    Is Transition to Advanced Mathematics Too Hard for Me?

    Ok I am enrolled in this Math class called "Transition to advanced mathematics". It has basically a LOT of proofing and set theory and such. Now of course, since i went through the whole modern day education system where you memorize this, memorize that, don't question this for the AP test... I...

    Should I Study Physics Without Taking a Class?

    Lately I've gotten an interest in physics. Theoretical Physics in particular, string theory, parallel universes, anything to do with things like that. Well, I would like to learn a lot more about physics, and perhaps even get a career in it. But, I don't know whether or not I should just...

    What is the difference between class and set?

    What is the difference between class and set? I have seen statements like "Let M be a class of subsets of X...", and it seems to me we can still do everything we like as though M is a set, and we are just avoiding the word "set" and replace it with "class". I am aware of the paradox "the set of...

    Which class of levers is the most 'efficient'?

    I am a dental student. I have noticed that dentists tend to say that Class III levers (eg. the human mandible) are "the least efficient type of lever." I told my friends that this was incorrect, because there is no more inherent energy loss in a Class III lever than I or II. The next day my...
