132. Seven Brief Lessons on Physics

Rating:  ☆☆☆1/2

Recommended by:   

Author:   Carlo Rovelli

Genre:  Non-Fiction, Science

86 pages, published March 1, 2016

Reading Format:  Book

 

Summary

In seven brief lessons, Italian theoretical physicist Carlo Rovelli guides readers with through the most transformative physics breakthroughs of the twentieth and twenty-first centuries.  This entertaining introduction to modern physics explains general relativity, quantum mechanics, elementary particles, gravity, black holes, the complex architecture of the universe, and the role of humans in the strange world Rovelli describes.  “Here, on the edge of what we know, in contact with the ocean of the unknown, shines the mystery and the beauty of the world,” Rovelli writes. “And it’s breathtaking.”  

 

Quotes

“We are made of the same stardust of which all things are made, and when we are immersed in suffering or when we are experiencing intense joy we are being nothing other than what we can’t help but be:  a part of our world.”

 

“Genius hesitates.”

 

“The very foundation of science is to keep the door open to doubt.”

 

“we are all born from the same celestial seed; all of us have the same father, from which the earth, the mother who feeds us, receives clear drops of rain, producing from them bright wheat and lush trees, and the human race, and the species of beasts, offering up the foods with which all bodies are nourished, to lead a sweet life and generate offspring”

 

“In his youth Albert Einstein spent a year loafing aimlessly. You don’t get anywhere by not ‘wasting’ time- something, unfortunately, that the parents of teenagers tend frequently to forget.”

 

“A university student attending lectures on general relativity in the morning and others on quantum mechanics in the afternoon might be forgiven for thinking that his professors are fools, or have neglected to communicate with each other for at least a century.”

 

“Quantum mechanics and experiments with particles have taught us that the world is a continuous, restless swarming of things, a continuous coming to light and disappearance of ephemeral entities. A set of vibrations, as in the switched-on hippie world of the 1960s. A world of happenings, not of things.”

 

“Nature is our home, and in nature we are at home. This strange, multicoloured and astonishing world which we explore – where space is granular, time does not exist, and things are nowhere – is not something that estranges us from our true selves, for this is only what our natural curiosity reveals to us about the place of our dwelling. About the stuff of which we ourselves are made.”

 

“All things are continually interacting with each other, and in doing so each bears the traces of that with which it has interacted: and in this sense all things continuously exchange information about each other.”

 

“It is hardly surprising that there are more things in heaven and earth, dear reader, than have been dreamed of in our philosophy – or in our physics.”

 

“Human beings often cling to their certainties for fear that their opinions will be proven false. But a certainty that cannot be called into question is not a certainty. Solid certainties are those that survive questioning. In order to accept questioning as the foundation for our voyage toward knowledge, we must be humble enough to accept that today’s truth may become tomorrow’s falsehood.”

 

“Life on Earth gives only a small taste of what can happen in the universe.”

My Take

In Seven Brief Lessons on Physics, Rovelli explores smallness (exploring the nature of matter at the subatomic level) and largeness (discussing the shape of the universe and the potential for other universes), the kind of topics that may make your head hurt if you think about them too much.  To his credit, my head didn’t hurt as I was reading Rovelli’s fascinating book.  He is an entertaining writer who has a lot of very interesting ideas to convey in just 86 pages.

74. Abundance: The Future Is Better Than You Think

Rating:  ☆☆☆1/2

Recommended by:  Christopher Funk

Author:   Peter Diamandis

Genre:  Non Fiction, Science, Economics

400 pages, published February 21, 2012

Reading Format:  Audio Book

 

Summary

In Abundance, tech entrepreneur turned philanthropist Peter Diamandis makes the case that the world is a lot better off than you think it is and that we are getting close to the time we will be able to meet and exceed the basic needs of every human being on earth.  Diamandis backs up this bold claim with extensive research and shows how four forces (exponential technologies, the DIY innovator, the Technophilanthropist, and the Rising Billion) are all helping to solve humanity’s biggest problems.  Abundance profiles many innovators doing amazing work including Larry Page, Steven Hawking, Dean Kamen, Daniel Kahneman, Elon Musk, Bill Joy, Stewart Brand, Jeff Skoll, Ray Kurzweil, Ratan Tata, and Craig Venter.   After discussing human needs by category—water, food, energy, healthcare, education, and freedom, Diamandis sets forth concrete targets for change and lays out a strategic roadmap for governments, industry and entrepreneurs to achieve these goals.

 

Quotes

“Quite simply, good news doesn’t catch our attention. Bad news sells because the amygdala is always looking for something to fear.”

