For now, I think the preferred Periodic Table is the one available from APH. It’s one of those things that does not need to be newly invented each time it appears in a textbook. An effort is being made to determine the best way to present the Table, and there may be more options in the future.
I apologize for not responding to your question earlier.
I have never seen that symbol before and I don’t believe there is a Code symbol for it. My suggestion would be to create a shape (such as [braille]$tv) and define it as “two lines in a plane cut by a transversal”. Depending on how often it is used, you would either place the tn at the site, or list it on the special symbols page.
I checked with a real math person and she said that it would not be necessary to indicate the color or the ovals around the columns (since the ovals encompass the entire column). However, the arrows should be drawn tactiley.
According to Braille Formats the alphabetic page numbers go on the line immediately following the running head (line 2). So if you are transcribing for 1st grade, the extra blank line would make it appear on line 3.
In [u]abbreviations[/u] and Roman numerals, the effect of a double capitalization indicator extends to all the letters that follow, but a symbol other than a letter terminates its effect. In abbreviations, the double cap would end at a hyphen. Rule III sec. 22b
This rule does not apply to hyphenated compound words. The effectiveness of the double cap would extend through the hyphen. Could you cite the reference that says “a symbol other than a letter or a hyphen terminates its effect”?
Thank you so much for the explanation, and please thank your “favorite Physics teacher” for me too.
PattyHi. I have been asked to give my opinion on the topic of the use of the Nemeth asterisk as a multiplication sign in a 3rd grade workbook.
As far as I know, Promising Practices (guidelines for K-3 braille materials) does not address this.
As a braille transcriber, we are to braille what we see, following rules in the Nemeth Codebook and the BANA 2007 Update.
Certainly if this workbook is being brailled for production, you would not change the asterisk to a multiplication dot.
If, on the other hand, you are (or are working for) a Teacher of the Visually Impaired and are producing the workbook for a specific student and *only for that student, and the teacher has expressly asked you to use the multiplication dot instead of the asterisk, I would follow the teacher’s request. HOWEVER, this is not Code, and should not be common practice.
PLEASE NOTE: The asterisk is used as the multiplication symbol when students are using a calculator. The asterisk is the symbol on the calculator keypad, and that is the symbol we braille, using NC keystroke notation. I would not change the asterisk to a multiplication dot in exercises that are meant for calculator practice.Lindy Walton
This should work out just fine if you use the words supplied in the chart. I would include a transcriber’s note stating
the following:
(TN) The chart is brailled as a list. The English letter equivalent is followed by the hieroglypic label.A Eagle (1)
A Arm (2)
B Foot (3)
etc.If a puzzle follows, I would include the numeral in parentheses with each hieroglyph name; that will make it easier for the student to locate the item since the hieroglyphics are not in English alphabetical order.

Thank you for this fine question. I have asked my favorite Physics teacher who says emphatically that this is an English letter “v” used in the physics of motion.
Do not italicize these letters in braille.
Please note that the lower-case Greek nu *is used to denote “frequency” in the physics of wavelengths.Lindy Walton (answering for Dorothy)
Hi Laura.
The ellipsis must be spaced (see NC Sec.43b)
Braille the entire numeral, then one blank cell, then the ellipsis.As for your curiosity question, I have asked my favorite math teacher who says that
repeating decimals should have a horizontal bar (macron) over the repeating numeral/s.
He would interpret 2.46… as a rounded number, with additional digits not shown.Regardless, we braille what we see, following Nemeth Code spacing rules.
Thank you for your question.
