This doesn't really have anything to do with online learning, but it's a finding worthy of note: "in early 2022, strong enough electric fields were created in a simple laboratory setup leveraging the unique properties of graphene, enabling the spontaneous creation of particle-antiparticle pairs from nothing at all." This not only illustrates that quantum physics is changing our understanding of the world, it also shows that graphene has some remarkable properties. I still think the future of technology is carbon, carbon and carbon. The image is from the article, but I found a much better quality version via ScienceBlogs.
