Reinforcement Learning Course — Full Machine Learning Tutorial

Posted by in categories: information science, policy, robotics/AI, space

This is NOT for ChatGPT, but instead its the AI tech used in beating GO, Chess, DOTA, etc. In other words, not just generating the next best word based on reading billions of sentences, but planning out actions to beat real game opponents (and winning.) And it’s free.


Reinforcement learning is an area of machine learning that involves taking right action to maximize reward in a particular situation. In this full tutorial course, you will get a solid foundation in reinforcement learning core topics.

New type of bolometer detector for far-infrared telescopes

Posted by in category: space

To study how stars and planets are born we have to look at star cradles hidden in cool clouds of dust. Far-infrared telescopes are able to pierce through those clouds. Conventionally, niobium nitride bolometers are used as the detectors, despite their low operating temperature of 4 Kelvin (−269° Celsius).

Now Yuner Gan (SRON/RUG), together with a team of scientists at SRON, TU Delft, Chalmers University and RUG, has developed a new type of bolometer, made of magnesium diboride, with an operating temperature of 20 Kelvin or above. This can significantly reduce the cost, complexity, weight and volume of the space instruments.

Conventional, superconducting niobium nitride (NbN) hot electron bolometers (HEBs) are so far the most sensitive heterodyne detectors for high-resolution spectroscopy at far-infrared frequencies. Heterodyne detectors take advantage of a local oscillator to convert a terahertz line into a gigahertz line.

Scientists observe high-speed star formation

Posted by in categories: physics, space

Gas clouds in the Cygnus X Region, a region where stars form, are composed of a dense core of molecular hydrogen (H2) and an atomic shell. These ensembles of clouds interact with each other dynamically in order to quickly form new stars. That is the result of observations conducted by an international team led by scientists at the University of Cologne’s Institute of Astrophysics and at the University of Maryland.

Until now, it was unclear how this process precisely unfolds. The Cygnus X region is a vast luminous cloud of gas and dust approximately 5,000 light years from Earth. Using observations of spectral lines of ionized carbon (CII), the scientists showed that the clouds have formed there over several million years, which is a fast process by astronomical standards. The results of the study, “Ionized carbon as a tracer for the assembly of interstellar clouds,” will appear in the next issue of Nature Astronomy.

The observations were carried out in an international project led by Dr. Nicola Schneider at the University of Cologne and Prof Alexander Tielens at the University of Maryland as part of the FEEDBACK program on board the flying observatory SOFIA (Stratospheric Observatory for Infrared Astronomy). The new findings modify previous perceptions that this specific process of star formation is quasi-static and quite slow. The dynamic formation process now observed would also explain the formation of particularly massive stars.

The Syntellect Hypothesis: The Most Probable Path to Our Future Transcendent Superintelligence

Posted by in categories: biological, chemistry, internet, robotics/AI, space

Could we imagine a world where our minds are fused together and interlinked with machine intelligence to such a degree that every facet of consciousness is infinitely augmented? How could we explore the landscapes of inner space, when human brains and synthetic intelligence blend together to generate new structures of consciousness? Is it possible to interpret the ongoing geopolitical events through the lens of the awakening Gaia perspective?

“When we look through the other end of the telescope, however, we can see a different pattern. We can make out what I call the One Mind — not a subdivision of consciousness, but the overarching, inclusive dimension to which all the mental components of all individual minds, past, present, and future belong. I capitalize the One Mind to distinguish it from the single, one mind that each individual appears to possess.” — Larry Dossey

Is humanity evolving into a hybrid cybernetic species, interconnected through the Global Mind? When might the Web become self-aware? What will it feel like to elevate our consciousness to a global level once our neocortices are fully connected to the Web?

Caltech to Launch Space Solar Power Technology Demo into Orbit in January

Posted by in categories: solar power, space, sustainability

In January 2023, the Caltech Space Solar Power Project (SSPP) is poised to launch into orbit a prototype, dubbed the Space Solar Power Demonstrator (SSPD), which will test several key components of an ambitious plan to harvest solar power in space and beam the energy back to Earth.

Space solar power provides a way to tap into the practically unlimited supply of solar energy in outer space, where the energy is constantly available without being subjected to the cycles of day and night, seasons, and cloud cover.
