20240402 : Transducers...

Transducers Came across this word recently when I was reading something. Hadn't come across it for a while. Its a word and concept I learnt in my electronics course (either in 12th or my 1st year engineering course I am not very sure now) A transducer, very plainly speaking, is something which helps bridging the analog world with the digital world.  For example, take the very simple digital thermometer in our homes. They can't directly measure temperature in digital form. They have a transducer inside which converts the temperature from a analog/ real world scale to a digital world scale so it can be displayed. Generally speaking, we can say it helps bridge the real world with the digital world. When I had my stroke and I was told I will struggle for balance, I was not able to understand why. My understanding (based on my school learning) was that balance is maintained by the inner ears. Of course we were not told how and I never bothered to ask. I just knew balance was maintai

20220603 : power source?

I am an electrical engineer by training. So these are crazy thoughts from the electrical engineer in my mind 🙂 I have always assumed everything we think of is some sort of energy transformed into signals in the head. It might be whatever it is, but it gets converted to electrical signals in the brain. I guess that assumption got reinforced over time due to the prevalence of many sorts of scans that respond to some form of electromagnetic detection. After my stroke, I have realised everything below the neck is pretty much useless if these electrical signals dont pass through from the brain to everywhere else (actually everything above the neck on the face also!). The nerves are basically like wires - optic fibre grade++ and the brain is like a very complex super chip. The rest of the body with its 5 external senses - are basically sensors they have receptors (the sense organs) and transducers. They may be chemically or mechanically or thermally triggered or whatever triggered, but hav
