...energy it generates. You will learn about how it can affect your health and well-being, and how different climates design their homes differently to maximise the benefits of the Sun...This free course, Seeing the light, will teach you about how the Sun affects your home, both in terms of light and warmth and the energy it generates. You will learn about how it can affect...

...energy rate, cold forming technique that reshapes metals without physical contact. When an electric current generates pulsed opposing magnetic fields near the metal, a controllable pressure is created...Three main concepts [Images to demonstrate 'Magneform (electromagnetic assembly and forming)' - see article ] Bulging or expansion ring [Images to demonstrate 'Magneform...

...energy into molten material (1/5 of the energy of plasma arc and 1/9 of the energy of flame processes). Although plasma arc has a high capital cost and high operating cost, and requires complicated support services, it is the most versatile of the thermal spray processes, giving excellent coating properties with almost any material. The high operating temperatures...

...energy into electricity, heres an explainer on how a battery works...What is an electric current? Within every atom there’s a tiny, positively charged nucleus surrounded by a number of even smaller, negatively charged particles called electrons. The electrons each carry the same amount of negative charge. The charge on the nucleus is equal in size to the total charge of...

...energy source at its heart...The field of active galaxies is recognised as one of increasing importance. But how do we know there are different kinds of galaxy? What are active galaxies? How are they powered? This free course, Introduction to active galaxies, examines the different types of active galaxies and looks at the crucial role of the active galactic nucleus and...

...energy and sustainability, electronics, or mathematical methods. Alternatively, you may wish to investigate our BSc (Hons) Natural Sciences degree, which allows you to choose a general science study route or to follow a more specialised route in biology, chemistry, physics, Earth sciences, environmental science, or planetary science. If you already have an undergraduate...
