I agree fully with this argument. I don't consider it possible that such work could have been hidden. It simply requires far too much precision, far too many materials and is far too extensive in nature. You can't possibly do it with a few guys disguised as janitors on the night shift or some...

That is ... any mechanism short of a giant coming along and stomping really, really hard on the towers :p Sorry ... I should have said `lower bound,' here, not `upper bound.' Parts of the dust cloud are clearly still settling in various places for an indeterminate time, but I thought...

What is your evidence for this estimate and what on earth kind of reasoning are you using to determine how long the collapse should have taken? I do, certainly, agree that this time scale is a critical parameter in theorizing about the collapse. But your claim of 9 seconds seems highly...

Thank you, too, for your response. Experiment: No Way! An experiment on the required scale is completely out of the question. But I think it is conceivable to try to do a numerical calculation of maximum pressures and interfloor air flows that could be achieved in the tower collapses...

Now perhaps you would like to point to the positive primary evidence for explosive `squibs.'

Are you using so many question marks for emphasis? Or is that just a nervous tic? http://www.911myths.com/html/wtc7_damage.html

Google is your friend. As to credible, why is it that you think the pictures of the North side are `credible?'

Not until now, that is.

Here's a possibility: [0] The collapse begins at the top of the building and proceeds downwards. It's evident on all videos I've seen. No downward movement of a lower floor is apparent before the collapse front reaches the level of the floor. [1] The weight of the collapsing section of...

With 60K (USD) in the account you'ld be earning (LIBOR - 0.5%) on 50K, if it's all in cash, and you just let it sit at IB. There's no interest on the first 10K. One possibility, if you're going to be inactive for a reasonably long time, might be to do an ACH transfer of your excess funds to...

The US constitution was written before any of the current political parties existed, so originally, at least, it wasn't really done this way to serve the immediate interests of a particular party. Article I section 3 deals with the question of vacancies in the Senate. The relevant language...

Yes, that's my understanding. When you take a loss in an asset denominated in a currency other than the account base currency, you naturally end up with a debit balance in the foreign currency. IB calculates interest separately on the commodity and security accounts, and on the market...

Sad to say, you may be right. One day, a week or so ago, I think maybe it was a Monday or Tuesday, I had problems with ES. The quotes just suddenly dropped out. Prices were just frozen on the screen. That could be a real bad deal in some circumstances :(

Strange. It looks OK here on my end. 1409.84 just like you say.

The only dumb questions are the ones you don't ask :cool: I don't think stop limit orders are native to CBOE, BOX, thought I think they are native on ISE. So Scottrade must be emulating the order for you and they may trigger the stop if the bid is through your stop price. But you said...

It's true that many economists did important work on game theory, but I'm not sure if it's fair to say that economists invented game theory. For `pure' mathematicians, who made many of the important contributions it's a fascinating subject in its own right. The earliest reasonably modern...

Interesting what you say, lescor and Steve Tvardek: thanks for the insights. I still don't understand why IB would turn off all odd lot trading though. It seems like they ought to be able to auto-route all odd lot orders to ECNs in such a case, just bypassing the specialist. Stopping all...

Cheers, tyrant. Good trading!

RPN = Reverse Polish Notation. RPN is a parenthesis free way of writing algebraic expressions, which was first invented by the logician: Jan Łukasiewicz. So for example the expression (w+x) / (y - z) would be written in reverse polish notation as: wx+yz-/. The operands (wx) precede the...
