    1. let me comment on your quantum physics i have only one objection please i think it's uh uh it's 01:01:21 what you said about the two uh sort of prototypical uh quantum puzzles which is schrodinger the double slit experiment uh it's uh it's perfect um my only objection is that in my book 01:01:34 i described of course i had a chapter about schrodinger cat but i don't use a situation in which the cat is dead or alive 01:01:46 i prefer a situation in which the cat is asleep or awake just because i don't like killing cats even in in in in mental experiments so after that 01:01:58 uh uh replacing a sleep cut with a dead cat i think uh i i i i completely agree and let me come to the the serious part of the answer um 01:02:10 what you mentioned as the passage from uh the third and the fourth um between among the the sort of the versions of 01:02:25 wooden philosophy it's it's exactly what i what i think is relevant for quantum mechanics for this for the following reason we read in quantum mechanics books 01:02:37 that um we should not think about the mechanical description of reality but the description reality with respect to the observer and there is always this notion in in books that there's observer or there are 01:02:50 paratus that measure so it's a uh but i am a scientist which view the world from the perspective of 01:03:02 modern science where one way of viewing the world is that uh there are uh you know uh billions and billions of galaxies each one with billions and billions of 01:03:14 of of of stars probably with planets all around and uh um from that perspective the observer in any quantum mechanical experiment is just one piece in the big story 01:03:28 so i have found the uh berkeley subjective idealism um uh profoundly unconvincing from the point 01:03:39 of view of a scientist uh because it there is an aspect of naturalism which uh it's a in which i i i grew up as a scientist 01:03:52 which refuses to say that to understand quantum mechanics we have to bring in our mind quantum mechanics is not something that has directly to do with our mind has not 01:04:05 something directly to do about any observer any apparatus because we use quantum mechanics for describing uh what happened inside the sun the the the reaction the nuclear reaction there or 01:04:18 galaxy formations so i think quantum mechanics in a way i think quantum mechanics is experiments about not about psychology not about our mind not about consciousness not 01:04:32 about anything like that it has to do about the world my question what we mean by real world that's fine because science repeatedly was forced to change its own ideas about the 01:04:46 real world so if uh if to make sense of quantum mechanics i have to think that the cat is awake or asleep only when a conscious observer our mind 01:05:00 interacts with this uh i say no that's not there are interpretations of quantum mechanics that go in that direction they require either am i correct to say the copenhagen 01:05:14 school does copenhagen school uh talk about the observer without saying who is what is observed but the compelling school which is the way most 01:05:27 textbooks are written uh describe any quantum mechanical situation in terms okay there is an observer making a measurement and we're talking about the outcome of the measurements 01:05:39 so yes it's uh it assumes an observer but it's very vague about what what an observer is some more sharp interpretation like cubism uh take this notion observer to be real 01:05:54 fundamental it's an agent somebody who makes who thinks about and can compute the future so it's a it's a that's that's a starting point for for doing uh for doing the rest i was 01:06:07 i've always been unhappy with that because things happen on the sun when there is nobody that is an observer in anything and i want to think to have a way of thinking in the world that things happen there 01:06:20 independently of me so to say is they might depend on one another but why should they depend on me and who am i or you know what observers should be a you know a white western scientist with 01:06:32 a phd i mean should we include women should we include people without phd should we include cats is the cat an observer should we fly i mean it's just not something i understand

      Carlo goes on to address the fundamental question which lay at the intersection of quantum mechanics and Buddhist philosophy: If a tree falls in the forest, does anybody hear? Carlo rejects Berkeley's idealism and states that even quantum mechanical laws are about the behavior of a system, independent of whether an observer is present. He begins to invoke his version of the Schrödinger cat paraodox to explain.

    1. When I was around eight years old, having recently made the trip with my family back ‘home’ to London from where I was born and lived my earliest years in Nairobi, Kenya, I contracted measles, the first of many childhood illnesses that confined me to bed and disrupted my schooling. My father sat by my bedside and read stories to me about the planets and outer space, infecting me with his love of scientific exploration. I was given books to read about natural history and I learned to identify the garden birds in the tree that grew outside my bedroom window. I made watercolour paintings of these and others that I had never seen from illustrations on the pages of ‘Collins Pocket Guide to British Birds’. Then, whenever I was well enough, I was taken out into the countryside and spent many happy days bird-spotting for myself. I was taken on my first ‘fungus foray’ to a place called Burnham Beeches, west of London. It was led by the redoubtable figure of a man called Bayard Hora and I was awestruck by what I many years later described as ‘The Fountains of the Forest’ as they erupted from ground and trees in manifold shapes and colours, not least the legendary ‘fly agaric’ (Amanita muscaria), the ‘parasol’ (Macrolepiota procera) and numerous ‘brittle gills’ (Russula spp). I found that their Latin names came easily to me and I delighted in showing off my recall to peers and teachers.

