Why can’t satellites have an eject mechanism?

ISRO has had 3 launches this year of which two of them failed destroying their payloads completely. The spacecraft and satellites were all insured and hence there really was no huge monetary loss except of course for the Insurance company and I’m pretty sure the rates would have grown up for the jinxed GSLV.

Now the satellite is positioned to be ejected once it reaches a certain altitude. The only thing that needs to be added to this system is a parachute. The ground controllers could cause the payload to be ejected through a remote command. The satellite is thrown out with the capsule just like a Pilot ejecting a burning jet. After a few seconds a self-destruct destroys the rocket and the satellite floats down safely or is caught during descent by an air force mission. An expensive satellite is saved from sure destruction so many more man hours.

This could probably increase costs by a few thousand dollars but at $20,000 being spent on a Kilogram of payload it could be an awesome hobby project for someone in the space agency.  It could also prep us for a human launch to space. We’d only be rehearsing a much needed maneuver while saving priceless satellites.

How to optimize Firefox for a netbook ?

Netbooks have small screen and the same old story. We'll go through a few addons that'll turn Firefox 3.6 on your little netbook into a mean Chrome-beating super-optimized browser. At the end of everything, your browser will look like this.

You'll need to install the following addons to get your firefox to look like this -

1.Compact menu 2 : Replaces the default menu bar of firefox with a single button. {the button at the top left of the screenshot above}  

2.Hide Caption Titlebar Plus : Removes the annoying and useless titlebar from firefox.

3.Fission : Combines the progress bar and address bar a.k.a Safari, this allows you to do away with the status bar and obtain even more screen real estate. To disable status bar: Compact Menu->View->Status Bar

That's it, your firefox will look so much cooler and give you some much needed real extra real estate. You may also want to try the following addons.

4.No Squint: Set every page to be zoomed to a default value, the addon also remembers zoom settings for every page. This is extremely useful on a small screen.

5.Readibility: removes all unnecessary ads and pictures from a webpage and renders it into a magazine like format for easy reading.

Why do likes repel ?

This is more of a philosophical rather than a technical article.

It is strange that nature likes to keep the likes as far apart as possible. When it comes to electronic charges, the positive-positive or negative-negative combination repel each other with tremendous forces.  This force is around 9 Newtons inside an atom. Imagine an object that is a crore times smaller than your hair experiencing the force of a 10Kg bag!!! that's what is pushing apart the protons.

A similar effect happens with magnetic poles. The like poles stay away from each other while the unlike poles bond easily. Why does nature hate likes? The reason is simply that by keeping away likes and bringing together unlikes nature obtains a state of zero energy. A tranquil but useless and peaceful system is formed. The new system cannot do anything more exciting than being sterile.

A case in point is when likes can get together such as in the same atom that the repelling forces tried to separate them. By exchanging mesons the protons can interact with each other and become one formidable particle. This process is what creates all the different atoms and molecules. The protons act against natures tendency to separate them, get together and create the wonderful universe we live in. If they had bonded with an electron, they'd have just become a blob of energy that could never form the world we live in.

It is weird that only when things go against the norm and natural tendencies do amazing things begin to happen. A norm seems to be formed only because it is easy and requires minimal to zero expenditure of energy and time.
