Higgs Boson Discovery: Why It's Important to All of Us
NEWS ANALYSIS: Even though there are no apparent practical applications for the discovery of the elusive Higgs Boson, a subatomic particle that gives mass to everything else in the universe, there is no telling what role it may play in the future. It will certainly expand our understanding of how the universe took shape.
Its impossible to overstate the importance of the Higgs Boson, the discovery of which was announced at CERN (Conseil EuropÃ©en pour la Recherche NuclÃ©aire). Without this particle, you wouldnt exist. For that matter, the universe wouldnt exist. Thats because the Higgs Boson creates a field that gives other particles mass, giving weight and shape to all the matter we see in the universe
Or, to describe the indescribable, what the Higgs Boson does is create a field of virtual particles that pop in and out of existence, and while theyre in existence those virtual particles provide mass to other particles that are able to interact with them. Photons, which are being created by the bazillion (to use the precise scientific term) by the monitor in front of you, are the particle manifestation of the electro-magnetic field we call light. Photons are very real and depending on how theyre observed can appear as either particles or waves.
Photons have little mass, so little in fact that it takes something as massive as a star (or a former star in the form of a black hole) to affect them. In the rest of the universe, the photon can be considered massless. Another particle with which youre familiar is the electron, which does have mass, although not a lot.
I mention the electron, because it illustrates why you may want to pay attention to the Higgs Boson. The electron was discovered in 1897, but while it was understood to play a role in electricity and in electrical transmission, the use of the electron itself didnt really happen until the development of electronics. And some of the electrons more interesting capabilities werent understood until much more recently.
For example, a major cause of power loss in electronic devices is due to a characteristic called electron tunneling. Because an observer cant know precisely where an electron is physically located, its position is a statistical probability. But the electron doesnt care where it probably is. The electron can be anywhere in a range of 1 to 3 nanometers. This means it can pass through a barrier or it can appear on an adjacent wire in an integrated circuit.
But engineers can make use of this characteristic to create devices such as tunnel diodes. These are devices that have a number of useful characteristics, but the bottom line is that they are widely used in frequency converters and detectors.
