This book stirred up so many questions in me about black holes, the universe, God(s?), our existence and so on. You could almost insert a why question after every single sentence in this book. That is how I pleasantly suffered through reading it.<\/span><\/p>\n<p style=\"text-align: left;\"><i><span style=\"font-weight: 400;\">Can there really be a unified theory of everything?

Perhaps this has something to do with my own resignation that if the first possibility is true, there may be no meaning of my own work and existence if not towards that ultimate quest of finding that unified theory and I am neither a physicist nor an mathematician. I had to repeatedly seek comfort in hiking in the woods to think and to reconcile what I could do with my minuscule amount of knowledge and time on the earth (relatively speaking, totally negligible at the grand scheme of the universe). <\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"font-weight: 400;\">This is how 2017 ended and 2018 started: with a very long hike in the <\/span><a href=\"https:\/\/en.wikipedia.org\/wiki\/Santa_Cruz_Mountains\"><span style=\"font-weight: 400;\">Santa Cruz Mountains<\/span><\/a><span style=\"font-weight: 400;\">, and the thoughts provoked by two great books <\/span><i><span style=\"font-weight: 400;\">The Very Hungry Caterpillar<\/span><\/i><span style=\"font-weight: 400;\"> and <\/span><i><span style=\"font-weight: 400;\">The Theory of Everything<\/span><\/i><span style=\"font-weight: 400;\">, and the question what challenges to set for myself next. <\/span><\/p>\n<p style=\"text-align: left;\">\n","protected":false},"excerpt":{"rendered":"<p>During the holiday break, I read Stephen Hawking\u2019s The Theory of Everything.
