I’ve noticed that when I say I don’t know something or don’t have an opinion on something (yet), there is sometimes a subtle push for me to make a strong claim anyway.

Noticing it makes it easier to resist it, but still, I wish the response was different. I wish people reinforced each other for refusing to speak uninformed.

Or sometimes not subtle. Recently a guy on twitter asked for my opinion about something and I said I don’t know enough to have an opinion. He kept saying “but you must have SOME opinion about it.” First of all, not necessarily. Second, yes, sometimes I have opinions that I realize aren’t based on any evidence. We all do. But what on earth is the point of sharing them?

That reminds me, Friday there will be the “Ask A Freethinker” Table at the university, and I’m excited.

I’m reminded because the one hour I attended my booth at clubs week, the person in the booth next to me asked me questions about morality and such.  She was some variety of Christian, not totally sure about evolution, and was so curious that she kept asking questions unprompted.

I really like being able to do these things.  And I just went through my books and found a few I want to bring.

Someone has asked me to explain how we can know which goals are morally right.  So that’ll probably become a blog post that I can refer everyone to if I get asked the question again…



When you need to manipulate and direct fluids in small volumes, microfluidic systems are the technology of choice.

Used by engineers, chemists and biotechnologists in applications from enzymatic and DNA analysis to the detection of pathogens to clinical diagnostic testing and synthetic chemistry, the tiny systems once required a clean room to create and thousands of dollars to manufacture. They also required numerous iterations to achieve the required complexity.

Sometimes called a “Lab-on-a-Chip,” the systems are now, through the work of USC researcher Krisna Bhargava, designed as 3D printable sets of building blocks which researchers can clip together in hours. The 1cc blocks can accomplish LOC functions like routing, mixing or analysis in three-dimensions. The researchers say a large share of the success in the fabrication process came as a result of recent advancements in high-resolution, 3D printing.

I just found out there’s a Federation of Calgary Communities, kind of neat, though it could be better.
