Croquet @ Oxford...

Was Great!

Had great fun punting, and learning to play Croquet.

Great time talking with Alex and Omega, two brilliant mathmos who are also very much into physics!

Interesting to walk around Oxford, and see a Trinity College which Isaac Newton didn't come from, and a Jesus which is hidden along a little alleyway in the middle of the city, instead of being tucked away up north and having it's own huge grass patch.

Also feels quite liberating to have larger roads and canals! Though that meant that the part of the river we punted on was quite forested... Which proved to be quite hazardous.

Gained an insight on what it meant for something like an electron to have a half spin on way there from Alex. Demonstrated it by rotating his hand 360 degrees to find his wrist in the wrong position, and rotated it another 360 degrees to it's original orientation! Also explained it more mathematically - "(Spin half is a result of)An accidental homomorphism between two lower dimension groups". Apparently it has to do with Lie Groups... SO(3), SU(2), U(2) and groups of that like.
