How We Came to Know the Cosmos: Light & Matter

Description:One out of every five stars in the night sky may contain habitable planets. The universe is both infinite and ever expanding, and there may be at least nine dimensions. On top of this, there may be infinities upon infinities of other universes. In fact, every person on Earth may have an infinite amount of 'parallel-selves'.Modern science has become so astounding that many people find it hard to believe. How we came to know the cosmos addresses this by showing how we came to such bizarre conclusions. In order to really understand the universe you live in, you need to start at the beginning.How we came to know the cosmos explains the simple discoveries made in prehistoric times, and how we built on them, little by little, until the conclusions of modern theories seem obvious and inevitable.How we came to know the cosmos is a two-part series of illustrated popular science books composed of How We Came to Know the Cosmos: Space & Time and How We Came to Know the Cosmos: Light & Matter. How We Came to Know the Cosmos: Space & Time looks outwards, describing how we have come to understand our place in the universe and How We Came to Know the Cosmos: Light & Matter looks inwards, asking what we are made of.How We Came to Know the Cosmos: Light & Matter looks at how people thought light is a wave - something that can be split into an infinite amount of parts - and that everything else is made of atoms - something that has a fixed, finite size.By the end of the 1800s, people realised that light is made of electromagnetic waves, most of which are invisible to us. Elements were found to be made of atom-like objects, which appeared to contain smaller particles like electrons. Elements seemed to exhibit periodic behaviour when they were arranged from lightest to heaviest.In the 1900s, scientists saw that waves can sometimes act like atoms, and atoms can sometimes act like waves. Following the work of de Broglie in 1924, people showed that all types of matter can act like waves, which means that even people can be described with a wavelength. This led to the development of quantum mechanics, which shows that everything can be described with a wave equation.The structure of atoms were explained further in the 1920s, when Bohr and Sommerfeld described how heavier atoms have more electrons, which are arranged in shells around the atom's nucleus. Elements are more reactive if they are closer to having a full outer electron shell, and this explained the periodic behaviour of elements.Protons and neutrons were discovered in the centre of atoms, and it was shown that these are made of smaller particles, known as quarks, in the latter half of the 1900s when the 'standard model' of particle physics was developed. By the end of the 1900s, all matter and all forces apart from gravity could be explained using quantum field theories.At the same time, philosophers tried to explain how matter can be capable of thought. In the 1800s, people began to consider that the mind is the same as the brain, but they were unable to explain why we have subjective experiences. We might both see the same wavelengths of light, for example, but how do we know we see the same colour?In the 1900s, people argued that quantum mechanics is the first scientific theory that explains why we have subjective experiences. This is known as the many worlds approach to quantum mechanics. The many worlds approach predicts that we live in a multiverse, with an infinite amount of parallel worlds in the same spacetime as our own.We have made it easy for you to find a PDF Ebooks without any digging.
