This is one of the n topics (why do we have 2 eyes, gravity, speed etc..,) we discussed yesterday.. so boys had to say that gravity does not effect a bullet fired from a gun, because the speed is so high that gravity does not act on it.. so the bullet travels horizontally.. (does this mean it escaped the gravitational force?).. but
the fact..
A bullet is a projectile and as such, its horizontal motion is unrelated to its vertical motion. Just because it is moving rapidly in the horizontal direction does not mean that it will fall any slower than an object that is not moving horizontally. They still fall with the acceleration due to gravity
(
Here is a excellent example given by Joy Wagon... The Monkey and the Gun
We can't see the fall of a bullet because it happens so quickly that your eye cannot catch it. The trajectory from the point where the bullet comes out of muzzle and the point it hits the target is not horizontal but a curve (practice makes your brain calculate this gravitational pull, similar to a ball you throw to hit a target).. so what is it all proportional to ? is it time??
Here is a experiment conducted by B.E. Spencer... A Closer Look at Trajectories
Newton's first law says that the bullet will continue to travel on a straight line forever if no forces act upon it. But the bullet falls, so there is a pull and it is gravitational force which is pulling it..
So.. when you get to shoot something.. make sure you keep in mind that gravitational force acts on the bullet and shoot accordingly..
Updated after the first comment :)
Sights on guns are used to adjust for the effects of gravity on a bullet. When you set the sights on a gun, you must set them for the range you are likely to be shooting from. Basically what you are doing is adjusting the "Line from sights" to cross the "Bullet path" at the distance you will likely be shooting from. Beyond this length, your bullet will hit low, closer than this length, your bullet will hit high. This also only sets your gun correctly for level ground. If you shoot down from a hill, your bullet will hit high or if you shoot up a hill (dangerous practice) your bullet will hit low.

Myth: Bullets fly so fast that they are unaffected by gravity.

How does google earn money and How can I earn from them?
The following question How do these earn per click ads on google and other sites work?
triggered me to write this entry..
Anyways... here you go..
Google search engine is the main source for google to earn revenew. Your immediate question may be.. how does it earn when we do not pay anything while we search.
Google.com earns most of its revenue by allowing other website owners to advertise on their search result pages (these are the same ads which you see sometimes on the top of al results or mostly on the right side as Sponsored Links). All this is managed through a program they call Adwords. Now if you want to advertise your site on google by paying them anywhere between 5 cents to $30 per click to your website from google then all you need is to signup with google adwords.
Google does not post your ad for every result,
You create your ads
You create ads and choose keywords, which are words or phrases related to your business.
Get keyword ideas
Your ads appear on Google
When people search on Google using one of your keywords, your ad may appear next to the search results. Now you're advertising to an audience that's already interested in you.
You attract customers
People can simply click your ad to make a purchase or learn more about you. It's that easy!
They provide the best tools, you can target your customers, by asking google to just publish your ads for the seraches done from aparticular area. If you want to advertise your local business then that's the best option available.
And you choose how much money you want to give in a day and per click (it can be anywhere from $1 to $10000000.... )
How can I earn money from these advertisements.
Now you can earn a share of the revenue that Google earns from Adwords by placing these same text ads on your site. In other words, you're helping Google advertise and they pay you a percentage of what they earn.
This program is called AdSense.
Every website owner should be involved in this. It's just too good of an opportunity to pass up. Even if your site is just for information purposes, you can still participate and make decent money with AdSense -- or at least enough to fund your website.
So if you are one of those people that don't like the idea of paying for a site, this is an excellent way to earn your money back and then some.
Even if you earned as little as $10 in a month, it would more than likely cover some or all of the costs for your web site. Perhaps you are simply looking for ways to add additional revenue to your website, then it's perfect for that situation too.
This program is getting so popular, people are creating websites just to display the ads and profit from Google's AdSense alone.
I don't usually like to use the term "easy money" because there really is no such thing. You still have to create your own website and learn how to bring in traffic in order to make good money with this program.
I certainly don't want to make it sound like you get something for doing absolutely nothing. There's no such thing.
However, I've got to say that AdSense is probably the closest you'll ever come to fast money on the Internet -- especially if you already have a website that gets a good amount of traffic.
What's even better...the program is completely free. You can also use it on multiple websites and there is no limit to the amount you can earn.
How AdSense Works
If you go to Google.com and do a search for almost any keyword phrase, you'll notice some "Sponsored Links" that appear on the right side of the screen that are relevant to the keywords you just searched for.
Website owners pay Google to display these ads and are charged a predetermined amount every time their ad gets clicked by a web surfer. With the AdSense program, you will display these same text ads on your site just like Google and get paid for it as well.
All you do is copy and paste some provided HTML code into your pages and Voila! the ads will show up. Every time an ad is clicked on your site, you will receive a certain percentage of what Google receives from the advertiser.
Once your account reaches $100, you'll receive a check in the mail. They send a check where ever you are in this WORLD.
"Is Google Crazy?"
I know what you're probably thinking...
"What's the catch here? Why would Google just give away money advertisers are paying them?"
The answer...
Because Google is very smart.
Now that I understand how AdSense works, I can see that it's a win-win situation for everyone involved, and the bottom line benefits Google. Let me explain...
Since the advertiser's ads are now being displayed on more web sites all over the internet (instead of just Google's site), they are getting much more exposure. More exposure means more clicks and even more traffic for their site over a shorter period of time.
This is good news for Google because the more traffic the advertisers receive, the faster their advertising funds are used up.
Remember, they get charged every time their site gets a visit; and of course, it is Google's hope that they'll continue to keep funneling more money into their account for more ad exposure.
What an ingenious way for Google to increase the amount of money they earn from advertisers while building loyalty with website owners (like us) who are now getting paid to help them advertise.
Of course, I'd expect nothing less from the most popular search engine on the web. :)

