The program will join Spring Arbor’s bachelor of science and electrical engineering program within the university’s School of Engineering, which opened last fall, according to a release from the university.

Students will have small class sizes and a strong emphasis on hands-on learning experiences, as well as flexibility to target specific areas of interest within the mechanical engineering field, the release said.

“Mechanical engineering continues to be one of the areas of study with the largest interest from prospective students,” said Jon Bahr, vice president of enrollment and marketing. “Adding this program to our diverse list of degree offerings is crucial in preparing students to be ‘critical participants in the contemporary world.’”

The program, which was built around NASA’s Engineering Design Process, will prepare

Quantum entanglement is the basic phenomenon underlying the functioning of a variety of quantum systems, including quantum communication, quantum sensing and quantum computing tools. This phenomenon results from an interaction (i.e., entanglement) between particles. Attaining entanglement between distant and very different objects, however, has so far proved highly challenging.


Researchers at the University of Copenhagen have recently generated entanglement between a mechanical oscillator and a collective atomic spin oscillator. Their work, outlined in a paper published in Nature Physics, introduces a strategy for generating entanglement between these two distinct systems.

“About a decade ago, we proposed a way to generate entanglement between a mechanical oscillator and a spin oscillator via photons, using the principle that was later called ‘quantum mechanics free subspaces’ or ‘trajectories without quantum uncertainties,'” said Eugene S. Polzik, who led the group that

Theoretical physicists Kamran Ullah and Hameed Ullah have shown that a position-dependent mass optomechanical system involving a cavity between two mirrors, one attached to a resonator, can enhance induced transparency and reduce the speed of light.


We are all taught at high school that the speed of light through a vacuum is about 300000km/s, which means that a beam from Earth takes about 2.5 seconds to reach the Moon. It naturally moves more slowly through transparent objects, however, and scientists have found ways to slow it dramatically. Optomechanics, or the interaction of electromagnetic radiation with mechanical systems, is a relatively new and effective way of approaching this. Theoretical physicists Kamran Ullah from Quaid-i-Azam University, Islamabad, Pakistan and Hameed Ullah from the Institute of Physics, Porto Alegre, Brazil have now demonstrated how
