It's all Engineering.. isn't it?

I vividly remember the lines of my favorite App-Mech teacher back in the days of first year of engineering -

"सुबह नल खोला तो पानी आना चाहिए, That is called engineering"

When Prof. Dixit said this in his (in)famous mechanics class, what he meant is that an engineer's job is to make things work! However trivial they may be, however unimportant they might sound. It takes engineering to make things work in this world.

• Rotate lever of a door knob & give a gentle push to your heavy door, it opens smoothly! Not many will notice this right away, but it takes clever use of appropriate fulcrum point to multiply the mechanical force which moves your door like it's a small drawer.
• Press few switches on the wall, whole room gets illuminated with bright light, temperature of air gets controlled, your favorite music starts playing & what not! Correct use of electrical engineering to wire up your house connecting all kinds of electrical gadgets & instruments makes this possible.
• Open a tap, water should start flowing out of it at next instant! Sounds simple? but it takes careful study & flawless design of pipeline system - fluid engineering!
• A couple of clicks on computer and the knowledge of whole world is at your disposal through internet! A revolution brought to you  by computer & communication engineering.

And the list could go on & on & on.... giving much more significant and complex examples from everyday life. These small to big examples from our daily lives prove beyond any doubt that we live in a world full of engineering marvels. We take their help to ease our life, we rely on them, we need them, we survive on them. It is near to impossible in current times to imagine a life without any engineering involved in it. I think we were meant to discover all this, learn from nature it's basic rules and ways of employing them to solve our problems.

I often wonder if these rules of engineering also apply to human behavior? to our actions/reactions? to our instinct? I guess they would..
