Scientists in New Atlantis

"These are (my son) the riches of Salomon's House. "For the several employments and offices of our fellows; we have twelve that sail into foreign countries, under the names of other nations, (for our own we conceal); who bring us the books, and abstracts, and patterns of experiments of all other parts. These we call Merchants of Light. "We have three that collect the experiments which are in all books. These we call Depredators. "We have three that collect the experiments of all mechanical...

 Children's Art Has Its Own Logic

Even simple scribbles are meaningful. While it was once thought that kids only scribbled to experience the physical sensation of moving their arm along the page, “now it’s been shown that when children are scribbling … they’re representing through action, not through pictures,” said Boston College’s Winner. “For example, a child might draw a truck by making a line fast across the page and going ‘zoom, zoom,’ and so it doesn’t look like a truck when the child is done, but i...

 Why Did Everyone Draw that Fancy "S" in Grade School

"The reason kids go through this is probably because it's a Moebius strip," he said, referring to the sort of looped one-surface shapes Escher was fond of drawing. "It can't be drawn continuously, but it does have a perpetual flow." I think he was on to something. Most nine-year-olds can't draw, so when someone hands them a magical recipe to create something fairly cool, on demand—that'll go viral. Especially when the shape has the sophisticated, mathematical lineage of a Moebius strip. Y...

 Back-of-the-Envelope Calculation

It was from Kuiper that I first got a feeling for what is called a back-of-the-envelope calculation: a possible explanation to a problem occurs to you, you pull out an old envelope, appeal to your knowledge of fundamental physics, scribble a few approximate equations on the envelope, substitute in likely numerical values, and see if your answer comes anywhere near explaining your problem. If not, you look for a different explanation. It cut through nonsense like a knife through butter.
