Law of “Infodynamics” Supports Theory That We Are Living in a Simulation

Posted by in categories: computing, Elon Musk, physics

A University of Portsmouth physicist has explored whether a new law of physics could support the much-debated theory that we are simply characters in an advanced virtual world.

The simulated universe hypothesis proposes that what humans experience is actually an artificial reality, much like a computer simulation, in which they themselves are constructs.

The theory is popular among a number of well-known figures including Elon Musk, and within a branch of science known as information physics, which suggests physical reality is fundamentally made up of bits of information.

Topology Makes On-Chip Terahertz Beamforming a Reality

Posted by in category: computing

A new silicon topological beamformer chip can beam terahertz frequency wireless signals in any direction.

Terahertz waves are located between optical waves and microwaves on the electromagnetic spectrum.


The achievement could open a new swath of spectrum for wireless networks.

Hybrid RF-VLC system could reduce power consumption in wireless networks

Posted by in categories: computing, internet

Wireless internet supports the daily activities of countless people worldwide, ranging from their professional communications to internet browsing and the streaming of movies or TV series. This spiking demand for wireless internet access goes hand in hand with greater power consumption, which in turn contributes to carbon emissions worldwide.

Future wireless networks should be able to support the high computational demands of many modern applications and internet services, while limiting power consumption. Some researchers have thus been developing energy efficient techniques supporting between devices and the sharing of media or other information online.

One of these solutions is known as communication (VLC). This is a method to realize efficient wireless communication using visible light to transmit data, relying on (LEDs) or other artificial light sources.

Discrete and Continuous Processes in Computers and Brains

Posted by in categories: computing, neuroscience, physics

Theories of computation and theories of the brain have close historical interrelations, the best-known examples being Turing’s introspective use of the brain’s operation as a model for his idealized computing machine (Turing 1936), McCulloch’s and Pitts’ use of ideal switching elements to model the brain (McCulloch and Pitts 1943), and von Neumann’s comparison of the logic and physics of both brains and computers (von Neumann 1958).

What Are the Benefits of Integrating Nanotechnology into IoT?

Posted by in categories: business, computing, nanotechnology

With inventions like a nanomaterial-based battery for IoT and nanoscale transistors, the future of nanotechnology in this field seems to have potential. For now, any large-scale applications are likely years away. Companies must overcome technical, cost, and implementation hurdles before progressing to mass-market applications.

However, numerous nanoscale-sized discoveries and inventions will likely emerge in the coming years. As the value of nanotechnologies and IoT continue increasing, more investors, business owners, and researchers will explore possible use cases. While their inventions may not hit shelves for years, their development speed will surely accelerate.
