Awesome pictures from around the world | Vivi The Mage Someone sent me these in a chain email, it was horribly formatted. I also do not know who made the comments, or how accurate they are. I take zero credit in the pictures, I just wanted to compile them nicely for all to see. The world’s highest chained carousel, located in Vienna, the height of 117 meters.

Fibonacci Number The Fibonacci numbers are the sequence of numbers defined by the linear recurrence equation with . The Fibonacci numbers for , 2, ... are 1, 1, 2, 3, 5, 8, 13, 21, ... Fibonacci numbers can be viewed as a particular case of the Fibonacci polynomials Fibonacci numbers are implemented in the Wolfram Language as Fibonacci[n]. The Fibonacci numbers are also a Lucas sequence , and are companions to the Lucas numbers (which satisfy the same recurrence equation). The above cartoon (Amend 2005) shows an unconventional sports application of the Fibonacci numbers (left two panels). A scrambled version 13, 3, 2, 21, 1, 1, 8, 5 (OEIS A117540) of the first eight Fibonacci numbers appear as one of the clues left by murdered museum curator Jacque Saunière in D. The plot above shows the first 511 terms of the Fibonacci sequence represented in binary, revealing an interesting pattern of hollow and filled triangles (Pegg 2003). ends in zeros. The Fibonacci numbers give the number of pairs of rabbits is given by .
Why Nikola Tesla was the greatest geek who ever lived Additional notes from the author: If you want to learn more about Tesla, I highly recommend reading Tesla: Man Out of Time Also, this Badass of the week by Ben Thompson is what originally inspired me to write a comic about Tesla. Ben's also got a book out which is packed full of awesome. There's an old movie from the 80s on Netflix Instant Queue right now about Tesla: The Secret of Nikola Tesla. It's corny and full of bad acting, but it paints a fairly accurate depiction of his life. The drunk history of Tesla is quite awesome, too. History.com has a great article about Edison and how his douchebaggery had a chokehold on American cinema.
100 Incredible Open Lectures for Math Geeks While many math geeks out there may have been teased for their love of numbers, it’s math that makes the world go round, defining everything from the economy to how the universe itself operates.

Moving slabs [This Dynamic Earth, USGS] The layer of the Earth we live on is broken into a dozen or so rigid slabs (called tectonic plates by geologists) that are moving relative to one another. "Historical perspective" Mysterious number 6174 March 2006 Anyone can uncover the mystery The number 6174 is a really mysterious number. At first glance, it might not seem so obvious. But as we are about to see, anyone who can subtract can uncover the mystery that makes 6174 so special. Kaprekar's operation In 1949 the mathematician D. It is a simple operation, but Kaprekar discovered it led to a surprising result. When we reach 6174 the operation repeats itself, returning 6174 every time. We reached 6174 again! A very mysterious number... When we started with 2005 the process reached 6174 in seven steps, and for 1789 in three steps. Only 6174? The digits of any four digit number can be arranged into a maximum number by putting the digits in descending order, and a minimum number by putting them in ascending order. 9 ≥ a ≥ b ≥ c ≥ d ≥ 0 and a, b, c, d are not all the same digit, the maximum number is abcd and the minimum is dcba. which gives the relations for those numbers where a>b>c>d. For three digit numbers the same phenomenon occurs. and
Some Bizzare and Odd things around us… Beauty of the nature lies in viewer’s eyes. A photograph is just a way to show or represent that beauty. Here is a bunch of some wonderful pictures which are not only the example of beautiful photography but are also a photograph of some miracles happening in the world. You can also call it the creativity and innovation of photographer’s mind. I think it was at the peak while taking these pictures. Some photographs are just the example of wonder created by God. Some are really very cute and heart touching. I am simply in love with these photographs and I am sure you will too. Gibraltar Airport is one of the most extraordinary airports around the world.

Nick's Mathematical Puzzles Welcome to my selection of mathematical puzzles. What's new? See puzzle 160. The math puzzles presented here are selected for the deceptive simplicity of their statement, or the elegance of their solution. They range over geometry, probability, number theory, algebra, calculus, trigonometry, and logic. Explaining how an answer is arrived at is more important than the answer itself. Each puzzle is assigned a level of difficulty of between one and four stars, with four being the most difficult. The source for each problem is given at the bottom of the solution page. I welcome feedback of any kind. Some brief biographical information. Nick Back to top
BrowserQuest Mystery as spiral blue light display hovers above Norway By Mail Foreign Service Updated: 15:15 GMT, 10 December 2009 What's blue and white, squiggly and suddenly appears in the sky? If you know the answer, pop it on a postcard and send it to the people of Norway, where this mysterious light display baffled residents yesterday. Speculation was increasing today that the display was the result of an embarrassing failed test launch of a jinxed new Russian missile. The Bulava missile was test-fired from the Dmitry Donskoi submarine in the White Sea early on Wednesday but failed at the third stage, say newspapers in Moscow today. Strange spiral: Residents in northern Norway were left stunned after the lightshow, which almost looked computer-generated, appeared in the skies above them [caption] This emerged despite earlier reports denying a missile launch yesterday. The light appears to be unconnected with the aurora borealis, or northern lights, the natural magnetic phenomena that can often be viewed in that part of the world. What could it be?

Demon core Subcritical mass of plutonium used in the Manhattan Project Manufacturing and early history The next bomb of the implosion type had been scheduled to be ready for delivery on the target on the first good weather after August 24th, 1945. Marshall added an annotation, "It is not to be released on Japan without express authority from the President", as President Harry S. First incident On August 21, 1945, the plutonium core produced a burst of neutron radiation that led to physicist Harry Daghlian's death. Second incident A re-creation of the 1946 experiment. Under Slotin's own unapproved protocol, the shims were not used and the only thing preventing the closure was the blade of a standard flat-tipped screwdriver manipulated in Slotin's other hand. The nearest person to Slotin, Graves, who was watching over Slotin's shoulder and was thus partially shielded by him, received a high but non-lethal radiation dose. Medical studies Planned uses and fate of the core
