The word "expert" is an interesting one. It denotes someone with a high level of skill and experience in their field. It also, as you've said, is a hint that someone is "done" - they've climbed their mountain and are standing at the summit.

I prefer to call myself a specialist, not an expert. Being a specialist does not preclude continuously learning and growing. It's more like farming a plot of land than climbing a mountain. The former takes work and effort, and you can get more and more out of your field.

One particular system caught our eye…


Around the middle of last year, I came across a blog post by Deepmind, a London-based artificial intelligence company owned by Google.

As a long-time energy efficiency engineer, the prospect of anyone gaining a 40% improvement in their energy use sounded incredible. I had to know more.

Google, like all…


I was able to recover my lost notebook. Here’s how I did it.

I love Evernote. It has become as second brain for me, recording and indexing all the pieces of data I would normally have scattered in paper or across my hard drive.

I was tidying up my Evernote…
