Another session at the Museum of the Histoy of Science, drawing objects through a microscope, and then monoprinting. It comes out in mirror image, and as I tried to write the ‘q’ of mosquito a sudden high pitched whining noise disturbed me.

Another interesting talk at the Oxford Skeptics in the Pub meeting — Mark Lynas is an eco-activist who came to the conclusion that GMO is not necessarily bad, and that Organic isn’t necessarily good, using the power of critical thinking. One interesting point he made is that the degree of scientific consensus supporting GMO safety is roughly the same as that supporting climate change. So if you think critically you have to accept both (or possibly neither?)

GMO - destruction of crops
Science support for climate change = science support for GMO saftey

Plea: be an activist on critical thinking.
The very energetic and interesting Dr. Helen Czerski presented “We need to Talk about Physics” at today’s meeting of Oxford Skeptics in the Pub. We learnt why blueberry jam isn’t blue; why the Hubble telescope is like a raw egg; and why there is a lot of physics still to do to understand everyday phenomena (such as how bubbles move in a turbulent fluid.)
I’m afraid the likeness is worse than usual. Dr. Czerski doesn’t do standing still.

Itchy is just being himself today. I feel rather sorry for Knee, but what can you do?
2. Itchy eats his pillow with gusto.
3. Knee: "Itchy! Why are you eating your pillow?"
4. Itchy: "BECAUSE, Knee, I keep forgetting things."
5. Knee: "Itchy! You're eating..."
6. Knee (face-palms): "Memory foam."
I have no idea if this is a universal joke or not. It works in the UK. At least, I hope it does.
Knee: "Itchy ... why is there a house brick in the filter jug?"
Itchy: "BECAUSE, Knee, it's to save water, OBVIOUSLY."
Another tale almost-from-life, and another experiment with watercolouring. I think the grain on this particular paper is too heavy for this kind of thing.
2. Knee: Hey itchy! Will you be long in the bath?
3. Itchy: I'll have you know, Knee, I'm REPAIRING the enamel [holds out a tube of Enamel Fix]
4. Knee [examining the tube]: Itchy! This is toothpaste!
Today Karen and I participated in an event in our local museum of the history of science. We drew pictures of insects seen through a microscope, and then transferred our drawings into monoprint. That’s my* body louse, Pediculus humanus, reproduced above – I forgot to reverse the caption. The event was designed to celebrate the famous work Micrographia, by Robert Hooke.
* only borrowed. I wasn’t allowed to keep her.
