Nanoethics
Ethics of nanotechnology is the study of the ethical issues emerging from advances in nanotechnology and its impacts. According to Andrew Chen, ethical concerns about nanotechnologies should include the possibility of their military applications, the dangers posed by self-replicant nanomachines, and their use for surveillance monitoring and tracking. Risks to environment to public health are treated in a report from the Dutch National Institute for Public Health and the Environment as well as is a report of the European Environment Agency. Academic works on ethics of nanotechnology can be found in the journal Nanoethics. Guidelines According to the Markkula Center for Applied Ethics possible guidelines for an Ethics of nanotechnology could include: *Nanomachines should only be specialized, not for general purpose *Nanomachines should not be self replicating *Nanomachines should not be made to use an abundant natural compound as fuel *Nanomachines should be tagged so that they can ...

Ethics
Ethics is the philosophy, philosophical study of Morality, moral phenomena. Also called moral philosophy, it investigates Normativity, normative questions about what people ought to do or which behavior is morally right. Its main branches include normative ethics, applied ethics, and metaethics. Normative ethics aims to find general principles that govern how people should act. Applied ethics examines concrete ethical problems in real-life situations, such as abortion, treatment of animals, and Business ethics, business practices. Metaethics explores the underlying assumptions and concepts of ethics. It asks whether there are objective moral facts, how moral knowledge is possible, and how moral judgments motivate people. Influential normative theories are consequentialism, deontology, and virtue ethics. According to consequentialists, an act is right if it leads to the best consequences. Deontologists focus on acts themselves, saying that they must adhere to Duty, duties, like t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transhumanism
Transhumanism is a philosophical and intellectual movement that advocates the human enhancement, enhancement of the human condition by developing and making widely available new and future technologies that can greatly enhance longevity, cognition, and well-being. Transhumanist thinkers study the potential benefits and dangers of emerging technologies that could overcome fundamental human limitations, as well as the technoethics, ethics of using such technologies. Some transhumanists speculate that human beings may eventually be able to transform themselves into beings of such vastly greater abilities as to merit the label of posthuman#Transhumanism, posthuman beings. Another topic of transhumanist research is how to protect humanity against existential risks from Existential risk from artificial general intelligence, artificial general intelligence, asteroid impact, gray goo, high-energy particle collision experiments, natural or synthetic pandemic, and nuclear warfare.

Nanomaterials
Nanomaterials describe, in principle, chemical substances or materials of which a single unit is sized (in at least one dimension) between 1 and 100 nm (the usual definition of nanoscale). Nanomaterials research takes a materials science-based approach to nanotechnology, leveraging advances in materials metrology and synthesis which have been developed in support of microfabrication research. Materials with structure at the nanoscale often have unique optical, electronic, thermo-physical or mechanical properties. Nanomaterials are slowly becoming commercialized and beginning to emerge as commodities. Definition In ISO/TS 80004, ''nanomaterial'' is defined as the "material with any external dimension in the nanoscale or having internal structure or surface structure in the nanoscale", with ''nanoscale'' defined as the "length range approximately from 1 nm to 100 nm". This includes both ''nano-objects'', which are discrete pieces of material, and ''nanostructu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nanotoxicity
Nanotoxicology is the study of the toxicity of nanomaterials. Because of quantum size effects and large surface area to volume ratio, nanomaterials have unique properties compared with their larger counterparts that affect their toxicity. Of the possible hazards, inhalation exposure appears to present the most concern, with animal studies showing pulmonary effects such as inflammation, fibrosis, and carcinogenicity for some nanomaterials. Skin contact and ingestion exposure are also a concern. Background Nanomaterials have at least one primary dimension of less than 100 nanometers, and often have properties different from those of their bulk components that are technologically useful. Because nanotechnology is a recent development, the health and safety effects of exposures to nanomaterials, and what levels of exposure may be acceptable, is not yet fully understood. Nanoparticles can be divided into combustion-derived nanoparticles (like diesel soot), manufactured nanoparticl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molecular Manufacturing
A molecular assembler, as defined by K. Eric Drexler, is a "proposed device able to guide chemical reactions by positioning reactive molecules with atomic precision". A molecular assembler is a molecular machine. Some biological molecules such as ribosomes fit this definition as biological machines. This is because they receive instructions from messenger RNA and then assemble specific sequences of amino acids to construct protein molecules. History Beginning in 2007, the British Engineering and Physical Sciences Research Council has funded development of ribosome-like molecular assemblers. Clearly, molecular assemblers are possible in this limited sense. A technology roadmap project, led by the Battelle Memorial Institute and hosted by several U.S. National Laboratories has explored a range of atomically precise fabrication technologies, including both early-generation and longer-term prospects for programmable molecular assembly; the report was released in December, 2007. ...

