Communicating Science

• You can’t not communicate (1st law of communication).  But at the same time, communicating efficiently is an ability that needs to be learned and constantly improved.  This is always a must, but most of all in the field of science, where convincing the public (and investors) of the importance of your research is becoming everyday more important.This didactic module is an introduction to communication for future researchers, engineers, technicians and any other profession related to science.  We do not intend to train professional communicators but to provide to a PhD student some communicating skills he will need sooner or later in his future work, like talking to an audience, presenting the results of his work to an investor, collaborating with press offices, managing interviews by journalists, writing articles for different media, making a website to spread his results, organizing fund raising activities.
• The module is based on hands-on activities and laboratories , starting from the analysis of science communication Case Studies that will be presented and discussed in italian and/or in english (depending on the content) .

Dynamics of Soft Gels

Polymer gels are very soft elastic materials, and their striking feature of is the capability of exploiting chemical energy to produce mechanical work. 
From the physical point of view, gels are elastic materials swollen by a fluid: their elastic properties are inherited from the polymer network, while their swelling 
properties are related to the migration of the solvent through the network. 
 
Following the pioneering work of J.P. Flory, Nobel prize 1974, we shall present the statistical origin of the free energy for polymer mixtures.
 
Then, basing on the mechano-chemical model of Flory-Rehner energy, we shall 
develop the modern model of stress diffusion, with emphasis on time evolutive processes.

Python Basics

Python Basics consists in a series of 8 lessons hosted at Dipartimento di Matematica  e Fisica - Università degli Studi Roma TRE. 
The seminars will cover the fundamentals of Python, starting from the basics. A relevant of part of the seminars will be devoted to hands-on exercises, which we strongly recommend to the attendees. No prior knowledge of Python is required.  

Starting from really basic notions, the students will get acquainted with the standard programming techniques used in Python;
moreover, to test the competences acquired by the students,  the last 2 lessons will be devoted to the implementation of an actual problem that subsumes most of what has been explained during the lessons.

A certificate of attendance will be issued to all participants.
