them. This is what led me to the book 'Reality Is Not What It Seems: The Journey to Quantum Gravity'. It helped me glimpse into the world of physics, from Greek philosophers like Democritus, past Newton and calculus, to a future of quantum gravity and more. Matvei Bronstein has a short, sad but important part of this. this. His story got me interested in the unification problem as the first person to show that quantum gravity affects space-time, causing me to develop a curiosity about theoretical physics

John Dalton was born in 1766 in England. At the age of 14 years old, Dalton became a teacher and taught at a Quaker school in his village, where he attended until eleven years old. “Dalton continued teaching himself science, mathematics, Latin, Greek and French.” At the age of 26, he taught mathematics and natural philosophy at Manchester’s New College. In 1794, he wrote his first scientific paper about color blindness. Although it was later proven wrong, he was the first to research about it. He

do, you most likely saw it in a science book, at a section about atoms. What most people don’t know is that he did a lot more. As you read, you’ll learn more about the clever, Niels Bohr. In Copenhagen, Denmark, October 7th, 1885, the father of quantum mechanics was born. His parents named him Niels. He was the second child of three children, in a prosperous, upper-class family. His father was Christian Bohr a brilliant physiology professor and his mother was Ellen Adler, daughter of a wealthy politician

Today, our speaker is a great mathematician who has made many contributions to the field of mathematics, especially regarding geometry, trigonometry, and calculus. Through his lifetime, he has been a revered published author and has many prolific articles depicting his research. The man I am referring to is the eighteenth mathematician, Leonhard Euler. At a young age, Euler showed a propensity to mathematics and that was recognized by many elder mathematician. As a teen, Euler was discovered by

The field of business contains various paths that are interconnected through communication. Marketing, more specifically, is a field that would be nothing without communication. At its very heart, marketing is the communication between a business to its existing and potential customers. What I have been told in my classes is that the field of marketing is ever-changing. Although base principles stay the same, people’s purchasing habits are constantly shifting along with culture and society. The communication

Without light, life on Earth would not exist. It is the most essential component in all of the universe and it is very complex. In 1799, Thomas Young began to study sight and the behavior of light, otherwise known as optics. During his time, Young made many scientific advancements in the field of optics that have impacted the world we know today. This report will be discussing the topic of Thomas Young's Double-Slit Experiment. Take note of the diagrams as presented in paragraphs one and three

Chapter 1: Asterisms vs Constellations One of the things that I found interesting in chapter one was the difference between asterisms and constellations. Growing up, there was an impression that a constellation was the pattern that the stars made at night to create a picture. But that’s not what a constellation is according to author’s Timothy Slater and Roger Freedman. They define a constellation as semi-rectangular regions that divide the night sky. (Slater) So then what are those patterns in

We use time to regulate our daily lives. We look at our watches, moreover, our phones now to deduce our actions timely. Well, those clocks on phones are controlled by the atomic clock administered by the National Institute Standards and Technology, NIST. Before mechanical clocks were invented, using “celestial bodies and sundials” were the accepted forms of timekeeping (Catwright). After the suggestion of a possible creation of a clock by physicist Isidor Rabi using his “resonance method for recording

The question of being is the darkest in all philosophy.” So concluded William James in thinking about that most basic of riddles: how did something come from nothing? The question infuriates, James realized, because it demands an explanation while denying the very possibility of explanation. “From nothing to being there is no logical bridge,” he wrote. In science, explanations are built of cause and effect. But if nothing is truly nothing, it lacks the power to cause. It’s not simply that we can’t

In this work, we consider two kinds of a spherically symmetric semiconductor quantum dots: (a) type I single quantum dot (SQD) with radius r_1, in which electrons and holes are confined in the same region of space, and (b) type II core/shell quantum dot (CCQD) with the same core radius, r_1, coated with shell thickness t=r_2-r_1, in which the spatial confinement of electrons and holes depends strongly on the geometrical parameters (core radius and shell thickness) and strain effects. Due to the potential
