Knotebooks are a new way to learn science online. Want to learn about gravity? We'll show you clear, concise and correct knotebooks so you can understand the concepts.

But what if it doesn't click? Everyone has a different learning style, right? And only you know how you learn best...

So make that section easier! Or swap that explanation out for a video. Or maybe see how students at MIT or Harvard learn about gravity. Swap out any section in any knotebook with different material, difficulty levels, formats and styles until the explanations are just right for you.

Keep clicking until it clicks, then save that lesson to your favorites and share it with classmates and friends.

What are knotebooks? Knotebooks are what ninjas use to learn science. Knotebooks are textbook killers.

We've all had the experience of coming across a section in a textbook that you just don't understand. Well, with Knotebooks you can make any explanation easier with the click of a button!

Just click on the grey arrow in the title bar and select easier to swap this knote out for one that explains the same concept, but perhaps is more your style.

Go ahead, give it a try!

You can even swap out an HTML knote (such as this) for a video knote by selecting it from the dropdown menu before you hit easier or harder.

Now you can work your way through any knotebook, completely customizing it to your level of understanding and preferred format. Why not save it?

Once you're satisfied with your changes, click Save to My Favorites in the knotebook title bar:

Go ahead, I'll wait.

Now you can revisit your saved knotebook from your profile page whenever the mood strikes you. Just click on the Profile link in the navigation bar up top.

To create a knotebook from scratch, just click on the create button in the navigation bar.

First off, give your knotebook a title and a brief description, then hit Create knotebook. (Don't worry because you can change this later!)

You have three ways to add content:

1. Create a knote with text, pictures, etc.
2. Create a knote with a Youtube video
3. Pull in a knote someone else created

Click Add a new knote, give it a title and complete the description by selecting from the dropdowns. Make sure to add the one or two concepts covered in your new knote in the about field. Now just craft your knote! Add pictures, maybe some math equations, perhaps a table or two, whatever you want.

Once you're done, enter the reference or select This is my original content and we'll generate it for you. Finally, hit Save knote and you're done!

To pull in a knote someone else made, just click Search for knotes and enter the concept you're looking for. Then just choose from the results and hit Use ths knote to add it.

Rinse and repeat!
