Mechanics is the area of physics concerned with the motions of macroscopic objects. Forces applied to objects result in displacements, or changes of an object's position relative to its environment; this branch of physics has its origins in Ancient Greece with the writings of Aristotle and Archimedes. During the early modern period, scientists such as Galileo and Newton laid the foundation for what is now known as classical mechanics, it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities less than the speed of light. It can be defined as a branch of science which deals with the motion of and forces on bodies not in the quantum realm; the field is yet less understood in terms of quantum theory. Classical mechanics came first and quantum mechanics is a comparatively recent development. Classical mechanics originated with Isaac Newton's laws of motion in Philosophiæ Naturalis Principia Mathematica. Both are held to constitute the most certain knowledge that exists about physical nature.
Classical mechanics has often been viewed as a model for other so-called exact sciences. Essential in this respect is the extensive use of mathematics in theories, as well as the decisive role played by experiment in generating and testing them. Quantum mechanics is of a bigger scope, as it encompasses classical mechanics as a sub-discipline which applies under certain restricted circumstances. According to the correspondence principle, there is no contradiction or conflict between the two subjects, each pertains to specific situations; the correspondence principle states that the behavior of systems described by quantum theories reproduces classical physics in the limit of large quantum numbers. Quantum mechanics has superseded classical mechanics at the foundation level and is indispensable for the explanation and prediction of processes at the molecular and sub-atomic level. However, for macroscopic processes classical mechanics is able to solve problems which are unmanageably difficult in quantum mechanics and hence remains useful and well used.
Modern descriptions of such behavior begin with a careful definition of such quantities as displacement, velocity, acceleration and force. Until about 400 years ago, motion was explained from a different point of view. For example, following the ideas of Greek philosopher and scientist Aristotle, scientists reasoned that a cannonball falls down because its natural position is in the Earth. Cited as father to modern science, Galileo brought together the ideas of other great thinkers of his time and began to calculate motion in terms of distance travelled from some starting position and the time that it took, he showed that the speed of falling objects increases during the time of their fall. This acceleration is the same for heavy objects as for light ones, provided air friction is discounted; the English mathematician and physicist Isaac Newton improved this analysis by defining force and mass and relating these to acceleration. For objects traveling at speeds close to the speed of light, Newton's laws were superseded by Albert Einstein’s theory of relativity.
For atomic and subatomic particles, Newton's laws were superseded by quantum theory. For everyday phenomena, Newton's three laws of motion remain the cornerstone of dynamics, the study of what causes motion. In analogy to the distinction between quantum and classical mechanics, Einstein's general and special theories of relativity have expanded the scope of Newton and Galileo's formulation of mechanics; the differences between relativistic and Newtonian mechanics become significant and dominant as the velocity of a massive body approaches the speed of light. For instance, in Newtonian mechanics, Newton's laws of motion specify that F = ma, whereas in relativistic mechanics and Lorentz transformations, which were first discovered by Hendrik Lorentz, F = γma. Relativistic corrections are needed for quantum mechanics, although general relativity has not been integrated; the two theories remain incompatible, a hurdle which must be overcome in developing a theory of everything. The main theory of mechanics in antiquity was Aristotelian mechanics.
A developer in this tradition is Hipparchus. In the Middle Ages, Aristotle's theories were criticized and modified by a number of figures, beginning with John Philoponus in the 6th century. A central problem was that of projectile motion, discussed by Hipparchus and Philoponus. Persian Islamic polymath Ibn Sīnā published his theory of motion in The Book of Healing, he said that an impetus is imparted to a projectile by the thrower, viewed it as persistent, requiring external forces such as air resistance to dissipate it. Ibn Sina made distinction between'force' and'inclination', argued that an object gained mayl when the object is in opposition to its natural motion. So he concluded that continuation of motion is attributed to the inclination, transferred to the object, that object will be in motion until the mayl is spent, he claimed that projectile in a vacuum would not stop unless it is acted upon. This conception of motion is consistent with Newton's first law of inertia. Which states that an ob
Waliszewski is a Polish surname, most prevalent in the Greater Poland, Łódź, Masovian and Kuyavian-Pomeranian voivodeships in central Poland and is present in the Polish diaspora. It was first recorded in 1397 and is of toponymic origin, deriving either from Waliszewice, two small villages with the name Waliszew or a third, now defunct Waliszew which separated into Waliszew Dworski and Stary Waliszew, small settlements in the Łódź and Masovian voivodeships; the stem of the toponym Waliszew is derived from the diminutive form Walisz of the old Polish male name Walisław/Wolisław. Notable people with the name Waliszewski include: Aleksandra Waliszewska, Polish painter, graphic artist and illustrator Kazimierz Waliszewski, Polish author of history Zygmunt Waliszewski, Polish painter
Parshuram Kund is a Hindu pilgrimage centre situated on the Brahmaputra plateau in the lower reaches of the Lohit River and 21 km north of Tezu in Lohit district of Arunachal Pradesh. Dedicated to sage Parshuram, the popular site attracts pilgrims from Nepal, from across India, from nearby states of Manipur and Assam. Over 70,000 devotees and sadhus take a holy dip in its water each year on the occasion of Makar Sankranti, in the month of January, it is a shrine of all-India importance located in the lower reaches of the Lohit River. Thousands of pilgrims visit the place in winter every year on the Makar Sankranti day for a holy dip in the sacred kund, believed to wash away one's sins. There is a mythological story behind this beautiful place, it is believed that Lord Parashuram the sixth incarnation of Lord Vishnu, on the orders of his father Rishi Jamadagni, beheaded his mother Renuka with his axe. Since he had committed one of the worst crimes of killing one's mother, the axe got stuck to his hand.
His father pleased with his obedience decided to give him a boon to which he asked for his mother to be restored back to life. After his mother was brought back to life the axe could not be removed from his hand; this was a reminder of the heinous crime. He repented for his crime and on taking the advice of eminent rishis of that time, he arrived at the banks of Lohit River to wash his hands in its pure waters, it was a way to cleanse him of all the sins. As soon as he dipped his hands into the waters the axe got detached and since the site where he washed his hands became a place of worship and came to be known by sadhus as Parashuram Kund. How far this story is credible is not known as not many have heard of it and neither has anyone come across it in the holy scriptures for Hindus such as the Vishnu Puran etc. There are many stories varying from region to region in India that describe the above incident and there are numerous temples dedicated to Lord Parashuram most of which are in Kerala.
But this place attracts many pilgrims from near and far and quite a few sanyasis reside here and take care of the temple, dedicated to Lord Parashuram. The site of the Parashuram Kund as established by the sadhu was in existence until the 1950 Assam earthquake that shook the whole of the North-East and the kund was covered. A strong current is now flowing over the original site of the kund but massive boulders have in a mysterious way embedded themselves in a circular formation in the river bed thus forming another kund in place of the old. Annual fair is held during Makara Sankranti, to which wild cows, rare fur-rugs and other curios are brought down by the mountain tribes. There are facilities for trekking from Tezu to glow lake which takes one day and river rafting and angling on the river Lohit; the nearest railway station is Tinsukia from. There are buses available from Sadiya; the nearest airports are Dibrugarh. There is no railway available to Parshuram Kund as of now. A survey of 122 km Rupai-Parshuram Kund broad gauge railway line was complete at the initiative of Arunachal Chamber of Commerce and Industries, while a preliminary engineering-traffic survey for the Pasighat-Tezu-Parsuram Kund was conducted by northeast frontier railways at the request of the state government.
The Charlotte Hornets are an American professional basketball team based in Charlotte, North Carolina. The Hornets compete in the National Basketball Association, as a member of the league's Eastern Conference Southeast Division; the team is owned by NBA Hall-of-Fame legend Michael Jordan, who acquired a controlling interest in the team in 2010. The Hornets play their home games at the Spectrum Center in Uptown Charlotte; the original Hornets franchise was established in 1988 as an expansion team, owned by George Shinn. In 2002, Shinn's franchise became the New Orleans Hornets. In 2004, the NBA established the Charlotte Bobcats, regarded as a new expansion team at the time. In 2013, the New Orleans franchise announced it would rebrand itself the New Orleans Pelicans returning the Hornets name and official history to Charlotte; the Bobcats were renamed the Charlotte Hornets for the 2014–15 season. In 1985, the NBA was planning to expand by three teams by the 1988–1989 season modified to include a total of four expansion teams.
