    #192: Lasers 101, Particle Physics & Nonlinear Optics ft. G. Ravindra Kumar

    How do lasers work, and how can extreme laser light be used to study matter at the most fundamental level? In Know Time Episode 192, physicist G. Ravindra Kumar takes us from the basics of lasers to the cutting edge of nonlinear optics, intense light-matter interactions and particle physics. We explore how lasers generate and control light, what happens when extremely intense laser pulses interact with matter, and how these interactions can create extraordinary conditions that help scientists investigate fundamental physics. The conversation also explores nonlinear optics, high-intensity lasers, plasma physics, particle acceleration and laboratory experiments that recreate extreme, star-like conditions. If you're interested in lasers, quantum physics, particle physics, optics, plasma physics and how extreme light can reveal the fundamental nature of matter, this episode offers an accessible introduction to the science behind these experiments. 🎙️ Guest: G.

    #190: Fantasy Architecture, Dharavi Redevelopment & Philosophy of Architecture ft. Mustansir Dalvi

    What does architecture tell us about power, inequality, cities and the way we imagine the future? In this episode of Know Time, architect, poet and writer Mustansir Dalvi joins us for a wide-ranging conversation about architecture, philosophy, Dharavi redevelopment and the idea of “fantasy architecture.” We explore how buildings and cities reflect social structures, Casa Battlo in Barcelona, the Dancing House in Prague, the Blur Building, Fish Building in Hyderabad, who gets to imagine and design the future of a city, and what happens when architectural visions collide with the lived realities of the people who inhabit them. We discuss Dharavi redevelopment, Mumbai, urban planning, architecture and inequality, the philosophy of architecture, speculative and fantasy architecture, public space, housing, displacement, and the relationship between architecture and power. Mustansir Dalvi brings together architecture, literature and philosophy to ask a deeper question: when we design cities, are we simply designing buildings, or are we designing society itself? Watch the full conversation for an exploration of architecture, urbanism, Mumbai and the politics of space.

    #189: Black Holes, String Theory, Quantum Physics & Gravity ft. Shiraz Minwalla

    What happens when the laws of quantum physics meet the most extreme objects in the universe? In this episode of Know Time, theoretical physicist Shiraz Minwalla takes us deep into the world of black holes, quantum mechanics, string theory, quantum gravity, and the fundamental structure of reality. We explore some of the biggest questions in modern theoretical physics: What actually happens inside a black hole? Why is it so difficult to reconcile quantum mechanics with Einstein’s theory of general relativity? Could string theory provide a path toward a theory of quantum gravity? And what can black holes teach us about space, time, information, and the universe itself? Shiraz Minwalla is a leading theoretical physicist whose work spans string theory, quantum field theory, gravity, black holes, and mathematical physics. In this conversation, he explains these difficult ideas in an accessible way while exploring where our understanding of fundamental physics currently stands. Topics covered include: • Black holes and the black hole information paradox • Quantum mechanics and general relativity • String theory and quantum gravity • Quantum field theory • The nature of space and time • Hawking radiation • The holographic principle • The AdS/CFT correspondence • What happens inside black holes • The deepest unanswered questions in theoretical physics 🎙️ Guest: Shiraz Minwalla 🎧 Podcast: Know Time 📺 Episode: Know Time 189 Shiraz: https://www.infosysprize.org/laureates/2013/shiraz-naval-minwalla.html SUPPORT: Patreon: https://www.patreon.com/knowtime Anchor: https://anchor.fm/knowtime/support Youtube Membership: https://www.youtube.com/channel/UCJ-937lA3_s2g5AxdpKQjVg/join Merch: https://know-time-shop.fourthwall.com/ PODCAST: Anchor: https://anchor.fm/knowtime Spotify: https://open.spotify.com/show/2CjRJPktODLDeHavCNDLGA Apple Podcasts: https://podcasts.apple.com/us/podcast/know-time/id1535371851?uo=4 CONNECT: Youtube: Subscribe!
