Anyone have some good suggestions for books on Astronomy?

Posted: 25 May 2011 12:00 PM PDT

I am planning on indulging into the subject of Astronomy and Astrophysics. I am looking for a book that covers the specific sciences of the universe in detail. One that explains it well and is informative with many facts. Thanks. :)

Could graphene replace silicon?

Posted: 25 May 2011 11:07 AM PDT

Scientists at the University of South Florida (USF) have created an anomaly that could allow graphene to eventually replace silicon as the primary material in electronic devices.

Indeed, previous attempts at creating anomalies proved inconsistent and produced samples in which only the edges of thin strips of graphene or graphene nanoribbons contained a useful defect structure.



However, the USF team developed a method of producing a well-defined, extended defect several atoms across which contains octagonal and pentagonal carbon rings embedded in a perfect graphene sheet.

According to PhysOrg, the defect functions as a quasi, one-dimensional metallic wire that conducts electric current and can be used as metallic interconnects or elements of device structures of all-carbon, atomic-scale electronics.

To create the anomaly, the team used the self-organizing properties of a single-crystal nickel substrate, along with a metallic surface as a scaffold to synthesize two graphene half-sheets.

When the two halves merged, they naturally formed an extended line defect with a well-defined, periodic atomic structure and metallic properties within the narrow strip along the defect.

"This tiny wire could have a big impact on the future of computer chips and the myriad of devices that use them. In the late 20th century, computer engineers described a phenomenon called Moore's Law, which holds that the number of transistors that can be affordably built into a computer processor doubles roughly every two years," explained PhysOrg.

"This law has proven correct and society has been reaping the benefits as computers become faster, smaller and cheaper. In recent years, however, some physicists and engineers have come to believe that without new breakthroughs in new materials, we may soon reach the end of Moore's Law. [But] Metallic wires in graphene may help to sustain the rate of microprocessor technology predicted by Moore's Law well into the future."

Hello Friends,

I am a new comer to this forum. go easy on me... :)

Name: Mohamed Haroon
Engineering Trade: Mechanical / Manufacturing
Location: Chennai, India

Occupation: Working as a Manufacturing engineer at a private automotive component manufacturing firm..

Work Experience: almost 2 years.
I have hands on knowledge in CNC FANUC programming and cutting tool technologies. I am currently learning FANUC Robotics.

I have a grounded understanding and experience in implementing total quality management practices in the manufacturing field. Stuff like TPM, kaizens, Troubleshooting using tools like Fish-Bone, Paretos etc etc.

I am also a Six sigma green Belt.

Hobbies & Interests: Automobile technology is an exciting field, very enthusiastic about sports cars and watching races, fond of ferraris, recently fell in love with the top gear magazine and the tv show by the same name.

*I joined CrazyEngineers because:

i was searching for an explanation on CRDI technology and thats how i stumbled here...

this seems a great place for like minded people..
im here to learn as well as share. im a friendly and down to earth guy.

nice to meet you all...
have a nice day.

Dell XPS 15z 15-inch PC - Is it the Cheapest Among The Thin Laptop Series?

Posted: 25 May 2011 05:02 AM PDT

Introduction Video:



Basic Features of Dell XPS 15z 15-inch PC:

2nd-generation Intel® Core™ i5 and Core i7 processors
15.6" Full HD (1080p) display
8 hours of battery life

Dell has claimed that it is the thinnest laptop on the planet. But worldwide reviews has mentioned that it's thicker than MacBook Pro. So, it definitely not the thinnest in the world.
Moreover, it weighs about 5.54 pounds which is same as other laptops in the thin range.

The base model is priced at $999. Does this mean it is the cheapest among other laptops?

What do you say?

A gold Vending ATM!!

Posted: 25 May 2011 04:53 AM PDT

Recently a Hotel in Abu Dhabi by the name "Emirates palace" installed a new Gold vending ATM machine,i.e, it can provide gold coins and gold bars too..:o
The company which makes them is "Ex Oriente Lux AG". Emirates palace is the second place where such a machine has been installed..
Can we think of any other purpose for which an ATM machine should be made ??:)

Robotic Adhesion With Supersonic Air Jets - University of Canterbury Researchers

Posted: 25 May 2011 04:41 AM PDT

A research group from the University of Canterbury in New Zealand has developed a supersonic version of the Bernoulli gripper that's five times stronger than the conventional version, which is enough to allow a robot to climb on a bunch of different surfaces.

Moreover, note that grippers on this robot aren't touching the wall:

Aquapod Robot - Ambhibious Tumbling Robot By University of Minnesota

Posted: 25 May 2011 04:37 AM PDT

Aquapod is created by the University of Minnesota's Center for Distributed Robotics. It uses two carbon fiber arms connected to servo motors that can rotate continuously to, as the researchers put it, "induce a tumble." The reason that it's called Aquapod, incidentally, is that it's also waterproof, with the ability to control its buoyancy, floating or sinking or even just chilling out somewhere in the water column.

This enables it to operate quite happily on land as well as in water, where it can sink itself to the bottom of lakes and streams and tumble along the bottom.

What's your take on this robot?

No. of electrons

Posted: 25 May 2011 04:17 AM PDT

is any one tell me that how many electrons pass through a point when we say that 1 coulumb charge pass through that point.

Any 3DTVs without issues

Posted: 25 May 2011 03:30 AM PDT

Hi to all,

I am planning to buy a 3DTV for myself after watching it at one of my friends place.

Although i liked the experience,the issues like dizziness,headaches is making me think twice before buying one.

Any suggestions regarding the same would be appreciated.
