Hacker Calculus

Many hackers are self-taught and avoid powerful math tools that might let them take creations to the next level. We aim to create a structured set of modules consisting of hands-on 3D printing and electronics projects, with thorough text documentation and minimal supporting algebra. These modules will teach calculus in this hacker style both for self-learners and others, like the visually impaired, who need hands-on learning.

When Isaac Newton developed calculus in the 1600s, he was trying to tie together math and physics in an intuitive, geometrical way. But over time math and physics teaching became heavily weighted toward algebra, and less toward geometrical problem-solving. However, many practicing mathematicians and physicists will get their intuition geometrically first and do the algebra later. We want to let people get to that point directly without passing through (much) algebra, particularly people who learn best by making something.

3D Prints for Teachers of the Visually Impaired

Often students with visual impairments have difficulty with concepts based on visual/spatial relationships, particularly in math and science. 3D prints offer an unprecedented asset for their teachers, and 3D printers are becoming affordable. But these teachers need help designing models. We have been volunteer mentors to various groups working on figuring out the best ways to use 3D printing for the visually impaired. Our goal with this project is to document some simple, practical conventions for designing models, and lay the groundwork so that interested parties can create the needed designs. We know that schools have 3D printers and want to teach design thinking to their students. This project creates a minimalist open-source way to link teachers who need design files and (sighted) students who want projects to do. We want students to create the designs for the needed models, learning science, math and other subjects while helping their visually-impaired peers.

American Association for Advancement of Science Pacific Division Scientific Maker Event

It is more feasible to create your own lab equipment than ever before with the advent of 3D printing, low-cost Arduino sensors and other “maker” technologies. It is also possible to have citizen scientist collaborators who cannot only take data for you, but follow open-source plans to create their own equipment. Are you one of the pathfinders that has actually done this? If so, please consider bringing your creation to Pomona, CA June 11-15, 2018 for the AAAS Pacific Division’s second Scientific Maker Exhibit. Group exhibits are welcome. Objects that are the subject of work in progress or recent crowdfunding campaigns or equivalent open-source projects are encouraged.
