Writing with stylus and folding wax tablet. painter, Douris, ca 500 BC

The wax tablet was an important contribution to the written culture of ancient civilizations because it was the first widely used device for casual writing, intended for individuals other than scribes. Before wax tablets, anything that was written down had to be considered of great and enduring importance. But once there is writing, there arises a need for temporary writing — a quick note to jot down and throw away the next day, an aid in calculating a math problem, a rough draft of a docu­ment that would later become permanent. All the other previous writing surfaces had been, for all intents and purposes, permanent. You could not bake a clay tablet to throw away the next day, or jot down something on an expensive scroll of papyrus and throw it away. And once something is literally carved in stone, it is figuratively ‘carved in stone.’ It can’t be unwritten. The wax tablet, therefore, was the original Etch A Sketch for the ancient world…

As we rock the stylus, we might recall that it ’twas on this date in 1852 (according to the stories) that Sherlock Holmes’ sidekick, Dr. John H. Watson, was born… while Holmes did occasionally say “Elementary!” (e.g., in “The Crooked Man”), he never actually said “Elementary, my dear Watson” to Dr. Watson in any of the stories/novels by Sir Arthur Conan Doyle.  The phrase was actually a kind of homage, offered by P.G. Wodehouse, who first used it in Psmith Journalist in 1915; it found more common currency as it made it’s way into the scripts of the Sherlock Holmes films, perhaps most notably on the pursed lips of Basil Rathbone…

Ironically, it was on this date in 1930 that Arthur Conan Doyle, Holmes’ creator, died.

Seeing is… well, seeing…

Via Discover‘s Bad Astronomy blog, one of the more amazing optical illusions that your correspondent has ever seen:

Alternating red and green spirals, right?  Actually, they are exactly the same color.  As Bad Astronomy explains,

The reason they look different colors is because our brain judges the color of an object by comparing it to surrounding colors. In this case, the stripes are not continuous as they appear at first glance. The orange stripes don’t go through the “blue” spiral, and the magenta ones don’t go through the “green” one. Here’s a zoom to make this more clear:

The orange stripes go through the “green” spiral but not the “blue” one. So without us even knowing it, our brains compare that spiral to the orange stripes, forcing it to think the spiral is green. The magenta stripes make the other part of the spiral look blue, even though they are exactly the same color.

Read the full story in Bad Astronomy here.  And for a treat, visit the site of the originator of the illusion, Japanese psychologist Akiyoshi Kitaoka here.

As we reconsider the evidence of our eyes, we might recall that it ’twas on this date in 1852 (according to the stories) that Sherlock Holmes’ sidekick, Dr. John H. Watson, was born… while Holmes did occasionally say “Elementary!” (e.g., in “The Crooked Man”), he never actually said “Elementary, my dear Watson” to Dr. Watson in any of the stories/novels by Sir Arthur Conan Doyle.  The phrase was actually a kind of homage, offered by P.G.
