Interesting Videos on Mechanisms

I'm not super interested in mechanical solutions to problems, but I found these two videos fascinating.

Differential Gears


Continuously Variable Transmission


It's available for bicycles. Read this entertaining Review:

Thanks to my man Daniel Thompson for pointing me to the transmission links.

Too Much Caution in Science

From Wolfgang Köhler, one of the founders of gestalt psychology, speaking
in 1959:

I doubt whether it is advisable to regard caution and a critical spirit
as the virtues of a scientist, as though little else counted. They are
necessary in research, just as the brakes in our cars must be kept in order and
their windshields clean. But it is not because of the brakes or of the
windshields that we drive. Similarly, caution and a critical spirit are like
tools. They ought to be kept ready during a scientific enterprise; however, the
main business of a science is gaining more and more new knowledge. I wonder why
great men in physics do not call caution and a critical spirit the most
important characteristics of their behavior. They seem to regard the testing of
brakes and the cleaning of windshields as mere precautions, but to look forward
to the next trip as the business for which they have cars. Why is it only in
psychology that we hear the slightly discouraging story of mere caution over
and over again? Why are just psychologists so inclined to greet the
announcement of a new fact (or a new working hypothesis) almost with scorn?
This is caution that has gone sour and has almost become negativism -- which,
of course, is no less an emotional attitude than is enthusiasm. The enthusiasm
of the early Gestalt psychologists was a virtue, because it led to new
observations.

He goes on to say,
"Too many young psychologists, it seems to me, either work only against
something done by others or merely vary slightly what others have done
before; in other words, preoccupation with method may tend to limit the
range of our research."


Thanks to my man Daniel Saunders for pointing this passage out to me.

How walkable is your city?

An interesting web site that calculates a 'walk score' for any address or neighborhood:

http://www.walkscore.com/

Here are the possible scores:

Walk Score Description
90–100 Walker's Paradise — Daily errands do not require a car.
70–89 Very Walkable — Most errands can be accomplished on foot.
50–69 Somewhat Walkable — Some amenities within walking distance
25–49 Car-Dependent — A few amenities within walking distance.
0–24 Car-Dependent — Almost all errands require a car.

Beat Boxing

Beatboxing is making drum sounds with your mouth. It was never a huge part of hip hop, but was sort of big in the '80s (The Fat Boys, Doug E. Fresh, Biz Markie).

Here is Doug E. Fresh in 1986: http://www.youtube.com/watch?v=2ARBgBeHY1w
go to 0:59

It went out of style for a long time, but then some new people came along who took it even further.
Rahzel was a part of the act "The Roots." He innovated by incorporating the sounds of turntablism into the beatboxing.

Kenny Mohammad is known for the "wind technique," which involved simultaneous audible breathing while making beats with the mouth.

Two nights ago my man Jesse Stewart told me about Beardyman, and I'm very impressed.
He's incorporating technology and singing

Someone I don't hear associated with beatboxing much is Bobby McFerrin (of "Don't Worry, Be Happy" fame). Unlike the others, who focus on beats, McFerrin tries to make whole songs, including instruments, voice, and percussion, using beatboxing, singing, and percussion on his own body.

I don't think it's widely known that Michael Jackson could beatbox competently too:

Here's a guy who beatboxes while playing the flute: http://www.youtube.com/watch?v=59ZX5qdIEB0&feature=related

If you're interested in beatboxing, there are how-to videos on youtube.

OK Go video

Neat video. Good use of graphics. Also, by my count the track has 5 or 10 beats per measure. Very rare.

Funny Rap Parody (?)



Not sure if it's a parody or not, but I found it funny.

Innovative Calligraphy: Denis Brown and Calligraffiti

I just love calligraphy.  Here is some beautiful innovation.You can see the stuff I do on flickr.

There's something new I learned about: Calligraffiti. It's just what it sounds like.

Here's a great video of it in action. Very inspiring. 


Denis Brown is a master calligrapher who has done some very cool innovations-- one of which is the filming of ink falling in water. Watch this meditative, relaxing, gorgeous video:


You can see his more traditional stuff in action here:

AI and our Traditional Categories

Here's another great quote from Moravec (1999, p111).

...the idea of machinery with a conscious mental inner life frightens or enrages some people--an understandable visceral reaction, as the concept clashes with a deep primordial view of the nature of things. Similar vehemence greeted predictions of space travel early in the twentieth century. Space travel violated the self-evident dichotomy of the terrestrial and the celestial, a sacred distinction in most religions, whose abrogation, if possible at all, would surely upset the natural order, with horrible consequences. Thoughtful machinery violates the equally obvious and sacred dichotomy of the living and the dead, a difference embedded in our mentality. The skills for interacting with living things, with feelings, memories, and intentions, ar e utterly different from the techniques for shaping insensitive dead matter.
Although animate machines have existed for several centuries, they have acted more like inanimate things, with no awareness of past or future, responding to the skill but not the character of their handlers. But past machines were simpler than bacteria, and are as misleading a guide to future robot mentality as bacteria are to human psychology. Ancient thinkers theorized that the animating principle that separated the living from the dead was a special kind of substance, a spirit. In the last century biology, mathematics, and related sciences have gathered powerful evidence that the animating principle is not a substance, but a very particular, very complex organization. Such organization was once found only in biological matter, but is now slowly appearing in our most complex machines. In the old metaphor, we are in the process of inspiriting the dead matter around us. It will soon be our honor to welcome some of it to the land of the living, however upsetting that may be to our traditional categories.

Machines break down?

Here is a great quote from Hans Moravec (1999, p2):


"Things tossed up come down" is an early theory of gravity, demonstrably true in everyday life, unquestioned for millennia, until Newton developed a new theory of gravity that gave stable orbits to sufficiently fast satellites, and let slightly faster projectiles escape to infinity. "Wood rubbed warm cools down" may have been a truism for our distant ancestors, until one of them rubbed hard enough to achieve ignition temperature, whereupon the wood flamed hotter than ever on its own. "Machines break down" is a demonstrable truth of industrial society, but as machines increasingly design, diagnose, and repair themselves, it too will be suddenly invalidated. Once given "escape velocity," machines more capable than any we know will, without further help from us, grow more capable still, learning from the world, as we did in our biological and cultural evolution. The wood is already smoldering.
