What is a triangular number?
A triangular number is a member of the series which is calculated as follows: t(1) = 1 = 1 t(2) = 1 + 2 = 3 t(3) = 1 + 2 + 3 = 6 t(4) = 1 + 2 + 3 + 4 = 10 and so on. t(n) = 1 + 2 + 3 + 4 + ... + n Fortunately, there is a simpler formula t(n) = n*(n+1)/2 To see why they are called triangular numbers, consider the following pattern: Put one mark in the middle of a line. Then, in the line underneath, put 2 marks. You now have three [=t(2)] marks in the form of a triangle. x x x In the next line, put three marks. You now have six [=t(3)] marks in the form of a triangle. x x x x x x and so on.

What is pyramidal number sequence?
It is a sequence in which the numbers represent the number of spheres in a pyramidal stack of spheres. There are a number of possible configurations for stacking spheres - a visit to fruit stalls may show you options. The square based pyramidal numbers are given by the sums of the first n square numbers. So U(1) = 1^1 = 1 U(2) = 1^2 + 2^2 = 1 + 4 = 5 and so on U(n) = 1^2 + 2^2 + ... + n^2 = n(n+1)(2n+1)/6. However, there are also triangle based pyramidal numbers and hexagon based pyramidal numbers, since these configuration also give stable stacks.

What is a crystal's shape and what determines a crystal's shape?
A crystal is a mineral where all of the atoms are in a row, this is what makes it kind of clear. What determines its shape is the amount of space it has to form in and will usually have triangular pyramidal edges.
