6:47 - ETC here stands for the "Electronic Toll Collection" system.

7:58 - Element 115, also known as UnUnPentium (which should, by all logic, just mean normal Pentium, but I guess they didn't want to be confused with the processor) is, uh, widely believed to allow for gravity field manipulation, or some such technobabble. Read up on it here.

8:09 - When the otaku says "the navy loves their boats," he's saying part of a mnemonic to help remember the elements of the first two rows of the periodic table. The mnemonic goes as follows:

Suihei ri-be boku no fune H He Li Be B C NO F Ne

It works, as long as you understand Japanese. The elements listed are Hydrogen, Helium, Lithium, Berylium, Boron, Carbon, Nitrogen, Oxygen, Fluorine, and Neon.

8:53 - The Kurofune were the black ships commanded by Commodore Perry (last seen in Dokuro) sent to open the borders of Japan. Your history lesson begins here.

18:35 - Tsukumogami are a pretty interesting bit of Japanese folklore, and well worth learning about if you're into that kind of stuff. Begin here, then read the Otogi Zoshi excerpts for some stories and neat art.

19:23 - Hyakki Yagyo (Hundred Demon Wondering in the Night) is a famous picture book of ghosts and sprits. The book edited ghosts that were believed to live in the nature of Japan over years and sprits that came from foreign countries such as a fox with nine tails. This book was published in the Edo era. People of the Edo era used to wonder around the world of myth such as sprit and hell through this kind of picture book and play. From the end of the Edo era and the beginning of the Meiji Era, Kawanabe Kyosei lively reproduced the world of the burning hell in a colored woodblock print, Nishikie, using fresh red color of blood. This tradition was passed on to the modern time, for example Mizuki Shigeru?fs Gegege no Kitaro and novels by Kyogoku Natsuhiko. Recent hits are novels, cartoons and movies Abeno Seimei who is a shaman who control sprits and devils. (Stolen from here.)
