19th-Century Photographer Captured 5,000 Snowflakes
tcd004 writes "Wilson Bentley began photographing snowflakes in 1885, and managed to immortalize more than 5,000 crystals before his death in 1931. Now his images are widely recognized and highly sought after. At the age of 19, 'Snowflake' Bentley jury-rigged a microscope to a bulky bellows camera and took the first-ever photograph of a snowflake. Photography then, particularly microphotography, was much closer to science than art. In a 1910 article published in the journal Technical World, he wrote, 'Here is a gem bestrewn realm of nature possessing the charm of mystery, of the unknown, sure richly to reward the investigator." The video embedded at the link above touches on another long-forgotten piece of history: a sketch of the photographers who captured arial views of assemblages of tens of thousands of soldiers returning from WW-I, carefully choreographed and arranged to form a Liberty Bell, a Stature of Liberty, a US flag... as forgotten as the origin of the WW-I term razzle-dazzle.

WTF? Someone just doesn't understand what Public Domain really is.

It's not a grammar note, but this link to the human Statue of Liberty thing would've been nice to include.

For those wondering how wild colors and stripes on ships would hide them from U-Boats -- it didn't. It made it hard for the U-Boat captains to properly evaluate their targets. The colors and pattern would disrupt the length, angle, and speed clues seen though binoculars at a distance, and through the periscope when preparing to fire torpedoes.
Radar didn't exist during WWI, so U-Boats cruised on the surface with lookouts who could eyeball ships or ship smoke at 10 miles, maybe 20 on a good day. Given their 15-18 knot surface speed and 6-8 knot submerged speed, the U-Boat now had only 30 minutes or so to get into proper position ahead of the approaching ship -- about 4000-6000 yards (2-3 nautical miles) ahead and to one side of the approaching target. WWI German torpedoes could travel 6600 yards at 36 knots, for a max run time of just over 5 minutes. A target ship moving at 12 knots would move 400 yards in a minute. A 600 foot ship travels it's length in only 30 seconds. It's this tiny window that the Razzle-Dazzle would screw up. If the U-Boat captain guessed wrong on the ships movement due to painted false bow waves and extra bow/stern lines, the firing solution would be bad.
Remember that the ship view from the U-Boat was usually against cloudy skies of some sort in the North Atlantic. Add in the blue haze with distance, and the yellows, purples, and pinks start to blur into the background blue-gray sky. Now think of that sight through a wet periscope a few feet above the water, and you get the idea.
WWII had a brilliant camoufalge example in the bizarre sounding Pink Spitfires used for reconnaissance. The pink shade was selected to blend against the just-past-sunset twilight sky and clouds when those aircraft flew, and it was very effective.

It would have been nice to see how they looked.
I can see where he got confused; Galileo was in fact one of the "giants" Newton was referencing in the quote (Kepler was another). The great thing about that quote is that it's actually a stealth insult. Newton wrote it to a rival named Robert Hooke, who was somewhat, um, short. That exact wording is Newton's, and it is the best known expression of the thought, but the metaphor predates Newton considerably; the earliest known example of it was by Bernard of Chartres around 1130, and it was commonly used throughout the Middle Ages and Renaissance.
