    Test Your Intuition of Physical Principles with OutPost Game

    Now that's determination! Good job! BTW, the links to the old Lunar Outpost all point to the newest version. BTWW... Does anyone have any ideas for some "nutty gizmos" that I could add to the ship that are physical in nature but fun to play around with?

    Test Your Intuition of Physical Principles with OutPost Game

    uh oh. There was a bug with outpost 14. Its Y-coordinate was out of Flash's reach, so I moved it up. I guess you're still going to the version with that bug in it?

    Test Your Intuition of Physical Principles with OutPost Game

    I wrote it in Flash MX. If you're interested in more flash goodies take a look at http://www.flahoo.com OK! I've fixed the high scores -- I think. The new game is at: http://www.martinelli.org/games/outpost/OutPost.html Check your "new" high score against the old one to make sure I...

    Test Your Intuition of Physical Principles with OutPost Game

    Good Job EL! Yep. That's what I've been doing to try to gauge the gas -- to see if there is enough to make it at all. Have you been able to make it from outpost 1 to outpost 11? If you can make it I'll leave the gas tank the same size. Thanks! Outpost 8 is right next to outpost 14...

    Test Your Intuition of Physical Principles with OutPost Game

    Who is EL? EL, whoever he is has beat my best score & I wrote the thing?! His best is 1730. I'm impressed! BTW, I've fixed the server side code so that hi-scores are sorted correctly, but I ran into a glitch with the Flash/client side. I'll keep you posted. And thanks for the...

    Test Your Intuition of Physical Principles with OutPost Game

    Well, it looks like I've got a couple of bugs left to fix. I kind of ignored the fact that multiple people could be updating the Hi-score file. (oops). I used Perl to do the server side stuff & didn't use sessions. I'll fix this it sometime this week. Yeah, its hard. But maybe its too...

    Test Your Intuition of Physical Principles with OutPost Game

    Here's a little game I wrote that uses a few basic physical principles. Test your intuition of momentum, (linear & angular), acceleration and force. http://www.martinelli.org/flash/OutPost.html Have fun!

    How do we know reason is right ?

    Logic that works is that which represents phenomena. statements that do not represent are not testable. E.g., "This statement is false." Doesn't represent any phenomena & is obviously untestable. It doesn't work. Although it appears to represent itself, "it" is purely abstract...

    The temperature of empty space What now?

    There are two things that come to mind when I consider that the acceleration might change the Standard Big Bang theory. First, it wasn't part of the SBB model, and it wasn't predicted. This seems pretty big to me. Second, the expansion is a big part of the dynamical properties (like...

    The temperature of empty space What now?

    Following Hubble's discovery of the expanding universe, George Gamow postulated that the universe began as a big bang & calculated the temperature of empty space to be around 3 degrees Kelvin. In the early 60's this temperature was confirmed. We now know that rate of expansion is...

    What is the smallest possible positive real number?

    Thanks Gerald! I was sure my fuzzy thinking was at least pointed in the right direction. I'll look into Nonstandard analysis somemore.

    Should Physics Forums Offer Premium Memberships?

    np. You might want to put together a list of ideas you've collected so far & post them on a heuristic poll & let people vote and/or add new ideas. After a couple of months you take a closer look at the top three ideas & choose.

    Big bang, schmig bang: everything's just shrinking

    Its not symetric. I don't know that the universe is actually symetric, but I think its a pretty good guess.

    Big bang, schmig bang: everything's just shrinking

    Nothing yet. Until someone derives the 26(http://math.ucr.edu/home/baez/constants.html) fundamental constants from a fundamental idea, I won't accept anything. The fundamentally correct idea, I think is: For every change there is an equal but opposite change.
