To be or not to be: 3 metaphysical conundrums.

As a voluntary assignment addressed to my students in our 1º de Bachillerato, here you'll find three stories, three strange cases about beings and non-beings, about concrete and abstract things, or about how things' properties depend on the observer's point of view.

Firstly, the links to the stories:

1. Train Cancelled.
2. The Hidden Statue.
3. Poincaré's Problem.


Now the links to the tasks:

a) Train Cancelled.
b) The Hidden Statue.
c) Poincaré's Problem.

They might improve your marks up to 0.8 points (0.3 + 0.3 + 0.2) at the end of this term. You are even allowed to answer the questions partially. Take your time and try to be both creative and thoughtful. Good luck!

Deadline: Tuesday, April 30.
