Grappling With Waste…
The underground Onkalo repository in Finland is designed to safely and permanently store hazardous, radioactive waste. Credit: Posiva Topics: Environment, High Energy Physics, Nuclear Power Finland and the former Yugoslavia adopted nuclear energy only four years apart. In 1971 Finland began construction of its first nuclear plant, Loviisa, and the first of two planned reactorsContinue reading “Grappling With Waste…”

Beyond Attogram Imaging…
When X-rays (blue color) illuminate an iron atom (red ball at the center of the molecule), core-level electrons are excited. X-ray excited electrons are then tunneled to the detector tip (gray) via overlapping atomic/molecular orbitals, which provide elemental and chemical information about the iron atom.

Critical, or Magical…
Topics: Civilization, Climate Change, Existentialism, Science Fiction, Star Trek Critical thinking is the intellectually disciplined process of actively and skillfully conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication, as a guide to belief and action. In its exemplary form, it is based on universal intellectualContinue reading “Critical, or Magical…”
Straining Moore…
Topics: Applied Physics, Chemistry, Computer Science, Electrical Engineering, Materials Science, Nanotechnology, Quantum Mechanics, Semiconductor Technology Gordon Moore, the co-founder of Intel who died earlier this year, is famous for forecasting a continuous rise in the density of transistors that we can pack onto semiconductor chips. James McKenzie looks at how “Moore’s law” is still going strong afterContinue reading “Straining Moore…”
