Improving measurements by reducing quantum noise
If you want to measure something very precisely, such as slight variations of a length, then you are very likely to use light waves. However, many effects, such as variations of gravity, or surface forces, ...
3D-printer with nano-precision
Printing three dimensional objects with incredibly fine details is now possible using "two-photon lithography". With this technology, tiny structures on a nanometer scale can be fabricated. Researchers at ...
Is it real? Physicists propose method to determine if the universe is a simulation
Newly discovered celestial object defies categories
An object discovered by astrophysicists at the University of Toronto (U of T) nearly 500 light years away from the Sun may challenge traditional understandings about how planets and stars form.
Ultra-fast, the bionic arm can catch objects on the fly (w/ Video)
A robot developed by EPFL researchers is capable of reacting on the spot and grasping objects with complex shapes and trajectories in less than five-hundredths of a second.
On the origins of the Schrodinger equation
Does the quantum wave function represent reality?
Entanglement between particle and wave-like states of light resembles Schrodinger's cat experiment (Update)
Hubble finds telltale fireball after gamma ray burst
(Phys.org) —NASA's Hubble Space Telescope has provided the strongest evidence yet that short-duration gamma-ray bursts are triggered by the merger of two small, super-dense stellar objects, such as a pair ...
Testing Einstein's E=mc2 in outer space
(Phys.org)—University of Arizona physicist Andrei Lebed has stirred the physics community with an intriguing idea yet to be tested experimentally: The world's most iconic equation, Albert Einstein's E=mc2, may be cor ...
The galaxy's ancient brown dwarf population revealed
(Phys.org) —A team of astronomers led by Dr David Pinfield at the University of Hertfordshire have discovered two of the oldest brown dwarfs in the Galaxy. These ancient objects are moving at speeds of ...
