Isn’t it too simple?” But think about it. No businessman produced novel products without trial and error. No great speaker can write a perfect speech in one night. Do you know what Newton said when he was asked how he successfully discovered the gravity? Do you think he answered, “By watching an apple falling from a tree by chance”? No. His real answer was, “By constantly thinking.” My simple message is don’t give up until the very moment of…
To facilitate an accurate description of the localized d and f electrons in the solids, the self interaction correction is introduced. Within the LSDA, the spurious self-interaction tends to underestimate their localization. In SIC-LDA formalism, the localized electrons see a potential (SIC potential) different from that of the delocalized ones for which the self-interaction vanishes and whose potential therefore reduces to that of the LSDA. It is known that self-interaction is important only…
Being known as “The Father of the Atomic Bomb” is a great accomplishment. To have this association as well as being known as “The Pope,” “The Prophet,” and “The Admiral” to his associates, an individual must be intelligent and have a background that allowed them to grow and prosper in physics (Latil 113). The man with this honor is Enrico Fermi and without him, who knows what would have happened in World War II. Enrico Fermi had multiple experiences and obstacles in his life, but all of the…
Pangea! It was the supercontinent that existed about 300 million years ago. According to Alfred Wegener’s theory, long before us humans existed all of the continents used to be one large landmass. Who is Alfred Wegener you might ask? Alfred Wegener was a German polar researcher, geophysicist, and meteorologist born in Berlin on November 1, 1880. I chose to research about Alfred Wegener’s life and his struggles because we are currently focusing on the continental drift theory in science class. He…
Introduction: Quantum physics, also known as quantum mechanics, is the branch of physics that uses quantum theory to predict and describe the properties of a physical system. While chemistry is the science of composition, properties, structures, and reactions of matter; it is also known as the ‘central science’. While reading the book Alice in Quantumland by Robert Gilmore, one is able to link the two together, causing a curiosity to learn more. It is amazing to see how the two correlate and…
schools but did not hold any type of formal degree. After college, Henry began following his father’s scientific footsteps. Being a follower of Newtonian philosophy and Newtonian mechanics, he began conducting experiments in gases, electricity and gravity. In 1766, Henry won the Royal Society’s Copley Medal for factitious airs with Hydrogen being the most notable of his discovery. Several years later, Cavendish quantitatively measured the mass of the earth and completed Newton’s law of…
Jeremy Hsu's article, “Scientists Create First Ever Trap for Rainbows” (2009), asserts that anyone can capture rainbows. Hsu makes this argument by explaining how scientists have manipulated lens and other materials, such as glass, varying in thickness, size, and optical coating, to capture a rainbow when a laser beam was shone through it. Hsu’s motive is to inform readers of this discovery, which involves a rainbow, an optical phenomenon that has amazed people for several generations, in order…
One of the most important scientific discoveries is that of the atom. The Atom is the smallest unit of matter. “Atoms are mostly empty space” (OI/ https://www.thoughtco.com/interesting-facts-about-atoms-603817). It makes up all the four elements. “There are over 100 different kinds of atoms ”(OI/https://www.thoughtco.com/interesting-facts-about-atoms-603817).Over time the theories about the atom have changed a lot, moving from simple to complex. Before 1900, scientists made several…
Asal Bahmani 12.20.16 Franey//Adams Chem P.6 Going back through history the experiments, discoveries, and works of past scientists such as Democritus, Dalton, Thomson, and Rutherford have afforded us the opportunity to draw from their ideas to formulate a modern view and accurate understanding of the atom. Thanks to the evolution of atomic models. In the beginning, Democritus viewed the atom as a tiny, solid, round sphere, that was unable to be cut. He created the first model of an atom, that…
“Steel plates are commonly attached to each other with rivets, which are slipped into holes in the plates and rounded over with hammers. The hotness of the rivets makes them easier to round over, but their hotness has another important advantage in providing a tight fit. What is it? Explain why.” This relates to one of the characteristics of heat, in that heated objects expand, then contract when the temperature decreases, since the molecules move faster in heat and slow in the cold. The hot…
