Mihai Gavrilă (Romanian pronunciation: [miˈhaj ɡaˈvrilə]; b. October 16, 1929, Cluj) is a Romanian quantum physicist, member of the Romanian Academy since 1974. He made fundamental contributions to quantum theories of electromagnetic interactions with atoms. His parents were Ion and Florica Gavrilă (née Vișoiu). His father taught medicine and his mother taught English at the University of Cluj.

He began his higher education at the Gheorghe Lazăr High School in Sibiu, and completed his studies at the Seminarul Pedagogic Universitar of the University of Cluj. Then, in 1948, he enrolled in the School of Mathematics and Physics of the University of Bucharest from which he graduated with a major in physics, and a minor in radiotechnology, in 1953. While still a student, between 1951 and 1953, he became a teaching assistant to Professor Eugen Bădărău in the Optics Laboratory of the School of Physics.

In 1953, he was accepted for doctoral studies in theoretical physics by Acad. Professor Dr. Șerban Țițeica in the School of Physics at the University of Bucharest, and completed successfully his doctoral studies with the Ph.D. thesis entitled ``The Relativistic Theory of the Photoelectric Effect", apparently following in Albert Einstein's and Alexandru Proca's footsteps. He published in 1959 the main results of his Ph.D. thesis in a peer-reviewed paper in Physical Review.

Alessandro Stradella (Nepi, 3 April 1639 – Genoa, 25 February 1682) was an Italian composer of the middle baroque. He enjoyed a dazzling career as a freelance composer, writing on commission, collaborating with distinguished poets, producing over three hundred works in a variety of genres.

Not much is known about his early life, but he was from a Tuscan aristocratic family, educated at Bologna, and was already making a name for himself as a composer at the age of 20. In 1667 he moved to Rome where he composed for Christina, Queen of Sweden, mostly sacred music. He was involved in performances of four operas, two by Francesco Cavalli and two by Antonio Cesti. Stradella began to live a dissolute life. With Carlo Ambrogio Lonati he attempted to embezzle money from the Roman Catholic Church, but was found out: he fled the city, only returning much later when he thought it was safe. His numerous incautious affairs with women began to make him enemies among the powerful men of the city, and he had to leave Rome for good.
