From the beginning the post-apocalyptic world it presents is so bleak that, quite honestly, one questions whether why one would bother to rebuild a civilisation that might only repeat the same mistakes and so perhaps seek other more limited ways of survival with less technology. About: The London Knowledge School is an extremely encouraging, friendly, welcoming, inclusive school to learn the Knowledge of London. We are based in Grays, Essex near the A13 and M25. Also, these peaceful souls will spend their time loving animals, not hunting and eating them. In one place, Dartnell grudgingly admits that rebuilding medicine “may also call for disagreeable practices like animal testing.” I’m pretty sure the inhabitants of post-apocalyptic Earth won’t be much concerned with animal welfare, other than preparatory to their consumption. The book is split into sections dealing with aspects such as agriculture, medicine, power, construction and more advance scientific methods. It’s not just a survival guide but a reminder of how much we take for granted. Josh had recently shown me the TED Talk for the guy who tried to build a toaster from scratch. Just knowing how it works is not enough but you need to know how to mine and extract the base materials required first. This book is very much on that premise, how even simple things will be much more difficult.

A rather disappointing book, 'The Knowledge' purports to give us the basics for the survival of civilisation in the wake of an apocalypse based on some slightly dubious assumptions about what actually survives of humanity and in what condition. Whichever licence you choose to apply for, you will have to accumulate an encyclopedic knowledge of the streets and places of interest in that area. This will prove you can navigate your way around the Capital. Qué pasaría en los primeros meses? ¿Qué hay que hacer? Lo primero, buscar cobijo, alimentos y agua. Necesitaremos 3 litros de agua por día. Nos explica cómo filtrar el agua con carbón vegetal y arena. También las botellas de agua servirán, y mejor al sol para esterilizarlas. El pegamento nos servirá para cerrar heridas. En cuanto a comida, un super nos durará 55 años, con las latas y conservas. La gasolina no durará tanto, 10 años máximo. También explica que hay que ir a un campo de golf para buscar las baterías de los cochecitos, alternadores de coches para disponer de generadores eléctricos. Los plásticos, mejor PET.El siguiente capítulo es sobre medicina. El peligro más relevante en un mundo postapocalíptico es la infección, por lo que seguirá siendo importante lavarse las manos. Para el cólera, el tratamiento es evitar la deshidratación, por lo que hay que beber mucha agua. Habrá que inventar el forceps, para ayudar a dar a luz. El estetoscopio, y ya para nota los rayos x. Si hay que hacer cirugía, las tres As: anatomía, asepsia, anestesia. Por último explica como hacer penicilina. No sabía que era tan laborioso. Lewis' writing is succinct,accurate and informative. His ability to refine a concept down to one or two sentences that manages to convey exactly how a thing works and why it does what it does is astounding. This is what all educators and science communicators strive for and it seems like he as a great talent. When he was explaining concepts that I have previously learnt I was amazed at the clarity of which he would convey the ideas. How easily can you explain how refrigerators work using the laws if thermodynamics? Dartnell then stealthily drew me into a detailed history of science and engineering, with a strong emphasis on the world's chemical underpinnings. I must confess that I didn't follow all of it, but when I took the time to walk through his explanations, I got a ton out of them.

About: Established in 1985, Knowledge Point is London's most central and well established Knowledge school. We are placed between Kings Cross and Caledonian Road Station. We have online classes and facilities to accommodate all levels of Knowledge students and our teachers are not only qualified taxi drivers but qualified teachers also. This is where time comes into play. If we assume a population that doubles in each generation (each couple have four children who survive into child bearing age), then it will take 24 generations for the population to return to 65 million. That would be between 500 and 600 years, assuming no return of the events that caused the catastrophe. Is this credible? I don't think so. I believe that over the course of half a millennia society would develop in ways that we could not imagine from the perspective of today. The author assumes that society is a constant input factor, where experience suggests that it isn't.Some readers might find the advanced chemistry section a bit of a drudge, but I can’t see how Dartnell could avoid that, given leaving it out would undermine the book’s purpose. On the flip side, it provides useful context for any fledgling chemistry students. My own field of research, in astrobiology, is engaged in the search for life beyond the Earth. In some ways this is one of the newest areas of science, made possible with recent developments in our understanding of the limits of life on Earth, our capability in building sophisticated robotic probes to explore the other planets and moons in our solar system, and space-based telescopes able to spot new worlds orbiting other stars in the galaxy. But in one sense it’s also one of the most ancient forms of human inquiry – the ages-old curiosity with whether we are alone in the universe, or perhaps there are beings somewhat like us out there within the twinkling heavens. Me ha divertido este libro en tiempos de cuarentena por el COVID-19, y coincide bastante con la apreciación de que en las sociedades modernas hemos perdido mucho del conocimiento básico que nos ayudaría a iniciar una civilización desde cero. One wonders if one of the influential texts driving this book (it is cited in the reading list) is Walter Miller's classic scifi novel 'A Canticle for Leibowitz' because at times it reads like a response to that book's thesis of science lost to faith. It is a quarrel started as a first strike on faith.
