"We do know that whatever computing device we use will be far more powerful than the computers we use today by mid-century, just as today's machines greatly overshadow their predecessors." Using quantum computers could make computers faster and more powerful.

" Quantum "processors" could possibly one day replace silicon chips, just as the transistor replaced the vacuum tube." This is an example of how technology has changed-a comparison of the past to a comparison of the future.

"Graphene is made of a single layer of carbon atoms that are bonded together in a repeating pattern of hexagons. Graphene is one million times thinner than paper; so thin that it is actually considered two dimensional" The definition of what graphene really is.

"Ever since Gordon Moore made his famous "Moore's Law" prediction, stating that the number of transistors on a semiconductor application would double every couple of years, the industry has seen fit to beat that trend" The definition of what Moore's law really is.

"The "nanowires" is another alternative of the post silicon era, but there are many issues such as connecting them to the rest of the transistor, improving the semiconductor property, and ensuring the nanotubes are sized and positioned correctly. " Nanowires might be one of the alternatives of replacing silicon.

""In about ten years or so, we will see the collapse of Moore's Law. In fact, already, already we see a slowing down of Moore's Law," Moore's law will eventually collapse in the future.

"Nanotechnology is being applied to cancer in two broad areas: the development of nanovectors, such as nanoparticles, which can be loaded with drugs or imaging agents and then targeted to tumours, and high-throughput nanosensor devices for detecting the biological signatures of cancer. Combined, such technologies could lead to earlier diagnosis and better treatment for patients with cancer." Nanotechnology can also help see cancer in its earlier stages to help stop it from spreading.

"But nanotechnologists think they have an answer for treatment as well, and it comes in the form of targeted drug therapies. If scientists can load their cancer-detecting gold nanoparticles with anticancer drugs, they could attack the cancer exactly where it lives. Such a treatment means fewer side effects and less medication used. Nanoparticles also carry the potential for targeted and time-release drugs. A potent dose of drugs could be delivered to a specific area but engineered to release over a planned period to ensure maximum effectiveness and the patient's safety." Nanotechnology can be a better, more efficient way of getting rid of cancer cells.

"1. (Atomic Physics) a theory concerning the behaviour of physical systems based on Planck's idea that they can only possess certain properties, such as energy and angular momentum, in discrete amounts (quanta). The theory later developed in several equivalent mathematical forms based on De Broglie's theory and on the Heisenberg uncertainty principle" The definition of what the quantum theory is- only physical systems can possess certain properties.

"Nanotechnology (sometimes shortened to "nanotech") is the manipulation of matter on an atomic, molecular, and supramolecular scale" Nanotechnology is really a manipulation-nanotechnology doesn't happen naturally.

"A basic definition: Nanotechnology is the engineering of functional systems at the molecular scale. This covers both current work and concepts that are more advanced. In its original sense, 'nanotechnology' refers to the projected ability to construct items from the bottom up, using techniques and tools being developed today to make complete, high performance products." This is the definition of what nanotechnology is-building something from almost nothing.

"In order to understand the unusual world of nanotechnology, we need to get an idea of the units of measure involved. A centimeter is one-hundredth of a meter, a millimeter is one-thousandth of a meter, and a micrometer is one-millionth of a meter, but all of these are still huge compared to the nanoscale. A nanometer (nm) is one-billionth of a meter, smaller than the wavelength of visible light and a hundred-thousandth the width of a human hair [source: Berkeley Lab]. As small as a nanometer is, it's still large compared to the atomic scale. An atom has a diameter of about 0.1 nm. An atom's nucleus is much smaller -- about 0.00001 nm. Atoms are the building blocks for all matter in our universe. You and everything around you are made of atoms. Nature has perfected the science of manufacturing matter molecularly. For instance, our bodies are assembled in a specific manner from millions of living cells. Cells are nature's nanomachines. At the atomic scale, elements are at their most basic level. On the nanoscale, we can potentially put these atoms together to make almost anything" Nanotechnology is measured in a nanometer, which is one-billionth of a meter. Nanotechnology is extremely small, and can help create something from something not seen with human eye.
