Insight from the Sociology of Science
CHAPTER 7 INSIGHT FROM THE SOCIOLOGY OF SCIENCE Science is What Scientists Do It has been argued a number of times in previous chapters that empirical adequacy is insufficient, in itself, to establish the validity of a theory: consistency with the observable ‘facts’ does not mean that a theory is true,1 only that it might be true, along with other theories that may also correspond with the observational data. Moreover, empirical inadequacy (theories unable to account for all the ‘facts’ in their domain) is frequently ignored by individual scientists in their fight to establish a new theory or retain an existing one. It has also been argued that because experi- ments are conceived and conducted within a particular theoretical, procedural and instrumental framework, they cannot furnish the theory-free data needed to make empirically-based judgements about the superiority of one theory over another. What counts as relevant evidence is, in part, determined by the theoretical framework the evidence is intended to test. It follows that the rationality of science is rather different from the account we usually provide for students in school. Experiment and observation are not as decisive as we claim. Additional factors that may play a part in theory acceptance include the following: intuition, aesthetic considerations, similarity and consistency among theories, intellectual fashion, social and economic influences, status of the proposer(s), personal motives and opportunism. Although the evidence may be inconclusive, scientists’ intuitive feelings about the plausibility or aptness of particular ideas will make it appear convincing. The history of science includes many accounts of scientists ‘sticking to their guns’ concerning a well-loved theory in the teeth of evidence to the contrary, and some- times in the absence of any evidence at all. -
The Joys and Burdens of Our Heroes 12/05/2021
More Fun Than Fun: The Joys and Burdens of Our Heroes 12/05/2021 An iconic photo of Konrad Lorenz with his favourite geese. Photo: Willamette Biology, CC BY-SA 2.0 This article is part of the ‘More Fun Than Fun‘ column by Prof Raghavendra Gadagkar. He will explore interesting research papers or books and, while placing them in context, make them accessible to a wide readership. RAGHAVENDRA GADAGKAR Among the books I read as a teenager, two completely changed my life. One was The Double Helix by Nobel laureate James D. Watson. This book was inspiring at many levels and instantly got me addicted to molecular biology. The other was King Solomon’s Ring by Konrad Lorenz, soon to be a Nobel laureate. The study of animal behaviour so charmingly and unforgettably described by Lorenz kindled in me an eternal love for the subject. The circumstances in which I read these two books are etched in my mind and may have partly contributed to my enthusiasm for them and their subjects. The Double Helix was first published in London in 1968 when I was a pre-university student (equivalent to 11th grade) at St Joseph’s college in Bangalore and was planning to apply for the prestigious National Science Talent Search Scholarship. By then, I had heard of the discovery of the double-helical structure of DNA and its profound implications. I was also tickled that this momentous discovery was made in 1953, the year of my birth. I saw the announcement of Watson’s book on the notice board in the British Council Library, one of my frequent haunts. -

Discovery of DNA Structure and Function: Watson and Crick By: Leslie A
01/08/2018 Discovery of DNA Double Helix: Watson and Crick | Learn Science at Scitable NUCLEIC ACID STRUCTURE AND FUNCTION | Lead Editor: Bob Moss Discovery of DNA Structure and Function: Watson and Crick By: Leslie A. Pray, Ph.D. © 2008 Nature Education Citation: Pray, L. (2008) Discovery of DNA structure and function: Watson and Crick. Nature Education 1(1):100 The landmark ideas of Watson and Crick relied heavily on the work of other scientists. What did the duo actually discover? Aa Aa Aa Many people believe that American biologist James Watson and English physicist Francis Crick discovered DNA in the 1950s. In reality, this is not the case. Rather, DNA was first identified in the late 1860s by Swiss chemist Friedrich Miescher. Then, in the decades following Miescher's discovery, other scientists--notably, Phoebus Levene and Erwin Chargaff--carried out a series of research efforts that revealed additional details about the DNA molecule, including its primary chemical components and the ways in which they joined with one another. Without the scientific foundation provided by these pioneers, Watson and Crick may never have reached their groundbreaking conclusion of 1953: that the DNA molecule exists in the form of a three-dimensional double helix. The First Piece of the Puzzle: Miescher Discovers DNA Although few people realize it, 1869 was a landmark year in genetic research, because it was the year in which Swiss physiological chemist Friedrich Miescher first identified what he called "nuclein" inside the nuclei of human white blood cells. (The term "nuclein" was later changed to "nucleic acid" and eventually to "deoxyribonucleic acid," or "DNA.") Miescher's plan was to isolate and characterize not the nuclein (which nobody at that time realized existed) but instead the protein components of leukocytes (white blood cells). -

