What is the maths you really need in Data Science?
Highly debatable subject, especially because the job title "Data Scientist" is still fluid and it means different things to different...
Following a career in IT, I spent 20+ years in physics (MSc in Nuclear Physics, Turin, Italy, and a PhD in plasma physics, Cranfield, UK).
After several years in academia, in 2008 I moved to private companies working in R&D and, since 2014 in Data Science,
My passions include Science and Languages.
I teach programming and Data Science and occasionally blog on these matters..
Current interest: Deep Learning, IoT, Time Series, and Rare Events.
