[The Whale Capitals]( Dear Reader, If you have any money in US dollars, [click here now and see why you must move your cash before January 31st.]( Treasury Secretary Janet Yellen recently admitted that nations around the world will continue to dump the US dollar⦠Electricity, phenomenon associated with stationary or moving electric charges. Electric charge is a fundamental property of matter and is borne by elementary particles. In electricity the particle involved is the electron, which carries a charge designated, by convention, as negative. Thus, the various manifestations of electricity are the result of the accumulation or motion of numbers of electrons.Electrostatics is the study of electromagnetic phenomena that occur when there are no moving chargesâi.e., after a static equilibrium has been established. Charges reach their equilibrium positions rapidly because the electric force is extremely strong. The mathematical methods of electrostatics make it possible to calculate the distributions of the electric field and of the electric potential from a known configuration of charges, conductors, and insulators. Conversely, given a set of conductors with known potentials, it is possible to calculate electric fields in regions between the conductors and to determine the charge distribution on the surface of the conductors. The electric energy of a set of charges at rest can be viewed from the standpoint of the work required to assemble the charges; alternatively, the energy also can be considered to reside in the electric field produced by this assembly of charges. Finally, energy can be stored in a capacitor; the energy required to charge such a device is stored in it as electrostatic energy of the electric field.Static electricity is a familiar electric phenomenon in which charged particles are transferred from one body to another. For example, if two objects are rubbed together, especially if the objects are insulators and the surrounding air is dry, the objects acquire equal and opposite charges and an attractive force develops between them. The object that loses electrons becomes positively charged, and the other becomes negatively charged. The force is simply the attraction between charges of opposite sign. The properties of this force were described above; they are incorporated in the mathematical relationship known as Coulombâs law. The electric force on a charge Q1 under these conditions, due to a charge Q2 at a distance r, is given by Coulombâs law,The bold characters in the equation indicate the vector nature of the force, and the unit vector rÌ is a vector that has a size of one and that points from charge Q2 to charge Q1. The proportionality constant k equals 10â7c2, where c is the speed of light in a vacuum; k has the numerical value of 8.99 à 109 newtons-square metre per coulomb squared (Nm2/C2). Figure 1 shows the force on Q1 due to Q2. A numerical example will help to illustrate this force. Both Q1 and Q2 are chosen arbitrarily to be positive charges, each with a magnitude of 10â6 coulomb. The charge Q1 is located at coordinates x, y, z with values of 0.03, 0, 0, respectively, while Q2 has coordinates 0, 0.04, 0. All coordinates are given in metres. Thus, the distance between Q1 and Q2 is 0.05 metre.The magnitude of the force F on charge Q1 as calculated using equation (1) is 3.6 newtons; its direction is shown in Figure 1. The force on Q2 due to Q1 is âF, which also has a magnitude of 3.6 newtons; its direction, however, is opposite to that of F. The force F can be expressed in terms of its components along the x and y axes, since the force vector lies in the xy plane. This is done with elementary trigonometry from the geometry of Figure 1, and the results are shown in Figure 2. Thus,in newtons. Coulombâs law describes mathematically the properties of the electric force between charges at rest. If the charges have opposite signs, the force would be attractive; the attraction would be indicated in equation (1) by the negative coefficient of the unit vector rÌ. Thus, the electric force on Q1 would have a direction opposite to the unit vector rÌ and would point from Q1 to Q2. In Cartesian coordinates, this would result in a change of the signs of both the x and y components of the force in equation

Regards, The SS Ceylon was the first vessel repurposed to be a cruise ship. It was owned by the London-based ship brokerage Culliford & Clarke, which hoped to make cruising the centre of its business. The Ceylon was a single-screw, iron-hulled auxiliary steamerâmeaning that it had both a steam engine and sailsâand could hold up to 100 passengers. Its renovation had removed several dozen passenger cabins and replaced them with public spaces, including a dining room, a boudoir, a smoking room, and a steam-powered fairground organ. After its refit, the Ceylon offered the first around-the-world cruise in history. It departed from Liverpool in 1881 for its 10-month journey. However, it had difficulty attracting a full complement of guests, and the company failed to recover from the expense. In 1885 Culliford & Clarke went into liquidation. Nonetheless, the idea of cruising had begun to catch on. The charter for the Ceylon was soon sold to the British Regent Street Polytechnic school, which added more berths and began offering affordable and educational leisure cruises to its mainly working-class students. Other organizations and naval companies began to offer cruises, using older ocean liners or ships that were not needed for other business.The first cruise ship built solely for the purpose of leisure was produced by Albert Ballin of the German Hamburg-America Line company. Ballin spearheaded the development of the shipping companyâs cruise offerings, culminating in the construction of the cruise ship Prinzessin Victoria Luise. She was a 407-foot (124-metre), 4,419-ton vessel with twin-screw engines. Ballinâs target market was people who were rich but not rich enough to own their own leisure yachts. The ship thus had 120 exclusively first-class cabins. It also had a gymnasium, a library, an art gallery, a ballroom, and a darkroom. The Victoria Luise was launched on June 29, 1900, and operated until December 1906, when it wrecked near Jamaica. Though all passengers survived, the ship was unsalvageable. Popularity in leisure cruising declined after the grounding of the Victoria Luise, the 1912 sinking of the Titanic, and the outbreak of World War I (1914â18), which saw the sinking of the Lusitania in 1915.As countries began to recover from World War I, cruising slowly began to increase in popularity. In the United States, Prohibition (1920â33) drove the rise of affordable cruises. U.S. anti-alcohol law applied only as far as 3 nautical miles (5.6 km) from shore, and many shipping and ocean liner companies began to offer cruises outside this range. Some were simple âbooze cruises,â in which the ships traveled 3.1 nautical miles (5.7 km) out to sea and then essentially floated around for a few days. Others were trips to islands in the Atlantic Ocean and Caribbean Sea, catering to passengers interested in a holiday that would include alcohol. The Great Depression and the repeal of Prohibition gradually ended booze cruises, although some leisure cruises remained.The mid-century rise of cheap commercial flights across the Atlantic forced many naval companies to reorient toward cruising. Ocean liners, once essential to mass transportation, were largely repurposed as cruise ships. As older companies turned to cruising, many new companies exclusively focused on cruises were founded in the 1960s and â70s. These included Princess Cruises in 1965, Norwegian Cruise Line in 1966, Royal Caribbean Cruises in 1968, MSC in 1970, and Carnival Cruise Lines in 1972. These companies offered prices that were increasingly affordable for middle-class consumers, driving the industry to expand and more purpose-built cruise ships to be commissioned. The television show The Love Boat, which took place aboard a ship called the MS Pacific Princess, is generally credited for the explosion of the cruising industry in the 1980s. In 1987 Royal Caribbean launched the worldâs first megaship, MS Sovereign of the Seas. It could hold almost 3,000 passengers and became the model for all modern cruise ships as floating resorts. The Sovereign had five restaurants, nine bars, a spa, four pools, and a casino.
