Inventor notebooks, once considered hidden treasure troves of creativity, have fallen out of fashion. Zimmer Barnes’ “Ramblings of a Mad Scientist” marks their roaring comeback. This collection invigorates and inspires with one hundred original concepts, ideas, and inventions spanning many topics, including transportation, mobile devices, wearable electronics, games, emerging technologies, and more. All ideas contained within are free to use, shared with the public domain, as opposed to being patented. Barnes takes casual readers and aspiring inventors alike through his personal journey of discovery, while prompting th to tap into their own inner creativity and imagine a stranger tomorrow for all of us.
