Physical systems evolve at a particular speed, which depends on various factors including the system's so-called topological structure (i.e., spatial properties that are preserved over time despite any physical changes that ...
Recent technological advances have enabled the development of increasingly advanced telescope and astrophysical instruments. This includes the IceCube telescope, which was originally built to detect and examine high-energy ...
Quantum mechanics has fundamental speed limits—upper bounds on the rate at which quantum systems can evolve. However, two groups working independently have published papers showing for the first time that quantum speed ...
(Phys.org)—Quantum engines are known to operate differently than—and in some cases, outperform—their classical counterparts. However, previous research on the performance of quantum engines may be overestimating their ...
(Phys.org)—Physicists have theoretically shown that, when multiple nanoscale batteries are coupled together, they can be charged faster than if each battery was charged individually. The improvement arises from collective ...
(Phys.org)—In order to determine how fast quantum technologies can ultimately operate, physicists have established the concept of "quantum speed limits." Quantum speed limits impose limitations on how fast a quantum system ...
(Phys.org) —Last week saw the physics community buzzing as a physicist suggested that the speed of light might be slower than thought—James Franson of the University of Maryland posted an article in a peer-review journal ...
Even though quantum computers are a young technology and aren't yet ready for routine practical use, researchers have already been investigating the theoretical constraints that will bound quantum technologies. One of the ...

(PhysOrg.com) -- Microsoft is planning to tap into the intimate knowledge taxi drivers have of their cities to improve their online mapping systems and help drivers navigate to their destinations faster.
With the speed of computers so regularly seeing dramatic increases in their processing speed, it seems that it shouldn't be too long before the machines become infinitely fast -- except they can't.

A road speed limit is the maximum speed allowed by law for road vehicles. Speed limits are commonly set and enforced by the legislative bodies of nations or provincial governments, such as countries within the world.
The first maximum speed limit was the 10 miles per hour (16 km/h) limit introduced in the United Kingdom in 1861.
The Isle of Man is the only place in the world that does not have a general speed limit. In Germany, over 50% of the autobahn system remains free from speed limits.
Currently, the highest posted speed limit in the world is 140 kilometres per hour (87 mph) on Polish motorways , although a variable speed limit up to 160 kilometres per hour (99 mph) was permitted experimentally on a stretch of Austrian motorway in June 2006.
