Phase angles

8th December 2017 I was in a courtroom the other day and the public prosecutor was asking questions . Unfortunately they were not engineering questions and I am an engineer. Thus, I did not understand the questions or why they were being asked. As a true engineer, I would say, "Ah, if you mean . . .", and I would... 

What should we ban?

1st December 2017 Edgar Allen Poe wrote that he took drugs, since "it has been the desperate attempt to escape from torturing memories, from a sense of insupportable loneliness and a dread of some strange impending doom”. Chuck Palahniuk wrote :“I admire addicts. In a world where everybody is waiting for some... 

Justice confused

24th November 2017 In the State vs Oscar Pistorius case, we all know what may have happened. The trial can also aspire to a record – the worst forensic evidence in South African legal history, ever. This does not relate to bloodstains and fingerprints, but simple scientific evidence that could have been tested on a... 

A little nuke never hurt nobody

17th November 2017 I recently told a group of people at a pub (a pub, can you believe?) that I thought Donald Trump was a "good idea".  There was the sort of silence that you get when the stage magician vanishes completely and then the sort of shouting that follows when Sandra Bullock asks who would like to go with... 

Far too high up

10th November 2017 Some time ago, I was in a court case as an expert witness. The advocate gave me a number to call him. It was his wife's cellphone number; he said it was no good me calling his cellphone because it was switched off, as the press never stopped calling him and he thought they may be bugging his... 

100 years from now

3rd November 2017 When the Trojans found a horse on the beach, I am quite sure that the first thing they thought was not: "How kind of those Greek lads", but rather: "Whatever are they up to?" We have similar horse. Ever friendly and kind Google lets us use Google Earth without charge. We even get a street view of... 

How we work at my consulting practice

27th October 2017 I thought I would write about how we, at my consulting practice, work. We have a fairly unique working system – perhaps the only one of its kind in South Africa. Read on. But, first, what we do. We are consulting engineers – specifically, consulting acoustics and electrical engineers. But this is... 

Just havin’ fun

20th October 2017 Oh, woe to all of you who are married to engineers. Engineers are generally useful people to have around. But, when watching TV, if something is shown that is not correct engineering-wise, the engineer will snort and launch into a detailed explanation as to why the TV is wrong. You want to... 

Bitcoins – a quick way to lose it all

13th October 2017 We all know that there IS a thing called a bitcoin. All over the show, there are stories about bitcoin investors who are now millionaires. What is the truth? A little story: Tim and I were working at a mining camp in the Congo. The mining camp was dry; no alcohol permitted. We followed the rules... 

Sparklepop and the Magic Dragon

6th October 2017 Sometimes I get involved in advertising film shoots. The first advertising film shoot that I attended was in the 1980s. It was held in a large open concrete yard owned by Eskom. The storyline was: a pretty woman is  walking along a sidewalk, next to a tree-lined road. We cut to a man who is...
