2:15 PM | Algorithmic view of historicity and separation of scales in biology

A Science publications is one of the best ways to launch your career, especially if it is based on your undergraduate work, part of which you carried out with makeshift equipment in your dorm! That is the story of Thomas M.S. Chang, who in 1956 started experiments (partially carried out in his residence room in […]

12:08 PM | Reading Diary: The Golden Ticket: P, NP, and the Search for the Impossible by Lance Fortnow

Someone shoot me if I ever use the term NP-complete in a sentence. Or at least if I ever use the term in a conversation with “civilians.” Such is the dilemma of reading and reviewing a wonderful book like Lance Fortnow’s The Golden Ticket: P, NP, and the Search for the Impossible. I’ll be tempted…

1:30 AM | Four color problem, odd Goldbach conjecture, and the curse of computing

For over twenty-three hundred years, at least since the publication of Euclid’s Elements, the conjecture and proof of new theorems has been the sine qua non of mathematics. The method of proof is at “the heart of mathematics, the royal road to creating analytical tools and catalyzing growth” (Rav, 1999; pg 6). Proofs are not […]

3:12 PM | Researchers Cook Solar Cells in Old Microwave Oven

University of Utah metallurgists created a “recipe” to produce solar cell material in a microwave oven. Using this kitchen appliance, a nanocrystal semiconductor suitable for photovoltaic applications can be manufactured rapidly from cheap abundant and less toxic metals than other semiconductors. Scientists hope that this new method will be used for more efficient photovoltaic solar cells and LED lights, biological sensors and systems to convert waste heat to electricity. Read more »