 

“It’s incredible,” he says, “this moaning pessimism, this knee-jerk, things-are-going-downhill reaction from people living amid luxury and security that their ancestors would have died for. The tendency to see the emptiness of every glass is pervasive. It’s almost as if people cling to bad news like a comfort blanket.”

 

“Today Americans living below the poverty line are not just light-years ahead of most Africans; they’re light-years ahead of the wealthiest Americans from just a century ago. Today 99 percent of Americans living below the poverty line have electricity, water, flushing toilets, and a refrigerator; 95 percent have a television; 88 percent have a telephone; 71 percent have a car; and 70 percent even have air-conditioning. This may not seem like much, but one hundred years ago men like Henry Ford and Cornelius Vanderbilt were among the richest on the planet, but they enjoyed few of these luxuries.”

 

“I’ve got a hunk of gold and you have a watch. If we trade, then I have a watch and you have a hunk of gold. But if you have an idea and I have an idea, and we exchange them, then we both have two ideas. It’s nonzero.”

 

“Poverty was reduced more in the past fifty years than in the previous five hundred.”

“Teaching kids how to nourish their creativity and curiosity, while still providing a sound foundation in critical thinking, literacy and math, is the best way to prepare them for a future of increasingly rapid technological change.”

 

“The true measure of something’s worth is the hours it takes to acquire it.”

 

“Technology is a resource-liberating mechanism. It can make the once scarce the now abundant.”

 

“if everyone on Earth wants to live like a North American, then we’re going to need five planets’ worth of resources.”

 

“The negativity bias—the tendency to give more weight to negative information and experiences than positive ones—sure isn’t helping matters. Then there’s anchoring: the predilection for relying too heavily on one piece of information when making decisions. “When people believe the world’s falling apart,” says Kahneman, “it’s often an anchoring problem. At the end of the nineteenth century, London was becoming uninhabitable because of the accumulation of horse manure. People were absolutely panicked. Because of anchoring, they couldn’t imagine any other possible solutions. No one had any idea the car was coming and soon they’d be worrying about dirty skies, not dirty streets.”

 

“Today most poverty-stricken Americans have a television, telephone, electricity, running water, and indoor plumbing. Most Africans do not. If you transferred the goods and services enjoyed by those who live in California’s version of poverty to the average Somalian living on less than a $1.25 a day, that Somalian is suddenly fabulously rich.”

 

“Decentralized means learning cannot easily be curtailed by autocratic governments and is considerably more immune to socioeconomic upheaval.”

 

“A week’s worth of the New York Times contains more information than the average seventeenth-century citizen encountered in a lifetime.”

 

“If we were to forgo our television addiction for just one year, the world would have over a trillion hours of cognitive surplus to commit to share projects.”

 

“From the very beginning of time until the year 2003,” says Google Executive Chairman Eric Schmidt, “humankind created five exabytes of digital information. An exabyte is one billion gigabytes—or a 1 with eighteen zeroes after it. Right now, in the year 2010, the human race is generating five exabytes of information every two days. By the year 2013, the number will be five exabytes produced every ten minutes … It’s no wonder we’re exhausted.”

 

“Abundance is not about providing everyone on this planet with a life of luxury—rather it’s about providing all with a life of possibility.”

 

“Nanotechnology has the potential to enhance human performance, to bring sustainable development for materials, water, energy, and food, to protect against unknown bacteria and viruses, and even to diminish the reasons for breaking the peace [by creating universal abundance].”

 

“Today mammography requires an expensive, large, stationary machine that takes a crude, two-dimensional picture. But imagine a ‘bra’ that has tiny X-ray pixel emitters on the top and X-ray sensors on the bottom. It’s self-contained, self-powered, has a 3G or Wi-Fi-enabled network, and can be shipped to a patient in a FedEx box. The patient puts on the bra, pushes a button, and the doctor comes online and starts talking: ‘Hi. All set to take your mammogram? Hold still.’ The X-ray pixels fire, the detectors assemble and transmit the image, and the doctor reads it on the spot. The patient ships back the package, and she’s done. With little time and little money.”

 

My Take

Abundance is my kind of book.  I have always been a “glass half full” person and it is encouraging to read an optimistic take on the future of the world.  So many people think that we live in terrible times and that things are getting worse.  Peter Diamandis repeatedly demonstrates that folly of that mindset and that things have never been better.  Not only is the world-wide poverty rate declining dramatically and rapidly, but there are a plethora of technological innovations coming our way that will make life better and more meaningful.  Abundance made me realize how good we have it now and excited for all of the future developments that are coming our way soon.

