Fixies are Impractical, Perverse Throwbacks



Specialized Globe Roll 2, in Fjord Blue

The Specialized Globe Roll 2 is a fixie. But to its manufacturer's credit, it comes with a flip-flop hub and front and rear handbrakes, allowing quick conversion to a single-speed. This makes the Roll 2 a far more versatile and sensible machine, rather than the cyclist's equivalent of a hairshirt. A beautiful piece of industrial design. MSRP US$830


Trek Soho S, in Matte Black

The Trek Soho S is also a fixie. But its manufacturer was also smart enough to give it a flip-flop hub and front and rear handbrakes, making it convertible to a single-speed. Another beautiful piece of industrial design. MSRP US$550

Fixies are Impractical, Perverse Throwbacks
by Bevin Chu
January 4, 2010


Much of what I have to say about "fixies," i.e., bicycles without freewheel mechanisms, is nicely summed up in Washington Post Staff Writer David Montgomery's widely read article, "Look Ma, No Brakes." As Montgomery puts it,

"A fixie has one speed, which makes it difficult to pedal uphill. A classic fixie has no brakes, which makes it difficult to slow on the downhill. A fixie has no freewheel, the part that makes coasting possible. Instead, the chain directly drives the rotation of the rear wheel, which means the pedals always turn while the bike moves... fixies are impractical, perverse throwbacks... "

Yes, I have heard the various and sundry "compelling reasons" to ride a fixie.

But most of their "compelling reasons" to ride a fixie are transparent rationalizations that even the fixie fanatics themselves don't believe.

One fixie guru whose authority is widely invoked by fixie fanatics, offers the following "compelling reasons" to ride fixies instead of single-speed or geared bikes.

Reason One: "Riding a fixed gear on the road is excellent exercise. When you need to climb, you don't need to think about when to change gears, because you don't have that option. Instead, you know that you must just stand up and pedal, even though the gear is too high for maximum climbing efficiency. This makes you stronger."

Reason Two: "A fixed-gear bike is considerably lighter than a multi-speed bike of comparable quality, due to the abscence [sic] of the rear brake, derailers [sic], shift levers, and extra sprockets. A fixed-gear bike also has a substantially shorter chain. A properly set-up fixed gear has a perfectly straight chainline. This, plus the abscence [sic] of derailer [sic] pulleys, makes a real improvement in the drive-train efficiency, an improvement you can feel."

Did you get that?

In one paragraph the fixie guru argues that fixies are better because forcing you to pedal against a heavier resistance "makes you stronger."

In a subsequent paragraph he argues that fixies are better because allowing you to pedal against a lighter resistance constitutes "an improvement you can feel."

The fixie guru was clearly not motivated by the reasons he offered. How could he be, when one reason flatly contradicts the other?

No, the real reason most, albeit not all fixie riders are so zealous in their advocacy of fixies, is desperate one-upsmanship. "Hipper than thou" one-upsmanship. "Greener than thou" one-upsmanship. "Que es mas macho?" one-upsmanship. "My hairshirt is scratchier than yours" one-upsmanship. All varieties of one-upsmanship, ad infinitum, ad nauseum.

For most, albeit not all fixie riders, a fixie is a status symbol, a fashion statement, a Project Runway design accessory, a means of posturing.

Compelling Reasons to Ride a Fixie

So are there no compelling reasons whatsoever to ride a fixie?

Actually, there are one or two perfectly good reasons to ride a fixie. Some road racers for example, believe that riding a fixie will help them smooth out their pedal stroke, making them more competitive during road races. For them a fixie is a special purpose training machine.













Other cyclists may simply want an "open air exercise bicycle." For them riding a fixie is akin to "spinning," only outdoors, in the fresh air, instead of inside a smelly gym or stuffy health club.















Bicycles are Replacements for Horses

Bicycles are fundamentally replacements for horses. As historian David Herlihy notes in his book "Bicycle: The History,"

"The bicycle was the culmination of a long quest for a mechanical horse – a human-powered machine that could replace the onerous burden of using horses for transportation... the quest for the mechanical horse was meant to supplant the animal’s transportation services... the bicycle was originally designed to function as a means of utilitarian transportation."
















