...Energy Who'd have thought Albert Einstein could make a mistake? Dark Energy explores how Einstein was right all along about the expanding Universe. We never should have doubted him. Black Holes Is it possible to make your own black hole? DIY experts take note. Taking a Galactic Census How do you take a census in space? Find out how it is possible to produce a 3D map of...

...Solar System. We know that the Sun is orbited by four close-in, rocky planets (Mercury, Venus, Earth and ars), then there is an asteroid belt containing millions of small rocky bodies. Further out still are four gas-giants (Jupiter, Saturn, Uranus & Neptune) each accompanied by dozens of rocky moons, and then another region containing millions of icy bodies, known as the...

...solar flares coming from the red dwarf star (a small and relatively cool star). Such stars are indeed prone to this type of activity, but the researchers say the radio pulses are unlike anything ever seen from other similar stars. Perhaps more likely is that the signals originate closer to home – arising as interference from a high altitude, Earth-orbiting artificial...

...energy. Scientists call this the ‘Von Neumann bottleneck’, and it is one of the main reasons AI is so power-hungry. The logical solution? Build hardware that actually works like a brain, not just software that thinks like one. Neuromorphic computing Instead of running brain-inspired software (ANN) on conventional hardware, neuromorphic computing is a hardware...

...energy. It is vital in the manufacture of many modern materials. But the worlds supply of oil is finite, its price is unstable and our reliance on oil has damaging environmental consequences. This free course, Living without oil, explains why developing alternatives to oil is an essential and urgent task for humanity...Crude oil is currently our most important global...
