From the Ground Up adds research into Minecraft. All vanilla items are tied to a technology and you can only craft those items when you have successfully researched that technology. You do this by experimenting with items until you get the desired result. The research is in the form of puzzles, inspired by the research in Thaumcraft. The mod also includes a nifty research book to see what you've learned and to look at what you can research next. The GUI of this book is greatly inspired by the Achievement GUI.
