Top 10 Inventions in the world

• Top 10 Inventions in the world
  In the five years that Popular Science has run the Invention Awards, we’ve seen a lot of remarkable things come out of people’s garages. Some are designed to treat the sick or save the planet. Others are simply fun to play with. But no matter what the purpose, the brilliance of the inventions and the dedication of the individuals behind them are always inspiring.
  

  This year’s 10 honorees carry on the tradition: a pen that can screen for prenatal diseases for less than a penny, a machine that uses a boat’s exhaust to treat onboard waste, and even a jet-propelled body board light enough to carry from your car to the water. Each of this year’s inventions takes on a different challenge—and solves it in its own ingenious way.

• The Stark Hand

  Created by Mark Stark, The Stark Hand prototype provides an ingenious, comfortable, and very inexpensive alternative to the hook his friend Dave Vogt had worn all his life. With the new hand, Dave can now catch balls and grip wine glasses.

• The BodyGuard

  David Brown designed The BodyGuard, a crime-fighting armored glove, as built-in self protection. The demo model has a camera, a wrist mounted stunner and lots of room for future improvements. The idea came to David while talking to his friend, Kevin Costner.

• The PrintBrush

  Weighing in at less than a pound, Alex Breton's PrintBrush easily fits in a laptop bag and prints on any flat surface, from wood to fabric to plastic. Alex worked on the project for 11 years, but a version with a bonus built-in camera comes out early next year.

• The Katal Landing Pad

  Aaron Coret and his friend Stephen Slen came up with the Katal Landing Pad after Aaron had a nasty snowboarding accident. The board, which was used during the 2010 Winter Olympics, provides a giant cushioned landing for snowboarders and helps make the sport safer.

• Dynamic Eye Sunglasses

  Unlike regular sunglasses, Chris Mullin's glasses block glare instantly with liquid crystal lenses that darken the most where the sun's light is the brightest. A particularly sunny commute inspired Mullin's invention.

• The Bed Bug Detective

  Built to imitate a dog's nose, the Bed Bug Detective sniffs out bedbugs quickly. Chris Goggin plans to create a model that can detect other pests, too, including mice and cockroaches.

• A Prenatal Marker to Screen for Pregnancy Complications

  Designed by a college student and his classmates, the Prenatal Screening Kit, or safety pen, helps detect complications in pregnancies at an early stage. The pen will be quite cheap, costing only a third of a cent per use, making it a perfect tool for hospitals in developing nations.

• The Zero Liquid Discharge

  

  John B. Carnett / Popular Science
  With a pleasant name for a gross procedure, the Zero Liquid Discharge, or ZLD, completely oxidizes and evaporates sewage from boats, airplanes and RVs. After flash evaporation, the waste leaves as a harmless, odorless aerosol.

• Kymera Motorized Body Board

  

  John B. Carnett / Popular Science
  The lightweight Kymera Body Board is Jason Woods's solution for a timeless problem (for lucky people): how to have fun at the lake without the hassle of lugging a boat around. The latest version of his motorized body board hits speeds of 25 mph.

The important things in life

A philosophy professor stood before his class with some items on the table in front of him. When the class began, wordlessly he picked up a very large and empty mayonnaise jar and proceeded to fill it with rocks, about 2 inches in diameter.

He then asked the students if the jar was full. They agreed that it was.

So the professor then picked up a box of pebbles and poured them into the jar. He shook the jar lightly. The pebbles, of course, rolled into the open areas between the rocks.

He then asked the students again if the jar was full. They agreed it was.

The professor picked up a box of sand and poured it into the jar. Of course, the sand filled up everything else.
He then asked once more if the jar was full. The students responded with a unanimous “Yes.”

“Now,” said the professor, “I want you to recognize that this jar represents your life. The rocks are the important things – your family, your partner, your health, your children – things that if everything else was lost and only they remained, your life would still be full.

The pebbles are the other things that matter – like your job, your house, your car.

The sand is everything else. The small stuff.”

“If you put the sand into the jar first,” he continued “there is no room for the pebbles or the rocks. The same goes for your life.

If you spend all your time and energy on the small stuff, you will never have room for the things that are important to you. Pay attention to the things that are critical to your happiness. Play with your children. Take your partner out dancing. There will always be time to go to work, clean the house, give a dinner party and fix the disposal.

Take care of the rocks first – the things that really matter. Set your priorities. The rest is just sand.”