34. Rise of the Robots : Technology and the Threat of a Jobless Future

Rating: ☆☆☆☆

Recommended by:  Chris Funk (my Dad)

Author:  Martin Ford

Genre:  Non-Fiction, Science, Futuristic

Info:  352 pages, published May 5, 2015

Format:  Book

Summary 

In Rise of the Robots, Martin Ford discusses what machine intelligence and robotics can accomplish, and warns employers and policy makers to face the implications.  As technology continues to accelerate and machines begin taking care of themselves, fewer people will be necessary.  The past solutions to technological disruption, especially more training and education, aren’t going to work, and we must decide soon whether the future will see broad-based prosperity or catastrophic levels of inequality and economic insecurity.  This book helps you understand what accelerating technology means for your economic prospects and those of your children, as well as for society as a whole.

 

Quotes

“Imagine that you get in your car and begin driving at 5 miles per hour. You drive for a minute, accelerate to double your speed to 10 mph, drive for another minute, double your speed again, and so on. The really remarkable thing is not simply the fact of the doubling but the amount of ground you cover after the process has gone on for a while. In the first minute, you would travel about 440 feet. In the third minute at 20 mph, you’d cover 1,760 feet. In the fifth minute, speeding along at 80 mph, you would go well over a mile. To complete the sixth minute, you’d need a faster car—as well as a racetrack. Now think about how fast you would be traveling—and how much progress you would make in that final minute—if you doubled your speed twenty-seven times. That’s roughly the number of times computing power has doubled since the invention of the integrated circuit in 1958. The revolution now under way is happening not just because of the acceleration itself but because that acceleration has been going on for so long that the amount of progress we can now expect in any given year is potentially mind-boggling. The answer to the question about your speed in the car, by the way, is 671 million miles per hour. In that final, twenty-eighth minute, you would travel more than 11 million miles. Five minutes or so at that speed would get you to Mars. That, in a nutshell, is where information technology stands today, relative to when the first primitive integrated circuits started plodding along in the late 1950s.”

“In 2012, Google, for example, generated a profit of nearly $14 billion while employing fewer than 38,000 people.  Contrast that with the automotive industry. At peak employment in 1979, General Motors alone had nearly 840,000 workers but earned only about $11 billion—20 percent less than what Google raked in. And, yes, that’s after adjusting for inflation.”

“Indeed, a 2013 study by Carl Benedikt Frey and Michael A. Osborne at the University of Oxford concluded that occupations amounting to nearly half of US total employment may be vulnerable to automation within roughly the next two decades.”

“Perhaps the most remarkable elder-care innovation developed in Japan so far is the Hybrid Assistive Limb (HAL)—a powered exoskeleton suit straight out of science fiction. Developed by Professor Yoshiyuki Sankai of the University of Tsukuba, the HAL suit is the result of twenty years of research and development. Sensors in the suit are able to detect and interpret signals from the brain. When the person wearing the battery-powered suit thinks about standing up or walking, powerful motors instantly spring into action, providing mechanical assistance. A version is also available for the upper body and could assist caretakers in lifting the elderly. Wheelchair-bound seniors have been able to stand up and walk with the help of HAL. Sankai’s company, Cyberdyne, has also designed a more robust version of the exoskeleton for use by workers cleaning up the Fukushima Daiichi nuclear plant in the wake of the 2011 disaster. The company says the suit will almost completely offset the burden of over 130 pounds of tungsten radiation shielding worn by workers.  HAL is the first elder-care robotic device to be certified by Japan’s Ministry of Economy, Trade, and Industry. The suits lease for just under $2,000 per year and are already in use at over three hundred Japanese hospitals and nursing homes.”

“Imagine the uproar when Uber’s cars start arriving without drivers.”

“In Japan, a new machine is able to select ripe strawberries based on subtle color variations and then pick a strawberry every eight seconds—working continuously and doing most of the work at night.”

“In a recent analysis, Martin Grötschel of the Zuse Institute in Berlin found that, using the computers and software that existed in 1982, it would have taken a full eighty-two years to solve a particularly complex production planning problem. As of 2003, the same problem could be solved in about a minute—an improvement by a factor of around 43 million. Computer hardware became about 1,000 times faster over the same period, which means that improvements in the algorithms used accounted for approximately a 43,000-fold increase in performance.”

“acquiring more education and skills will not necessarily offer effective protection against job automation”

“We eventually will have to move away from the idea that workers support retirees and pay for social programs, and instead adopt the premise that our overall economy supports these things. Economic growth, after all, has significantly outpaced the rate at which new jobs have been created and wages have been rising.”

“potentially unlimited output can be achieved by systems of machines which will require little cooperation from human beings.” The result would be massive unemployment, soaring inequality, and, ultimately, falling demand for goods and services as consumers increasingly lacked the purchasing power necessary to continue driving economic growth.”

“Knowing the ideological predisposition of a particular economist is often a better predictor of what that individual is likely to say than anything contained in the data under examination.”
