Mind-body philosophy | solving the hard problem of consciousness.

Recent advances in science and technology have allowed us to reveal — and in some cases even alter — the innermost workings of the human body. With electron microscopes, we can see our DNA, the source code of life itself. With nanobots, we can send cameras throughout our bodies and deliver drugs directly into the areas where they are most needed. We are even using artificially intelligent robots to perform surgeries on ourselves with unprecedented precision and accuracy.

Materialism says that the cosmos, and all that is contains, is an objective physical reality. As a result, philosophers who subscribe to this school of thought assert that consciousness, and all that it entails, arises from material interactions. As such, the material world (our flesh, neurons, synapse, etc.) is what creates consciousness.

Idealism says that the universe is entirely subjective and that reality is something that is mentally constructed. In other words, consciousness is something that is immaterial and cannot be observed or measured empirically. Since consciousness is what creates the material world, according to this school of thought, it is unclear if we can ever truly know anything that is mind-independent and beyond our subjective experience.

Dualism essentially holds that mental phenomena are, in some respects, non-physical in nature. In this respect, the mind and the body exist, but they are distinct and separable.

Although most modern philosophers subscribe to the materialist view, determining, and ultimately understanding, the nature of human consciousness using an empirical methodology is a remarkably difficult task. The primary issue with accomplishing the aforementioned is that empirical science requires things to be measured objectively. And when it comes to consciousness, everything is subjective.

Ingenuity, the helicopter currently zipping its way around Mars, has been a hotly watched topic here at UT. After completing its 21st mission and being on the planet for a little over a year, Ingenuity’s handlers have officially extended its mission in the hopes that it will continue its stellar, groundbreaking performances.

Perseverance, Ingenuity’s rover companion, is transitioning into its second scientific campaign, where it plans to travel 130 meters up from the Jezero crater floor to a dried-up river delta. Here it will focus on one of its primary missions – searching for evidence of ancient life on Mars. And Ingenuity will help lead the way.

Even Ingenuity’s path to the river delta, which isn’t limited to staying on the ground, won’t be easy. It will likely take three separate flights to get to a new staging area in the delta, including one that goes around a hill that rises off the crater floor. During this time, it will help scout a pathway for Perseverance to take, including providing information to decide which of two river channels the rover should take to reach the delta itself.

Is alien contact likely and if it happens what would be the consequences? Takeaways from the German SETI meeting.

Whether (some) UAP sightings are evidence of an alien presence or not, and whether aliens exist or not, the broad consensus of the IFEX workshop was that we should be prepared for alien contact. Too many catastrophes have occurred in humanity’s past because we were unprepared.

In January 1992, two cosmic objects forever changed our galaxy.

For the first time, we had concrete evidence of extrasolar planets, or exoplanets, orbiting an alien star: two rocky worlds, whirling around a star 2,300 light-years away.

Now, just over 30 years later, that number has exploded. This week, March 21 marked the hugely significant milestone of over 5,000 exoplanets confirmed. To be precise, 5,005 exoplanets are now documented in the NASA exoplanet archive, every one with its own unique characteristics.

For self-driving cars and other applications developed using AI, you need what’s known as “deep learning”, the core concepts of which emerged in the ’50s. This requires training models based on similar patterns as seen in the human brain. This, in turn, requires a large amount of compute power, as afforded by TPUs (tensor processing units) or GPUs (graphics processing units) running for lengthy periods. However, cost of this compute power is out of reach of most AI developers, who largely rent it from cloud computing platforms such as AWS or Azure. What is to be done?

Well, one approach is that taken by U.K. startup Gensyn. It’s taken the idea of the distributed computing power of older projects such as SETI@home and the COVID-19 focussed Folding@home and applied it in the direction of this desire for deep learning amongst AI developers. The result is a way to get high-performance compute power from a distributed network of computers.

Gensyn has now raised a $6.5 million seed led by Eden Block, a web3 VC. Also participating in the round is Galaxy Digital, Maven 11, Coinfund, Hypersphere, Zee Prime and founders from some blockchain protocols. This adds to a previously unannounced pre-seed investment of $1.1 millionin 2021 — led by 7percent Ventures and Counterview Capital, with participation from Entrepreneur First and id4 Ventures.

In the last decades of his life, Albert Einstein hoped to unite his description of gravity with existing models of electromagnetism under a single master theory.

It’s a quest that continues to vex theoretical physicists to this day. Two of our best models of reality – Einstein’s general theory of relativity and the laws of quantum mechanics – are as immiscible as oil and water.

Whatever a combination of the two looks like, it will almost certainly reveal foundations to the Universe quite unlike anything we can visualize.

A harsh sun shines down through a cloudless sky, across a vast and unforgiving landscape. It’s covered in gray rock, giant ice sculptures and expansive fields of spiky, yellow and orange bushes. In the distance, intimidating mountain peaks dominate the desolate scene, many miles from the nearest town. Yet alpacas roam freely and flamingos seek out scarce water, both unexpected sights in this wild world.

The resembles something from a sci-fi film or another planet, but it’s right here on Earth, on the flanks of the world’s highest active volcano, 22,615-foot Ojos del Salado. Here, on the border of Argentina and Chile, a team of CU Boulder scientists seek to discover how tiny organisms persist at one of the driest and highest points on the planet.

This first-of-its-kind project may ultimately help inform the search for existing and extinct life on other planets.
