Electrons and the Quantum World


Our conception of the atom has undergone many changes since the day the idea that matter consisted of indivisible particles was first floated by the Indians and Greeks. However it is only in this century that we have come to know something of what truly goes on inside the atom. We are all by now familiar with the iconic picture of an atom – a circle with a couple of little circles whizzing around it, rather like the moon orbits the earth. In the case of the atom, the ‘earth’ is called the nucleus and the ‘moons’ are called electrons.

What keeps the electrons hanging around the nucleus? Well, if you remember the old adage ‘like charges repel, unlike attract’: electrons have a negative charge, and the nucleus has a positive charge. The flipside of this is that the electrons need energy if they are to avoid spiralling into the nucleus. This was one of the main questions at the beginning of the century: where does this energy come from? The answer turns out to be

How You Can Sell Electronics


Are you in need of some extra money? You’ve probably got a ready source of cash in your home, and don’t even realize it. It’s true. Thousands of people accidentally get rid of or throw away things that they could be using to earn some extra income- their used and unwanted “electronics Recycling”. If you have any old cell phones, BlackBerrys, laptops, or other electronics in your home, you have a way to make yourself some money. It’s surprisingly easy to sell electronics, and it can help you get some quick cash.

Not everyone thinks that selling their used electronics is for them. Most people don’t bother to sell electronics for one of three reasons:

– Their electronics are broken, and they don’t think anyone will want them.
– They think trying to sell electronics would be too much work.
– They don’t think they’ll get enough money to make selling their devices worthwhile.

The thing about broken electronics is that, no matter how broken they are, they

What’s In The Future For Electronics


Electronics recycling in the U.S. is growing as the industry consolidates and matures. The future of electronics recycling – at least in the U.S., and perhaps globally – will be driven by electronics technology, precious metals, and industry structure, in particular. Although there are other things that can influence the industry – such as consumer electronics collections, legislation and regulations and export issues – I believe that these 3 factors will have a more profound impact on the future of electronics recycling and electronics component.

The most recent data on the industry – from a survey conducted by the International Data Corporation (IDC) and sponsored by the Institute of Scrap Recycling Industries (ISRI) – found that the industry (in 2010) handled approximately 3.5 million tons of electronics with revenues of $5 billion and directly employed 30,000 people – and that it has been growing at about 20% annually for the past decade. But will this growth continue?

Electronic Medical Record

An Electronic Medical Record is a secured electronic file of patient history, medical transcription notes, billing information, and all other information necessary to have a complete patient profile. It is true that the electronic medical record is indicative of a faster-paced informational age in which larger quantities of information require more effective database infrastructure, but there are many more benefits to both the medical service provider and the consumer. This informational article points out 10 benefits of an electronic medical record of which both practices and patients need to be aware.

1. Speed

As mentioned in the introduction, the business world of the 21st century is fast-paced. Even in medical practices, speed equals ability to compete, especially when managing information. That is why an electronic medical record system, or EMR, is used by most medical practices. In addition, a fast electronic medical record system requires less time invested in trouble shooting and allows more time invested in caring for patients.

2. Storage

An electronic medical record is an electronic database of information capable of carrying much more information

Electronic Component Suppliers

You will find many suppliers of electronic components who will sell them in small quantities. Suppliers of new components, or in a few cases “new and some used” components, include Digi-Key (having blue LEDs, prices reasonable), Mouser Electronics (Fast service, $20 minimum, $5 charge under $20, export orders $100 minimum), Ocean State Electronics (good collection of RF parts, especially air variables and B&W coils), Radiokit (lots of components), Circuit Specialists Inc ( no minimum with check or money order, or else $15, good RF collection), Active Electronics (many stores across the US and Canada, $25 minimum), Maplin Electronics Ltd. (UK), Newark Electronics ($25 minimum, prices on the higher side but have a lot of things that are hard to find elsewhere), Arrow Electronics, Inc. (minimum $25, accepts personal order also), MCM Electronics (minimum $20, mostly VCR parts and lots of useful stuff difficult to find elsewhere), and Fordham Radio Supply (tools for technicians).

Other companies include Jameco (computer parts and electronic components), JDR Microdevices (now no minimum order), Johnson Shop Products (new and some used electronic components), DC Electronics (good collection of ICs and electronic components), International Components Corporation (capacitors, diodes, ICs, potentiometers,

Electronic Check Conversion

What Kinds of Electronic Check Conversion Exist?

