Title          
Changes in Supply and Demand 
   
 
Abstract    

Practical uses of supply and demand analysis often center on the different variables that change equilibrium price and quantity, represented as shifts in the respective curves. Comparative statics of such a shift traces the effects from the initial eqilibrium to the new equilibrium.

People increasing the quantity demanded at a given price are referred to as an increase in demand. Increased demand can be represented on the graph as the curve being shifted outward. At each price point, a greater quantity is demanded, as from the initial curve D1 to the new curve D2. More people wanting coffee is an example. In the diagram, this raises the equilibrium price from P1 to the higher P2. This raises the equilibrium quantity from Q1 to the higher Q2. A movement along a given demand curve can be described as a "change in the quantity demanded" to distinguish it from a "change in demand," that is, a shift of the curve. In the example above, there has been an increase in demand which has caused an in increase in (equilibrium) quantity. The increase in demand could also come from changing tastes, incomes, product information, fashions, and so forth.

Title          
Supply 
   
 
Abstract    
In economics, supply and demand describe market relations between prospective sellers and buyers of a good. The supply and demand model determines price and quantity sold in the market. The model is fundamental in microeconomic analysis of buyers and sellers and of their interactions in a market. It is also used as a point of departure for other economic models and theories. The model predicts that in a competitive market, price will function to equalize the quantity demanded by consumers and the quantity supplied by producers, resulting in an economic equilibrium of price and quantity. The model incorporates other factors changing such equilibrium as reflected in a shift of demand or supply.

Strictly, very strictly considered, the model applies to a type of market called perfect competition in which no single buyer or seller has much effect on prices and prices are known. The quantity of a product supplied by the producer and the quantity demanded by the consumer are dependent on the market price of the product. The law of supply states that quantity supplied is related to price. It is often depicted as directly proportional to price: the higher the price of the product, the more the producer will supply, ceteris parib...

Title          
Applications of Supply and Demand 
   
 
Abstract    
The phrase "supply and demand" was first used by James Denham-Steuart in his Inquiry into the Principles of Political Economy, published in 1767. Adam Smith used the phrase in his 1776 book The Wealth of Nations, and David Ricardo titled one chapter of his 1817 work Principles of Political Economy and Taxation "On the Influence of Demand and Supply on Price".[10]

In The Wealth of Nations, Smith generally assumed that the supply price was fixed but that its "merit" (value) would decrease as its "scarcity" increased, in effect what was later called the law of demand. Ricardo, in Principles of Political Economy and Taxation, more rigorously laid down the idea of the assumptions that were used to build his ideas of supply and demand. Antoine Augustin Cournot first developed a mathematical model of supply and demand in his 1838 Researches on the Mathematical Principles of the Theory of Wealth.

During the late 19th century the marginalist school of thought emerged. This field mainly was started by Stanley Jevons, Carl Menger, and Léon Walras. The key idea was that the price was set by the most expensive price, that is, the price at the margin. This was a substantial change from Adam Smith's thoughts on dete...

Title          
Demand 
   
 
Abstract    
The laws of supply and demand state that the equilibrium market price and quantity of a commodity is at the intersection of consumer demand and producer supply. Here, quantity supplied equals quantity demanded (as in the enlargeable Figure), that is, equilibrium. Equilibrium implies that price and quantity will remain there if it begins there. If the price for a good is below equilibrium, consumers demand more of the good than producers are prepared to supply. This defines a shortage of the good. A shortage results in the price being bid up. Producers will increase the price until it reaches equilibrium. If the price for a good is above equilibrium, there is a surplus of the good. Producers are motivated to eliminate the surplus by lowering the price. The price falls until it reaches equilibrium. The demand schedule, depicted graphically as the demand curve, represents the amount of goods that buyers are willing and able to purchase at various prices, assuming all other non-price factors remain the same. The demand curve is almost always represented as downwards-sloping, meaning that as price decreases, consumers will buy more of the good.[1] Just as the supply curves reflect marginal cost curves, demand curves can be descri...

