Groundbreaking study shows how solar panels age after 30 years of use: 'It's an important message to the photovoltaic industry'. Astudy of six, 30-year-old arrays in Switzerland found them to still be working well, retaining more than 80% of their initial power.
“When we build our landscapes around places to go, we lose places to be.” Rick Cole shared by @MikeLydon of @StreetPlans & @NewUrbanism. #PlacemakingWeekEurope @placemaking_europe
Let this be an inspiration for us all. youtube.com/live/zkX2rIn_q…
“The first principle is that you must not fool yourself and you are the easiest person to fool.” ― Richard P. Feynman
@Vernon3Austin I love trains, but the future is individualized mass transit with autonomous electric vehicles taking you precisely to your destination. Tunnels are needed to address the fundamental choke points in cities. You can’t have 3D buildings and expect a 2D transport system to be…
"Engineering or technology is the making of things that did not previously exist, whereas science is the discovering of things that have long existed." - David Billington
“Let him not be grasping nor have his mind preoccupied with ... receiving perquisites, but let him with dignity keep up his position by establishing a good reputation. No work can be rightly done without honesty and incorruptibility.” - Vitruvius
“[I am] opposed to the laying down of rules or conditions to be observed in the construction of bridges lest the progress of improvement tomorrow might be embarrassed or shackled by recording or registering as law the prejudices or errors of today.” - Isambard Kingdom Brunel
“Engineering problems are under-defined, there are many solutions, good, bad and indifferent. The art is to arrive at a good solution. This is a creative activity, involving imagination, intuition and deliberate choice.” - Ove Arup
Jolie Laide youtu.be/NdIQdKt57vw?si… via @YouTube A classic lecture on architecture by Andres Duany.
“I’ve never seen a job being done by a five-hundred-person engineering team that couldn’t be done better by fifty people.” - C. Gordon Bell
Admit it!
“Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.” - Antoine de Saint-Exupery
The big problem with this graph is that as AI gets reduced to computation power, it further gets reduced to electricity to power the data centers that house the computation. The US is still ahead in model sophistication and quality but we are way behind on electricity…
Before studying engineering, if someone asked me what 1+1 is, I would have said "2." Now, I'd say "I'm pretty sure it's 2, but we'd better make it 3 just to be safe."
