Silly Job Title: Digital Dancer. I am the Digital Dancer!

In this video we unbox the Sharp EL-506TS scientific calculator. In this video I also mention about my Casio fx-991CW and my Sharp EL-546L.

The constants used in the calculator are taken from CODATA Recommended Values of the Fundamental Physical Constants: 2018 which is an impressive scholarly work.
