It is often assumed that a structure’s surface can be appropriately represented as a two-dimensional area, completely flat and devoid of any depth. However, in reality, two-dimensional surfaces do not exist in nature, if zoomed in sufficiently even the most seemingly flat surface has 3-dimensional structure. This can pose a problem when physics that have been formulated with two-dimensions are re-examined using a more realistic 3D model.
Just such a situation arose when astronomer Martin Asplund forewent the usual 2D model of the Sun’s surface, and instead used a supercomputer to model it as 3-dimensional surface. Asplund was hoping to formulate a more accurate model for analyzing spectral and seismological data to better understand the Sun’s interior.
Since the interior cannot be directly observed, sound and light emissions emanating from the Sun’s surface are a window into the...
The EM drive – a radio frequency (RF) resonant cavity thruster – appears to produce an ‘impossible’ thrust. Impossible – in that it apparently violates Newtons third law of motion: “For every action, there is an equal and opposite reaction.” Now in a recent paper by a group of Portuguese physicists, led by Prof. Jose Croca from the Center for Philosophy of Sciences at the University of Lisbon, present a possible explanation for this observed ‘impossible’ thrust.
The EM drive was first proposed in 2001 by British inventor Roger Sawyer and has subsequently been tested by numerous groups around the world alongside possible explanations for its propulsion. However, still a hot topic of debate, a consensus on the level of thrust and an explanation for the thrust has not been found.
Croca and his team hope to change this through their explanation...
The neurocomputational paradigm is the predominant model of explaining cognitive functioning of the brain – the generation of subjective qualia comprising a state of awareness, phenomenological experiences, as well as learning and memory. As indicated by the name, the neurocomputational model is based on the theory that the brain is analogous to a computer, and therefore mental activity arises from computational operations of neurons, specifically the synaptic connections among them.
This standard model of cognitive biology has faced significant challenges in constructing a coherent and viable explanation by which consciousness, particularly agents with free will, would arise from computational behavior. Leading some, one of the most notable of which is physicist Dr. Roger Penrose, to posit that some “intrinsic” behavior of neuronal activity is operating beyond a...
Metamaterials are a class of super-materials with remarkable characteristics. Metamaterials have been engineered to bend and shape light, providing an effective invisibility cloak.
The EmDrive, originally developed by Roger Shawyer at SPR Ltd., is a propellant-free microwave thruster that produces acceleration via an electromagnetic cavity without need for traditional fuel sources. After several successful experimental demonstrations of the EmDrive’s ability to produce thrust by NASA’s Eagleworks laboratory, several researchers are using the quantum mechanical model of Pilot Wave theory to describe how the engine interacts with the quantum vacuum to produce thrust.

What would you call two people wrapped up in a phone call? Phonon entanglement. This facetious example is actually very analogous to what has been accomplished in a quantum experiment involving two macroscopic (observable to the naked eye) sized diamonds. In this experiment, molecular assemblies seemed to be strongly interrelated between the two diamonds despite being separated by a sizable space. This instantaneous interaction at a distance, in which the quantum state of two particles – or in this case 1016 atoms – appear to be linked together is referred to as entanglement.
Normally this requires extremely cold temperatures (a few degrees above absolute zero), or special containment systems to keep the particles from interacting with the environment. But diamonds have several characteristics that obviate the need for these extreme conditions. Because of the rigid...

In communicating the progress of scientific theories and tests, experimental results are often presented to the public as concrete and indisputable, therefore proving this-or-that idea. This leads to the common misconception that scientific models can in fact become proven, instead of the more nuanced reality that they are only the most precise (sometimes extremely precise) and accurate models approximating what we can discern, and the very notion of evidence always suggest a degree of interpretation.
The results of quantum entanglement experiments are a case-in-point. The results of data from particle accelerators to optical Bell tests (experiments that test entanglement) are statistical, such that conclusions are drawn based on the probability of a series of measurements being random or “true signals”. This goes for detection of Higgs, W, and Z bosons as well as whether...
