Re: I'm 13 and wish to have a good education.

Come on, people. Ok, to the original poster: yeah, your post sounded kind of pompous. Let me tell you, it's damn hard to not sound pompous when you've got a good vocab and you haven't been writing for that long (and at 13, it's kind of impossible for the guy to have been writing that long). Don't ju...

Re: "We need a new definition of privacy"

Er, right. I am not sure your analogy perfectly corresponds to the situation. :) My point was that my use of facebook is not a waiver of my right to privacy. I mean, sure, every time I put something on the Internet, like for instance this post, I am assuming that people will be able to read it. But ...

"We need a new definition of privacy"

http://www.cnn.com/2007/POLITICS/11/11/terrorist.surveillance.ap/index.html Evidently, this guy thinks that since I'm on Facebook, I must not be using my right to privacy anyway. The scariest part: "Privacy no longer can mean anonymity, says Donald Kerr, the principal deputy director of nationa...

Re: Non-existing physical constructs

I would like an object with zero gravitational mass and 20kg inertial mass, of about the same density as rock, and the consistency of very hard rubber. Actually, I'd like a whole set of them of varying masses, kind of like dumbbells. Preferably spherical; think of the fun games you and a gang of bud...

So I was thinking about relativity...

I am a grad student in chemistry, with some physics training particularly in quantum mechanics. I know next to nothing about relativity, however. One of the things I remember from high school physics is that the observed mass of an object increases as the Lorenz factor, (1-v^2/c^2)^(-1/2). So, I env...

Re: POST HERE FIRST - INTRO THREAD THE THIRD

I am 23, a grad student in materials chemistry, and I enjoy reading stories, the martial arts, and being outside in fall. I am married to a girl with curly hair.

I hope this is the correct sort of thing to put in the intro thread.

Re: SF suggestions for the SF newbie

I would like to put in my vote for the following: Moon is a Harsh Mistress, Star Beast, and Citizen of the Galaxy by Heinlein The Wizard Knight and the Book of the New Sun by Gene Wolfe (danger: the latter is heavy fare) The Mote in God's Eye by..um...was it Pournelle? Snow Crash by Neal Stephenson ...

The cat in the box is in an indeterminate state, neither dead nor alive, until an observer opens the box and observes the cat. This act collapses the cat's wavepacket into the dead or alive state depending on what the opener observes.

Resonant frequency of coffee

Hi all, This was so dorkily intriguing that I registered for the xkcd forum just to get other nerds looking at it. So, I thought I was totally incapable of walking down the hall with a cup of coffee without scalding myself. No matter how careful I would be, an oscillation would inevitably develop wh...