Watson's Way with Words
books and arts My teeth were set on edge by reference to “the stable form of uranium”,a violation of Kepler’s second law in a description of how the Earth’s orbit would change under various circumstances, and by “the rest mass of the neutrino is 4 eV”. Collins has been well served by his editor and publisher, but not perfectly. There are un-sort-out-able mismatches between text and index, references and figures; acronyms D.WRITING LIFE OF JAMES THE WATSON in the second half of the alphabet go un- decoded; several well-known names are misspelled. And readers are informed that Weber’s death occurred “on September 31, E. C. FRIEDBERG, 2000”. Well, Joe always said he could do things that other people couldn’t, but there are limits. Incidentally, my adviser was partly right: I should not have agreed to review this book. It is very much harder to hear harsh, some- times false, things said about one’s spouse after he can no longer defend himself. I am not alone in this feeling. Carvel Gold, widow of Thomas Gold, whose work was also far from universally accepted (see Nature 430, 415;2004),says the same thing. ■ Virginia Trimble is at the University of California, Irvine, California 92697-4575, USA.

Reflections on the Historiography of Molecular Biology
Reflections on the Historiography of Molecular Biology HORACE FREELAND JUDSON SURELY the time has come to stop applying the word revolution to the rise of new scientific research programmes. Our century has seen many upheavals in scientific ideas--so many and so varied that the notion of scientific revolution has been stretched out of shape and can no longer be made to cover the processes of change characteristic of most sciences these past hundred years. By general consent, two great research pro- grammes arising in this century stand om from the others. The first, of course, was the one in physics that began at the turn of the century with quantum theory and relativity and ran through the working out, by about 1930, of quantum mechanics in its relativistic form. The trans- formation in physics appears to be thoroughly documented. Memoirs and biographies of the physicists have been written. Interviewswith survivors have been recorded and transcribed. The history has been told at every level of detail and difficulty. The second great programme is the one in biology that had its origins in the mid-1930s and that by 1970 had reached, if not a conclusion, a kind of cadence--a pause to regroup. This is the transformation that created molecular biology and latter-day biochemistry. The writing of its history has only recently started and is beset with problems. Accounting for the rise of molecular biology began with brief, partial, fugitive essays by participants. Biographies have been written of two, of the less understood figures in the science, who died even as the field was ripening, Oswald Avery and Rosalind Franklin; other scientists have wri:tten their memoirs. -
Journal of Science (Including the History & Philosophy of Science)
St Benedict’s LSC Journal of Science (including the History & Philosophy of Science) Volume 3 ∙ Number 1 ∙ January 2019 Published by the Science Department, St Benedict’s Catholic School LSC, Bury St Edmunds, Suffolk, UK. Editor-in Chief: Mr J Gregory Associate Editors: Mrs F Green, Mr F Sousa, Mrs R Blewitt and Mr C McGraffin EDITOR’S NOTE: Welcome to the first issue of Volume 3 of our Journal of Science. I apologise for the fact that it has been a year since the last issue and hope to make up for it during the Spring and Summer terms this year! This issue features a variety of papers and posters containing many fascinating pieces of information ranging from one author’s ultrasound scan when she was only 12 weeks old and still inside her mother’s womb; biographies of some famous scientists; all about different states of matter; animals that don’t have bones; and three very thoughtful and insightful papers comparing the work of Rosalind Franklin and that of Watson & Crick in the discovery of the structure of DNA – a topic that still causes much debate. We take the celebration of New Year’s Day, January 1st, rather for granted these days but, when you think about it, January 1st is in the middle of Winter and, although the days are getting longer, nothing much else is going to happen for at least another couple of months. Wouldn’t it be better to mark the event on the date of the Winter Solstice, December 21st, which marks the moment when the days actually do start to get longer? Or maybe at the Vernal (Spring) Equinox, 20th March, when days become longer than nights and the first green shoots of growth are appearing in nature? The fact is that, in Western Civilisation, the so-called ‘New Year’ has varied throughout. -
