First idea: What's important isn't the idea, its conveying the idea, articulating the idea, getting it into other people's minds and spirits, selling the idea.  The first move in any collective endeavor, and every endeavor worth its salt is collective, is selling the idea.  Not really having the idea, since they are a dime a dozen.  They're like opinions.  But getting other people sold on the idea, enthusiastic about it, on fire about it, willing to devote their time to it (or to you), that's the first real task.  So this shouldn' be called "create an idea" it should be called "share an idea" (for the touchy feely types) or "pitch an idea" (for the pragmatic business types) since that's the first real challenge and the first step in doing something in the world.

Surprising Science
  • Australian scientists found that bodies kept moving for 17 months after being pronounced dead.
  • Researchers used photography capture technology in 30-minute intervals every day to capture the movement.
  • This study could help better identify time of death.

The distances between the stars are so vast that they can make your brain melt. Take for example the Voyager 1 probe, which has been traveling at 35,000 miles per hour for more than 40 years and was the first human object to cross into interstellar space. That sounds wonderful except, at its current speed, it will still take another 40,000 years to cross the typical distance between stars.

Worse still, if you are thinking about interstellar travel, nature provides a hard limit on acceleration and speed. As Einstein showed, it's impossible to accelerate any massive object beyond the speed of light. Since the galaxy is more than 100,000 light-years across, if you are traveling at less than light speed, then most interstellar distances would take more than a human lifetime to cross. If the known laws of physics hold, then it seems a galaxy-spanning human civilization is impossible.

Unless of course you can build a warp drive.

Just when the Middle Ages couldn’t get worse, everyone had bunions

The Black Death wasn't the only plague in the 1300s.

  • In a unique study, researchers have determined how many people in medieval England had bunions
  • A fashion trend towards pointed toe shoes made the affliction common.
  • Even monks got in on the trend, much to their discomfort later in life.
