Yes, the point of the Religion restriction is that you need 30 posts to be eligible to discuss religion. Unfortunately I have to close this.

http://www.theglobea...article1871149/ So, they're claiming to produce fossil fuels with photosynthesis, capturing carbon dioxide from the air. This is similar to research being done at my university: use algae that produce fuel compounds through photosynthesis, and just extract the fuel. But they're nowhere near producing $30/barrel of crude oil in the volumes that this company claims. If this company isn't full of BS, this promises a closed carbon cycle where carbon dioxide emitted by fossil fuel use is used to make more fossil fuels. If they are full of BS, well... we've seen this before.

I don't think it implies that every illegal post will be deleted, just that illegality is one of several valid reasons to delete something. When we allow members to delete their own posts, someone invariably gets angry about something and deletes all 200 of their posts, leaving discussions completely screwed up.

Brief notice: Section 5 of the ScienceForums.Net Forum Rules has been updated to more clearly describe the ownership and use of content on SFN. If you have any questions, send them my way.

You apparently haven't read much of it, since it addresses many of your concerns.

Twinbird24: You could try reading the NIST report (or at least the executive summary), or even the summary I wrote earlier in this thread, to learn how the collapse worked without melting the steel. NIST has run fairly extensive computational simulations of the collapse as well. ! Moderator Note Twinbird: Also, stop plagiarizing your posts. It's fairly obvious.

Looks like there's a known bug in the web chat client in IE 9. That's the trouble with using beta software, I guess. Microsoft may fix the bug in a future release of IE 9, I hope. You'll have to use another browser for now, since there's not much I can do to support a beta browser.

Ah. In cryptography, the current time is not considered a great source of entropy.

I'm fairly certain that anyone with a small amount of chemistry experience and some sort of grinding device could produce thermite at home in a few hours. I've played with it in high school classes.

In BASIC, is "TIMER" some sort of timestamp? If so, you're basing your algorithm entirely on the current time, which is something an adversary may be able to easily guess. Strong cryptographically secure systems (like OpenBSD's) use system entropy, such as disk seek times and random bits of memory.

I know a number of adults who use Facebook. I know the majority of students here do, even the science students. It's considered acceptable.

You can't get combustion without waste, CO2, or H2O. Your best chance would be hydrogen, but it produces water vapor. Otherwise, it won't be combustion, it'll be some other reaction type.

That is strange, and I wonder what sort of recovery features the boxes on those planes carried. Did they emit audible signals? Were they sufficiently crash-resistant to handle being flown into a building? Just how fire-resistant were they? I don't think NIST or the 9/11 Commission would have addressed this, so we'd have to look elsewhere for answers.

If you were The Government, and a building had just been demolished by terrorists in large planes, you would not see reason to keep around a few thousand tons of damaged steel, because you have no need to collect evidence. Terrorists in large planes just flew into the building. What exactly would you want to find? You certainly aren't expecting to need evidence to counter theories that nuclear bombs were planted in the buildings. The 9/11 Commission was set up a year after the attacks, and the NIST investigation around that time. In the intervening months, why would they keep around heaps of steel rubbish?

Yeah, that's Reload; redo is Ctrl-Y on Windows. There really ought to be an auto-save feature...

Good luck trying to hold your breath more than thirty or forty seconds while walking around in your house. If you trip, you're dead.

Decriminalizing drugs has worked for at least one country: http://www.time.com/time/health/article/0,8599,1893946,00.html

It was removed because it cited no sources, was original research, and made various demonstrably false claims. You can read the deletion discussion here: http://en.wikipedia.org/wiki/Wikipedia:Articles_for_deletion/Nuclear_demolition

Random new member. Feel free to undo it.

I am an undergraduate physics student (not at Harvard) who is required to perform novel research and write a thesis for my honors degree. So far, I haven't heard any complaints about "there's just nothing I can write about" -- in fact, the TA for my electromagnetism course had published papers on relativity while still an undergraduate.

WTC 7 didn't fall into its own footprint; it caused significant damage to neighboring buildings, some of which had to be demolished and rebuilt. There are no other historical examples, but WTC 7 had an interesting design and NIST has covered the collapse fairly exhaustively in their reports. Also, I think Tim Minchin would not approve.
