...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...

...oxide. A sunscreen contains chemicals that absorb the energy contained in the ultraviolet rays and reflect it away as lower-energy long-wave radiation, which is emitted as heat. [sun block versus sunscreen] Final thoughts A good way to limit exposure to UV light is to avoid being outdoors in sunlight too long. UV rays are most intense between the hours of 10 am and 4 pm....

...solar system move, then you would need to put in a mathematical description of gravity, and then you could set your solar system going and watch things moving. And you wouldn’t need to describe all of the autonomic physics that gives you the structure of each individual planet. For your model of the solar system you could have a rather simple description of gravity, and...

The best thing about being an engineer Transcript. I never feel alone as an engineer. No matter what’s happening, something, you need something done, it will get done. And it will get done by...

Combining laser and gas tungsten arc (GTA) welding can produce deeper weld penetration...[Images to demonstrate 'Laser beam welding' - see article ] A high energy laser beam is focused onto the surface to be...

...energy stream of ions that penetrate the surface. This is not a diffusion process. Once impregnated into the surface, the ions (usually carbon or nitrogen) lose their energy and stop moving. The compressive stresses generated in the surface layers improve mechanical and fatigue properties, as well as corrosion and wear resistance...[Images to demonstrate 'Ion...

...energy) of alpha particles produced by radiation is specific to the isotope that emits them and leaves a kind of signature, with which the original isotope can be identified. A sample of fluid suspected of containing polonium is dried onto a surface and the energy of the emitted particles is measured. The number of particles with a particular energy is directly...
