How the Invention of Spreadsheet Software Unleashed Wall Street on the World
At one point or another, you have had to use spreadsheet software for school, work, or personal use. Either way, it is interesting to see the correlation between it and Wall Street as we know it today.
In 2010, a pair of researchers published a controversial economics paper. It was cited by UK politicians to justify austerity measures that sparked economic and employment crises, and anti-austerity protests—measures that the UN later called “punitive, mean-spirited, and often callous” inflicting “great misery.” In 2013, however, this widely influential paper was found to have been substantially off in its estimates, thanks in part to a simple spreadsheet error: specifically, “a few rows left out of an equation to average the values in a column,” the Guardian wrote at the time.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
