 The weak force is much weaker than electromagnetism at typical distances within an atomic nucleus (but is still stronger than gravity), and has a short range, so has very little effect as a ''force''. What it has instead is the property of changing one particle into another. It can cause a down quark to become an up quark, and in the process release a high-energy electron and electron anti-neutrino. This is known as {{w|beta decay}}, a form of radioactivity. Over even shorter distances, {{w|electroweak theory|and much higher temperatures}}, the weak interaction and electromagnetism are essentially the same, thus being merged to form the {{w|electroweak force}}. The electroweak force was also mentioned in a later comic, [[1956: Unification]].
-The title text refers to the fact that it is gravity that appears to be the simplest and easiest to understand of the four forces, but turns out to be the {{w|Quantum_gravity|hardest to reconcile}} with a coherent (quantum) understanding of {{w|Theory of everything|all four forces together}}.
+The title text touches upon a strange paradox regarding gravity: in isolation it is the simplest and easiest to understand of the four forces, with well-understood equations that can be taught to the layman with clear-cut examples (as it is the one force everyone experiences on a regular basis). However when taking other forces into account gravity turns out to be the {{w|Quantum_gravity|hardest to reconcile}} with a coherent (quantum) understanding of {{w|Theory of everything|all four forces together}}.
