Algebraic Topology

Today (and yesterday) John and I have spent many hours desperately slogging our way through the Algebraic Topology homework, which consisted of many proofs about degree theory. Some proofs were easy and some were... well.. didn't fall out so nicely. The one we seemed to get very dirty with was showing that the degree of a reflection in a hyperplane was -1. In the end we "did it" using a suspension of the reflection map. I believe it...

And now it is back to MAPLE. I hate the collect function in MAPLE. It won't do what I want it to namely collect together products of variables. This is most infuriating and I have had to completely rethink my plan of attack.

I really want to see a guinea pig sneeze. Wouldn't that be adorable?!

In fact, I just searched for it on YouTube. And unsurprisingly there are videos of Guinea Pigs sneezing.. I suppose this will be the activity for the rest of the evening.. to systematically work my way through them!
