Research Problems

close up of water meeting lakeshoreAs the Spring semester rolls around, in this short space between the winter holiday extravaganza and the start of my second semester in Missouri’s library and information science program, I though I’d share some thoughts on a few recent pieces on research. Often positioned as a final boss in education and the thing that keeps people in the academy once basic skill and efforts to cultivate them are exhausted, research can be vexing when done well. When done poorly though whether through negligence or malice it can be catastrophic though interesting.

The first published at Ars Technica concerns a case of problematic interpretation. The setup seems very innovative, the results seem interesting, and then the investigator offers his interpretation involving an outmoded Lamarkian view of evolutionary biology. He devised an apparatus that allowed E. coli to be cultured over a gradient of differing concentrations of nutrients and antibiotics while being able to travel between these cells and observed rapid acquisition of resistance to ciprofloxacin, on the order of ten hours. And then he interprets his results through a pre-Darwinian lens. Presentation abstract available here.

Google may or may not be using Quantum Computer

cat  schrodinger captionFrom the files of the potentially scary while potentially exciting comes news of Google’s venture into what may or may not be quantum computing using technology from D-Wave company who may or may not be marketing the technology that they claim to be.

There’s a lot of coverage out there already, but I just find it interesting where a lot of the commentary is putting out comparisons of this implementation of maybe or maybe not quantum computing to neural networks.  If this connection is realized further, it would support some hunches that I have had for some time.  On the other hand it it creates a computer that is too brain like, we probably will have a good idea as to how an actual implementation of a Skynet like system may or may not differ from its portrayal in fiction.  Hopefully it will be more concerned with why the Google team used such elementary school-type branding on its predecessors than having the world all to itself.

Considering especially the application of this new technology towards image recognition, a task at which people tend to perform very well, the nature of this technology as possibly more of a cousin to cognition than earlier computing technologies sounds rather possible.  Considering also on the other hand the difficulties associated with building quantum computers in academic environments and the consideration offered in other commentaries on D-Wave that its products are likely frauds, jokes, or some form of joke there is the possibility that the Google team is working on its most elaborate April fools day project yet.

Space

153212main_canister-430 Friday NASA released its crew assignment for the last scheduled space shuttle mission.  The twelfth Chief of the Astronaut Office Steven Lindsey will be leading the crew of six astronauts on the Space Shuttle Discovery piloted by Eric Boe for mission STS-133.  Two of the crew members assigned to serve as mission specialists for this mission, Nicole Stott and Michael Barratt, are currently on the International Space Station on it first long term six person crew.  Filling out the crew as mission specialists are Benjamin Drew and Timothy Kopra.
Beyond this mission there is a lot of uncertainty as to what the future holds for manned space flight. A timetable for replacing the space shuttle with either a NASA craft or commercial alternative is still indeterminate, and there is talk of deorbiting the International Space Station as soon as 2016.  It is a shame that the station would be discarded after such a short lifespan, the current crew is its first six person complement.  Still there is talk that Russia may keep the modules it contributed in space for use in a future Russian space station.

Then there is the possibility that the Space Shuttles with be kept in service for a few more years.  Space flight is an endeavor typically characterized by small margins for error, extensive planning, and the unknown.  At this point in history it seems that the unknown, of the economic and political variety, is the dominant factor lingering over manned space flight in the United States.

With all of the common warning signage people come across finding a new warning symbol in an unexpected place can be a bit of a surprise. From the fairly benign admonition that coffee is served hot to the more pressing matter of bringing to your attention via a blinking light that your breaks might not be in suitable condition to reliably stop your car. Then there’s the generic caution tape. Well below is the most effective sign I believe I have encountered.
