Got this as a gift from Akshay. This has all the elements of stuff I like – math, writing with fountain pen and something completely quirky.

As you see, the name of the notebook is “Nonstandard Notebook” – Mathematically Ruled Pages for Unruly Thoughts!!

Check out the Contents page. I have also included two sample pages – “herringbone” and “rupture” curves and the mathematical equations that give rise to those lines!!

Love writing on it!
