Landis Tests + for blood doping

Crap.

This was a great story and probably one of the best rides ever by a rider after falling 8 min behind and making up 7 the very next day...

Hope it is some French conspiracy. But it could explain the very good and bad days.

I haven't seen any stories that suggest it's him? They just say it's a cyclist and that they'll say who later, like they did for the others. He's MIA, but I'm willing to bet he's off getting that surgery he postponed for so long. I hope so, anyway. That would just crush me.

Its on 3 diff. news sites. His team confirmed its him. Maybe they news sites are all reporting something wrong but I doubt it. Dammit again.

AIGLE, Switzerland Jul 27, 2006 (AP)— While the cyclist who tested positive for doping at the Tour de France won't be identified until backup tests are complete, it does not appear to be any member of USA Cycling including champion Floyd Landis.
The International Cycling Union said Wednesday that an unidentified cyclist turned in a positive doping test during the Tour, widening the scandal that gripped this year's race before it began.

His name, team and nationality won't be released until the testing process is completed, including the analysis of a backup sample.

It doesn't appear to be this was 32 minutes ago

4th news agency...

CNN reports Floyd Landis has reported + for elevated levels of testosterone. His teammates confirm the report.

Now its testosterone. This is a bit more bizarre. One can have elevated testoterone levels at different levels naturally.

This Sport is for geeks.Doesn't surprise me that the resident Science teacher is interested.Tell me this,teacher,if the blasting power from many explosives comes from the massive amount of energy released from nitro-organic compounds(when Nitrogen gas is formed,)then why doesn't it also take a great deal of energy to form the nitro-organic compounds?(or does it indeed take a lot of energy to form them.)For instance,this compound:

How is this sport for geeks? I love cycling and am an aspiring amateur racer myself. I bike commuted every day of the work-week last year, through the rain and the dark, and it was the most addicting thing I've ever done! If nothing else, you get incredibly sexy calves and a seriously good cardio workout pumping up those hills...my partner's never looked hotter to me, and we both enjoy tearing across town together.

Just read the news about Landis. So bummed...although I do wonder about it, I mean, the guy has been a rather outspoken critic of dopers, and I'd imagine that he could have had some extra testosterone from those painkillers he has to inject for the hip. I guess either way, I still admire a guy who can ride the toughest race in the world on a dead joint. But man...I really hope it isn't true. Seems like the process of dope testing, as well as the how the results are interpreted, is extremely controversial. I wonder why?

When your foot slips,you guys must really get some pain in the loins.Not for me.

[irishtrekker]

Well, I use clipless pedals (I "lock" in), so that's not a problem for me. Once you learn how to snap out, you'll never go back (and it only takes one or two falls because it's never fun tumbling over at a stop sign when you're still attached to the pedals). It's also fun to tear past the hotshot guys who think they look so cool riding sans helmet on a bike that doesn't fit them right...oooh, and they just got scorched by a girl.

Not that I'm competitive or anything.

i wont get into cycling until Ullrich and Basso come back, first time in 10 years i didnt give a **** about cycling and the tour de france in general since they banned them

The conservation of energy is a powerful idea my good little dawg man. Here is the deal. Chemical bonds contain an enormous amount of energy. In fact the atom itself is held together by very powerful forces... thus breaking the atom, the atomic bomb, was quite a display. The bonding energy between the protons and neutrons of the atom is massive, getting it to come apart and to convert it into other forms of energy, heat, sound, and various forms of radiation, is a task we have sadly mastered. So quite simply, when the universe first cooled enough for atoms to actually be formed, that energy was trapped. We found a way to release it. The energy was already there when the universe first formec.
Now in explosives what you are basically doing is breaking chemical bonds that in most cases already exist. The energy is already there. All one is doing is taking chemical bond energy, and making it easier to turn into an enormous amount of heat energy very rapidly by tweaking a few bonds here and there and that does not require much energy. Kinda like pushing a big boulder on a frictionless surface 1 mm closer to the edge of a cliff. The heat energy released in the structure you found turns into gaseous products very rapidly which must expand. That my doggie lover, is an explosion. Wrap some tightly bound metal around this compound (that turns to gas very readily creating enormous pressures) any you got fragments of the metal shearing into millions of pieces and you tear a lot of people to shreds. Quite a horrible thing.

