Is mathematics our physical world because it can only be describes in mathematics? Physics and its fundamental constants [#] (ie speed of light, sound, gravity, ...). Is mathematics the essence of the universe? // Lesson for Engineering & Programming min 48:30 :: "Engineers live in the domain of the approximate. We are fundamentally interested in the practical. So, frequently we make approximations. We cut corners. We omit terms and equations to get things that are simple enough to suit our purposes and meet our needs. [...] For us engineers we don't get paid to do things right. We get paid to do things just right enough." *Adam Steltzner, NASA (Jet Propulsion Laboratory)

The Fermi Paradox — Where Are All The Aliens? (1/2) - YouTube
The Fermi Paradox II — Solutions and Ideas – Where Are All The Aliens? - // &! Earth is on the brink of a "mass extinction event" which could be equivalent in scale to the one that killed off the dinosaurs 65 million years ago, a landmark study by an international group of scientists has concluded. Researchers warned that deforestation, climate change, and overfishing have driven extinction rates to 1,000 times their normal level, Reuters reports. Duke University biologist and conversation expert Stuart Pimm says that "time is running out" to avert the threat of mass extinction. ADVERTISING If the crisis is to be avoided, humans need to make large scale changes immediately, Pimm says. - // WE HAVE A DECADE OR TWO till tipping point of no return!

Travis Kalanick of Uber - TWiST #180 - YouTube
MVP - minimal viable product, test of thesis; they rented a handful of cars with drivers in SF & build little app, the rest is history. make move to not have drivers but enable people to be drivers with income. Uber - elegance, design, ... this is now a brand, a status symbol. +++ on demand lifestyle, making magic happen via technology - employing STEM people. +++ could, because of supply liquidity, deliver, at premium, food to your door. +++ because of their technology, their platform, they either could licence out their problem solving platform (ie demand prediction - people just opening up the app - math is an operational cornerstone) to air transportation and or goods transportation. +++ Travis Kalanick at Startup School 2012 - >> multi-product company - for different budgets. Operations, Scaling - one problem that needed solving, a Playbook for expanding from one city to the next. Changing how u live, over months. not decades, today's age.

The mathematical equation that caused the banks to crash | Science | The Observer
The Black-Scholes equation has its roots in mathematical physics, where quantities are infinitely divisible, time flows continuously and variables change smoothly. Such models may not be appropriate to the world of finance. Traditional mathematical economics doesn't always match reality, either, and when it fails, it fails badly. Physicists, mathematicians and economists are therefore looking for better models.

At the forefront of these efforts is complexity science, a new branch of mathematics that models the market as a collection of individuals interacting according to specified rules. These models reveal the damaging effects of the herd instinct: market traders copy other market traders. Virtually every financial crisis in the last century has been pushed over the edge by the herd instinct. It makes everything go belly-up at the same time. If engineers took that attitude, and one bridge in the world fell down, so would all the others.
