Yesterday I said about my intend to memorize 2 k of pi in one day. But then I received a call from my childhood friend and we decided to meet. I wasn't able to use my laptop at the metro ( aka subway) while I was traveling to meet him. So, I downloaded file with numbers on my phone and guess what. It’s not so bad as expected. I mean in 2017 it’s easy to use your phone for study, even on the go. Of course, you can’t do some kind of work at your smartphone, but memorizing Pi number – not so bad.
