• Pi is wrong

I was born on the day of tau.
I wish I learned about this shit in math so I could understand it.
Video of female talking lots about stuff I don't understand. Female also in the kitchen making fresh pies. On the one hand, I have an erection. On the other, I want to give my screen a black eye.
i never learnt parabolae or trigonometry
She may have a point but I don't see how using tau would make trigonometry any simpler. She talks as if anyone who doesn't get trig will magically understand it when they start using tau. Yeah, right. It's not really any simpler. Besides, what exactly is so hard about memorising that 2pi = 1 full circle? You learn about pi and using it for calculating area and circumference of a circle way before you start doing trigonometry. By that time, measurement in radians should be a cakewalk to you.

If there was some really wrong with using pi, we would have stopped using it, but it certainly isn't hard to use so we keep using it.
The only thing good about the video were the drawings. Her logic could apply to degrees as well, since "why not make it a nice and even 100?" The concept of having pi=2pi could make sense for a bunch of kids who don't understand math and need the oversimplification, but it's already engraved in the math world. Example: The convention for electric current in a circuit is the exact opposite of what makes sense, when looking at the physics of it. Without getting too deep, the current is caused by moving electrons. These move from the - side to the + side. There's also the part where, you know, tau is used in rotational physics. Kind of throws a wrench in the equations when my symbols are both constant and variable That, and I dislike pie. [editline]16th March 2011[/editline] By the way, math is awesome. Still don't see why people don't take 300 level classes for fun
[QUOTE=superdinoman;28606535]Her knowledge of math is strangely erotic. I would like to put my penis in her[/QUOTE] Post this on the video, and everyone who rated agree up or funny. Thumbs up his comment, we will make it the highest rated comment.
There are several of these mathematical / physics related laws that could use optimization. But are so integrated in human society that it's nigh impossible, let alone cost efficient, to adopt.
I'm reading everything wrong. Anyway, I never understood why we need a term "diameter". It's interconnected with the radius, and I've only ever seen diameter used in one equation, which is circumference = pi * d
Ugh, I had to memorize the unit circle in my analysis class. I did better at trigonometry than what I'm covering now though.
Just finished with trig, fuckin' a I wish we used this.
Where the fuck in life I'll use trig
I feel left out because I have a really hard time understanding math :saddowns:

I didn't understand anything. But now I want some pie.

I just asked my trig teacher about tau. He didn't know a thing about it. So, I just explained it as Tau=360 degrees. He was confused.
The pie making part was awesome, I LIKE PIE!
[QUOTE=ChrisDom;28655259]I just asked my trig teacher about tau. He didn't know a thing about it. So, I just explained it as Tau=360 degrees. He was confused.[/QUOTE] Tau isn't 360 degrees, it's 2*pi.
[QUOTE=JohnnyMo1;28656790]Tau isn't 360 degrees, it's 2*pi.[/QUOTE] I think he got confused with the conversion from deg/rads by 180/π so double them and you have 360/2π and 2π is Tau?
Even if he said tau was 2*pi radians he'd be wrong. Tau is dimensionless.
Angles are dimensionless.
[QUOTE=ThePuska;28660763]Angles are dimensionless.[/QUOTE] They have psuedo-units [editline]17th March 2011[/editline] Well, radians at least. When using them in physics, they start behaving like that
I prefer Tao. [img]http://interacc.typepad.com/.a/6a01053596fb28970c0133ecb045c6970b-pi[/img]
[QUOTE=ThePuska;28660763]Angles are dimensionless.[/QUOTE] Technically. [editline]17th March 2011[/editline] but it's hard to argue that that's practically true. You can't say there are 2*pi in a circle.
I feel bad because I understood this shit. Never had problems with Pi, though.
