Perché E=mc²? (e perché dovrebbe interessarci?)

Cox's approach makes advanced ideas feel approachable, but I wonder what inspired the specific explanations and analogies he chose.

I loved learning how the theory developed over time, but I'm curious if others felt it added a new layer of understanding or just slowed the pace.

The casual tone made complex ideas feel less intimidating, but I wonder if this was a deliberate decision to reach a wider audience.
