  1. Kids? on St. Louis Museum Offers Thrills, Chills, and Lawsuits · · Score: 3, Informative

    It boasts a five-story jungle gym with two real-life jets kids can climb on, an enclosed Monster Slide that drops riders the length of three staircases, and a rooftop Ferris wheel.

    Kids? Every time I've been there there has been a significant percentage of 20-somethings in addition to the little ones.

  2. Re:Too bad if the connection drops out... on UK Docs Perform First Remote-Control Heart Surgery · · Score: 1

    Really? I think I'd be okay with prioritizing traffic carrying life saving instructions...

  3. Re:Learn 2 math on At Issue In a Massachusetts Town, the Value of Two-Thirds · · Score: 1

    Significant figures are important. In this case, the 2/3rds rule, being a constant, MUST be taken to at least 3 digits. Otherwise why not just use 0.6 instead of 0.667

    Significant figures has absolutely nothing to do with it. They are for making measurements in a non-discrete space. All that's going on here is counting--there's no error, so no need for significant figures. Why on earth would you approximate a constant anyways? In any event, your rule for 'at least 3 digits' is completely arbitrary and useless. With enough votes, one could show that taking 'at least 3 digits' would still yield an incorrect result.

  4. Re:not quite 2/3 on At Issue In a Massachusetts Town, the Value of Two-Thirds · · Score: 3, Informative

    Further, 137/206 is still less than 2/3. So they in fact needed 138 to pass. This is why I tell my students to never use decimal approximations; simply use the exact number.

  5. Re:$100 ... PLUS $10-$15 Charger PER Title on Hard Drives Shipping with Star Trek · · Score: 1

    This diagram sums it up well.

    This is one reason I really like the Netflix Instant watch. 10-15 seconds after I hit 'play' (depending on download speeds), I'm watching the movie.

  6. Re:Buying a license for the movies? on Hard Drives Shipping with Star Trek · · Score: 1

    If you were going to throw these on a torrent, I recommend trying this BEFORE you format the drive.

    I meant download through a torrent of course :)

  7. Buying a license for the movies? on Hard Drives Shipping with Star Trek · · Score: 2, Funny

    So, can I buy one of these drives, reformat it, and then torrent these movies legally?

  8. Re:Red light cameras in St. Louis, Missouri on Red-Light Camera Ticket Revenue and Short Yellows · · Score: 1

    Care to share which municipality this was in?

  9. Re:if you're in the intersection and it's red on Red-Light Camera Ticket Revenue and Short Yellows · · Score: 1

    Maine driver's ed taught me that when turning left on a solid green non-arrow (yield to oncoming traffic), you are supposed to enter the intersection while waiting for the chance to go. If the light turns red, all traffic is stopped, so you have the right of way to GTFO.

    This is how I was taught growing up in Alabama. After moving to St. Louis though, I quickly learned to stop doing this. There are several lights around here timed so that the traffic going the opposite way will continue going (now with a green arrow) after your direction has a red light, leaving you in a precarious position if you have entered the intersection waiting to turn left.

  10. Re:If you can't handle calculus, science isnt for on Help Me Get My Math Back? · · Score: 2, Interesting

    As a calculus teacher, I can tell you this: you need skills in symbolic manipulation. Your algebra needs to be rock solid before you attempt college level calculus. In my experience, you need dozens of hours of practice before you get it. Buy an algebra textbook, and do every odd problem in every section until you are reliably getting everything right.

    I couldn't agree more. My better students are invariably the ones who can do basic algebra in their sleep. Those who struggle are those who never learned high school algebra (or god forbid, arithmetic) well.

    I spent several minutes deciding if this was a joke or not. And that fact makes me very sad.

  13. Re:I have an idea... on Perelman Urged To Accept $1m Prize · · Score: 1

    Where did I say what he should or should not do? I agree that people should leave him alone if he wants to be left alone. But running away and retiring because of a few bad experiences in the field strikes me as more of an overreaction than a logical consequence. As to your STFU comment, yes I am a mathematician and in my experience these comments about a 'cutthroat' environment are far from accurate. I'd like to see how many people who have experience in the field share these opinions.

  14. Re:I have an idea... on Perelman Urged To Accept $1m Prize · · Score: 1

    he was at the height of mathadamia (yay for made up words) and what he saw there was nothing short of cut throat...

    First, capital letters are your friend. Second, what experience do you have with 'mathademia' to characterize it as cut throat? If we're all out to get each other, then why are so few papers done by single authors these days? Perelman has some legitimate criticisms of a minority of mathematicians, but it hardly follows that those same criticisms apply to the whole of the profession, and hence that one should withdraw oneself from the community.

  15. Formal math? on BC Prof Suggests Young Children Need Less Formal Math, Not More · · Score: 1

    'Formal math'? Please. Kids are taught arithmetic and rote memorization. Then, in high school, they learn how to follow some algorithms and do harder computations. None of this has anything to do with formal math or any sort of thinking, and it's no wonder they think it's boring.

  16. Change the name on House Passes Massive Medical Insurance Bill, 219-212 · · Score: 2, Interesting

    Can we please stop calling it health 'insurance' now, since with this legislation it has nothing to do whatsoever with the term?

  17. Re:RTFA on Computer Science Major Is Cool Again · · Score: 1

    Programming is to computer science what algebra is to mathematics.

    Hey, I'm an algebraist you insensitive clod!

  18. Re:Paternity Leave on Women Skip Math/Science Careers To Have Families · · Score: 1

    The mostly arbitary decision that women have to stay home with the kids

    I'd hardly call it arbitrary at all. My wife is simply better than me at taking care of kids. I don't think we're unique either.

  19. Re:Was decent, once upon a time on The Last Will and Testament of Circuit City · · Score: 1

    I worked there for a short time as a kid and the EWPs (Extended Warranty Plans) are pushed so hard it is amazing. Customers are hounded for all their personal details and the staff are trained to tell them it is for warranty information - whether an EWP was involved or not.

    I was in Radio Shack this week, and they tried to sell me some sort of Product Replacement Plan/Extended Warranty on a $3 power supply.

  20. Re:Same side on Nuclear Subs 'Collide In Ocean' · · Score: 1

    What retard modded this Insightful? Funny, sure. Even Redundant. But FFS, Insightful?

    Funny doesn't contribute to karma, so it's common for mods to instead use Insightful, Interesting, or Informative. I usually use whichever is funniest in the context of the post.

    Now why is this modded funny? It's downright informative, interesting, or even insightful.

    If obscurity is not a chief objective you could latinize the server's functions. Mailicus, Proxius, Validicus etc..

    I started naming my Linux boxes sequentially after Roman emperors. The first few were fine, but now I'm on Claudius. I'm afraid to buy another computer, as then I'd have to name it Nero and I really don't want it to burn my house down.

  22. Re:Netbooks are the future. on Second Netbook Wave Begins · · Score: 1

    A five-hundred dollar, three pound netbook with a ten inch screen, over five hours of battery life, and an integrated 3G wireless card would make regular laptops obsolete for most consumers.

    That sounds a heck of a lot like the EeePC 1000.

    I got my start programming a TI-89. First in TI Basic, then on to C with tigcc (http://tigcc.ticalc.org/). It has the advantage that kids can drag their calculator around and show their friends the stupid little game they made.
