woe is me. I have committed one of the seven deadly sins: not reading the full post before commenting. my bad ;l

Put down the beef. Would you eat meat if and only if it had died of natural causes?

We had a bonfire at usf last week. They had firefighters nearby, it was rediculous.

I just turned it on. I wonder if there is a built in leaderboard. I'll have to make one if theres not so we can all see. And there should be some sort of prize, whats a reasonable number?

I wonder how many of the originals here signed up because of jinx's persistant spamming all over the place. He would post all over message boards "New science forums created by yale scientists" and in chatrooms "Click here for XXX!"

Yes, thats a primary alcohol. They CAN undergo halogenation, but not via SN1 pathway (which I was assuming what he was asking). Basically what can happen is that the alcohol gets protinated, and then a nucleophile attacks the backside of the carbon atom (relative to the leaving group) and "kicks out" the leaving group, rather than waiting for the carbon to ionize on its own, then attacking the carbocation. This results in a stereochemical inversion of the molecule. There could be other mechanisms that I'm not aware of yet, I'm only 1/2 way through the first semester of the course.

The thing about it is the people were so blinded by their leader that a good portion never realized how wrong they were. I'd hope I'd have the courage to stand up for something like that. Today's society is more about self-preservation, rather than standing up for beliefs. If the choice comes down to changing beliefs (or what you outwardly state as such), and death, most people would choose to change.

psh. dogs <3 I'd hate to have to dissect a puppy :l

MOSS, ROFL. That has to be the single most boring thing to dissect ever in the history of dissection. But yes, as far as I'm aware, most highschool bio students get to dissect a myriad of animals, including fetal pigs and/or cats.

I suppose its considered cheating to use a strong acid to create one.

dang! I think I've seen the piano launcher as well. thats pretty sweet though. I can't imagine a bus actually launching though.

we need to clean out the emoticon and get some fresh ones in there. anyone have any good sources :/

lol. Fetals pigs were suprisingly unfetal like. They were (as far as I could tell) fully developed and ready to be born. They even had eyelashes. They could have been cute if they weren't so pale and smelly. They also had dye injected into their bloodstream so we could find the major blood vessels easier.

Its because the intermediate step requires a carbocation, which RARELY (mostly never) form on primary carbons. What happens is that the proton bonds with the alcohol to form a -O+H2 substituent, and then water breaks away from the molecule leaving a carbocation. This will never happen on a primary compound.

lol. we dissected fetal pigs instead of cats. Much more appealing to people with pet cats, I suppose (although I was all for the feline frenzy that would ensue)

::prepares noose::

i HOPE you did not just post a spoiler

haha, I saw these on the discovery channel when they were airing a pumpkin launching contest.

of invisible mode that is. Privacy? You're on a public forum

hrm, i'll fix that. Even so, whats the point?

There is a lot of work going on in the background that people never see. I just look smooth

I think it was a thought experiment by wheeler. Here is some good info on the effect. http://www.bottomlayer.com/bottom/kim-scully/kim-scully-web.htm Its the famous delayed choice quantum eraser paper, with commentary in plain english. Its pretty neat how a pattern registered by positrons at Time1 depends on information gathered at time2 at the conclusion of the experiment.

Acutally, now that I'm checking up on it I see that white gold is considered harder because of the nickel alloy in it.

If I recall correctly platinum is harder than white gold. White gold is actually regular gold mixed with some white metals. Thats why white gold needs to be coated anually, and platinum doesn't need to be.