There are two major types of electronic check conversion – electronic check conversion and electronic check conversion with check guarantee. Before jumping into the key difference though, it’s helpful to spend some time explaining electronic check conversion in general.

Electronic Check Conversion Explained Using Credit Cards

The best way to explain electronic check conversion (and even electronic check conversion with check guarantee) is to point to credit cards. Years ago, instead of swiping credit cards into an electronic reader, merchants had to physically place them into a metal contraption, along with a two-piece carbon form. A heavy roller created an imprint of the credit card. After signing the form, one copy stayed with the store and the other went to the purchaser.

But in the last twenty years shoppers and stores forego using extra paper since everything is stored electronically thanks to the electronic reader. With electronic check conversion an amount is entered and the check is scanned, much like credit cards today. When the transaction is complete the check is given back to the customer since

Electronic Equipment Repair

Electronic equipment repair? Yes it is true if you wanted to. Everyone has their passion since when they are young and some begin to know it at the later age. There are many kinds of interest and passions such as wanted to be a singer, dancer, artist, lawyer, doctor, police, scientist and so forth. But in this article, I’m talking about the passion of the electronics. Once you are certain that electronics is the field that you are going to venture in, then do your best to acquire the necessary knowledge about electronics-look beyond the dollar signs. Find a job you are passionate about and you will increase your chances of having a long and successful career.

Do not give in to pressure from parents or other forces or base your decision on the money will make. You may get a good paying job but you may not necessarily be happy. If your work does not match your values, interests and personality, it will not be long before you feel the strain. You need the passion in you to keep yourself going on bad days.

Sometimes being passionate about your

Tips On Consumer Electronics

Never has there been a time like the present, where the consumer electronics department is filled with rivalry and advancement. The evolution of consumer electronics, high definition displays, digital broadcasts, displays and media is happening at an increasingly rapid pace.

From analog to digital, consumer electronics are now evolving with (Wireless Fidelity) technology. Are you concerned about having the latest technology when you make your next purchase in consumer electronics? Fundamentally, the changes in the consumer electronics industry are not being driven by product evolution, but by fluctuations in the industries business models.

One of the biggest contributions to consumer electronics, from the Internet is that it has paved the way for the development of more convenient ways to communicate such as through e-mail, chat and video conferencing. Now for the fun part the consumer electronics that entertain us! Where to start? One of the most popular items found at a discount consumer electronics store these days is the LCD television.

As a result, the prices that you can expect to pay for electronics would be lower than what you would expect to pay if you went

Seeking a Career in Electronics

People who like tinkering with malfunctioning electronic gadgets or have a knack for fixing broken televisions can become great employees within the electronics career field. Today, there are plenty of job opportunities and career choices within the electronics industry that allow individuals to explore technical aspects, creativity, and sales. With appropriate education and experience, one can make a decent living in the electronics field by pursuing a variety of exciting and challenging career opportunities.

Common Electronics Careers and Jobs

Electronics engineers are responsible for an array of technologies that span portable music players to global positioning systems (GPS). Many electronics engineers also work closely with computers and other electronic equipment. A variety of skills are associated with this type of job position, which deals with communications, control systems, and signal processing. Usually, a specialty is attached to the title of electronics engineer. An example of this is seen in the aviation electronics engineer that works for the military. There are also analysts in this field, such as the Airborne Electronics Analyst in charge of controlling airborne electronic systems that identify ships and submarines. They also help with vital search and

The Most Effective Advertising Medium

A decade ago most of us sat in awe when viewing a huge full color full motion video screen at a professional sports stadium, or at a concert by one of many famous international musical groups. That cutting edge technology is available today at a fraction of the cost of products manufactured ten years ago, and the visual experience is far superior! If your company has an annual advertising budget of $50,000 or more, the question is no longer “can we afford an electronic message center”, it has become “can we afford NOT to invest in an EMC?”.

Consider the following facts from the Small Business Administration:

1) According to the Small Business Administration, sales increase between 15 and 150% when and electronic message center is installed.

2) Electronic message centers allow an unlimited number of message changes and variable controls, all easily completed with a computer. The result is lower labor cost and elimination of the physical liabilities often associated with copy changes on traditional reader boards.

3) Electronic Message centers communicate variable messages as people pass by, allowing greater flexibility in communicating

Electronics Recycling

How does electronics recycling help? One cell phone can contaminate one hundred fifty-eight gallons of water? Two and a half ounces of oil are used to make one ink-jet cartridge, and in 2004 the number of ink-jet cartridges thrown away, if stacked end-to-end, would circle the earth? In short, electronics recycling helps not only you, but everyone around you. It’s one of those things where what you do personally actually helps others.

