God Particle:
Why its a God particle: The Standard Model is to physics what the theory of evolution is to biology. Now the Higgs boson so called GOD Particle is the very base of this Standard Model theory. May its the importance of Higgs boson the scientists have namded it God Partricle. It describes 12 fundamental particles, governed by four basic forces. The other 11 particles predicted by the model have been found and finding the Higgs would validate the model.

Why is the Higgs so important: One of the great challenges of particle physics is to explain why the elementary particles of matter have the properties they do – in particular why different particles have different masses. According to the Standard Model, particles acquire mass as a result of their interaction with a certain type of quantum field, named the Higgs field. The Higgs field is a theoretical and invisible energy field that pervades the whole cosmos. Some particles, like the photons that make up light, are not affected by it and therefore have no mass. Others find it drags on them as porridge drags on a spoon.

WHAT IS THE LARGE HADRON COLLIDE: The Large Hadron Collider is the world’s biggest and most powerful particle accelerator, a 27-km (17-mile) looped pipe that sits in a tunnel 100 metres underground on the Swiss/French border. It cost 3 billion euros to build. Two beams of protons are fired in opposite directions around it before smashing into each other to create many millions of particle collisions every second in a recreation of the conditions a fraction of a second after the Big Bang, when the Higgs field is believed to have ‘switched on’.

The vast amount of data produced is examined by banks of computers. Of all the trillions of collisions, very few are just right for revealing the Higgs particle. That makes the hunt for the Higgs slow, and progress incremental.

Window 7 mobile…..with this the sleeping giant is back. Breaking all silence finally microsoft comes speaking. There are many features which shows that Microsoft has taken a radical approach to the phone.

Tiles:: The tile function of the screen replaces the icon displays seen on the iPhone and the Android with living breathing tiles. Just picking up the phone you can see what is going on in your world without opening any app. To add I may say that this is sometimes better than push notifications.

Hub Strategy:: The HUB concept works really well. You can have a music hub in the shape of the Zune app. But this app is not restricted to content I have uploaded to, or bought in Zune, but all the music content on my ‘phone. Take the hub strategy across to other content, like business documents and Office becomes the business hub. This strategy gives me the best of both worlds, I can use my preferred app or I can find it in the main hub. Smart.

Games::  So what so special. Consider full on XBOX action on your phone? The graphics look up to it and the game levels, credits and achievements will be recorded against your Live profile.

Though I feel that Window 7 from microsoft is still an amateur but then like all babies this will also grow. I hope this creates even stiffer competition in market

Gmail voice and video chat makes it easy to stay in touch with friends and family using your computer’s microphone and speakers. But until now, this required both people to be at their computers, signed into Gmail at the same time. Given that most of us don’t spend all day in front of our computers, we thought, wouldn’t it be nice if you could call people directly on their phones?

You can call any phone right from Gmail.
Calls to the U.S. and Canada will be free for at least the rest of the year and calls to other countries will be billed at our very low rates. We worked hard to make these rates really cheap (see comparison table) with calls to the U.K., France, Germany, China, Japan and many more countries for as little as $0.02 per minute.

Google is an industry giant, google makes millions, google is topping everywhere and what not.
Google does not sell anything, everything you use from them is free and top of that they seem to be very active in the open source community.

Hmmmm,, seems a huge contradiction. Well life is like that only and we all love contradictions, Isn’t it. Actually last week I was sitting with some of my relatives and all the techies of my family were sharing their thought on GOOGLE and its power. Suddenly out of no where a question came from a teen “How does google make money?” After some silence I broke the ice and tried to make that teen understand how google makes money. So here is all who have similar question marks on their minds:

Advertisement: Yes that’s how Google is making its money. Every time you do a search on Google, you’ve probably noticed that there is a section called Sponsored Links. Every time you click on one of those links, Google charge a certain amount of money to the website for the click. Also when you go on a website you’ll notice advertising from Google too. Same thing happens here, when you click, Google charge a certain amount of money to the website you clicked on and part of that money is given to the webmaster publishing the ads. This is called AdSense and is an enormous source of income for Google.

How much does Google charge for a click?
The price advertisers pay for a click depends on a lot of factors and this is where Google is playing smart. They use a sort of bidding system. When you want to advertise with Google, you select keywords you are targeting. Let’s say I own an online mobile store and I want to bring potential customers to my website. I’m going to bid on the keywords mobile and buy mobile online for example. The price I’m going to pay will depend if there is other companies bidding for that keyword. The more companies are fighting for a keyword, the more I’m going to pay for a single click to my website. The price can vary from 0.01$ to 100$ and more. You can imagine that for highly competitive keywords like finance and health it can cost quite a lot of money for a company to advertise with Google. This program of Google is called Adwords.

No production cost
The beauty of google business is that Google doesn’t sell any tangible product. They sell something that doesn’t really exist. They really sell traffic. It mostly comes down to this: They get paid for sending traffic to other websites. That’s why Google seems to be everywhere now: They have to show substantial growth to their stakeholders and to do that they have to drive more and more traffic to provide more and more advertisement.

Hope that clears out atleast some of the mysterious business of Google. Keep questioning, Keep knowing more……..

VGA/QVGA/SVGA

VGA (stands for Video Graphics Array) is a default video format for mobile phones (for example, the LG Renoir) but is also the standard for cameras as well. This format uses very little space on the card/disk, and is relatively poor quality, and has small screen space (640×480), so that you can record more video quickly and easily (only recommended for simple videos). Also, Windows uses a system called SVGA (Super Video Graphics Array), which, only can display in poor quality modes, and, is unable to support a big display (SVGA supports 800×600 up to 1680×1050). QVGA (stands for Quarter Video Graphics Array) is the same as VGA, but smaller (320×240)

Video capture
