  • 17:1917:19, 9 September 2022 diff hist +377 N Glossary:Memory effectCreated page with "The memory effect is the property of some types or rechargeable batteries to "remember" if they have frequently been only partially discharged. They can then become reluctant to deliver more charge in future. The cure is to fully dischage then fully recharge them periodically. NiCd batteries are particularly prone, and NiMH rather less so." current Tag: Visual edit

  • 16:4316:43, 9 September 2022 diff hist +563 N Glossary:Fibre OpticsCreated page with "If you feed light into the end of a thin glass or transparent plastic fibre, it will be constrained to the fibre by total internal reflection and emerge at the far end, even if the fibre is many miles long. Furthermore, with high quality fibre the losses can be much less than with an electrical cable, and light can carry vastly more data than an electrical signal. Fibre optics is the application of this principle, together with the ancilliary lasers or Glossary:LED|LED..." Tag: Visual edit
  • 16:2716:27, 9 September 2022 diff hist +537 N Glossary:WaveguideCreated page with "At the highest frequencies (GHz and above), every bit of wire acts like an aerial, so you can no longer rely on sending a signal down a wire and expecting it to get to the other end. So why not let it do its thing? Feed it into an aerial at the end of a copper pipe and it'll bounce all the way down the inside and come out at the far end. This is what a waveguide is. A microwave oven contains a waveguide to feed the energy from the..." current Tag: Visual edit
  • 16:1416:14, 9 September 2022 diff hist +677 N Glossary:Quantum ComputerCreated page with "Don't worry, you may never have to fix one of these. One of the predictions of Quantum Mechanics is that sub-atomic particles can effectively be in more than one state at a time. In theory, you should be able to use this property to build a computer that explores many possible solutions to a problem simultaneously rather than trying them one by one, as a normal computer would. This could be really neat for cracking cryptographic codes, or w..." Tag: Visual edit
  • 15:5415:54, 9 September 2022 diff hist +322 N Glossary:Quantum MechanicsCreated page with "Quantum Mechanics (or QM for short) is the counter-intuitive theory of how things behave at the atomic and sub-atomic levels. It has passed every test physiscists have thrown at it, yet nobody understands it, only how to use its predictions to design lasers and silicon chips and al the modern gadgets that depend on them."
