Welcome!

Our goal is that more physicists share what they learn so that not everyone has to reinvent the wheel.

Currently there aren't many students and professional physicists who do this. The only things that are shared publicly are polished finished projects. However, displaying the struggles during the learning process and informal notes can be extremely valuable. On the one hand, beginners learn better by reading the notes of other beginners who just learned the subject. On the other hand, writing and sharing notes helps to get early feedback and is a great way refine your understanding.

Why aren't more people sharing informal notes online? Common obstacles are questions like:

How do I set-up a reliable online notebook that supports LaTeX? Which software should I use?
Will anyone care about my notes?

We answer these questions and offer free online notebooks for physicists and students. In addition, we highlight the best existing physics notes such that they get the attention they deserve.

Jakob Schwichtenberg's Notes

“This my attempt to collect those things that help me understand. ”

Carl Turner's Notes

“I thought that it might be cool if I collected together some of the things I've come to worry about and/or understand which I think you might like to find out about too.”

Urs Schreiber's Notes

“The purpose of the nLab is to provide a public place where people can make notes about stuff. The purpose is not to make polished expositions of material; that is a happy by-product. We all make notes as we read papers, read books and doodle on pads of paper. The nLab is somewhere to put all those notes, and, incidentally, to make them available to others. Others might read them and add or polish them. But even if they don’t, it is still easier to link from them to other notes that you’ve made.”

Chris Hillman's Notes

“The purpose of these pages is to promote the appreciation and understanding of the special and general theories of relativity”

John Baez's Notes

“My introduction to blogging came in 1993 when I started an online column called “This Week’s Finds in Mathematical Physics”. The idea was to write summaries of papers I’d read and explain interesting ideas. I soon discovered that, when I made mistakes, readers would kindly correct them—and when I admitted I didn’t understand things, experts would appear from nowhere and help me out. Other math bloggers report similar results.”

Garrett Lisi's Notes

“Welcome to my brain, have fun looking around.”

Keith Conrad's Notes

“These were written up for various reasons: course handouts, notes to accompany a talk for a (mathematically) general audience, or for some other purpose that I have since forgotten.”

Deepen Your Understand - Writing down thoughts in a non-formal but structured way helps to understand things more clearly.
Help Others - The best way to learn is to read the notes of someone who wrote them down while he learned the topic.
Access Everywhere - When your physics notes are available online you can read and edit them anytime from everywhere.
Join the Community - For students publishing informal notes can be first step towards joining the scientific discourse.

“We all waste too much time with searching for mathematical information that is already out there. As a student, before the dawn of the internet, I wasted days in the library, on chasing references to the secrets of the universe. Now the internet exists, but we still waste time searching randomly. Things have not been connected. […] Sometimes I see people proudly show me their private maths notebooks. Too bad that only one single person is profiting from it. We are an army of wheel-reinventers. (That’s necessary to some extent for personal exercise, but we’ll get nowhere if every single person retraces every single step. That has ended being sensible several hundred years ago.)” From the description of the nLab by Urs Schreiber

“Feynman told us a few times to keep notebooks. When working on a hard problem, spend hours of concentrated time. People who don't think for hours without interruption cannot solve hard problems in his opinion. When you stop, try to save your mental state in the notebook. Learn to write notes that allow you to pick up your train of thought. In this way, days of sustained thought could be brought to bear on an extremely hard problem.” http://mentallandscape.com/Writings_Feynman.htm

“It often happens that two schoolboys can solve difficulties in their work for one another better than the master can. […] The fellow-pupil can help more than the master because he knows less. The difficulty we want him to explain is one he has recently met. The expert met it so long ago he has forgotten. He sees the whole subject, by now, in a different light that he cannot conceive what is really troubling the pupil; he sees a dozen other difficulties which ought to be troubling him but aren’t.” C. S. Lewis in Reflections on the Psalms

Teach obvious things. First, your peers will laugh that they already know. Later, they’ll link to your content to answer questions they get.Teaching forces you to break down your process into something that can be explained. When you do this, you'll understand it better yourself. Sean McCabe

Always remember: reading without writing is daydreaming and even if you're a student: The world needs your insights!
