This document contains Maxwell's equations, which describe how electric and magnetic fields are generated and altered by each other and by charges and currents. It includes equations for the divergence of the electric flux density D and magnetic flux density B, as well as the curl of the electric field E and magnetic field H, related to charge density ρ and current density j. It also notes boundary conditions for the tangential electric field.
The document contains several equations from electromagnetism. It states that the divergence of the magnetic field B is equal to 0, and the divergence of the electric displacement field D is equal to the charge density ρ. It also contains two Maxwell's equations - that the curl of the electric field E plus the partial derivative of the magnetic field B with respect to time is equal to 0, and that the curl of the magnetic field H plus the partial derivative of the electric displacement field D with respect to time is equal to the current density j.
This document is a log of various dates and events from 1981 to 2008. It includes dates ranging from 1981 to 2008 with notes on events each year. It also lists social media and websites frequented from 2008 to the present day along with logs of conferences and meetings attended between 2008 and 2011.
The document discusses a conference that will be held on February 10, 2008. The conference will last for 4 days from the 10th to the 13th. It will take place at a PC near a train station that is a 1 hour 30 minute ride away from Tokyo by train. The document provides a website for more information about the conference.
The document discusses live streaming video services including Ustream.tv and nicovideo, which allow users to broadcast and watch live video over the internet. Ustream is a popular live streaming platform that can be used to broadcast events and share live video on the web.
This document contains notes from Daichi Obinata dated between June 13, 2009 and November 7, 2009. It includes details about his work experience from 1998-2008, programming skills and interests, and participation in various online chat communities. It also documents several nature photography expeditions between 2008-2009 where he recorded plant and animal sightings. Meeting notes are included from a conference he attended in November 2009.
This document contains symbols and special characters without any clear words or sentences. It does not convey any discernible information that can be summarized in 3 sentences or less.
The document discusses a chat log from March 2008 about JavaScript, PHP, Perl and web technologies. It also mentions several conferences and meetups happening between June 2008 to April 2009 on topics like IT, Linux, OpenID and more. Names of individuals like yokochie, torricelli and sites like devlog.holy-grail.jp are also referenced. The document appears to be notes from an individual documenting conversations and events in the Japanese technical community from 2008 to early 2009.
This document discusses mathematical concepts including sets, natural numbers, and properties of addition. It defines several terms, like e belonging to the set of natural numbers N, and x and x' also belonging to N. It proves properties of addition like x + y = x + y, commutativity, and that e' + e' = e''. It also discusses representations of natural numbers in different numbering systems.
