Heh, well, I've got some time, so...

I never said they were a different unit (assuming you are talking to me cause i'm the only one that talked about degrees). Switching from Pi to Tau will only obscure it more. |
Uh, yes you did:
Someone is trying to replace PI cause fractions are hard to understand for beginners... There are already degrees for that. |
If you weren't saying that pi and/or fractions are redundant because degrees (different units) exist, then what were you saying?
Would love to see the US join the rest of the world and adopt the metric system before it's too late if it isn't already. |
Do you not understand that by adding this you specifically highlight your issue with units?
I only mentioned degrees because in the video he said that Tau makes it easier for beginners who don't know fractions by simplifying the fractional part such that the top value is always 1 and makes it a bit easier to tell if one radian (from the 4-5) is greater than the other. This isn't even really a significant benefit, for anyone other than beginners who have a hard time understanding how fractions work. ... |
I think you don't have a clue what you're talking about.
The whole point is that it makes more sense to beginners.
And it has nothing to do with understanding how fractions work.
It has
everything to do with making a 1:1 correlation between the fraction and the unit of measurement.
The main benefit of it being fraction is that when doing computations. If you have 1/3 for example. You now simply say your answer is 0.3333333 and that answer may be good for your calculator. When someone else needs to use the same result but they need more precision, if it was left in the form 1/3 then that person could simply calculate it to whatever digit they needed. |
You are arguing the utility of fractions vs decimal representations -- totally unrelated to the issue of pi vs tau.
Pi is a known quantity whose value can be calculated. |
Tau is also a known quantity that can be calculated. Oddly enough, as tau is twice pi, it is just as easy to calculate one as the other.
Changing from Pi to Tau would not benefit anyone, simply create a rift in knowledge of those that know Tau and those that only know Pi. |
That's a false dichotomy. You cannot learn one without learning the other.
There is no benefit here except maybe instead of first teaching students Degrees and ease them into Radians when they understand the concepts with degrees, they will instead use Tau. |
Wut? It seems to me that you are again conflating tau with some arbitrary numbering like radians.
If you are going to have to perform a conversion of some sort you'll have to do it no matter what. Having to perform conversions is not a valid argument against using pi/tau.
Human error is always a problem and not unique to using tau vs pi. This is a red herring argument.
What happened to "such things only obscure the mathematics more" |
Oh, a strawman! Thanks! (I've missed those!)
For people who know and understand pi/tau/whatever, it doesn't matter. The fact is the math works out the same no matter whether you write it as 2π or т. You seem very interested in ignoring the fact that
2π ≡ т
But as you are so well-versed with pi, why not just use it?
Your experience does not correlate with
observed learning behavior.
Now, if you had read the "manifesto" or any comment, you would see that the point of it all is
conceptual clarity. Oh, but wait,
I only skimmed through the longer video and it seemed... |
If you aren't going to bother reading/watching/understanding the arguments against yours, how do you really expect anyone to take your "rebuttals" seriously? Because then you'll say things like:
Actually it'll be worse cause i'd have to memorize a lot of the formulas with Tau. |
...which only goes to show you don't know what you are talking about.
The whole point of tau is that there is nothing (as in lists of formulas) to memorize.
The whole point, again, is pedagogical utility. It has no effect on extant literature, practice, or correctness. That's a pretty good plus.
Wow, sweet! I stand corrected.
I don't think it quite demolishes my argument that the cost of instantly metricating (funny word) is fiscally feasible. I do personally think it was a mistake for congress to vote on metrication without applying a deadline of some sort (and instead marking it as optional compliance).
I think that there should be a timeframe set to metricate. Ten, maybe twenty years. And it will happen.
I don't disagree, but you are arguing one side of the coin while discounting the validity of the other argument. Just as there are nice arguments against DST showing huge costs, there are nice arguments for DST showing savings.
I don't claim to know the answer. My personal opinion is that you ought to leave the clock alone and
behave differently as appropriate. (It is not unusual for people to change times of things outside of DST's effects.)
That isn't necessarily a complete argument against DST. It is, at least, an argument that people ought to be more careful about how they manage their industry during the change. What the argument has going for it is that capitalists don't care to do anything to make that one day safer for their
slaves employees.

My biggest problem with DST is the disruption it has on a persons circadian rhythm. |
Agreed. People who work in healthcare, for example, experience unpleasant circadian shifts on a regular basis -- and their is a documented correlation between sleep deprivation and mistakes made in healthcare.
The [correlation] between sleep deprivation and over-eating, weight gain and stress are pretty well documented. |
Yet, I think it probably that a week's worth of stress from "spring forward" is less significant than other regular stressors in people's lives. Blaming it all on the clocks doesn't strike me as a safe argument.

I've only got 3.14159265 memorized, though I should also have the 3589 memorized too... Alas.
Also, most people don't like it when others play with their names, so that's interesting.
I just bought my wife some tulips to plant in the front of the house. (She likes to keep the garden along the porch there.) Hopefully they will bloom all through the holiday.
Saint Valentines is a wonderfully morbid holiday too...
And, for fun,
