  1. Cusp maintains a steady balance between their perky upbeat pop and fuzzy indie rock with a dash of shoegaze, keeping their focus on melodic charm and accessibility.

  2. A cycloidal pendulum - one suspended from the cusp of an inverted cycloid - is isochronous, meaning its period is constant regardless of the amplitude of the swing. Please find the proof using energy methods: Lagrange's equations (in the images attached to the reply).

    Background:
    The standard pendulum period of \(2\pi\sqrt{L/g}\) or frequency \(\sqrt{g/L}\) holds only for small oscillations. The frequency becomes smaller as the amplitude grows. If you want to build a pendulum whose frequency is independent of the amplitude, you should hang it from the cusp of a cycloid of a certain size, as shown in the gif. As the string wraps partially around the cycloid, the effect decreases the length of the string in the air, increasing the frequency back up to a constant value.

    In more detail:
    A cycloid is the path taken by a point on the rim of a rolling wheel. The upside-down cycloid in the gif can be parameterized by \((x, y)=R(\theta-\sin\theta, -1+\cos\theta)\), where \(\theta=0\) corresponds to the cusp. Consider a pendulum of length \(L=4R\) hanging from the cusp, and let \(\alpha\) be the angle the string makes with the vertical, as shown (in the proof).

  4. Delighted to share the next talk from Saturdays 2024 at the Centre for Urban Science and Progress (CUSP London), King’s College London!

    We had the pleasure of hosting Michael Hogers with talk titled "Modular Shiny(Proxy) - a SaaS Setup"

  9. "Early-career #researchers share their work on #microplastics and #health

    The #POLYRISK project is proud to work with a wide range of talented early-career researchers that are dedicating their scientific work on the impact of micro- and #nanoplastics on human health. In November 2023, early-career researchers within the #CUSP umbrella research cluster came together for a virtual exchange to share their research and ideas."

  10. While Keir Starmer was busy outlining his pro-growth agenda in Manchester, down the road, there was a gathering of activists, academics and social entrepreneurs cooking up a post-growth vision for food and real prosperity.

    I was privileged to be in the company of some great people today with inspiring presentations and even a chance to play with modelling clay and chalk!

    Thanks to @cusp_uk for hosting a valuable meeting of like minds today.

  11. 🌔 Über die folgenden 4 der 10 bei der #Artemis1 Mission ausgesetzten #Cubesats spricht die #NASA offiziell derzeit nicht:
    #LunIR sollte die Oberfläche des Mondes per Infrarot Aufnahmen vermessen; #NEAScout einen erdnahen Asteroiden erforschen; #OMOTENASHI auf dem Mond landen; #CuSP Sonnenpartikel vermessen - aber sie sind im Weltraum verschollen. Aus den Augen, aus dem Sinn. Mehr darüber in der Zeitschrift Cosmos:
