To psychological researchers, happiness is life experience marked by a preponderance of positive emotion. Feelings of happiness and thoughts of satisfaction with life are two prime components of subjective well-being.

The scientific pursuit of happiness and positive emotion is also the first pillar of the new positive psychology first proposed in Martin E. P. Seligman's 1998 American Psychological Association presidential address. Positive psychologists also study positive character strengths and virtues and positive social institutions.

Assessing Happiness

Psychologists assess people's happiness with varied measures. The simplest is a single item that has been posed to hundreds of thousands of representatively sampled people in many countries: "Taken all together, how would you say things are these days─would you say you are very happy, pretty happy, or not too happy?"

We all know how to make money: get a job, make things and sell them, maybe play the stock markets. But what about creating a whole new kind of money?

This is just what the digital cash known as bitcoin has done. Bitcoin — the U.S. Treasury calls it a “decentralized virtual currency” — can be used to buy products and services. The largest reported bitcoin purchase was a $500,000 villa on the Indonesian island of Bali, but it is also used for smaller items such as sandwiches and candy bars. …

This whole world is a story. I’ve read every page except the last one. I need to find out how it ends. I want to know what this all means.

The Man in Black, Westworld

Philosophers as far back as Plato, millennia ago, speculated that what we see may not be real at all. With the advent of computers, the idea took on new life, especially in recent years, with films like InceptionDark City, and the Matrix trilogy. Is it possible that the world is just a computer simulation?

Computers now process huge amounts of data, and some of the most intense and productive tasks involve simulations. Simulations consider multiple variables and use artificial intelligence to analyze them and examine outcomes. Some simulations are games. Some are models of real-life situations, such as the spread of diseases. Some are history simulators, which can be games (like Sid Meyer’s Civilization) or can mimic the real-life growth of society over time. That’s how simulations run now, but computers keep getting faster. Processing power has doubled periodically for decades, and computers 50 years from now may well be millions of times more powerful than any today. Better computers would bring much bigger and better computer simulators—including history simulators. If computers get powerful enough, they would create history simulations so real that the self-aware beings within them would have no idea they were part of a program. Think that’s too far out there? Harvard’s Odyssey supercomputer can simulate 14 billion years in only a few months. …

Over the last twenty years, more and more studies measuring the effect of loneliness suggest it is an important public health concern. For example, there is evidence that the risk of developing and dying from heart disease can depend on the strength of one's social network of friends and family, and that being recently widowed can increase one's odds of dying. And for people with Alzheimer's, even at more severe levels of the disease, cognitive function remains higher in those who have larger social networks.

After offering some examples of loneliness, this article touches on some emerging themes and issues, such as problems of defining the multidimensional nature of loneliness, some of the evidence that is driving its rising profile as a public health concern, how it differs from solitude, and lastly itemizes suggestions about how to overcome and cope with it. …

Some historical heroes get all the glory and praise even though they didn’t really deserve it. Others perform great deeds but are barely recognized. For some reason, whether it be by race, gender, job, or just that they don’t really fit into the historical narrative. Others are famous for one reason or another but aren’t really fully recognized for their work because they may share some unlikable quality the status quo doesn’t like or their accomplishments just get lost in the historical record. In some ways, history doesn’t do much justice to them either. …

We live in a fascinating era. Technology and science move at an incredible speed and the forecasts about the next big thing are a common buzz in our daily lives.

As Mark Twain wrote:

Prediction is very difficult, especially if it’s about the future.

Technology, connectivity and globalisation had more impact in humankind for the last 20 years than centuries of human development. Before looking at what the future of finance might look like – and dive into scenarios such as decentralised payments and settlement systems, peer-to-peer lending, crowdfunding, robot advisers and riskier trading as financial transactions becomes more electronic, we must first understand how we gotten here. …
