# I'm 2nd year and we
get to play with Lasers and Li. Ni2. Great fun. Until you're looking at a diffraction pattern for the 80th fucking time.

Calm. Think calm.

# What sort of diffraction patterns?
I did a project on nanosphere array diffraction patterns last year. That was quite good fun, until the lab tech fobbed my off with non spherical non-self-assembling lypodium spores.

# Really, really boring ones
Looking at the fraunhofer and fresnel case for single, broad and double slits. Relating them to the Fresnel Integrals and the Cornu Spiral (with this magic unitless thingy, v). Finding the wavelength of our laser from them, all that kinda shit.

# Bummer.
I ended up sleeping a terms worth of labs away in the optics laboratory. ^_^

# Yeah
Last Thursday, from a piece of A5 paper, we made a loop big enough for both of us to walk through. It fitted over the door.

We tried diffracting through it but it didn't do anything.

Then I had some coffee. Then I fell asleep. Then I broke some optics stuff.

Next week we're doing something random to do with working out the speed of sound by making a box go ping.
