Emergence, a fascinating and complex concept, illuminates how intricate patterns and behaviors can spring from simple interactions. It’s akin to marveling at a symphony, where each individual note, simple in itself, contributes to a rich, complex musical experience far surpassing the sum of its parts. Although definitions of emergence vary across disciplines, they converge on a common theme: small quantitative changes in a system’s parameters can lead to significant qualitative transformations in its behavior. These qualitative shifts represent different “regimes” where the fundamental “rules of the game”-the underlying principles or equations governing the behavior-change dramatically.
To make this abstract concept more tangible, let’s explore relatable examples from various fields:
1. Physics: Phase Transitions: Emergence is vividly illustrated through phase transitions, like water turning into ice. Here, minor temperature changes (quantitative parameter) lead to a drastic change from liquid to solid (qualitative behavior). Each molecule behaves simply, but collectively, they transition into a distinctly different state with their properties.
A team of researchers led by the University of California San Diego has developed a soft, stretchy electronic device capable of simulating the feeling of pressure or vibration when worn on the skin. This device, reported in a paper published in Science Robotics (“Conductive block copolymer elastomers and psychophysical thresholding for accurate haptic effects”), represents a step towards creating haptic technologies that can reproduce a more varied and realistic range of touch sensations.
The device consists of a soft, stretchable electrode attached to a silicone patch. It can be worn like a sticker on either the fingertip or forearm. The electrode, in direct contact with the skin, is connected to an external power source via wires. By sending a mild electrical current through the skin, the device can produce sensations of either pressure or vibration depending on the signal’s frequency.

JACKSONVILLE, Fla. (June 17, 2024) – Redwire Corporation (NYSE: RDW), a leader in space infrastructure for the next generation space economy, announced today that it has been awarded a contract from the Defense Advanced Research Projects Agency (DARPA) to be the prime mission integrator for the development of a revolutionary air-breathing satellite that will demonstrate the use of novel electric propulsion systems in very low-Earth orbit (VLEO) using Redwire’s SabreSat VLEO platform. The program leverages Redwire’s worldwide leadership in developing and providing VLEO capabilities.
The strategic significance of VLEO is growing – especially for national security missions. While low-Earth (LEO) and geosynchronous (GEO) orbits are becoming increasingly congested and contested, spacecraft in VLEO operate in a relatively unimpaired environment. Bridging the gap between air and space, VLEO spacecraft fly above airborne anti-access areas while operating significantly closer to the area of responsibility on the ground than existing satellites. Additionally, unlike LEO and GEO, debris in VLEO deorbits in hours or days rather than in decades or more.
“We are proud to be leveraging our SabreSat satellite design to support critical VLEO technology advancements for DARPA’s game-changing Otter program,” said Spence Wise, Redwire Senior Vice President, Missions and Platforms. “As VLEO emerges as a critical domain for national security missions, Redwire is continuing to make investments to support technology innovation and strategic operations in this environment.”

Landing on the moon is difficult due to its uneven surface and the presence of #regolith, a layer of loose, fragmented material. Regolith is problematic because it can damage equipment and pose safety risks during landings. Using regolith to create bricks for building landing pads is a smart use of in situ resource utilization, reducing the need to transport materials from Earth. Astroport Space Technologies in San Antonio, Texas, is developing technology to manufacture these regolith bricks, aiming to create safe, durable landing sites on the moon.
