On behalf of the GIREP-ICPE-EPEC-MPTL Eötvös Year 2019 organizing committee, we are honoured and delighted to welcome you to our conference which will be between 1st and 5th of July 2019. We believe that we have chosen a venue – the Budapest University of Technology and Economics – that guarantees a successful event amid the culture and beautiful world-heritage scenery of Budapest, Hungary. This conference is coinciding with the memorial year of Roland Eötvös for his passing a century ago. Also the UNESCO is associated to commemorate his achievements in physics in 2019. Roland Eötvös (1848-1919) was a Hungarian physicist, who was not only an outstanding scientist – measuring the strict proportionality of the inertial and gravitational masses to a precision unprecedented before –, but was also an excellent educator and reformer of the Hungarian science education system. We do hope that the scientific program of the conference will be rich and varied. We reserved slots for keynote speeches and several parallel sessions enabling to present many works about physics education practices and physics education research. The posters can be on show during the whole conference. We have also included scientific visits into the program (with no extra fee), which will give the opportunity to visit sites that would not be reachable otherwise. Those visits will help physics educators to gather personal impressions about outstanding physics research laboratories or installations whose operation is strongly based on achievements of modern physics. These personal impressions can be further distributed to thousands of pupils and students.
