Emotional Contagions in Social Networks

These results highlight several features of emotional contagion. First, because News Feed content is not “directed” toward anyone, contagion could not be just the result of some specific interaction with a happy or sad partner. Although prior research examined whether an emotion can be contracted via a direct interaction (1, 7), we show that simply failing to “overhear” a friend’s emotional expression via Facebook is enough to buffer one from its effects. Second, although nonverbal ...

 Your Birth Star

Name any event in history and you will find a star out there whose light gives you a glimpse of something happening during the year of that event. Provided you are not a very young child, somewhere up in the night sky you can find your personal birth star. Its light is a thermonuclear glow that heralds the year of your birth. Indeed, you can find quite a few such stars (about 40 if you are 40; about 70 if you are 50; about 175 if you are 80 years old). When you look at one of your birth year ...

 Public School Mathematics are Like Drills

“Mathematics is not just a sequence of computations to be carried out by rote until your patience or stamina runs out—although it might seem that way from what you’ve been taught in courses called mathematics. Those integrals are to mathematics as weight training and calisthenics are to soccer. If you want to play soccer—I mean, really play, at a competitive level—you’ve got to do a lot of boring, repetitive, apparently pointless drills. Do professional players ever use those dril...

 Developing Puzzle Games Requires Experimentations

...you need fewer art assets to build a simple puzzle game. This is very good news for small developers, and for those just starting out in gaming. One or two people can build a world-class puzzle game. It would be next to impossible for one or two people to build a world-class third-person action game from scratch (and be finished by the end of the millennium). Puzzle games generally require puzzle pieces, such as blocks, widgets, shapes, or gizmos of some kind. Once you have built these obj...

 The Disparity Between Mothers and Fathers in Raising Chil...

Women spend a whopping 39 hours per week performing work related to child care. Today’s dad spends about half that—21.7 hours a week. This is usually couched as good news, too, for it is triple the amount of time guys spent with kids in the ’60s. Yet no one would call this equal, either. It is also still true that about 40 percent of dads spend two hours or less per workday with their kids, and 14 percent spend less than an hour. This imbalance in workload—along with financial confl...
