Only the rascals think they win

‘I learned that you always lose.  Only the rascals think they win.’ This is quote from Nausea by Jean-Paul Sartre.  ‘Rascals’ has become a cute word for a villain; but, the Merriam-Webster Dictionary defines it as ‘a mean, unprincipled person’.  It’s a rather pessimistic view of life – that everyone loses; only some people don’t see it.  Or perhaps Sartre is saying that if you are successful then it’s not as a result of your own efforts but of the efforts of others around you and the opportunities that come your way;  so, if you think you won then you must be mean and unprincipled.

I was puzzled by the always losing until I read an Op-Ed by Lilliana Mason in the New York Times on June 7th, 2018.  She explains that as individuals we hold multiple identities, as a partner, parent, employee, feminist, etc; and that some of these identities are more important to us than others.  She says that, at any one time, the most important identity tends to be the one whose status is most threatened.  This could make you feel as if you are always losing.  In other words we tend to focus on the negative – our brains are wired to blame rather than praise [see ‘Depressed by exams‘ on January 31st, 2018 and ‘Happenstance, not engineering‘ on November 9th, 2016].  Or as my editor commented: ‘we tune into the threats in our lives – it’s a matter of survival’.

Establishing fidelity and credibility in tests & simulations (FACTS)

A month or so ago I gave a lecture entitled ‘Establishing FACTS (Fidelity And Credibility in Tests & Simulations)’ to the local branch of the Institution of Engineering Technology (IET). Of course my title was a play on words because the Oxford English Dictionary defines a ‘fact’ as ‘a thing that is known or proved to be true’ or ‘information used as evidence or as part of report’.   One of my current research interests is how we establish predictions from simulations as evidence that can be used reliably in decision-making.  This is important because simulations based on computational models have become ubiquitous in engineering for, amongst other things, design optimisation and evaluation of structural integrity.   These models need to possess the appropriate level of fidelity and to be credible in the eyes of decision-makers, not just their creators.  Model credibility is usually provided through validation processes using a small number of physical tests that must yield a large quantity of reliable and relevant data [see ‘Getting smarter‘ on June 21st, 2017].  Reliable and relevant data means making measurements with low levels of uncertainty under real-world conditions which is usually challenging.

These topics recur through much of my research and have found applications in aerospace engineering, nuclear engineering and biology. My lecture to the IET gave an overview of these ideas using applications from each of these fields, some of which I have described in past posts.  So, I have now created a new page on this blog with a catalogue of these past posts on the theme of ‘FACTS‘.  Feel free to have a browse!

Nauseous blogging?

In his novel ‘Nausea’, Jean-Paul Sartre suggests that at around forty, experienced professionals ‘christen their small obstinacies and a few proverbs with the name of experience, they begin to simulate slot machines: put in a coin in the left hand slot and you get tales wrapped in silver paper, put a coin in the slot on the right and you get precious bits of advice that stick to your teeth like caramels’.  When I first read this passage a few weeks ago, it seemed like an apt description of a not-so-young professor writing a weekly blog.

I am on vacation combining the positive effects of reading [see ‘Reading offline‘  on March 19th, 2014] and walking [see ‘Gone walking‘ on April 19th, 2017] with a digital detox [see ‘In digital detox‘ on July 19th, 2017]; but, through the scheduling facilities provided by WordPress, I am still able to dispense my slot machine homily. I will leave you to decide which posts are from the left and right slots.
