<p>A free, open-to-all website that offers bright, interested students the chance to go beyond A-level physics. It’s called Schrödinger’s Cormorant (link: <a href="http://s-cormorant.com" target="_blank" rel="nofollow">s-cormorant.com</a>).</p> <p>It might be valuable for students who want to know more or who want to bring more of their A-level maths skills to physics. It could also appeal to those who are going on to study physics at university and would like to stretch themselves a bit in the summer break, to make sure their brains are in gear before they start.</p> <p>The key things about it are:</p> <p>It’s a free resource, open to anyone.<br /> It’s a maths-based approach, rather than popular science.<br /> The maths skills are all familiar to people who have done A-level maths (with a couple of extensions which are not a huge leap and are fully explained).<br /> It is structured so that the students do most of the work themselves, deriving and applying the equations. This should, I hope, lead to greater understanding and retention of what has been learned. It should also provide a sense of ownership and achievement (for example, they get to derive E = mc2 for themselves).<br /> All problems are presented in a step-by-step way and fully worked answers are provided.<br /> It’s structured as a logical progression through SR, the mathematics of waves, wave-particle duality and quantum uncertainty, all culminating in constructing the 1-D Schrödinger equation and exploring its use.</p>
