MEASUREMENT INTERVAL. “The time to achieve this degree of complexity is of order the classical recurrence time. Once this much time has elapsed the complexity stops increasing, although it may fluctuate.” https://onlinelibrary.wiley.com/doi/full/10.1002/prop.201500092?casa_token=8OO3b1OY4e4AAAAA%3ARqriAgTwtxnvsxl09CqnNy79m7l4ye7ZrkZxcLtObB9kHsTwYgzBuIV2X-xXQ7ezoR6VQPfQLCS-vnI View in LinkedIn

GRAVITY AND COMPKEXITY. “I want to suggest that there may be another deep connection; this time between gravity and complexity. To state it as a slogan: Things fall because there is a tendency toward complexity.” https://onlinelibrary.wiley.com/doi/full/10.1002/prop.201500092?casa_token=8OO3b1OY4e4AAAAA%3ARqriAgTwtxnvsxl09CqnNy79m7l4ye7ZrkZxcLtObB9kHsTwYgzBuIV2X-xXQ7ezoR6VQPfQLCS-vnI View in LinkedIn

COMPLEXITY AND ENTROPY. “Let's begin with the fact that complexity satisfies a law similar to the second law of thermodynamics. It tends to increase, but with caveats that are similar to those that apply to the increase in entropy.” https://onlinelibrary.wiley.com/doi/full/10.1002/prop.201500092?casa_token=8OO3b1OY4e4AAAAA%3ARqriAgTwtxnvsxl09CqnNy79m7l4ye7ZrkZxcLtObB9kHsTwYgzBuIV2X-xXQ7ezoR6VQPfQLCS-vnI View in LinkedIn

ORDER DERIVATIVES. “Aristotle's theory of gravity was first‐order in derivatives; force is equal to mass times velocity. The complexity‐based theory looks more like a second order theory because complexity and it's rate of change are independent variables.” https://onlinelibrary.wiley.com/doi/full/10.1002/prop.201500092?casa_token=8OO3b1OY4e4AAAAA%3ARqriAgTwtxnvsxl09CqnNy79m7l4ye7ZrkZxcLtObB9kHsTwYgzBuIV2X-xXQ7ezoR6VQPfQLCS-vnI View in LinkedIn

ZERO DERIVATIVE. “The complexity can be large, but have zero time‐derivative. If evolved forward or backward the complexity will increase.” https://onlinelibrary.wiley.com/doi/full/10.1002/prop.201500092?casa_token=8OO3b1OY4e4AAAAA%3ARqriAgTwtxnvsxl09CqnNy79m7l4ye7ZrkZxcLtObB9kHsTwYgzBuIV2X-xXQ7ezoR6VQPfQLCS-vnI View in LinkedIn

COMPLEXITY FLUX. “If the complexity is not stationary it will either increase or decrease. If it increases it will continue to increase, but if it decreases that will not last long. It will reach a minimum and turn around.” https://onlinelibrary.wiley.com/doi/full/10.1002/prop.201500092?casa_token=8OO3b1OY4e4AAAAA%3ARqriAgTwtxnvsxl09CqnNy79m7l4ye7ZrkZxcLtObB9kHsTwYgzBuIV2X-xXQ7ezoR6VQPfQLCS-vnI View in LinkedIn

“FIREWALLS, like reversals of the second law, can occur in one of two ways; either by the action of an extremely complex operation needed to locally reverse the arrow of time, or by bottling up the system for a classical recurrence time. Temporary firewalls can also form if black holes are formed over long time periods.” https://onlinelibrary.wiley.com/doi/full/10.1002/prop.201500092?casa_token=8OO3b1OY4e4AAAAA%3ARqriAgTwtxnvsxl09CqnNy79m7l4ye7ZrkZxcLtObB9kHsTwYgzBuIV2X-xXQ7ezoR6VQPfQLCS-vnI View in LinkedIn

THIS DIFFICULT PAPER is a sampling of the extraordinary thinking that physicists studying complexity and black holes are engaged in, and how purely mathematical and logical operations are being used to dissect the possibilities within such an inscrutable object. An exceptionally interesting and challenging paper. https://onlinelibrary.wiley.com/doi/full/10.1002/prop.201500092?casa_token=8OO3b1OY4e4AAAAA%3ARqriAgTwtxnvsxl09CqnNy79m7l4ye7ZrkZxcLtObB9kHsTwYgzBuIV2X-xXQ7ezoR6VQPfQLCS-vnI View in LinkedIn

BLIND MAN’S BUFF. “We’re playing Russian roulette, with a gun pointed at our children, with five bullets instead of just one in the chamber, and we go on pulling the trigger until it goes off. That’s basically what climate and nature breakdown are.” https://lnkd.in/gNpHt_C View in LinkedIn
