This is the first of many love declarations and mentions EMBII makes of his partner Chiharu! This came just one day afte the very first uploads of the system.

My Dearest Chiharu....I Love you more. <3 Eric
Note that she's Japanese and not really bond, it's hair dye.

My oldest daugher moves into the dorms tomorrow morning. Dear Mady, You are forever my baby. <3 Pa
EMBII's daughter, Maddy Bobby, (presumably not with Chiharu) is going off to college! Sadface.

TODO actual Italy? Or some place named Italy in the US? One of the photos is from the First Lutheran church in Fargo, Nort Dacota.

In loving memory of Loraine Elizabeth White
EMBII's mum died :-(
Cost: ~0.001 BTC ~ $0.80 at the time.

I was dealing with severe depression brought about by life and the loss of my mom
was too many things left unsaid

This one gives Chiharu's full identity with picture basically. Message:
The Sato Family Arrives from Japan! Taken Aug 2. 2014 in Minneapolis MN. (Keiko, Chiharu, Hideaki, Katsuhiko) Now preparing for the Sato / Bobby Great American Vacation!!
so presumably Chiharu's full name is Chiharu Sato.

Parallel light by Ciro Santilli 40 Updated 2025-07-16
Often just called collimated light due to the collimator being the main procedure to obtain it.
However, you move very far away from the source, e.g. the Sun, you also get essentially parallel light.

Subsidiary of Carl Zeiss AG and also part owned by ASML, sole optics vendor of ASML as of 2020.
Exactly 1033 somatic cells on male, 959 on hermaphrodite, every time, counted as of 2020. A beauty.
Exactly 131 commit apoptosis in the hermaphrodite.
www.wormatlas.org/celllineages.html contains the full lineage as some huge and impossible to view images. This image was taken directly from The embryonic cell lineage of the nematode Caenorhabditis elegans where it is split across many pages, it is a thing of beauty on the PDF.
www.wormatlas.org/celllistsulston.htm contains a non-hierarchical table with the cells and their names.

If you pass parallel light.
For a biconvex spherical lens, it is given by:

We will sometimes just write them without superscript, as it saves typing and is useless.
The principal quantum number thing fully determining energy is only true for the hydrogen emission spectrum for which we can solve the Schrödinger equation explicitly.
For other atoms with more than one electron, the orbital names are just a very good approximation/perturbation, as we don't have an explicit solution. And the internal electrons do change energy levels.
Note however that due to the more complex effect of the Lamb shift from QED, there is actually a very small 2p/2s shift even in hydrogen.
Looking at the energy level of the Schrödinger equation solution for the hydrogen atom, you would guess that for multi-electron atoms that only the principal quantum number would matter, azimuthal quantum number getting filled randomly.
However, orbitals energies for large atoms don't increase in energy like those of hydrogen due to electron-electron interactions.
In particular, the following would not be naively expected:

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
