Information:  - A research university is a university that expects all its tenured and tenure-track faculty to continuously engage in research, as opposed to merely requiring it as a condition of an initial appointment or tenure. Such universities can be recognized by their strong focus on innovative research and the prestige of their brand names. On the one hand, research universities strive to recruit faculty who are the most brilliant minds in their disciplines in the world, and their students enjoy the opportunity to learn from such experts. On the other hand, new students are often disappointed to realize their undergraduate courses at research universities are overly academic and fail to provide vocational training with immediate "real world" applications; but many employers value degrees from research universities because they know that such coursework develops fundamental skills like critical thinking.   - Biological Physics: Energy, Information, Life: With new art by David Goodsell is a book by Philip Nelson, illustrated by David Goodsell. This printing, the fifth, is published by W. H. Freeman in late 2013. It is a work on biology with an emphasis on the application of physical principles.  - The Max Delbruck Prize, formerly known as the Biological physics prize, is awarded by the Division of Biological Physics of the American Physical Society, to recognize and encourage outstanding achievement in biological physics research. The prize was established in 1981, and renamed for Max Delbrück in 2006. The award consists of $10,000, an allowance for travel to the meeting where the prize is awarded, and a certificate. It was presented biennially in even-numbered years until 2014, and will be presented annually starting 2015.   - Biophysics or biological physics is an interdisciplinary science that applies the approaches and methods of physics to study biological systems. Biophysics covers all scales of biological organization, from molecular to organismic and populations. Biophysical research shares significant overlap with biochemistry, physical chemistry, nanotechnology, bioengineering, computational biology, biomechanics and systems biology.  - The Biophysical Society is an international scientific society that exists to encourage the development and dissemination of knowledge in biophysics. Founded in 1958, the society currently consists of over 9,000 researchers in academia, government, and industry. Although the Society is based in the United States, it is an international organization. Overseas members currently comprise over one third of the total.  - The Rowland Institute for Science was founded by Edwin H. Land, founder of Polaroid Corporation, as a nonprofit basic research organization in 1980. It is named for the first head of the American Physical Society, Henry Augustus Rowland. The Rowland is dedicated to experimental science across a wide range of disciplines. Research subjects at the institute includes chemistry, physics and biology, and focuses on interdisciplinary work.  - Dr. Steven M. Block ( born 1952 ) is a professor at Stanford University with a joint appointment in the departments of Biological Sciences and Applied Physics .

Work in his lab has led to the direct observation of the 8 nm steps taken by kinesin and the sub-nanometer stepping motions of RNA polymerase on a DNA template . While consulting for the United States government through JASON , Block has researched the many threats associated with bioterrorism and headed influential studies on how advances in genetic engineering have impacted biological warfare .  - The Ivy League is a collegiate athletic conference comprising sports teams from eight private institutions of higher education in the Northeastern United States. The conference name is also commonly used to refer to those eight schools as a group beyond the sports context. The eight institutions are Brown University, Columbia University, Cornell University, Dartmouth College, Harvard University, the University of Pennsylvania, Princeton University, and Yale University. The term "Ivy League" has connotations of academic excellence, selectivity in admissions, and social elitism.  - The American Institute of Physics (AIP) promotes science, the profession of physics, publishes physics journals, and produces publications for scientific and engineering societies. The AIP is made up of various member societies. Its corporate headquarters are at the American Center for Physics in College Park, Maryland, but the institute also has offices in Melville, New York and Beijing.  - Industry is the production of goods or related services within an economy. The major source of revenue of a group or company is the indicator of its relevant industry. When a large group has multiple sources of revenue generation, it is considered to be working in different industries. Manufacturing industry became a key sector of production and labour in European and North American countries during the Industrial Revolution, upsetting previous mercantile and feudal economies. This came through many successive rapid advances in technology, such as the production of steel and coal.  - San Francisco (SF) (Spanish for Saint Francis) officially the City and County of San Francisco, is the cultural, commercial, and financial center of Northern California. It is the birthplace of the United Nations. Located at the north end of the San Francisco Peninsula, San Francisco is about in area, making it the smallest countyand the only consolidated city-countywithin the state of California. With a density of about 18,451 people per square mile (7,124 people per km), San Francisco is the most densely settled large city (population greater than 200,000) in California and the second-most densely populated major city in the United States after New York City. San Francisco is the fourth-most populous city in California, after Los Angeles, San Diego, and San Jose, and the 13th-most populous city in the United Stateswith a census-estimated 2015 population of 864,816. The city and its surrounding areas are known as the San Francisco Bay Area, and are a part of the larger OMB-designated San Jose-San Francisco-Oakland combined statistical area, the fifth most populous in the nation with an estimated population of 8.7 million.  - The American Revolution was a political upheaval that took place between 1765 and 1783 during which colonists in the Thirteen American Colonies rejected the British monarchy and aristocracy, overthrew the authority of Great Britain, and founded the United States of America.  - In biology, motility is the ability to move spontaneously and actively, consuming energy in the process. Motility is genetically determined (see genetic determinism) but may be affected by environmental factors. For instance, muscles give animals motility but the consumption of hydrogen cyanide (the environmental factor in this case) would adversely affect muscle physiology causing them to stiffen leading to rigor mortis. Most animals are motile but the term applies to unicellular and simple multicellular organisms, as well as to some mechanisms of fluid flow in multicellular organs, in addition to animal locomotion. Motile marine animals are commonly called free-swimming.  - Physical Review is an American peer-reviewed scientific journal established in 1893 by Edward Nichols. It publishes original research as well as scientific and literature reviews on all aspects of physics. It is published by the American Physical Society (APS). The journal is in its third series, and is split in several sub-journals each covering a particular field of physics. It has a sister journal, "Physical Review Letters", which publishes shorter articles of broader interest.  - Henry Augustus Rowland (November 27, 1848  April 16, 1901) was an American physicist. Between 1899 and 1901 he served as the first president of the American Physical Society. He is remembered today particularly for the high quality of the diffraction gratings he made and for the work he did with them on the solar spectrum.  - John Adams (October 30 [O.S. October 19] 1735  July 4, 1826) was an American patriot who served as the second President of the United States (17971801) and the first Vice President (178997). He was a lawyer, diplomat, statesman, political theorist, and, as a Founding Father, a leader of the movement for American independence from Great Britain. He was also a dedicated diarist and correspondent, particularly with his wife and closest advisor Abigail.  - The American Physical Society (APS) is the world's second largest organization of physicists. The Society publishes more than a dozen scientific journals, including the prestigious "Physical Review" and "Physical Review Letters", and organizes more than twenty science meetings each year. APS is a member society of the American Institute of Physics.  - The United States Constitution is the supreme law of the United States of America. The Constitution, originally comprising seven articles, delineates the national frame of government. Its first three articles entrench the doctrine of the separation of powers, whereby the federal government is divided into three branches: the legislative, consisting of the bicameral Congress; the executive, consisting of the President; and the judicial, consisting of the Supreme Court and other federal courts. Articles Four, Five and Six entrench concepts of federalism, describing the rights and responsibilities of state governments and of the states in relationship to the federal government. Article Seven establishes the procedure subsequently used by the thirteen States to ratify it.  - Edwin Herbert Land, ForMemRS, FRPS, Hon.MRI (May 7, 1909  March 1, 1991) was an American scientist and inventor, best known as the co-founder of the Polaroid Corporation. Among other things, he invented inexpensive filters for polarizing light, a practical system of in-camera instant photography, and his retinex theory of color vision. His Polaroid instant camera, which went on sale in late 1948, made it possible for a picture to be taken and developed in 60 seconds or less.  - Physical Review Letters (PRL), established in 1958, is a peer-reviewed, scientific journal that is published 52 times per year by the American Physical Society. As also confirmed by various measurement standards, which include the "Journal Citation Reports" impact factor and the journal h-index proposed by Google Scholar, many physicists and other scientists consider "Physical Review Letters" one of the most prestigious journals in the field of physics.  - James Bowdoin II (August 7, 1726  November 6, 1790) was an American political and intellectual leader from Boston, Massachusetts, during the American Revolution and the following decade. He initially gained fame and influence as a wealthy merchant. He served in both branches of the Massachusetts General Court from the 1750s to the 1770s. Although he was initially supportive of the royal governors, he opposed British colonial policy and eventually became an influential advocate of independence. He authored a highly political report on the 1770 Boston Massacre that has been described by historian Francis Walett as one of the most influential pieces of writing that shaped public opinion in the colonies.  - Howard Curtis Berg (born 1934) is the Herchel Smith Professor of Physics and Professor of Molecular and Cellular Biology at Harvard University, where he teaches biophysics and studies the motility of the bacterium "Escherichia coli (E. coli)".  - The American Academy of Arts and Sciences, frequently known as the American Academy, is one of the oldest and most prestigious honorary societies and a leading center for policy research in the United States. Election to the Academy is considered one of the nation's highest honors since its founding during the American Revolution by John Adams, John Hancock, James Bowdoin, and other scholar-patriots who contributed prominently to the establishment of the new nation, its government, and the United States Constitution.  - Harvard University is a private Ivy League research university in Cambridge, Massachusetts, established in 1636, whose history, influence, and wealth have made it one of the world's most prestigious universities.  - Princeton University is a private Ivy League research university in Princeton, New Jersey, United States.  - John Hancock (October 8, 1793) was an American merchant, statesman, and prominent Patriot of the American Revolution. He served as president of the Second Continental Congress and was the first and third Governor of the Commonwealth of Massachusetts. He is remembered for his large and stylish signature on the United States Declaration of Independence, so much so that the term "John Hancock" has become, in the United States, a synonym for a signature.  - Max Ludwig Henning Delbrück, ForMemRS (September 4, 1906  March 9, 1981), a GermanAmerican biophysicist, helped launch the molecular biology research program in the late 1930s. He stimulated physical scientists' interest into biology, especially as to basic research to physically explain genes, mysterious at the time. Formed in 1945 and led by Delbrück along with Salvador Luria and Alfred Hershey, the Phage Group made substantial headway unraveling important aspects of genetics. The three shared the 1969 Nobel Prize in Physiology or Medicine "for their discoveries concerning the replication mechanism and the genetic structure of viruses". He was the first physicist to predict what is now called Delbrück scattering.  - Stanford University, officially Leland Stanford Junior University, is a private research university in Stanford, California, adjacent to Palo Alto and between San Jose and San Francisco. Its campus is one of the largest in the United States. Stanford also has land and facilities elsewhere.
