where are we?

[db (martinez, ca.)]

Does anyone know about this? http://clustrmaps.com/products.htm

If Dave thinks it is safe (i would really hate to be the one who found a way to crash the site), would it be interesting to know where people reading this forum are? Another question is; could it be stuck somewhere to keep it out of the way because the free version has an ad banner.

We know where i am: Martinez is the center of the world, but where are all of you?

Hi all,

here is a question that I really wanted to ask for a long time, but without daring to do it.
Another thing which is also interesting to know about all of us here, is : "What's your job ?". I know if may be kind of inquisitive, but no one is obliged to answer.
In fact, more than the actual job, or the social level in society (correct ?), I think it would be interesting to know if someone is interested in calculators because he's a scientist, an engineer, or something like that, and then he uses one every day for his job, or if it's a hobby without any link with his job. (I apologize for my poor english writing, it's hawful !).

My answer to all of these questions and others asked before in the Forum :
I'm french, I live in the woods in a small village (which isn't the center of anything, but a nice region), I'm 40, I own 4 HP's (33C, 41C, 28S and 48GX), that I use quite every day (not the 4 at the same time :-) !) in my job, as a tehnician in car industry.
Hope it's interesting and will be followed.

Kind regards.

Hello Giancarlo!

According to Google Maps you do not live "along" the Adriatic Sea but, rather, "into" it :)

BTW: I spent one month in Fano in 1982 serving the Army

Greetings,

[Giancarlo (Italy)]

Hi Massimo.

Well, according to the current pollution level of the Adriatic, living "into" it would mean posting from heaven (or hell... >:-> ).

Actually, my house is just 2 hundred meters from the shore, so I *do* hope the global warming will restrain from dipping myself into the Adriatic :-(

Yes, Fano is just a 20 min. driving from where I live.

Best regards.

What a rich tradition in math and theoretical physics, you and Jean Michel have there in France! And to be in education, standing "on the shoulders" of so many great men and women!

I am on Mobile Bay, Eastern Shore, about 88.5W, 30.5N; or 1.5 East of New Orleans, Katrina's eastern boudary - got the reference to Orleans, Jean-Michel. Schooled at Tulane and University of New Orleans. Would like to visit your part of France someday.already been to Paris a few times.

Would like to get a few threads on Relativity, Quantum, String, etc., plus other "Theoreticl" thoughts - would be kind of selfih of me since I would have little to contribute beyond some some good questions. If "y'all" are interested maybe we could get some stimulating chatter in a new subject.

Hi, Richard --

---

• Texarkana, Texas and Arkansas

  Other examples of "border-straddling" twin cities:

• Kansas City (Missouri and Kansas)

• Bristol (Tennessee and Virginia)

  But here's a more intriguing example:

• Derby Line (Vermont, USA) and Stanstead (Quebec, Canada), featuring the border-straddling (by design) Haskell Free Library and Opera House
  

which is one of many "border oddities" between Canada and the US' New England region, which includes towns and even houses bisected by the border, which were platted or built prior to accurate surveying.

---

Er, yes, HP calculator-related content:

Click on the link for the Library and Opera House, and notice that the co-ordinates for Derby Line, Vermont is slightly north of 45 degrees North. I'd always assumed that the international border there was exactly 45 degrees. However, the Webster-Ashburton Treaty established the location 3/4 of a mile north of the line, so that a pre-existing U.S. fort would be on U.S. soil.

Convert the 45 degrees, 0 minutes, 20.81 seconds latitude of Derby Line to decimal using " 45.002081 ->HR ". Multiply the fractional part by 60 nautical miles per degree of latitude. Then, multiply by 1.15077714646 to obtain 0.39913 US statute miles, placing the Library and Opera House less than a half-mile north of the Derby Line location (presumably City Hall).

The ideal tool for this calculation is the HP-28C/S, with its fine units library with definitions and conversions. (Unfortunately, units cannot be attached to numbers, as with the HP-48/49/50.)

Regarding calcutions for surveying: If one does not wich to purchase specialized calculating software or tools, or the accessories for the HP-48/49/50 series, there are several less-expensive options:

• HP-71 5061-7238 Surveying ROM
  
• HP-41 Surveying Pac
  
• HP-65 Surveying Pac

In order of acquisition, I have HP35, 11C, 41CX, 38G (via eBay, I was faked out by the big "enter" key - thought it was RPN but it's algebraic!), 41C (via ebay), 32Sii, 42S, 48GX, and 33S (all acquired new except as noted). I used my Dad's 35 for 2 days straight to finish my thesis, then I had to get one of my own. I still use one of the 41's almost every day for both scientific and casual calculations.

Rats! While I was playing around with the Radio Shack EC-4004 (re-badged Casio fx-3600P) the original CR2025 cell finally went dead. I know for certain that I used it in 1988, and perhaps a few years before that, so that CR2025 lasted about 20 years. But I'll grant that it's seldom been turned on since I got my hands on the HP-28S.

Regards,
James

[James M. Prange (Michigan)]

PS:

For work, normally a 48SX, but occasionally a 48GX.

For "real work" at home (when I just want to get some calculating done with no nonsense), either a 48SX or 48GX, whichever one is easiest to reach.

For just playing around with, most often the 50g now, but sometimes the 49g+ or 49G.

The Sharp is "interesting" and powerful, but I rather object to switching between "calculator" mode for ordinary interactive calculating and "basic" mode for writing and running programs, and of course, in calculator mode, it's an algebraic model.

The Radio Shack is interesting and powerful too, even though it's algebraic, and writing programs for it can be rather a challenge, but I'm often amazed at how much can be accomplished in just 38 program steps (but some things, such as storing a number into a constants register, count as only 1 program step, not 3 as might be expected).

