About simpliphy

Simpliphy is a personal blog written by me, Dwi Prananto. I am an experimental physicist with a regular job of nudging tiny “spinning” objects with electromagnetic wave to see how they interact with their fellow tiny objects and to take a photo of them in action.

The word Simpliphy is an abbreviation of simplify physics. As the name says this blog is intended mainly as a media for me to explain physics in words that can be understood by general public. Beside, I also write about various other topics and hobbies beyond physics. This blog is mostly written in my native language, Bahasa Indonesia.

I will be happy to interact with you on Twitter!
