FOUR THIRDS PI R3

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.

Starting with a formula to tell a story

Or starting from a story to tell a formula.

Actually both.

The “formula” to which one arrives, however, is not a calculation, but a journey that leads, or rather: brings back, to the origin.

I don’t like to reveal too much, because I would like you to try the same engaging reading experience that I had, and I would like you too to come to the “full circle” with all the load of emotions that accompanied me.

I considered Quattro Terzi Pi Greco Erre Tre as the equation of a world in which to enter through a wonderful exchange of letters, precisely those handwritten letters, the letters  so dear to me.

A family sphere, but also a historical sphere.

And through the life of the characters I first understood the vocation: the passion for studying and teaching, together, as in a real union that lasts for a lifetime.

But the book also teaches that fate is not always behind the things that scare us the most.

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.

What if I told you Renato Caccioppoli? What if I told you Ettore Majorana?

In a book so close to my heart, could coffee be missing?!

Obviously not! In fact, here it is:

WHERE A POEM CAN ARRIVE

WHERE A POEM CAN ARRIVE

Today the Advent calendar gives us the tiptoe story of the blog Where a poem can arrive

On tiptoe because she talks about classical dance, but on tiptoe also for how Laura, the author, introduces herself and presents her story.

Laura is enrolled in the Faculty of Engineering of the Polytechnic and for me she is automatically esteem, but at the same time she describes herself as a dreamer with a great desire to travel the world and with a whole series of characteristics that I particularly love.

Laura is 19 and has already written a lot
The name of the blog is Where a poem can arrive, and it is difficult to find an answer, but perhaps it is easier to say Where Laura can arrive and I wish it, because she really deserves .

And in the meantime she brings us to none other than Juilliard where her dance partner won a scholarship, and where she set her story Nutcracker in New York:

Snow fell heavily over New York City. It covered the roofs of the houses, the streets, the street lamps, the bare trees, everything was becoming white and the Christmas atmosphere was starting to be felt under the sky of the Big Apple. Ally was on her way to Juilliard, the dance school where she had been studying for three years now, with the bag on her right shoulder and the i-pod playing the notes of the candy fairy dance in her left handgo on here

WHERE A POEM CAN ARRIVE

TUTTOLANDIA

The days go by and we are already at box number 7 of the Advent Calendar, The world of Shioren announced that the creations would include a bit of everything… we started with a drawing, then we had tales and a video.

Today Tuttolandia gives us a poem.

So far, in some cases more, in some cases less, I had first met the authors of the various blogs participating in this initiative, but in the case of Tuttolandia I am faced with a surprise in the round.

Reading what Paola writes about herself, I discover many aspects that unite us, and I smile at the thought of how fate sometimes makes us cross people in the strangest ways.

As I wrote in the comments to Paola, reading the poem she wrote immediately transported me to the kind of Christmas atmosphere that I particularly love. 

Light.
I feel the need for that light so much, and I think it should be a little bit like this for everyone.

You will tell me after reading The Tree and the Star:

The fir

master of the room

fondles himself as

a princess

coated

from rosy crystals

and thirst for

light ribbons.

FOUR BOOKS ON MATHEMATICS AND SEVEN SHORT PHYSICS LESSONS

FOUR BOOKS ON MATHEMATICS AND SEVEN SHORT PHYSICS LESSONS

Pure mathematics is, in its way, the poetry of logical ideas.
Albert Einstein

Mathematics = one of the most difficult subjects for many people, while for someone it is a “cup of tea.”
Which category do you belong to?

These books, for which I sincerely thank Franca, Vincenzo and Francesco, although very different from each other, fit the concept expressed by Einstein.

1. UNCLE PETROS AND THE GOLBACH CONGECTURE

Now Stellan Skarsgard talking about Hardy and Ramanujan to Robin Williams in Good Will Hunting makes sense to me too.

 

A book on mathematics but also the book on the life of a man who has to deal with his obsession.

2. HAPPY MATHEMATICS

My dear kids, I have written this book for you …
so the author addresses the readers, the students, his children.

I was struck by these words, which apparently have nothing striking, which could be attributable to many professors in fact, but which I read differently considering that Angelo Luigi Fiorita lost his children during a bombing on Alessandria on April 5, 1945

3. MATHEMATICS AMAZING AND POETRY

 

Here we pass from the colloquial tone and expressly dedicated to children, to a vision of mathematics as humanism, it is no coincidence that Bruno D’Amore also graduated in philosophy.

Do you know the concept of Technoracy?
Technoracy is conscious familiarity with technology, the operational aspects of which are, in most cases, inaccessible to the common person. But the basic ideas behind technological tools, their potential and the dangers they entail, the moral principles underlying the use of technology are essential issues to be spread among children from an early age. History shows us that ethics and moral values are closely linked to technological progress. The three preceding aspects together constitute what is essential for being a citizen in a world that is rapidly moving towards a planetary civilization. “

4. ROCK MATHEMATICS

My favorite, ça va sans dire …
I discovered some great information!
Of course, mathematics in this light is completely different!
Above all, I would mention Kate Bush

the lyrics of this song really include the Pi π up to the 78th decimal and then from the 101st to the 137th albeit with a slight difference.
You can listen to her own voice explaining the reason during an interview with the BBC.

