THE ARGUMENT. “But that's hardly the end of the story; the complexity can increase far beyond the Planckian value. This is closely related to the fact that Hawking radiation for old black holes “wells up” out of exponentially small distances. I will argue that the right idea is not exponentially small‐distances, but rather exponentially large complexity.” https://onlinelibrary.wiley.com/doi/full/10.1002/prop.201500092?casa_token=8OO3b1OY4e4AAAAA%3ARqriAgTwtxnvsxl09CqnNy79m7l4ye7ZrkZxcLtObB9kHsTwYgzBuIV2X-xXQ7ezoR6VQPfQLCS-vnI View in LinkedIn

GRIST FOR THE MILL. “The subconscious mind is not merely a kind of deep seat repository of sunken memories and atavistic desires, but of forces which can, under special circumstances, manifest themselves in the physical world with a force which goes beyond anything which the conscious mind could command.” (Wilson, 1971:445). https://lnkd.in/d4sDpAu View in LinkedIn

COMPLEXITY GRADIENT. “Operators supported on the outer edge of the near‐horizon region—the onion skin—have the minimal complexity. As we peel the onion, the complexity increases. Eventually we get to the Planckian layer where the complexity has increased to a particular value .” 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

LAYERS OF THE ONION. “To understand the connection between complexity and black holes it is important to think of a black hole as an onion. The near‐horizon region of the black hole is a layered structure. Each layer has its own degrees of freedom. The CFT representation of the various layers differ in their degree of complexity.“ (CFT = Conformal field theory). https://onlinelibrary.wiley.com/doi/full/10.1002/prop.201500092?casa_token=8OO3b1OY4e4AAAAA%3ARqriAgTwtxnvsxl09CqnNy79m7l4ye7ZrkZxcLtObB9kHsTwYgzBuIV2X-xXQ7ezoR6VQPfQLCS-vnI View in LinkedIn

SWEET PREFERENCE. “By contrast, mice exhibit a strong preference for sucrose solution over H2O. Indeed, the consumed volume was significantly increased in line with the predilection of mice for sucrose solutions (Fig. 3b).” https://lnkd.in/dzPDm5w View in LinkedIn

FRAGMENT FROM NATURE continues from last weekend and concludes this weekend on a surprising paper showing that heavy water tastes different from normal water; given the subtlety of the difference, it is surprising and speaks to the exquisitely nuanced nature of taste receptors, that not only can they distinguish the small structural difference but can communicate that to the brain. An extraordinarily thorough paper. View in LinkedIn
