The Impossible Machine

Written by Jim Henderson

Continued from page 1

Impressed? You should be! By now you know that I canít even begin to make this machine, even with allrepparttar technology today or inrepparttar 127722 next thousand years. So Iíll confess right now that I canít make it, even if I wanted to. So it would be no way that it could just happen by accident? And I donít feel bad that I canít build it because neither can anyone else. Not even a team of scientists, engineers, and inventors.

Now let me say that I am not talking about science-fiction, I am talking about something that is very real. And itís been around for thousands of years, too. Itís not really a machine, though because no machine will ever be able to be so complex and do so many things by itself. A machine, by comparison, is a crude and stupid device. But this is real. Itís called a ďcellĒ. Your body is made up of literally billions of them, each functioning on itís own without any instruction from you. They all work together with every other cell inrepparttar 127723 body to maintain and support life. They never go to class but you will have to if you want to begin to understand what little we actually know about them.

Maybe you were not aware that a cell was so much more wonderful than any machine made by man could ever be. And more complicated, too. More than any machine that could be built.

Which brings me torepparttar 127724 question...Who did?

Monkey Ears

Written by Andrea Campbell

Continued from page 1

The constant ambient air temperature isrepparttar physical mechanism which, in random fashion, creates sound waves that resonate withinrepparttar 127721 air column leading torepparttar 127722 eardrum. It follows then, that these incoherent sound waves create a "resonant pressure" onrepparttar 127723 eardrum, similar to what it is like when you hold a seashell to your ear andrepparttar 127724 sound waves bounce around. The resonant pressure fluctuates and increasesrepparttar 127725 random firing of nerve cells inrepparttar 127726 auditory system. Transmitted fromrepparttar 127727 auditory system torepparttar 127728 brain, these random firings result in noise that masks or obscures a signal that contains speech or other useful information.

The smaller shape ofrepparttar 127729 monkeyís ears means thatrepparttar 127730 monkey is faced with a lot more "seashell-type roar" and noise than humans take in. "So thatís whatrepparttar 127731 average monkey is faced withóa lot more white noise is created inrepparttar 127732 little ear that blocksrepparttar 127733 outer ranges of sound. This also explainsrepparttar 127734 historic bank of data that indicates that monkeys hear a smaller range of sounds than humans do.

So, in essence, my little Ziggyís ears get a lot of ambient noise and those dumb looks in a chaotic setting can be written off to her diminished hearing, or, letís say her not hearing at a comfortable level. ###

Andrea Campbell isrepparttar 127735 author of Bringing Up Ziggy: What Raising A Helping Hands Monkey Taught Me About Love, Commitment, and Sacrifice. She frequently writes about monkeys, forensic science, criminal justice, writing and partiesÖ.

Andrea Campbell is the author of eight books on a variety of subjects including forensic science, criminal law, and primatology.
