Nice, regnar998, and welcome to the forum!

Though... very few decimal places are needed in exams. I'd say minimum 2, maximum 10.

Nope, hard to find SATs papers before 2000. You can buy them, but otherwise I don't know where to get them, sorry.

The list is quite surprising. I did expect academic jobs to be up there, but it's also interesting to note that some of the most important services we require are a result of the worst jobs...

He probably means Quoted For Truth, though there is no quote, or he could mean Quantum Field Theory. Or other abbreviations.

Depends how you think about it, if you define a circular object as either a shape whose sides are negligible, or with ∞ tangents. You can state that two tangent lines are parallel, but that is because we only assume that there is a point on the circumference such that a straight line is existent. But if we think about a circle as having ∞ sides, then you *could* say that there is a point, ∞/2, which lies between two of the infinitesimal sides, but if we define this as a limit then we say that this is going to approach infinity. So what are we really saying when we say a circle can have ∞ tangents?

The concept is an interesting one, but as for the topic, you could say that a circle has either no parallel lines or ∞ parallel lines. Some people say that a circle has an infinite number of sides is just another proof that 0 ∙ (±∞) is an indetermination and not only 0. tongue
