together if they have the same luminance. But our brains primate subdivision will see the contrasting colors without blending. With these two interpretations happening at once, the light in many Impressionist works seems to pulse, flicker and radiate oddly.”
That’s how this and other Impressionist works use quickly executed prominent brushstrokes to capture something strikingly real about how light moves.
Sixty years later, Russian mathematician Andrey Kolmogorov furthered our mathematical understanding of turbulence when he proposed that energy in a turbulent fluid at length R varies in proportion to the five-thirds power of R. Experimental measurements show Kolmogorov was remarkably close to the way turbulent flow works, although a complete description of turbulence remains one of the unsolved problems in physics.
