Physics and Numbers
A team of scientists led by researchers from Princeton University has discovered a new way that electrons behave in materials. The discovery could lead to new kinds of electronic devices.
In Jim Arnold's blog, we have been having an occasionally enlightening, occasionally exasperating discussion about whether gravitational waves (GWs) exist.
The evidence strongly supports the interpretation of the mathematics of general relativity that says gravitational waves do indeed exist and are, in principle if not yet in practice, observable.
That leads to a question that hasn't come up in Jim's blog but I'd like to raise here: What is the spectrum of gravitational radiation?
Engineering researchers have narrowed the search for the source of X-rays emitted by lightning, a feat that could one day help predict where lightning will strike.
Cymbals don’t clash of their own accord – in our world, anyway. But the quantum world is bizarrely different. Two metal plates, placed almost infinitesimally close together, spontaneously attract each other.
A newly developed nano-sized electronic device is an important step toward helping astronomers see invisible light dating from the creation of the universe.
Scientists at the University of Cambridge have for the first time identified a key component to unravelling the mystery of room temperature superconductivity, according to a paper published in today's edition of the scientific journal Nature.
Another blogger here, who is generally so far off the mark that I don't want to point to his earlier discussion, had some odd things to say about the "Pioneer anomaly," the unexplained deviation of the two Pioneer spacecraft from their predicted trajectory as they pass through the outer reaches of the solar system.
A much more cogent discussion has just appeared.
Baseball diamonds are a left-hander's best friend.
Researchers at North Carolina State University have found that quantum dot nanoparticles can penetrate the skin if there is an abrasion
The National Institute of Standards and Technology (NIST) has released a five-chapter preview of the much-anticipated online Digital Library of Mathematical Functions (DLMF).
The odd behavior of a molecule in an experimental silicon computer chip has led to a discovery that opens the door to quantum computing in semiconductors.
Some school physics books say that energy is the ability to do work. But isn't work the amount of energy transferred?
Researchers in Spain have proven that metamaterials, materials defined by their unusual man-made cellular structure, can be designed to produce an acoustic cloak - a cloak that can make objects impervious to sound waves, literally diverting sound waves around an object.
The physical ambiguity of mathematics in gravitation theory has led to an overextension of the mathematics and resulted in theoretical misdirection.
Using a convenient and flexible method for creating twin light beams, researchers at National Institute of Standards and Technology (NIST) have produced “quantum images,” pairs of information-rich visual patterns whose features are “entangled,” or inextricably linked by the laws of quantum physics.