As Eric Enders notes in his article "Your Times Is Over: Butch Cassidy and the Passing of the Outlaw West,"

Screenwriter William Goldman, like so many others, saw Butch and Sundance as emblems of a bygone era. Throughout the film [Butch Cassidy and the Sundance Kid], images of the horse and bicycle are used to contrast the 19th and 20th centuries, respectively. Eventually Butch himself realizes that his way of life is dying, and as he leaves for South America, he throws his bike down in disgust and offers a parting shot: “The future’s all yours, you lousy bicycle!”

In one scene, an opportunistic bicycle salesman interrupts a town marshal who is attempting to raise a posse, in order to peddle his newfangled contraption.

Marshal: Well, whaddaya say?

Bicycle Salesman: (He moves up next to the Marshal) I say this, I say ladies and gentlemen, boys and girls, friends and enemies, meet the future.

Crowd member: The future what?

Salesman: The future mode of transportation for this weary Western world. Now I'm not gonna make a lot of extravagant claims for this little machine. Sure, it'll change your whole life for the better, but that's all.

Marshal: And just what in the hell do ya think you're doing?

Salesman: Well, you got the crowd together. That's half my job, so I just thought I'd do a little selling.

Marshal: Well, I'm trying to raise a posse here if you don't mind?

Salesman: I got a short presentation. (To the crowd) The Horse Is Dead. You'll see - this item sells itself.

The Tie Ma, or "Iron Horse"

Nine out of ten bikes sold in America are made in China. In China, the term "iron horse" refers not to a steam locomotive, but to a bicycle. In China, a bicycle is colloquially referred to as a 鐵馬 (tie ma), which literally translates as "iron horse."


























Bicycles are Human Powered Vehicles

Bicycles are fundamentally "human powered vehicles" intended to get a person from Point A to Point B, as swiftly as possible, and as efficiently as possible.

Any energy consumed overcoming inherent mechanical disadvantages within the bicycle itself, stands in the way of the rider from getting from Point A to Point B as swiftly as possible, and as efficiently as possible.

The Freewheel or Freehub, a Gift from God

That is why the bicycle freewheel or freehub was a gift from God. The bicycle freewheel or freehub allows a cyclist to coast whenever he has built up sufficient momentum by pedaling, or whenever he is traveling downhill. Why would anyone deliberately deny himself this energy conserving mechanical advantage? To dismiss coasting as "laziness" is nonsense. The energy conserved can be used to travel either faster or longer, and usually is.

















That is why the derailleur gear was also a gift from God.















Bicycles are Fundamentally a Means of Transportation

Bicycles are fundamentally a means of transportation, intended to get a person from Point A to Point B, as swiftly as possible, and as efficiently as possible.

That was the bicycle's genesis. That is the bicycle's raison d'etre. And that is my basis for evaluating bicycle design.

That is why other than as some sort of special purpose training machine, or "open air exercise bicycle," I simply do not buy the countless "compelling reasons" to ride a fixie.

An Ordinary Urban Commuter

I like a nice road bike as much as the next person. I have owned three in my lifetime, including a Peugeot and a Pinarello.

But bicycles do not always need to be fancy. Sometimes an ordinary urban commuter is all one really needs.

Millions of ordinary urban commuters such as the one above can be found on city streets on Taiwan.

The bicycle that is, not the rider.

How to Install Windows Movie Maker 6.1 from Vista (WMM6) in Windows 7



How to Install Windows Movie Maker 6.1 from Vista (WMM6) in Windows 7
by Bevin Chu
December 17, 2009


Do you have Windows 7? So do I.

Don't you just love it? It's so much better than Vista isn't it?

There's only one problem. Windows 7 includes Windows Live Movie Maker, or WLMM, the worst version of Windows Movie Maker ever offered. WLMM doesn't even feature a timeline, the most attractive feature of Windows Movie Maker.

Vista, on the other hand, includes Windows Movie Maker 6.1, or WMM6, the best version of Windows Movie Maker ever offered.

Is there some way to have the best of both worlds? Is there some way to install the Windows 7 Operating System, and also have Windows Movie Maker 6.1, from Vista?

