>* 2 Safeties
If you've figured out there are two safeties then this implies that the defense is looking to take away big passing plays but give up the middle of the field.
2 safeties is pretty standard and is just as much a run stopping defense. For example the corners in man on the exterior with the safeties in man on the interior is a run stopping defense. Backers often cover the apex or a safety roles to the center taking away the middle. Nice overal explanation but the strategy in football is to "show" one thing and do another which is why a pre-snap read only goes so far.
Sketch Up would not be a good option because it produces mesh models which look like garbage when printed, a good low cost Nurbs modeling software that produces true curves for digital fabrication would be Rhino 3d. The educational version of Rhino is $195. http://www.rhino3d.com/
Edit: and if you want to make your cups parametric like the examples the grasshopper plugin for Rhino is the way to go http://www.grasshopper3d.com/
If you are seeking a masters in CS most universities are only looking for programming languages, computer architecture, data structures and one algorithms course. These are the prerequisites for most courses.
I would also add that school affords one with the ability to focus full time without the distarctions and fateague of a full time job (especially if the job is in a non related field). This is imparative to those who haven't been programming sense age 12 and are relatively new to the space. Everything is "easy" when you know how to do it. I guess the point I'm trying to make is that the value in higher education extends beyond its curriculum and that value is entirely dependent on the individual.
The statue of liberty/wtc is somewhat of a silly point of comparison for national debt but grounding numbers into something familiar or in this case physical objects is quite telling for most people. Even if your point of comparison is "the federal budget/GDP/world GDP/debt of other large nations" it goes back to the same issue where you are comparing large numbers to other large numbers which is meaningless to most people(outside of HN). I wouldn't use this type of visualization to brief congress but it is telling.
I was completely honest scoring 16,000, English is my one and only language. Depending on your field/background you could understand more words than this test suggests. Looking up the words that i did not understand coupling them with there relevance and the shear volume of test words or lack thereof makes this test inaccurate in my mind.
