What is the nature of quantum physics? Neil deGrasse Tyson and comedian Chuck Nice get quantum, exploring Schrodinger’s Cat, electrons, Hilbert Space, and the biggest ideas in the universe (in the smallest particles) with theoretical physicist Sean Carroll.

When did the idea of fields originate? Are fields even real or are they just mathematically convenient? We explore electrons, whether they are a field, and whether they exist at all. We also discuss the wave function, Hilbert Space, and what quantum mechanics really is. Do superpositions always exist?

What would happen if Planck’s Constant were macroscopic? Learn about entangling particles and the longest entanglement distances. If the particles are entangled why would the distance matter? Could we make an internet with quantum entanglement? We break down Schrodinger’s cat, its interpretations, and what the thought experiment really means. Do superpositions always exist?

Are there quantum manifestations in the macro-universe? We explore the microwave background, inflation, and how we discovered that atoms are mostly empty. Sean gives his latest takes on dark matter, dark energy, emergence, and free will. Plus, is dark energy really the cosmological constant?

BREVARD COUNTY, FLORIDA – SpaceX is targeting Wednesday, July 24 for a Falcon 9 launch of 23 Starlink satellites to low-Earth orbit from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.

The launch window opens at 12:14 a.m. ET.

A SpaceX Falcon 9 rocket will launch another batch of second-generation Starlink satellites.

According to the Speedtest Global Index, Australia ranks 64th in the world for fixed broadband speeds making it the slowest internet connected developed country with an average download speed of 46.24 Mbps. New Zealand ranks slightly higher at 50th, with an average download speed of 73.87 Mbps.

The Akamai State of the Internet Report says Australia’s internet connection speeds are now slower than 50 other nations, including Thailand, Estonia, Bulgaria and Kenya.

Aston University researchers and their international team have set a new data transmission record of 402 terabits per second using standard optical fiber, potentially stabilizing broadband costs as demand surges.

Researchers at Aston University, collaborating with a team, have achieved a new record by transmitting data at a rate of 402 terabits per second through commercially available optical fiber. This accomplishment surpasses their prior record set in March 2024, where they managed to send data at 301 terabits per second, equivalent to 301,000,000 megabits per second, using a single standard optical fiber.

According to the researchers, “If compared to the internet connection speed recommendations of Netflix, of 3 Mbit/s or higher, for watching an HD movie, this speed is over 100 million times faster.”

AI will enable drone wingmen to make autonomous decisions without centralized command.

According to Airbus, FCAS will be centered around a core Next Generation Weapon System (NGWS). In this “system of systems,” piloted New Generation Fighters will work together with Unmanned Remote Carriers – all connected to other systems in space, in the air, on the ground, at sea and in cyberspace via a data cloud called the “Combat Cloud.”

The FCAS is one more step towards the goal of achieving full collaborative combat by 2040, which can replace military systems like Rafale and Eurofighter.

Airbus says that an incremental roll-out of FCAS capabilities is planned by implementing initial situational awareness across platform capabilities in the mid-2020s.

The proposed innovative design leads to unprecedented power conversion efficiency and improved versatility. A recently developed wirelessly powered 5G relay could accelerate the development of smart factories, report scientists from Tokyo Tech. By adopting a lower operating frequency for wireless power transfer, the proposed relay design solves many of the current limitations, including range and efficiency. In turn, this allows for a more versatile and widespread arrangement of sensors and transceivers in industrial settings.

One of the hallmarks of the Information Age is the transformation of industries towards a greater flow of information. This can be readily seen in high-tech factories and warehouses, where wireless sensors and transceivers are installed in robots, production machinery, and automatic vehicles. In many cases, 5G networks are used to orchestrate operations and communications between these devices.

To avoid relying on cumbersome wired power sources, sensors and transceivers can be energized remotely via wireless power transfer (WPT). However, one problem with conventional WPT designs is that they operate at 24 GHz. At such high frequencies, transmission beams must be extremely narrow to avoid energy losses. Moreover, power can only be transmitted if there is a clear line of sight between the WPT system and the target device. Since 5G relays are often used to extend the range of 5G base stations, WPT needs to reach even further, which is yet another challenge for 24 GHz systems.

Apple is developing technology that would allow any number of willing people in close proximity to start an audio chat, using only an iPhone and a headset like AirPods, with no WiFi or cell service needed.

Instantaneous communication like the Walkie-Talkie feature on the Apple Watch would be possible but with groups of people instead of individuals.

Unlike the Walkie-Talkie feature, this new technology would eliminate the roundtrip to Apple’s cloud servers, a step that makes Walkie-Talkie unreliable at times. Also, unlike Walkie-Talkie, this would allow groups of willing people to talk to each other simultaneously.

The performance of artificial intelligence (AI) tools, including large computational models for natural language processing (NLP) and computer vision algorithms, has been rapidly improving over the past decades. One reason for this is that datasets to train these algorithms have exponentially grown, collecting hundreds of thousands of images and texts often collected from the internet.

Training data for robot control and planning algorithms, on the other hand, remains far less abundant, in part because acquiring it is not as straightforward. Some computer scientists have thus been trying to create larger datasets and platforms that could be used to train computational models for a wide range of robotics applications.

In a recent paper, pre-published on the server arXiv and set to be presented at the Robotics: Science and Systems 2024 conference, researchers at the University of Texas at Austin and NVIDIA Research introduced one of these platforms, called RoboCasa.