I really like the challenge of singing numbers, as opposed to words because numbers are so unemotional as a lyric to sing and it was really fascinating singing that. Trying to sort of, put an emotional element into singing about…a seven…you know and you really care about that nine. I find numbers fascinating, the idea that nearly everything can be broken down into numbers, it is a fascinating thing; and i think also that we are completely surrounded by numbers now, in a way that we weren’t you know even 20, 30 years ago we’re all walking around with mobile phones and numbers on our foreheads almost; and it’s like you know computers…
I suppose, um, I find it fascinating that there are people who actually spend their lives trying to formulate pi; so the idea of this number, that, in a way is possibly something that will go on to infinity and yet people are trying to pin it down and put their mark on and make it theirs in a way I guess also i think you know you get a bit a lot of connection with mathematism and music because of patterns and shapes…

But obviously the book talks about much, much more starting from a large study on the Beatles to get to Queen, Led Zeppelin, Radiohead, Genesis, Coldplay… well… #stylerock

Paolo Alessandrini has a blog and a youtube channel, listen to this reading of an excerpt to understand how from mathematics we go to rock to get to concepts such as self-referentiality, art, Escher

A fascinating and interesting all-round journey that can only focus on poetry or cinema as well.

There is therefore also mention of A Dream within a Dream by Edgar Allan Poe

All that we see or seem
is but a dream within a dream

these verses, together with a passage from Marginalia were read by Orson Welles for Alan Parson’s Project: Tales of mystery and imagination, which, as often happens with the true genius, was only able to materialize later, but that’s another story.

and finally
SEVEN SHORT PHYSICS LESSONS

“What place do we, human beings who perceive, decide, laugh and cry, in this great fresco of the world offered by contemporary physics? If the world is teeming with ephemeral quanta of space and elementary particles, what are we? We are also made only of quantum and particles? But then where does that feeling of existing individually and in the first person that each of us feel? So what are our values, our dreams, our emotions, our own knowledge? What are we, in this boundless and glowing world? “

Carlo Rovelli asks a rather difficult question.
Do you want to try to answer yourself?

INTERNATIONAL COFFEE DAY

INTERNATIONAL COFFEE DAY

Every year on October 1st, the international day is intended to celebrate coffee and recognize the millions of people around the world: farmers, roasters, baristas, coffeehouse owners and more, who work hard to create and serve the drink we love.

International Coffee Organization dedicates the focus of the 2020 edition to a collective mission to help coffee farmers around the world to receive a fair and viable income with the program Coffee’s next generation to specifically support the next generation of young producers.

Catarina explains it better:

In case you are interested, here is a small summary of some scheduled events:

Starbucks Reserve Roastery Milan offers a coffee tasting of the “Anniversary Blend” but pay attention to the specific time slots: from 9 a.m. to 9.30, from 11 a.m. to 11.30, from 2 p.m. to 2.30 and from 4 p.m. to 4.30, excluding the Malpensa Terminal 1 and Cordusio premises.

Talent Garden Calabiana organizes an outdoor community breakfast sponsored by Lavazza.

Cimbali  will host the first live broadcast of the Italian Coffee Network full of interviews, demonstrations and webinars in collaboration with the trainers of the Mumac Academy, organized by Istituto Espresso Italiano, SCA Italy and Consorzio di Tutela del Caffé Espresso

On the other hand, at Caffé Gambrinus, the From the bean to the cup event has unfortunately been canceled.
Just as on the Milano Caffè website nothing appears.
And it is a real shame because never before would it be appropriate to encourage the cafes that have been particularly affected.

For this reason I find the initiative of La Genovese Caffé nice: Offer a coffee to your bartender which proposes to overturn the roles leaving for once a suspended coffee for the one who prepares it, in order to express closeness and sympathy.

Or more simply as indicated here
On October 1st, World Coffee Day, users are invited to take a photo or screenshot of their coffee date and post it and tag @juliusmeinlofficial to support a global cause.
For each contribution that uses the @juliusmeinlofficial tag during the campaign period, be it a comment, post or story, Julius Meinl will contribute € 1 (or the equivalent in USD) in support of Worldreader up to a total of 11,534 $ (Eleven Thousand Five One hundred and thirty-four US dollars).

Another BEAUTIFUL THING is: Meet with a poem!

Among other things, speaking of poems, I could tag important friends.

The explanation of the initiative appears on the website: Julius Meinl who is the organizer and foresees a poem to be written together with a dear friend to receive two special coffees in exchange.

But ours are always special coffees, right !?
