Two weeks ago we embarked on a little adventure to find out more about quantum computing. Last week I was busy being bombarded by hail atop a mountain for four days. Today, we finally continue on our quest. The first one, not the camping.
The Earth sadly contains limited resources, one of which is fossil fuels. Fossil fuels are formed over hundreds of millions of years from the remains of dead organisms, which have decomposed under a variety of temperatures and pressures. We are using fossil fuels at a quicker rate than they can be formed naturally, so it doesn’t take a genius to figure out that we are going to run out of fossil fuels sometime in the near future.
In 1909, Ernest Rutherford theorised that the atom has its charge concentrated in a very small nucleus. Under his direction, Hans Geiger and Ernest Marsden conducted an experiment in 1911 to test his hypothesis.