George Shinn, an entrepreneur from Kannapolis, wanted to bring an NBA team to the Charlotte area, he assembled a group of prominent local businessmen to head the prospective franchise. The Charlotte area had long been a hotbed for college basketball. Charlotte was one of the fastest-growing cities in the United States, was one of the three in-state regional homes to the American Basketball Association's Carolina Cougars from 1969 to 1974. Despite doubt from critics, Shinn's ace in the hole was the Charlotte Coliseum, a state-of-the-art arena that would seat 24,000 spectators – the largest basketball-specific arena to serve as a full-time home for an NBA team. On April 5, 1987, then-NBA Commissioner David Stern called Shinn to tell him his group had been awarded the 24th NBA franchise, to begin play in 1988. Franchises were granted to Miami, Minneapolis-Saint Paul, Orlando; the new team was going to be called the Charlotte Spirit, but a name-the-team contest yielded "Hornets" as the winning choice.
The team received further attention when it chose teal as its primary color, setting off a sports fashion craze in the late 1980s and early 1990s. The team's uniforms, designed by international designer and North Carolina native Alexander Julian, featured a first for NBA uniforms—pin stripes. Similar designs by other teams followed. Shinn hired Carl Scheer as the team's first General Manager. Scheer preferred a roster of veteran players, hoping to put together a competitive team as soon as possible. Former college coach and veteran NBA assistant Dick Harter was hired as the team's first head coach. In 1988, the Hornets and the Miami Heat were part of the 1988 NBA Expansion Draft. Unlike many expansion franchises that invest in the future with a team composed of young players, Charlotte stocked its inaugural roster with several veterans in hopes of putting a competitive lineup on the court right away; the team had three draft picks at the 1988 NBA draft. The Hornets' first NBA game took place on November 4, 1988, at the Charlotte Coliseum, losing 133–93 to the Cleveland Cavaliers.
Four days the team notched its first-ever victory over the Los Angeles Clippers, 117–105. On December 23, 1988, the Hornets gave their fans something to cheer about, beating Michael Jordan and the Chicago Bulls 103–101 in Jordan's first return to North Carolina as a professional; the Hornets finished their inaugural season with a record of 20–62. Scheer left prior to the 1989–90 season. Despite initial concerns that the Coliseum was too big, the Hornets were a runaway hit, leading the NBA in attendance, a feat they would achieve seven more times in Charlotte; the Hornets would sell out 364 consecutive games. The Hornets' second season was a struggle from start to finish. Members of the team rebelled against Dick Harter's defense-oriented style, he was replaced mid-season by assistant Gene Littles following an 8–32 start. Despite the change, the team continued to struggle, finishing the season with a disappointing 19–63 record; the team showed improvement during the following season. They won eight of their first fifteen games, including a 120–105 victory over the Washington Bullets.
However, the team went cold. The Hornets, who hosted the 1991 NBA All-Star Game, finished with a 26–56 record. Despite the team's seven-game improvement over the previous season, Gene Littles was fired at the end of the season and replaced by general manager Allan Bristow. With the first pick in the 1991 NBA draft, the Hornets drafted power forward Larry Johnson from the University of Nevada, Las Vegas. Johnson had an impact season, finishing among the league leaders in points and rebounds, winning the 1992 NBA Rookie of the Year Award. Additionally, Guard Kendall Gill led the club in scoring; the team stayed in contention for a playoff spot until March, but finished the year with a 31–51 record. The Hornets were in the lottery again in 1992 and won the second overall pick in the draft, using it to select Georgetown center Alonzo Mourning. Charlotte now had two 20–10 threats in Johnson and Mourning, who with Kendall Gill, formed the league's top young trio; the team finished their fifth season at 44–38, their first-ever winning record and good enough for the first playoff berth in franchise history.
Finishing fifth in the Eastern Conference, the Hornets upset the Boston Celtics in the first round, with Mourning winning the series with a 20-footer in game four. However, the Hornets lacked the experience and depth to defeat the New York Knicks, falling in five games in the second round. The
Pat Pimm is a Canadian politician, elected as a BC Liberal Member of the Legislative Assembly of British Columbia in the 2009 provincial election, represented the riding of Peace River North. He has lived in Fort St. John, British Columbia and has a business background working at an instrumentation company that specializes in the oil and gas sector, he spent 12 years on the Fort St. John city council before his election to the Legislative Assembly. In the 39th Parliament of BC Pimm served on several committees and first became involved with the Executive Council in October 2010 when former B. C. Premier Gordon Campbell appointed Pimm as the Parliamentary Secretary for the Natural Gas Initiative under the Ministry of Energy; when Christy Clark became Premier of British Columbia in March 2011, she retained Pimm at the same position. Pimm was re-elected to his Peace River North riding in the 2013 provincial election and was appointed Minister of Agriculture on June 10, 2013 by Premier Clark, he served as Parliamentary Secretary for the Northeast and has served as chair of the Northern Caucus and two Select Standing Committees: Aboriginal Affairs and Finance and Government Services.
