A large portion of the book Alice in Quantumland tries to help Alice make sense of wave interference. The Classical Mechanic leads Alice to a place referred to as the gedanken room, meaning the thinking room. In said room, anything that one thinks appears as substance, making it possible to perform quantum experiments. The Classical Mechanical then proceeds to explain interference by a simple definition to Alice. “Interference is something that happens with waves. You can have all kinds of waves…

Mathematicians have been around for centuries. They have contributed great amounts of knowledge to the world. A mathematician is a person who excels or is an expert in mathematics. One specific mathematician that brought great ideas into the world was Gottfried Leibniz. He contributed a lot to mathematics, science, physics, philosophy and even his local government. Mathematicians are very important because without them we would not have many important theories that explain why certain things…

Biomechanics is the study of the body as a machine. This study of the body looks at the internal and external forces that act on the body and the movements that these forces produce. By grasping biomechanical concepts, it enables us to programme our bodies to correct technical errors, reduce injury, move our body with precision and understand the importance of equipment design. This can be used in all sports including volleyball. I will be analysing myself and how I compare to a professional…

Georg Friedrich Bernhard Riemann was born in Breselenz, a village close to Dannenberg in the Kingdom of Hanover, which is now mostly known as Federal Republic of Germany. His father, Friedrich Bernhard Riemann, was a poor Lutheran Minister in Breselenz who took part in the Napoleonic Wars and finally settled as a pastor in Quickborn. On the other hand, his mother, Charlotte Ebell, unfortunately died before her children had reached adulthood. Riemann was second among his 6 brothers and sisters,…

As many people may know, Isaac Newton was a man of many talents, but he was most famous for his law of gravitation. As a result, he played a significant role in the scientific revolution of the 17th century. Isaac Newton became one of the most influential scientists in that century. He invented reflecting lenses for telescopes which produced clearer images. During his life, he went through many hardships. He had a mental breakdown before losing his mother in 1678. Isaac Newton transformed the…

Newton’s Laws Sir Isaac Newton, the man who developed the first theories of gravitation, also introduced the three laws of motion. These laws essentially changed the field of physics in an astounding manner – it paved the way to modern science. Let’s look at these laws in some more detail: Newton’s first law: It states that an object will remain at rest or in a uniform motion, unless an external force acts on it. This is basically also the definition for inertia. In other words, the state of…

There are six fundamental movements or primary movements which occur where the joints are located between the body segments. These movements are flexion (frontal plane, and shoulder) extension, abduction, adduction, rotation, and circumduction. As explained in our text, flexion is a decrease in the angle between two body segments, whereas extension is an increase in the angle between two body segments. Abduction is a movement away from the body, whereas adduction is a movement toward the…

Physics plays an important role in the mechanics of a roller coaster. The thrilling ride cannot be appreciated, if the physics of a roller coaster is not understood. The loops, bends and hills are all affected by physics. The first hill of a roller coaster is the initial start of energy. Potential energy begins the transfer of energy on the first hill. A chain motor pulls the cars to the top of the hill creating potential energy. Potential energy being defined as the energy determined by its…

Dirt bike or motocross racing is an extremely competitive sport that has been enjoyed by masses of people across the globe. Millions of people have either watched or are very passionate about dirt bike racing. This is a sport that has been around for over one hundred years when the idea first came about in the U.K. motorcycle trial competitions in the early 1900’s ("Motocross"). As the sport grew in popularity, many improvements were made including: the terrain of the tracks, motorcycle…

Erwin Schrödinger, an Austrian born chemist, gained his famed for his contributions to quantum mechanics. Some of his contributions to chemistry and quantum mechanics were his books describing his techniques and basic info behind his work, his paradox, Schrodinger’s cat, which created a lot of new discoveries in chemistry, and his equation that changed how many people viewed the atom and its electrons. At at young age, Schrodinger was strongly influenced by the philosophy of Austrian philosopher…
