Cosmic ray physicists are scientists who study cosmic rays, which are high-energy particles originating from outer space that travel through the Earth's atmosphere and can reach the surface. These particles mainly consist of protons, atomic nuclei, and, to a lesser extent, electrons and positrons. Cosmic rays can originate from various astrophysical phenomena, including supernovae, active galactic nuclei, and other high-energy astrophysical events.

Cosmologists are scientists who study the universe as a whole, including its origins, evolution, structure, and eventual fate. They seek to understand fundamental questions about the cosmos, such as the nature of dark matter and dark energy, the formation and evolution of galaxies, the cosmic microwave background radiation, and the overall geometry of the universe. Cosmologists often utilize principles from physics and astronomy, employing both observational data and theoretical models to develop their understanding of the universe.

Crystallographers are scientists who study the arrangement of atoms within crystalline solids. Their work involves analyzing the structure of crystals to understand their physical and chemical properties. This field of study, known as crystallography, often utilizes techniques such as X-ray diffraction, neutron diffraction, and electron diffraction to determine how atoms are organized in a crystal lattice. Crystallographers play a crucial role in various applications, including materials science, chemistry, biology, and solid-state physics.

Experimental physicists are scientists who investigate physical phenomena by conducting experiments to gather data and test theoretical predictions. Their work often involves designing and building experimental setups, using sophisticated instruments, and analyzing data to understand the fundamental principles of nature. The main roles of experimental physicists include: 1. **Designing Experiments**: They create experimental protocols to test specific hypotheses or explore new phenomena.

"Lists of physicists by field" typically refers to organized compilations of physicists categorized according to their specific areas of expertise or research within the broad field of physics.

Some common categories or fields within physics that such lists might include are: 1. **Theoretical Physics** - Physicists who primarily focus on developing theories and models to explain physical phenomena.

Particle physicists are scientists who study the fundamental components of matter and the forces that govern their interactions. Their work primarily focuses on subatomic particles, such as quarks, leptons (which include electrons and neutrinos), bosons (such as photons and gluons), and other exotic particles that may arise in theoretical frameworks. The field of particle physics seeks to answer fundamental questions about the universe, such as: 1. **What are the basic building blocks of matter?

Physical chemists are scientists who study the physical properties and behavior of chemical systems. They combine principles of physics and chemistry to understand how matter behaves on a molecular and atomic level. This interdisciplinary field involves the application of various techniques and theories from both disciplines to investigate chemical processes, reaction mechanisms, and the energy changes associated with chemical reactions.

Pseudoscientific physicists refer to individuals who claim to practice or speak about physics but whose ideas or theories lack empirical evidence, rigorous scientific methodology, or peer-reviewed validation. They may promote concepts that seem to be scientific but do not adhere to the established principles of the scientific method and are often not accepted by the mainstream scientific community.
