WHAT IS THE SCIENTIFIC METHOD?

October 21, 2020

Science works, so we suppose, because it is more evidence-based, more logical and more objective than other subjects. So much so that nowadays we are all urged to argue in an ‘evidence-based’ manner.

The extraordinary truth though is that nobody knows what ‘The Scientific Method’ is, or how it actually works.

Back in 1997 when my own scientific project sank into a quagmire of ‘Conflicting Evidence’ I felt that the only way to rescue it would be to track down The Scientific Method and apply it to my problem. Easier said than done. Little did I realise that I was embarked on a quest that would last 20 years and range across 25 centuries. The gurus of the business, the Philosophers of Science and the Statisticians, turned out to have little grasp of real Science and were embroiled in squabbles of their own making, having to do with the colour of angels. Indeed they’d so befuddled the subject that no proper scientist would go anywhere near it. Instead scientists carried on, as they always had done, using Common Sense. Unfortunately, from my point of view, none of them seemed willing, or able, to explain just how Common Sense Thinking worked. So I set sail to find out, starting from the suspicion that Common Sense must be a survival mechanism largely inherited from our animal forbears.

Finally (2018) I cracked it . If it seems insane, not to say downright immodest, to claim that one is the first to understand how Common Sense Thinking, and The Scientific Method (much the same), work, I entirely agree. But sometimes the truth dawns first not on the brilliant, but on the first to ask the right question — in this case “How do animals Think?”, because of course they do, otherwise they wouldn’t still be here.

Einstein averred that ; “Science is no more than a refinement of everyday thinking” but admitted “The physicist cannot proceed without a much more difficult problem (than physics), the problem of analysing the nature of everyday thinking.”

If Science stems from Common Sense, and Common Sense is born with us as a vital part of our inherited survival strategy, then why do we need to understand it? Because it must be adapted to a modern world vastly different from the ancient one in which it evolved. To think straight nowadays, and make best use of wonderful modern tools such as search engines and the Internet, we need to become thoroughly familiar with Bayes’ Rule, Ockham’s Razor, the Principle of Animal Wisdom (PAW), Gambling Theory and The Detective’s Equation — almost none of which form part of a contemporary education, even though they could all be picked up by 14-year-olds. Indeed much of modern education actively undermines our capacity to think straight.

If you are interested in thinking as well as it is possible for us humans to do you might want to look at my book Thinking for Ourselves [ Amazon paperback, 2020, 605 pages, £14.50]. The book is described in more detail elsewhere on this site while there is a short and I hope readable resume’ to be read at:

ABOUT MY BOOK ‘THE WHISPERING SKY’

September 29, 2020

A novel about astronomical research

The Whispering Sky is the second of a quartet of self-contained novels relating the saga of two astronomers, originally boyhood friends, caught up in humankind’s endeavour to explore the Universe from Space. Thanks to his feud with Bellfounder – the machiavellian Astronomer-Royal [See ‘Against the Fall of Night’, first in the quartet], Tom Morgan has been thrown out of British Astronomy. Cheated out of the post he had been promised he struggles precariously in Europe to try and prove that his theory of Hidden Galaxies is right. That takes him to far flung observatories from the peaks of the Andes to the Cape of South Africa. Meanwhile the US is building the Shuttle to launch a large telescope into orbit but demands European participation in the venture. Frank Cotteridge, by now Bellfounder’s protégé, is tasked with lighting the European fuse. At conferences and in laboratories across the Continent the struggle begins to try and build the first electronic camera, to act as the great telescope’s eyes. In the 1970’s that looked impossible. And yet without such eyes the telescope will be blind. The race against the clock, and with rivals in California, begins. Personal and professional tensions drive wedges between the two friends while the race for Space forces them to rely ever more closely upon one another. Morgan rashly plans his revenge on Bellfounder, a battle only one of them can possibly survive.

