Could classical theory be just as weird as quantum theory?

Quantum mechanics is often described as "weird" and "strange" because it abandons many of the intuitive traits of classical physics. For example, the ideas that the world is objective, is deterministic, and exists independent of measurement are basic features of classical theory, but do not always hold up in quantum theory.

Pen draws flexible circuits using half-meter long carbon nanotube fibers

(—While it may look like researchers from Tsinghua University in Beijing are sketching out an idea for a circuit on a piece of paper, they're actually using a special pen that draws real circuits using carbon-nanotube-based ink.

Rapidly reconfigurable waveform generator on a CMOS chip could be used for high-speed wireless communication

(—An arbitrary waveform generator can, as its name implies, generate waves of almost any shape by controlling the amplitude, frequency, phase, and other wave characteristics. Waveform generators working in the radio frequency...Show More Summary

Red light goes green: Metal-free organic sensitizers portend significant advance in artificial photosynthesis

(—Photosynthesis – the ubiquitous yet remarkable process by which most plants, algae, and cyanobacteria convert light energy into chemical energy – provides the atmospheric oxygen and organic compounds fundamental to the evolution...Show More Summary

Nano switch could store memory using coordinated 'dance' of atoms

( —In one of the tiniest switches ever made, five atoms appear to "dance" around each other in a complex choreographic sequence, with their final arrangement corresponding to one of two stable states. This concerted motion of...Show More Summary

Scientists go to great lengths to extend superlow friction

(—When nanosized pieces of graphite slide against each other, there can be virtually no friction between them. For many years, superlow friction, or "superlubricity," was known to exist only on the nanoscale. Then in 2012, scientists...Show More Summary

No Big Bang? Quantum equation predicts universe has no beginning

( —The universe may have existed forever, according to a new model that applies quantum correction terms to complement Einstein's theory of general relativity. The model may also account for dark matter and dark energy, resolving multiple problems at once.

Kitchen sponge supercapacitor has many porous benefits

By dipping small pieces of an ordinary kitchen sponge into solutions of nanoscale electrode materials, scientists have created a light-weight, low-cost supercapacitor that benefits from the sponge's porous structure. The pores provide...Show More Summary

Nuclear pasta may offer insight into strange world of neutron stars

(—Neutron stars, which form when massive stars collapse under their own enormous gravity, are some of the densest objects in the universe, second only to black holes. Yet while little is known about the interiors of black holes,...Show More Summary

Black holes do not exist where space and time do not exist, says new theory

( —The quintessential feature of a black hole is its "point of no return," or what is more technically called its event horizon. When anything—a star, a particle, or wayward human—crosses this horizon, the black hole's massive gravity pulls it in with such force that it is impossible to escape. Show More Summary

The clime's speech: Data analysis supports prediction that human language is influenced by environmental factors

(—Human speech is not typically thought to adapt to the environment, and a standard assumption in linguistics is that sound systems are in fact immune to ecological effects. Recently, however, scientists at University of Miami...Show More Summary

Popper's experiment realized again—but what does it mean?

(—Like Einstein, the philosopher Karl Popper was a realist who was deeply bothered by some of the odd implications of quantum mechanics. Both Popper and Einstein disliked the idea in Heisenberg's uncertainty principle, for instance,...Show More Summary

First-of-its-kind tube laser created for on-chip optical communications

(—Nanophotonics, which takes advantage of the much faster speed of light compared with electrons, could potentially lead to future optical computers that transmit large amounts of data at very high speeds. Working toward this...Show More Summary

Reversible solid-to-liquid phase transition offers new way to synthesize crystals

( —The simple acts of heating and cooling affect different substances in different ways: some substances may change phase from solid to liquid to gas, while others may irreversibly break down when heat is applied. In a new study,...Show More Summary

Water-soluble silicon leads to dissolvable electronics

(—Researchers working in a materials science lab are literally watching their work disappear before their eyes—but intentionally so. They're developing water-soluble integrated circuits that dissolve in water or biofluids in months, weeks, or even a few days. Show More Summary

DNA does design: 3D plasmonic photonic crystals are the first devices prepared by DNA-guided colloidal crystallization

(—As biotechnology and nanotechnology continue to merge, DNA-programmable methods have emerged as a way to provide unprecedented control over the assembly of nanoparticles into complex structures, including customizable periodic...Show More Summary

How well can information be stored from the beginning to the end of time?

(—Information can never be stored perfectly. Whether on a CD, a hard disk drive, or a piece of papyrus, technological imperfections create noise that limits the preservation of information over time. But even if you had a perfect...Show More Summary

Metasurface solves calculus problems as an analog computer

Scientists have demonstrated that a 2-D man-made material called a metasurface can perform spatial differentiation and integration, the two main types of calculus problems, when illuminated by a laser beam. Essentially, the metasurface...Show More Summary

Metamaterial prism creates a reverse rainbow

(—In a normal rainbow, red is always on "top" while violet is on the "bottom." This is true whether the rainbow is created by a glass prism or by water droplets in the sky, and is due to the way that these materials refractShow More Summary

Super-insulated clothing could eliminate need for indoor heating

(—By wearing clothes that have been dip-coated in a silver nanowire (AgNW) solution that is highly radiation-insulating, a person may stay so warm in the winter that they can greatly reduce or even eliminate their need for heating their home. Show More Summary
