Does NASA hire theoretical physicists?

NASA employs theoretical physicists in research roles related to astrophysics, space science, and fundamental physics, often requiring advanced degrees such as a Ph.D. and strong analytical skills. These positions may involve developing models, simulations, and contributing to scientific missions, typically within research or engineering teams. Candidates should have expertise in physics, mathematics, and relevant programming tools.

What are the key skills and qualifications needed to thrive as a theoretical physicist?

Excelling as a Theoretical Physicist requires advanced expertise in physics and mathematics, typically supported by a Ph.D. in physics or a closely related field. Familiarity with computational modeling tools (such as MATLAB or Mathematica), programming languages (like Python or C++), and scientific publication systems is common. Critical thinking, problem-solving, and the ability to communicate complex ideas clearly are valuable soft skills in this role. These abilities allow Theoretical Physicists to develop and test new theories, contribute to innovative research, and effectively share their findings with the scientific community.

What jobs can a theoretical physicist get?

A theoretical physicist can work in academia as a researcher or professor, in government laboratories conducting fundamental research, or in industry roles such as data analysis, software development, or technology consulting. They often utilize strong analytical, mathematical, and programming skills, and may require advanced degrees like a Ph.D. to qualify for research positions.

What does a typical workday look like for a theoretical physicist?

A typical day for a Theoretical Physicist often involves formulating and refining mathematical models, running computer simulations, and analyzing data to explore physical phenomena. They may spend time collaborating with experimental physicists, attending research meetings, or reviewing scientific literature to stay current in their field. Writing and revising research papers, preparing for conferences, and mentoring graduate students or team members are also common activities. The work environment is usually a blend of independent research and teamwork within academic institutions, research centers, or government laboratories.

What work do theoretical physicists do?

Theoretical physicists develop mathematical models and use complex calculations to understand fundamental principles of the universe, such as the nature of matter, energy, space, and time. They often work in research institutions or academia, utilizing tools like computer simulations and advanced mathematics to test hypotheses and predict phenomena.

What does a theoretical physicist do?

A Theoretical Physicist studies the fundamental laws of nature by developing mathematical models and theories to explain physical phenomena. They work on abstract concepts such as quantum mechanics, relativity, and cosmology, often without direct experimentation. Their work can lead to new scientific discoveries, influence experimental research, and contribute to advancements in technology. Many Theoretical Physicists work in academia, research institutions, or industries like aerospace and computing.

Job description

Computational Physics, Inc. (CPI) is looking for an Experimental Atomic Physicist to support our customers at the U.S. Naval Observatory (USNO).

Background

The USNO is responsible for the creation, dissemination and maintenance of precise time and navigation products for the Department of Defense and other customers. CPI is seeking an Experimental Physicist with a background in atomic, molecular or optical physics to support next-generation atomic clock development at USNO. The successful candidate will support the work of the Clock Development division on optical lattice clocks and cold-atom beam optical clocks based on alkaline earth atoms. The new Physicist will work with a team of CPI contractors and USNO Scientists to develop robust solutions for high-uptime optical clocks and the infrastructure for their integration into the USNO timescale.

Most work for this position will be completed on-site at USNO in Washington, D.C.; occasional travel to conferences within and outside of the continental United States may be required based on the needs of the customer. Relocation assistance is available. The successful candidate must be able to obtain and maintain a SECRET security clearance upon hiring, an active clearance is not required at the time of application. The new Physicist will work closely with other CPI contractors and federal employees in the Precise Time Department, providing periodic updates to the Clock Development Division Chief.

Basic Qualifications

  • PhD in Experimental Atomic Physics or similar field
  • At least 6 years of experimental physics experience, this can include relevant work toward an advanced degree.
  • Data analysis using Python or similar programming language
  • Familiarity with lasers, optics and atomic spectroscopy
  • Familiarity with feedback control theory and electronics
  • Excellent verbal and written communication skills

Desired Qualifications

  • Atomic clocks
  • Laser cooling and trapping of alkaline-earth atoms
  • Diode lasers and optical frequency combs
  • Hands on experience with python-based experimental control (e.g. ARTIQ)

Candidate must obtain a SECRET clearance upon hiring.

U.S. citizenship is required for DoD contracts.
