I always wondered…
…how surround sound works…

Home theater surround sound has two main components. First is the A/V receiver, which receives, decodes and sends both audio and video signals. Second are the speakers. The speakers are divided onto channels: Left, center, right, surround and subwoofer. The notation of the surround sound is as follows: [Number of surround speakers].[number of subwoofers] (i.e. 5.1 = five surround speakers and one subwoofer).

Surround sound comes to us in two forms: analog and digital. Analog surround is contained in two channels. The left and right channels contain two out of phase signals each. In the left channel, the left front speaker gets one signal and the left rear speaker gets the other, out of phase signal. The same occurs in the right channel. A center channel is constructed out of the two front speaker signals. Unlike analog, digital surround sound is recorded as ones and zeros. As such, it is the only format that can be recorded onto DVD’s. Each channel is a separate track of the recording medium.

The center channel acts as the anchor of the system; producing the majority of dialog and effects. The left and right speakers remove the majority of the dialog. Rear surround speakers create sound effects, which help to create the illusion of being in the action. The Low Frequency Effects (LFE) channel sends bass to the subwoofer.

The most common surround sound formats are Dolby Pro Logic (logo pictured) and Digital Theater Systems (DTS, logo pictured).

I always wondered…
…how a laser works…

Laser is an acronym for “light amplification by stimulated emission of radiation”. A basic laser (pictured) is made up of a flash lamp (similar to a camera flash), a rod of the material to be lased (solid, liquid or gas) and two mirrors (one of which is only partially reflective).

Lasers use intense light flashes to “pump” up atoms of a solid or gas so that the atoms release photons. The photons are released in all directions, but only the photons traveling perpendicular to the mirrors will become the laser beam. As photons pass other atoms, more photons are spontaneously created from the other atoms. These photons will travel in the same direction and have the same phase and wavelength as the original photon.

Some of the photons pass through the partially reflective mirror as a concentrated beam of light. The laser light can have many uses from simply acting as a pointer to reading the information on a CD or DVD to cutting through hard materials. The strength of a laser is determined by the wavelength of the emitted light.

Lasers are classified into four broad areas based on the potential for biological damage (Laser warning symbol pictured). Class I lasers do no biological harm, though Class IA lasers are “not intended for viewing”. Class II lasers rely on the human aversion to light to protect eyes. Class IIIA lasers are harmful to human eyes if the beam is projected directly into the eye. Most laser pointers are Class IIIA. Class IIIB lasers are moderately-powered. Class IV lasers are the most powerful lasers and are a fire hazard and skin hazard. Class IV lasers have very strict regulations for usage.

…how a touchscreen works…

There are three basic types of touchscreen technologies: resistive, capacitive and surface wave acoustic.

Resistive touchscreens employ two thin metallic layers, one resistive and one conductive. When pressure is applied on the surface, one layer touches the other. The change on electrical field is noted and plotted.

Capacitive touchscreens use a layer that stores electrical charges on top of the glass panel of the monitor. When a user touches the screen, some of the charge is transferred to the person. Circuits located in each corner calculate the change in current. The relative differences in current help the computer to plot the point of contact.

Surface wave acoustic touchscreens have two transistors on the surface of the monitor which create ultrasonic waves on top of the screen. Opposite of the transistors are reflectors which bounce the waves back. When a wave is disturbed, the computer is able to plot where the touch occurred.

Resistive and surface wave acoustic screens do not distinguish between stimuli, because they recognize touches by pressure or disturbance. Capacitive does require a conductive input such as a finger to disturb the electrical charge on the surface.

…how a fax machine works…

A fax machine is basically a scanner, a printer, a modem and a phone put together. When a document is placed into a fax machine, the scanner looks at the page one line at a time. It translates that line into 1728 separate bits of information. The bits of information either represent a black dot or a white dot. There are 1145 lines on a page in the standard setting of a fax machine (there are higher settings for finer resolutions). Therefore there are approximately 2,000,000 bits of information on a page. If there are large areas of black or white, the data can be compressed to relay that info, thus saving lots of time in faxing. The information is then sent via phone line to the receiving fax machine. That device then decodes, decompresses and reassembles the bits to duplicate the original document.

I always wondered…
…how a stock exchange works…

Businesses listed on a stock exchange are equally divided into shares, which are publicly bought and sold. For example, a business worth #1 million might be divided into 10,000 shares worth $100 each. Each share represents a claim in the company. Whoever holds the majority of the stock has control of the company. Some companies pay money to each shareholder based on profits for a year. These payments are called dividends.

Stocks are traded at a stock market, or stock exchange, to centralize all trading so that buyers and sellers can go to one place. Rather than traveling all the way to the actual stock market, potential buyers and sellers contact stock brokers to do their business. When businesses publicize positive or negative news, the stock prices will fluctuate based on that news. Good news = more buying = higher prices. Bad news = more selling = lower prices.

There are two different ways a company can approach the stock market. They can either sell as an income stock or a growth stock. Income stocks pay dividends to shareholders. Growth stocks invest the money from share sales back into the company so that share prices continue to go up.

The New York Stock Exchange (NYSE, Wall Street front pictured) is the largest such market in the world. As of December 31, 2006, the NYSE had a total capitalization of $25 trillion.