Pimm has served as a member of Treasury Board. A lifelong resident of the Peace River region, he served 12 years as councillor for the City of Fort St. John from 1993 to 2005. With 25 years experience in the oil and gas industry, he was co-chair of the BC Oil and Gas Conference in 2002 and 2005, bringing together industry stakeholders to identify further strategies and opportunities for economic development in British Columbia's northeast region, he has served on a variety of other local community boards and committees. Pat Pimm was raised in Fort St. John, he raised two daughters. In 2005 he remarried to another woman, who had two grown sons, he established a career at an instrumentation business, Alpha Controls Ltd. specializing in the oil and gas sector. He has been a volunteer coach for youth baseball and hockey, he spent 12 years on the Fort St. John city council, from 1993 to 2005. While on council he advocated for the regionalization of services and the creation of a regional municipality.
During a 2001 municipal referendum concerning a Fort St. John boundary expansion around a proposed manufacturing plant, Pimm threatened to resign his council seat if the referendum failed. While on council Pimm worked with the province and other municipalities in establishing the Fairshare grant program which redirected some oil and gas revenue to local governments in northeastern BC for use on infrastructure projects, he supported the BC Lottery Corporation locating a gaming centre in Fort St. John; the appointment of MLA Richard Neufeld to the federal Senate of Canada in December 2008 by Prime Minister Stephen Harper created an opening in the BC provincial Peace River North riding. Such an opening was rare as Neufeld had represented the riding since 1991 and by Tony Brummet for the 12 years prior to Neufeld. There were five candidates in the race for the BC Liberal Party nomination: Chetwynd mayor Evan Saugstad, Fort St. John councillors Lori Ackerman and Dan Davies, School District trustee Linda Sewell, Pat Pimm.
With 1,200 BC Liberal members eligible to vote, Pimm won in the third round of preferential voting in March. He was soon thrust into the provincial election where he faced Fort Nelson town councilor and NDP candidate Jackie Allen, former chief of the Fort Nelson First Nation and Green Party candidate Liz Logan, others. Pimm oriented his campaign around economic issues stating "The economy is the number one issue and everything else falls around the economy. You have to have a strong economy to have good health care, good education...." Pimm won the Peace River North riding with 43% of the vote and his party formed a majority government. As the 39th Parliament of British Columbia began, Pimm was not selected for the Executive Council by Premier Gordon Campbell. In the first two sessions Pimm was assigned to three parliamentary committees: the Select Standing Committee on Crown Corporations, the Select Standing Committee on Parliamentary Reform, Ethical Conduct, Standing Orders and Private Bills, the Select Standing Committee on Legislative Initiatives.
Once the Harmonized Sales Tax was introduced, Pimm became supportive of it, arguing that it would make BC business more competitive with Alberta, stating, "I think it's the strongest single thing for the economy of our area and the province in general." Pimm lobbied on behalf of the Peace River North to secure infrastructure grants for road construction and paving, recreation centre upgrades, Fort St. John sewerage expansion. Pimm made headlines across the province in November 2009 when he criticized the Canadian Charter of Rights and Freedoms during a speech in the Legislature, he questioned "who needs that Charter of Rights?" and stated "I just don’t think it’s a good document whatsoever myself." He called for a "Bill of Responsibilities" to be established. In 2010, as the petition to repeal the HST was successful in his riding, Pimm became one of 24 MLAs targeted for recall by Bill Vander Zalm's FightHST group. However, several months his name was removed from the list as the group prioritized candidates for recall campaigns.
In October, during Campbell's final cabinet shuffle before resigning, the post of Parliamentary Secretary for the Natural Gas Initiative was created for Pimm under the Ministry of Energy. In January 2011, with community opposition to a tra
