proven that the collision between two or more small quasicrystals results in the formation of a crystal which no longer possesses the grain boundary or the consequent imperfections. This process was virtually recreated in a lab multiple times in order to obtain the precise conditions necessary for the combining of these quasicrystals. (6) With our knowledge of quasicrystals

increasingly growing, it is possible that quasicrystalline products will become more abundant and it may even become easier to find new types of them forming naturally beyond the walls of the labs. -Erin

Theories of Light and Radiation that led to the Growth of Quantum Physics Quantum Physics is arguably one of the most ground-breaking branches of physics today. It has shown us a whole new side to the scientific realm: the absurd rules that govern the very tiny. Quantum physics plays a part in much of everyday life, for instance helping our mobile phones to work, by helping to design the siliconebased elements of our phone circuits. Many concepts that are known today in quantum physics actually grew from discoveries about light and radiation made by physicists in the 18 and 19 hundreds. So, in this article I wanted to enlighten you about some of these discoveries and how they led to the growth of this theory.

Christiaan Huygens believed that light was a wave, comparing it to the way that pebbles caused ripples in water. At first, Huygens and his theory about waves was not shared by most at the time. However, later, a scientist named Young was able to prove that light was a wave. He used the double slit experiment to show that light did follow the pattern of the wave, as when light was filtered through a single slit and a double slit, it spread out in circles, behaving exactly as a wave should. However, we now know that light is actually a particle and a wave, depending on whether it is being observed or not. Now these reflections on light were furthered by Gustav Kirchhoff’s discovery of blackbody radiation. This was essentially the spectrum of radiation emitted from a ‘blackbody’ or perfect emitter when it is heated. There is very little radiation emitted at short wavelengths, and long wavelengths, while a lot of radiation is emitted at middle wavelengths. This seemed confusing at the time, because it went against the classical

One of the first things that led to growth of quantum physics, was questions about the nature of light. This began with the renowned Isaac Newton, who had some very interesting ideas about particles. He held the belief that light was made up of many small particles called corpuscles. However, this belief was not held by some other scientists of the time. A Dutch scientist named 32
