It maps the top 160K titles in the new Open Syllabus 2.0 dataset, based on the frequency with which those texts are assigned (reflected in the size of the dot) and assigned together (reflected in the location and clustering of the dots). It's US centric given the composition of the syllabus collection, but also a unique representation of human knowledge as a collective, connected project.

Scientists develop the whitest paint ever
Ultra-white is the new Vantablack. Purdue University researchers developed the whitest white paint ever. It reflects 98.1% of sunlight. (The blackest black paint, Vantablack, absorbs 99.9% of visible light.)

This cool $40 humidifier works like a beast and doesn't leave a huge mess
The humidifier has been around for almost 100 years, going through all kinds of design variations and advancements along the way.

It seems like a pretty significant design flaw that most… READ THE REST
Check out 9 new deals on vacuums that are right on time for Spring Cleaning
