The March for Science

By | ABC, Climate Change, Education, History, Media, Politics, Religion, Research | 106 Comments

I am writing this essay on the day of the March, which will happen in Washington DC and apparently 500 other cities, including several in Australia, where the March is happening as I write. What is it about? There is apparently a ‘war on science’, though who is conducting it is not clear. From its US website you can get this mission statement. The March for Science champions robustly funded and publicly communicated science as a pillar of human freedom and prosperity. We unite as a diverse, nonpartisan group to call for science that upholds the common good and for political leaders…

Ending ‘the violence of prostitution’

By | Health, History, Media, Politics, Society | 18 Comments

A young woman (I’ve seen her photo) called Andrea Tokaji had a piece in one of our local newspapers, which I read quickly and then read more slowly and carefully. She is ‘a PhD candidate on gender-based violence’ and the Founding Director of Fighting for Justice Foundation. It’s an interesting website, and is largely about bringing and end to ‘human trafficking’, which includes sexual slavery, forced marriage, organ removal and forced labour. The International Labour Organization puts the current numbers at about 21 million, about two thirds in forced labour and a quarter in sexual exploitation of one kind or another. In…

What is it that worries me about what the BoM and CSIRO tell us about climate change?

By | ABC, Climate Change, Environment, History, Media, Politics, Religion, Research | 262 Comments

Commenter Chris asked me, in a comment at my last essay, what are your concerns over BoM reporting or data use? I had intended to write about something else, but it seemed sensible to deal with this issue at once. I have written about the Bureau before (here, for example, and here), but to this direct question there is a straightforward reply. I’ll deal first with the more general issue of BoM (Bureau of Meteorology) reporting, and note first that it is directly linked, as anyone who reads the website will see, with CSIRO’s biennnial reports on the State of Climate. So my response to Chris covers both…

Mathematics, my father and me

By | ABC, Books, Education, History, Politics, Society | 47 Comments

(Robyn Williams, of the ABC’s Science program, read my piece in Quadrant about how my own world-view came to be formed, and asked could I do an Ockham’s razor broadcast about my father, mathematics and me. This is the outcome. It was broadcast on Sunday March 12th and interested readers can download the audio  here.)   If you grew up in New South Wales in the 1940s, 50s and 60s, there’s a good chance that you studied maths with the help of the textbooks written by two high school teachers, A. G. Aitkin and B. N. Farlow. I knew the…

Books that have been important to me #4 Barbara and Allan Pease: Why Men Don’t Listen and Women Can’t Read Maps

By | ABC, Books, Education, Health, History, Humour, Media, Society | 160 Comments

In 1998, my wife and I were driving through northern New South Wales, and had the radio on. Margaret Throsby introduced her guest, Allan Pease, told us the name of his new book, and said something like, ‘Now I want to take issue with you at once about the title. I can read a map as well as any man!’ ‘How do you do it?’ he asked. ‘Well, I point it in the direction we are travelling and it’s straightforward.’ ‘That’s exactly the point of the title,’ he responded. ‘Most men can read a map however it is pointed, but most…

A final thought on 2016 Australian warming

By | ABC, Climate Change, Environment, History, Media, Politics, Religion, Research | 232 Comments

In an earlier essay this year, I used the useful maps prepared by Professor Ole Humlum of www.climate4you to ponder about how hot it actually was in Australia last year. I did so because of claims that the year was the hottest ever, as it was said to be for the world. When I wrote the piece I did not have access to the summary for the whole year, but I now have it, and it is displayed below. These data are from the Goddard Institute of Space Studies, which is part of NASA, and they show the relative change between…

Mr Abbott as class bad boy

By | Climate Change, Economy, Education, Environment, Health, History, Language, Media, Politics, Society | 154 Comments

Mr Abbott launched a book the other day, and the speech, which you can read here, instantly led to what I now think has been a media beat-up. His short address has become a further indication, for some in the media, and of course for the Labor Party, of the growing destabilising of the Government and the fragility of the Prime Minister. In fact, I think that Mr Abbott’s speech and its content deserve much closer reading. I should probably qualify what follows by saying that I do not agree with some of what Mr Abbott says, but he is absolutely right in reminding…

Where is the money to come from?

By | Books, Education, Health, History, Politics, Society | 86 Comments

Last week I went to Parliament for the launch of a major study called the Economic Cost of Dementia in Australia. It was commissioned by Alzheimer’s Australia, and carried out by NATSEM, the social and economic modelling group at the University of Canberra. Their work is always accurate and thoughtful, and the presentation was excellent. Since I have a couple of roles with Alzheimer’s, and am also a carer, I had an immediate interest in what was being put forward to us. I’ve read the report and have no major criticisms. I am always a bit suspicious of talk about ‘economic costs’, for example…

Exit right, Cory Bernardi

By | ABC, Books, Climate Change, Economy, Environment, History, Humour, Media, Politics, Society | 165 Comments

I have not met Senator Bernardi, but I’ve read  some of his writing. From what I have read in the media and on line, it might surprise some people to learn that in fact he is a published author. His seven books include two for children, the rest being about politics, collections of his own opinion pieces, and a book that did well in the review sections, The Conservative Revolution. Thus far the talk has all been about how his defection from the Liberal Party is another destabilising factor for Prime Minister Malcolm Turnbull. Since Bernardi is unlikely to vote for anything…
