What the physics? How to eat pizza, how rainbows are made, and more
At the bottom of every great scientific discovery is a question. Often, the simpler the question, the more fascinating the answer.
How are stars made? Why is the sky blue? If stuff is made of molecules, and molecules are made of atoms, and atoms are made of protons and electrons, then what are protons and electrons made of?
It’s these big, juicy questions that keep scientists going. We’ve worked out the answers for some, but others are still out there. And the best thing is, an answer usually leads to a new question.
For now, feed your curiosity and impress your friends with these fascinating factoids.

About PI
Perimeter Institute is the world’s largest research hub devoted to theoretical physics. The independent Institute was founded in 1999 to foster breakthroughs in the fundamental understanding of our universe, from the smallest particles to the entire cosmos. Research at Perimeter is motivated by the understanding that fundamental science advances human knowledge and catalyzes innovation, and that today’s theoretical physics is tomorrow’s technology. Located in the Region of Waterloo, the not-for-profit Institute is a unique public-private endeavour, including the Governments of Ontario and Canada, that enables cutting-edge research, trains the next generation of scientific pioneers, and shares the power of physics through award-winning educational outreach and public engagement.
