Entropy and the Arrow of Time | Peter Stockil | TEDxKings College School
TEDx Talks· 2025-11-07 16:27
The universe is falling apart and it has been since the beginning of time. This all comes down to one thing. Entropy, the measure of disorder.Consider a jar of bees. All safely contained under the lid. Together they are compact and organized.Great at making honey. But now say I unscrewed that lid. Watch as the bees fly all over the space.Some will go backstage. Some will fly underneath the seats. Some will even find their way out of here.Suddenly, they're impossible to collect back up, and they're no good a ...
The hidden physics of life | Nikta Fakhri | TEDxNewEngland

Core Concepts - The industry highlights the distinction between equilibrium, a state of balance and stability, and non-equilibrium, where life thrives due to constant motion and energy consumption [3][6][9] - The industry emphasizes that life exists far from equilibrium, where systems are dynamic and perpetually consume energy [6][9] - The industry notes that symmetry breaking, an ongoing process driven by energy flow, leads to diversity and adaptability in living systems [10][12] Emergence and Complexity - The industry points out that emergence in non-equilibrium systems is dynamic and ongoing, creating feedback loops that maintain the system far from equilibrium [14] - The industry observes that non-equilibrium principles manifest across all scales of life, from murmuration to single living cells [16][17] - The industry indicates that protein patterns in cells behave like charged particles, orchestrating developmental processes [18] Time and Entropy - The industry states that living systems break the symmetry of time itself, creating an irreversible direction linked to energy flow and entropy [19][21] - The industry quantifies the arrow of time using entropy, a measure of disorder, which increases with higher energy flows in living systems [21][22] Applications and Implications - The industry suggests exploring the use of non-equilibrium physics principles to design smarter, more adaptable materials and discover sustainable energy solutions [24] - The industry proposes looking for the origins of life in environments with high energy fluxes, potentially discovering new forms of life [24][25]
How Will the Universe End? | Beatrice Gironi | TEDxFrancisHollandSchoolSloaneSquare

[Applause] We've always been fascinated with the end. Whether it's the apocalypse in blockbuster movies, fears about climate change, or warnings about artificial intelligence taking over the world. Humanity has a deep, almost instinctive obsession with how things might fall apart.These endings may seem significant to us, perhaps even frightening. But consider the possibility that these are merely minor conclusions, temporary localized events within a much broader continuum. If we zoom out, we come face to f ...