At the same time Morgan is struggling, as a single parent, to bring up his son Curly and hold on to him in a bitter custody battle. When he loses, Curly is whisked away to Australia but then escapes and gets hopelessly lost in the bush.

The author was himself a professional astronomer, and a single parent, throughout this epoch. From 1976 until 2010 he was a key member of the Hubble Space Telescope team. Hubble’s story, our story, which he has been preparing to write for 20 years, is packed with dreams, heroes, shocks, villains, and the odd rare triumph. Like one of Magellan’s crew he saw great wonders and has tall tales to tell; the fight to get born, the Challenger disaster, the crippled mirror, the astronaut repair-missions, cancellation following the Columbia tragedy, renaissance, the race to prevent the space-craft dying, the huge discoveries… he was there; he was there; he was there. He knew the people, felt the pain, drank the wine. ENTIRE QUARTET ‘ called ‘Written in the Stars’ comprises: ‘Against the Fall of Night’ (1964 – 1974), ‘The Whispering Sky’ (1976 – 1983) , ‘Crouching Giant’ (1985 – 1995), ‘Beyond the Western Stars’ (1997 – 2012). All four paperbacks – each about 400 pages long – are out on Amazon, (2020), £12.99 or e-version £3.99.

ABOUT MY BOOK ‘THINKING FOR OURSELVES’.

September 29, 2020

Why not learn to think like Einstein? He attributed his success entirely to common sense. But what is Common Sense Thinking (CST) ? They don’t tell us in class because scholars don’t know how it works; it’s buried too deep inside us. So the author, who is a Space astronomer, has spent a lifetime unearthing it. Common Sense turns out to have nothing whatever to do with IQ, or with passing exams; it has to do with Curiosity, with the deliberate gathering of evidence, with a willingness to change one’s mind, and with the patience to wait until the Odds look decisive. But these common sense thinking skills are the very skills of the detective as well as the scientist; we can all learn them if we want to, whatever our educational attainments.

 To think efficiently for ourselves we require the right information and the right tools. At last the Internet is bringing an increasing flood of the kind of information we need to make crucial decisions for ourselves, and not have to rely any longer on expensive and often unreliable experts. But do we have the right mental tools? We do and we don’t. We do because Nature has embedded deep within us the sophisticated mental mechanisms  needed to survive in the perilous Stone-age out of which we evolved. We don’t, in the sense that we don’t know how those tools work, and so we cannot adapt them for best use in a modern world full of culture and technology. The author has unearthed those ingenious and previously unrecognised tools which Nature evolved  for dealing with conflicting evidence, for discounting bad clues, and for weighing up all the pros and cons.

The aim of this book is to open nature’s tool-bag and demonstrate her mental tools working one by one. The reader will end up equipped with an indispensable boy-scout’s penknife for the thinking mind.

         The book is aimed at two kinds of readers: those who feel they are educated – and those who feel they are not. The educated ones will discover that they have not learned Common Sense Thinking at school or university, and badly need to – while the uneducated ones will find that dropping out of education is no handicap if they now decide that they do want to think seriously and well. Anyone aged 14 or over could master it.

The approach is to work through numerous stories and examples, some serious, some light-hearted, all hopefully interesting and relevant. The book is really a series of detective stories in which we learn to work out rough odds on the various suspects (ideas) being guilty.

There are plenty of exercises for those who want to practice, with worked answers available free on the Internet.

Topics covered include:

  1. Different kinds of Thinking
  2. How scientists think and decide
  3. How to weight clues
  4. How to reckon the Odds
  5. Woolly thinking
  6. The Elephants in the room (Systematic Errors)
  7. Animal Intelligence
  8. Numbers and Errors in Thinking
  9. Why we don’t need Statistics any more.
  10. Common mistakes in Thinking and Deciding
  11. The extraordinary history of Thinking
  12. What is Science, and what is not?
  13. The meteoric ascent of mankind. What on Earth happened?

There are 16 chapters. Two hours devoted to each should equip the reader with the tools needed to go about tackling the hardest mental problems in life.
