What does it really take to get into the Ivy League? Grades This is the foliage of destiny. So, you want to go to an Ivy League college for undergrad? The only problem is, so do lots of other kids. The Hungarian army officer and mathematician Johan Bolyai wrote to his father in in excitement at his mathematical breakthrough with regards to the parallel postulate.

The result was indeed, a new universe from nothing. If a line crossing two other lines makes the interior angles on the same side less than two right angles, then these two lines will meet on that side when extended far enough. Collectively these assumptions lead to the basis of numerous geometric proofs — such as the fact that angles in a triangle add up to degrees and that angles in a quadrilateral add up to degrees.

Gerolamo Saccheri A geometry not based on the parallel postulate could therefore contain 3 possibilities, as outlined by the Italian mathematician Gerolamo Saccheri in This is the hypothesis of the obtuse angle — a geometry in which the angles in quadrilaterals add up to more than degrees.

This is the hypothesis of the acute angle — a geometry in which the angles in quadrilaterals add up to less than degrees. Adrien Legendre Mathematicians now set about trying to prove that both the cases 2 and 3 were false — thus proving that the Euclidean system was the only valid geometry.

The French mathematician Adrien Legendre, who made significant contributions to Number Theory tried to prove that the hypothesis of the obtuse angle was impossible. His argument went as follows: From the sketch we will have lines A1B1 and A2B2 and subsequent lines equal.

These have 2 sides the same. In other words, the distance starting at A1 then travelling around the shape missing out the bottom line the yellow line is longer than the bottom line green line. Therefore as n tends to infinity, this inequality must be broken.

In the s however, mathematicians including Gauss started to wonder what would happen if this assumption was false — and along the way they discovered a whole new branch of mathematics. They discovered non-Euclidean geometry.

Through his collection of books, Elements, he created the foundations of geometry as a mathematical subject.

Indeed you might find it slightly depressing that you were doing nothing more than re-learn mathematics well understood over years ago! The 5th however drew the attention of mathematicians for centuries — as they struggled in vain to prove it.

This might look a little complicated, but is made a little easier with the help of the sketch above. Therefore we have the lines L1 and L2 intersecting.

Lines which are not parallel will therefore intersect. At most one line can be drawn through any point not on a given line parallel to the given line in a plane. In other words, if you have a given line l and a point Pthen there is only 1 line you can draw which is parallel to the given line and through the point m.

Both of these versions do seem pretty self-evident, but equally there seems no reason why they should simply be assumed to be true. Surely they can actually be proved?

Well, mathematicians spent the best part of years trying without success to do so. Why is the 5th postulate so important? Most mathematicians working on the problem did in fact believe it was true — but were keen to actually prove it.

As an example, the 5th postulate can be used to prove that the angles in a triangle add up to degrees. This is the familiar diagram you learn at school — with alternate and corresponding angles. If we accept the diagram above as true, we can proceed with proving that the angles in a triangle add up to degrees.

Once, we know that the two red angles are equal and the two green angles are equal, then we can use the fact that angles on a straight line add to degrees to conclude that the angles in a triangle add to degrees. But it needs the parallel postulate to be true!

Hi I’m currently going to into my senior year of high school and I really want to go to Columbia or any Ivy League for that matter but I am a little worried I won’t get in because my freshman year of high school I got a D in geometry and a C+ second semester.
