categories (which is the majority of them, at least in our own galaxy) is as follows: First deduce the likely temperature and size of the star from its dominant colour and the atomic spectra present in its light (temperature is related to colour, and different chemical elements are produced under different conditions of temperature and pressure, which in turn depend on the mass and age of a star). From these we can work out the likely luminosity. From the luminosity we can deduce the stars absolute magnitude [1] (i.e. how bright it would appear at a standard, fixed distance of 10 parsecs from us). Comparing this with the star’s apparent (i.e observed) magnitude, we can then calculate it’s actual distance from us. To me, this method of deducing a star’s distance from us merely by studying its light, and then doing a few calculations based on thermodynamics, nuclear physics, atomic physics and stellar dynamics, represents one of the most beautiful examples of the power of human ingenuity and careful, deductive reasoning in the history of science.

So, I’ve been working at this company for nearly a Travel Gift, Summer Shirt, Vacation Shirt, from January. I needed a job as was being made redundant and this popped up so I took it, it’s a night shift but work is work. Now, after about three months, I was asked by my colleague if I could cover his shift as he had an evening event to go to which I said that’s fine I came to find out it was a company event where everyone is invited to it but me. I shrugged it off as I thought I’m new so I guess they had it booked for a while. Kinda still sucked having to cover someone’s shift though as they were having fun and I’m stuck in the office. Anyways, fast forward to about a month ago I was doing paperwork and I came across an email stating Christmas party, I brought it up with my colleague he said is there? To which I said yeah at this place he said oh yeah I know I’m going to that. I was struck as I had not been approached or invited to it, what makes it worse is as there has been a boom in work lately they have took on about 6 new people about 3 months ago and they have all been added to the guess list and they class each other now as “family” while I’m stuck covering the guys shift and I was told I need to have the on call phone over Christmas because he has a family?! Well so do I!!!
