My slide rule is also my dad's from grad school in the 50s. But for old school, nothing beats the pencil and paper method. Eight years ago we hosted a high school exchange student from central Asia - a country where students are drilled on doing math by hand. I was helping her with her AP chem homework and was amazed at how quickly she could do all of her calculations by hand, including taking logarithms. I still don't know how she did that. But it seem appropriate as the algorithm for doing calculations was formalized by central Asian mathmeticians and the world "algorithm" comes from "Kwarezm" - the oasis south of the Aral sea (or what's left of it).

How much can I sue my old math teacher for that told me I couldn't use a calculator because I wouldn't have one with me all the time?

Since we're on the subject of math, the word "algebra" is derived from Arabic, and the Moors were first to add the notion of zero to number systems. Alright, that was 500 years ago, more or less, but still. At that point in history they were way ahead of the dumb Europeans who were still stuck in the dark ages.

The best calculator I ever had was the HP scientific calculator I had in grad school. The best thing about it was it used Reverse Polish Notation. That way if anyone ever wanted to borrow my calculator I could say "sure, but you won't be able to figure out how to use it". I'm so glad my smart phone calculator app has an RPN mode.

my first calculator. 4 function. bought it on sale for $120 sometime in 1972-73 (how much is that in today's dollars?). i remember our college accounting instructor saying before tests "those that have calculators put them away cuz it wouldn't be fair to the students who can't afford to buy one." now they are a free app on phones, and if ya gotta buy one you can get a 4 function for a couple bucks. get off my lawn.

I worked on user-interface software for one of those IV pumps a few years ago at an outfit called Harvard Apparatus. Very similar tech is going into wearable insulin pumps as well. Big business with so many obese Americans.TrafficJam wrote:
I can add, subtract, multiply, and do fractions/proportions.
Seriously, you'd be surprised how much math is involved in weaving and knitting.
When I became a nurse, we had to calculate drip rates and medication dosages. Technology has made that skill obsolete. Now we have IV pumps with pre-loaded medication programs. For instance, if I hang an antibiotic, I type the name of the med then the rate, volume, etc. automatically comes up and I only have to push the start button.
Granted, this technology helps to prevent errors but are we becoming dumbed down from technology?
I believe we are. Originally the technology was supposed to make us more efficient and productive but it may be having the opposite affect.TrafficJam wrote:

I have an abacus and a K&E slide rule.
There are evidently different abacusi. Mine has 3 beads, a wood bar, and 5 beads. I noticed odd man out has one with 1 bead above the bar abacus.

yes. Mine is a Japanese style. I bought it in 1971 we I was living in Japan. At that time, all of the store cashiers had cash registers that would add up you purchase, print receipts, etc., but after doing all that, they would double check with an abacus. Calculating with an abacus (if you are proficient ) is much faster than with a calculator. But in this country, I one asked for a third of a lb of lunch meat at the deli counter. After failing twice I realized the employee had no clue what the decimal equivalent of one third wa. Ug.JimBlue wrote:

Originally the technology was supposed to make us more efficient and productive but it may be having the opposite affect.The latest thing I've noticed is stores where the person behind the cash register doesn't have to handle the coin part of your change. The coins automatically come down a slide on the machine and the cashier only handles the bills. My guess is that is because a lot of people can't figure out what change (coins) to give you even if the register tells them the amount.TrafficJam wrote:
