„It is wrong to think that the task of physics is to find out how nature is. Physics concerns what we can say about nature.“ (Niels Bohr: „Atomic Theory and the Description of Nature“, 1931)


IAF’s strength lies in the interdisciplinary collaboration of physicists, chemists and engineers work with experienced laboratory assistants and technicians. Experience and continued professional development of all team members are key to our and our client’s success.
