“Let there be light”*…

 

From oil lamps to LEDs– the price of light… a larger, interactive version here.

As we switch it on, we might spare a thought for Edward Hibberd Johnson; he died on this date in 1917.  Best remembered as a business associate of Thomas Edison (Johnson was president of Edison Electric Illuminating Co., the forerunner of Con Ed, and helped found General Electric), he was an inventor in his own right.  Johnson patented a number of lighting devices, especially streetlights, but is surely best remembered as the inventor/creator of the first electric Christmas tree lights– 80 walnut-sized red, white, and blue bulbs strung together–  which he displayed in the front window of his New York City home in 1882.

“If gold rusts, what then can iron do?”*…

 

Austrian designer Klemens Schillinger has created a series of rings that are sized to show the fluctuating price of gold over the past five decades.

Assay the results here and here.

As we think twice about all that glitters, we might recall that it was on this date in 1924– four days before the publication of André Breton’s first Surrealist Manifesto— that The Bureau of Surrealist Research, AKA the Centrale Surréaliste or “Bureau of Surrealist Enquiries,” opened in Paris under the direction of Antonin Artaud.  Located at 15 Rue de Grenelle, it was home to a loosely affiliated group of Surrealist writers and artists met, held discussions, and conducted interviews in order to “gather all the information possible related to forms that might express the unconscious activity of the mind.”
