Coloquio de Física – Cien años de una nueva visión del espacio-tiempo: la relatividad general de Einstein

Ponente: Francisco De Zela (Sección Física PUCP) La conferencia ha sido motivada por cumplirse cien años de la publicación de la relatividad general. Tendrá un carácter introductorio, tratando de situar el aporte de Einstein en el contexto de épocas pasadas, así como de la actual. Dicho aporte trasciende el ámbito de teorías gravitatorias, proyectándose a una buena parte de la física teórica.

To Infinity and Beyond: The Accelerating Universe

Published on Jul 15, 2015

Dark energy is cosmology’s biggest mystery—an anti-gravitational force that confounds the conventional laws of physics. It makes up more than two-thirds of the cosmos, but science is still grappling to explain what dark energy actually is. In this program, top physicists search for clues to this mystery in both the earliest moments of the universe and far into the future of the cosmos.

The accelerating Universe: Nobel Laureate Brian Schmidt

Published on Aug 2, 2012

In 1998 two teams traced back the expansion of the universe over billions of years and discovered that it was accelerating. It was a startling discovery that suggests that more than 70 per cent of the cosmos is contained in a previously unknown form of matter, called Dark Energy.

En 1998, dos equipos rastrearon la expansión del universo durante miles de millones de años y descubrieron que se estaba acelerando. Fue un descubrimiento sorprendente que sugiere que más del 70 por ciento del cosmos está contenido en una forma hasta ahora desconocida de materia, llamada energía oscura.

Talks @ Google Presents Kara Miller and Eric Mazur

Streamed live on Nov 14, 2014

Radio show host Kara Miller from WGBH’s Innovation Hub interviews physicist Eric Mazur, Harvard’s internationally recognized educational innovator and advocate of Peer Instruction. With tuition and student debt rising, what if a college education isn’t worth it? We’ll talk about why too little learning goes on in college classrooms – and how to change that.

Kerstin Persson Waye: A caring sound environment in hospitals?

 

 

A caring sound environment in hospitals?

Video from Care for Sound Symposium, in collaboration with the Sound Environment Centre at Lund’s University. The symposium focused on the impact of noise in the healthcare sector, and possible solutions to what is widely considered as one of the main challenges for a healthy healthcare environment.

Hospitals should be conducive to patient recovery and safety as well as employee health and productivity. Medical advances and technical developments contribute to this goal while a supportive acoustic environment hitherto has been largely neglected. The talk will point to critical research results giving a base for future improvements.
