  1. The system would have to detect thinks like a little kid running into the highway to fetch his ball, or a deer. It would have to detect them before they were on the highway, as they could run in front of the car and there would be little time to dodge. I'd agree that we can take care of navigation via GPS by now. Construction zones might be another problem.

     

    What if you prevent them from running onto the highway in the first place? I'm thinking a security fence alongside or something.

     

    Or maybe we just trust that people won't run across highways. Sort of how we deal with railroad tracks, and, well, highways.

     

    For construction zones, perhaps an automated detour?

  2. The goal is to find some R such that g® is 9.80665 m/s2.

     

    I can't find a closed form solution; that doesn't mean that one doesn't exist.

     

    :mad: Damn. And it sounded like such a fun problem.

  3. And be specific about how this cap bank will be applied, as it really helps the design. Like if they are all in parallel, you can just use a regulated supply with a resistor on the output. If it is for a marx generator, or voltage doubler, you will have to use something else.

  4. You can only get away with not putting a number, when there is only one place the group could go. Ex: methylpropane. 1 and 3 methylpropanes don't make sense, as they would be n-butane. Therefore, the only methylpropane is 2-methylpropane.

  5. Density becomes a function in terms of pressure.

     

    Pressure is a function in terms of force from overlying mass and radius.

     

    Radius is a function of total mass and density.

     

    Force from overlying mass is a function of underlying mass, radius, and overlying mass.

     

    I ended up running in circles, since they are all functions of each other. I think I need an assumption, which will simplify one of the variables. I'm not sure what exactly I can assume though.

  6. I also don't follow your reasoning regarding predestination

     

    I think his original premise was that everything came from the big bang. Therefore, the current state of the universe is entirely described by the position and momentum (I think, correct me if I am wrong) of every particle present in the big bang.

     

    IMO this doesn't take into account random events that are quantum in nature. So the original premise is still false.

  7. Interestingly, Obama has SO much money that he's actually purchased half hour tv spots in which he (presumably) is going to explain at length why we should vote for him. No, I'm not joking.

     

    And yet, they still keep asking me for money.

     

    At this point, the ads are just becoming annoying. The other night it was:

     

    Ad for local democrat

    Ad for local democrat

    Ad against state bill

    Ad against local democrat

    Ad for (same) state bill

    Ad for Obama

     

    All in one commercial break. It's just tiring.

  8. We've (my roommate and I) been puzzling over this one for a while, and have run into a rather solid wall:

     

    We've been attacking this problem by dividing the sphere into infinitely thin "shells" and trying to come up with various to formulas to integrate over the radius.

     

    We've run into a problem on the following (I have no idea how to use LaTeX, so I'll do my best to describe):

     

    We are running into problems with writing out a function for pressure, as pressure is a function of radius of the entire sphere, and the depth that is being considered. The radius of the entire sphere, however, is a function of the pressure, as the pressure determines how much the iridium is compressed. So our equations seem to go in an endless loop, with one always turning up inside the integral of the other.

     

    Anyone?

  9. hi everyone

    1) Is relativity logically necessary?

     

    2) I mean, would it be possible for a God to create a universe with just Newtonian, and not relativistic, physics? If not, why?

     

    3) And if so, in what way would it be different from this universe?

    thanks

     

    I broke this down into numbers to make it easier for me to answer.

     

    1) This question doesn't mean much, as relativity is observed in experiments. It is far more than just a logical convenience. For example, GPS satellites must take into account that their clocks run slightly slower than ours, in order to produce accurate locations.

     

    2) Assuming your god was omnipotent, then anything is possible.

     

    3) See above.

  10. there would have to be some evidence that the light from at least those stars that are the closest to the globular center of the galaxy , have their light affected by any black-hole present

     

    but so far none exists

     

    but not only that , the light coming from the galactic globular center shows no signs of being affected either , by any black-hole physical dynamic consequences ,

     

    at all really

     

    Gravitational lensing?
