  • "What we can conclude is that a baby's autonomic nervous system is able to sense the electrical environment and it seems as though a baby is more relaxed when grounded,"
  • redesigning incubators to ground babies and cancel out the electrical field

    I think a possible research idea could be redesigning NICU incubators to allow for less electromagnet interference with the babies with the use of grounding.

    Interesting, for sure. Two things... the actual measurements they made on children (skin tests, etc.) are a no-go for us. I'm not sure what our model system could be for checking the electrical outputs of whatever design changes were made. We would need to know a lot more about the current setup in NICUs. There is no doubt a lot of design in how things are currently set up. Essentially: why things are set up the way they are right now? You would have to know every variable currently considered, and then look for spots where simple changes can be made. Second thing: go back to the ISEF categories in Engineering and check out how those projects look at the national level. Just go get a feel. Engineering is a bit different from typical "hypothesis testing" seen in most natural sciences. Very cool, but different. Give it a look.

      It would be fascinating to find something that could prevent that static electricity, especially on pets. I feel like there are lots of possibilities with this.

      We find that when a falling water droplet spreads on the PTFE surface, it bridges the originally disconnected components (the PTFE/ITO and aluminum electrode) into a closed-loop, electrical system Interesting.

    Interesting to see a different method on creating power out of water. I kinda of want to look into the science of water.

      Magnetoencephalography is a technique used to measure the magnetic fields produced by electrical activity in the brain. It is a non-invasive method that can provide high temporal and spatial resolution of brain activity. In the context of the research paper, the authors mention a study by Strauss and Dehaene that focused on electro- and magnetoencephalographic responses to spoken arithmetic equations during wakefulness and sleep.

  • They hypothesized that the mesoscale environment indirectly influences CG lightning polarity by directly controlling the storm structure, dynamics, and microphysics, which in turn control storm electrification and ground flash polarity.

      I guess that would make sense considering the fact that the electricity in the air before a storm is active.

  • 1’s are literally thrown away, and that wasted energy is dissipated as heat.
    • Xander Kleiber
      Xander Kleiber on 05 Jun 23
       
      In logic gates specifically, because there are cases where a 1 goes in and a 0 can come out, that 1 (directly represented by electrical voltage) gets wasted in the computation and is released as heat.
  • the inputs are 1-0 and 0-1, and the output is 1-0. That setup is wasteful: An incoming 1 is lost during the computation. The researchers solve that problem by retaining the extra inputs as “garbage bits” that carry useless information (see the bottom example). The 1-0 order doesn’t matter, but now the number of 1’s is preserved after the computation.

      Seems like a great way to solve the issue. However, I don't see anywhere else in the article any sort of actual circuit design/implementation of said solution...
  • On the energy front, the goal is to conserve all information—not just the 1’s but the 0’s as well. Their approach is based on “reversible computing,” an idea first proposed in the 1970s.

      Expanded upon later.

  • “If you can play everything backwards, then no energy has escaped during your computation,” says Demaine.
    • Xander Kleiber
      Xander Kleiber on 05 Jun 23
       
      So in reversible computing, if an algorithm can be reversed, that means no information (and therefore no 1's, or measures of voltage) are wasted, resulting in an even lower production of waste.
  • Xander Kleiber on 05 Jun 23
     
    Overall, this seems like a decent course of study. After all, mentioned throughout the article is something called "Landauer's limit," which is a limit to the efficiency of computing devices using the current, wasteful methods. Also mentioned briefly in the article is that we are continually getting much closer to this limit. This makes it a timely issue, along with the fact that not many people have elaborated on its implications or tried implementing it.

    This is really interesting... though I'm sure I would benefit from a back-and-forth conversation to make sure I'm understanding what I think I am.
