 Space is Negative Energy

The great mystery at the heart of the Big Bang is to explain how an entire, fantastically enormous universe of space and energy can materiahse out of nothing. The secret lies in one of the strangest facts about our cosmos. The laws of physics demand the existence of something called "negative energy." To help you get your head around this weird'd but crucial concept, let me draw on a simple analogy Imagine a man wants to build a hill on a flat piece of land. The hill will represent the univ...

 Entropy in our Everyday Lives: Active Stability

Because things naturally move to disorder over time, we can position ourselves to create stability. There are two types of stability: active and passive. Consider a ship, which, if designed well, should be able to sail through a storm without intervention. This is passive stability. A fighter jet, in contrast, requires active stability. The plane can’t fly for more than a few seconds without having to adjust its wings. This adjustment happens so fast that it’s controlled by software. Ther...

 Mental States in Gamer Mastery

Learning State While in the learning state of mind your objective should be to concentrate on learning and experimentation. You should play to win, and take matches seriously, but not be afraid to try different strategies for the purpose of learning. In this state you aim to maximize your learning, not your win-percentage. Feel free to think about your moves, what would have happened if you took another route, what you are going to try in the next matchup and so on. It is only beneficial to...

 Summary of Human Evolution

ABOUT 13.5 BILLION YEARS AGO, MATTER, energy, time and space came into being in what is known as the Big Bang. The story of these fundamental features of our universe is called physics. About 300,000 years after their appearance, matter and energy started to coalesce into complex structures, called atoms, which then combined into molecules. The story of atoms, molecules and their interactions is called chemistry. About 3.8 billion years ago, on a planet called Earth, certain molecules combi...

 Anger isn't Necessary and Gets In the Way

A prominent author who recently disagreed with me on a technical matter quickly labelled me as belonging to a ‘department of bullshit’. Ouch! How is it possible not to get offended by this sort of thing, especially when it’s coming not from an anonymous troll, but from a famous guy with more than 200,000 followers? By implementing the advice of another Stoic philosopher, the second-century slave-turned-teacher Epictetus, who admonished his students in this way: ‘Remember that it is we...

 Example of Lexical Context

A duct-less split can produce the exact amount of energy needed to temper an envelope. When I first read this sentence, my mind started to try to make connections to envelopes and wondered if tempering had something to do with getting or keeping the glue on the flap. If you are an engineer, you probably know that the sentence above refers to equipment and its capability of cooling a room. As with any topic, the more you know about heating and cooling, the easier it is to learn and understa...

 Sugar Impacts Learning

The DHA-deprived rats also developed signs of resistance to insulin, a hormone that controls blood sugar and regulates synaptic function in the brain. A closer look at the rats' brain tissue suggested that insulin had lost much of its power to influence the brain cells. "Because insulin can penetrate the blood–brain barrier, the hormone may signal neurons to trigger reactions that disrupt learning and cause memory loss," Gomez-Pinilla said. He suspects that fructose is the culprit behi...

 We are the Dreams of a Future AI

An evolving cyberspace becomes effectively ever more capacious and long lasting, and so can support ever more minds of ever greater power. If these minds spend only an infinitesimal fraction of their energy contemplating the human past, their sheer power should ensure that eventually our entire history is replayed many times in many places, and in many variations. The very moment we are now experiencing may actually be (almost certainly is) such a distributed mental event, and most likely is ...

 Utopia

One may picture, then, these beings, nuclearly resident, so to speak, in a relatively small set of mental units, each utilizing the bare minimum of energy, connected together by a complex of etherial intercommunication, and spreading themselves over immense areas and periods of time by means of inert sense organs which, like the field of their active operations, would be, in general, at a great distance from themselves. As the scene of life would be more the cold emptiness of space than the w...

 Plank's Constant

In the year 1900 Max Planck wrote down an equation, E = hv, where E is the energy of a light wave, v is its frequency, and h is a constant which we now call Planck's constant. Planck's equation was the beginning of quantum theory. It said that energy and {22} frequency are the same thing measured in different units. Energy is measured in ergs and frequency in cycles. Planck's constant gives you the rate of exchange for converting frequency into energy, namely, 6 × 10–27 ergs per cycle. B...
