Robot Building? Which set is the best?

LEGO Mindstorms NXT is the correct choice if you are new to robot building and want to create amazing robots very fast which do almost everything possible including walking, running, seeing (yes, thanks to ultrasonic sensor) giving feedback to sounds, voices, touch, light and more.

There is a common scenario for many hobby starters. They are afraid to try such hi-tech hobbies because of the prejudice that it is so hard to build robots and program them.

First of all, LEGO Mindstorms NXT doesn't require any prior programming language and doesn't enforce you to learn. All you need to do is drag&drop. In later stages, you can surely continue with the programming tools which is provided in the system. You can transfer your program to robot's brain (NXT Intelligent Brick) through USB or Bluetooth wirelessly. So, you can control your robot in any bluetooth powered device including PDAs, laptops or even mobile phones.

What you get :
• 3 interactive servo motors feature inbuilt rotation sensors to align speed for precise control
• New ultrasonic sensor makes robots "“see" by responding to movement
• New sound sensor enables robots to react to sound commands, including sound pattern and tone recognition
• Improved light sensor detects different colors and light intensity
• Improved touch sensor reacts to touch or release and allows robots to feel
• 519 hand-selected, stylized elements from the Lego Technic building system ensure robot creations will be sturdy and durable while also looking authentic
• Opportunities for physical programming of robots and interaction with robots during programming
• 18 building challenges with clear, step-by-step instructions help acclimate users to the new system to create robots ranging from humanoids and machinery to animals and vehicles
• Digital wire interface allows for third-party developments
LEGO Mindstorms NXT is available on Amazon store with special promotions and free discounts.

Creativity is the key to happiness in this life!

The Nightmare of Stephen Hawking !

Scientific Cat-fight ! These were the first words when I have seen the cover of this cool science book on the first sight, The Black Hole War: My Battle with Stephen Hawking to Make the World Safe for Quantum Mechanics which is authored by Leonard Susskind, Felix Bloch Professor in theoretical physics at Stanford University.
What happens when something is sucked into a black hole? Does it disappear? Three decades ago, a young physicist named Stephen Hawking claimed it did-and in doing so put at risk everything we know about physics and the fundamental laws of the universe. Most scientists didn't recognize the import of Hawking's claims, but Leonard Susskind and Gerard t'Hooft realized the threat, and responded with a counterattack that changed the course of physics. THE BLACK HOLE WAR is the thrilling story of their united effort to reconcile Hawking's revolutionary theories of black holes with their own sense of reality-effort that would eventually result in Hawking admitting he was wrong, paying up, and Susskind and t'Hooft realizing that our world is a hologram projected from the outer boundaries of space.
It is one the most entertaining popular science books which is also brilliant and mind opening on the subjects like quantum mechanics, black holes, string theory, general relativity. Recommended for brain fun !

Trillions of Planets with Alien Life

Well, actually it is a long debate that there could be many earth-like planets where other alien life forms can exist. Actually Drake Equation was trying to formulate this mind blasting question for around 50 years. Now, a leading Cambridge Institution astronomer Alan Boss states that the number of earth-like planets could be at least 100 hundred billion trillion which results in an unavoidable fact for extraterrestrial life according to him. He also added that if there is an habitable planet, it would certainly appear some kind of life form there by time, in a few billion years. He believes that we will find such planets with the proven fact of simple life forms. How about the intelligent life besides bacteria? Well, according to him, it would be a big coincidence to find such creatures at the same time of ours because we will survive further 100,000 years further, very unlikely !
