Physics Always Follows the Rules

 

RMS Titanic has fascinated people for well over a century now, its construction, technology, launch, passengers, and sinking the subject of thousands of books, movies, and television specials churning up the same old factoids over and over. The reality is that there is probably nothing about Titanic that we don’t know despite tabloid-ish advertisements promoting solved and unsolved mysteries, purported riddles, discoveries that aren’t really discoveries, and even ghosts and curses.

 

As a tee-shirt said during all the giddiness about the Jack and Rose film, “The Ship Sank; Get Over It.”

 

But the continuing fascination is understandable. In a time when most people did not have electricity or running water the Titanic might have seemed as high-tech to them as the science-fiction Enterprise does now. The famous and wealthy passengers, the jewels, servants, and strictly observed class divisions are the sorts of things we decry while watching Upstairs, Downstairs, Downton Abbey, and Sanditon. In this manifestation of the “ship of fools” theme Titanic features the best and worst of technology, human nature, and Edwardian décor.

 

There is no evidence that Captain Smith or anyone else said, “Madam, God Himself couldn’t sink this ship,” but as demonstrated in the tabloids, television, and now the InterGossip humans seldom allow reality to interfere with fantasy.

 

The nature of hubris and the minutiae of ignored lifeboat drills and careless seamanship have been discussed to the point of obsessiveness, but the disaster occurred because of one inexplicable error in judgement: the captain was driving too fast at night without headlights.

 

Recently, forced comparisons between Titanic and the recent loss of what appears to be an imaginatively but maybe inadequately designed submersible occupied our Orwellian telescreens for a week, and I confess that I followed events closely.

 

I was aware that those whose pockets are loaded with the green stuff could take tourist visits to the wreckage of Titanic but paid little attention to it. Like most people I generally assumed that planes, trains, ferryboats, ships, underground railways, trolleys, busses, and other forms of public transportation are regulated by the appropriate government agencies and thus safe for the general public.

 

However, in following the frequent and almost breathless bulletins we learned that the Titan (clever name, eh?) appears not to have been inspected by or registered with any responsible board or agency. 

 

“I think it was General MacArthur who said you’re remembered for the rules…And I’ve broken some rules to make this. I think I’ve broken them with logic and good engineering behind me.”

The many reported flaw designs of Titan have been discussed at length, but ultimately there is this: except for the 19-year-old, the four other crew / passengers / “mission specialists” / tourists were middle-aged men of great accomplishments in science and business, and thus brilliant in solving problems. Why did they not see a problem in crowding themselves and a teenager into a large pipe, bolted and sealed from the outside, from which there was no possible escape?

 

In most of the possible failure scenarios escape was a null concept anyway – you can’t escape a vessel at however-many-thousands of feet down. But even if the Titan had remained intact and surfaced the only way out was for the technicians on the mother ship to locate the submersible, board it or retrieve it, and then free the many bolts. But what if the mother ship weren’t there? What if it caught fire and sank? What if a Gilligan dropped into the ocean the one specialty wrench needed?

 

Physics is an absolute judge, and will not accept any special pleadings from those who don’t follow its rules.
