BSW really is a great place to play strategy games online. Not only that, it is a good place to try out a game and see if you like it before spending $40 on something awful at the store. The only downside is that it can be a bit intimidating and un-intuitive to someone new to the system. Esp if you don't speak German. However there is a great website for all of us english speakers to help get the feel of the game. http://englishtown.brettspielwelt.info/ I would also recomend downloading the client and not playing in the browser. It's java based and mulit-platform. Plus if you get the client, the english town website has an english config file for it which translates all of the controls for you. Best of all it is entirely free and litterally filled with players so you can play any time you like.
On their website they explain that they drill holes of different sizes in the bottle caps, then have a paperclip sticking through the hole that is holding the mentos out of the diet coke. All they have to do is drop the paperclip into the coke and the reaction goes. Different sized holes create different height and length sprays. They also had some where they also drilled into the sides of the bottles to create other effects.
And it is about the amount of data that will be stored each year per detector at the LHC (large Hadron Collider) in Switzerland. I remember as they were designing it how one of the big questions was on how to transfer all of that data from Europe to the US. One of the proposed solutions being to fed-ex (or some equivilant) boxes of magnetic tapes every day.
Everyone say it together with me: "Phase velocity vs Group velocity"
There are no photons in this experiment that are traveling faster than the speed of light. Only collections of them that 'appear' to be doing so. Think of this as an example:
I space people out in a line, each of them two light minutes apart from the people next in line (all at rest with respect to each other). Now I go about talking to them and informing them of my plan. At 12:00 the first person waves, at 12:01 the second person waves, at 12:02 the third person waves, and so forth. My "wave" is propogating, therefore, at twice the speed of light.
This is the same thing that this experiment is doing more or less. By spending extra time setting up the experiment, you can make it appear that a light pulse travels faster than c, but like my "wave" it is only an appearance.
As several others mentioned gnuplot is a great program. If you would like a bit more GUI with your plotting I would recomend Grace (formally xmgrace). Its Free too.
Website: http://plasma-gate.weizmann.ac.il/Grace/
It only does 2D plots but handles them very nicely, can do fitting, read tables of text file data, and is very customizable as far as lables go. I use it to plot out most of my data by pulling it straight from the output through an awk script to format the data slightly and then open Grace. Give it a shot.
Good luck with 3D plots, but I might recomend maple. Again with a bit of an awk script you can format the data into a form maple can read and plot out.
If you're cheap, like me, but want a laser printer, check out the Samsung ML 2150 models. Cost me less than $200 new, with a toner cartrage. Duplexes, hasn't ever jammed, and is generally reliable as anything I've seen. Sure I'm not printing hundreds of pages a day though, but if you want a printer for home use, you'd be hard pressed to find a better deal. Oh and they have several variations so you migh look for 2150 2151 2152 etc.
Although its been a few months since I've last tried. I recall hours upon hours trying to build fetchmail to worth with Kerberos 5 authentication. And after that failing because mit updated something but fetchmail didn't, or the like. And as far as I know, everyone at school here (Iowa State) has had the same problem.
So I say "boo to kerberos!" Or at least boo to requiring it exclusivly over any other secure methods of remote access. My solution to this problem is one I would recomend to anyone trying to get around kerberos e-mail authentication is to simply have your e-mail forwarded to a g-mail account and pull it off of there to your box. Here at ISU, at least, its pretty easy to get your mail forwarded to another address. Again, "down with kerberos!"
Offtopic question. Were you in the physics department at Ohio State by any chance? It's the only place i've heard of people talking about physicsphairies and google seems to pretty well confirm that.
Orchids are not actually as hard as you might think to grow, and are beautiful too. If you go the the store and buy the ones without flowers, they are even very cheap ($10 or so). Just be sure they get enough humidity. There's plenty of information online about growing them, and the flowers are definatly unusual.
I came home for the holidays and got busy cleaning up the family computers like always. I happened to notice wintools there as well. Well after running adaware, stinger, trying to delete it, end task it, etc..... I just went into add remove programs in the control panel and there it was. Uninstalled as easy as could be. I always have to laugh when I forget to try the obvious and just go to the heavy handed stuff right away. But if you ever come across wintools again, keep it in mind.
