Prospective Physics Graduate Students

Photo: A. Photo: D. As an undergraduate, I pursued a double degree in mathematics and anthropology. Both subjects enthralled me — I loved the elegance and logic of math as well as the mystery and adventure of anthropology, especially archaeology. I saw links between the two seemingly disparate subjects, whereas my advisors and almost anyone else with whom I shared one or the other of my twin loves reacted much differently. Most raised an eyebrow, and I was met with puzzled faces. There are physicists who work on archaeological and other anthropological problems, physicists who have made career transitions into archaeology, and archaeologists who leverage their physics background to solve archaeological problems.

History of physics

Physics is the study of motion, matter, and energy. It is the most fundamental of sciences, and provides the essential underpinning of chemistry, biology, astronomy, and geology. Physicists probe the structure of atomic nuclei, study exotic states of matter that occur at ultra-low temperatures, and develop theories that predict the origin and destiny of the universe. Physics has practical applications to a wide variety of tasks such as fabricating very large scale integrated circuits, producing high efficiency solar cells, and developing nanomachines, high-power lasers, and scanners for imaging activity within the human brain.

During the first half of the twentieth century—actually, the first quarter—there were two major scientific revolutions. Those cognitive cataclysms took place in physics, and are known as the relativist and quantum revolutions. Much has been written, and will be written in the future, about the importance of those theories and their effect on physics as a whole, even before the middle of the century. For example, this theory helped explain how it was possible that radioactive elements uranium, polonium, radium, thorium that had been studied for the first time by Henri Becquerel and Marie and Pierre Curie , emit radiation in a continuous manner with no apparent loss of mass.

And then there was the general theory of relativity, which explained gravity by converting space—actually, four-dimensional space-time—into something curved, and with variable geometry! As if that were not enough, Einstein himself had the intellectual daring to apply his general theory of relativity to the overall Universe, thus creating cosmology as an authentically scientific and predictive field. While it is true that the model Einstein proposed at that time, in which the Universe is static, did not survive in the end; what matters is that it opened the doors to a scientific approach to the Universe, which makes it an almost unprecedented event in the history of science.

To find the exact solution to the equations of relativistic cosmology he was using, Einstein employed physical considerations. Other mathematicians or physicists with special sensibilities and mathematical skills followed a different path, quickly finding new exact solutions—which implicitly represented other models of the universe—based exclusively on mathematical techniques, which they used to address the complexities of the equations of relativistic cosmology a system of ten non-linear equations in partial derivatives.

All of these models arose from solutions of cosmological equations; that is, they addressed theoretical possibilities.

Chris McKinlay was folded into a cramped fifth-floor cubicle in UCLA’s math sciences building, lit by a single bulb and the glow from his monitor. The subject: large-scale data processing and parallel numerical methods. While the computer chugged, he clicked open a second window to check his OkCupid inbox. McKinlay, a lanky year-old with tousled hair, was one of about 40 million Americans looking for romance through websites like Match.

He’d sent dozens of cutesy introductory messages to women touted as potential matches by OkCupid’s algorithms. Most were ignored; he’d gone on a total of six first dates.

Physics is a branch of science whose primary objects of study are matter and energy. Discoveries of physics find applications throughout the natural sciences and in technology , since matter and energy are the basic constituents of the natural world. Some other domains of study—more limited in their scope—may be considered branches that have split off from physics to become sciences in their own right.

Physics today may be divided loosely into classical physics and modern physics. Elements of what became physics were drawn primarily from the fields of astronomy , optics , and mechanics , which were methodologically united through the study of geometry. These mathematical disciplines began in antiquity with the Babylonians and with Hellenistic writers such as Archimedes and Ptolemy.

The move towards a rational understanding of nature began at least since the Archaic period in Greece — BCE with the Pre-Socratic philosophers. The philosopher Thales of Miletus 7th and 6th centuries BCE , dubbed “the Father of Science” for refusing to accept various supernatural, religious or mythological explanations for natural phenomena , proclaimed that every event had a natural cause.

Major in Physics

A s the school year gets underway and millions of matriculating students consider which major to choose , we got to wondering: Which degrees are most romantically compatible with one another? Are an anthropologist and an art historian intrinsically more likely to get together than, say, and English major and a physicist? Now, we have the data to answer that question. In almost every case, like attracted like.

