Social Network Marketing Basics

Saturday, September 5th, 2009

Establishing and maintaining an active presence on social networking websites has emerged as an effective way to promote products and drive traffic to websites. These and other Web 2.0 technologies are changing the way we approach internet marketing. In this article we look at how to make the most of social network marketing.

There are many terms for this form of web promotion, including social media optimization and social media marketing. And there are also different types of websites and methods that can be used.

As with any form of internet marketing, successful social network marketing takes patience, know how, and some hard work. Social network websites are essentially online communities where people can meet, communicate, and share ideas. How you should approach your marketing campaign on these websites will depend on the size and nature of your business.

Many large companies and corporations have already established a presence on these websites. However, for smaller companies and home-based web businesses a more subtle approach is probably the better option. Rather than blatantly marketing your product, you should try to become a member of the community by making friends and joining relevant groups on websites like Facebook and MySpace.

The Unruh effect

Sunday, August 9th, 2009

When studying for the uniform acceleration presentation, I was reminded of a wierd effect in the intersection between general relativity and quantum field theory, called the Unruh effect. It may blow your mind or simply make you shrug. I thought it prudent to present it anyhow, as it certainly blew my mind.

I did not put as much work into this as I would like. But the real justification for this effect is a bit beyond my scope, so you will have to make do with a popular science version akin to how the Hawking’s radiation (radiation from black holes) is presented in popular science.

Errata: I marveled that my simple popular science approach yielded the correct formula and not only a proportionality, but that was a bit premature. As you may recall, there was a ‘pi’ in my earlier expression of the temperature as a function of acceleration, which did not appear in the semi-classical dimensionality argument. So it wasn’t that big of a fluke, after all. Good thing, really.
