Science isn't just about solving this or that puzzle. It's about understanding how the world works: the whole world from the vastness of the cosmos to the particularity of an individual human life. It's worth thinking about how all the different ways we have to talk about the world manage to fit together.

A full understanding of what happens in our everyday lives needs to take into account what happened at the Big Bang.

The idea that time is an illusion is an old one, predating any Times Square ball drop or champagne celebrations. It reaches back to the days of Heraclitus and Parmenides, pre-Socratic thinkers who are staples of introductory philosophy courses.

Technology has enabled government to have investigative and situational awareness on a scale and scope that were science fiction when the Stasi shut its doors.

Quantum field theory was originally developed for the treatment of electrodynamics, immediately after the completion of quantum mechanics and the discovery of the Dirac equation.

You can't train kids in a world where adults have no concept of what science literacy is. The adults are gonna squash the creativity that would manifest itself, because they're clueless about what it and why it matters. But science can always benefit from the more brains there are that are thinking about it - but that's true for any field.
