	edublogs: Kevin Kelly@Pop!Tech: Where does collective intelligence begin?
		Likewise, one quintillion transistors make the web go around, which is about the same as the number of neurons in the human brain.
		There are 20 petahertz synapse firings on the web and 20 exabytes of memory - the parameters of the web as a whole entity are very similar to the human brain.
		One problem: our brains are not doubling in size every 18 months.

	PetaHertz: What's up with that? (Site not responding. Last check: 2007-10-17)
		Hertz, as we all know, is a unit of frequency equal to one cycle per second named after Heinrich Rudolf Hertz - a German physicist who was the first man to produce electromagnetic waves artificially.
		PetaHertz is a unit of measure for very fast frequencies.

		Subject: Re: Terahertz, Petahertz, Exahertz, Zettahertz and Yottahertz
		1 Petahertz (1PHz) is in the ultraviolet range.
		If you transmit in some of the other bands you describe, you may find yourself attempting to modulate X-rays and "cosmic" rays.

	TrekWars - The Furry Conflict: Gamma Ray
		Gamma rays (often denoted by the Greek letter gamma) are an energetic form of electromagnetic radiation produced by nuclear or subatomic processes such as electron-position annihilation or cobalt-60 decay.
		The atmosphere of Class M planets, however, readily absorb large amounts of X-rays and gamma rays, making them largely opaque to these damagingly high frequency electromagnetic waves.
		Gamma rays are sometimes divided into subsets to designate different frequency ranges between 30 Petahertz and 60 Exahertz.

		The neurons in your brain, for their part, hum along at barely a kilohertz; thank the Lord for parallel processing.
		Dental X rays, at the other extreme, top a petahertz — a thousand trillion cycles per second.
		The potential number of frequencies is literally infinite, limited only by how finely your technology can parse the rainbow.

		* Sample rate = 10^17 = 100 petahertz = 0.1 exahertz.
		* Maximum frequency (two sinewaves in output array) = 25 petahertz = 12nm wavelength.
		* 25 petahertz = 2.5 x 10^16 Hz.

		They are talking about the science of photonics – which refers to carrying data, voice and video as light over fibre optic networks.
		These networks have astounding capacity – estimated to go up to almost Petahertz (10 to the power of 15)!
		Fibre optics will undoubtedly be the core of the Internetwork that spans the globe today.

	Maximum frequency of electrical pulses through wire?
		And How would someone say, produce a frequency of, say, a terahertz, or a petahertz in a wire?
		Parasitics definitely limits the frequency, as does speed of semiconductors.
		Without any real qualification to state so, having only some electronics background, I'd guess that Terahertz maybe, petahertz no way for traditional copper based chip technologies.

		Module 3 is the reactor chamber, containing 4 separate technologies that symbiotically enhance the others.
		The first of these was developed by the US military to sterilize the air of all bacteria and viruses in field surgical units under battlefield conditions by using electromagnetic radiation, with a frequency of 118 petahertz, which disrupts the DNA of all biological agents.
		This frequency, above the range of visible light and just below x-rays, possesses the unique property of being able to penetrate all cell walls and cell membranes and destroying the DNA of all living organisms.

	Naval Non-ionizing Radiation Health
		Non-ionizing radiation (NIR) refers to electromagnetic radiation (EMR) that does not have sufficient energy (about 34 electron volts or eV) to cause the breaking of the atomic electron bonds.
		The name generally applies to EMR that has wavelengths greater than 10 nanometers and a frequency greater than a PetaHertz (
		Although these waves cannot cause ionizations, they can cause biological damage through a variety of mechanisms.

	The Hindu : Sea change in supercomputing
		It uploads the results periodically to the main research website.Another ambitious project launched in February this year, by an American internet service provider, Juno Online, hopes that its 4 million subscribers will `donate' some PC time, to create a Virtual Supercomputer for biotechnology research.
		If indeed 4 million PCs share the work, this would theoretically create a virtual machine that could crash the `petahertz barrier' ie it would be faster than 1 petahertz 1 billion megahertz.
		That would make today's `Top 500' supercomputers look like bullock carts in line up of racing cars.

		But the free Internet service provider hopes its Virtual Supercomputer Project will help reverse its cash flow and keep e-mail free, while helping scientists search the human genome for disease-fighting proteins.
		Juno hopes about one-quarter of its 4.1 million active subscribers will donate some processing power to the project, creating the world's largest supercomputer and, perhaps, breaking the petahertz barrier by creating the aggregate computing power of 1 million gigahertz processors.
		But Juno Senior Vice President Gary Baker says if too few people sign up, members may be forced to join the project, conducted in concert with LaunchCyte, a Pittsburgh bioinformatics company.
