Your Math and Physics Questions Answered
Physicist: This famous equation is a little more subtle than it appears. It does provide a relationship between energy and matter, but importantly it does not say that they’re equivalent. First, it’s worth considering what energy actually is. Rather than being an actual “thing” in the universe, energy is best thought of as an abstract (there’s no such thing as pure energy). Energy takes a heck of a lot of forms: kinetic, chemical, electrical, heat, mechanical, light, sound, nuclear, etc. Each different form has it’s own equation(s).

Are You Prepared? by Kevin Wilson Index I hope this guide will help you prepare for a range of different emergency situations. 5 Unexpected Downsides of High Intelligence You know that phrase, "Ignorance is bliss"? There's a reason it's stuck around all these years. Because having the upper hand in intelligence might give you an advantage in some areas, like crossword puzzle solving and quantum physics-ing, but it also might just screw up your life forever. 12 Absolutely and Insanely Essential Utilities For Programmers In every era in recent times there has been one profession that for a short while you could enter without formal training. Autodidacts in the 19th century could read the law without recourse to formal education (see Abe Lincoln). In the early 20th century it was aviation. For a short while in the 1980s and early 1990s, it was computing, thanks to the release of the Apple IIe, the IBM PC and the Mac. Were it not for that Window® of opportunity, I hate to think what would have become of me. (Hey buddy, can you spare a dime?)

Hammack Home This book is an introduction to the standard methods of proving mathematical theorems. It has been approved by the American Institute of Mathematics' Open Textbook Initiative. Also see the Mathematical Association of America Math DL review (of the 1st edition), and the Amazon reviews. The second edition is identical to the first edition, except some mistakes have been corrected, new exercises have been added, and Chapter 13 has been extended.

Snobbish photons forced to pair up and get heavy Ordinarily, photons—particles of light—don't interact with each other. They interfere, but that's a characteristic that doesn't alter their wavelength or cause them to attract or repel. However, if photons can be induced to interact, it could open up a wide number of applications in quantum computing and optical materials. This sort of radical change can't happen under ordinary circumstances but is possible in special environments. Researchers fabricated just such a medium and produced photons that simultaneously act as though they are massive and mutually attractive. How to Create a Personal Information Encryption Scheme to Easily Hide Your Data in Plain Sight I think the article is saying you could use LastPass to generate your LastPass password and the article's encryption scheme to keep the password in plain sight. Then you would not have to remember it. For example if your LastPass encryption key password was something like /%/K\G,_sO¦R¥ÅÀbݾöà~¼ÐÂ4×òO?

5 Ancient Acts of War That Changed the Face of the Earth Nothing motivates people like war. That's how the Great Wall of China got built--they were protecting themselves against enemies who lived to the north. But that wall is hardly the only time we've changed the face of the planet in the name of winning a war. Some of the ass kickings unleashed with ancient empires on the line were so mind-boggling, the Earth still hasn't recovered. #5. Alexander the Great Turns an Island Into a Peninsula

Meet the 12 year old with an IQ higher than Stephen Hawking’s - TNW Shareables As a three year old with a passion for stars he went on a tour of the Holcomb Observatory and Planetarium at Butler University in Indianapolis. This is the day his mother Kristin Barnett would never forget (via the IndyStar): “We were in the crowd, just sitting, listening to this guy ask the crowd if anyone knew why the moons going around Mars were potato-shaped and not round.Jacob raised his hand and said, ‘Excuse me, but what are the sizes of the moons around Mars?’ ”The lecturer answered, and Jacob looked at him and said the “gravity of the planet . . . is so large that (the moon’s) gravity would not be able to pull it into a round shape.”Silence.

Tying Light in Knots [Slide Show] Knots can help unravel some knotty (sorry!) situations. The mathematical study of knotted shapes has proved constructive for many branches of physics, from understanding how fluids flow to developing quantum computers. Now physicists have found that light itself can be knotted by discovering a new set of solutions to the famous Maxwell equations of electromagnetism.