Nanotechnology
Nanotechnology is the manipulation of matter with at least one dimension sized from 1 to 100 nanometers (nm). At this scale, commonly known as the nanoscale, surface area and quantum mechanical effects become important in describing properties of matter. This definition of nanotechnology includes all types of research and technologies that deal with these special properties. It is common to see the plural form "nanotechnologies" as well as "nanoscale technologies" to refer to research and applications whose common trait is scale. An earlier understanding of nanotechnology referred to the particular technological goal of precisely manipulating atoms and molecules for fabricating macroscale products, now referred to as molecular nanotechnology. Nanotechnology defined by scale includes fields of science such as surface science, organic chemistry, molecular biology, semiconductor physics, energy storage, engineering, microfabrication, and molecular engineering.

Steven Umbrello
Stephen or Steven is an English first name. It is particularly significant to Christians, as it belonged to Saint Stephen ( ), an early disciple and deacon who, according to the Book of Acts, was stoned to death; he is widely regarded as the first martyr (or "protomartyr") of the Christian Church. The name, in both the forms Stephen and Steven, is often shortened to Steve or Stevie. In English, the female version of the name is Stephanie. Many surnames are derived from the first name, including Stephens, Stevens, Stephenson, and Stevenson, all of which mean "Stephen's (son)". In modern times the name has sometimes been given with intentionally non-standard spelling, such as Stevan or Stevon. A common variant of the name used in English is Stephan ( ); related names that have found some currency or significance in English include Stefan (pronounced or in English), Esteban (often pronounced ), and the Shakespearean Stephano ( ).

There's Plenty Of Room At The Bottom
"There's Plenty of Room at the Bottom: An Invitation to Enter a New Field of Physics" was a lecture given by physicist Richard Feynman at the annual American Physical Society meeting at Caltech on December 29, 1959. Feynman considered the possibility of direct manipulation of individual atoms as a more robust form of synthetic chemistry than those used at the time. Versions of the talk were reprinted in a few popular magazines, but it went largely unnoticed until the 1980s. The title references the popular quote ''"There is always room at the top."'' attributed to Daniel Webster (who is thought to have said this phrase in response to warnings against becoming a lawyer, which was seen as an oversaturated field in the 19th century). Conception Feynman considered some ramifications of a general ability to manipulate matter on an atomic scale. He was particularly interested in the possibilities of denser computer circuitry and microscopes that could see things much smaller than is po ...

Surely You're Joking, Mr
''Heart and Soul'' is a 1994 album by the British pop group Five Star. It was the group's first album for three years, released independently on their own label, Tent Records. It was first released in the US in 1994, and released in the UK in 1995 featuring completely different artwork from the US version. There were three singles released from the album: I Love You (For Sentimental Reasons), I Give You Give, and Surely. Promotional videos were produced for the first two singles; I Love You (For Sentimental Reasons) was directed by Malcolm-Jamal Warner. It was commercially unsuccessful in both countries. Release Five Stars released "Surely" in 1995 as a single taken from ''Heart and Soul''. The single was a U.S. only release, available in the UK as an import. Although it missed the ''Billboard'' Hot 100 chart, it peaked at number 125 in October of that year (see 1995 in music This is a list of notable events in music that took place in the year 1995.

Richard Feynman
Richard Phillips Feynman (; May 11, 1918 – February 15, 1988) was an American theoretical physicist. He is best known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, the physics of the superfluidity of supercooled liquid helium, and in particle physics, for which he proposed the parton model. For his contributions to the development of quantum electrodynamics, Feynman received the Nobel Prize in Physics in 1965 jointly with Julian Schwinger and Shin'ichirō Tomonaga. Feynman developed a pictorial representation scheme for the mathematical expressions describing the behavior of subatomic particles, which later became known as Feynman diagrams and is widely used. During his lifetime, Feynman became one of the best-known scientists in the world. In a 1999 poll of 130 leading physicists worldwide by the British journal ''Physics World'', he was ranked the seventh-greatest physicist of all time. He assisted in the Manhatt ...
