23.01.2022 Book Review: Engineering Iron and Stone The American Society of Civil Engineering (ASCE) Press published a book titled 'Engineering Iron and Stone: Understanding Structural Analysis and Design Methods of the Late 19th Century' by Thomas E Boothby in 2015. The purpose of the book, as outlined by the author, is primarily to retain some knowledge of past engineering design techniques for present and future generations. Whilst the book is relatively concise at just 216 pages, it ...packs a wealth of information on empirical, analytical and graphical methods for bridges, arches, columns, beams and other structures made of iron and stone. The author compares and contrasts the techniques against modern design standards, where certain methods such as the graphical method could analyse a complex structure more efficiently than some of the computing programs used today, which rely on a less efficient brute force analysis (only made efficient by computing power). Many cities are beautified by the historic structures made of iron and stone and this book helps modern readers, particularly engineers, better appreciate the genius of history and possibly encourage some engineers to look further at these techniques. This book is rated at 8/10, with some room for improvement in clarity of image qualities and some of the wording. https://sp360.asce.org//Product-Details/productId/233130466

19.01.2022 Sincere apologies, it's been a few months since the last post on this page. It is time to make a comeback. Going forward, posts will be less frequent (ie. not typically daily), however new content will look to be included with a lesser focus on historical information, rather including some new posts about current affairs such as coronavirus, the state of engineering in Australia, looking at modern standards and more. Please engage in commenting and discussion to help foster knowledge sharing and debate with a view to educating ourselves.

13.01.2022 Data analysis and statistics forms an important basis of engineering. They are required to be analysed and assessed within the pervue of the scientific method, which seeks to assess operations within multivariate systems by imposing controls on some inputs. For example the relationship between coronavirus cases and deaths in statistics. Full post to follow...

07.01.2022 Coronavirus Cases vs Deaths in the United Kingdom There are some interesting statistics out of the UK, as they pertain to the coronavirus pandemic, which are available from Worldometer (https://www.worldometers.info/coronavirus/country/uk/). In the attached screen clips from Worldometer, data for the daily cases and deaths totals are shown with highlights over the peaks and the 7-day moving average lines turned on.... For the daily cases 7-day moving average, the first wave maximum was 4,999 (14 Apr 2020) and the second wave maximum was 59,660 (9 Jan 2021), meaning an increase of 1,193%. For the daily deaths 7-day moving average, the corresponding stats were 943 (14 Apr 2020) and 1,248 (23 Jan 2021), meaning an increase of 132%. In other words, the number of coronavirus cases in the UK increased at a rate of NINE times the coronavirus deaths and therefore this poses a serious question: how can that statistical anomaly be possible?

03.01.2022 Given the commencement of the Australian roll-out of the COVID-19 vaccine, it is worth sharing information here specifically as it relates to the provisional approval from the Therapeutic Goods Administration (TGA) on 25 January 2021. The information of the TGA assessment and provisional approval is available here: https://www.tga.gov.au/auspar/auspar-bnt162b2-mrna-comirnaty It's worth reading all the documents in their entirety to familiarise yourself, however some excerpts ...from the AusPAR Product Information Report included in the attached images. Lastly, to clarify how the 95% efficacy figure was derived from the study, there were 17,411 subjects in the vaccine group, of which 8 developed COVID-19 symptoms and 17,511 subjects in the placebo group, of which 162 developed COVID-19 symptoms. Dividing 8 by 162 and subtracted from 1 yields 0.95 or 95%.
