In another book of Arthur Clack he proposes an entirely different way to get artificial gravity.
The spacecraft can constantly accelerate with acceleratin equal to 1g. This means that the articicial gravity force will be directed about the spacecrafts axis (immagine a simple rocket here) and the experiance of being inside would be like in a several story building with the lower levels located right above the engine. When the spacecraft needs to stop there would be a short period of 0g during which the whole ship changes direction to 180 degrees.
The obvious drawback is that we don't have enough power (and reactive mass to throw backwards) to constantly accelerate a craft all the way yo Mars and beyond.
A possible solution would be to have a nuclear reactor and use superheated water or a gass of some sort as fuel. In this way we get very high acceleration with relatively little "reactive mass". (in the book they used a small black whole that could accelerate the hydrogen fuel to speeds close to the speed of light:)
All of this being just a theory though. I got no idea if it can realy work.
This is not the best place for this but I'm too lazy to bother becoming a member of www.planettribes.com or some site of this sort for just one puny question. I'm interested in playing Tribes. Actualy here in my firm we play a LOT 3d team shooters and I kinda investigate new games for us to play. I don't care if Dynamix is no more. A good game is a good game and it's only peaty that the company is "shut down" if it made such a great (as I hear)game. Anyway I'm gonna ask you if Tribes 2 can be played on ATI Rage 8mb VRAM (peace of junk i know:P) because this is the majority of videocards we got here. On the Tribes site it says 12mb VRAM minimum and there are some GeForce-s listed and stuff like that. But a gamers hope never dies:P
I want to ask if any of you has heard of the SNMP ( Simple:P Netwark Management Protocol) being used yet? I'm having hard time trying to understand/debug this thing (yup it's true that BER is a major headache to debug with its idea of using the very last bit of data to encode something deeply meaningful:P). The reason is that the chief programmers in my firm claim SNMP is still widely used and it would be a good idea to support it. So is it realy widely used yet?
Has anyone heard of the Neural Net mathematical model? It tries ot describe the way the neurons in your brain work. Basicaly the idea is that each neuron has signal inputs to reieve inpulses and outputs to send impulses to the other neurons. When the neurons work they influence the power of the signals coming from their inputs and than forward the signals to the other neurons through their outputs. The brain evolves towards contiusness (or image recognision, speach comprehension etc.) when with time each neuron "calibrates" it's output. Finaly the result is the ongoiong "sparkling" of the whole neural net as signals jump from one neuron to the next forming memories, images etc. I think of the interenet it does nothing like that. Firts the signals introduced in the system are chaotic and for mostly noise. They are not organized in images or sounds or ahything that can stimulate the neural net to addapt towards something like image recognision. Even if this agrument is not viewed as too important since we don't realy know how the mind works there is a problem with the "calibration" itself. We are the ones that calibrathe the nodes of the internet and I don't think that we follow some global pattern that could spaw intellect.
Perhaps there is still a chance for intellect to evolve if we assume that after all in order to increase the performance of the net we humans fallow some golbal pattern. The problem is that once the intellect emerges in order for it to work it would have continue the "calibration" by itself overriding our interfearence. And this is unimaginable. Can you imagine your computer trying to reconfigure itself driven by some foreign force? Sounds kinda doubtfull:P
It depends on what you're doing ofcource. When it involves switching between entirely different things it basicaly can make you go nuts!
Multytasking sux when it comes to programming. At work I ususally have 2-3 entirely different things to program wich often includes reading tons specifications too. All the time someone bugs me about this and that crashing and why and the worst thing is that these are not things programed by me but by someone else. I basycaly define my job as a "Quality Assurance programmer". AKA I read specs, and write "test case" programs all the time and try to determine why the test casees I've writen before happen to fail now and then. Now 'xcuse me but the SNMP test case just failed and they whine on my had to explain why:P
It is a beutiful picture concidering the fact that it represents soemthing meaningful like linked websites. By looking at the picture I recon the algrythm would determine the "elevation" of each pixel from he plain. Maybe it will interpolate the elevations between several major pixels on the plain represnting the most linked sites? All thats left is to determine now the algorythm maps "elevetion" to the links topology;P

I am on topic. Sorry for not making my point clear. I ment to ask if any of the MUTANT CANCER "immortal" cells actually DIE (I'm speculating with the word "immortal" here:) or almost all of them manage to devide. I'm just interested to know what realy is so special about these perticular cancer cells and the only thing that comes to my mind is this. Meybe their agressivness (someone wrote about that) is realy about almost all of them managing to devide and thus keeping the colony evergrowing?

As I understand it these cells multiplicate endlessly as long as there is food arround to provide them with resources to do it (does it coast much for a laboratory to get a piece of such a cell colony I wonder:). What I don't get is why can't other cancer cells do that? (or maybe not only cancer cells).
Another thing that comes to my mind is that after so many divisions (that's how they multiplicate right?) these cells must mutate and become who knows what. So can they be still used on the basis that they contain human DNA?
And finally the last thing that comes to me mind (just now:) is if any of them cells actually die or they only divide? That would be like they are realy immortal right?....cool i think:)
