Blas Roca Calederio, born on July 22 in 1908, was a Cuban communist revolutionary and radical journalist. Roca helped lead the 1933 general strike that ousted Gerardo Machado, and served in Fidel Castro's revolutionary government.

Born into a poor family, Roca began working at age eleven, shining shoes. According to Castro, Roca was already a prominent communist organizer in the province of Oriente at 21 years old.

At age 25, Roca helped lead a two week general strike that ousted dictator Gerardo Machado. By 1936, he was head of the Cuban Communist Party and began serving as a politican, helping author the 1940 Cuban Constitution.

Under Roca's leadership, Cuban communists were instrumental in providing an organizational and ideological structure for Castro's revolution, as well as playing a pivotal role using the party's long-standing ties with the Soviet Union to promote increasingly closer ties during the early days of the revolution.

In 1961, Blas Roca, leading a party delegation, presented a Cuban flag to Nikita Khrushchev during a meeting of the Communist Party of the Soviet Union. Roca served on the first central committee and politburo of the new Communist Party of Cuba, founded in 1965.

    Anxiety has me constantly flipping around. Current rotation: graduate stats book, Bishop's new deep learning book, nonlinear PDE book from my graduate studies.

    I really want to pivot out of data science into something more math or engineering heavy, but having it hard to decide on what. I'm thinking potentially something DSP related, maybe fiberoptics reseadch. My academic work was in nonlinear waves so I was like surely some lab is doing research on fiberoptics with some small imperfection? There's gotta be nonlinear schrodinger or nonlinear wave equations in that, right??

      Niceeee

      You would think there would be given how much data they push through those things now, tiny imperfections and weird impedance mismatching, scattering, etc matters so much now that theres like nanosecond intervals between each symbol or whatever lol. Would guess the modeling involved there is on another level

      Idk anything about the math involved though, they didn't even teach me calculus in high school :(

      I hope you can find some work to do more interesting to you, in your field even
