Our Modern Technology

Here is something I think you will find of interest. Have you ever thought about just how much technology has advanced in the last 50 years or so. Or how some early TV programs and movies had inventions in common place use that seemed to be totally beyond the imagination.
Well, now some of those seemingly beyond belief items are common place in our every day life. Surprising?

10 Comparisons Between The Jetsons and Modern Technology

 

For those of us who grew up watching The Jetsons back in the 60′s – and to a lesser extent, the generation who were introduced to the space-age animated sitcom during its second run in the 80′s – there was a starry-eyed wonderment at what the future truly held for us. Set in the mid-21st century, The  Jetsons cartoon boasted a bevy of technological marvels. So now that we’re well into the new millennium, how are things stacking up for us? Let’s have a look at 10 comparisons between “then” and now:
  1. Flying Cars – This is probably the most popular of all the tech innovations that the Jetsons cartoon featured. While we’re not exactly zipping along on aerial freeways just yet, there are some prototypes out there to keep the dream alive.
  2. Robot Vacuum Cleaner – Here’s one technology from the ‘toon that I think we can say we’ve pretty much nailed. Thanks to iRobot’s Roomba, we are so there.
  3. Moving Walkways – Though not quite as ubiquitous as on the cartoon series, we’re enjoying  nice leisurely “strolls” on these conveyors here and there.
  4. Tanning Beds – Who knew there would be a market for (literally) self-baking ovens? Answer: Hanna-Barbera, that’s who.
  5. Televiewer – This is another tech marvel from the circa 2062 Jetson Age that has not only arrived, but thrived. We’ve raised a generation at this point that has never known a time when we didn’t get our information from a computer screen.
  6. Jetpacks – While they’re seldom seen outside of James Bond movies or sports stadiums, we’ve got the technology to jet around the skies, just like Elroy here.
  7. Talking Alarm Clocks – You can argue whether this technology is in fact a welcome advancement, but it’s here nonetheless.
  8. Video Chat – I’ll be honest. I thought we’d see flying cars before this innovation would ever come to pass. Shows how much I know. So I’m just as surprised as this guy.
  9. Push-Button Desk Job – Yep, Old George had it pretty easy at work, considering he worked a 9-hour work week. The difference now is that technology, rather than giving us more leisure time, has raised the stakes for productivity in a 40-hour+ work week. Sadly, neither Hanna nor Barbera saw that unfortunate twist coming.
  10. Automatic Meals – It may not be automatic in the strictest sense, but with the push of a button we can conjure up a meal from a frozen block of barely identifiable substances. That’s pretty cool … even edible at times.

Amazing Hair Facts!

  • Hair is the fastest growing tissue in the body, second only to bone marrow.
  • 35 meters of hair fibre is produced every day on the average adult scalp.
  • The average scalp has 100,000 hairs. Redheads have the least at 80,000; brown and black haired persons have about 100,000; and blondes have the most at 120,000.
  • 90% of scalp hairs are growing and 10% are resting.
  • It is normal to lose 100 hairs per day from the scalp.
  • You must lose over 50% of your scalp hairs before it is apparent to anyone.
  • Many drugs can cause hair loss.
  • Thyroid imbalance and iron deficiency are reversible causes for hair loss.
  • Over 50% of men by age 50 have male pattern hair loss.
  • Forty percent of women by the time they reach menopause will have female pattern (hereditary) hair loss.

Space Quick Facts



1. Saturn’s rings are made up of particles of ice, dust and rock. Some particles are as small as grains of sand while others are much larger than skyscrapers.
2. Jupiter is larger than 1,000 Earths.
3. The Great Red Spot on Jupiter is a hurricane-like storm system that was first detected in the early 1600′s.
4. Comet Hale-Bopp is putting out approximately 250 tons of gas and dust per second. This is about 50 times more than most comets produce.
5. The Sun looks 1600 times fainter from Pluto than it does from the Earth.
6. There is a supermassive black hole right in the middle of the Milky Way galaxy that is 4 million times the mass of the Sun.
7. Halley’s Comet appears about every 76 years.
8. The orbits of most asteroids lie partially between the orbits of Mars and Jupiter.
9. Asteroids and comets are believed to be ancient remnants of the formation of our Solar System (More than 4 billion years ago!).
10. Comets are bodies of ice, rock and organic compounds that can be several miles in diameter.
11. The most dangerous asteroids, those capable of causing major regional or global disasters, usually impact the Earth only once every 100,000 years on average.
