    Other Becoming an Engineer: Considerations and Personal Experiences

    WA mechatronic? I'll look over the rest of the thread when I have a bit more time than I currently do, but in the meantime: I'm currently enrolled in my first year of a bachelor of engineering at Curtin University in Perth, Western Australia and currently have told most people I'm thinking of...

    My Taylor Square Root C Program doesn't like me

    So the problem was a conceptual one then? That's a shame. Yeah, I figured that imprecision with floats would come into effect with a series, but I was hoping that (-1)^n might bounce the number around a bit til it was close enough to the right value. But statistics doesn't really let that...

    My Taylor Square Root C Program doesn't like me

    Aaw really? Is that just a thing with square root or is it just my method isn't that great?

    My Taylor Square Root C Program doesn't like me

    Homework Statement 4. Implement a simple method to find the square root of a double precision floating point number x. A simple method is to consider the error produced by a “guess” y of the solution. Square the value y and compare with the value x. If y is correct, the error e=|y2-x| where ||...

    Hubble's law and the age of the universe

    Thanks for the replies. So Hubble's constant is far from constant? That makes sense, cool. I was thinking a bit after making that little equation and thinking that it didn't seem to work because other objects further away would indicate on older universe than closer ones and very low...

    Hubble's law and the age of the universe

    Hubble's law states that the speed of a distant object is proportional to it's distance (this implies an expanding universe). By finding the distance and speed (via redshift) of various distant galaxies you can produce a graph displaying the linear relationship. The gradient of the line is...

    Hubble's law and the age of the universe

    Dratting edit expiration, sorry about the triple post. I'm moving this to differential equations.

    Hubble's law and the age of the universe

    Oops: v2r = GM2 r = GM2/v2 r = 6.67 × 10-11 × M2 / 642 = 1.6 × 10-14 × M2 Hence multiply by 3.3 × 10-14 This mistake is restricted to the calculation on this forum.

    Hubble's law and the age of the universe

    Just did a test today (so no results back yet) (year 12 physics) and it annoyed the heck out of me, in part because to answer these questions you had to make preposterous assumptions, assumptions which in hindsight I probably should have just stated as opposed to writing out explanations as to...

    What is the Twin Paradox and how does it illustrate time dilation?

    Okay thanks guys, that works. I'm not sure about this bit. Just to bring in another illustration to confuse things, when they put that atomic clocks on the plane and left the other where it was, which one was behind? Because they were both traveling fast in relation to each other.

    What is the Twin Paradox and how does it illustrate time dilation?

    Thanks for the insanely fast replies. @DaleSpam, okay, I think that makes sense. So that means a fast moving body will measure distances differently to one static in relation to what they're measuring. Oh yeah of course, I remember that bit now. To someone else it would appear the ship is...

    What is the Twin Paradox and how does it illustrate time dilation?

    Well, not in the story, I made that up. I got that situation by regurgitating what I've heard before(eg. ww(totallynotalinkmodguy)w.youtube.com/watch?v=sYOO2mOjo9s&t=14m57s), that if you travel towards someone, than relativity apparently says that time appears slower for you to someone else...

    What is the Twin Paradox and how does it illustrate time dilation?

    Okay maybe it's not just the Ender's Game series, and maybe its actually a cornerstone fact belief theorem postulation thing of relativity, but still! In the story Ender travels in ships which go at relativistic speeds. By doing so, centuries go past but he hardly ages at all. I don't get this...
