Throwback Thursday: ‘Science Madness’ has 107 20th Century Volumes on Organic, Inorganic & Theoretical Chemistry, the Elements, Fermentations, and More!
Originally scanned for the Digital Library of India, some of the texts and PDFs on Science Madness have been archived there since 2003 – these days the archive currently stands at “50426 pages of reading and reference material in 107 volumes” – Impressive!
Shorter articles from the old Sciencemadness library remain available. Thanks go to BromicAcid for providing hosting for these old books during our time of lean bandwidth. Thanks also go to S.C. Wack for providing many of the books found here.
Most of these books are provided as PDF with JBIG2 compression. You will need Acrobat Reader 5.0 or above (or its equivalent) to view these files. A small number of books provided below are in DjVu format. To read them, you will need the the djview viewer provided by DjVuLibre or related projects.

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.
