Biotechnology ... For thousands of years, humans have used selective breeding to improve production of crops and livestock to use them for food. In selective breeding, organisms with desirable characteristics are mated to produce offspring with the same characteristics...

List Of Nanotechnology Applications ... The name atom comes from the Greek ἄτομος (atomos, "indivisible") from ἀ- (a-, "not") and τέμνω (temnō, "I cut"), which means uncuttable, or indivisible, something that cannot be divided further. The concept of an atom as an indivisible component of matter was first proposed by early Indian and Greek philosophers...

Education In Pakistan ... The education system in Pakistan is generally divided into five levels: primary (grades one through five); middle (grades six through eight); high (grades nine and ten, leading to the Secondary School Certificate or SSC); intermediate (grades eleven and twelve, leading to a Higher Secondary (School) Certificate or HSC); and university programs leading to undergraduate and graduate degrees. The literacy rate ranges from 37% in Islamabad to 20% in the Kohlu District...

Molecular Nanotechnology ... A roadmap for the development of MNT is an objective of a broadly based technology project led by Battelle (the manager of several U. S. National Laboratories) and the Foresight Institute...

Moon Rock ... Rocks collected from the Moon have been measured by radiometric dating techniques. They range in age from about 3.16 billion years old for the basaltic samples derived from the lunar maria, up to about 4.5 billion years old for rocks derived from the highlands...

Specialty (medicine) ... The aim of astronomy is to understand the physics and chemistry from the laboratory that is behind cosmic events so as to enrich our understanding of the cosmos and of these sciences as well... Integrating astronomy and chemistry Astrochemistry, the overlap of the disciplines of astronomy and chemistry, is the study of the abundance and reactions of chemical elements and molecules in space, and their interaction with radiation...

Cybernetics ... Much of our understanding of fundamental chemistry evolved from ore smelting and refining, with De Re Metallica being the leading chemistry text for 180 years...

Graph Theory ... The graphs studied in graph theory should not be confused with the graphs of functions or other kinds of graphs. Refer to the glossary of graph theory for basic definitions in graph theory...

Evolution ... Life on Earth originated and then evolved from a universal common ancestor approximately 3.7 billion years ago. Repeated speciation and the divergence of life can be inferred from shared sets of biochemical and morphological traits, or by shared DNA sequences...

Nanotechnology ... Nanotechnology is very diverse, ranging from extensions of conventional device physics to completely new approaches based upon molecular self-assembly, from developing new materials with dimensions on the nanoscale to direct control of matter on the atomic scale. Nanotechnology entails the application of fields of science as diverse as surface science, organic chemistry, molecular biology, semiconductor physics, microfabrication, etc...

History Of Chemistry ... However, by performing experiments and recording the results the alchemist set the stage for modern chemistry... This distinction begins to emerge when a clear differentiation was made between chemistry and alchemy by Robert Boyle in his work The Sceptical Chymist (1661)... Chemistry then becomes a full-fledged science when Antoine Lavoisier develops his law of conservation of mass, which demands careful measurements and quantitative observations of chemical phenomena...

History Of Nanotechnology ... However, there exists no formal criteria for when educational programs and scholarly journals form an academic discipline. A huge difference exists between, on the one hand, well established disciplines that exist in almost all universities all over the world, have a long history and a well established set of journals and conferences, and, on the other hand, suggestions for new fields supported only by few universities and publications...

Earth Science ... Beneath the Earth's crust lies the mantle which is heated by the radioactive decay of heavy elements. The mantle is not quite solid and consists of magma which is in a state of semi-perpetual convection...

Timeline Of Chemistry ... Early ideas that later became incorporated into the modern science of chemistry come from two main sources...

Theoretical Astronomy ... Buckyballs can "interrupt" the allergy/immune response by preventing mast cells (which cause allergic response) from releasing histamine into the blood and tissues, by binding to free radicals "dramatically better than any anti-oxidant currently available, such as vitamin E". Tissue engineering Nanotechnology can help reproduce or repair damaged tissue...

Nobel Prize In Chemistry ... According to Nobel's will, The Royal Swedish Academy of sciences were to award the Prize in Chemistry...

Astronomy ... Astronomy is one of the oldest sciences. Prehistoric cultures left behind astronomical artifacts such as the Egyptian monuments, Nubian monuments and Stonehenge, and early civilizations such as the Babylonians, Greeks, Chinese, Indians, Iranians and Maya performed methodical observations of the night sky...

Atom ... The mathematical formulations of quantum mechanics are abstract. A mathematical function called the wavefunction provides information about the probability amplitude of position, momentum, and other physical properties of a particle...

Engineering ... The American Engineers' Council for Professional Development (ECPD, the predecessor of ABET) has defined "engineering" as: The creative application of scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination; or to construct or operate the same with full cognizance of their design; or to forecast their behavior under specific operating conditions; all as respects an intended function, economics of operation and safety to life and property.. ...

Quantum Mechanics ... After Feynman's death, scholars studying the historical development of nanotechnology have concluded that his actual role in catalyzing nanotechnology research was limited, based on recollections from many of the people active in the nascent field in the 1980s and 1990s. Chris Toumey, a cultural anthropologist at the University of South Carolina, found that the published versions of Feynman’s talk had a negligible influence in the twenty years after it was first published, as measured by citations in the scientific literature, and not much more influence in the decade after the Scanning Tunneling Microscope was invented in 1981...
