FOUR THIRDS PI R3
I infinitely thank Lucia Amendola Ranesi, together with Mari’s Manual, for the opportunity to discover the book Quattro Terzi Pi Greco Erre Tre which I loved very much.
What is the volume of the sphere? Four Thirds Pi r3.
It is not the first time that I have told my interest in books on mathematics, but in this case I was immediately struck by the affinity of thought.

And it shows how pure and true love cannot in any way be dirtied.
I will certainly not forget a special Grandmother, whom I wish I could hug as she repeats that all soldiers are sons.
And a special woman: Maria Moreno, who I hope will be remembered for her ability to combine literary and scientific studies, delicacy and strength of mind, poetry and everyday life.
Obviously I tend to focus more on the female characters, but undoubtedly Rodolfo too, as well as two important figures who have left a mark on our history, offer very interesting reflections.

In a book so close to my heart, could coffee be missing?!
Obviously not! In fact, here it is:
