    Blogging Software?

    Thanks! Are you familiar with Drupal? I got round to trying it but it doesn't seem to be able to do what I want. I am trying to set up a site with three different blogs but I do not want to allow users to have their own blogs on the site. I am looking into tools like b2evolution and...

    Blogging Software?

    blogger ftp I found http://help.blogger.com/bin/answer.py?answer=121" [Broken] on Blogger. Does anyone use the ftp function on Blogger? Does it give you full control of the page on your site where it posts the blog or is it just like it would have been like posting in Blogger itself. The...

    Blogging Software?

    I am trying to set up a blog. I was just wondering if anyone had any experience of the different software available out there, like 'Simple PHP Blog', 'Blogsphere' etc. I want to be able to host the blog myself so I am not keen on Blogger and the other free hosted blogging tools out there...

    Using a mac

    Thanks for that loseyourname! Just wish this post was here about a month ago! I went through the same confusion about how OSX handles program installations. But I do like Adium! It lets me connect to all the different IM services in the one program and looks real sleek too!

    Using a mac

    I recently started using a mac too and yeah the latency of the track pad drove me nuts!! It took forever to move from one edge of the screen to the other. But I eventually found an add on that fixes that. http://homepage.mac.com/bhines/mousezoom.html" [Broken] Upon installation, it adds an...

    Help! File won't open:

    I don't think Win XP compression features can deal with .ace files. As far as I'm aware it can only handle .zip files. You need WinRAR for .ace files. You can get it as a trial version. http://www.rarlab.com/download.htm

    Parallel Worlds: A Question From Olbers' Paradox

    I don't get the speed limit thing either. I mean why would you say that the speed of space expanding outward is infinite relative to the nothingness? I mean if you take a piece of stretchy material and stretch it, the speed of the expansion of its edge relative to the outside world = the...

    Parallel Worlds: A Question From Olbers' Paradox

    Have you got any documentation on this?

    Parallel Worlds: A Question From Olbers' Paradox

    That was exactly my point. I have always heard claims that CBR observed nowdays dates from very shortly after the time of creation. But after some reading from here it seems that it actually dates from about a few hundred thousand years after the big bang. So it would then make sense that it...

    Parallel Worlds: A Question From Olbers' Paradox

    My question is centered on the fact that nothing can travel faster than the speed of light. At the time of the big bang, we were created as was everything else, including the cosmic background radiation. So bearing in mind that nothing can travel faster than the speed of light, how did we get...

    Parallel Worlds: A Question From Olbers' Paradox

    I understand that background radiation that we observe actually dates from the time of the creation of the universe (The Big Bang). I also understand that nothing can travel faster than the speed of light. My question is how did we (the solar system) get here before the radiation did...

    Computer Science Prospects in Canada Hi guys! I would like to know what you people think the prospects in Canada are in the field of Computer Science. I mean are there reasonable job prospects in that field in Canada? I have just graduated in Physics from the University of Birmingham in the...

    Changing Earth Orbit July 06! Is this for real?

    If we can alter the earth's orbit to be slightly further from the sun, it could solve climate issues such as global warming etc..

    Changing Earth Orbit July 06! Is this for real?

    Ha ha! I like it! Can't wait for the 20th July of next year to watch a bunch of blisfully ignorant fools jumping thinking it's gonna do something!! :rofl:

    Changing Earth Orbit July 06! Is this for real?

    Ok so basically if they gather enough people with no brains out there and they actually jump, it wouldn't help the earth's orbit at all but just result in some stupid earthquake! :surprised

    Changing Earth Orbit July 06! Is this for real?

    This site has a whole theory about changing the orbit of the earth by having 600 million people jumping at the same time. I am very skeptical about this. I mean it sounds like the violation of the conservation of energy/momentum if you can change the earth's orbit without any mass...

    What are Kernel Times?

    Thanks for the reply so-crates, I suppose that would indeed make sense: the portion of the processor used by the kernel. It doesn't seem like the kernel shows up as a process under the 'Processes' tab though, unless it's under some odd name.

    What are Kernel Times?

    I've recently noticed that there is a 'Show Kernel Times' option in Windows XP's Task Manager under the 'Performance' tab. This shows up as a red meter over the green 'CPU Usage' meter. I gathered that the Kernel is a piece of software that allows the operating system to multi-task but what...

    Snakes and Ladders

    Yes, writing a program is my plan. But I have been advised against doing it by literally taking an average with the computer playing the game many times. It is apparently very time consuming and yields very inaccurate answers. It can be worked out by probabilities from what I got told...

    Snakes and Ladders

    It's a board game that consists of an array of numbers from 1 to 100 that you play by rolling a die. You can find an online version here. You start the game off the board [if you get a 1 from your first throw, you move to square 1, if you get a 2, square 2, etc] and move according to the...

    Snakes and Ladders

    I want to calculate the average duration of a snakes and ladders game in terms of the number of moves. Does anybody have any idea on how to tackle the problem?

    Schools Best Physics Graduate Schools in Canada

    Do you know how much emphasis UBC lays on GRE subject test scores in regards to admissions? I really want to get into UBC but I took my Physics GRE on Saturday and I don't think I did so well. However, I have got very good references and I also have a publication in Condensed Matter Physics...

    Simple question on Conservation of Momentum and KE

    Thanks for explaining this. I always thought that the law of conservation of momentum was from the law of conservation of energy.

    I totally agree: Firefox rocks. Make sure you try out the extensions they have too.

    Simple question on Conservation of Momentum and KE

    I am having a bit of a conceptual problem with the conservation laws. Consider a system of two bodies of mass m each. One moving at speed V1 towards the second body which is at rest. For the case of an inelastic collision, I understand that the total kinetic energy of the system is not...

    Specular Reflection from a Reflection Diffraction Grating

    I understand that a laser beam shining onto a diffraction grating produces a 0th order, 1st order etc... diffracted beam. My question is: What is the wavelength of the specular reflection [0th order beam] off the grating in regards to the wavelength of the incident beam?

    Gain Curve for a Diode laser

    Ok, so would you say that the natural linewidth is the width of the mode that the laser is currently lasing at? Or is the natural linewidth [as the term 'natural' suggests] the linewidth associated with a single photon as emited from an atom?

    Gain Curve for a Diode laser

    Can someone please explain what exactly the gain curve of a laser is? Is it exactly the same thing as the natural linewidth of the laser [a graph of intensity vs frequency] or am I off track? I found this graphhttp://www.phys.ksu.edu/perg/vqm/laserweb/Ch-5/C5s1p5.htm [Broken] that tries to...

    What is meant by SINGLE LONGITUDINAL MODE in laser?

    Thanks Claude! I have a better idea of what mode hopping is now and I have come across some material that says the different modes that you can get for a laser diode are represented by a series of peaks under a so called 'gain profile' and that the wavelength at which the laser will operate...
