Long talks on science and philosophy; claims trace to papers and experiments
1:15:16Time Is Not an Illusion: Irreversibility Runs Deeper Than Time-Symmetric Equations
Jim Al-Khalili argues that time is real and directed, and that irreversibility is more fundamental than time-symmetric equations; he also proposes replacing thermodynamic entropy with quantum entanglement entropy as the basis of the past hypothesis.
1:05:36Black Holes Have Only Two Parameters, but How They Form Is Still a Mystery
Gravitational waves and the EHT confirm that black holes really do have only two parameters, but how a 120-solar-mass black hole forms, whether dark matter is made of tiny black holes, and how the last parsec gets crossed all remain unsolved.
1:16:23Science is not a warehouse of answers but a structured inquiry into ‘what we don't know’
Science is not a warehouse of facts but a structured interrogation of what we do not know; failure is the normal condition and uncertainty is the hallmark. What the public really needs to learn is how to ask a good question.
1:51:36LLMs Are Not Autocomplete — They Are Our Cognitive Cousins
LLMs are not fancy autocomplete but ‘cognitive cousins’ that share core principles with human cognition: attention mechanisms recreate production systems, and prediction is the dominant training signal; sample efficiency is three to four orders of magnitude worse, but an architectural change may close the gap.
