Jon Louis Bentley (born February 20, 1953) is an American computer scientist who is known for his contributions to computer programming, algorithms and data structure research.
47-660: Bentley received a B.S. in mathematical sciences from Stanford University in 1974. At this time he developed his most cited work, the heuristic-based partitioning algorithm k-d tree , published in 1975. He received a M.S. and PhD in 1976 from the University of North Carolina at Chapel Hill . While a student, he also held internships at the Xerox Palo Alto Research Center and Stanford Linear Accelerator Center . After receiving his Ph.D., he taught programming and computer architecture for six years as member of
94-481: A BSc (Hons). It could take from 4 to 6 years (8 to 12 periods) to complete, is also more specific and could be applied for Scientific Arts courses (like Engineering, Maths, Physics, etc.), somewhat is called Human Art courses in Brazil (like History, Portuguese and Literature and Lawyer studies for example) as well as for Health Arts (like Medicine, Nursery, Zootechnique, Veterinary and Biology for example). To be able to start
141-450: A direct correlation between reduced social mobility and differences unique to the Chilean higher education system. Non-science A non-science is an area of study that is not scientific, especially one that is not a natural science or a social science that is an object of scientific inquiry . In this model, history , art , and religion are all examples of non-sciences. Since
188-586: A master's degree (MSc) is also possible, which takes 3 to 5 periods more (1.5 to 2.5 years more). Commonly in British Commonwealth countries and Ireland graduands are admitted to the degree of Bachelor of Science after having completed a programme in one or more of the sciences. These programmes may take different lengths of time to complete. A Bachelor of Science receives the designation BSc for an ordinary degree and BSc (Hons) for an honours degree . In England, Wales and Northern Ireland an honours degree

282-402: A question as if it were a puzzle. Kuhn's view of science is also focused on the process of scientific inquiry, rather than the result. Boundary-work is the process of advocating for a desired outcome in the process of classifying fields of study that are near the borders. The rewards associated with winning a particular classification suggest that the boundary between science and non-science
329-462: A year compared to other institutions. In Chile , some undergraduate majors such as engineering and geology are designed as six-year programs. However, in practice it is not uncommon for students to complete such programs over the course of ten years, while studying full-time without leaves of absence. This is in part due to a strict grading system where the highest grade of a typical class can be as low as 60% (C-). There are studies that suggest
376-531: Is socially constructed and ideologically motivated rather than representing a stark natural difference between science and non-science. The belief that scientific knowledge (e.g., biology) is more valuable than other forms of knowledge (e.g., ethics) is called scientism . Non-science includes all areas of study that are not science. Non-science encompasses all of the humanities , including: The philosopher Martin Mahner proposed calling these academic fields
423-512: Is " Licenciado en Ciencias ", which can be obtained as a result of completing a 4–6 year program. However, in most cases, 4-year programs will grant a Bachelor of Applied Science (Spanish: "Licenciatura en Ciencias Aplicadas" ) degree, while other 4-year programs will not grant to an academic degree. Many universities in Europe are changing their systems into the BA/MA system and in doing so also offering
470-401: Is a broad concept that encompasses reliable knowledge without making a distinction between subject area. The Wissenschaft concept is more useful than the distinction between science and non-science in distinguishing between knowledge and pseudo-knowledge, as the errors made in all forms of pseudo-scholarship , from pseudohistory to pseudoscience , are similar. This Wissenschaft concept
517-445: Is an example of a field that borrows from both the natural sciences and history. Fields of inquiry may change status over time. For many centuries, alchemy was accepted as scientific: it produced some useful information, and it supported experiments and open inquiry in the pursuit of understanding the physical world. Since the 20th century, it has been considered a pseudoscience. Modern chemistry , which developed out of alchemy,

#1732890779968564-618: Is awarded for programs that generally last three to five years. The first university to admit a student to the degree of Bachelor of Science was the University of London in 1860. In the United States, the Lawrence Scientific School first conferred the degree in 1851, followed by the University of Michigan in 1855. Nathaniel Shaler , who was Harvard's Dean of Sciences, wrote in a private letter that "the degree of Bachelor of Science came to be introduced into our system through
611-518: Is considered a major natural science. Some philosophers, such as Paul Feyerabend , object to the effort to classify knowledge into science and non-science. The distinction is artificial, as there is little or nothing that ties together all of the bodies of knowledge that are called "sciences". Some systems of organizing knowledge separate systematic knowledge from non-systematic methods of knowing or learning something, such as personal experiences, intuition , and innate knowledge .

705-401: Is required to progress on to the stage of Doctor of Philosophy (PhD). In New Zealand, in some cases, the honours degree comprises an additional postgraduate qualification. In other cases, students with strong performance in their second or third year, are invited to extend their degree to an additional year, with a focus on research, granting access to doctoral programs. In South Africa,
752-409: Is targeted toward students intending to pursue graduate school or a profession in that discipline. The following are the subjects that, regardless of country, are offered in a BSc program: In some institutions, there are historical and traditional reasons that govern the granting of BS or BA degrees regardless of the disciplines offered. Georgetown University 's School of Foreign Service awards
799-428: Is typically completed over a three-year period, though there are a few intensified two-year courses (with less vacation time). Bachelor's degrees (without honours) were typically completed in two years for most of the twentieth century. In Scotland, where access to university is possible after one less year of secondary education, degree courses have a foundation year making the total course length four years. In Ireland,
846-761: Is usually a three-year graduate program in India offered by state and central universities . Some independent private colleges can also offer BS degrees with minimum changes in curriculum. B.Sc. is different from Bachelor of Engineering (B.E.) or Bachelor of Technology (B.Tech.) . Two exceptions are the B.Sc. (Research) course offered by the Indian Institute of Science , the BS degrees in Physics, Data Science (Online degree), Electronic systems (Online degree), Medical Sciences & Engineering offered by IIT Madras which lasts four years and
893-694: The Bachelor of Science in Foreign Service (BSFS) degrees to all of its undergraduates, although many students major in humanities-oriented fields such as international history or culture and politics.

1175-594: The parasciences , to distinguish them from disreputable forms of non-science, such as pseudoscience . Non-sciences offer information about the meaning of life , human values , the human condition , and ways of interacting with other people, including studies of cultures , morality and ethics . Philosophers disagree about whether areas of study involving abstract concepts , such as pure mathematics , are scientific or non-scientific. Interdisciplinary studies may cover knowledge-generating work that includes both scientific and non-scientific studies. Archaeology
1222-403: The 17th century, some writers have used the word science to exclude some areas of studies, such as the arts and the liberal arts . The word nonscience , to describe non-scientific academic disciplines, was first used in the middle of the 19th century. In some cases, it can be difficult to identify exact boundaries between science and non-science. The demarcation problem is the study of
1269-523: The BS-MS course offered by the IISERs , both of which provide more research and interdisciplinary emphasis. From session 2022–23, the University of Delhi implemented NEP 2020 under which a bachelor's degree became a 4-year degree with multiple exit and entry options. A student receives a B.Sc. (research) field of study or B.Sc. (honours) field of multidisciplinary studies after the 4th year. In Canada, Mexico, and
1316-491: The BSc is taken over three years, while the postgraduate BSc (Hons) entails an additional year of study. Admission to the honours degree is on the basis of a sufficiently high average in the BSc major; an honours degree is required for MSc level study, and admission to a doctorate is via the MSc. In Brazil , a Bachelor of Science degree is an undergraduate academic degree and is equivalent to
1363-676: The United States, it is most often a four-year undergraduate degree , typically in engineering , computer science , mathematics , economics , finance , business , or the natural sciences .

