A hotel is the latest flashpoint in a long running conflict in Cabo Delgado, in northern Mozambique.

ISIL-linked fighters besieged the town of Palma, forcing nearly 200 people to seek refuge in a resort.

Many are foreign nationals working on a natural gas project.

The latest assault by the ISIL-linked Al Shabab (not related to the Somali group of the same name) highlights increasing instability in the gas-rich province.

Could the unrest intensify?

Presenter: Mohammed Jamjoom

Fernando Lima - Journalist and political commentator Catholic University of Rio de Janeiro.

When no one is looking, a particle has near limitless potential: it can be nearly anywhere. But measure it, and the particle snaps to one position. How do subatomic objects shed their quantum weirdness? Experts in the field of physics, including David Z. Albert, Sean Carroll, Sheldon Goldstein, Ruediger Schack, and moderator Brian Greene, discuss the history of quantum mechanics, current theories in the field, and possibilities for the future.

This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation.

For all we understand about the universe, 96% of what’s out there still has scientists in the dark. Astronomical observations have established that familiar matter—atoms—accounts for only 4% of the weight of the cosmos. The rest—dark matter and dark energy—is invisible to our telescopes. But what really is this dark stuff? How do we know it’s there? And what does it do? From the formation of galaxies to the farthest reaches of space, it appears that darkness rules. Without dark matter and dark energy, the universe today and in the far future would be a completely different place. We were joined by leading researchers who smash together particles, dive into underground mines, and explore the edges of the known universe in search of clues to nature’s dark side.

Stuff happens. The weather forecast says it’s sunny, but you just got drenched. You got a flu shot—but you’re sick in bed with the flu. Your best friend from Boston met your other best friend from San Francisco. Coincidentally. What are the odds? Risk, probability, chance, coincidence—they play a significant role in the way we make decisions about health, education, relationships, and money. But where does this data come from and what does it really mean? How does the brain find patterns and where can these patterns take us? When should we ditch the data and go with our gut? Join us in a captivating discussion that will demystify the chancy side of life.

The maverick engineer Nikola Tesla made his contribution in the mechanical engineering field too. Look at one of his favorite inventions — a bladeless turbine, or Tesla Turbine. The Tesla turbine had a simple, unique design, yet it was able to beat the efficiency levels of steam turbines at that time. Normal turbines are complex in design, with blades of complicated geometry and stator parts. Nikola Tesla once said the Tesla turbine is his favorite invention and he even claimed an efficiency level of 97% for this turbine. Let’s start a design journey to understand this interesting piece of technology, and towards the end we will also verify Tesla’s efficiency claim.