Elon Musk Gives a Tour of SpaceX 
   
 
Abstract    
SpaceX was founded in 2002 by former PayPal entrepreneur and Tesla Motors CEO Elon Musk with the goal of reducing space transportation costs to enable the colonization of Mars. It has developed the Falcon 1 and Falcon 9 launch vehicles, both of which were designed from conception to eventually become reusable, and the Dragon spacecraft which is flown into orbit by the Falcon 9 launch vehicle to supply the International Space Station with cargo. A manned version of Dragon is in development. [Source - Wikipedia]

Title          
Competitive Market Efficiency 
   
 
Abstract    

Perfect competition is an economic model that describes a hypothetical market form in which no producer or consumer has the market power to influence prices. According to the standard economical definition of efficiency (Pareto efficiency), perfect competition would lead to a completely efficient outcome. The analysis of perfectly competitive markets provides the foundation of the theory of supply and demand.

To be exhaustive, note that some economists[1] do not agree with this presentation of the model of perfect competition. Many reasons are advanced, but one of the main is that it focuses on unnecessary conditions (atomicity, perfect information...) while it does not allow an answer to the question : "If agents are price-takers, who sets the prices ?" Indeed, in this model, as firms and consumers can not set the prices, it can't be—as it is often said (e.g. below)—that it is the firms who fix them. So, actually, there is a need for a benevolent agent who proposes prices to firms and consumers and fixes the ones at which exchange will occur. They also think that the argument that a global entity called "the market" could fix the prices, when its constituents (producer...

Title          
Ruben's Tube 
   
 
Abstract    
The Rubens' tube, also known as the Standing wave flame tube, or simply flame tube, is a physics experiment demonstrating a standing wave. It shows the relationship between sound waves and air pressure.

A length of pipe is perforated along the top and sealed at both ends - one seal is attached to a small speaker or frequency generator, the other to a supply of a flammable gas(propane tank). The pipe is filled with the gas, and the gas leaking from the perforations is lit. When the speaker is turned on, the pressure changes caused by the sound waves will cause the flames to heighten in some areas and to lower in others.
If a constant frequency is used, it is possible to determine the wavelength by simply measuring with a ruler.

Title          
Jumping droplets help heat transfer 
   
 
Abstract    
Excerpt from MIT's Research Update - Many industrial plants depend on water vapor condensing on metal plates: In power plants, the resulting water is then returned to a boiler to be vaporized again; in desalination plants, it yields a supply of clean water. The efficiency of such plants depends crucially on how easily droplets of water can form on these metal plates, or condensers, and how easily they fall away, leaving room for more droplets to form. The key to improving the efficiency of such plants is to increase the condensers’ heat-transfer coefficient — a measure of how readily heat can be transferred away from those surfaces, explains Nenad Miljkovic, a doctoral student in mechanical engineering at MIT. As part of his thesis research, he and colleagues have done just that: designing, making and testing a coated surface with nanostructured patterns that greatly increase the heat-transfer coefficient.

The results of that work have been published in the journal Nano Letters, in a paper co-authored by Mil...

Title          
High voltage disconnect switch 
   
 
Abstract    

An electrical substation is a subsidiary station of an electricity generation, transmission and distribution system where voltage is transformed from high to low or the reverse using transformers. Electric power may flow through several substations between generating plant and consumer, and may be changed in voltage in several steps.

A substation that has a step-up transformer increases the voltage while decreasing the current, while a step-down

Title          
Stirling engine example 
   
 
Abstract    

This is intended as an example of how much power can be produced out of nothing but heat and air density, and how your car's engine has to overcome this.

Stirling's air engine (as it is referred to in early text books - see hot air engine history) was invented by Reverend Dr Robert Stirling and patented by him in 1816. When the name became simplified to Stirling engine is not known, but may be as recently as the mid twentieth century when the Philips company began to experiment with working fluids other than air - the instruction book for their MP1002CA (see below) still refers to it as an 'air engine'. The main subject of that original patent was a heat exchanger which Stirling called the "economiser" for its enhancement of fuel economy in a variety of applications. The patent also described in detail the employment of one form of the economiser in an air engine, in which application ...
