This is super - I have always wondered about this too. But now how about CD + DVDs Burning data on cds/dvds actually reduces the physical mass ama of the cd/dvd ama? So the more data you add the less it weighs or what? On Wed, Jul 15, 2009 at 3:49 PM, Davis Waithaka <daviswaithaka@gmail.com>wrote:

A8: First, currently (ie inside ur PC) data carriers are basically electrons. From classical mechanics (normal physics and chemsitry) we know that electrons have a definite mass. Thus data carriers have mass. However, data itself is not matter.. the analogy here would be that of the spoken word (data) vs air (sound/ data carrier) - the spoken word is not matter while air is.
We know from basic physics that for current to flow (for data to be carried across), there must be a complete loop circuit in which carriers come from A Source - to A Load - Back to The Source. The instantaneous mass M(t) at any given point on this loop, in terms of carriers, is thus constant [M(t+1)= M(t) + n - n = M(t)] where n is the number of carriers transmitted in unit time. Thus, whether the harddisk is full of data (spoken word) or empty, the number of data carriers (those with actual mass) is constant through time.
It is nevertheless important to note that from quantum mechanics the electrons (our data carriers in PCs) are considered to be levels of energy around an atom. Their position is simply a cloud of the probable positions where this energy can be found. This does not give us any indication of the electron being considered matter but as more of an energy wave concept - thus mass is out of the question, at least for quantum theorists.
A8 Second Part <I have always wondered about this, to add to it, Will the fiber cables become heavy in terms of weight once they start being used? :)/>
The above logic will be applied a bit differently: First, the data carrier in a fibre optic cable is light, does light have mass? Well, previously thought not to until it was demonstrated that its path can be bent by a black hole's gravity. However, the circuitry logic tells us that the light is not stored in the cable and that if 1 kg of light enters on one side, then 1 kg of light will be emitted at the other end. Using the earlier simple data carriage equation we can conclude that a fibre optic cable carrying data will weigh the same as one that is not.

I saw some documentary of NatGeo or Discovery, I do not know which, but they were able to transmit power tirelessly and power some devices. More like the way microwaves work. I guess in future it will be possible as the technology matures.
About the Nyayo Pioneer, I double Jeremy Clarkson would have had any kind words to say about it. He says really bad things about Bugati's and Maserati's, and the Pioneer is way down there, if it was a in a scale of 1 to 10, 1 being the worst, the Pioneer would have been like -100. That car was just so ugly.
Currently, internet crimes are tried in the country/state which hosts the server. They was a case of a woman who tormented her neighbor's daugher until she committed suicide, all on MySpace and it was being tried in California's where MySpace has it's servers.
So if you commit internet crimes on servers based in the Hague, you will go to the Hague.

Probably. But not in the way u think. Everybody emits some small charge. Now now those guys creating nanobots to cure or repair human tissue can use this elec from the human body to power the nanobots.

Q2: Is the shorthand for a Terrabyte TB? and what will 100 TB's be called?
Q3: Will we ever reach a dangerous state of security on the Internet that there shall be need for Internet Police, complete with warrants and courts? In which country will crimes commited on the Internet be tried?
Q4: WHY DOES'NT KENIC SELL DOMAINS ONLINE? for $9.99 complete with online ordering? b) Why do i have to buy domains from a third party?
Q5: Is the Opposite of Open Source "Closed source"? ^>alex$

But if you have an idea and I have an idea and we exchange these ideas, then each of us will have two ideas.
