Human perception of motion
1. A television system involves equipment located at the source of production, equipment located in the home of the viewer, and equipment used to convey the television signal from the producer to the viewer. The purpose of all of this equipment is to extend the human senses of vision and hearing beyond their natural limits of physical distance.
2. A television system must be designed, therefore, to embrace the essential capabilities of these senses, particularly the sense of vision. The aspects of vision that must be considered include the ability of the human eye to distinguish the brightness, colours, details, sizes, shapes, and positions of objects. Aspects of hearing include the ability of the ear to distinguish the pitch, loudness, and distribution of sounds.
3. In working to satisfy these capabilities, television systems must strike appropriate compromises between the quality of the desired image and the costs of reproducing it. They must also be designed to override, within reasonable limits, the effects of interference and to minimize visual and audial distortions in the transmission and reproduction processes.

How smartphones work
1. Thinking of a daily task it's likely there's a specialized, pocket-sized device designed to help you accomplish it. You can get a separate, tiny and powerful machine to make phone calls, keep your calendar and address book, entertain you, play your music, give directions, take pictures, check your e-mail, and do countless other things. But how many pockets do you have? Handheld devices become as clunky as a room-sized supercomputer when you have to carry four of them around with you every day.
2. A smartphone is one device that can take care of all of your handheld computing and communication needs in a single, small package. It's not so much a distinct class of products as it is a different set of standards for cell phones to live up to.
3. Unlike many traditional cell phones, smartphones allow individual users to install, configure and run applications of their choosing. A smartphone offers the ability to conform the device to your particular way of doing things. Most standard cell-phone software offers only limited choices for re-configuration, forcing you to adapt to the way it's set up.

Hyperinflation
1. Inflation is a sustained increase in the aggregate price level. Economists generally reserve the term hyperinflation to describe episodes where the monthly inflation rate is greater than 50 per cent.
2. Hyperinflations are largely a twentieth-century phenomenon. The most widely studied hyperinflation occurred in Germany after World War I. The ratio of the German price index in November 1923 to the price index in August 1922 – just fifteen months earlier – was 1.02 × 1010. This huge number amounts to a monthly inflation rate of 322 per cent.
3. Hyperinflations are caused by extremely rapid growth in the supply of «paper» money. They occur when the monetary and fiscal authorities of a nation regularly issue large quantities of money to pay for a large stream of government expenditures. In effect, inflation is a form of taxation where the government gains at the expense of those who hold money whose value is declining. Hyperinflations are, therefore, very large taxation schemes.

Insurance
1. Insurance plays a central role in the functioning of modern economies. Life insurance offers protection against the economic impact of an untimely death; health insurance covers the sometimes extraordinary costs of medical care; and bank deposits are insured by the federal government. In each case a small premium is paid by the insured to receive benefits should an unlikely but high-cost event occur.
2. An understanding of insurance must begin with the concept of risk, or the variation in possible outcomes of a situation. A shipment of goods to Europe might arrive safely or might be lost in transit. A person may incur zero medical expenses in a good year, but if he is struck by a car, they could be upward of $100,000.
3. We cannot eliminate risk from life, even at extraordinary expense. Paying extra for double-hulled tankers still leaves oil spills possible. The only way to eliminate auto-related injuries is to eliminate automobiles. Thus, the effective response to risk combines two elements: efforts or expenditures to lessen the risk, and the purchase of insurance against the risk that remains.

World Bank
1. World Bank or International Bank for Reconstruction and Development is a multinational institution set up in 1947 to provide economic aid to member countries - mainly developing countries – to strengthen their economics. The Bank has supported a wide range of long-term investments including infrastructure projects such as roads, telecommunications and electricity supply; agriculture and industrial projects including the establishment of new industries, as well as social, training and educational programmes.
2. The Bank's funds come largely from the developed countries, but it also raises money on international capital markets. The Bank operates according to 'business principles' lending at commercial rates of interest only to those governments it feels are capable of servicing and repaying their debts.
3. In 1960, however, it established an affiliate agency, the International Development Association, to provide low-interest loans to its poorer members. Another affiliate of the World Bank is the International Finance Corporation which can invest directly in companies by acquiring shares.
