Use The Force, Luke

Smirking Yoda - "Know something you don't I do..."

Smirking Yoda - "Know something you don't I do..."

These are probably some of the coolest things I’ve run across in a while, and they all have to do with using your mind to control things…

Now, most of us already use our mind to control things – like our arms and legs, but they’re of course connected to our brain through nerves and our spinal cord.

But, what about things that are not physically connected?  Well, this is where the cool stuff comes in…

In Rome, a group of European scientists say that they’ve successfully connected a robotic hand to a man who lost his arm.  He uses electrodes that are connected to his nervous system to enable him to move the arm using his brain.  Here’s the link to the Associated Press story…

I saw something like this on 60 Minutes a month or so ago, and they had another cool mindtrick technology that they showed off…

In that article, they showed off some technology that astrophysicist Stephen Hawking (who has ALS or Lou Gehrig’s disease) uses to communicate with the world.   A technology by scientists at Brown University called BrainGate lets a paralyzed patient focus their brain on certain letters on a computer screen.  When the letter that they are thinking of lights up, they are instructed to use their mind to say “yes, it’s lit up”.  The computer will recognize the difference in brain wave activity when the patient thinks of the letter and when the patient is not, so the computer would then be able to decide that the patient is thinking of, say, the letter “A”.

Scott Pelley of 60 Minutes was really amazed on the broadcast to see this technology in action – allowing people to use their minds to spell out words and sentences (here’s a video link to that article…)

In fact, I think that it’s so cool and important that I’ve asked my wife Stephanie to make sure that if I’m ever paralyzed that we look into using the technology.  I personally couldn’t imagine having my mind being fully active, but also being unable to communicate with anyone.  This seems like such an enabling and freeing technology that I would totally want to grab it if I could…

The last cool thing actually more a Christmas-related technology, but cool none the less.  It’s the Star Wars Force Trainer (I mean, how cool is that?!…).  With it, you put on a headset which has dry sensors that you apply to your head.  These sensors measure brain waves, such as alpha, beta, and theta waves – basically, different frequencies of brain wave patterns.  When the sensors measure certain patterns, the headset sends a wireless signal to a remote device that turns on a fan that pushes a ball up a cylinder.  The more you concentrate and give off the right brain wave signals, the higher the ball will go. 

So, you’re using your mind (or maybe it’s the Force) to push the ball up the cylinder (here’s a post on how the technology actually works…)

These technologies really make it seem like we’ll be using the Force soon, huh?  As my Smirking Yoda might say, “The Force a very powerful ally it is, mmm?”

Stephen Hawking has many things in common with some of the great scientists of our time, his understanding of the intricacies of the universe rivaling that of Albert Einstein.

When Stephen Hawking was born, he came into our world exactly 300 years after Galileo Galilei left.  Two great scientists, connected by their birthdays, separated by three centuries.

Yet, the most remarkable aspect of Stephen Hawking’s contributions to science is his ability to communicate his ideas to others, especially those outside the sciences.

And of course, this is made even more remarkable given what he has personally had to overcome.

Stephen Hawking received his Ph.D. in cosmology from Cambridge University, but almost upon arriving there, he started developing the symptoms of amyotrophic lateral sclerosis (ALS), which is also known as Lou Gehrig’s disease.  This is a type of neurological disease that causes loss of neuromuscular control and, in many cases, paralysis.

Hawking is now bound to a wheelchair, is almost entirely paralyzed, and can only speak through the aid of a computer-generated voice synthesizer.  Hawking uses his cheek to painstakingly enter words into the communications device, so constructing complete sentences is a long process.

While people who develop the stages of ALS are given about two to five years of life expectancy, Hawking has survived with the disease for well over 40 years.

Yet despite these physical challenges, he achieved great scientific success, being selected the Lucasian Professor of Mathematics at Cambridge University (the same position held by Issac Newton 300 years earlier) and being named a Fellow of the Royal Society, Britain’s oldest and most prestigious scientific association.

However, Hawking’s most indelible contribution to science would be the publication of his best-selling book A Brief History Of Time, which stayed on the British Sunday Times bestsellers list a record-breaking 237 weeks.

In his book, Hawking explains the aspects of cosmology, including black holes, the Big Bang, and superstring theory, to those not skilled in the sciences.  His entire goal for the book was to communicate his knowledge to others who didn’t have his background in physics, and probably would not understand complex mathematics by showing equation after equation after equation.

In fact, as the story goes, Hawking was warned by his editor that for every equation he included in the book, his readership would be cut in half.  For that reason, he only included Einstein’s E=mc2 relationship, and went further to make the subject accessible by including many illustrations throughout the book.

While Stephen Hawking can teach us a great deal about black holes and gravitational singularities, he teaches us much more about something else that makes him a great scientist.  The fact is that information in his mind would be useless to anyone else if he wasn’t able, somehow, to communicate it effectively.

Society progresses when the innovators and the discoverers share with others what their ideas are and what they’ve discovered.

Becoming successful in science and technology takes a desire to communicate what you know to others, so that they can share and build on these discoveries. 

The greatest impact of your work will be when more people know and rely upon your insights.  However, they won’t be able to do that unless they understand what you know.  And for them to know and to understand, you must make the choice to explain what you know and communicate your understanding effectively.

Just imagine the loss to our world had Stephen Hawking not developed his magnificent ability to communicate what he knows.  Certainly many explanations could have been given that his physical ailments have locked away his understanding and prevented the world from accessing his knowledge.

However, he chose to overcome these limitations and developed his extraordinary means of communicating his knowledge and understanding.

And the world, in fact the universe, is a better place for it.