Microsoft will tell you you can't. Microsoft will urge you to live with Windows Live Movie Maker (WLMM), which comes with Windows 7. Windows Live Movie Maker. What a misnomer. Windows Dead Movie Maker is more like it. Windows Dead On Arrival Movie Maker, in fact. Call it WDOAMM.

Others may helpfully suggest that you download and install Windows Movie Maker 2.6 (WMM2.6). WMM2.6 isn't as bad as WLMM, but it's nowhere as good as WMM6.

Don't listen to them. Both WLMM and WMM2.6 are inferior versions of Windows Movie Maker with fewer features.

The fact is, you can install Windows Movie Maker 6.1 in Windows 7.

Simply visit one of a number of sites that offer free downloads of WMM6 specially tweaked so that it can be installed in Windows 7. Several are listed below.

They appear to have been written by the same software programmer, one Noel Danjou, to whom we owe a debt of gratitude.

Download the executable, install it, and you're good to go!

NB: I'm not sure whether WMM6 should be referred to as 6.0 or 6.1. I'm calling it 6.1 in the interim.

Windows 7 Beta Fish Wallpaper










 

This wallpaper is beautiful. That much is obvious.

But why did I say it was clever? Because experience shows that blue may well be the most durable color for a wallpaper. Many other colors become tiresome after a while. Blue on the other hand, seems to hold up in the long term.

Given blue as our first choice, what next? One could of course make the blue wallpaper a blue sky. After all, the name of the operating system is Windows. As one looks out one's window, what does one see? The blue sky, of course.

But another, less obvious, but even more ingenious concept, is to make the blue wallpaper the blue sea. The bright spot is of course the sun. Its rays penetrate the surface of the waves.

Giant CT 102 Urban Commuter Bicycle

Giant CT 102 Urban Commuter Bike

捷安特 CT 102 城市通勤車 / Giant CT 102 Urban Commuter Bike, 2008 Model

Technical Specifications :
http://www.giant-bicycles.com/zh-TW/bikes/lifestyle/2224/31946/

My new bicycle. I just bought it today. A Plain Jane urban commuter bike. Nothing fancy, but solidly built by Giant, Taiwan's premier bicycle manufacturer. Carbon steel frame. 18 speed Shimano derailleurs. Shimano brakes.

This is not a high performance bike. High performance bikes don't come with full fenders, front brackets for mounting shopping baskets, rear luggage racks, and kick stands.

Price? Under $4000NT. About US$130.

When I was living in LA during the 1980s I had a Pinarello racing bike. Italian import. Double-butted aluminum frame. 10 speed Campagnolo derailleurs. Campagnolo brakes. Sew up tires. Total weight 22 lbs. I could hold it up with one finger on one hand.

Price? US$800 in 1980 dollars. Money well spent. No regrets. It was what I wanted. It was what I got.

But that was then, this is now.

Now all I want is a dependable urban commuter bike. Something to get me to the office for work. Something to get me to the supermarket for a bottle of orange juice. Something that can withstand the punishment dished out by the badly paved roads here on Taiwan.

I went online to get a feeling for what was available at what price. Given my modest requirements, I decided this particular make and model was the one to get.

Could I have afforded a fancier bike?

Of course. But I didn't want a fancier bike. I would be too nervous leaving a fancier bike out on the sidewalk. Anything fancier would be far too likely to get stolen. It simply wouldn't be worth the aggravation.

In fact, I considered getting an even cheaper bike for just that reason.

The "big box" discount stores on Taiwan, such as Carrefours, Geant, and RT Mart, sell no name bikes for under $2000NT. About US$65. I looked them over. Let me tell you, when you go from $4000NT to $2000NT, the quality takes a big hit.

An even more serious problem with these $2000NT no name, discount store bikes, is that the frames are too small. I'm 6'-2" (187cm), and these small framed bikes simply won't allow me to position myself on the seat properly.

So in the end I settled for an entry level name brand bike by Giant.

Some friends suggested a folding bike, something I could take indoors with me so it wouldn't be stolen.

But given the size of the potholes on Taiwan, I really feel more confident riding a bike with large diameter, standard sized wheels, rather than the tiny wheels found on folding bikes.

With the tiny wheels, one gets the queasy feeling the front wheel could drop into a pothole. The bike would then stop dead, and one would go flying over the handlebars.

