The Magnetic Motor

I should have paid more attention in my high school science classes; which is really an odd thing to say about someone who was. is, and I hope always will be curious about how “things” work.  Not just how things mechanically work, but what are the scientific principles behind why things work.  As such, when I was a kid I was absolutely fascinated with the science of “things;” yet as an adolescent I became a very lazy student, and essentially ceased trying in school – shame on me.  Well, I know I am not the only person who has ever taken an educational slumber in their teen years, and I am not the last either, but when I stumbled upon the below video about an electric car that runs on what is called a magnetic motor, and thus doesn’t need a battery, I sure do wish I could revisit the teen me and give him a kick in the pants.

Now, I want to know more about the principles of magnetism, and how those principles can be applied in energy producing applications.  Sure, as a car guy, who loves the sound emitted through the exhaust notes of powerful cars, the whine of an electric car seems anti-climatic and lame in comparison; however I am also a realist, and realize that fossil fuels are finite in their availability, and that they do emit pollutants into the atmosphere.  So, I know there will have to be a viable, efficient, and abundant alternative that takes hold at some point, and after watching the above video, as well as just doing a cursory reading up on the magnetic motor, I can’t help but wonder if it couldn’t be that viable alternative?

Sadly, the above videos don’t do a very good job of explaining exactly how either of their “miracle” engines work, let alone their viability, but you have to admit that it is intriguing, that there could be a relatively simple, inexpensive, and almost limitless source of energy already available.  Is it viable, practical, and feasible?  Well, I did essentially take my teen years off educationally, so I am no scientist, but  I’d gladly trade the sound and the fury of the internal combustion engine for the dulcet whine of electric motors, if it meant saving me a little coin along the way.  Wouldn’t you?

Science Confirms – Pop Music all Sounds the Same

I have never really been a fan of Pop music.  That isn’t to say that there has never been Pop songs that I  liked. Quite the contrary, there have been several Pop songs that I have found catchy, and enjoyable; but not nearly enough for me to go running out and buy the single, or album.  Why?  Well, at the risk of sounding completely snobish here, I find a lot to be desired in the artistic merits of most, if not all, Pop music.  Again, this isn’t to say that if one were to browse through my music library that every little piece of music there are bastions of high-brow musical masters.  Trust me there are plenty of low-brow clunkers in there.  I guess the simplest way to put my views on Pop music is that I don’t really find any real or great difference between one Pop song or another.  In short, Pop songs all, basically, sound the same to me.

Is it because I am just too old now, and thus a “square,” who just doesn’t get it?  Well, while I am old enough to be the father to many a Bieber “belieber,” and the Bieb’s himself; the fact that I have never, ever, bought, or asked my parents to buy, any Pop album, cassette, CD, MP3, or any other musical format, at any stage of my life, should debunk that belief.

Am I alone in my thinking?  Probably not; and as it turns out science has now confirmed my suspicion/belief that all Pop songs not only sound the same, but they are getting louder too.

According to an article from Reuters; researchers in Spain used what is known as the Million Song Dataset, which breaks down the audio and lyrical content of songs into data that can be put through analysis, to study Pop songs from 1955 through 2010.  The results?  Well, it does appear, after countless algorithmic analysis, that Pop songs have become louder and more musically bland “… in terms of chords, melodies, and types of sounds used.”

So, there you have it.  It is now a scientific fact that Pop music does, in fact, all sound the same . . .

Why music makes us feel good

Is music humanity’s drug of choice? What is the mysterious power behind it’s ability to captivate, stimulate and keep us coming back for more? Find out the scientific explanation of how a simple mixture of sound frequencies can affect your brain and body, and why it’s not all that different than a drug like cocaine.

Written and created by Mitchell Moffit and Gregory Brown, this video from asapSCIENCE explains the scientific connection between listening to music and dopamine, and how similar it is to certain party drugs.

Mercury + sound = awesome

This is what happens when you subject mercury to different tones of sound. This would be an example of cymatics, which is the study of visible sound and vibration. The footage above is slow-motion, and set to music.

Nick Moore, the photographer explains:

The mercury is sitting in a concave plastic lens from an old projection TV (it was convenient), the lens is stuck to a 12inch speaker using Silly Putty to stop it from rattling around or bouncing.

The tone is a pure sine from an old signal generator (1960s) I believe it was between 10Hz and 120Hz. The higher the frequency the more nodes (bumps) appear on the mercury. They are actually 3 dimensional standing waves.

Here is the original video, at full speed, with the original tones that the mercury is reacting to:
