HP 12C in Hemispheres Magazine



The HP 12C is mentioned in the Updates section of the April 2007 United Airlines Hemispheres magazine.

"Celebrating the Tool / Possibly the most seminal invention in accounting since the W-2 form, the Hewlett-Packard 12c financial calculator has been around since the year that DeLorean Motor Company delivered its first automobile. To celebrate 25 successful tax seasons, HP released a limited edition of the 12c that brings with it five modes, a 400-step memory capacity, and tools for amortization, bond yield calculation, cash-flow analysis, and depreciation. A 25th-anniversary edition DeLorean might drive faster and a 25th-anniversary edition of Blade Runner would certainly offer more excitement, but having endured Reagan, Clinton, and both Bush administrations, the 12c financial calculator has proved its staying power. $79.99; hp.com"


I don't think you can copy the text, since, my guess, you don't have the copyright for it. Mentioning the link and putting your own comments are fine.

Actually, short quotes such as this one are permitted without violating copyright. A link was also provided, so this would not be a problem.

You can quote a few sentences, but not pages worth of material and be ok.


Most publications state a specific word-count limit for quotes or excerpts. I found no detailed guidelines at the following sub-link:


I seriously doubt that United Airlines would make an issue about something of this nature. It amounts to free advertising at no cost for the publisher, or any undeserved benefit to the quoter.

Come down to earth, Namir, don't exaggerate. Capitals plus 3 exclamation marks for such a small quotation ... I tend to second Karl in this matter.

I'll see how you react when someone copies from your own work without permission.


That was your stuff? Go figure.

Yes, well, we know that inflight magazines are particular targets of copyright abuse. There must be somehing about the cabin pressure at 35,000 feet that just turns ordinarily law-abiding travellers into rapacious, file-trading, market-hating pirates!

Either that, or it's all the iPods up there..




I don't write for airlines. So it's not my stuff. But I have written many books and yes deem copying and pasting just like that, with no permission, to be wrong.

The links the other folks provided don't really represent references to US government websites on copyright laws. I take what Wikipedia says with a grain of salt!



This link may help everyone:


IOW, it is a grey area and in the context of this thread everyone may be right.

I'll risk the wrath of the Copyright office and provide a few quotes:

"...examples of activities that courts have regarded as fair use:...summary of an address or article, with brief quotations, in a news report..."

"The safest course is always to get permission from the copyright owner before using copyrighted material."

Interestingly, Google has no problem with leveraging fair use, type:

Hewlett-Packard 12c site:hemispheresmagazine.com from google.com, then click cashed.

Also interesting is the legal notice: http://www.hemispheresmagazine.com/legal.html

Or, more to the point, the tests for infringement are as follows (this is excerpted from the link http://www.copyright.gov/fls/fl102.html):

1. the purpose and character of the use, including
whether such use is of commercial nature or is for
nonprofit educational purposes;

2. the nature of the copyrighted work;

3. amount and substantiality of the portion used in
relation to the copyrighted work as a whole; and

4. the effect of the use upon the potential market for
or value of the copyrighted work.

Now look at each test in the context of the disputed quotation.

1. Purpose and character: clearly not commercial.

2. Nature of work: a review in teh context of advertising

3. amount and substantiality: Well, it is the whole text of one subject of a multi-subject advertising review. So it is substantial, but again based on the other three tests, there is no harm.

4. Effect on value: clearly not negative. The quotation
brings in more business than it destroys. In fact it destroys nothing.




I think the link is more than enough to take anyone who is curious to read the original text. The copying was not necessary to inform us.


Links are not forever, and there is no warranty that the publisher will keep an inflight magazine issue online forever (it has bandwidth and storage costs to consider, among other things).

So perhaps, when in the future someone tries to take a look to HP12C advertisements (something many people here does, looking for 1970 ads), he/she will just find a broken link.

A quotation will be sort of a fossil, a small clue of how things were...

IMHO this case doesn't amount to a copyright violation.


Yes you can, but you got to change the font!


Citing with mentioning the source is no problem, not even in the USA 8)
Posting whole chapters would be a different thing though.


To abandon reason on the alter of a pure idea is likely to be inherently destructive. We live in an age where intellectual property is reaching dangerous extremes. Chemical, agricultural, and medical corporations are seeking to copyright the very substances of life. If a patented seed by chance blows onto a farmer's land, germinates, and bears fruit, the farmer is then, according to current law, financially beholden to the corporation holding the patent, even though no action in violation of patent law was taken by him. Disney got it's start by introducing Mickey Mouse in a cartoon parodying a popular film of the day, in other words, via a derivative work. Today such actions are the subject of lawsuits, to the detriment of our cultural enrichment. Intellectual property deserves its due respect and protection under the law, but I can only hope that in the course of time our grasping, possessive, and greedy nature does not bankrupt our culture in the feverish pursuit of its autocratic ends.


I do find the debate interesting. After reading the fine comments left by folks that I do respect, I will say that I did overreact. Having written many books I am (over?) sensitive to casual quoting.



Can we quote you on that?



It's right there big as day <wide grin> ... maybe I should have used bigger fonts if that was even possible??? And when the link is gone ... it's gone and we can go back bashing "the" auction site, and so and so calculator-auction sellers, and answering questions about how to switch comma radixes to decimals on the physical HP-15C calculators, and so on!!

Talk about shooting myself in the foot!!!!

HELP!! I need the distraction of a good math challenge that would even keep a Cray computer busy!!

<laughing hard>

are you listening? :-)

Best regards.



"HELP!! I need the distraction of a good math challenge that would even keep a Cray computer busy!!"

Namir, if you need a math challenge use this link to find the problems from the 1985 - 2006 Putnam Competitions:







I meant I need the challenge for "others" to get busy (said with tongue and cheeks). As for me I am always looking at different kinds of algorithms.



Here are some funny numerical questions, not the caliber of VA's stuff but you could try it :

1. What is the interval of definition of log(abs(tg(355/(226+x))) ?

2. find the solutions of : 0 = x^2/30 + 0.99*sin(7*x)

3. Calculate the first 100 terms of : U0=1, U1=1,


4. Find the square triangle (english?) with integer sides, minimal perimeter, and maximal area, that area being less than 1000.

Questions like this show how graphical calculators allow us to "see" solutions manually. Enjoy.


OK, here is :

1. All reals apart from the interval ]1,9190491358E-05 to 1,9190491414E-05[ on my example of machine, depends on precision thereof (the better, the smaller).

2. typing error, I must check.

3. Graphs as a series of strange segments heavily depending on calculator precision

4. sides are 23, 60 and 68

Granted, not very exciting...


This shows greatness, Namir. My respect for you.


Thank you Geir!!

<bow down>

That's OK Namir, so did I!

Well things did not get out of hand and no one lost their cool. Just an honest discussion.



Actually, the [head] tag

will let you shout

in one large font. But as you can see, it sets off the "loud" text on a line by itself. Not that I would encourage anyone to

shout unnecessarily!!

you understand. 8)
