    Bad dreams/nightmares

    I've had my share of nightmares certainly, but they've never been recurring ones. I'm not a psychologist or psychiatrist. By all means see a professional if it's causing a major disruption. Still: chronic nightmares -- by definition, being frequently occurring dreams unpleasant enough...

    Best way to destroy a hard drive?

    Thermite will do the trick nicely and is more fun than cat litter, according to a private communication from the national association of pyromaniacs. http://en.wikipedia.org/wiki/Thermite http://www.petitiononline.com/HUNGSOLS/petition.html

    Hidden Fees in IB

    And don't forget that commissions are capped at a maximum of 0.2% of trade value, so that stock price does begin to matter when the price is low. For example, the commission for trading 1,000 shares of a $2 stock is $4 = 0.002 * $2000 instead of $5.

    Holy death ray batman!

    Yup: I think it must be a high intensity microwave projector/focusser, probably a few megawatts power (MW) at minimum to have a serious effect on a crowd of people at 500m. Yes, the heat capacity (not the latent heat ... that's a different thing) of water is large. That's just a way of...

    Holy death ray batman!

    It's microwave, supposedly a 95 GHz beam. 95 GHz is pretty high frequency: it corresponds to millimeter length (3.2 mm) waves. These will not penetrate the skin very deeply, probably less than a half-millimeter, or so. I haven't done a real calculation of the penetration depth, since I...

    Don't tell me you think Yamasaki Assoc. is in on the conspiracy, too? I never said that. I said: there is no real reason to believe that they are right about what they say about concrete in the core. It is not merely my opinion that the likely source for the information [Hart, F, Henn...

    What really happened ....11 september

    The MIT paper that's been cited doesn't give a specific reference to any source for the claim about inlaid reinforced concrete panels in the core, and the end of chapter bibliography lists references that could be, at best, secondary sources for such information. Primary sources would be...

    What really happened ....11 september

    Yup. And it's even worse than that for the `squibs.' Video of some of these `squibs' is around which shows that the period during which the maximum amount of material is ejected occurs towards the end of the duration of the `squib.' They appear to be born small and then later grow large...

    Further on the simulated core temperatures on the 94th floor, fifteen minutes after impact, as depicted in Figure 6-36 page 127 of the report: It's actually worth estimating and recording the temperature for each core column from the diagram. There are six rows of columns extending left to...

    Happy to, but it will be harder for me to discuss WTC 7 and the others intelligently, as I have not made much of a study of the evidence so far. I regarded those collapses as secondary to the main event, and probably explainable by the large amount (1 million tonnes total) of rubble that fell...

    What really happened ....11 september

    It's not pure speculation that other diagrams were made. The diagrams I am talking about are in the report. You just need to look for them. And in fact, I think they already show that temperatures well above 300 C existed in upper layers of the air, over at least some fraction of the core...

    What really happened ....11 september

    There's no of course about your statement at all. You are comparing apples and oranges here. Air temperature does not equal steel temperature. Isn't that clear enough? Steel takes time to heat up. It doesn't immediately come to equilibrium with the surrounding air temperature, nevermind...

    Have you looked at the graphic of the 97th floor and compared it with the graphic of the 94th floor, that you posted, as yet? Nevermind for the moment what you or I think it is that the quote says. Let's just try to clarify this one issue of what can be deduced from the graphics about...

    What really happened ....11 september

    I agree that it is unclear from this quotation alone exactly what temperature is supposed to have existed, in the simulations, in the core upper air layer. But I think that the graphics clarify this somewhat. I didn't look carefully enough at them last night, sorry, and I will have more to...

    What really happened ....11 september

    But this is silly. You can't consider this one quote in isolation from everything else in the report. You're free to call what I say interpretation, but it is reasonable interpretation, given a great deal of other information that is present. Of course, you are also using `just an...

    What really happened ....11 september

    If something is unclear to me, it certainly doesn't mean that it's necessarily deceptive. There's another possibility than that it is deceptive, there are actually at least three: you misunderstand what is written, I misunderstand what is written, or both of us do. There's more than...

    What really happened ....11 september

    This quote describes the results of an actual experiment using materials and geometry similar to what was burning in the floor spaces of the WTC, which was done in order to test how well the fire simulation code (FDS) was able to simulate. Here, I'll add back in some of the important context...

    OK, thanks. I'm going to assume that this discussion doesn't change much in the final report, for now. I have them both, but comparing takes time. So it seems that what we have here is a statement that air temperatures in the upper layers of the tenant spaces above regions of active fire...

    What really happened ....11 september

    What is the page on which it is claimed that there were sustained 1000 C temperatures in the core? The only 1000 C temperatures I find mentioned in the report are temperatures that were reached in the simulations of the fires. Such temperatures are reached in the upper layer of air in the...

    To be sure, the building partially collapsed, but stood. The perimeter support columns failed on the upper stories, leaving the reinforced concrete core exposed and standing. On what basis do you say that? The Madrid building had extensive passive fireproofing for its steel structural...
