![]() ![]() Looking closely at the structure of transistors, we would realize that a transistor consists of layers of silicon associated with other elements. Transistors have widespread uses and are used to amplify or switch electrical signals and electrical power. You might be surprised to know the type of cryptochrome which is used for navigation by flies has also been found in the human eye! However, its use is unclear. Crustaceans, lizards, insects, and even some mammals make use of such type of magnetic compass. Another theory suggests that the beaks of the birds contain magnetic minerals. These radicals enable the bird to “see” a magnetic map. Photons, after entering the eyes of the bird, hit cryptochrome, and radicals are released. A light-sensitive protein called cryptochrome contains electrons. If you think that only the humankind has been lucky enough to make use of Quantum Physics, you are totally wrong! According to theories by scientists, birds like European Robin make use of Quantum Physics to migrate. How can the band structure be changed? Of course, Quantum Physics knows the answer! Once the band structure is changed, the conductivity alters as well. Not to forget that we are able to manipulate the electrical properties of silicon only because we can study the wave nature of electrons. Quantum Physics talks about the wave nature of electrons, and, so, this forms the basis of the band structure of solid objects on which semiconductor-based electronics are built. The whole computer world is based on the principle of Quantum Physics. So, the next time you switch on the lights of your room at night, make sure you thank Quantum Physics. Mercury has the ability to emit light in the visible range. In fluorescent lighting, a small amount of mercury vapour is excited into the plasma. The light which you are getting from the tubes or those curly bulbs is a result of a quantum phenomenon only. The rod in the toaster gets hot, which, in turn, is responsible for toasting the bread. Toasters are generally referred to as the reason why Quantum Physics came into existence. The heating element of the toaster glows red to toast a slice of bread. ![]() The bread toast which you enjoy while sipping on your morning tea is able to make its way to your plate only because of Quantum Physics. Here is a list of a number of things which depend upon Quantum Physics for their operation. Beginning with describing in the introduction a typical morning routine-waking up, making breakfast, checking his computer-Orzel breaks those actions down in order to “show how an ordinary weekday routine depends on some of the weirdest phenomena ever discovered.” For example, his alarm clock allows him to discuss, cogently, how the “modern accounting of time” that the device embodies is “deeply rooted in the quantum physics of atoms.” Orzel provides similar explanation for such phenomena as the different colors of light emitted by objects heated to different temperatures, using as an entry point the glowing coils of the burner on his stove top. It may surprise you to know that Quantum Mechanics is able to explain our senses of sight, touch and smell.Ī number of such examples are described by Chad Orzel in a book with a catchy title “ Breakfast with Einstein”. But once you get to know about the real-life applications of Quantum Physics, you might wonder that the examples of the same were right in front of you! If someone were to ask us the daily life or real-life examples of Quantum Physics, most of us would be totally unaware of it. The mention of the phrase ‘Quantum Physics’, immediately invokes a response of something quite weird and incomprehensible that happens in very special conditions in nature, and perhaps companies like Google, IBM and Microsoft are competing in a race to develop Quantum Computing, which will also be of use to a few specialist “ Quantum Physicists or Quantum Engineers”.
