...energy from one place to another. In this short course you will discover the difference between transverse and longitudinal waves and gain an understanding of the properties of waves. You will gain an understanding of the process of echolocation and then undertake some online research to discover how bats use echolocation to locate their prey. You will also learn how...

...energy and to evade medication, by parasitizing the host’s cells. This makes it extremely difficult to use chemotherapy to target the virus itself, without impacting on the normal function of the cells within the body. However, extensive research and cutting-edge techniques have led to the production of highly successful drugs for specific viral infections, most notably...

...energy intensive to produce due to the materials that compose them. New ideas needed So what is the alternative to the current system? If car travel is going to remain common, perhaps we need to be smarter about how we build and use them. Our cars currently spend 92% of their time parked – and, when driving, most of their weight is used only to carry one person most of...

...energy. In a fraction of a second, the power radiated through these waves was more than ten times greater than the combined luminosity of every star and galaxy in the observable universe. This was a truly cataclysmic event a long time ago in a galaxy far, far away. In Star Wars Darth Vader tells us not to “underestimate the power of the dark side”. This amazing...

...matter and the remaining 65% being dark energy, with the latter two being called “dark” as we don’t understand what they are. Gravitational waves may now provide a tool with which to probe these mysteries in a similar way that X-rays and MRI have allowed us to probe the human body.