The amazing Golden Ratio

The amazing Golden Ratio
Assem Deif
Al-Ahram Weekly
27 September - 3 October 2007

Issue No. 864

Heritage


Artists reckon that the "Golden Ratio", also called the "Golden Section Phi" and nature's most astonishing number, is the ratio that controls the proportions of all beautiful objects, writes Assem Deif*

Historians trace the Golden Ratio back to Euclid, yet even before him it was governing the dimensions of monuments in ancient Egypt. The most pronounced of these is the Great Pyramid. The Great Pyramid is not the only structure from ancient Egypt that complies with constants like Pi or Phi; the Egyptians used the Golden Ratio in many ways both in the architecture of their temples and in their drawings. So whereas, the discovery of the "golden rule" was generally credited to the Greeks, the findings of such Egyptologists as De Lubicz and Fliders Petrie produced irrefutable proof that the Egyptians had a mathematical understanding of these constants, the ratios, not the symbol, 1000 years earlier.

There was much cross-culture between the Egyptian and Greek civilisations during the Hellenistic era, particularly in Alexandria where Egyptian and Greek scientists studied together at the Mouseion. Among them was Euclid. Historians call him Euclid of Alexandria without precluding the possibility he might have been Egyptian. It was in Alexandria that Euclid wrote The Elements.

Greek scholars were visiting Egypt even before the Mouseion was founded, including Thales, Socrates, Plato and Aristotle, and Pythagoras, who spent 22 years in Egypt and announced his theory only after leaving. Egyptians were aware of the triangle 3:4:5 which Pythagoras himself called the "Holy Triangle". Eight pyramids from the fourth and fifth dynasties have their inner triangle conforming to these ratios.

Introduction to Proporzione Divina

Proporzione Divina features commentary on art and music by architect and author Bevin Chu.

Proporzione Divina is Italian for "Divine Proportion." The Divine Proportion is also known as the golden ratio, the golden section (Latin: sectio aurea), golden mean, golden number, divine section (Latin: sectio divina), or golden proportion, and is represented by the Greek letter phi (φ).

The Golden Section

From Wikipedia, the free encyclopedia

The golden section is a line segment sectioned into two according to the golden ratio. The total length a+b is to the longer segment a as a is to the shorter segment b.



In mathematics and the arts, two quantities are in the golden ratio if the ratio between the sum of those quantities and the larger one is the same as the ratio between the larger one and the smaller. The golden ratio is approximately 1.6180339887.

φ = (square root of 5 – 1)/2 = approximately 1.6

The Golden Rectangle

Many artists and architects have proportioned their works to approximate the golden ratio—especially in the form of the golden rectangle, in which the ratio of the longer side to the shorter is the golden ratio—believing this proportion to be aesthetically pleasing.



The Fibonacci Series

The irrational numbers of the golden section closely correspond to the whole numbers of the Fibonacci series, in which each number is the sum of the two preceding numbers.

The numbers of the Fibonacci series are:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987 ... ad infinitum

This makes the Fibonacci series highly useful for architects and designers who wish to make their buildings and designs approximate the golden section, but must as a practical matter use whole number units.

Divine Immanence

The Golden Rectangle shows up in the most unexpected places.

For example, it shows up in the 16:10 aspect ratio of the newest, most advanced LCD monitors, which provide more comfortable viewing than older, now obsolescent LCD monitors with 4:3 aspect ratios.

The newer 16:10 aspect ratio is more ergonomic because it more closely matches the human being's natural field of view, formed by the two overlapping fields of view of two side by side human eyes.



Vesica Piscis: Latin for "bladder of the fish," two circles of the same radius whose centers lie on each others' circumference, aspect ratio of 3:2 corresponds to the fifth and fourth numbers in the Fibonacci series

The older 4:3 aspect ratio, by contrast, is noticeably less ergonomic because it chops off the left and right margins of that natural field of view.



ViewSonic Home Page (Traditional Chinese): "ViewSonic VG2230wm 22 inch multimedia liquid-crystal display, 16:10 golden ratio display ... high resolution golden ratio display 1680x1050"



The 16:10 aspect ratio of the newest LCD monitors reduces to 8:5, the seventh and sixth numbers in the Fibonacci series.
