What is Hawking radiation? Can black holes emit heat? Stephen Hawking published his theoretical prediction that radiation would be produced at the event horizon of a black hole in 1974, the same year he was elected a fellow of the Royal Society. “Hawking radiation” was named after him, since it was regarded as his theoretical discovery. Continue reading to learn about this theory.
How did the universe begin? What’s the evidence for the big bang? In the twentieth century, new scientific discoveries challenged the theory that the universe had always existed. Based on these discoveries, the “big bang” theory ultimately replaced the old model. In A Brief History of Time, physicist Stephen Hawking discusses the theory, the evidence for it, and its philosophical and theological implications. Keep reading for Hawking’s discussion of how the universe began.
Are black holes consistent with the second law of thermodynamics? Do they have entropy? For a time, scientists thought black holes had no entropy because they didn’t emit radiation. However, Stephen Hawking realized that, if black holes emit Hawking radiation, then they have a measurable temperature, and so their entropy can also be measured. Read more to learn about black hole thermodynamics.
What is quality information? How can you be more intentional about the quality of the information you consume? We’re bombarded with information and stimuli. The information you allow into your brain impacts your creativity and, ultimately, your productivity. You can increase the quality of information you take in by asking yourself five particular questions before you consume any information. Read more to learn how to find higher-quality information.
What’s Einstein’s theory of time? What’s the difference between special relativity and general relativity? Einstein’s theory of time encompasses his theories of special relativity and general relativity. In A Brief History of Time, physicist Stephen Hawking aims to explain this to a general audience. He discusses why time is relative as well as the implications of this relativity. Keep reading for Hawking’s insights.
What is the secret to productivity? How can focusing on a single task at a time help you become more productive? Most of us assume that the secret to productivity lies, at least in part, in managing our time better. But in Hyperfocus, Chris Bailey presents an alternate hypothesis: To focus in a world full of ever-increasing distractions, you must learn not just how to manage your time, but also how to manage your attention. Here is a brief overview of Hyperfocus by Chris Bailey.
What causes a black hole? How do we know black holes actually exist? In his book A Brief History of Time, Stephen Hawking discusses black holes—what they are, what causes them, and whether they actually exist. He also explores the possibility that primordial black holes exist, suggesting that black holes might have more than one cause. Read on to learn about black holes.
Do you get easily distracted? Do you know why your brain finds it hard to focus? Hyperfocus involves single-tasking for a prolonged period of time. Distractions, which Bailey defines as anything that diverts our attention from our original purpose, thwart our ability to hyperfocus. Therefore, limiting distractions is a critical part of hyperfocus. We’ll discuss just how bad we are at avoiding distractions and why.
Is space relative or absolute? What about motion? How are space and motion related to each other? In A Brief History of Time, physicist Stephen Hawking shares his insights on some of the major scientific discoveries of the twentieth century that deepened our knowledge of the universe. These insights include Hawking’s explanation of the relative nature of space and motion. He provides his analysis of ancient and modern theories. Continue reading to learn about Hawking’s insights on the relativity of space and motion.
When should you set aside time to focus? How long should your focus sessions last? Hyperfocus requires planning, according to productivity expert Chris Bailey. In his book Hyperfocus, he discusses scheduling focus sessions, using timers, setting deadlines, and spacing out tasks. He also writes about scheduling focus time within the context of biological and external realities. Read more to learn when and how to schedule a time to focus.
