Pauli Exclusion Principle
Wolfgang Ernst Pauli was an Austrian theoretical physicist famous for his work on the spin and quantum theory, and for the beneficial finding of the Pauli exclusion principle. Pauli was born on April 25th, 1900 and died on December 15th, 1958. He was a Foreign Member of the Royal Society of London and a member of the Swiss Physical Society, the American
Physical Society and the American Association for the Advancement of Science. Pauli helped to set in place the basis of the atomic theory. His suggestion of the hypothesis explaining the behavior of electrons in atoms first came out in 1925. Then in 1945, he was awarded the Nobel
Prize in Physics for his help and contribution to the atomic theory, through

Pauli solved a “vexing difficulty” by introducing a new quantum number,
which is a quantity that was later called spin, and that became part of the Pauli exclusion principle. The second contribution he made was on the quantum field theory. Quantum field theory is a combined element of quantum mechanics and subatomic scale, which is a particle that is smaller then an atom like a quark and describes the properties of molecules and atoms of electron, protons, and neutrons. Quantum mechanics deals with the behavior of matter and light on the atomic subatomic scale. These particles are known to interact with each other with electromagnetic radiation. An electromagnetic radiation is the flow of energy at the speed of light through free space. An example of this radiation would be through light or x-rays. The last contribution was Pauli’s discovery of the existence of the neutral particles, later known as neutrinos. It was used to preserve the conservation of energy in nuclear beta decay.
Pauli was born in Vienna, Austria. His father was the chemist and physician Wolfgang
Joseph Pauli and his mother was the writer Bertha Camilla Schutz. He also had a younger sister,
Hertha, who became an actress and author. Pauli’s godfather, Ernst Mach, from whom he got his middle name, was the famous Austrian physicist and psychologist who studied the action of bodies moving and developed a method
Even though he is classified serial killer and contract killer he differs from typical serial killers. Unlike your typical serial killer who targets victims with a specific profile and will only target victims with the same specific profile, Mr. Kuklinski did the opposite and his victims were chosen at random. For Kuklinski, killings were only considered business for him and way for him to make money. At no time did he commit murder purposely to seek some type of sexual arousal. Also, he did not kill because he suffered from any psychological dysfunction. Although someone of his kills did occur during the heat of passion, but for the majority of kills that he has accumulated were all hits. In the documentary called The Iceman Confession peers into the life of Richard "the Iceman" Kuklinski. In the HBO documentary on the Kuklinski, the assistant attorney general who prosecuted the
Linus Pauling was the greatest chemist of the twentieth century – arguably of all time. He was a theoretical physical chemist who became the only person to have won two unshared Nobel Prizes. Growing up in Oregon, Pauling taught himself the fundamentals of chemistry while he was still a teen. His work on chemical bonding marks him as one of the founders of modern quantum chemistry, and his discovery of the alpha helix and beta sheet is a major foundation for the study of protein structure. Although he is mostly known for his successes, he made one principal mistake, which affected his legacy.
Joy Harjo’s “Remember” seems at first to be a simple plea from an unidentified speaker that the listener (standing in for all people) “remember.” “Remember you are this universe and this / universe is you” (lines 21-22), says the speaker. Throughout the poem, the speaker tells the listener to remember sixteen times; “remember” is an anaphora, a repetitive command by the speaker that seems to indicate that “remembering” is what the poem is about. Look deeper, though, and the poem seems to be about the interconnectedness of all things, and understanding that people, nature (plants and animals), the earth and sky, and the universe are all connected and related to each other. Look even deeper, though, and the essence of the poem becomes obvious:
Principle”. The French team of Pierre and Marie Curie who are known as the parents of nuclear physics came to the realization that the atom has a core, or nucleus. It became apparent that different laws of physics govern the nucleus. In Cambridge England, Sir J.J. Thomson who in 1897 discovered the electron and his pupil Lord Ernest Rutherford discovered the proton. The history of the atomic age was coming right along on a steady pace then in 1905 Albert Einstein wrote the mass-energy conversion equation, and things started to progress very rapidly. In 1932 Sir James Chadwick discovered the neutron, this rovided an ideal projectile for splitting the atom. The final clue to the neutron and atomic energy was when an observation was noted that a peculiar property of the radiation emitted when beryllium is bombarded with alpha particles. In 1938 the discovery of fission of the uranium nucleus by neutron bombardment. In 1940 President Roosevelt organized the National Defense Research Committee, which was determined to develop an atomic bomb. Development and construction of the atomic bomb was the most closely guarded secret in scientific history. This was a
3) Atoms of a particular element are identical in mass, size, shape and other properties.
“You know now your own life doesn’t belong to you/ The way a child defects into his childhood” (11-12). That is an excerpt from the poem “Replica” from her book; quotes like these really showcase Ruefle’s writing style and is strong example of her many punching lines of poetry. Ruefle’s Selected Poems is a book of poetry that conveys a wild imagination, sensitivity, and melancholy humor. Ruefle who often used first person throughout the book could instantly grab the reader with her vivid images. Also, she connected on a relatable level with the audience by using first person in her poetry. Ruefle used her book to tell complex stories while using vivid imagery and descriptive language.
He discovered the electron and experimented by testing the electric discharge in a high vacuum cathode ray tube. (Nobel Lectures.1967)
Over the past millennia, our understanding of the atom has evolved through eager hypothesizing, numerous trials and startling discoveries. From the first atomic theories of the Democritus in Ancient Greece to the gold foil experiment that allowed Ernest Rutherford to discover the atomic nucleus in 1909, humanity has come far on the path to crack the mysteries of the atomic structure and the hidden secrets that lie within. However, it was only in the 1930s that the full basic structure of the atom was finally completed with the discovery of the neutrally charged particle known as the neutron.
Each sublevel has a different number of orbitals, S has one orbital, P has three orbitals, D has five orbitals, and F has seven orbitals. The arrangement of electrons is called electron configuration, electrons usually like to be in an arrangement that gives the atom the lowest possible energy, also know as it’s ground state. There are principles to determine how the electrons are arranged, the aufbau principle, pauli exclusion principle, and hund’s rule. The aufbau principle states that all orbitals related to a sublevel are of equal energy, the order of increasing energy of sublevels is s, p, d, and f, and the orbitals of one energy level can overlap with the orbitals of another energy level. The pauli exclusion principle states that in each orbital there can be a maximum of two electrons, but only if they are spinning in different directions, also arrows pointing up or down are used to show the spin of electrons.

Enrico Fermi is famous for building the first nuclear reactor. In 1938, he won a Nobel Prize for his major accomplishments in radioactivity. After he won the Nobel Prize, he left Italy, and traveled to the United States. Fermi had a very tough life. His interests in physics were discovered after the death of his brother. At age 14, Enrico came upon some physic books written a half a century before him. Later on, he claims to not even know the books were written entirely in Latin. These books were a big boost on Fermi’s physics career. In 1918, he wrote a phenomenal essay winning him a scholarship to the Scub Normale Superiore University in Italy, this essay also promoted him immediately to the doctoral program.
Everything around us is made of atoms. Most objects are mixtures or compounds of different types of atoms, but some common items consist of only a single type of atom. Each image here represents a common item that is composed of only one or a few elements.

My scientist’s name is Max Planck. He is a very well known man for the discovery of energy. Max planck was born on April 23, 1858 in kiel, Germany. Max Planck made many contributions to theoretical physics, but his fame rests primarily on his role as the originator of the Quantum theory. This theory revolutionized our understanding atomic and subatomic processes, just as Albert Einstein’s theory of relativity revolutionized our understanding
