Higgs boson and higgs field

Way back in 1964, Belgium's Francois Englert and England's Peter Higgs independently theorized the existence of subatomic particles that came to be known as Higgs Boson. Recently, on 4th July 2012, CERN (European Organization for Nuclear Research) announced that they have discovered a particle that exhibits similar properties as that of Higgs Boson.

Now let’s see what is Higgs Boson and Higgs Field. There are some subatomic particles which have mass whereas there are some whose mass is negligible. Peter Higgs proposed that the reason behind the mass of the subatomic particles was the Higgs Field. We can understand Higgs Field by comparing it with water. We know that aquatic animals have streamlined bodies which helps them to move through the water without much drag while we human beings find it comparatively difficult to swim through water as water proposes drag on our bodies. The same is with Higgs Field. Some subatomic particles interact less with the Higgs Field while others…

Chirp to share

Back in old days, if one had to transfer data between devices, it used to be difficult for mainly two reasons, one that it was wired and two that there were not many wireless protocols existing to transfer data between devices easily. Today numerous wireless data transmission techniques have made it possible to transfer data across devices easy. This though makes data transfer easier, it may lead to health problems as most of the existing wireless data transmission techniques use radio waves, microwaves or any other form of the electromagnetic spectrum. Health conscious people have contributed to the invention of safer and faster methods of data transfer. One such method of transmission is sound!

Use of audio to transfer data is not a new one. Animals and some insects use different sounds to communicate with each other. We are no different from them. We have been using sound for communication with others for a long time, though with lot of modification and complexity than animals. Toys…

10 Tips to Build Your First Robot

Robot building is a great activity to keep yourself and your brain engaged in something that is useful. Building a robot could be something like "impossible" for beginners but with proper organization, knowledge, guidance,tools and materials required it would become a cakewalk.

Here are some tips to help you in building your first robot.

NOTE: Robotics is very addictive. Once you get into it, it is very difficult  to come out of it. Dive into it at your own risk!

Tip #1: Start by learning about basic electronics and programming
This may seem boring but it is very important. Building a robot heavily involves the interplay of electronics,mechanics and software. On the electronics part a robot builder must have the knowledge  of atleast the basic electronic components like resistors, capacitors, transistors, LEDs, sensors... along with the knowledge of actuators, which form the mechanical part of the robot. On the software side one must know programming languages like C, Proces…
