What helps you succeed in applying for a management position in the private sector might be a deal-breaker at university – and vice versa.
Physicists working in the private sector can expect a salary significantly higher than average. If physicists remain in teaching and research, diverse opportunities are available, but are associated with a fairly average income.
British universities are regarded in Germany as the benchmark for all reforms. This is absurd.
A doctoral degree will certainly only help you to become rich in an idealistic sense. The first contract for a PhD position should have a term of at least one year - after which, graduates are rewarded with their first salary increase.
