Is our brain designed for fourier analysis ?

I am 25 years old and have seen many ups and downs in life. Not just when it comes to mood, but also several other things like social life, interests in different subjects, the way I treat different aspects of life, etc.

Now more often than not, and as I grew , I have been able to sense sinusoidal ups and downs . Don't ask me which ones and how, but I have been able to also sense that the factors that I used to perceive when I was younger which have other forms of ups and downs like square, triangle, irregular, actually don't exist as themselves , but are further broken down to other factors that have proper sinusoidal ups and downs.

That leaves a question in mind : Does everything that happen actually just a combination of several different sinusoidal waves, which control "Macro" things in our life? Is it just that our brain actually keeps doing Fourier analysis ? Is our life actually God's "listening" process of some "music" that is being played? The music that is constituted by all those "ups and downs" that we feel ?

Another question: What are emotions? How do they affect ? Who induces "Interest"s in particular persons ?

The greatest magic show.

A pile of mud. Lifeless, inanimate, simplistic pile of mud. Lying on the ground or flowing around at the whim of the wind's and gravity's wishes. Stones, rocks, rivers. All behaving exactly as simple physics could explain.

Now imagine a part of the pile of the mud thinking for itself, being able to control where it goes, or may be collect water from the ground, energy from the sun, and channel, store it for future. Now wouldn't it be the most amazing magic trick you could see?

The magic pile of mud that could be you, your pet, the moss growing on a stone in your backyard, the snail feeding on it, the bird high up in the air planning to do a "drop" on your car you just washed.

This magic show is called "Life". Life is the most amazing magic shows you can witness. Don't miss it ! And please don't mess with it.

Safer rockets

Billions of dollars are spent every year to build rockets, make their payloads, and also attempts of making them safer.

But till now the most valuable(sometimes even invaluable) part of the rocket: the payload module is still extremely close to the rocket (The part that usually explodes and causes disaster). Why not make sure there is a large distance between the module and the rocket like this? :




The picture is a quick sketch and ugly. The main idea is to add a long tubular frame between the rocket module and the payload module. The distance should be enough to protect the payload from extensive damage , even if the fuel bursts into flames.

Enhance Knowledge channel experience with wikipedia.org

Especially if you are seeing Discovery, National Geographic, or such knowledge channels, keep Wikipedia ready for action. When I was watching Future Weapons today, I learnt about Bangalore Torpedo, Blade, Machine gun ,etc.
