5 Killer Strategies for Studying Physics

Author: Max Wilbert Physics has a tough reputation. It’s less memorization-based than many other technical subjects, and requires critical thinking to link concepts into a unified vision. To succeed in physics, you’ll need some effective study strategies. Here at Brainscape, we’ve got a few tips to share. These are based on the experience our team has […]

THE OXYGEN ILLUSION

One of the most common questions about the Universe is “Do aliens exist?” The answer is: we don’t know. However, in the last 25 years almost 2000 planets have been discovered orbiting distant stars. This has brought us much closer to an answer. These distant worlds are called exo-planets. They are all so far away […]
