  1. Re:Wobble on Quake Changes Earth's Rotation, Moves Islands · · Score: 2, Informative

    The earth orbits the sun. Imagine there is an axis through the centre of the sun around which the earth is orbiting the sun.

    The earth also rotates. The axis of rotation of the earth does not point in the same direction as the axis of the orbit. This is why we say that the earth is tilted.

    The tilt keeps pointing in the same direction throughout the year, ignoring the fact that it wobbles.

    This means that in summer, the axis in your hemisphere will be pointing towards the sun. The sun will be high in the sky and the energy from the sun will fall directly onto the land so there is more energy per unit area and is hotter.

    In winter, the axis in your hemisphere will be pointing away from the sun. The sun will be low in the sky and the rays will strike the earth at an angle and so have less energy per unit area and is so colder.

    The seasons vary between these extremes.

    It also explains why Australia has summer when the UK has winter as they are on opposite sides of the globe.

    As an example of how the angle of the rays striking the earth varies the energy, shine a torch at a piece of paper from straight on. The torch gives out a particular amount of light and energy. Now tilt the paper - the circle of light will elongate into an oval of greater area than the original circle. The torch is still giving out the same amount of energy, it is just spread over a greater area. This means that each particle of the paper must be getting less energy.

    I hope that all makes sense!

    Now, on top of the tilt, there is a wobble. This is just a change to the tilt. If the tilt increases due to the wobble, the seasons will become more extreme (that is, the difference between summer and winter will increase). If the tilt decreases then the difference between winter and summer will also decrease. If there was no tilt, we would have no seasons.

    Have you tried LyX? It's essentially a GUI front end to TeX. You don't need to know TeX. It may not solve your issues with versatility (I still struggle with picture placement sometimes), but other than that it is very good.

    There is good documentation included as well.

  13. Re:Seamonkey over Firefox on Mozilla 1.8 Alpha 5 Out And About · · Score: 1

    Well I guess I was trolling a bit myself... :)

    I mostly prefer the way it works for what I do. I guess a large part of that is the fact that I'm so used to it that any change is a pain.

    I can't really tell much difference over startup times or responsivity (this is on Windows with the quick start enabled), I think the firefox interface is messier - too much candy. I prefer the way I have moz set up with text only buttons and as few of them as possible.

    The real gripe for me is the search bar. Why have a whole seperate bar? I realise that it can be removed and then you can use the url bar for searching, but this only appears to work if you type an invalid url or it cannot resolve a host to your search term. What if (for some bizarre reason), I wanted to search for "localhost"? In moz, you just type, press up and then enter. Easy.

    One last thing (that I can't comment on personally), but quite often there seem to be comments on slashdot discussing the problems with firefox. This is a skewed sample of course as I'm sure more people use firefox than mozilla so more are going to comment on firefox, but still. There is the infamous firefox/slashdot rendering bug (is that fixed yet?). It's never affected me. Likewise the story there was the other day on the stability of firefox. Obviously it's hard for me to say anything other than subjectively, but moz crashes infrequently enough that it is a big suprise for me if it does.

    Er, I think that's it :)

    I completely agree. I really don't get on with firefox. Besides, I use the browser, mail client and the calendar so getting the suite would make sense even if it wasn't better.

    Presuming you are using Mozilla (I don't use Firefox, but I guess it should work the same), find the file searchplugins/google.src in your mozilla directory.

    After the line starting

    You may also want to change the updateCheckDays value as well as it looks as though it will overwrite your modified google.src file (although I'm not sure about this).
