Everything is Communications

 #Draft Just about everything is communications. In engineering, what we do is describe a system using language, and implement it. Passionate engineers have a tendency to overengineer their projects, and for the same reason they tend to overcommunicate. Radio signals are also mostly used for communications, even though we ourselves are made of the very electromagnetic fields that are used to send radiations. In a way, we are all always connected and communicating with one another, just ever so subtly. That isn't actually very deep, as moving the electromagnetic field is not much different from moving our hands to establish contact. It's just that we are not used to thinking of the electromagnetic fields as part of our own bodies. Not finding the right balance in communicating is bad, both with people and in engineering. I am bad at communicating. Does that mean I'm bad at everything?

Energy Efficiency

#Draft Start by defining Power Density and Energy Density. Energy = VIt = Vq Describe Energy as the area of a rectangle with sides Voltage and Capacity or Charge (q=It) Contained. If this is the energy contained per unit mass of a material, this is it's Energy Density. Now, if we consider the energy utilized per unit time, that is Power Density. From this, you can know that for a given fuel, if its Power Density is Higher, its duration is lower. Now, this is the energy conversion for chemical batteries. We also often see the Power Density of Gasoline and other fuels mentioned, which unsurprisingly have the same units. In case of Gasoline and Wood, we take the Energy Density as the Heat of Combustion per unit mass. But Combustion is yet another chemical reaction, a redox reaction. Except that in this case, we utilize the heat instead of the flow of electrons. What are the other sources of energy? Another one would be the energy from motion (Wind, Water), Geothermal (Heat), Solar (Li...
