The eternal mathematical civil war between π and τ enthusiasts rages on. On the left, we have the elegant 2π and its variations, looking professional and composed. On the right, we have τ (tau) attempting to do π's job, resulting in awkward fractions and mathematical chaos.
For the uninitiated: τ equals 2π, which some mathematicians argue is more intuitive since a full circle is τ radians instead of 2π. But this meme suggests switching would be like replacing your reliable lab technician with a dinosaur trying to pipette samples. Some traditions exist for a reason.
