Hacking the Nature of Reality
In standard use, the S-matrix can be calculated if you understand the forces in the interaction region - for example, in the nucleus of an atom. But what if you don’t know those internal interaction forces? Heisenberg sought a way to...

Are there Undiscovered Elements Beyond The Periodic Table?
Adamantium, bolognium, dilithium. Element Zero, Kryptonite. Mythril, Netherite, Orichalcum, Unobtanium. We love the idea of fictional elements with miraculous properties that science has yet to discover. But is it really possible that...

What Makes The Strong Force Strong?
Quantum mechanics gets weirder as you go to smaller sizes and higher energies. It’s strange enough for atoms, but positively bizarre when we get to the atomic nucleus. And today we’re going nuclear, as we dive into the weird world of...

Atomic Nucleus
In this video Paul Andersen explains how the structure of the nucleus influences the properties of the atom. The number of the protons determines the kind of element. Isotopes are formed when the number of protons remain the same but the...