There are a few places where using i makes sense. Albeit it will probably get squared at some point. I'm thinking in quantum you can use a potenial of the form V= A+Bi where B is an absorbsion so that it 'sucks up' probiblility from the wave function. Or anytime you can talk about forier transforms etc you can wiggle i in. But generally yeah I supose they are pretty contrived however sometimes you just need the concept that a number squared is negitive.
Does any one know how much they spend researching, designing, and building this? Alternativly does anyone know the price tag if I wanted to have another one built? At 5MW it should provide power to between 4 and 5 thousand people and I'm just curious how it compares to other power plants in cost, wind or otherwise. Sure is impressive though.
Iowa State University also uses kerberos for for their entire system and I think several other universites do too if I remember from my searches on how to set up my linux e-mail to work correctly with it.
On a related note, does anyone know of a linux e-mail client that actually will use kerberos_v5 authentication well? I've tried setting up fetchmail to do it, but kerberos_v5 isn't compliled in by defalt and there seems to be some bugs in the code that prevent the compile from working now that MIT has changed a few pieces of the code. Oh and I'm running Mandrake btw. I'd really love to stop using webmail so any sugestions would be great. Thanks
My brother and I took and old 386, a set of rail road spikes, and a large sledge and made a mobile for the IT office where he works. If you've never done it, pounding a rail road spike through a hard drive, CDROM, power supply, motherboard, keyboard, mouse, and various exansion cards is a lot of fun and great stress relief. Esp when they've been giving you hell and acting up.
While my physics is a bit rusty, I do recall that the magnetic field drops off like 1/r^2 (or is it 1/r^3, i'm do lazy to do the integral or look it up now). Thats very fast. Also the drop-off is scalled by the physical size of the magnet which is why more powerful ones are used. They can have just as strong of a field close by where it is needed and almost no field far away. Try it, rip apart a hard drive and see how strong that field is even half an inch away.
I've actually had Mathur for classes as I'm an undergraduate at Ohio state in physics. His tests really are not all that brutal as he is both an amazingly smart man and a good teacher. He has this dry humor that you have to pay attention to to get. Amusing quips include:
"It will be a big piece of fun" (talking about deriving equations)
"thats a rather large force" (after mentioning that the force to pull two pieces of a capacitor apart could lift the city of columbus)
If you get a chance to meet him, don't pass it up. He's a great guy
At $150,000 per song or movie traded, and say 10,000 traded per day (I figure a low estiment) thats 1.5 billion per day. Say they sue for three years, thats 1.5 trillion in damages. I realize these are numbers just tossed out with no justification, but can anyone think of a lawsuit for a larger sum of money?
Forget DRM, let market forces dictate the business model for business.
The companies are trying to addapt to market forces by using DRM. Those that survive will just pick the right balance between making money and not pissing off customers.
If it works though, I think this 'squishy' solution sounds like it could be a decent compromise between the two. As much as we all know the recording companies are evil, it is stealing to rip off their stuff and they have a right to protect it. This could be a way to allow fair use without being a pain in the ass. Just my 2 cents.
The other day I was watching a movie in the theater and was handed a survey to find out how effective different marketing stratagies were. The question was: What made you want to see this movie. Myself, and all of my friends left all of the options blank and wrote in "we downloaded it from a p2p, and decided it was worth watching".
If everyone started writing this kind of thing, (true or not) the MPAA might take a second look. Can't hurt anyways.
My question is what is actually providing the energy to heat and break up the waste? Sure this sounds like a good method to get rid of waste but it isn't an alternitive fuel source that I can see. You still need solar or oil to break apart the Hydrogen. Nothing is free.

Assuming that he just 'tapped' the wires together long enough to create a flux, there will be a HUGE resistance in the wire from the fact it is wound and there is inductive resistance. Also resistance in a wire goes up for longer wires, and thinner wires. 5000 volts isn't unresonable. But I"d work with a very small current in that case.

As a virgin physicist, I object!!

I belive I read that it will run with winds of between 3.5m/s and 25m/s. With a nominal wind of 13m/s. Convert to mph or your favorite units at will.
