The flow at the seat post will never be clean, but this is mostly because of the head tube, stem, and bars. And about the seat post being within the diameter of your thigh, that is pretty insignifigant. The variation in the flow in the direction normal to your thigh is small enough that you can...

Yes, provided that the velocity of the stream is large compaired to the velocity of the moving body. In the case of a thigh on a bike, your leg is moving a hell of a lot less than ~15kph (relative to the bike), and the aero losses on a bike don't pick up until you are going greater than ~20 kph...

You have completly (and understandably) misunderstood the job of a jet aerodynamicist. A jet engine is a machine designed to move huge amounts of air, all of the aerodynamics of any consequence is on the inside, where there are fans, compressors, combustors and turbines that all have to interact...

It is really hard to do good wind tunnel testing... Particularly to acribe the cause of the losses to a feature of the item tested. That almost always requires a computer model that has been validated against the results in question. I suspect these results are not exactly diffinative...

Got any evidance to back that assertion? I did aerodynamic design of jet engines for 3 years, and your explanation sounds extremly, well, wrong.

Well, I give up... Nobody (with one exception) even bothered to attempt to answer the question, so I will tell you. I haven't taken ritalin since middle school, don't like the side effects... Seems like most of you assumed I take it still... Indicative of something perhaps... Anyway, if...

Yeah, I am pretty sure you don't understand me... :) I am not asking if you would think less of me, or think I am a cheater if I take ritalin. I am asking if you think I have taken ritalin recently.

Cheating or not. Do you think I use it to gain advantage? Besides, this is really directed at Flyer, you don't seem to point to the fact that people had medical conditions which required them to use medications that can be used to gain advantage (in the Lance/Greg case it is cheating) at a...

(Emphasis mine) Flyer, please don't take this as an attack, I am just trying to understand your thought process. I would like to tell you a bit about myself and then ask you a question. My brain is the part of me that is the most competative. I was on a state champion quiz bowl team...

I certainly didn't mean to sound like an authority on the subtletes (sp?) of UCI rules... Sorry. My understanding (quite possibly flawed) is that he is in a state of limbo right now where he is tentatively guilty, he will be officially guilty after his appeal fails. The only analogy...

Technically. I think you are wrong. He will have been found guilty when the appeals process is over. That is how USADA, WADA, and UCI work, right?

I acknowledge that Lance could be doping. Do you acknowledge that it hasn't been proven that he is? If Flyer and Veloflash had been saying "he is probably doped" rather than "you are a fool for not believing he is doped" I wouldn't have said a thing. Is that what you are about to do? Guilt by...

If people were saying "I think he is doping for these reasons..." I wouldn't have reacted. I am responding to the contingent stating, as fact, that Lance is doped, and that you have to be blind to not see it. Flyer (to name one) is responding to posts, that do not claim Lance is clean attacking...

Acutally, the lower the number the easier, .8 is easier than .9... it just happens that most bikes do not have gears that low...

The same can be said of you. You lack the ability to see that circumstansial evidence is not proof, this is obvious to most people. Is it obvious to you? You focus only on the theme of guilt by association. Logical Fallacy... Again with the guilt by association? You are using the conclusion...

If you are going to make an analogy, make it accurate. Arnold does not deny having used 'roids extensivly. He also appeared on video smoking marijuana in a 1977 documentory (I believe that he also used steroid in the film). There are mountains of evidence against the governor. If you...

Has anyone been able to find any data on just how rare they are? (besides the random anal extraction of a computation I did...)

Hey elrohwen, I know I am replying to a really old post, but... I assume you are talking about Glenn :) I'm just curious about your signiture, which hill is it? P.S. I started working for Cornell about 6 months ago, love Ithaca...

They had this on CSI? I don't watch much TV... My understanding of chimerism is that there are no symptoms of the conditions, and no side effects, it just happens to be the way you are, as such, even if you are an elite athlete/lab rat there is little reason to check for it, and thus it...

Could he be a chimera? A chimera is a person who has genetic material of more than one person. I did a little bit of googling, and I couldn't find out how common chimeras are... but I did find out that it is ussually fraternal twins who are chimeras (8% of fraternal twins...), but you can...
