IJMP wishes to congratulate all medical physicists on their international day (November, 7). On that day in 1867, Marie Sklodowska-Curie, known for her pioneering research on radioactivity, was born in Poland. The theme of IDMP 2015 is ‘Better Medical Physics = Better Cancer Care in Radiation Oncology’. This is an excellent opportunity to promote the role of medical physicists in the worldwide medical scene.