      When we are young and provided with such opportunity to marvel and immerse ourselves in the patterns of nature, we keep the creative flow alive.

    1. Big talk. But Agnes is dead. And I don’t know if you heard, but your little woodland circle’s been broken. So I don’t really see, anything getting in my way, if I wanted to burn the flesh, off your snarky bones.

    1. Burn bosses in California can more easily be held liable than their peers in some other states if the wind comes up and their burn goes awry. At the same time, California burn bosses typically suffer no consequences for deciding not to light.
    2. Much of the fire-suppression apparatus — the crews themselves, the infrastructure that supports them — is contracted out to private firms. “The Halliburton model from the Middle East is kind of in effect for all the infrastructure that comes into fire camps,” Beasley said, referencing the Iraq war. “The catering, the trucks that you can sleep in that are air-conditioned…”
    3. “The median compensation package — including base pay, special pay, overtime and benefits — for full time Cal Fire firefighters of all categories is more than $148,000 a year.”
    4. A six-word California fire ecology primer: The state is in the hole. A seventy-word primer: We dug ourselves into a deep, dangerous fuel imbalance due to one simple fact. We live in a Mediterranean climate that’s designed to burn, and we’ve prevented it from burning anywhere close to enough for well over a hundred years. Now climate change has made it hotter and drier than ever before, and the fire we’ve been forestalling is going to happen, fast, whether we plan for it or not.
    1. In such a manner, then, the three universal institutions instantiate the three temporal ecstasies which, properly speaking, define humanity’s abode on the earth. Religion, matrimony, and burial of the dead embody the linear openness of time. Religion is born of the idea of providence. It implies an awareness of the future. Burial of the dead is grounded in reverence for the past, for the ancestral, in short for what we call tradition. Tradition comes to us from the domain of the dead. Both religion and burial, in turn, serve to consolidate the contract of matrimony, which mantains the genealogical line in the present.

      Contextualize: This passage is about the beginnings of Humanism and the forest as a subject or element that caused the appearance of what we know as civilization. The scene takes place in the West, in a landscape abundant with forests in all directions, in which the people who inhabited it were lonely, without parents, or responsibilities, nothing. They lived a life without rules or restrictions, what the author describes as "bestial freedom." They visualized the space in a horizontal sense, because the density of the forests did not let them see more. The forest respresented the unknown.

      As everything in nature is part of a cycle, forests dry up and between darkness, light passes through and creating the idea that there is something else than the forest, that's when the giants become aware of the sky and visualize the space vertically. Thus was born the first act of human enlightenment: forest clearing and the appropiation of it for the creation of the three human institutions: religion, matrimony and buried of the dead. The forest becomes the obstacle and threat to the progress of the human being.

    1. RF is now a standard to effectively analyze a large number of variables, of many different types, with no previous variable selection process. It is not parametric, and in particular for survival target it does not assume the proportional risks assumption.

    1. Of Colombia's total area of 282 million acres, 148 million are forested. The Colombian government has established the goal of expanding that area by reclaiming 2.7 million acres. The country's timber needs have largely been filled by imports.

      148 million acres are forested.

    1. He expects that the logging project near Quimby’s land will likely generate about $755,250 at the state’s average sale price, $50.35 per cord of wood. The land has about 1,500 harvestable acres that contain about 30 cords of wood per acre, or 45,000 cords, but only about a third of that will be cut because the land is environmentally sensitive, Denico said. The Bureau of Parks and Lands expects to generate about $6.6 million in revenue this year selling about 130,000 cords of wood from its lots, Denico said. Last year, the bureau generated about $7 million harvesting about 139,000 cords of wood. The Legislature allows the cutting of about 160,000 cords of wood on state land annually, although the LePage administration has sought to increase that amount.

    1. from plantations. If that were to increase to 75 percent, the logged area of natural forests could drop in half.” Meanwhile the consumption of all wood has leveled off---for fuel, buildings, and, finally, paper. We are at peak timber.
