These are a collection of notes that I felt are worth keeping to recall information whenever I need it as quickly as possible. The material in these notebooks is mostly of my interest without any intention of being useful for others. Of course, in one lifetime, I could be an expert in maybe nothing. So it may offend other experts, for which you have my sincere apology in advance.
The topics are very diverse, ranging from myths, witches, and giants to philosophy and physics. In other words, whatever I found amusing, beautiful, strange, outrageous, weird, or otherwise noteworthy; things I want to learn and a list of references related to my research.
The format of these notebooks is copied from Alex Reinhart and Cosma Shalizi. I will modify them later, but I am deeply grateful for these guys to come up with such a nice idea.
