You are a fucking lunatic. For real.
Since you asked (spoilered for length):
Spoiler:
Title reflects the fact that slide rules are just part of a the whole range of paleotechnologies which are dead or dying because of progress and rational laziness. Film is an example of a current technology that is rapidly becoming a paleotechnology and will be one once the current generation of Filmmakers who still use Film are replaced by the kids in USC Film School who will likely shoot 100% or 99% on digital. Examples of other paleotechnologies (that I happen to be interested in) include the printing press, typewriter, steam trains and chromolithography.
With respect specifically to slide rules - folks still don't get the connection between slide rules and math education
Here is a pertinent quote from the NPR slide rule thread:
From the Tufte thread: Edward Tufte forum: Analog clocks, sorobans, and slide rules[Slide rules] give you a visual that numeric values are NOT linear. The first 1/10 is 1.26 while the last 1/10 is 7.95...
In other words you get a visual representation that the percent difference at 1.2 to 1.3 is much larger than between 8.0 & 8.5
There's more of course - but the points are the same:Using a slide rule promotes two activities that the use of a calculator does not: one is that one must always have in mind what the answer to a simple mathematical problem means. The other is that the slide rule displays what the answer is not, as well as what it is.
1. Visual display of the number line in an intuitive manner.
2. Necessity of tracking the decimal point
3. Necessity for error checking.
Calculators can't check for GIGO problems and the nature of calculators means that the user is not forced to check, with slide rules after a computation you have to run a quick sanity check on the result (usually done by rounding the numbers you've multiplied/divided/involuted/evoluted/etc and estimating).
I collect them and use one when I can, but if I had a couple of million I'd make a couple hundred new slide rules to my ideal scale design.

You are a fucking lunatic. For real.
Taf is an idiot. You are mentally unable to comprehend that a 0.1 difference between 1.1 and 1.2 is a greater porportion of those numbers than 8.2 and 8.3? You need t see it on some archaic fucking tool?
Tad has bever dealt with logarithmic scales in excel? A slide rule is better for visualizing than excel, right?
Edit - a mod move this from science and technology, this device is old and archaic. My phone can shit out orders of magnitude more calculations per second than tad can do on his slide rule in a month.

Da fuck kind of calculus class allows calculators during exams? Let me guess: "Calculus for Business".
This thread rules.
I've also got a box of draftman tools that my grandfather had. All sorts of bizarre rulers.
Drafting tools are very cool - no clue how to use them beyond a compass for circles/arcs. I've been meaning to buy a set from ebay for a while, just keep getting distracted by other things.
Two big things missing from the list of paleotechnology are records (and record players) & vacuum tube technology - I have a miniscule record collection that I'd like to expand but haven't found the time. With respect to vacuum tubes, they are actually "coming back" a little because of things like vacuum tube power amplifiers just being better - a good example of an analog technology that couldn't be properly replaced by digital technology.
There is at least one non MIT or Caltech school that does not allow calculators. It is the school where I, somewhat recently, have taken Calc. I assure you it is not on any list of decent schools and yet calculators were not allowed. Only schools that allow calculators on math exams are schools offering shit math classes like the aforementioned "Calc for Business". Also, what exactly about Stewart's Calculus forces people to use calculators? It might be a bit computational heavy while lacking theoretical explanations but nothing in that book demands calculators.
You don't know what you're talking about:

Yes tad because every calculus class follows a text book in its entirety and every teacher/professor assigns all sample problems in the entire text book
Who is going to be our first abacus hipster? "I only use technology that pre-dates Christ"
Tad is bringing up Stewarts Calculus because that is one of the more common textbooks used. However, just because there are a couple of questions that ask you to use CAS to solve, does not mean that every single question requires same to solve it. Furthermore, none of these questions are ever on the tests in any semi shitty or better math class.
Tad you see how the number of the exercises says 57-58? What is required to solve the other 50 or so questions? Any CAS involved there?
Anyone recommend a good sundial repair guy?
Dude, there are hundreds and hundreds of graphing questions early on and hundreds and hundreds of CAS questions later. Stewart even has a little graphic for it.
Some perspective:
AP Calculus AB Calculator Policy
@Joeboo - Unfortunately, it may be a while. Abaci don't really count as paleotechnology because they are still in heavy use in China and never went out of production like the slide rule, vacuum tubes, mentioned above.The use of a graphing calculator is considered an integral part of the AP Calculus course, and is permissible on parts of the AP Calculus Exams. Students should use this technology on a regular basis so that they become adept at using their graphing calculators. Students should also have experience with the basic paper-and-pencil techniques of calculus and be able to apply them when technological tools are unavailable or inappropriate.
Graphing Calculator Capabilities for the Exams
The committee develops exams based on the assumption that all students have access to four basic calculator capabilities used extensively in calculus. A graphing calculator appropriate for use on the exams is expected to have the built-in capability to:
•Plot the graph of a function within an arbitrary viewing window
•Find the zeros of functions (solve equations numerically)
•Numerically calculate the derivative of a function
•Numerically calculate the value of a definite integral
Nope. Better switch it out for an astrolabe.F2-astrolabe.jpg
Further quotes from that link:
Students should also have experience with the basic paper-and-pencil techniques of calculus and be able to apply them when technological tools are unavailable or inappropriateAnd a whole paragraph i dont feel like quoting explaining that you need to actually show the steps taken and the reasoning for your solution. Anyway, I was laughing at a college course requiring calculators, you linked some high school shit. Why?A graphing calculator is a powerful tool for exploration, but students must be cautioned that exploration is not a mathematical solution. Exploration with a graphing calculator can lead a student toward an analytical solution, and after a solution is found, a graphing calculator can often be used to check the reasonableness of the solution.
I got rid of my GPS unit and went back to sextant for navigation. It's one of the few things that requires no batteries, yet is loved by women.
I used that same textbook for Calc 1&2 in college and I wasn't allowed to use a calculator on any exams.
Last semester bro.
Then you guys are fucking geniuses and God bless you for that.
Me I don't have log tables memorized like you guys clearly do so when I get a word problem on (for example) Newton's Law of Cooling if we're say covering Exp Growth and Decay and it turns out that the k in dy/dt = ky = (ln (17/28))/70 (copying straight from Stewart's example here, RL) I unfortunately need to use a calculator to figure out k=-.01663. Them's the breaks, I guess.
But again, kudos to both of you for memorizing log tables.
Your professor actually makes you solve it once you get it into a form that can't be simplified any further?
Calculus for Business yo
Either your professor didn't make you solve word problems or you completely misunderstand me when I differentiated (pun intended)above between problems that required numerical solutions (which includes word problems) and problems that didn't (what's the second derivative of y= e^(x tan theta) * x^3 or whatever).

I just graduated with a BS in computer engineering last year. Every calculus course (1-3) would not allow calculators on exams. I was allowed them in Diff EQ's, but there was no point with the exception of doing some arithmetic for some balance problems. I also took a Numerical Analysis grad course where they weren't allowed even during the class sessions. Took advanced physics math (weird class) which was a lot of bullshit with advanced calculus and physics topics and were not allowed calculators either. My performance and analysis class for computing systems we weren't allowed. I learned not to use one.
I think if I pulled out a slide rule I'd get yelled at too. No one ever asked, there was no point.

So are you a fuckin reptilian or what dude?
Work smarter not harder.
My teachers made us not use calculators, fine whatever. In the real world that's not how it works. My boss doesn't come up to me and go "ok.. solve this complex algorithm... NO CALCULATORS ALLOWED LOL"
