Hehe these are the things i never thought i would see on thg...

Aren't all of us computer folks just nerds at heart? 😉 So where better to find people with these ideas than THGC?

Make sure you are far away from your computer when you launch it...the EMP could destroy some data

You know, that's a very good point. You would definately have to shield the system well. Maybe it'd even just be better to get rid of the PC entirely for control. You could use programmable microcontrollers for the first stage and just use the USB port to program them. If you just rebooted the microcontrollers after each attempt and reloaded their code then it wouldn't matter if they got wiped in the process or not. Though that would be an extreme solution. I'd hope that you could shield them well enough to not even need to reload their programming each time.

i think the smaller models would be easy to sheild...but the larger ones...thats a diffrent story...i don't even know what is used to sheild EMP's....would it be lead...as it is the electromagnetic radiation that destroys data and since lead is dense i would not let it pass?

So easy to fry yet tastes so good...

Ooo, a rail gun... not bad at all. If it works, you can aim the damned thing at your door and hope some burglar comes in... install a security/surveillance system and you're set. You'll tear any unwanted trespasser to bits. *evil grin* "I hope somebody trespasses today... Oh no, is that irritating moron coming over for visit? OK, that's enough. Let's test this baby..." or something...
 
One more thing...

<b>*only read this if you want to know about cosmic rays... if you don't, this WILL waste your time.*</b>

Now seriously, Cosmic rays are cosmic rays because they're not from earth. They travel in space and reach earth with an immense energy (they're usually subatomic particles, like protons or electrons, or maybe something else) for their size. One of these particles - and they're terribly small - could hold the same energy as, say, a tennis ball travelling at nearly 120-130kph - if you consider that the tennis ball has much, much more mass, that's like 99.9...9% of the speed of light.

Upon entering the atmosphere, these particles collide with molecules and interact with the atmosphere in such a way that they break up into a greater number of less energetic particles. This happens iteratively, and so, in the end, a huge number of less energetic particles get to the ground and are detected by physicist's devices. This breaking up of the original particle is called a particle shower. When those particles finally get to the ground, this doesn't mean they'll stop. Some of the particles still cross the entire planet and exit the other way, so these particles are not often easy to detect, because they will only very rarely directly collide with a detection device.

After the detection data has been collected, the problem becomes a matter of reconstructing what happened, like determining the energy of the original particle and its inclination. This is done through numerical calculation and is computationally demanding. That 17-minute simulation was a simple case run. One of the mysteries of this whole thing is that a subatomic particle with "macroscopic" energy levels is <i>very incredibly energetic</i>, to the point that there <i>are no known natural astrophysical phenomena</i> that could have taken the article to that energy level, i.e. accelerated that original particle to those ridiculously high speeds. So determining particle source is a problem.

<i>Actually, I'm not working with those things now, but I'm very close to a group of physicists that is. Right now, I'm messing with Molecular Dynamics - I think I've mentioned this around here, but can't quite remember where or when.</i>

<b>See? I warned you! crazy cosmic rays session over...</b> :smile:

Hmm...

🙁

You know, when I think about it, I'm really not sure.

I mean if I remember my physics correctly (it's been many a year, so who knows if I am) EM radiation is a broad specrtum including radio waves, light waves, even micro waves. So the question really probably is more what wavelength is the radiation that the electromagnets give off? If I knew that, finding a material to use for shielding would be a lot easier. Heh heh.

Then again, are the two even related? 🙁

Where's a physics nut when you need one?

But if I did that then I'd have to take down the shotgun-trigger-on-a-string security system that I have set up.

Oh yes, right... but wait a minute... couldn't you just use them <i>both</i> on the poor trespasser? :evil:

Cleaning up might be a problem later, though.

Can't you reproduce cosmic rays with nuclear fission?

<sarcasm><i>Besides, we </i>all<i> know that the majority of the cosmic rays come from the interaction between matter and anti-matter at the edge where 'our' universe meets that of our evil twin mirror universe comprised entirely of anti-matter. And one day our universe will end and theirs will begin(because they go through time backwards) and then big <i>wang</i> will occur and flip our universes so that we become the anti-matter and they become the matter and the cosmic radiation will become the least of all of our concerns.</i></sarcasm> 😉

Hey, does anyone remember where I left my sanity? I can't seem to find it anywhere. :)

It's always in the last place that you look, but since I must have already looked there, having been the last place that I looked, then it must not be there yet.

Why am I suddenly reminded of an old White Wolf - Vampire, The Masquerade campaign...

Who put those tanks of mixed oxyacetylene in the sewers set to mercury switches in styrofoam floaty kid toys? Do you really think that the city officials will believe it was just sewer gas? Oh, you've already bought someone who can make it happen, well that's different then...

And will you please <i>stop</i> coating those magnesium pellets with an accelerant for the shotgun shells? We have more than enough already, thank you very much! I know that I <i>am</i> almost finished with the prototype of the fully-automatic 10-gauge 'snub' gun, but we won't need <i>that</i> many shells until we at least have a production model. Sheesh!

I'm sorry, I missed my calling sign there... :frown: I saw it just now! Sooo...

OK, here's the thing: you want to set up an electromagnetic railgun. The gun will use the magnetic force on a current-carrying projectile, or maybe a fuse just behind the projectile, to accelerate it to great speeds. Lab-built rail guns can shoot projectiles at speeds of up to 10km/s or so - this is why rail guns are so popular. Depending on the currents used, you might end up with an intense magnetic field - and you would want it to be intense, because this would imply higher projectile speeds *evil grin again*. So you will be using great currents, but you'll want to shield the external envirnment against magnetic and electric fields. I actually lack the knowledge as to how powerful a shielding you will need; however, you might do nicely with a diamagnetic metal-based solid faraday cage. I would imagine that a thick cardboard box wrapped in aluminum foil or something might do the trick, depending on the intensities of currents involved (this might only be enough for low currents, though...). I'll have to confirm this, because I'm just speaking off the top of my head and this is not really that simple an issue... And I <i>think</i> wood also blocks magnetic fields nicely. Don't remember exactly, though...

I'll check and come back later.

I've seen the commercial once, and I still can't get over how silly the whole thing was. I just honestly don't get Apple. Or maybe it's the community that uses Macs. I dunno, but either way I just don't get it. :\

Still, it would make for an interesting security system. Go ahead, just <i>try</i> to steal my Mac!

i guess thats what happens when macs get angry...

Someone should write a short story or a song about that.

<b><font color=red>When Macs Get Angry</font color=red></b>

It could have a tagline like... <font color=red>A Tale of Bloodshed and Woe</font color=red>

Or... <font color=red>One Rotten Apple Spoils the Bunch</font color=red>

ya know i used to remember when back in the day...macs would really get angry...the lc III's and the fist powermacs often would ask you to insert a disk after you removed it...then when you put the disk back in waited a while and removed it, the computer would ask again...this would happen over and over and over...scared me for life. I bet it had something to do with the OS not dismounting the disk...