(CH2)6N4 + 4HNO3 → (CH2-N-NO2)3 + 3HCHO + NH4+ + NO3-

The reaction above taken from your site, is just the sythesis of said explosive. The first compound right after the--->

This reaction looks to me to be exergonic on its own. So you actually use no energy making the stuff, you give it off. So just making the stuff that is the explosive requires no energy at all, if fact it gives off energy. Thanks for the information.

One of my favorite teachers in the world taugh me physics for two years in high school. He was an amazing guy -- Vietnam vet, avid scuba diver, smart as hell but completely genuine and able to connect with all of the freaks and geeks like me...I still think about him and wonder if he's enjoying retirement. Sorry, totally OT, but just wanted to let you know that I think good science teachers are just fantastic people.

Yeah,you're getting a ton of energy released(when N2 GAS is formed.)To make these compounds that contain the Nitrogen,it doesn't seem like you are putting a lot of energy in(to make those,)but you sure get a ton of energy out of them.This is not supposed to be the way it works.Usually energy in,and energy out.What am I missing?

The energy is already in the compounds Scuds. When the universe first formed it started out with the same amount of total energy we have now.

I'll give an easier example. When a tree uses its leaves to photosythesize, all sorts of compounds can be made... including wood (basically cellulose, paper is made out of it). We would call that growth. The tree dies. We take the wood and release all that energy trapped from the sun. Combustion. We burn the wood. We are basically releasing trapped energy from the sun when we burn wood. Now the question is, where did the sun get the energy... When the universe first formed from the big bang. Where did that energy come from? who the hell knows.
So all those different atoms that formed when the universe first formed have that energy already trapped in it. Some is released in nuclear reactions within stars (suns) and some is released in a myriad of other reactions.

Oh yes. When I say released, I mean the energy is converted to a diff. form. As far as we know, energy is conserved. None is gained, none is lost, it just changes form. Like the tree example. Sun--->chemical bonds(wood)--->heat and light upon burning... energy just changes forms

I wish I had a teacher like that.

Its just that the more you understand about the way the world apparently works, the more control you have over your own life. And really all kids want is to have a say in what they become and the way they live. Most are ready to get out of the house. So I attempt to arm them with an understanding so they can make their way. I think most human beings want to be in control of their lives, or at least want to know what they can and cannot control. That is very comforting for most people. Im tired of hearing about people getting pushed around because the have not the foggiest notion of how things work... socially or scientifically.
Education helps sets people free to do what they desire.

For those who like nice clean explainations, this is a great site:

Sorry to digress from Landis. I am done.

These compounds have to be made.I understand about just watering a tree gets you various fruit etc.(because the sun is providing the energy,and the sun is free energy.)The sun doesn't make these explosives.Are you saying the chemicals used to make these explosives are energy rich compounds that the sun etc. helped make(or these substances occur naturally,and that's why we don't have to use a ton of energy to get a ton of energy..from a bomb.)

[whorstman]

Cycling analyst John Eustice thinks Floyd Landis' testosterone test could be a false positive. Landis' testosterone levels were low; just the ratio was off. Landis' cortisone shots or beer drinking could affect that. We should know the "B" sample result within a week, Eustice said on The Dan Patrick Show.

Every atom in your body has the potential of releasing an enormous amount of energy. Every atom in the universe does. When the universe first formed there was a certain amount of total energy. It remains the same.

The only problem is how do we release this energy within the atom. Its there... "naturally" from the beginning of the universe... actually a little after, when it was cool enough for these atoms to actually form.

Now for compounds ... atoms that are, we will say, stuck (bonded) together.
Bonds are basically energy harnessed in electrons of the compound. Electrons make bonds possible. Electrons exist in compounds at a number of diff energy levels. These compounds were also created "naturally". Again the problem is releasing this bond energy. If we can make the compound a little less stable, by adding some atoms artificially, like the reaction given in the other post, we have essentially moved the boulder (the energy tied up in the chemical bonds) to the edge of the cliff. Just a little push now and bang...

If you need me to explain further I will. Gotta go now.

I thought his comeback ride after that bad day in the mountains was just too good to be true, I had never seen something that extreme in the sport.. he looked dead and buried one day and was as fit as a flea the other.. I Like the man, its a good story but.. its really is a shame
