    Gosh, you're sooooooo offensive - LOL. One of our poster friends (who shall remain nameless) likes to point out my grammar flaws, so it's a wonder I haven't been given the boot.

    Now, I do agree with Joe on all of this. It takes logic and mathematical aptitude beyond "basic math" to be successful at this kind of thing. Some people just "don't have it".

    Interestingly, I thought about #2 regarding the machines perhaps not all producing at the same rate. Then again, I thought about the inability to be able to literally wrap a ribbon around the earth - the other prob. It is important to know that some folks (especially the young) will focus on the "inplausibles" rather than the math component of the problems. And/or, they'll focus on the situational aspects of word problems, EX from shmoop.com/word-problems/translating-words-examples.html:

    "Lisa has five times as many books as she has CDs. She must be either over 45 or a librarian. Lisa also has 35 books. Okay, scratch that. She just hates music. How many CDs does she have?"

    That word problem was written to help such literal folks grasp the concept a little better. If one extremely leans on the literary, he/she will have a harder time taking the challenge of word problems. I have to admit, back in college I was taken aback at how astronomy was wrought with physics and word problems (substitution), yet I was yearning to see films about how the earth will die someday, and I wanted to see visuals of the formations of black holes and white dwarves. I never got to see those visuals. I got turned off on astronomy ever since.

    I think that was my comment that got removed. Not sure what I wrote that set off the "offensive" meters. As I recall, all I did was write about golf balls, diameters, and radii. If one can't talk about those in this forum, then I'll have to jump on the anti-PC bandwagon with gecroix, carlosrponce, JBG, Paul Hyatt, DottyOA, and the rest.

    Once upon a time in these forums, if you ran afoul of the content judges, they would at least send you a note that explained what was offensive. Of course, that was when the site was all free. I don't think we ever really understood how valuable this site was when it was wide open to the trolls.

    Sakes alive - Looks like someone got Comment Removed. Did someone try to slip in a math puzzle with "naughty" descriptions? OK, I can't resist -

    "A flat-chested woman goes out shopping for a new bra. She goes into shop after shop asking if they have a size 28A but she can’t find one anywhere. Eventually she tries her luck in a small lingerie shop run by an old deaf lady. ‘Have you got anything in size 28A?’ asks the woman. ‘What was that, dear?’ says the old lady. The woman lifts up her T-shirt exposing her breasts and says, ‘Have you got anything for these?’ The old lady peers at the woman’s ta tas and says, ‘No, dear. Have you tried Clearasil?’"

    Do some more, please. I just got lucky on the first 3.
    Don't give up on intuition ('gut feeling' in East Texas Pineywoods-ese).

    Kevjiang: you understood the whole intended concept of #3. I did not add the diameter to radius comment just to add a little last head scratch for purest like you.
    Also you found the one possible flaw in #2, there is an implied assumption that all machines are identical. If they are not identical there is not enough info to get an answer.

    Thanks for the comments. The only point I wanted to get across is that only logical thinking and doing the math consistently leads to correct answers. I've never had much luck using intuition in solving problems.

    Where are the crossword puzzles?

    Yes, I shall call upon 2 separate 11th graders and 2 separate 5th graders. One 11th grader - from a public school, the other from a charter or private school. Same for the 5th graders - one public, one private or charter. I can do a study to see which students answer the questions correctly - the ones from the charter or the public schooled ones?? Then, I can present the results to carlosrponce.

    OK. You have a point. How about if you go into your study and take the globe off the top shelf. Then, go up into your attic and pull out a roll of your holiday ribbon. Wrap it around the equator. Now, add a foot to it. You should have around 2" of slack around it. Unless you have enough people to help, you may have to just guess it.

    Or, you could just do the math :-)
    (or ask an 11th grade college prep student, or possibly some fifth graders!)

    #3 was inplausable: If you started to wrap a ribbon around the earth, let's say at the Equator in Congo Africa going from west to east, then by the time you got to Kenya you would hit water (Indian Ocean). So then you would need to embark upon a ship and lay your ribbon on the water while you're on the ship, starting from Kenya. Ribbon might stay atop water only if the sea waves are smooth enough to keep ribbon intact. You might hit a little land again in New Guinea, but you still have to contend with the water again before you finish the job on the west coast of Ecuador.

    LMHS at one time had the highest standards in the state of Texas.

    I only got #2 right. SCIENCE FAIL

    Not too hard.
    Being a LMHS grad was not an encumbrance 45 years ago...

    Great article. I missed one and three.
