# Inside the Perimeter: Spring/Summer 2015

The most dazzling discoveries in science often arise when subjects – or problems – collide. That is the idea behind Convergence, Perimeter’s first alumni reunion, and it’s the focus of the latest issue of the *Inside the Perimeter *magazine.

From turbulent black holes and a new type of crystal to the meshing of art and science – plus a special section devoted to Convergence – here are some of the highlights from the Spring/Summer 2015 issue of* Inside the Perimeter.*

__Science:__

• Perimeter researchers decided to put a piece of science folklore to the test, and surprised themselves with the results: It appears that spacetime *can *be turbulent.

• Dark matter is believed to be everywhere, but how can we actually detect it? Perimeter’s **Maxim Pospelov** suggests using atomic clocks like those in GPS satellites, while **Asimina Arvanitaki **hopes to use black holes to find the proposed QCD axion.

• PI cosmologists** Latham Boyle** and **Kendrick Smith** propose a new kind of crystal – and show how one might be found.

__Arts:__

• Read, and watch, as we dig into the ephemera that sums up **Carlo Rovelli**, co-founder of loop quantum gravity and author of current Italian best-selling book *Seven Brief Lessons in Physics, *with his submission to the art exhibit *Archive Fever*.

• Take a front-row seat for *Quantum: Music at the Frontier of Science*, performed in May at the **National Arts Centre** in Ottawa.

• Check out the year’s **Public Lecture Series **highlights, and then watch the full presentations here.

__Convergence:__

To celebrate **Convergence **– Perimeter’s first alumni reunion – we asked a range of physicists for their take on the state of science today. Find out more about Convergence – and read their answers – here.

__General:__

• PI Kids Ask: How does a spinning egg stand on its pointy end?

• From the Black Hole Bistro: Is hot or cold brew coffee better?
