    Computable Normal Numbers: Is There a Known Answer?

    Very few of significance, I expect. (In fact, it's conjectured that most of the computable mathematical constants we're familiar with pi or Euler's number are absolutely normal.)

    Finding the Cardinality of Set C: A Problem in Subsequence Coverage

    It may make sense to look at the union of each subset of K tiles, and then take power sets of their union.

    Why doesn't an inductor act as a closed circuit to AC?

    You can think of the inductor as working a bit like inertia in stream of fluid: when the rate of flow changes, it 'resists' the change. It creates a voltage difference proportional to the rate of change in current - so when the current is constant then there is no voltage.

    Password retrieval questions seem less than ideal.

    I C&P'd stuff from the sidebar into the 'random question' thing, and it told me it was incorrect. For example, the question about what PF values matches up pretty nicely with that first sentence, but copying the words doesn't work.

    Increase in rote memorization in current students?

    It's not just one year, and it's not just the Chinese. If the SATs weren't such a joke they could be thrown into the same category. http://en.wikipedia.org/wiki/Abitur

    How can we maximize energy storage for a pullback mechanism vehicle?

    How big is the vehicle going to be? Does it have to turn? Depending on scale, I think I'd be looking for a system with a spindle and a dropping weight.

    How can we maximize energy storage for a pullback mechanism vehicle?

    Are you going for speed or distance?

    Closed cycle rankine cycle engine using alternative fluid.

    Why not just use a stirling cycle engine instead? If you're skirting close to the boiling point, steam engines tend to have problems with condensation. Carnot himself basically said that there's not a whole lot of benefit to using fluids other than air and water.

    Designing a Bicycle Front End: Rake and Trail Considerations

    Depends on what you're doing. People write books about that sort of stuff. Tony Foale's page has some more discussion.

    Can Drawings or Favors Ever Count as Real Payment?

    There was a guy who made (one sided), highly detailed paintings of US currency, and offered them in lieu of payment. There was an article in a local paper about him.

    Male-Female Strength/Wrestling Question

    It depends on the style of wrestling. There's a pretty huge variety out there. Superior technique and timing can overcome size and strength advantages in most forms of wrestling. The MMA circuits have a number of 'giant' guys that regularly get beaten by guys that are much smaller than...

    News What are the Key Factors for Victory in the 2008 Presidential Election?

    "It seemed they had an agreement until McCain showed up. Is this an example of McCain snatching defeat from the jaws of victory?" Honestly, McCain's campaign is looking pretty desperate. As such, a gambit like this isn't really that inappropriate. I think this will be remembered as the...

    How to Eat Cheap/Free - 5 Ideas to Stretch Your Food Budget

    Rice and Lentils/Peas/Beans is probably as cheap as you're going to get. If you buy good-sized dry bags I think you can still get them for something like $0.50/lb. You're also going to want roughage and vitamins, so veggies - I'm not sure what's cheap for you there. Stinging Nettles are...
