MODERATORS
24 hr vs 12 hr format is the most pointless debate of all time
π vs τ
(π is correct btw)
What's the area of a circle?
I have never seen this before, but one of the courses I have to develop curriculum for includes high school level trigonometry, and I am pretty fucking convinced that for learners (especially with LDs in math), the τ circle constant is conceptually easier to understand. The page is absolutely correct that showing a new learner the special angles with τ is a much simpler point of entry than the special angles relative to π (Figures 8 and 10).
Thanks for sharing!
A class full of young tauists sounds sick and I fully agree that it's conceptually much easier (simply by virtue of being the trivial definition). In application however pi still reigns supreme, so if they use calculators for instance there will be a constant translation effort (remember to multiply with 2, or was it halve it??) that could be frustrating.
You have the coolest job ever though much props
fuck
That's just Tau propaganda
Um, uh. WH40k!
I bow in honor to your arguments and flawless custom emoji usage. I'm a tauist, but you are a true sage of the Way!
🥰
thanks for sharing, I've never heard of this before but it does seem easier to understand intuitively.
24 hr is better but I'm forced to use 12 hr because everyone around me doesn't know 24 hr and the only people who do are military chuds.
Similar reason why I use mm/dd/yy for dates even though dd/mm/yy makes way more sense to me
I'm sorry but how do people not know? You just add numbers from 12. It's not that hard for most people, surely?
You would think, but in my experience you try to use 24 hr time and people suddenly can't comprehend numbers larger than 12, and its not worth explaining every time that 17:00 = 5pm. I just do the adjustment myself since 9/10 times they'll ask for clarification anyway
Mental arithmetic is in fact not universal. People who grew up on 24h time have the benefit of rote memorizing the relationship between 17 and 5 from childhood.
Like, the fact that 9:00 (or 21:00) points leftward / “west” with the hour-hand is something that kids just have to learn and remember. At first it is a lot of mental overhead. But I bet it was immediate for you when you read this, no?
