Physics, Astronomy & Cosmology / Radio Wave Electrical generator?

« on: 04/05/2007 01:28:24 »

The way crystal radios work is they have an antenna that gets hid by radio waves in the atmosphere and send electricity down the wire to a grounding point. Before it reachers there one of the frequenceys is seperated out and powers a little speaker to hear whats going on.

If theres enough energy to power a speaker in one frequency, why not set up large grids of antennas each taking every frequency of radio waves and use them to charge a battery or what now?

Physics, Astronomy & Cosmology / Absolute Zero...Absolutely !!

If you apply string theory (which i have a rudimentary grasp of) to this, there can eventually be a point at which nothing exits.
As the universe expands infinitely the energy becomes more dispersed. On the strings level, if i understand correctly, once the energy gets so dispersed they don't have the energy to vibrate, matter ceases to exist.

Fine....ignore my question...you probably think its a flame or troll or what ever, but im serious, what would the reprocussions of having a FTL bullet be?

How much for one though!!

General Science / Dark matter compass

« on: 26/01/2007 00:51:08 »

hmm well i think that the problem with this idea would be how dark matter interacts with normal matter...
Can dark matter exert a force on normal matter?
Is there sufficient dark matter on or around earth to do this?

How much would it cost...

hmm well as far as increasing UV by .1% annually, this wouldn't necessarily cause them to evolve into a more UV resistant strand, if they produce this anti-UV chemical naturally in response to UV light.
You could jsut blast them with abnormal amounts of UV and they would compensate with abnormal amounts of anti-UV stuff.
This is what marijuana in hydroponics exposed to excessive light do with THC.

Secondly, you could take the normal grapes now and perhaps isolate and concentrate this chemical out of a bunch of them to produce a concentrated version of it (this would actually be the cheapest process)

Thirdly. Putting it in a retrovirus to be put into human DNA MIGHT work, but probably wouldn't, and really **** up humans, besides the FDA (here in America anyways) wouldn't allow it...ever...


Also theres always the possibility of artificially creating this chemical...

General Science / Re: Possible way of starwars ish holographic device...

« on: 04/01/2007 06:24:24 »

yeh, what i need to find is
1. What sort of particles have the property of being able to, for a small amount of time, emit red green or blue light when hit by an invisible beam of some sort and being levitated ultrasonically to different heights (to create a 3d feild of pixels) and peing mostly invisible to the naked eye when not turned "on"
2. is it possible to aim some sort of invisible-to-the-naked-eye-beam at a specific, tiny point in that feild, without triggering other pixels...

General Science / Possible way of starwars ish holographic device...

« on: 03/01/2007 05:50:50 »

Ive recently conceived of a possible way to create a sort of holographic device...
It would use ultrasonic levitation to lift tiny particles to different heights, filling up the holographic space, and these particles could have the property (if it is possible idk) of emitting light when struck by different EM waves...
that way, given vary accurate aiming and targetting and perhaps a red green and blue version of each molecule, would it be theoretically possible to have this produce a 3 D image that was semi transparent and stuff? A hollogram?

General Science / Re: Is It possible to re-heat a hot -water bottle in the microwave ?

« on: 03/01/2007 04:33:27 »

i heated water bottles in the microwave once.
I suggest removing paper on the bottle if you must (it has caught fire on me before)
and do not suggest drinking it (there is the controversy over plastic particles leaching into the water)
 besides the bottle might melt sort of, definently do not leave the cap on when its in the microwave unless u want a water bomb, and exercise caution if u must do that.

yeh i have mostly just put music into a big relaxing music playlist i play while i sleep
but i could try to make it more specific

« on: 29/12/2006 20:58:52 »

i slept last night withotu music...it was harder to fall asleep, and i have no recallable dreams...
And another interesting note...4 times i have woken up while the song american pie was playing!
(i have a special connection to that song due to a summer camp experiance...CTY, if any of you know what im talkin about....probably not)


I have a theory, perhaps the songs i hear at night associate with my dreams and then when i listen to that music when i wake up, it reminds me of my dreams?

the past 2 weeks ive been listnin to music when i sleep...
and it seems to be making me remember my dreams more, or perhaps have more dreams...
any one know why this could happen?

« on: 29/12/2006 05:19:17 »

if i were to posses a gun that could fire a bullet hundreds or thousands of times faster than the speed of light (impossible i know, but IF i could) what would the repercussions be? could i kill someone before i pulled the trigger because of relativity? what would happen?
idk just curious

yes you could be god!
but, i think flying spaghetti monster is more likely god!!! ahhaa


yeah this is what richard dawkins has been saying...
you can't disprove the existance of any god

hey i could be god too  []

My flying monkeys would destroy your flying spaghetti monster so there  [] [^]

How do you know i am not simultaneously a spaghetti monster and flying monkeys?

Doctor Beaver claimed this last spring and went away for a little "vacation" at a "friends" house for a couple of months. He has been much better since.

For example, the doctrine that 1 + 1 = 2 is not necessarily true, but we accept it as true, the only reason we say it is an un arguable true fact is that all the world accepts it as true.

No. This is false. Logic demands that 'true' be proven by a repeatable test. one apple and one apple always equal 2 by the definition of the numbers in the system of logic called arithmatic.

 

but my point is that the logic system called arithmetic might be flawed, or your perception of the results of a repeatable test could be flawed. You are stuck believing that you know things which are absolutely true, thats where you are wrong. You think you know things as absolutely true, the things you know and think are not absolutely true. Mine are.