Algeria , Australia , Austria , Barbados , Belgium , Belize , Bosnia and Herzegovina (mostly three years, sometimes four), Cameroon , Canada (specifically Quebec ), Côte d'Ivoire , Croatia (mostly three years, sometimes four), Czech Republic (mostly three years, sometimes four), Denmark , England (three or four years with
1410-577: The arts and humanities. Northwestern University 's School of Communication grants the Bachelor of Science in Journalism degrees in all of its programs of study, including theater, dance, and radio/television/film. Meanwhile, the Oxbridge universities almost exclusively award the BA as a first degree. The decision to grant a BS or BA degree at some institutions also depends on the constituent colleges, even when

In Algeria , the student presents a thesis in front of a Jury at the end of the fifth year. Some universities in Canada (such as University of British Columbia and Vancouver Island University ) have most of their science and applied science students extend their degree by
1598-416: The difficulties in determining whether certain fields of study, near the boundaries of science and non-science, should be considered as one or the other. No single test has yet been devised that can clearly separate science from non-science, but some factors, taken as a whole and evaluated over time, are commonly used. In the view of Thomas Kuhn , these factors include the desire of scientists to investigate
1645-422: The end of a course and as a mandatory condition for its completion (and ultimately, to obtain a degree), students are compelled to produce an original research project related to their field. This project is usually referred to as a thesis (although the term actually corresponds to post-graduate studies). In Australia, the BSc is generally a three to four-year degree. An honours year or a master's by research degree

At CMU, his students included Brian Reid , John Ousterhout , Jeff Eppinger , Joshua Bloch , and James Gosling , and he was one of Charles Leiserson 's advisors. He published Writing efficient programs in 1982. In 1982, Bentley moved to the Computer Science Research Center at Bell Laboratories , where he
1739-445: The former BS was changed to BSc (Hons), which is awarded after four years. The BSc (Ord) is awarded after three years. Formerly at the University of Oxford , the degree of BSc was a postgraduate degree; this former degree, still actively granted, has since been renamed MSc. In Chile , the completion of a university program leads to an academic degree as well as a professional title. The academic degree equivalent to Bachelor of Science
1786-600: The full equivalent of a BSc or MSc (see Bologna Process ). Universities in the Czech Republic are changing their systems into the Bachelor of Science/Master of Science system and in doing so also offering the full equivalent of a BSc (Bc.) or MSc (Mgr./Ing.). In Germany, there are two kinds of universities: Universitäten and Fachhochschulen (which are also called University of Applied Sciences). Universitäten and Fachhochschulen – both also called Hochschulen - are legally equal, but Fachhochschulen have

Whether Bachelor of Science or Bachelor of Arts degrees are awarded in particular subjects varies between universities. For example, an economics student may graduate as a Bachelor of Arts in one university but as a Bachelor of Science in another, and occasionally, both options are offered. Some universities follow
1880-448: The last 2 to 3 years disciplines more related to the professional fields of that Bachelor of Science (for example Units Operations, Thermodynamics, Chemical Reactors, Industrial Processes, Kinetics for Chemical Engineering for example). Some disciplines are prerequisite to others and in some universities, the student is not allowed to course any discipline for the entire next period if he was unsuccessful in just one prerequisite discipline of
1927-425: The present period. Usually, the Bachelor of Science courses demand a one-year mandatory probation period by the end of the course (internship in the specific professional area, like a training period), followed by relatively elaborate written and oral evaluations. To get the certification as BSc, most universities require that the students achieve the accomplishment of 60% to 70% in all the "obligatory disciplines", plus

1974-708: The reputation of being more related to practice and have no legal right to offer PhD programmes. The BSc in Germany is equivalent to the BSc(Hons) in the United Kingdom. Many universities in German-speaking countries are changing their systems to the BA/MA system and in doing so also offering the full equivalent of a BSc. In Germany the BA normally lasts between three and four years (six to eight semesters) and between 180 and 240 ECTS must be earned. Bachelor of Science (B.Sc.)
2021-455: The same undergraduate degree in computer science can be an A.B. if taken at Harvard College or Harvard John A. Paulson School of Engineering and Applied Sciences , and an A.L.B. at Harvard Extension School . In Argentina most university degrees are given as a license in a discipline. They are specific to a field and awarded to students upon completion of a course of study which lasts at least four and usually five years. In most cases, at
