Optics, the understanding of light.
Optics is all about light. Look, I have not really read the classical stuff, so it might be long winded, but it won't be that long, as usual.
With optics, you take light and, for example, with a laser, you guide the light or create a light source to be focused out of the device. If the device was to give off, for example, a lot of different lights, like a computer monitor, then it would merely be giving off different densities of light. The light we see is actually different shades of grey, where the actual density shows the shades, as density is where the shades come from. This is true because the frequency, as it is called in modern science, something I am trying to change to density, as it holds with other branches of science in a universal theme, will result in the shade having a different colour. But, back to 'greys...'
This grey thing, it sounds silly at first, but really, if you open your monitor up, you will see a lot of different pieces of silicon for conducting electricity. These circuits will push energy off them, giving off the light effect, and, if they are tuned sensitively enough, will give off a wider variety of colours. This will result in 'better graphics,' of course, with more focus on variety, and, detail. We now understand how a V.G.A. monitor works, yes?
So, if we were to observe that, we could easily understand that we could simplify the monitor's circuits to give off similar graphics for a cheaper component with a simpler mould, leading to first generation designs of other types of monitors, yes? For example, we could bring in a flat pane of silicone, where the images could form based on the light being given off like a sound blaster with a diaphragm, where a little hammer hits the certain notes behind the speaker for the right sounds. This would be where there could be pins stuck into the silicone with them giving off programmed pulses of energy, where they would produce 'colours' or 'light' due to the energy interacting with the silicone.
I calculate this would require a cheap silicone base screen, a few rudimentary pins, and a power source and safety screen for not being electrocuted, maybe a non conductor like plastic? This first generation monitor would be easy to assemble and cheap to experiment with.
Acoustics - sound engineering.
I have briefly touched on this in the past, and, have found things I have already forgotten. But, from what I can remember, the acoustics or sound engineering of the computer or electronic device, as, that is what mechatronics is all about, is down to the sounds being put through a hammer to a piece of cloth like material that is 'hollow.' This gives off a sound, from mechanical stuff, so it creates sounds based on where it hits the cushion, like a piano, okay?
With this in mind, we could maybe improve the device to become 'analogue.' I prefer analogue to digital and if you compare the quality of a analogue first generation photograph to a digital one, you will see they both have their strengths - one working in a image shock photo, and, the other working on pixels, of course. Is there no other way... wait, I digress from our focus, on sound engineering!
So, with that in mind we could produce good quality sound with the same principle we made our monitor with, a lot of cushion with pins through them, giving off vibrations... or, we could maybe upgrade this for sound engineering by putting a lot of pins into the piece of supple plastic that will be layered, to give off 'echoes?'
If you enjoy my lessons, thank you. If you find them wanting, please remember I am trying to give a firm foundation for understanding all forms of various fields at once, especially for non first English language speakers.
