Paris 2024: Coordinating the Front-Crawl

Of all the swimming strokes humans have invented, none is faster or more efficient than the front-crawl. That's why all competitors use it in freestyle events, and why it's the only stroke that appears in races longer than 200 meters. But elite swimmers don't perform the front-crawl the same way in a sprint as they do in a longer race.  (Image credit: J. Chng; research credit: R. Carmigniani et al.)

Astronomy Daily - The Podcast: S03E173 Welcome to Astronomy Daily, your ultimate source for the latest in space and Astronomy news. I'm Anna, your host, and today we have an episode brimming with exciting updates from rocket launches to planetary exploration and cosmic mysteries. Highlights: - SpaceX Falcon 9's Return to Flight: The Federal Aviation Administration has authorized SpaceX to resume Falcon 9 flights following a previous malfunction. This clearance is timely for ESA's HERa mission, launching today, October 7, to study the impact of NASA's DaRt spacecraft on asteroid Dimorphos. This marks a significant step in international space collaboration. - Europa Clipper Mission Delay: NASA's $5 billion Europa Clipper mission faces a delay due to Hurricane Milton. Originally set for October 10, the launch is postponed with a window extending through November 6. Safety concerns have taken precedence, but the mission team is actively working on securing the spacecraft and reassessing launch options. - Nuclear Thermal Propulsion Advancements: Researchers are developing nuclear thermal propulsion technology that could halve travel time to Mars. By utilizing nuclear fission, this propulsion system promises more efficient space travel, potentially revolutionizing future crewed missions to the red planet. - BEPI Colombo's Mercury Philip: The Bepicolombo spacecraft's recent flyby of Mercury has provided new insights into the planet's magnetic field and plasma environment. These observations are paving the way for more detailed studies when Bepicolombo enters Mercury's orbit in 2026. - Origin of Sagittarius A: A new study suggests that the Milky Way's central supermassive black hole, Sagittarius A*, formed from a merger with another black hole around 9 billion years ago. This discovery sheds light on its rapid spin and misalignment with the Milky Way's angular momentum. - Concerns Over China's Qianfan Satellites: The brightness of China's Qianfan broadband constellation satellites is raising alarms among astronomers, potentially interfering with night sky observations. The astronomical community is calling for immediate action to address this issue as China plans to launch thousands more. For more space news, visit our website at astronomydaily.io.

Rempis / Adasiewicz / Abrams / Damon — Propulsion (Aerophonic)

The title of this recording is apt. Saxophonist Dave Rempis, vibraphonist Jason Adasiewicz, bassist Joshua Abrams, and drummer Tyler Damon sustain direction and momentum throughout its three lengthy tracks, which are excerpted from a concert that transpired on August 31, 2023 at Elastic Arts in Chicago. But it could just as easily be called Cusp, since it captures the precise moment when the quartet’s leader transitioned from one career phase characterized by intense community engagement to another that will focus upon articulating a mode of improvisational music-making that’s taken decades to develop.

Besides his dogged work as a musician and label proprietor, Rempis is an indefatigable organizer. He’s had a strong hand in the production end of the Hyde Park Jazz Festival and Pitchfork before that, and for 21 years he ran a weekly concert series presenting improvised music for the Elastic Arts Foundation. The latter affiliation came to an end the night that this music was played, when Rempis booked himself to play the final concert of his tenure with Elastic Arts. It fell on the same weekend as the Chicago Jazz Festival, which has often been an occasion when he would choose to play with one of his more enduring ensembles in some smaller venue after the main festival closes for the night. But this time he picked a new combo, albeit one with deep roots. Rempis, Adasiewicz, and Abrams are part of a cohort that came onto Chicago’s jazz scene in the 1990s, and they’ve been appearing on records together in varying combinations for nearly two decades. Damon and Rempis have been frequent collaborators since 2017, when their trio Kuzu (with Tashi Dorji) was first born on Elastic’s stage.

This web of associations is key to the character of the music on Propulsion. Everyone here understands what Rempis is after, and knows how to make it happen. The essence of his aesthetic is a convergence of the micro and macro. He’s committed to total improvisation. The music is made in the moment that is played, and the selection of personnel is his chief compositional decision. But that’s still very much a compositional act, since Rempis wants his improvisations to develop cohesive forms shaped by the imagination of every contributor. Even an unaccompanied passage, such as the incandescent, circular breathing-fueled four-minute line drawn by Rempis’ alto that opens “Egression,” is simply part of a larger, collectively conceived work. While his keening instrumental voice pushes forward, a calmer vibraphone melody wreathes it, and a seething maelstrom of bowed bass and Sisyphean drumming first fuels the progress and then resolves it as the music gently lands night quite fourteen minutes later.

Music like this doesn’t work unless all parties involved are tuned into each other from moment to moment. But it also requires musicians with sufficient recall where the music has recently been to make contributions that make sense as part of a larger developmental arc. While nothing quite matches the experience of being present when such music is being willed into existence, Propulsion comes close enough to deliver the feeling as well of the sound of committed co-creation.

Vehicles such as spaceships are still tricky for me but I needed to get this out of my head. This is my first concept art of an Orion Drive spacecraft. The Orion Drive is a spacecraft propulsion system conceived during the 1960s and involves the utilization of nuclear bombs to move spacecraft forward. Here's a video that summarizes this system and it's history: https://www.youtube.com/watch?v=6ntizB4Uc_0 The neat thing about this drive is that can be constructed with current technology and potentially reach speeds up to 9-11% the speed of light.

My design has several differences from the original concept. For one, it is significantly larger so to house several components such as a nuclear reactor (for creation propulsion bombs), rotating habitable drum, and large water reserves for cooling, radiation shielding, etc. Another difference is it has additional propulsion systems at the front and on it's side for deceleration and maneuvering respectively. Additionally, it as electric generators at the base of the shock absorbers so it can capture some of the force created by the propulsion and produce electricity.

I like to think of this as "Nuclear Steampunk" and it uses nuclear energy, electricity, and water, to power its technology. I'll need to do more research to refine this design (like seeing if it needs external thermal radiators) but this gives the base idea and it's one I might use in one of my projects. For now I'm going back to creature/alien design.

As always, comments and critiques are welcome.

Some classic Portal gel physics problem solving through a science sphere of yesteryear. Once we work out how to actually get into it that is, the maintenance on this place really went downhill after the whole neurotoxin thing and the old enrichment spheres were already badly neglected.

FAA update!! SpaceX poised to fly Starship again?

The FAA is not preventing the development of the Starship. If the spaceship can do half of what Elon Musk wants it to, the U.S. will have the ability to land armed forces and support on the other side of the world in less time to keep the peace. If the U.S. has a Starship that can carry nuclear-sized warheads, don’t worry; the Starship can fly sub-orbital above the country that dares to…
