Nares Ice Bridge Breakup

The ice bridge in Nares Strait at the Kane Basin outlet to Baffin Bay has begun to break up.

There was a plug of consolidated ice solidly wedged across the channel.  Consolidated ice is very strong in compression, but weak in tension, as I have noted in other articles, such as Bridges That Build Themselves.  From that article:

“Auntie”, better known as the BBC, has just treated us to a two-parter, Everything and Nothing, by Jim Al-Khalili.  He thoroughly knows his history of science, rather than treating it as an add-on, and delivers the significance of what he says without spoiling it through philosophy and vain deceit” [1].

The blurb says:

Why should technology not go on and accelerate like it has before? Why should humanoids not get ever brighter; why should democracy not grow until true communism emerges? Techno-progressives emanate an air of renegade radicalism. They like to accuse critics of not thinking things through sufficiently and stopping at the point best befit to rationalize beliefs.

Yet both, the critics and many proponents of technological enhancement alike agree on where to stop asking: a racist ‘we (I, humans, our planet) must survive and conquer’ plus lip-service toward a pseudo-democratic doctrine so comfortably ‘coincidentally’ at the helm as we speak. As bad as that may be regarding other issues, it turns into Jules Verne stories when discussing future.

Scientists are often portrayed as serious yet quirky, but many hide a prankish interior.  Here's a butcher's dozen of famous pranks by -- or at-- scientists.

The best lecture never heard.

Have you noticed that whenever a [natural]disaster strikes we quickly look around to find a guilty party? The first place we look is among politicians. The politicians are not to blame for the natural disaster of course, at least not the nature part of it. The dimensions of the disaster can however fairly easily be tracked back to humans, more specifically to the political leadership who are responsible for managing both natural and human resources.