Electronics recycling has been ramped up via rapid technology change, low initial cost, and planned obsolescence. This makes for a fast-growing surplus of electronic waste around the world. Electronic waste is a “rapidly expanding” problem. Technical solutions are available, but in most cases a bundle of prerequisites such as legal framework, a collection system, logistics, and other services need to be implemented before application of that technical solution. Whether its been applied or not, electronics recycling, in the present, helps.

In America, an estimated seventy percent of heavy metals in landfills comes from discarded electronics, while electronic waste represents only two percent of America’s trash in landfills. The EPA says that unwanted electronics totaled two million tons in

How to Find Responsible Electronics Recycling Companies

Not long ago, CBS’ “60 Minutes” program broadcast a story on e-waste and global dumping. The reporters followed a trail of electronic recycling items from a Denver-based company all the way to Hong Kong, China and caught the so-called “recycling” company red-handed engaging in global e-waste dumping.

With over 80% of recycled electronics and computers ending up as high-tech e-waste in developing countries such as China, India, and Africa, we need to step up as responsible citizens of the world and choose computer and electronics recycling companies very carefully. We must support only those electronics recycling companies that are running both a socially and an environmentally sound operation, end-to-end. To understand how global dumping occurs, it helps to first understand the business model for electronic recycling.

To sustain as a business, electronic recyclers must generate enough revenues from all its recycling and reuse services and the reclamation of precious metals and other recycling materials, minus operating costs and the cost of de-manufacturing those items that yield no value (yet harm the environment).

The difference between an environmentally responsible computer and electronics recycling company and an irresponsible one can be broken down as follows: a) the

You Can Sell Broken Electronics

Have you ever had a cellphone that you dropped in a puddle? Or a laptop with a cracked screen? Sometimes, replacing the broken parts of your electronics is almost more expensive than just replacing the devices themselves. That’s assuming you even know how to fix whatever parts need fixing to begin with! Unfortunately, if you don’t, you just end up with a pile of useless, broken things. The goods news is that you can turn that pile of useless, broken electronics into a pile of money, if you know where to sell broken electronics.

For a long time, broken electronics only had two eventual homes- a landfill or a recycling plant. A landfill is a terrible place for electronic devices, since they contain components that can pollute when they’re damaged. So, you might throw away a water-damaged cell phone, but if its screen is cracked in the process, it’ll end up releasing mercury. A recycling plant is better, but still not the best choice. It takes a lot of energy to break down electronics for recycling, and burning off the waste products that can’t be recycled creates pollution. In the end, unless your

State Of The World To The Lonely Electron

With respect to a Lone Electron universe, let’s consider…

ACCELERATION/DECELERATION: None. The same argument applies as with velocity.

ARROW OF TIME: If there is no time experienced by the Lone Electron, then there can be no arrow of time either. In short, the Lone Electron has no experience of a past, present, or future.

CHARGE: Yes, the electron has a charge of minus one or in other words a negative charge of one unit. However, in order for charge to be meaningful, it has to be acting with or against another charge of which there is none. So, does our Lone Electron have charge in this context or doesn’t it?

COLOUR: An electron is colourless. In any event you need photons, electromagnetic energy, light waves, to transmit (wavelength and frequency) what we (our brains) interpret as colour. Our drab, bland, colourless Lone Electron has no photons to transmit any information about itself, and there are no eyeballs and brains to interpret that information in any event.

ELECTROMAGNETISM: The electron is most associated with electromagnetism and the electromagnetic force. The associated force

Precautions to Take While Handling Electronic

Electronic items are loved by all. However, do you know about the precautions that you need to take while using electronics? Well, not many do know a lot about the precautions that need to be taken. Electronic items can be delicate and it is necessary that the proper precautions are taken to protect the device.

Understanding the basics

Electronics and electrical equipments are a very important and inevitable part of day to day lives. However, one needs to know how to handle and use these electronic items as well.

Precautions while handling electronics

All the electrical appliances and electronics are semiconducting devices and have circuit designs. So it is very important to handle them properly so as to minimize damage and malfunction. Circuits can malfunction under different circumstances. One of the most common causes of damage to these electronics is the application of stress like variation is temperature, the rate of current flow and the voltage applied. These variables should always be kept within the limits which are permissible by the manufacturer.

