The research team, led by Wei Pan, analyzed all kinds of factors to tabulate the “social-tie density” of different cities–that’s the average number of people each resident will interact with personally. They looked at everything from the number of call partners with whom a cellphone user will end up sharing a cell tower to the number of people connecting through location-based social networks like Foursquare to the contagion rates of diseases spread only through personal contact. And they found that the higher a city’s social-tie density, the higher its levels of productivity and patents awarded.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
