Hi, my name is Fajrul Falah a.k.a Fajrul Fx 👋

I have a diverse range of skills and experience in physics, education, and media.

I mainly identify myself as:

  • Science Communicator – I create popular science content, especially about physics, in an exciting way on Youtube. Currently, my channel has snowballed to 40M+ views, 400k+ subscribers.
  • Amateur Physicist – I love to play with physics, but I’m not that smart. Previously, I worked as a physicist at DTECH-ENGINEERING company, and currently, I continue studying physics (M.Sc) at the School of Physics and Astronomy at Cardiff University, UK.

Work Experiences:

    (Jun 2019 – May 2021)
    I did physics analysis and calculation for various technology products, such as: 5-axis CNC milling, cargo drone, racing bike engine, and many more.
  • Founder and CEO, Saintif
    (2017 – 2020)
    Saintif.com is an online popular science media that focus on bridging the gap between science and society. It already has 10M+ website visitors and 70K+ Instagram followers. We’ve now pivoted to Youtube to open up new opportunities and make a bigger impact.
  • Physics Laboratory Assistant, Bionano Material Lab, Diponegoro University
    (Aug 2018 – Jul 2019)
