Experts and expertise

Preamble In 2012 I explored the nature of expertise in an article that was mainly focused on expert witness expertise. A deeper exploration was triggered today when I discovered a statement made by the Care Quality Commission. Scroll down for more. This article will delve deep into the issues of experts and expertise, and prove ...

Attractiveness and success

At any one time I have several posts in the backend that I am drafting, some over weeks and others over months. Obviously a topic may hit me and I decide there and then to get on with that, instead of creating yet another draft. So this morning (Sunday 8th May 2022), the topic of ...

People want answers, hope and positivity

What people want is a simple answer that will put them back on a track that they should have been on. I’ve seen it before and I’ve seen it today 13th June 2021 again, between 17:45 to 18:10PM. In essence someone who referred to me as a ‘friend’ – and I am not their friend ...

For those who want to spend their life understanding

The Analysis Tool (also called REPL) – is JavaScript code used by Claude.ai to perform the thermal calculations and generate the data. This was invoked using the repl command.

React Component – This is the visualization code Claude.ai created as an artifact using React and the Recharts library to display the temperature profiles. This was created with the identifier “temp-profile” and used the artifact type “application/vnd.ant.react”.

It now all makes perfect sense – right? 🤣😂
