I heard and read about people thinking that the Nerve Gear is possible. This has been in my mind since it has been mentioned in the shoutbox. We treated it as a joke. But I guess a little bit of basic lessons about how EM waves(in case you don't know, "Electromagnetic waves"), though I'm quite a beginner myself. So...from where do I start? Spoiler: Electromagnetic waves(definition) Electromagnetic waves(or EM waves, for short) are the combination of electric fields and magnetic fields(pretty obvious), variable in the time and having a typical wave-like movement. So far so good, right. EM waves have two particular values: wavelength and frequency. Based on those two values, the EM waves are distributed throughout this line called "electromagnetic spectrum"(don't need to link it. Google it) Let's talk about those values of the EM waves, shall we? Let's start from the wavelength. The wavelength is the length of the wave(duh). Means that is the value that defines the distance between the start and the end of a wave. Beware. Not for its actual length, but the distance between the peaks that define the wave. Next is the frequency. Frequency, in our case, is the value obtained by calculating the ratio between the speed of propagation of EM waves in vacuum space and the wavelength of the EM wave we have. The higher is the value of the frequency, the lower is the wavelength's. Ok. Math done. Let's go back to the electromagnetic waves. EM waves emit radiations, no matter what. But don't panic. Not yet. There are two type of radiation: Ionizing radiation and non-ionizing radiation. I do hope you did your homeworks, because I'm not going to spend 5-10 mins explain those two. Short story, EM waves up to the ultraviolet(including the latter as well) emit ionizing radiation. Anything below it is non-Ionizing. Now. Let's talk about the Nerve Gear. Spoiler: The Nerve Gear and the microwaves Based on what I read about the Nerve Gear, it is a helmet that reads the brain's electrical signals throughout the emissions of microwaves. Ok. Stop. Shall we talk about the microwaves, shall we? Microwaves are EM waves that emit non-ionizing radiation. So far so good, right? But, as far as we have progressed with microwaves, it's still a no go. Why? Remember what is currently the main function of the microwaves in commercial use?Good. Another point to notice: Microwaves operate on wavelengths from one meter to one millimeter, at the frequency range of 300 MHz-300 GHz(source: Wikipedia) Now...the neurons have a diameter that goes from 4 to 100 micrometers...not to mention, the ions that are involved in the synapses are way smaller. So...what's the point on what am I saying? The point is that microwaves cover a large area, if they can actually scan a brain(don't put your head in a microwave oven. It doesn't scan your brain. It burns it. Literally). Inside that area, however, there are already hundreds of electrical signals, each one different from the other. Well. I guess that's it for part 1. If you want to point out an error or add something else to the topic, comment down here below. For now, I'll just take a nap... For part 2...you'll have to wait for a while...maybe.