The Lloyds is just a simple 8-digit 4-banger plus square root, %, +/-, and a memory register, but it's my oldest still-working calculator, and it still works with the original battery from about 1980.

I overlooked at least one, even though it's often in my shirt pocket, a Radio Shack EC-232. This is a thin solar-powered "credit card-sized" 4-banger with a membrane keypad. It's a pain in the neck to use, but the nice thing about it is that it fits in my shirt pocket so comfortably.

Giancarlo,

This is GREAT! Thanks for all the work.

I second Valentin's suggestion that this somehow become a quick intro to the denizens of the forum.

Is there some way to make this updatable by each of us so you don't have to do all the work? (Probably not - somebody will trash it!) Actually, once the initial work is done, it might not be too much work to add new folks as they send you their details.

I would suggest instead of age (which changes!) that year of birth be used.

Maybe also a column for number/brands of calculators (like the recent round of such info) as well as a column for favorite(s).

PS for the current table, I'm 61.

[Valentin Albillo]

Hi, Giancarlo:

Giancarlo posted (the underlining is mine):

"A new update including some suggestions (still compiling tghe list for owned calcs :-)"
I think that it should be calcs actually used at work rather than owned calcs. At least that is what was originally asked, and the first posters replied to that, myself included: obviously I do have 70 calcs, but the only one I use at work is Emu71.

This would be much more interesting and IMHO preferable to a long list of calculators in everyone's collection. As the jobs are being included too, it's far more relevant and interesting to know that an astronomer, say, still uses an HP-41CX for work, than to know that he owns precisely such, and such, and such, and ... vintage calcs.

Also, if at all possible, sort the list. It's very easy to do using a great variety of tools and applications, but all failing, issuing a simple SORT command in an MS-DOS box under Windows, like this:

      SORT  <  inputlist.txt  >  sortedlist.txt

say (or a variant), will do the work.


Thanks a lot for your efforts and

Mobile Bay is in Alabama - I went to college in New Orleans.

Retired from the computer business: IBM, REI, ITEL. STARTED WITH THE TI 59, my first programmable about 1975. First programs for demonstrations in the field included financial and operations analysis deriving workload projections using learning curves and ques based on reliability statistics for various equipment installed. Other uses of the hp line included statistical analysis in market research (mostly before laptops with significant storage). Now using the hp50g in my retirement as a hobby: projecting value of timber harvests, photography in such things as depth of field calculations, etc. and current pet is catching up on readings in theoretical physics.

Cities lived in during working career: Birmingham, Al, Anniston, Al, Huntsville, Al, New Orleans, La, Dallas, Tx, Frankfurt, Germany, Chicago, Il, Washington, DC, Los Angeles, Ca, San Fancisco Bay area, Ca, Pensacola, Fl, Tryon, N.C., Montgomery, Al, and finally in Fairhope, AL, a neat village on the eastern shore of Mobile Bay. Reminds me much of the village of Carmel, California and the string of villages between San Francisco and San Jose: Palo Alto, Mountain View, Saratoga, Los Gatos, to name only a few. As Director of Product Assurance, I enjoyed the opportunity to live in Cupertino just a few blocks from HP.

Agriculture: My wife & I raise wheat, cattle and a small band of sheep. I live in Central Montana....closest neighbor is 5 miles (getting a little crowded, maybe time to think about moving) I have 3 or 4 41's and a load of 10B's and a 19B11. My work with calculators is nearly all finance. Definitely not high finance. Still use my 41C I bought in 1979. Still have my HP 85 I bought from Educalc in about 1980-82?

I feel like a square peg in a round hole on this forum with all you engineer types.

[Jim Creybohm]

Don:

Went to School of Mines in Butte, and also ordered my 41CX from Educalc in '82 or 83. I remember being wowed as UPS delivered it in only 4 days! To my door!

I think the cost was around 250 USD. What I wouldn't give to have Educalc around today....

Still travel down annually to Anaconda to golf Old Works.

[JDonley]

Hi Jim;

Sounds like we have alot in common. I was raised around the oil patch on the gulf coast of Texas in the 40's and early 50's. Spent a little time in the late 60's and early 70's buying oil & gas leases in the Powder River basin......didn't make any money. Am not a cat wrangler, but do have a 3 year old cocker spaniel who takes me for a long walk every day. And I have spent many days horseback in my younger years. Wanted to go to school at Colorado school of mines, but ended up at Denver University instead. Am not a golfer however.

I hate to be the geek to point this out, but you can't reliably find a person's year of birth by subtracting their age from the current year! I'm 42 but I was born in 1964.

[Giancarlo (Italy)]

Thomas,

I got the point, but I had to make some assumptions because I had "mixed" figures (some years of birth and some ages).

However you and any other please feel free to point out any amendment you'd like to see

and I'll be glad to update the table accordingly :-)

Thank you and best regards.

As Garrison Keillor once said; "ask a question, get an answer". In this instance; the answers were better than my question.

To Anntoine M. Couëtte: Ah, but Martinez is the center of the surface of the world. No place on earth is farther than 180 degrees around the spheroid from us. While this can be claimed by any other place, i thought of it first. "I leave the proof of this as an exercise for the reader".

To Giancarlo: You did a great job on that database. Next time one of life's riddles rears it's head; i'm calling you. The blank info for me is 1955, Surveyor & Licensed Engineering Contractor, 41cx.

...but since the Earth is flattened at the poles, the North Pole has a better claim to be the center of the surface of the Earth. And if you limit your possible destinations to dry land, you'd probably have to pick a spot somewhere in the Middle East. (Update: Egypt, actually.) (Another update: Turkey, actually -- I should have read that web page more carefully the first time around!)

It's all moot, anyway. Everybody knows New York is the center of the universe. ;-)
