Humanity’s Babel Tower: Space Elevator

Posted by in categories: business, space travel

In the book of Genesis, the Bible recounts the Babel tower that, once built, would allow humanity to do whatever it wishes. In this video, I will go over how humanity’s first space elevator will revolutionize human progress in space exploration and colonization. I will also go over the risks of a possible space elevator.

Quiet Anthropocene, quiet Earth

Posted by in category: biotech/medical

Our planet vibrates incessantly, sometimes with notable but more often with imperceptible intensity. Conventional seismology attempts to decipher vibrational sources and path effects by studying seismograms—records of vibrations measured with seismometers. In doing so, scientists seek either to understand the tectonic processes that lead to strong ground motions and earthquake failure (1) or to probe otherwise inaccessible planetary interiors (2). Progress in these areas of research typically has relied on the rare and geographically irregular occurrence of large earthquakes. However, anthropogenic (human) activities at Earth’s surface also generate seismic waves that instruments can detect over great distances. On page 1338 of this issue, Lecocq et al. (3) report on a quieting of anthropogenic vibrations since the start of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic.

OpenAI ‘GPT-f’ Delivers SOTA Performance in Automated Mathematical Theorem Proving

Posted by in categories: mathematics, robotics/AI

San Francisco-based AI research laboratory OpenAI has added another member to its popular GPT (Generative Pre-trained Transformer) family. In a new paper, OpenAI researchers introduce GPT-f, an automated prover and proof assistant for the Metamath formalization language.

While artificial neural networks have made considerable advances in computer vision, natural language processing, robotics and so on, OpenAI believes they also have potential in the relatively underexplored area of reasoning tasks. The new research explores this potential by applying a transformer language model to automated theorem proving.

Automated theorem proving tends to require general and flexible reasoning to efficiently check the correctness of proofs. This makes it an appealing domain for checking the reasoning capabilities of language models and for the study of reasoning in general. The ability to verify proofs also helps researchers as it enables the automatic generation of new problems that can be used as training data.

Linking calorie restriction, body temperature and healthspan

Posted by in categories: biotech/medical, food, life extension, neuroscience

Cutting calories significantly may not be an easy task for most, but it’s tied to a host of health benefits ranging from longer lifespan to a much lower chance of developing cancer, heart disease, diabetes and neurodegenerative conditions such as Alzheimer’s.

A new study from teams led by Scripps Research Professors Bruno Conti, Ph.D., and Gary Siuzdak, Ph.D., illuminates the critical role that temperature plays in realizing these diet-induced health benefits. Through their findings, the scientists pave the way toward creating a medicinal compound that imitates the valuable effects of reduced body temperature.

In the last video in this series we discussed the differences between deep learning and machine learning, how and when the field of deep learning was officially born, and it’s rise to mainstream popularity. The focus of this video then will be on artificial neural networks, more specifically – their structure.

How to Give A.I. a Pinch of Consciousness

Posted by in category: robotics/AI

In 1998, an engineer in Sony’s computer science lab in Japan filmed a lost-looking robot moving trepidatiously around an enclosure. The robot was tasked with two objectives: avoid obstacles and find objects in the pen. It was able to do so…
