Oh god, you are a trip. Every formula in physics, and this is a physics question, is a math problem. Refining the problem with new variables to make a more accurate...oh to hell with this, I like talking with DigitallyCrazy more. You're just arguing for the sake of arguing. Find someone else, kid.

You're confusing a priori probability with a posteriori. In the cup example you give, my odds were 1/3 when I made my choice a priori. When you remove a cup the odds become 1/2 a posteriori; I change my estimate based on new information. This is the entire subject of Bayes' Theorem, which describes the Monty Hall…

This is my point; the video is wrong. Bob's death would give Alice information only if a) Bob chose after Alice, b) Bob knew which berries were poisonous, and c) Alice knew that Bob knew. If Bob chooses randomly, as the video seems it imply, his choice and subsequent death provide no information for Alice. It reduces…

Yep, Bob randomly picks one that happens to be poisonous. In a Monty Hall, he explicitly chooses a door that will have a zonk.

I once saw one at a house I was visiting for dinner - sat down in it after dinner while the rest of the party were talking, and fell asleep. Now admittedly I was 18 at the time, so somewhat more flexible than I am now...but yeah, I'd say comfortable.

This looks like it's either a scam, or these guys are way out of their depths. These cables have two copper wires and two optical wires per cable. Anything that needs more than two conductors (so anything other than 3.5mm audio connectors) will need expensive optical transceivers to convert the signal. For HDMI, those…

I see your 1406 and raise you 927:

Was there supposed to an infogram attached or something? Did all 81 million remove the album?

It actually depends on the size of bullet and how its designed.

Some bullets are small enough that only a well placed shot in the right place will stop some one, some bullets are big enough but shaped so they pass right through a person or object and thus pose a hazard to those behind them. Some bullets expand inside a…

Sometimes, they don't 22 or 9mm bullets have a long history of not stopping people, that's why the vast majority of police depts carry .40 or .45 caliber guns for the stopping power of the round. And even then its not a 100% guarantee stop. This round is designed not to penetrate the person and everything behind them,…

I have a video of a man shot by 11 rounds of 9mm FMJ by a police officer. He continues to the back of his truck to retrieve his shotgun and return fire at the officer. Luckily, the officer reloaded fast enough to add 4 additional wounds to the would-be murderer, killing him. With bullets like these, that officer…

Thanks for your reply. You'll be happy to know that research regarding adolescent and pre-pubescent ("tween") attitudes and behaviors with respect to parental notification laws for sexual health concerns abound. The medical establishment has actually studied this for decades, and while there are too many papers for…

I say this as the child to a mother who was 15 when she had her first and 17 when she had her second. I would have dealt with only a fraction of pain and hardship had someone taken me from my mothers care before I was 10 years old. So many of the problems I struggled with up until my early 20's go back to the sense of…

DigitallyCrazy - I think you are making a valid point and unfortunately the vitriol you are getting in response is preventing an even-tempered discussion of the important issues surrounding medical decision making in pediatric patients.

Ah I see, for the stylish douchebag

I don't think so. Even professional photographers have gotten into trouble for this. Unless they got model releases from each and every person, allowing them the rights to the image, I don't see how this isn't a violation.

If it makes you feel any better, working on a Ph. D. in physics seems to repel women, too.

And yeah, of all the female physicists I know (which is, admittedly, not a whole lot, all things considered) exactly 2 are dating/married to non-physicists.

Honestly, this matches up pretty well with how I feel. (Minus the bit about God.) Did Zimmerman do some stupid, obnoxious, and aggressive things that led to him killing someone? Absolutely. But as far as I know, the stupid, obnoxious, and aggressive things he did were not actually illegal. And as for the…
