Physics is a broad field that includes theoretical and applied physics. Theoretical physicists use math to understand natural forces and phenomena, while applied physicists conduct experiments to confirm physical laws. Physicists work in research and development, teaching, and writing. A doctorate is typically required to become a physicist. Physics is a branch of science that […]
A physics professor’s job involves teaching college students on physics-related topics, conducting research, publishing findings, lecturing at local and foreign universities, and winning prizes or awards. A doctorate in physics is required to become a professor. Although a physics professor is responsible for instructing college students on physics-related topics, there are many other aspects to […]
The boundary layer is the region of fluid whose velocity is less than 99% of unobstructed fluid flow. It separates laminar and turbulent flow zones, with laminar flow being smooth and predictable, and turbulent flow being random and violent. Golf balls have dimples to reduce air friction in high-speed flight. A boundary layer occurs when […]
Phonons are energy particles found in vibrating objects, such as quartz crystals, and are a part of quantum mechanics. They interact with other phonons, forming chains or lattice structures, and can transfer energy in the form of electricity or heat. Manipulating phonons could lead to breakthroughs in creating efficient conducting or insulating materials, and practical […]
Mass physics studies the properties of mass in relation to forces. Weight is the measure of gravity needed to keep objects on Earth, while mass is the amount of matter in an object. Mass is divided into gravitational and inertial mass, which can be measured using known objects and Newton’s law of motion. Mass physics […]
Electron volts (eV) are a small unit of energy used in physics research, derived from the energy required to move a single electron through an electrical potential of one volt. They are used in fields such as nuclear and particle physics, astronomy, and chemistry. While not a standard metric unit, they can be used to […]
Physics and metaphysics are two different methods of describing reality. Metaphysics is concerned with what is beyond science and sometimes replaces scientific knowledge. In the past, physics that contradicted metaphysical knowledge was considered heretical. However, there is now greater acceptance of scientific ideas. The discovery of quantum particles has caused people to reevaluate the relationship […]
Physics experiments observe physical phenomena to gain knowledge about the universe. High school experiments demonstrate basic principles, while college experiments are more advanced. Theoretical physics often involves untestable equations, but experimental physics is crucial. The cost of experiments is increasing due to the need for incredibly small or massive subjects. The Large Hadron Collider is […]
Particle physics and cosmology are closely linked, with the study of the Big Bang and black holes being particularly relevant. Cosmologists need to understand particle physics to create plausible models, and particle accelerators are used to simulate early universe conditions. Dark matter and dark energy are also important questions in modern cosmology. There is an […]
Sequestration is a proposed way to confine certain particles and forces to extra dimensions, solving problems in particle physics. It is relevant to string theory, M theory, and supersymmetry. Sequestration can solve the hierarchy problem while avoiding flavor violation. Supersymmetry theory provides one possible explanation, but there is a problem with supersymmetry. Sequestration can prevent […]
Nuclear physics studies atomic nuclei and their manipulation. It has many applications, including medical imaging, cancer treatment, nuclear engineering, and radiocarbon dating. A career in nuclear physics requires a bachelor’s degree and graduate-level work. Nuclear physics is a branch of the field of physics concerned with the structure of atomic nuclei and with understanding potential […]
Physics professors teach physics at various levels, including high school and university. They may also work as tutors and belong to professional organizations. Some specialize in general education while others offer advanced topics, and workplace physics programs may also be available. A physics professor is a professor who provides instruction in physics. To become a […]
Vector physics studies forces that change the direction and speed of a moving body. Vectors are represented by arrows of variable length and direction on a Cartesian plane. Vector analysis predicts the impact of natural forces on matter in motion. Simple vector physics problems can be solved by constructing a parallelogram. More complex problems can […]
Interference in physics can refer to wave interference or communication interference. Wave interference occurs when two or more waves meet, resulting in a change in amplitude. There are two types: constructive and destructive. Coherent waves with similar frequencies can create a coherent interference pattern. Communication interference refers to distortion in radio wave signals. Electromagnetic waves […]
Coherence length is the maximum distance a wave can travel while maintaining temporal coherence. It is influenced by factors such as wavelength and scattering. Applications include holography and telecommunications. In optics, which is the branch of physics that deals with light and its properties, the coherence length (CL) is the maximum distance that a ray […]
Earning an online physics degree requires a strong math and science background, dedication, and willingness to deal with potential challenges. Accreditation, reputation, and access to professors are important factors to consider when choosing a school. A bachelor’s degree can lead to technician or research assistant jobs, while a PhD is required for most research and […]
Physics is studied through experimentation, with physics laboratories providing the necessary instruments for measuring and testing motion, light, heat, and force. There are various disciplines within physics, and modern labs use computer simulations alongside traditional experiments. Theoretical physicists use simulations to prove hypotheses, while experimental physicists perform classical experiments. Both approaches are important for advancing […]
Becoming a physics professor requires years of studying and research. High school success in math, physics, and chemistry can lead to university opportunities, followed by graduate school and professional connections. Securing a professor position is difficult, but placement programs and research can help. To become a professor of physics, one must spend many years studying […]
A physics teacher teaches physics in schools, usually starting in middle or high school. To become a physics professor, one must attend college and earn a degree in physics, obtain teaching certification, and complete student teaching. Physics professors teach topics such as mechanics, electricity, and magnetism, and may also cover advanced topics like quantum mechanics […]
Isaac Newton was more interested in religion than physics or mathematics, spending countless hours researching and writing about Christianity. He sought to discover the real truth about God and Jesus through the study of ancient manuscripts, but died before completing his five-volume account. Newton may have seen an apple fall from a tree, but did […]