Electronic Signatures-Esign Origins, Understanding Laws

On June 30, 2000 President Clinton signed the “Electronic Signatures in Global and National Commerce Act” (ESIGN) using his electronic signature ID, and thereby established the validity of electronic signatures for interstate and international commerce.

In the fours year prior to this Act’s passage a dozen states had passed similar laws and guidance for state specific business purposes, and in the five years since the Act’s passing every other state has passed similar laws and legislation. What does it all mean, and in the end how can it benefit businesses, individuals and the nation or world as a whole?

The best way to answer a question like this is to take a look at the origins of the law, and understand the reasoning behind its passage and the passage of the state specific laws.

The Birth of the Electronic Signature – Faxing

In the 1980’s companies and even some progressive individuals began using fax machines for high priority or time sensitive delivery of paper based documents. Today, the fax machine is a staple of the business world. Most people do not even consider the

Study on Electronic Money

Commerce refers to all the activities surrounding the purchase or sale of goods or services. As we step into the next century, the Internet promises to bring unpredictable change in the society. Spanning the entire globe, crossing all boundaries, the net has redefined the methods of communication work, study, education, interaction, Entertainment, Health, Trade and commerce. There are some activities in commerce such as marketing, sales, payment, fulfillment, customer service etc.

Electronic commerce is the application of communication and information sharing technologies among trading partners to the aim of business objectives. Electronic Commerce is associated with the buying and selling of information, products and services via computer networks.

Electronic Commerce is a new way of conducting managing and executing business transactions using computer and telecommunication networks. Electronic Commerce refers to the paperless exchange of business information using EDI (Electronic Data Interchange), Electronic Mail, EFT (Electronic Funds Transfer) and other networks based technologies. Electronic Commerce applications started in the early 1970s, with such innovations as EFT.

Why Are All Electrons Identical?

Go to your local store and buy several items of the same product – say a package of three golf balls. Though the golf balls appear identical, closer examination will reveal ever so slight differences. One ball maybe fractionally larger; another ever so slightly less spherical; perhaps the third is ever so slightly lighter. The generality that extends from this is that any two seemingly identical products will have nevertheless slight variations in their properties.

Now buy a packet of three electrons (or their antimatter equivalent, the positron). Each electron, or positron, will be identical in size, mass and electric charge to as many decimal places as you care to measure. All electrons (and positrons) are 100% absolutely identical clones.

Take one electron and one positron and bring them together. They annihilate releasing a fixed amount of energy. Take another electron and another positron and repeat the scenario. The pair will annihilate releasing an identical amount of energy in the process. The amount of energy released in each electron-positron annihilation case is the same, to as many decimal places as you can measure. That’s quite unlike taking a match from

(E-Invoices) For The Spanish

– What is an electronic invoice?

– What are the benefits of implementing electronic invoices?

– What are the principal laws governing the use of electronic invoices in Spain?

– Which types of electronic invoices are recognized in Spain?

– How can I convert paper invoices into electronic invoices and vice versa?

First of all, we want to point out that there are many synonyms for digital billing: digital invoicing, electronic billing, electronic invoicing, e-billing, e-invoicing, telematic billing, telematic invoicing, etc.

What is an Electronic Invoices or e-Invoices

An electronic invoice (also called an e-invoice or eBill) is the result of a billing method that doesn’t require a paper copy as a backup in order to demonstrate its authenticity. For this reason, an electronic invoice functions as a software-generated file, which compiles the information related to a commercial transaction, its payment and corresponding tax obligations.

Although we know perfectly well what an invoice is, its technical definition is “a document that reflects the delivery of a product or the provision of services,

Electronic Music History and Today’s Best Modern

Electronic music history pre-dates the rock and roll era by decades. Most of us were not even on this planet when it began its often obscure, under-appreciated and misunderstood development. Today, this ‘other worldly’ body of sound which began close to a century ago, may no longer appear strange and unique as new generations have accepted much of it as mainstream, but it’s had a bumpy road and, in finding mass audience acceptance, a slow one.

Many musicians – the modern proponents of electronic music – developed a passion for analogue synthesizers in the late 1970’s and early 1980’s with signature songs like Gary Numan’s breakthrough, ‘Are Friends Electric?’. It was in this era that these devices became smaller, more accessible, more user friendly and more affordable for many of us. In this article I will attempt to trace this history in easily digestible chapters and offer examples of today’s best modern proponents.

To my mind, this was the beginning of a new epoch. To create electronic music, it was no longer necessary to have access to a roomful of technology in a studio or live. Hitherto, this was solely
