"Ignorance can be the ideal starting point from which to demystify a complicated subject"

I initially found this quote in a magazine around 2006 and tore it out and pinned it above my desk. I don't know the original source, however it appears in several places on the web attributed to different authors relating to writing biographies. I suspect that it is a variant on a common expression.

The personal website of John Welford


Dr John Welford MEng PhD CEng MIET MINCOSE

I am a chartered mechatronics and systems engineer with a PhD and engineering experience in the defence, automotive and rail industries. I am an active STEM ambassador, regularly giving talks and running activities in local schools and colleges. I also have a keen interest in visualisation and data presentation.

In my personal time I am a mountain biker and snowboarder, alongside numerous other small projects and distractions - some of which are mentioned on this site.

For further information please see my CV or feel free to contact me directly.
