How many degrees of separation?

It was in the late 1960s that the psychologist, Stanley Milgram, ran his small experiment to determine how many steps it would take for 160 people living in Omaha, Nebraska to use their social acquaintances to direct a mail package to a stockbroker located in Boston, Massachusetts. On average, he found the exercise took five to six stages of social contacts to eventually result in the mail packages arriving to the stockbroker. This result led to the concept of six degrees of separation.

In an interconnnected world, now dominated by convergent technology in telecommunications and the internet, the six degrees of separation paradigm would appear to be shifting to a series of cross connections which may mean in many respects that six degrees may often be much less.

In a simple example of this new interconnected reality, I placed a simple quiz on one of the latest social networking sites, Facebook and uploaded it to the main directory of the site. The number of quizzes on Facebook runs into the hundreds and so this item could be easily lost. Without any marketing or promotion, just interconnected communities of people, over 42,000 persons undertook the quiz online spread throughout a dozen different countries over two weeks. All of this was effectively electronic word of mouth and social networking.

Eye into space

Later this month the European Space Agency will launch the Herschel Space Observatory (formerly called Far Infrared and Sub-millimetre Telescope or FIRST) into remote orbit 1.5 million kilometres from Earth (or four times the distance to the moon). The telescope has the largest single mirror ever built for a space telescope. At 3.5-metres in diameter the mirror will collect long-wavelength radiation from some of the coldest and most distant objects in the Universe. In addition, Herschel will be the only space observatory to cover a spectral range from the far infrared to sub-millimetre.

Herschel is only the latest in a list of similar heat sensing telescopes placed in orbit outside of Earth the others being IRAS (1983), ISO (1995-98), Spitzer (2003-09), Akari (2006-2007).

While admiring these efforts to boldly go where no-one has gone before, its almost axoimatic that the large funds spent on space exploration would equally be valuable being focussed on the declining environmental situation back on planet Earth. Its almost ironic that as science explores the outer reaches of space and the formation of the universe, our own home planet is heading for an atmospheric decline which may render much of this exploration as redundant.

How much money is needed?

The G20 summit in London concluded this week and the leaders of the member countries have committed to $1.1 trillion in new funds which will greatly increase the capital available to the International Monetary Fund. The goal in mind is a revival in trade, which is expected to contract this year for the first time in 30 years. Of note however the combination of loans and guarantees fell short of an injection of fresh fiscal stimuli into the world economic system — this was due to division between Continental Europe and the United States over whether to act now or wait to see whether existing spending measures took effect.

Most member countries have already committed major funding outlays and released vast sums of funds into their economies through various mechanisms - in the US this has meant buying up the bad debts and loans which their banking system had both created and then shared with the world. In Australia, the strategy is to stimulate consumer spending by providing actual cash payments to families earning under $100K per annum. The question is whether these levels of payments are sufficient to compensate for the loss of economic activity due to the mismanagement in part of the world (and US in particular) banking system. Will it be enough?
