"Erosion of the leading edge of wind turbine blades by droplet impingement wear, reduces blade aerodynamic efficiency and power output. Eventually, it compromises the integrity of blade surfaces. Elastomeric coatings are currently used for erosion resistance, yet the life of such coatings cannot be predicted accurately." https://www.sciencedirect.com/...
Of course, nobody is ever going to use Alexa for anything remotely related to hifi, but this is certainly not something we would want to see spread anywhere else.
Allow me to introduce you to the phrase "works with Alexa", already featured in TVs and A/V receivers.
were also talented artists and/or musicians. Their hobbies have included painting, clay sculpture, and playing in orchestra or other bands. The best artists I have known, were "only" artists, but that wasn't a limitation of their abilities, but rather a limitation of their education or of the brainwashing they received about how they lacked the "smarts" to be anything but an artist.
If you are reading this and are pre-college, and have talents in the arts, and believe (or are being told) you are somehow lacking the smarts to pursue engineering, then I encourage you to reconsider. The people telling you this are probably HS counselors or others that are not engineers. They do not know engineering except by proxy of the students they've encouraged in that direction. Their failure isn't in the students that pursued engineering and washed out. Their failure was in the students they encouraged to do pursue liberal arts instead, that could have been great engineers.
One of the very best engineers I've ever worked with was--when she was in high school--a mostly C's student that drew horses in class instead of taking notes and did not know what she wanted to pursue if she went to college. Her father suggested she pursue mechanical engineering and lacking any other particular ambition, did just that. She discovered college classes weren't as crappy as in HS and she did her homework, got good grades, graduated and got a job at NASA designing cool shit.
She regularly cites her creative talents as giving her an edge in her design work. When she was just staring out and needed to think through a mechanism design, she made paper crafted models with tape and paperclips to gain understanding and validate her ideas, and later discovered this wasn't an uncommon practice among engineers at NASA.
I know all this because I talked with her about education paths when we were both mentoring a HS robotics club. She was incensed at the teacher running the club that would direct the "artsy" kids to create the posters and design the t-shirts for the club, rather than have them focus on the robotics. The teacher was setting those kids "artsy" kids expectations low and perpetuating the stereotyping that participating in a robotics club could have overcome.
Liberal arts are important to society and artists are certainly important to society, but being an artist and making a living are, except for a rare few, not the same activity. Whatever spark of creativity and originality that exists inside you is valuable and usable in engineering.
If I want to abuse statistics, I'd say the data clearly shows that on the particular day of this accident it was thousands of times safer to be in a human driven vehicle when passing the deficient barrier than in an auto-piloted Tesla.
Wanting to highlight your point. If the conditions that led to the crash can reliably crash the all auto-piloted Teslas, then the statistic that matters is how likely is that condition going to occur for all Teslas on the road. Ok, make an estimate and take the gamble. But more broadly, we can't know the frequency or likelihood of all the conditions that could screw up autopilot ahead of time. Those circumstances have to be "discovered".
A data point I want have: how often do auto-pilot users become negligent and ignore the warnings to re-take control? It seems that ignoring the warnings should fall under some flavor of existing laws, re: "reckless disregard for safety".
On the whole, however, I'd rather navigate roads filled with teenagers, elderly, sleepy, and drug-impaired drivers all using auto-piloted Teslas, than the current alternative.
