  • The actual father of electricity
  • There was no shortage of oldies in the 1500s. True, the average lifespan was low - but if you take out infant mortality from disease (no vaccination then!) it seems that lives were not much shorter than today. http://tudorblog.com/tag/tudor-average-life-span/ In fact, throughout recorded history, the expected lifespan for anyone surviving to adulthood was about 70 years.

  • Are EVs safer than gas-powered cars?
  • It doesn't much matter what kind of vehicle you are in, if it is on fire and you cannot exit. In a recent case, a dashboard fire (presumably from a short circuit) resulted in failure of the electrics, so the centrally controlled door locks could not operate. Fortunately, the doors were NOT locked at the time - but the driver was about to lock them, when he noticed the fire start. Something to consider, as cars - electric or fuel - become progressively more 'drive by wire'.

  • A hardware engineer's guide to becoming a software expert
  • I taught myself analog - enough to run a successful small manufacturing business. I have always paid someone else to write code when I need it, because I feel that I have no talent in that direction. But I know plenty of engineers who became self-taught coders who seem to get the job done, when they have to. I do not know whether they are what you would call an expert - but I do not think they have damaged their analog or other skills by doing so. There is a certain wisdom in knowing whether part of a system should be hardware or software. Having skills on both sides should make the choice easier.

  • Runaway Lithium-Ion batteries
  • Some interesting background on the battery assembly manufacturing here: http://www.dailykos.com/story/2013/01/18/1180205/-Engineer-on-787-electrical-system-fired-for-pointing-out-flaws#

  • Sound Affects
  • I have spoken to restaurant professionals about this issue, but they say that restaurants are actually INTENDED to sound loud, so that they appear to be more "happening". Also, the sooner the customers finish eating and leave, the better. So unless you are frequenting the top-end "all evening" establishments, don't expect change any time soon. Mind you, I expect part of the problem for Dr Hurrligan may be that (like me) he grew up in a pre-MP3 player world, and is still able to hear.
