  • The first law of thermodynamics gives the quantiative relations between the internal energy of a system and the quantities of heat and work that the system exchange with surroundings. It express the conservation of energy. The first law of thermodynamics is true, but not enough ! Why ? Many thermodynamic processes which don’t violate the 1st law, but don’t happen in nature !

  • The rate of energy conversion or transmission (i.e. power) is related to the physical quantities such as force, speed, voltage, current, etc.For mechanical system, rate of energy transfer (i.e., power) to an object is the product of the force (F in Newton) and the speed (S in meter/sec) of the point where the force is applied.Q1. A person pushes an out-of-gas car with a force of 100 Newton (about 22.5 lb of force) to maintain a speed of 0.2 m/s. It took him 10 minutes to get to the nearest gas station. How much energy did this person use to do this work?...

  • 21 Unit Two PHYSICS Physics is the major science dealing with the fundamental constituents of the universe, the forces they exert on one another, and the results produced by these forces. Sometimes in modern physics a more sophisticated approach is taken that incorporates elements of the three areas listed above; it relates to the laws of symmetry and conservation, such as those pertaining to energy, momentum, charge, and parity. Physics is closely related to the other natural sciences and, in a sense, encompasses them. ...

  • These curriculum materials explore the cultural and artistic life in Pompeii and other towns around the Bay of Naples in the centuries leading up to the eruption of Vesuvius in the year 79. Two works of art, the mosaic Plato’s Academy (1st century BC–1st century AD) and the fresco Garden Scene (1st century BC–1st century AD), are examples of the embellishments applied to the gardens and interiors of Pompeian villas. A marble sculpture of the goddess Aphrodite from the early first century reflects the Roman interest in Greek mythology, art forms, and styles.

  • There is a basic law in thermodynamics; the law of conservation of energy, which states that energy may neither be created nor destroyed just can be transformed. Nature is an expert using this physics fundamental law favouring life and evolution of species all around the planet, it can be said that we are accustomed to live under this law that we do not pay attention to its existence and how it influence our lives.

  • I have tried to write a non-technical tour through the principles of physics. The theme running through this tour is that progress has often consisted in uncovering “hidden unities”. Let me explain what I mean by this phrase, taking the example (from Chapter 3) of electricity and magnetism. The unity here is hidden, because at first sight there seemed to be no connection between the two.

  • The teaching of constitutional law in American law schools focuses primarily—in fact, almost exclusively—on decisions rendered by the United States Supreme Court interpreting the Federal Constitution. For teachers of constitutional law who believe that equality and liberty are quintessential to a free society, this has come to be a disheartening affair, as the Supreme Court of the United States has become increasingly conservative and antipathetic, if not hostile, to the recognition of individual rights....

  • This is a short book, but it took a long time to write. In two previous books, Beyond All Reason and Desperately Seeking Certainty, we criticized some currently popular theories like originalism, the view (held by many conservative constitutional scholars) that the Constitution’s meaning is fi xed by the history of its creation. We also criticized theories of leading scholars at the other end of the ideological spectrum.

  • Medical and social statistics present the alarming reality that one in four people will suffer from mental illness at some point in their lives. Yet, in most countries, mental health is one of the least cared about issues. Korea is no exception. Here people with mental disorders have been subject to prejudice, stigma, discrimination and marginalization in all aspects of their social lives. Korean legal schemes and practices reveal a grave injustice in the treatment of patients and the administration of the mental health system.

  • The exchange is offered at market value, so current debt holders will experience a “haircut” from par value, and thus the exchange does not involve a “bailout.” However, present holders of sovereign debt will be exchanging low quality bonds with limited liquidity, for higher quality bonds with greater liquidity. Debt holders not accepting the exchange will be at risk of a forced restructuring at a later date at terms less favorable.

  • In July of 1994, Comet Shoemaker-Levy struck the planet Jupiter, depositing 7 × 1022 joules of energy, and incidentally giving rise to a series of Hollywood movies in which our own planet is threatened by an impact by a comet or asteroid. There is evidence that such an impact caused the extinction of the dinosaurs. Left: Jupiter’s gravitational force on the near side of the comet was greater than on the far side, and this difference in force tore up the comet into a string of fragments.

  • By writing this monograph, I would like first to provide a useful gathering of some knowledge that everybody involved in the numerical simulation of hyperbolic conservation laws could have learned in journals, in conferences communications, or simply by discussing with researchers or engineers. Most of the notions discussed along the chapters are indeed either extracted from journal articles, or are natural extensions of basic ideas introduced in these articles.

  • This book collects the lecture notes of two courses and one mini-course held in a winter school in Bologna in January 2005. The aim of this school was to popularize techniques of geometric measure theory among researchers and PhD students in hyperbolic differential equations. Though initially developed in the context of the calculus of variations, many of these techniques have proved to be quite powerful for the treatment of some hyperbolic problems.
