(Phys.org)—Werner Heisenberg originally proposed the uncertainty principle in 1927, but his original proposal was somewhat different than how it is interpreted today. As a recent paper in Physical Review Letters explains, Heisenberg’s original statement was about error and disturbance in a measurement process. Over the years, however, Heisenberg’s original proposal has been restated in terms of the uncertainties intrinsic to quantum states. This aspect of the uncertainty principle has been studied extensively with well-developed theories and verified experimentally.

On the other hand, Heisenberg’s original proposal regarding error in the measurement process is not as well understood. In the new paper, a team of researchers led by Professor Jiangfeng Du at the University of Science and Technology of China has reported an experimental test of the measurement aspect of Heisenberg’s uncertainty principle using nuclear-spin qubits.

In his original proposal, Heisenberg predicted a tradeoff between error and disturbance. He suggested that when a gamma-ray microscope measures the position of an electron, the measurement inevitably disturbs the electron’s momentum. The smaller the measurement error, the larger the disturbance, and vice versa. This idea was described qualitatively but a complete quantitative description is still lacking today.

Patents filed on many pre-existing 3D printing processes are about to expire. As this occurs, it will bring on a new era in 3D printing. Machinery and material costs will plummet, and the quality of prints will increase.

An important shift is occurring in the 3D printing world: patents are expiring. Patents filed on pre-existing industrial printing processes, especially those filed at the turn of the century, have already expired or are set to expire in the coming years.

Take, for example, the case of Fused Deposition Modeling (FDM). The patent on FDM expired in 2009. As a result, prices for FDM printers dropped from over $10,000 to less than $1,000, which caused consumer-friendly 3D printer manufacturers– like MakerBot and Ultimaker– to pop up.

A team of theoretical physicists used Loop Quantum Gravity, string theory’s biggest contender, and showed that the calculations are consistent with the idea that black holes have no insides, but that objects are stuck on their surface.

There’s a lot in our universe we don’t completely understand, such as dark matter and dark energy. Indeed, in the bizarre world of quantum physics, ideas are constantly shifting and changing regarding the true nature of the (somewhat mysterious) forces that govern our universe.

This is what’s happening now in the debate over what black holes really are.

Mathematically it makes sense.

Practically speaking, it’s pretty much irrelevant.

Not a big fan of laundry day? Well what if you could wash your clothes just by stepping into the sunshine? Thanks to researchers at RMIT University in Melbourne, a self-cleaning textile could make that possible in the very near future. With the help of special nanostructures grown directly into the fabric, these new textiles could degrade organic matter like dirt, dust, and sweat when exposed to a concentrated light source.

To achieve this effect, the nanostructures used by the RMIT University team are made copper and silver. These metals are great at absorbing visible light, and when they’re exposed to light from the sun or even a light bulb, the nanostructures react with increased energy that creates “hot electrons”.
