David Attenborough hit the headlines yet again in 15 May 2009 with an opinion piece in New Scientist. This is a quotation:

 

‘He has become a patron of the Optimum Population Trust, a think tank on population growth and environment with a scary website showing the global population as it grows. "For the past 20 years I've never had any doubt that the source of the Earth's ills is overpopulation. I can't go on saying this sort of thing and then fail to put my head above the parapet."

 

There are nearly three times as many people on the planet as when Attenborough started making television programmes in the 1950s - a fact that has convinced him that if we don't find a solution to our population problems, nature will:
"Other horrible factors will come along and fix it, like mass starvation."

 

Bob Hawke said something similar on the program Elders with Andrew Denton:

 

 

 

Climate

 

I originally wrote the paper, Issues Arising from the Greenhouse Hypothesis, in 1990 and do not see a need to revise it substantially.  Some of the science is better defined and there have been some minor changes in some of the projections; but otherwise little has changed.

In the Introduction to the 2006 update to that paper I wrote:

Climate change has wide ranging implications...  ranging from its impacts on agriculture (through drought, floods, water availability, land degradation and carbon credits) mining (by limiting markets for coal and minerals processing) manufacturing and transport (through energy costs) to property damage resulting from storms.

The issues are complex, ranging from disputes about the impact of human activities on global warming, to arguments about what should be done and the consequences of the various actions proposed.

Travel

Istanbul

 

 

Or coming down to earth...

 

When I was a boy, Turkey was mysterious and exotic place to me. They were not Christians there; they ate strange food; and wore strange clothes. There was something called a ‘bazaar’ where white women were kidnapped and sold into white slavery. Bob Hope and Bing Crosby, or was it Errol Flynn, got into all sorts of trouble there with blood thirsty men with curved swords. There was a song on the radio that reminded me over and over again that ‘It’s Istanbul not Constantinople Now’, sung by The Four Lads, possibly the first ‘boy band’.

The First Man on the Moon

 

 

 

 

At 12.56 pm on 21 July 1969 Australian Eastern Standard Time (AEST) Neil Armstrong became the first man to step down onto the Moon.  I was at work that day but it was lunchtime.  Workplaces did not generally run to television sets and I initially saw it in 'real time' in a shop window in the city.  

Later that evening I would watch a full replay at my parents' home.  They had a 'big' 26" TV - black and white of course.  I had a new job in Sydney having just abandoned Canberra to get married later that year.  My future in-laws, being of a more academic bent, did not have TV that was still regarded by many as mindless.

Given the early failures, and a few deaths, the decision to televise the event in 'real time' to the international public was taking a risk.  But the whole space program was controversial in the US and sceptics needed to be persuaded.

In Australia we knew it was really happening because Tidbinbilla was tracking the space craft, as it had previous Apollo launches, and the Parkes radio Telescope had been requisitioned to receive the live television signal, so that an estimated 600 million viewers could watch it too.  Nevertheless for a wide range of reasons, ranging from religious orthodoxy and anti-scientific scepticism to dislike of the Kennedys and big government in general, conspiracy theorists in the US and elsewhere continued to claim that it had been faked for decades later.

The immediate media reaction to Armstrong's: 'one small step for man one giant leap for mankind', statement was a bit unforgiving.  In the heat of the moment, with his heart rate racing; literally stepping into the unknown; Armstrong had fumbled his lines.  He should have said: 'a man'.

As it was the recording, that will now last, as of a seminal moment in history, into the unforeseeable future, is redundant and makes no sense - an added proof, if one were needed, that it wasn't pre-recorded or faked.

I've talked about Kennedy's motivation for the project elsewhere on this website [Read more...] but the outcomes for the entire world turned out to be totally unpredictable and massive.  Initially engineering in the US had not been up to the task and the space program stumbled from one disaster to the next, with the Russians clearly in advance, but now some centralised discipline needed to be imposed - to herd the cats.  Simply using a single standard of weights and measures was a challenge. 

Yet the incredible challenges involved required new technology and an open cheque had been committed.  Billions of dollars funded tens of thousands of research projects that led to many thousands of innovations.  New materials and methods of manufacture were developed.  Perhaps the most important were semiconductor electronics at companies like Fairchild and Bell Labs and computer science at the previously mechanical card sorting and calculating companies: NCR and IBM that had once been sceptical of this newfangled electronic stuff.  Engineering and science educators expanded to provide the young researchers, engineers and programmers.

Unlike the wartime 'Manhattan Project' much of the research was published. Scientific American was required reading among my friends. In any case the speed of innovation rendered advances redundant in a matter of months. Thus quite a bit of this taxpayer funded technology 'fell off the back of the truck' and computer engineering entrepreneurs like Hewlett Packard, who had got their start making sound equipment for Walt Disney, quickly took advantage, soon to be joined by many others. So that today electronics and communications related industry has become the core of the US economy.

Today the computing and communications technology you are using to read this is several millions of times more powerful than that employed to put Neil Armstrong on the Moon and this is indeed a testament to that 'giant leap' that, in part, enabled 'one small step for (a) man' 50 years ago.

The Meaning of Life

 

 

This essay is most of all about understanding; what we can know and what we think we do know. It is an outline originally written for my children and I have tried to avoid jargon or to assume the reader's in-depth familiarity with any of the subjects I touch on. I began it in 1997 when my youngest was still a small child and parts are still written in language I used with her then. I hope this makes it clear and easy to understand for my children and anyone else.