Divide to rule? Interesting piece ...
From Dr Dobb's Portal (CMP)
Embrace, Extend, Exterminate?
Over at ciol.com, Shashwat Chaturvedi has written a long and insightful backgrounder and analysis of the Microsoft/Novell pact, and what it means for global open source, and for the prospects of
open source in India.
Chaturvedi is a good thinker who knows his history and reasons well from premises. And he's interviewed some of the inheritors of Raymond Noorda's mantle, here, who add significant insight. Worth a read http://www.ciol.com/content/developer/dotNet/2006/106112101.asp
The Nokia 888 communicator changes shape on demand
Nokia recently unveiled a new concept phone (the Nokia 888) that changes shape on demand. The product took home first place in Nokia's Benelux design contest, thanks to a number of innovative features - such as liquid batteries, a flexible touch screen, and speech recognition - that make traditional mobile phone keys obsolete. The product even has a great tagline - "Perfect form does not exist... Form follows you." The Nokia 888 has the ability to transform how people think about mobile communication devices:
"A personal mobile communication device which lets you be free and fun. It is light, simple and carefree. You can change its form according to your needs during the day. You don't have to carry it in your pocket or on your wrist. You can carry it anywhere, in any form. You can roll it, bend it, put on your clothes like a clip. It also makes some form changes that makes it more ergonomical, i.e. when you want to talk on the phone, the body form turns into the form of the good old telephone. You can personalize these forms and record them. So it fits you the best in the way that you have chosen. Also e-motions let you send forms to other 888 users: i.e. you can send a heart shape to your girlfriend or a dancing figure to your friends to call them to the party tonight. This way you can talk without words."
The phone was designed by Tamer Nakisci for Nokia. Anyway, check out the comments on the Yanko Design site - people are calling the new phone "mind blowing," freaky," "really unbelievable" and "amazing." And, of course, there are the naysayers, who claim the phone is a "fake" (perhaps because a really annoying and really intrusive 888.com poker & casino advertisement pops up whenever you try to find out more about the Nokia 888 phone). It looks like there is a ready market for the phone if Nokia is able to move it from concept to mass-market commercial product.

Jog Falls India
Video Length: 38 secs
Video Length: 4 secs
Jog Falls, view from the bridge
Video Length: 1 min 20 secs
The water falls is about 100mts from here... if you observe carefully, you will see that the flow kinda ends... that's where the falls are...
Video of Jog Falls in late monsoon
This is another tall waterfall that runs amok during monsoon season, exceeding even Kaieteur Falls in Guyana in terms of height and volume. This video was taken during Monsoon..
River Sharavathi splits up into four different tracks which are named in accordance with their perceived trajectories. Going from left to right respectively in the picture, the names and the reasons for naming are:
* Raja (King): Named so because of its apparently 'dignified' and 'serene' fall.
* Roarer: This stream appears out of a mass of rocks, making a tremendous amount of noise.
* Rocket: Consists of a large volume of water streaming out of a small opening at a very high speed.
* Rani (Queen), also called Lady: The stream has a winding, twisting trajectory, said to resemble the movements of a female dancer.
