Interesting Engineering on MSN: New theory shows time exists in quantum superpositions, ticks fast and slow
New theory shows time exists in quantum superpositions, ticks fast and slow
Adelaide University researchers have successfully tested a new type of portable atomic clock at sea for the first time, using technology that could help power the next generation of navigation, ...
Objects of atomic types are the only C++ objects that are free from data races; that is, if one thread writes to an atomic object while another thread reads from it, the behavior is well-defined. In …
I had a 25-hr debugging marathon in < 2 days and then wrote this answer here. See also the bottom of this question for more info. and documentation on 8-bit variables having naturally atomic …
22 Atomic vs. Non-Atomic Operations "An operation acting on shared memory is atomic if it completes in a single step relative to other threads. When an atomic store is performed on a shared …
There are two atomic CAS operations in C++11: atomic_compare_exchange_weak and atomic_compare_exchange_strong. According to cppreference: The weak forms of the functions are …
In addition (and more importantly), note that std::atomic must support all operations for all possible data types, so even if you declare a ten million byte struct, you can use compare_exchange on …
When can 64-bit writes be guaranteed to be atomic, when programming in C on an Intel x86-based platform (in particular, an Intel-based Mac running MacOSX 10.4 using the Intel compiler)? For …
11 The difference is that a normal load/store is not guaranteed to be tear-free, whereas a relaxed atomic read/write is. Also, the atomic guarantees that the compiler doesn't rearrange or …
So, this means that Richard Barry is saying that 4-byte reads and writes are atomic on these 32-bit microcontrollers. This means that he, at least, is 100% sure 4-byte reads and writes are atomic on …
There are several questions on SO dealing with atomic, and other that deal with std::condition_variable. But my question if my use below is correct? Three threads, one ctrl thread that …
Which types on a 64-bit computer are naturally atomic in gnu C and gnu ...
c++ - What is the difference between load/store relaxed atomic and ...
(bymuratdeniz/iStock/Getty Images Plus) Although there are many variables in life, there's one metric by which our existence is strictly measured: time. We think of it as rigid, smooth, and ...
Time already behaves strangely in modern physics. It can stretch, slow, and split depending on speed and gravity.
Phys.org on MSN: Bringing quantum time into the lab—a single clock can run young and old at once
Few concepts in physics are as familiar, yet as enigmatic, as time. In Einstein's theory of relativity, time is not absolute: its passage depends on motion and gravity. But when combined with quantum ...

Nature: Elusive ‘nuclear clocks’ tick closer to reality — after decades in the making
Physicists are getting closer to creating a long-sought ‘nuclear clock’. This device would keep time by measuring energy transitions in the nuclei of atoms and could become the most precise clock on ...
Elusive ‘nuclear clocks’ tick closer to reality — after decades in the making
Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions. To build a clock, you need something that ticks in a perfectly repeatable way.
MSN: Explainer: What is an atomic clock and why it is crucial for navigation satellites
Ten years after it was placed in orbit as part of the four-spacecraft Indian Regional Navigation Satellite System, the IRNSS-1F’s onboard imported atomic clock, a critical component for providing ...
