# Math Is In The Air January 2017 Column

By on 05/02/2017

Hello again by Math Is In The Air. This is our review of posts written in January 2017. Before them, just a brief introduction for thos who don’t know us.

Math Is In The Air (MIITA) is an italian project started at the beginning of 2015 as a blog on Applied Mathematics. It had just a few collaborators and a bunch of posts. The italian website, at the moment, has 20 collaborators and more than 130 published posts on advanced applied Mathematics. At the beginning of 2016 we started our english blog and we are trying to expand it.

In this column we would like to present the posts we published in January 2017 in the italian blog. I will try to give you an idea of the content and I will redirect to the original post. Are you ready?

#### 1) 07/01/2017: Special proof of the Pythagorean theoremby Raffaele Quatraro

The original name of the post is “Particolare dimostrazione del Teorema di Pitagora“.

The aim of the post is to deepen the three concepts of generalization, specialization and analogy. And the main character of the story is obviously the Pythagorean theorem. It is a very interesting post.

#### 2) 11/01/2017: Mathematics and Credit risk (part 3)by external contributor Giovanni Conti

The original name of the post is “Matematica e Rischio di credito (parte 3)“.

This is the third part of a series written by the external contributor Giovanni Conti. The series is about mathematics applied into Credit risk problems. In the website you can also find parts 1 and 2.

#### 3) 16/01/2017: Trigonometry, beats and musical tuningby Enrico Degiuli

The original name of the post is “Trigonometria, battimenti e accordatura strumenti“.

The aim of the post is to show the magic application that mathematics has in music. The connection between these two subjects is amazingly explained by Enrico that applies trigonometry to the study of beats and tuning.

#### 4) 22/01/2017: Automatic learning for recognition of malaria’s mosquitosby external contributor Davide Zilli

The original name of the post is “L’apprendimento automatico per il riconoscimento delle zanzare malariche“.

This is a post by Davide Zilli, an external contributor. The aim of his post is to show the connection between the real problem of recognize mosquitos responsible of malaria and the mathematical branch of Machine Learning. An unforgettable post.

#### 5) 25/01/2017: MAThouse – new humor section in MIITAby Andrea Capozio

The original name of the post is “MATEcomio – La nuova sezione Humor di MIITA“.

This post is a collection of jokes about mathematics. Just to have fun!

#### 6) 30/01/2017: How were numbers born: formalization of number sets and infinitesimal calculusby Pierandrea Vergallo and Alessandro Carbotti

The original name of the post is “Come nascono i numeri: la formalizzazione degli insiemi numeri e il calcolo infinitesimale”.

The post is the story of how numbers have been “invented” and a bit of history of them. Read it, it’s worth it!
