In the scientific radio program "Researchers Around the World", number 262, presented and directed by Antonio G. Armas, which aired on Radio Libertad on Tuesday 12/11 between 19:30-20:00 h, we interviewed Dr. Ángel Miranda Vicario. He has been working for more than 10 years at the Royal Military Academy in Brussels (R) in the weapons systems and ballistics department, specializing in terminal ballistics and personal protection. He completed his doctorate in 2020, alongside the University of Burgos, where he studied the possibility of stopping a rifle bullet with a helmet. He has worked on several projects studying how to improve ballistic protection, typically for soldiers. We thank the Association of Spanish Researchers in Belgium for their collaboration in producing this interview.
