Cern’s Large Hadron Collider: not as big as I thought

A friend tonight sent me a link to some ludicrous rap about the Cern laboratory on the Franco-Swiss laboratory. At 27km in circumference, its Large Hadron Collider is impressive, but its oft-quoted dimension makes it seem bigger than it actually is.

It’s 4.3km in radius, or 8.6km in diameter. Put another way, it’s like a circle centred at Elephant and Castle, stretching to Clapham in the south-west, Knightsbridge (W), Great Portland Street (NW), Islington (N), Stepney (NE), Rotherhithe (E), Nunhead (SE), and a little north of Herne Hill (S). It’s 20% greater in length than London Underground’s Circle Line.

Big, but not quite as ludicrously big as I’d previously thought.
