MSI GX660 - Speedy Gaming Laptop

Hi guys if you are bored of Dell, HP laptops and you dont want to spend 2000$+ Alienware laptops but still wanting the top performance for the price, then here is the answer. MSI GX660. MSI, a renowned brand for motherboards and graphics cards  all over the world has recently entered the mobile computing market with a bang, their GX640 was a huge hit. Having the performance of a 1700$ alienware (similar specs), GX640 was hard to beat. But it had some disadvantages, including keyboard flex, grainy screen, and the CCFL backlit display (modern laptops use LED backlit displays).

So here comes the GX660 with a thumping config which is again hard to beat. For 1300$, you get the performance of a 2000$ alienware.

Time Travel not a science fiction anymore!!!!!!!!!!!!!!!! -Part 2

HOW TIME TRAVEL WORKS

hi guys this is the contiunation of my previous post. If you are reading this, am sure that Stephen has convinced you that time travel is possible. Som how do we practically do it???? Hawking explains...


The keys to time travel are black holes, objects so dense that not even light can escape their gravitational grip.
A black hole has a dramatic effect on time, slowing it down far more than anything else in the galaxy. That makes it a natural time machine.

Here's how it might work:

Imagine a spaceship orbiting the super-massive black hole at the center of the Milky Way galaxy, 26,000 light years away. From Earth, it would look like the ship is making one orbit every 16 minutes. But for the brave people on board, close to this massive object, time would be slowed down. For every 16-minute orbit, they'd only experience eight minutes of time.If they circled for five years, local time, 10 years would have passed back on Earth.

This scenario doesn't produce the paradoxes inherent in wormhole travel, but it's still pretty impractical.

But there's one more possibility: traveling super fast. 

This is due to another strange fact about the universe -- the cosmic speed limit: 186,000 miles per second, or the speed of light. Nothing can exceed that speed. It's one of the best established principles in science but believe it or not, traveling at near the speed of light transports you to the future.

Imagine a track that goes right around Earth, a track for a super-fast train. Onboard are passengers with a one-way ticket to the future. The train begins to accelerate, faster and faster. Soon it's circling the Earth over and over again. To approach the speed of light means circling the Earth seven times a second. But no matter how much power the train has, it can never quite reach the speed of light, since the laws of physics forbid it.
Instead, let's say it gets close. Something extraordinary happens: Time starts flowing slowly on board relative to the rest of the world, just like near the black hole, only more so. Everything on the train is in slow motion.

Speed of Light Protection

This happens to protect the cosmic speed limit. Here's why:

Say there's a child running forward up the train. Her forward speed is added to the speed of the train, so couldn't she break the speed limit simply by accident? The answer is no. The laws of nature prevent the possibility by slowing down time onboard. Now she can't run fast enough to break the limit. Time will always slow down just enough to protect the speed limit.

This is the essence of why time travel into the future is possible.

Imagine that the train left the station on January 1, 2050. It circles Earth over and over again for 100 years before finally coming to a halt on New Year's Day, 2150. The passengers will have only lived one week because time is slowed down that much inside the train. When they got out they'd find a very different world from the one they'd left. In one week they'd have travelled 100 years into the future.

Right now, the fastest motion on Earth is taking place in the circular tunnels of the world's largest particle accelerator at CERN, in Geneva.

When the power is turned on (particles) accelerate from zero to 60,000 mph in a fraction of a second. Increase the power and the particles go faster and faster, until they're whizzing around the tunnel 11,000 times a second, which is almost the speed of light. But just like the train, they never quite reach that ultimate speed. They can only get to 99.99 per cent of the limit. When that happens, they too start to travel in time. We know this because of some extremely short-lived particles, called pimesons. Ordinarily, they disintegrate after just 25 billionths of a second. But when they are accelerated to near-light speed they last 30 times longer.
To accelerate humans to that speed, we'll need to be in space, noting that so far, the fastest that people have traveled is 25,000 mph aboard Apollo 10.

To travel in time we'll have to go more than 2,000 times faster (than Apollo 10).  And to do that we'd need a much bigger ship, a truly enormous machinebig enough to carry a huge amount of fuel, enough to accelerate it to nearly the speed of light. Getting to just beneath the cosmic speed limit would require six whole years at full power.

We could, in theory, travel extraordinary distances within one lifetime. A trip to the edge of the galaxy would take just 80 years.

Time Travel is not a science fiction anymore!!!!!!!!!!!!!!!! -Part 1

Hi guys, I was absolutely spellbound watching this program in Discovery channel and thought of sharing with you. So let us "GO INTO THE UNIVERSE" with Stephen Hawking who  in the year 2009 was awarded the Presidential Medal of Freedom, the highest civilian award in the United States. 

I had a lot of doubts while watching the documentary and so did a bit of research online so that i can explain it clearly. (hope so :-) )

I will make this post as a personal interview with Stephen Hawking (;-0)

Me        : hello sir, we are baffled seeing the topic.. Is time travel possible?