Last summer, researchers at Yale published a study proving that physicists, chemists and biologists are likely to view a young male scientist more favorably than a woman with the same qualifications. Presented with identical summaries of the accomplishments of two imaginary applicants, professors at six major research institutions were significantly more willing to offer the man a job. Surprisingly, female scientists were as biased as their male counterparts.

The new study goes a long way toward providing hard evidence of a continuing bias against women in the sciences. Only one-fifth of physics Ph. The numbers of black and Hispanic scientists are even lower; in a typical year, 13 African-Americans and 20 Latinos of either sex receive Ph. The reasons for those shortages are hardly mysterious — many minority students attend secondary schools that leave them too far behind to catch up in science, and the effects of prejudice at every stage of their education are well documented.

As one of the first two women to earn a bachelor of science degree in physics from Yale — I graduated in — this question concerns me deeply. When I arrived at Yale, I was woefully unprepared. The boys in my introductory physics class, who had taken far more rigorous math and science classes in high school, yawned as our professor sped through the material, while I grew panicked at how little I understood.

The only woman in the room, I debated whether to raise my hand and expose myself to ridicule, thereby losing track of the lecture and falling further behind. At the end of four years, I was exhausted by all the lonely hours I spent catching up to my classmates, hiding my insecurities, struggling to do my problem sets while the boys worked in teams to finish theirs.

How is Earth’s Age Calculated?

When asked for your age, it’s likely you won’t slip with the exception of a recent birthday mistake. But for the sprawling sphere we call home, age is a much trickier matter. Before so-called radiometric dating, Earth’s age was anybody’s guess. Our planet was pegged at a youthful few thousand years old by Bible readers by counting all the “begats” since Adam as late as the end of the 19th century, with physicist Lord Kelvin providing another nascent estimate of million years.

Kelvin defended this calculation throughout his life, even disputing Darwin’s explanations of evolution as impossible in that time period.

Carbon dating is a variety of radioactive dating which is applicable only to matter which was once living and presumed to be in equilibrium with the atmosphere, taking in carbon dioxide from the air for photosynthesis. Cosmic ray protons blast nuclei in the upper atmosphere, producing neutrons which in turn bombard nitrogen, the major constituent of the atmosphere. This neutron bombardment produces the radioactive isotope carbon The radioactive carbon combines with oxygen to form carbon dioxide and is incorporated into the cycle of living things.

The carbon forms at a rate which appears to be constant, so that by measuring the radioactive emissions from once-living matter and comparing its activity with the equilibrium level of living things, a measurement of the time elapsed can be made. Presuming the rate of production of carbon to be constant, the activity of a sample can be directly compared to the equilibrium activity of living matter and the age calculated. Various tests of reliability have confirmed the value of carbon data, and many examples provide an interesting range of application.

Carbon decays with a halflife of about years by the emission of an electron of energy 0. This changes the atomic number of the nucleus to 7, producing a nucleus of nitrogen At equilibrium with the atmosphere, a gram of carbon shows an activity of about 15 decays per minute.

BIOGRAPHY NEWSLETTER

That the top minds in theoretical physics have been spending their time on theories that not only may never be validated, but might not have made any concrete and useful predictions. Because I had aborted my physics education and training before reaching string theory or general relativity, for that matter , and so it was really not my problem. But I thought the book might provide a means to catch up with all that I had missed, in a form digestible by a general audience, hence requiring none of the physics knowledge that had long since left me due to disuse.

In , Antoine Becquerel discovered that a uranium-rich rock emits invisible rays that can darken a photographic plate in an enclosed container. Scientists offer three arguments for the nuclear origin of these rays. First, the effects of the radiation do not vary with chemical state; that is, whether the emitting material is in the form of an element or compound.

Second, the radiation does not vary with changes in temperature or pressure—both factors that in sufficient degree can affect electrons in an atom. Third, the very large energy of the invisible rays up to hundreds of eV is not consistent with atomic electron transitions only a few eV. Today, this radiation is explained by the conversion of mass into energy deep within the nucleus of an atom.

When an individual nucleus transforms into another with the emission of radiation, the nucleus is said to decay. The decay rate is proportional to the number of original undecayed nuclei N in a substance. The minus sign indicates the number of original nuclei decreases over time. In other words, the more nuclei available to decay, the more that do decay in time dt.

The half-lives of unstable isotopes are shown in the chart of nuclides. The number of radioactive nuclei remaining after an integer n number of half-lives is therefore.
