We know the story: one hundred years ago, this Sunday, the 882-foot Titanic, then the largest ship afloat, side swiped an iceberg and sank on her maiden voyage. Almost three-quarters of her 2,224 passengers drowned in the freezing North Atlantic.

How could a ship so large, so technologically advanced, so “practically unsinkable” have sunk on her maiden crossing? Well, we know how. Five of her 16 watertight compartments flooded, one more than the maximum number she could have withstood. James Cameron shows exactly how he thinks she went down in the CGI piece, above.

And what of the why? Even today new theories emerge. The New York Times reported last month that, according to new research, 1000-year high tides in the winter of 1911–12 sent an enormous number of icebergs into North Atlantic shipping lanes, and that cold-water mirages obscured icebergs from the Titanic’s lookouts and the Titanic herself from potential rescuers.

Not only did her owners’ hubristic faith in her invincibility conspire against the Titanic and her passengers that night, it now appears that so too did nature itself.

It’s a lesson I hope won’t be lost on us as we consider our invincibility in our own time.
