5 Oct 2020: Activity - Molecular Dynamics Simulations. How can we understand what is happening at an atomic or molecular. scale? With computers, of course! In the 1950s, researchers developed methods to study atomic. systems by representing each atom as a rigid

11 Sep 2020: Bernoulli’s Principle. Bernoulli’s principle relates the pressure of a fluid to its elevation and speed. It is named after. the Swiss scientist Daniel Bernoulli who lived in the 18th century and did experiments looking. at how fluids moved. He

10 Sep 2020: Making Molecules. If we start off by thinking about making dihydrogen we know that, from much earlier in. school, each hydrogen atom has one electron and each would like two, giving a full first. shell. From our GCSE way of thinking of this we would

2 Nov 2020: Question 1. Using the two case studies presented above, or your own examples, consider how autonomy and. informed consent could have changed the way these patients were treated. Possible Answer. Alder Hey Children’s Hospital. Fundamentally a

6 Oct 2020: Worked Examples. Time Dilation. Imagine we had a spaceship which could instantaneously accelerate to whatever speed we. wanted (below the speed of light). Suppose we also found a star 10 000 light years (lyr) away which we wanted to visit. We decide