Stephen : Yes. First, though, you have to get your head around the notion that time is a dimension, just like width, height and length. You are driving a car: You go forward. That's one direction. You turn left or right, that's a second. You journey up a mountain road, that's a third. The fourth dimension is time.

Me        : Enlighten us. 

Stephen : The laws of physics actually accommodate the notion of time travel, through portals known as wormholes.The truth is wormholes are all around us, only they're too small to see. They occur in nooks and crannies in space and time. Nothing is flat or solid. If you look closely enough at anything you'll find holes and wrinkles in it. It's a basic physical principle, and it even applies to time. Even something as smooth as a pool ball has tiny crevices, wrinkles and voids. Down at the smallest of scales, smaller even than molecules, smaller than atoms, we get to a place called the quantum foam. This is where wormholes exist. Tiny tunnels or shortcuts through space and time constantly form, disappear, and reform within this quantum world. And they actually link two separate places and two different times.The tunnels, unfortunately, are far too small for people to pass through -- just a billion-trillion-trillionths of a centimeter -- but physicists believe it may be possible to catch a wormhole and make it big enough for people, or spaceships, to enter.

Me         : That sounds complex. If i could travel in the past and do something that prevents myself from being born, how could I exist in the future to travel back in time?

Stephen : Exactly. We call this as the Time Travel paradox ( Grandfather paradox). Ultimately, scientists may find that only travel into the future is possible, as the laws of nature may make travel to the past impossible so the relationship between cause and effect is maintained.

Me         : We had always thought time is like a river which has an unidirectional flow???

Stephen : Indeed.. Time flows like a river and it seems as if each of us is carried relentlessly along by time's current. But time is like a river in another way. It flows at different speeds in different places and that is the key to traveling into the future. Albert Einstein first proposed this idea 100 years ago that there should be places where time slows down, and others where time speeds up. He was absolutely right.

Me          : We really appreciate the concept. It would be better if  we have a proof..

Stephen :  The proof lies in the Global Positioning System satellite network, which in addition to helping us navigate on Earth, reveals that time runs faster in space. Inside each spacecraft is a very precise clock. But despite being so accurate, they all gain around a third of a billionth of a second every day. The system has to correct for the drift, otherwise that tiny difference would upset the whole system, causing every GPS device on Earth to go out by about six miles a day. The clocks aren't faulty -- it's the pull of Earth that's to blame.

Einstein realized that matter drags on time and slows it down like the slow part of a river. The heavier the object, the more it drags on time, and this startling reality is what opens the door to the possibility of time travel to the future."

Me       : ????????????!!!!!!!!!!!!!!!!

What if the past giants of science had Twitter?

I personally love Steve Mirsky's way of explaining things. This is one of his best. Enjoy..


Have you joined the twitterverse? All over the world millions of people are posting their 140-or- fewercharacter tweets online via Twitter. As a confirmed Twitterer, I wondered what it might have
been like if Twitter, and all its users, had been around for, oh, the past few thousand years.

PythyinGreece Had amazing insight into right triangles.
Add squares of sides = square of hypo. Could be useful.

by dividing into smaller and smaller sections until width
of each disappears, call it calculus.

AppleNewt @Libnits You made that up? You couldn’t make

sounds disgusting.

Libnits @AppleNewt Keep sitting under trees, maybe something
big will fall on you next time.

AppleNewt @Libnits Apple falls near you, best idea you have
is “Ooh, let’s make applesauce.”

HairyAlbert @AppleNewt Pick on somebody your own size.
Btw, your gravity’s wrong. Just a teeny bit most of the time,
but hey. @Euclidmenot You too.

Memory capacity of the Human Brain - Revealed

Well..... have you wondered how much our brain can store??

Paul Reber, professor of Psychology at Northwestern University, replies: “Mr. osborne, may I be excused? My brain is full,” a student with a particularly tiny head asks his classroom teacher in a classic FarSide comic by Gary Larson. The deadpan answer to this question would be, “No, your brain is almost certainly not full.” Although there must be a physical limit to how many memories we can store, it is extremely large. We don’t have to worry about running out of space in our lifetime. The human brain consists of about one billion neurons. Each neuron forms about 1,000 connections to other neurons, amounting to more than a trillion connections. If each neuron could only help store a single memory, running out of space would be a problem. You might have only a few gigabytes of storage space, similar to the space in an iPod or a USB flash drive. Yet neurons combine so that each one helps with many memories at a time, exponentially increasing the brain’s memory storage capacity to something closer to around 2.5 petabytes (or a million gigabytes).
For comparison, if your brain worked like a digital video recorder in a television, 2.5 petabytes would be enough to hold three million hours of TV shows. You would have to leave the TV running continuously for more than 300 years to use up all that storage. The brain’s exact storage capacity for memories is difficult to calculate. First, we do not know how to measure the size of a memory. Second, certain memories involve more details and thus take up more space; other memories are forgotten and thus free up space. Additionally, some information is just not worth remembering in the first place. This is good news because our brain can keep up as we seek new experiences over our lifetime. If the human life span were significantly extended, could we fill our brains? I’m not sure. Ask me again in 100 years.
