In this sense, the cemi theory incorporates Chalmers’ (Chalmers 1995) ‘double-aspect’ principle that information has both a physical, and a phenomenal or experiential aspect. At the particulate level, a molecule of the neurotransmitter glutamate encodes bond energies, angles, etc. but nothing extrinsic to itself. Awareness makes no sense for this kind matter-encoded information: what can glutamate be aware of except itself? Conversely, at the wave level, information encoded in physical fields is physically unified and can encode extrinsic information, as utilized in TV and radio signals. This EM field-based information will, according to the double-aspect principle, be a suitable substrate for experience. As proposed in my earlier paper (McFadden 2002a) ‘awareness will be a property of any system in which information is integrated into an information field that is complex enough to encode representations of real objects in the outside world (such as a face)’. Nevertheless, awareness is meaningless unless it can communicate so only fields that have access to a motor system, such as the cemi field, are candidates for any scientific notion of consciousness.
I previously proposed (McFadden 2013b), that complex information acquires its meaning, in the sense of binding of all of the varied aspects of a mental object, in the brain’s EM field. Here, I extend this idea to propose that meaning is an algorithm experienced, in its entirety from problem to its solution, as a single percept in the global workspace of brain’s EM field. This is where distributed information encoded in millions of physically separated neurons comes together. It is where Shakespeare’s words are turned into his poetry. It is also, where problems and solutions, such as how to untangle a rope from the wheels of a bicycle, are grasped in their entirety.
There are of course many unanswered questions, such as degree and extent of synchrony required to encode conscious thoughts, the influence of drugs or anaesthetics on the cemi field or whether cemi fields are causally active in animal brains. Yet the cemi theory provides a new paradigm in which consciousness is rooted in an entirely physical, measurable and artificially malleable physical structure and is amenable to experimental testing. The cemi field theory thereby delivers a kind of dualism, but it is a scientific dualism built on the distinction between matter and energy, rather than matter and spirit. Consciousness is what algorithms that exist simultaneously in the space of the brain’s EM field, feel like.
Read about the importance of International Observe the Moon Night and how you can celebrate it on September 14, 2024!
Beginning in 2010, NASA began International Observe the Moon Night based on two events occurring simultaneously in 2009 during the International Year of Astronomy celebration: “We’re at the Moon!”, which was sponsored by the Lunar Reconnaissance Orbiter (LRO) and the Lunar Crater Observation and Sensing Satellite (LCROSS) teams, and “National Observe the Moon Night”, which was hosted in the United States.
This year’s International Observe the Moon Night is occurring on September 14 with the goal of sharing the incredible science and wonder of the Moon, including its observational and scientific history, why it’s so important to study, and how we’re studying it. For example, evidence has suggested that ancient humans as far back as 20,000 years ago used the Moon as a timekeeping device due to the changing phases of the Moon over the course of a month. Additionally, when observing the Moon with either the naked eye or a telescope, the Moon’s surface exhibits both bright and dark colors, which are the Moon’s lava plains and highlands, respectively.
Regarding its scientific history, the Moon has been studied by astronomers around the world for hundreds of years, with one of the first astronomers to observe the Moon through a telescope and document their findings being Galileo Galilei, finding the Moon’s surface was imperfect and not smooth as had been previously hypothesized. Regarding robotic exploration, the Moon has been explored in-depth beginning with the Soviet Union intentionally crashing the Luna 2 space probe onto the lunar surface on September 14, 1959. This Space Race between the United States and Soviet Union culminated with the United States landing the first man on the Moon in 1969 with Apollo 11.

Do cities get more rainfall than rural areas?
How does an urban environment influence its rainfall? This is what a recent study published in the Proceedings of the National Academy of Sciences hopes to address as a team of researchers investigated what is known as the urban precipitation anomaly, which is when urban environments potentially cause increases in rainfall compared to rural environments due to increased surface temperatures. This study holds the potential to help researchers, climate scientists, and the public better understand the impact that urban environments have on the climate, specifically as climate change continues to ravage the planet.
For the study, the researchers analyzed urban precipitation anomalies across 1.056 cities around the world with the goal of ascertaining the scope of these anomalies based on location and present climates and developing more accurate climatology datasets and greater resilience among cities. In the end, the researchers found that 60 percent of cities around the world have increased levels of urban precipitation anomalies, with the most extreme anomalies occurring in Africa where the surface temperatures are already high, with one factor being tall buildings result in wind being funneled into city centers.
“The buildings further enhance this convergence by slowing the winds, resulting in a stronger upward motion of air. This upward motion promotes the condensation of water vapor and cloud formation, which are critical conditions for producing rainfall and precipitation,” said Dr. Zong-Liang Yang, who is a professor in the Department of Earth and Planetary Sciences at the University of Texas at Austin and a co-author on the study.
By tapping into a decades-old mathematical principle, researchers are hoping that Kolmogorov-Arnold networks will facilitate scientific discovery.
September’s full Harvest Moon will drift into Earth’s shadow for a partial eclipse on Sept. 17. It is also the second of four consecutive supermoons this year, making our natural satellite look bigger and brighter than usual.
An up-and-coming startup in the world of AI chips might be giving Nvidia a run for its money.
Life insurers and those offering income protection and permanent disability insurance will be banned from using genetic testing to refuse cover, or hike up charges, for a range of insurance products.
The federal government announced on Tuesday it would ban the practice that saw consumers discriminated against if they disclosed the results of genetic tests that predict their likelihood of an inherited disease.
It comes after consultation to address genetic discrimination in life insurance earlier this year. More than 1,000 submissions were received with 97 per cent supporting a total ban.
