Hacking Knowledge: 77 Ways to Learn Faster, Deeper, and Better If someone granted you one wish, what do you imagine you would want out of life that you haven’t gotten yet? For many people, it would be self-improvement and knowledge. Newcounter knowledge is the backbone of society’s progress. Great thinkers such as Leonardo da Vinci, Thomas Edison, Benjamin Franklin, Albert Einstein, and others’ quests for knowledge have led society to many of the marvels we enjoy today. Your quest for knowledge doesn’t have to be as Earth-changing as Einstein’s, but it can be an important part of your life, leading to a new job, better pay, a new hobby, or simply knowledge for knowledge’s sake — whatever is important to you as an end goal.
10 More Mysterious Conspiracy Theories Mysteries To date we have around seven conspiracy theory lists or lists containing entries related to such. This new list is a welcome addition as it has been some time since our last one and they are always extremely fascinating topics to read about. The world is full of conspiracy theories – many of which contain elements of mystery. This will definitely not be the last list of this type. Theories surrounding the Ararat Anomaly arose from a single black and white photograph taken in 1949 by a USAF recon plane performing routine intelligence gathering of the Ararat massif, which was in an area of military interest at the time.
Heron's fountain Heron's fountain is a hydraulic machine invented by the 1st century AD inventor, mathematician, and physicist Heron, also known as Hero of Alexandria. Heron studied the pressure of air and steam, described the first steam engine, and built toys that would spurt water, one of them known as Heron's fountain. Various versions of Heron's fountain are used today in physics classes as a demonstration of principles of hydraulics and pneumatics. Construction[edit] 93 Random Facts about Rome With nearly 3,000 years of rich history, Rome is often called the “Eternal City.” Though Rome dates back to possibly 625 B.C., the oldest continuously populated city in the world is widely to be considered Byblos in present-day Lebanon dating back to 5000 B.C.j Some linguistic possibilities for the origin of the word “Rome” include the Etruscan word rhome meaning “strength” or “river.” It may also be related to the root rum meaning “teat,” referring to the wolf that suckled the twins Romulus and Remus. Another theory is that Roma was the daughter of Aeneas, a mythical founder of Rome.j Because there were apparently few women in early Rome, Romulus (c. 771-717 B.C.) kidnapped neighboring Sabine women. -- Posted March 7, 2009
The 13 Most Important Numbers in the Universe - James D. Stein's Cosmic Numbers In the 17th century, scientists understood three phases of matter—solids, liquids and gases (the discovery of plasma, the fourth phase of matter, lay centuries in the future). Back then, solids and liquids were much harder to work with than gases because changes in solids and liquids were difficult to measure with the equipment of the time. So many experimentalists played around with gases to try to deduce fundamental physical laws. Robert Boyle was perhaps the first great experimentalist, and was responsible for what we now consider to be the essence of experimentation: vary one or more parameter, and see how other parameters change in response. It may seem obvious in retrospect, but hindsight, as the physicist Leo Szilard once remarked, is notably more accurate than foresight.
Elysium Elysium or the Elysian Fields (Ancient Greek: Ἠλύσιον πεδίον, Ēlýsion pedíon) is a conception of the afterlife that developed over time and was maintained by certain Greek religious and philosophical sects and cults. Initially separate from the realm of Hades, admission was reserved for mortals related to the gods and other heroes. Later, it expanded to include those chosen by the gods, the righteous, and the heroic, where they would remain after death, to live a blessed and happy life, and indulging in whatever employment they had enjoyed in life.[1][2][3][4][5][6] The ruler of Elysium varies from author to author: Pindar and Hesiod name Cronus as the ruler,[9] while the poet Homer in the Odyssey describes fair-haired Rhadamanthus dwelling there.[6][7][10][11]

Kill Your Darlings There is nothing like the moment when you suddenly come upon the answer to a design problem. Whether it is a particular interaction or the perfect design element, it is a moment of pure elation. However, in that moment, there is a always a risk of an emotional attachment being formed. Essentially, we have the potential to surrender our ability to see beyond the “perfect solution” we have just created. Arthur Quiller-Couch, a British journalist, critic, and novelist once said,"Murder your darlings." While this quote was aimed at aspiring writers, I believe that it is equally relevant to designers.
Gladiators, 50 AD Gladiators, 50 AD The spectacle of gladiatorial combat was initiated by wealthy Romans over 250 years before the birth of Christ as a part of the ceremonies held to honor their deceased relatives. Later, these games became separate events sponsored by Rome's leading citizens in order to enhance their prestige. With the decline of the republic and the rise of the empire, gladiator games were appropriated by the emperor. The primary purpose of these life-or-death duels was to entertain the multitude of spectators that jammed the arena. free university lectures - computer science, mathematics, physics, chemistry Whether your goal is to earn a promotion, graduate at the top of your class, or just accelerate your life, lectures can help get you there.

Life's Biggest Challenges In my over thirty years in clinical practice, I have run into many challenging problems and issues. These challenges included severe treatment-resistant depression, debilitating obsessive compulsive disorder, and extreme cases of borderline personality disorder among many others. In the vast majority of cases, most clients eventually manage to get much better. But the most vexing issue I have ever dealt with did not involve a diagnosis at all–in the usual sense.
