Welcome to our first Unity game! The idea of this puzzle game is very simple – using the integers given, arrange them as fractions such that they add up to 1. For example, given the integers:

1 1 1 1 2 4 8 8

How can these be arranged as fractions so that they add up to 1? Here is a solution:

1/2 + 1/4 + 1/8 + 1/8 = 1

Of course, this was an easy example. Our first puzzle is a little more difficult, but the difficulty level is hard to gauge – that is why I am asking our users to comment on this puzzle and to let us know if it was too easy, too hard, or just right.

Our first Unity puzzle integers are:

1 2 3 5 9 10 15 30

Using the integers given, arrange them as fractions such that they add up to 1. The answer will be posted in our next Unity puzzle. Thanks for playing!

Gravitational waves were first detected on September 14, 2015 by both of the twin Laser Interferometer Gravitational-wave Observatory (LIGO) detectors, located in Livingston, Louisiana, and Hanford, Washington. These waves were generated by a pair of black holes that orbited each other at very high speeds – close to the speed of light!

So how are these waves generated? Steve Mould has made a model that (very impressively) demonstrates how these gravitational waves were generated:
