A collection of recent research and findings in the fields of physics, astrophysics, and astronomy.
Vibrations of a tiny cantilever could help reveal why quantum rules fail on large scales.
Using what is known as an attosecond experiment, physicists have managed to completely measure and describe the quantum-mechanical wave function of an ionized electron.

Students learn about the scientific and mathematical concepts around electromagnetic light properties that enable the engineering of sunglasses for eye protection. They compare and contrast tinted and polarized lenses as well as learn about light intensity and how different mediums reduce the intensities of various electromagnetic radiation wavelengths. Through a PowerPoint® presentation, students learn about light polarization, transmission, reflection, intensity, attenuation, and Malus’ law. A demo using two slinky springs helps to illustrate wave disturbances and different-direction polarizations. As a mini-activity, students manipulate slide-mounted polarizing filters to alter light intensity and see how polarization by transmission works. Students use the Malus’ law equation to calculate the transmitted light intensity and learn about Brewster’s angle. Two math problem student handouts are provided. Students also brainstorm ideas on how sunglasses could be designed and improved, which prepares them for the associated hands-on design/build activity.

Credit: Shrapnel et al. Published in the New Journal of Physics Quantum theory is based heavily on probabilities, since measuring a quantum system doesn't produce the same outcome every time, but instead yields one of many outcomes that each occur with a certain probability. Now in a new paper, physicists have presented a new quantum probability rule for assigning probabilities to measurement outcomes, or events, that essentially combines two of the most important quantum probability rules (the
Quantum theorist Christopher Fuchs explains how to solve the paradoxes of quantum mechanics. His price: physics gets personal.

The development of quantum mechanics in the first decades of the twentieth century came as a shock to many physicists. Today, despite the great successes of quantum mechanics, arguments continue about its meaning, and its future.

Sculptor Katie Grinnan first unveiled the sculpture “Mirage” in 2011, offering an exploration of movement and space. Constructed from friendly plastic, sand, and enamel, the piece first debuted as part of an exhibition at Brennan & Griffin. The piece is actually a cast of Grinnan’s own body, set in various poses during a yoga routine. The work also calls back to Hindu art, in which gods display several limbs and omnipresence.
