Agatha Christie: Necessity is Not the Mother of Invention

"I don't think necessity is the mother of invention — invention, in my opinion, arises directly from idleness, possibly also from laziness. To save oneself trouble."

Agatha Christie (1890-1976) was a prolific writer of detective and mystery novels during the 20th century. The Guinness Book of World Records cites Christie as the best-selling novelist of all time with over 2 billion copies sold. Her play The Mousetrap also holds the record for the longest-running production of all time; it opened in London's West End in 1952 and is still playing today after over 25,000 performances.

3D printing might save your life one day. It's transforming medicine and health care.

What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.

  • Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
  • Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
  • Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.

  • In some fundamental ways, humans haven't changed all that much since the days when we were sitting around communal fires, telling tales.
  • Although we don't always recognize them as such, stories, symbols, and rituals still have tremendous, primal power to move us and shape our lives.
  • This is no less true in the workplace than it is in our personal lives.

Has a black hole made of sound confirmed Hawking radiation?

One of Stephen Hawking's predictions seems to have been borne out in a man-made "black hole".

Surprising Science
  • Stephen Hawking predicted virtual particles splitting in two from the gravitational pull of black holes.
  • Black holes, he also said, would eventually evaporate due to the absorption of negatively charged virtual particles.
  • A scientist has built a black hole analogue based on sound instead of light.

  • The word "creative" is sometimes waved around like a badge of honor. We speak of creativity in hushed tones, as the special province of the "talented". In reality, the creative process is messy, open, and vulnerable.
  • For this reason, creativity is often at its best in a group setting like brainstorming. But in order to work, the group creative process needs to be led by someone who understands it.
  • This sense of deep trust—that no idea is too silly, that every creative impulse is worth voicing and considering—is essential to producing great work.
