I work with all kinds of web related technologies, including my CMS of choice WordPress, I’ve even dabbled with Logo and stationary Designing, however I primarily work on Front-end Web Development projects.

I always make every effort to enforce web standards in my designs, and take extra care to ensure my sites are usable & functional from a user’s perspective.

Mercury is used for several reasons. Firstly it expands at a constant rate over the temperatures we are likely to encounter in everyday life (between -40 and 100 celcius, and even further in each direction). Secondly it does not freeze or boil between these temperatures, such as alcohol would do. The only drawback with mercury is that it is poisonous, but if you don't go round brealing thermometers in your mouth then you should be alright.
