When Worlds Collide: The Family and the Law by Jo Delahunty QC (Gresham College)

# playlist: click the video's upper-left icon

source: GreshamCollege 2016年11月30日
Professor Jo Delahunty QC offers an inside perspective of the family justice system and discusses some of the issues family courtrooms deal with http://www.gresham.ac.uk/lectures-and...
Think of family and what comes to mind? At best, a family united by children, love, partnership; At worst: the death of love, divorce, parents feuding over money and children. But what of the situation where the dispute is not between partners but The State and The Family? A child may be removed because professionals fear that they may suffer, no longer protected by parents but at risk from them.
The transcript and downloadable versions of the lecture are available from the Gresham College website: http://www.gresham.ac.uk/lectures-and...
Gresham College has been giving free public lectures since 1597. This tradition continues today with all of our five or so public lectures a week being made available for free download from our website. There are currently over 2,000 lectures free to access or download from the website.

Chris Budd - Mathematics and the Making of the Modern and Future World

The contribution of mathematicians over the centuries will be celebrated, showing how mathematical ideas have huge relevance today varying between Maxwell and the mobile phone, Florence Nightingale and modern statistics, Pythagoras and the development of music, Euclid and art, Euler and Facebook, and Cayley and Google. http://www.gresham.ac.uk/lectures-and...
Mathematics has played a vital role in the development of human civilisation, and is the foundation of much of modern technology and popular culture. However, the achievements of mathematics and mathematicians are often unknown or misunderstood. Even basic mathematics can make a profound difference to our lives.

UniNettuno - Ingegneria Sanitaria Ambientale / Environmental Health Engineering
Il corso di Ingegneria Sanitaria Ambientale s’inserisce nell’ambito del corso di Laurea in Ingegneria Civile e Ambientale come un esame fondamentale per determinare l’impatto ambientale delle attività umane, riconoscere e classificare le tipologie di inquinamento esistenti e gli impianti atti al trattamento delle acque.
Prerequisiti
Per seguire con profitto il corso occorre conoscere le nozioni apprese nei corsi di Calcolo ed Algebra Lineare, Fisica, Chimica e Scienza dei Materiali, Idraulica e Costruzioni Idrauliche.
Scopi
Al termine del corso lo studente avrà acquisito nozioni riguardanti la teoria alla base dell’inquinamento delle acque, del suolo e dell’aria, oltre ai processi atti alle loro purificazioni e all’ottimizzazione dell’impiego industriale di tali risorse naturali.
Contenuti
Determinazione dell’effetto ambientale delle attività antropiche. Definizione dei parametri dell’inquinamento. Determinazione delle caratteristiche delle acque potabili. Processi ed impianti di purificazione e riciclo delle acque. Ottimizzazione dell’uso dell’acqua in impianti industriali. Riciclo degli scarti industriali.

Please join the Department of Natural Sciences and Mathematics (http://newschool.edu/lang/interdiscip...) and the Ligo Project (http://ligoproject.org/) for a two-day forum that promotes the intersection of the arts, sciences, and policy surrounding emerging technologies and knowledge.
As we more and more readily take into our own hands the future evolution of our bodies, our minds, the civilizations we create, and the very planet we inhabit, it is imperative that we reach across disciplines and across cultures to guide what we do by what we know and guide what we know by what we value.
Over the course of two days, scientists, artists, scholars, organizational leaders, and educators will creatively share ideas about social practice, public engagement, collaboration, and the emergence of new fields at the intersection of arts, science, and culture. Four workshop tracks spanning policy, creative collaboration, laboratory bioart, and improved messaging will take place alongside an exhibit of art-science works, plenary talks, show and tell, collabs, and happy hours.
