You probably know what a crystal is. We’ve all seen one, held one in our hands, and even tasted one on our tongue (for instance sodium chloride crystals, also known as “salt”). But what on earth is a “time crystal”, if not a sci-fi gadget in the latest Marvel movie? Why do we need a quantum computer to make one? And what is aquantum computer anyway? Bits and qubits Let’s start there. Computers are all around us. Some are compact, portable, and primarily used to stream Netflix, while others fill entire rooms and simulate complex phenomena like the weather or…

Deep neural networks have a huge advantage: They replace “feature engineering”—a difficult and arduous part of the classic machine learning cycle—with an end-to-end process that automatically learns to extract features. However, finding the right deep learning architecture for your application can be challenging. There are numerous ways you can structure and configure a neural network, using different layer types and sizes, activation functions, and operations. Each architecture has its strengths and weaknesses. And depending on the application and environment in which you want to deploy your neural networks, you might have special requirements, such as memory and computational constraints. The…

On Feb. 4, 2022, SpaceX launched 49 satellites as part of Elon Musk’s Starlink internet project, most of which burned up in the atmosphere days later. The cause of this more than US$50 million failure was a geomagnetic storm caused by the Sun. Geomagnetic storms occur when space weather hits and interacts with the Earth. Space weather is caused by fluctuations within the Sun that blast electrons, protons and other particles into space. I study the hazards space weather poses to space-based assets and how scientists can improve the models and prediction of space weather to protect against these hazards.…
