The universe seems neither benign nor hostile, merely indifferent to the concerns of such creatures as we. -Sagan.
I’ve been meaning to post something about The Big Bang Theory for a while now but it’s taken me ‘till now to really understand what it is about the show that makes me uncomfortable. I’m not exactly a believer in the whole “only write about the things you like, don’t trash the things you don’t” trend which seems to be plaguing comments sections in negative articles lately, but I wanted to be able to really examine why I don’t like TBBT rather than just slagging it off. My main questions being - Why don’t I like this anymore? Why do I feel uncomfortable watching it? And why do I get so annoyed when I see people sing its praises online? The thing which really sparked this post was seeing a raft of comments on Facebook, below the last round of voting in Television Without Pity’s Tubey Awards, claiming The Big Bang Theory to be “the best comedy on TV”. This made me angry so instead of posting an impulsive comment calling out their bad taste which I’d probably regret later, I decided to really analyse why seeing comments like that made me so mad when previously, although I didn’t really love the show, I’d never considered myself as disliking The Big Bang Theory.
Hell, I even have season one on dvd, it’s sitting right between Battlestar Galactica and Bored To Death in my alphabetised collection.
And here, I think, is where my problem with The Big Bang Theory lies…
Material Rebuilds Itself Through Chemical Communication |
Self-moving gels can give synthetic materials the ability to “act alive” and mimic primitive biological communication, University of Pittsburgh researchers have found.
In a paper published in the Jan. 8 print edition of the Proceedings of the National Academy of Sciences, the Pitt research team demonstrates that a synthetic system can reconfigure itself through a combination of chemical communication and interaction with light.
Anna Balazs, principal investigator of the study and Distinguished Professor of Chemical and Petroleum Engineering in Pitt’s Swanson School of Engineering, has long studied the properties of the Belousov-Zhabotinsky (BZ) gel, a material first fabricated in the late 1990s and shown to pulsate in the absence of any external stimuli.
In a previous study, the Pitt team noticed that long pieces of gel attached to a surface by one end “bent” toward one another, almost as if they were trying to communicate by sending signals. This hint that “chatter” might be taking place led the team to detach the fixed ends of the gels and allow them to move freely.
Balazs and her team developed a 3-D gel model to test the effects of the chemical signaling and light on the material. They found that when the gel pieces were moved far apart, they would automatically come back together, exhibiting autochemotaxis — the ability to both emit and sense a chemical, and move in response to that signal. continue reading
