No. Godel proved that in any axiomatic system there exist statements whose truth values are formally undecidable. If the summary is correct, then this database would contain the whole of known mathematics and use automated theorem proving to do some advances.
There's a good reason for asking for the sum of the solutions to a quadratic equation. If the actual answers are given as one of the options, then the student can find the correct answer by plugging the solutions rather than solving the equation. And really, it doesn't add much to the complexity of the question.
It's too bad there's no modern equivalent of 3-2-1 Contact or Mr. Wizard's World. Both (and I'm sure some others) were good shows aimed at teaching kids science on a good level. Newton's Apple was excellent too, although it was not aimed solely at kids.
Bill Nye and Beakman (especially Beakman) were not as good because they were too interested in being flashy and funny and catering to kids with no attention spans.
I don't know if there's anything comparable on TV today.
Am I the only one who ever thought that maybe Han did mean it as a unit of length. If the Falcon travels at relativistic speeds, then the length contraction might squeeze the distance down to less than 12 parsecs.
I bought an ethernet card from 9thtee for my series 1 tivo several years back. At the time I couldn't believe I was actually spending $70 for an ethernet card, but since it allowed me to drop my phone line, it has saved me a lot of money.
Yes. That was called "The Mechanical Universe", hosted by David Goodstein. Where I lived it was on at 8:00 am. I discovered it in 8th grade when I was home sick for a week. After that week I recorded it every day and watched when I got home from school. I learned a lot of physics, science history, and math from that show. I actually learned to take derivatives of polynomials from watching the animations on that show. Now I'm a math professor, and my students look at me funny when I tell them that I learned the power rule from television.
Between Mechanical Universe and Mr. Wizard I probably learned more science than I did in school.
Digression: I remember being amazed by that experiment, and tons of other things that I saw on that show. I especially remember the demonstration where he used a vaccuum pump to suck grape juice up in a tube. It only went up so far, and he explained how the best vaccuum pump in the world wouldn't do any better because of the limited pressure at the bottom.
Good points all, but you can take off the "soon to be". The Hyundai plant in Montgomery has been operating for almost two years now, and has received the highest QA ratings possible.
(x+2)(x+3) the work was done in my head. My teacher hated that.
Your teacher must have been nuts. What type of work did he or she to see? Scratch work? (pointless) The quadratic formula? (overkill) I've taught math for nearly 10 years and I can't imagine wanting to see any intermediate steps when factoring a quadratic polynomial with two integer zeros.
It is poorly written, full of ad hominem attacks, lots of made-up grammar and word usage, wierd random abbreviations... it's scatterbrained, repetitive, and unnecessarily hostile.
Not to mention imprecise. In two instances the reviewer says
in order to solve an equation that has a square root sign within it, one has to square both sides of the equation at some time, and this doubles the number of solutions.
which is not true in all cases. Two examples are
\sqrt(x) = x, which has two solutions before and after squaring both sides, and
\sqrt(x)=10, which has one solution before and after.

Not to mention all the Tennessee Tuxedo fans, who are not going to be happy about it either.

That's not insightful. It's obvious.

I had an air-powered car years ago! :)
Yeah. Shouldn't it smell like blood?

10%? Where are you getting your numbers? According to the department of education, the graduation rate for 4-year institutions is about 56%.

They didn't have the empirical data that the author of this paper had.

Maybe it's just a slab of wood or something.
You mean like thisthing?

So what to tell the people in HR that are expecting resumes?
.pdf files.
Tell them to require that resumés be submitted as
You, sir, are incorrect. i is defined as sqrt(-1). See any algebra text or Mathworld for a reference.
Square-head screws are quite common in the USA.
Yeah. It was Gam. Also, it wasn't a cartoon, it was a live-action sci-fi show.
... it should have been reported by John Cleese, pointing to a model of the solar system screaming "This is an ex-planet!"

Interesting idea, but there aren't enough hard drives to do it.
