The most flippant answer I could give would probably be something like ‘What happens when a 15kW amplifier goes bang’, or ‘What liquid helium looks like when you accidentally spill some everywhere’, or just plain ‘ol ‘What a banana looks like in an MRI scanner…and in liquid nitrogen…and after you drop it on the floor, after it has been in liquid nitrogen’.
The slightly more serious answer is probably this: proof that my technique looks like it’s really going to work. I can image metabolism — the chemical reactions that go on inside all of us — in space, with a 2 mm x 2 mm in-plane resolution. This is really a big deal, and I’ll be telling other scientists about it soon, when I’ve got it to work properly.
Like Jack, I have some answers about liquid nitrogen, maybe just watch the video on my profile for that though.
I think the most exciting thing for me was that the resonant frequency of a drop on surface changes depending on what the surface is. This may sound like a really trivial thing and true, it’s not likely to revolutionise the world. But is was the first thing I discovered, and led to my first publication so it’s very important to me.
