Possible challenges before choosing this path.
Most serious physicist roles require M.Sc or PhD-level training, which creates a long preparation timeline.
Thermal physics is specialized, so role availability may be concentrated in universities, labs, R&D centres and specific industries.
Project roles and fellowships may depend on grants, institute funding, contract duration and publication performance.
Academic and research careers may require regular publications, conference presentations, proposals and research output.
Experiments involving high temperature, cryogenics, vacuum, electrical equipment or chemicals require strict safety procedures.
Pure theory may not directly lead to industry roles unless combined with simulation, data analysis, instrumentation or applied thermal systems.
