One of the little known facts about Albert Einstein was his love for music. This part of him was given due recognition in 2005, the World Year of Physics, when Peregrine White described him as “…two parts renowned scientist, one jigger pacifist and Zionist fundraiser, and a dash amateur musician.” More often than not, when Einstein’s achievements are remembered, his the- ories on relatively are the star of the show. Consider this short write-up as an attempt to re-establish the bal- ance of Einstein the physicist and Einstein the musician. Armed with his trusty violin, “Lina”, Einstein the amateur violinist would often create chamber music with a chosen few. He fell in love with the works of Mozart at age 13, and never stopped learning since then. Even at the height of his career as a scientist, he was said to have kept a weekly schedule for chamber music sessions. Wednesday nights were always strictly for mu- sic. Einstein has contributed to more than our perception of reality. He has truly set the bar high for an amateur musician. More than talent and passion, it takes determination to merge two different worlds together in a satis- fying balance of logic and creativity. That being the case, it is not uncommon for a group of passionate individuals specializing in the sciences to share a special interest in the arts. In a world of problem sets, machines, theorems, and simulations, these people find comfort in the chords and clashes that create one of the most loved real-world signals – music. A single voice may be audible, but with the harmony of the whole choir, it multiplies three-fold. Equipped with the best voices from the National Institute of Physics, NIP Resonance brings you the most spectac- ular show on Earth - life. EINSTEIN COLLECTION

This Einstein collection is owned by Alexis De La Torre. “Lex” is a Chemical Engineer who works for the national oil company as a business and planning analyst. His fondness for the sciences and mathematics led him to choose a degree and a career that combines both. He is also a member of MENSA Philippines, the local chapter of MEN- SA International, the world’s largest and oldest high IQ society.

His collection includes an eclectic mixture of statues, action figures, stamps, bobbleheads and other memorabilias. Some highlights of his collection include an authenticated piece of wood from the “” in , Swit- zerland, several stamps commemorating Einstein’s life and other significant historical events, vintage trading cards from the 1950’s, A limited edition Fossil Einstein watch, high-end one-sixth scale figures and other famous char- acters dressed up as Einstein, such as Winnie the Pooh, Garfield, M&M mascots and others. He hopes to acquire the grail of his collection one day, and that is the actual autograph of Albert Einstein.
