Einstein’s Secret to Amazing Problem Solving (and 10 Specific Ways You Can Use It)

Einstein's Secret to Jaw-Dropping Problem Solving

Einstein is quoted as having said that if he had one hour to save the world he would spend fifty-five minutes defining the problem and only five minutes finding the solution.

This quote does illustrate an important point: before jumping right into solving a problem, we should step back and invest time and effort to improve our understanding of it. Here are 10 strategies you can use to see problems from many different perspectives and master what is the most important step in problem solving: clearly defining the problem in the first place!

 

The Problem Is To Know What the Problem Is

The definition of the problem will be the focal point of all your problem-solving efforts. As such, it makes sense to devote as much attention and dedication to problem definition as possible. What usually happens is that as soon as we have a problem to work on we’re so eager to get to solutions that we neglect spending any time refining it.

What most of us don’t realize — and what supposedly Einstein might have been alluding to — is that the quality of the solutions we come up with will be in direct proportion to the quality of the description of the problem we’re trying to solve. Not only will your solutions be more abundant and of higher quality, but they’ll be achieved much, much more easily. Most importantly, you’ll have the confidence to be tackling a worthwhile problem.

13 things that don’t make sense

A mind-spinning article from the New Scientist.

If you travel out to the far edge of the solar system, into the frigid wastes beyond Pluto, you’ll see something strange. Suddenly, after passing through the Kuiper belt, a region of space teeming with icy rocks, there’s nothing.

Astronomers call this boundary the Kuiper cliff, because the density of space rocks drops off so steeply. What caused it? The only answer seems to be a 10th planet. We’re not talking about Quaoar or Sedna: this is a massive object, as big as Earth or Mars, that has swept the area clean of debris.

Researchers detail how a distant black hole devoured a star

NASA’s Swift satellite first alerted astronomers to intense and unusual high-energy flares from the new source in the constellation Draco…

Astronomers soon realized the source, known as Swift J1644+57, was the result of a truly extraordinary event — the awakening of a distant galaxy’s dormant black hole as it shredded and consumed a star. The galaxy is so far away, it took the light from the event approximately 3.9 billion years to reach Earth.
