Lifeboat Foundation

Greg Brockman, President and Co-Founder of @OpenAI, joins Alexandr Wang, CEO and Founder of Scale, to discuss the role of foundation models like GPT-3 and DALL·E 2 in research and in the enterprise. Foundation models make it possible to replace task-specific models with those that are generalized in nature and can be used for different tasks with minimal fine-tuning.

In January 2021, OpenAI introduced DALL·E, a text-to-image generation program. One year later, it introduced DALL·E 2, which generates more realistic, accurate, lower-latency images with four times greater resolution than its predecessor. At the same time, it released InstructGPT, a large language model (LLM) explicitly designed to follow instructions. InstructGPT makes it practical to leverage the OpenAI API to revise existing content, such as rewriting a paragraph of text or refactoring code.

Ultra-pure diamond wafers could be used for quantum memory in tomorrow’s ultra-powerful quantum computers.

The Bulletin of the Atomic Scientists has a way of measuring the probabilities the human race will destroy itself through a nuclear holocaust. Due to recent geopolitical events, we are nearer to the brink of oblivion than at any other time in human history. Learn more about this serious subject with this video.

A proposed study of dwarf galaxies could give insight into whether dark matter particles interact with each other.

Thermodynamic phases governed by the strong nuclear force have been linked together using multiple theoretical tools.

Quantum chromodynamics (QCD) is the theory of the strong nuclear force. On a fundamental level, it describes the dynamics of quarks and gluons. Like more familiar systems, such as water, a many-body system of quarks and gluons can exist in very different thermodynamic phases depending on the external conditions. Researchers have long sought to map the different corners of the corresponding phase diagram. New experimental probes of QCD—first and foremost the detection of gravitational waves from neutron-star mergers—allow for a more comprehensive view of this phase structure than was previously possible. Now Tuna Demircik at the Asia Pacific Center for Theoretical Physics, South Korea, and colleagues have put together models originally used in very different contexts to push forward a global understanding of the phases of QCD [1].

Phase transitions governed by the strong force require extreme conditions such as high temperatures and high baryon densities (baryons are three-quark particles such as protons and neutrons). The region of the QCD phase diagram corresponding to high temperatures and relatively low baryon densities can be probed by colliding heavy ions. By contrast, the region associated with high baryon densities and relatively low temperatures can be studied by observing single neutron stars. For a long time, researchers lacked experimental data for the phase space between these two regions, not least because it is very difficult to create matter under neutron-star conditions in the laboratory. This difficulty still exists, although collider facilities are being constructed that are intended to produce matter at higher baryon densities than is currently possible.

Imagine the booming chords from a pipe organ echoing through the cavernous sanctuary of a massive, stone cathedral.

The sound a cathedral-goer will hear is affected by many factors, including the location of the organ, where the listener is standing, whether any columns, pews, or other obstacles stand between them, what the walls are made of, the locations of windows or doorways, etc. Hearing a sound can help someone envision their environment.

By plotting nonlinear trajectories through a GAN’s latent space, the method enables certain image attributes to vary while others are held fixed.

The observations could not be explained by Newton’s law of universal gravitation. An alternative theory of gravity might provide the answer. Astrophysicists observed mysterious behavior in star clusters that could lead to a rewrite of fundamental principles of the theory of gravity and even disprove the existence of dark matter, a press release explains.

The new findings challenge existing preconceptions based on widely-accepted principles from Newton’s law of universal gravitation, which explain the large-scale structure and movements of the universe.

China is the first country to operate a space station on its own.

China is one step closer to completing its space station after it launched the third and final module to orbit aboard a Long March 5B rocket, a Bloomberg report.

The rocket took off from Wenchang Satellite Launch Center on Hainan Island at 3:37 p.m. local time Monday, October 31. The payload it lifted to orbit is the Mengtian laboratory module, which will complete China’s orbital station. rocket took off from Wenchang Satellite Launch Center on Hainan Island at 3:37 p.m. local time Monday, October 31.
