Preface. Here is an relatively easy one, as compared to the previous part. We already found out when, let's find out where.
Background. Professor Swannie Taco is a genius in most fields of science and technology. She is probably hated by her parents, and her name is a perfect evidence. After Swannie went missing a few months ago, strange letters from her kept appearing on her G+ account. Nobody knows who exactly post these messages, nor understand the content of these seemingly cryptic memo.
1. For this particular puzzle, the only information required to solve it is the post.
2. Although not strictly needed, knowing high school math will aid solving this puzzle.
I really don't think any hints are needed for this puzzle. This statement itself is not a hint in disguise.
Overview. Knowing when the doomsday is, we need to know where and how. Luckily, she told the whole world how, now we just need to know where. If only it was that
Post. Someone once told everyone that imaginary powers could sometime be real. Maybe if I could attempt to walk across all platform once and only once, thus performing a magical feat, I could break his claim, while justify his claim at the same time... Let's just say such a paradox shall distort the world, and it shall be where everything begins to end...
Task. Figure out where she is going to execute her doomsday plan. Edit. Since this was too easy, I will accept the answer that make sense of the whole "riddle".
