Designed with classic images from scientific disciplines, these notebooks are built to ignite your curiosity. Ideas aren't meant to be all cramped up. The Hypothesis series comes with 192 of our signature split-use pages so your ideas have plenty of room. While developing this notebook series we polled more than 4000 notebook fanatics and determined that split-use pages provides a unique way to work with ideas--as a spread. Having paper for sketching, problem solving, or data gathering on one side and lines on the other means that the right side can be used for taking notes or longer writing passages, with the left side reserved for annotations and illustrations. Treat each pair of pages as a single space to let your thoughts run free. All of our notebook covers are designed by our small company in Portland, OR! We decided to make this notebook line because we were tired of notebooks with boring covers. For each design we dive through tons of classic scientific texts, scouring for the most stunning illustrations. We then build them into a collage that celebrates the beauty of the natural world--and the scientific process. Lastly, we work with amazing overseas partners who build us these top quality hardcover notebooks. We believe that as you read, study, attend lecture, or conduct research, your understanding of the material and your world deepens, becoming more nuanced and perhaps a little more elegant. The time you spend in the lab, the library or at your desk at home is worth respecting. We designed these notebooks as a beautiful place to archive your ideas. Take pride in everything you learn, record your brilliant thoughts, and respect your passion.

I’m in LOVE with this notebook. It is worth the money. I was worried after I purchased it but it’s worth it. It’s really well made and I love the design. I’m so happy I gave this notebook company a try

GORGEOUS and functional. Wish these came in a coil lay-flat version. I would buy them all.
