It's time for 3-D


Watch out........3-D is coming with bare eyes.You can enjoy the game in 3-D without wearing clunky, chunky 3-D eyeglasses.And this is done by Nintendo and Toshiba.New glasses-free 3-D devices are about to hit the market, and their backers are hoping they'll make 3-D spectacles as obsolete as Smell-O-Vision. These gadgets, described as "autostereo" to distinguish them from the kind requiring eyewear, will include not only game consoles but also cameras, cellphones, and tablet computers. Among the first will be autostereo 3-D TVs, just now hitting stores in Japan, and Nintendo's 3-Ds game consoles, due for release worldwide early next year.

There’s lots of reasons to carry on using a Firefox’s great web browser, the most visually noticeable change to Firefox with the new release is the introduction of a new feature called Personas. You can download this from www.getpersonas.com, you can choose from other 35,000 themes on offer that let you customize the way that Firefox looks.

When viewing Personas, you can hover over one to see how it will look in your browser, where you’ll get a preview before you choose to install it by clicking it. Downloaded themes can be managed via the Add-Ons window, where you can change and uninstall your Personas using the “Themes” tab.

History of Fibonacci series

The "greatest European mathematician of the middle ages", his full name was Leonardo of Pisa, or Leonardo Pisano in Italian since he was born in Pisa,Italy (see Pisa on Google Earth), the city with the famous Leaning Tower, about 1175 AD. Pisa was an important commercial town in its day and had links with many Mediterranean ports. Leonardo's father, Guglielmo Bonacci, was a kind of customs officer in the present-day Algerian town of Béjaïa, (see Bejaia on Google Earth ) formerly known as Bugia or Bougie, where wax candles were exported to France. They are still called "bougies" in French.
So Leonardo grew up with a North African education under the Moors and later travelled extensively around the Mediterranean coast. He would have met with many merchants and learned of their systems of doing arithmetic. He soon realised the many advantages of the "Hindu-Arabic" system over all the others.
D E Smith points out that another famous Italian - St Francis of Assisi (a nearby Italian town) - was also alive at the same time as Fibonacci: St Francis was born about 1182 (after Fibonacci's around 1175) and died in 1226 (before Fibonacci's death commonly assumed to be around 1250).
By the way, don't confuse Leonardo of Pisa with Leonardo da Vinci! Vinci was just a few miles from Pisa on the way to Florence, but Leonardo da Vinci was born in Vinci in 1452, about 200 years after the death of Leonardo of Pisa (Fibonacci).

  • The Fibonacci Numbers

 In Fibonacci's Liber Abaci book, chapter 12, he introduces the following problem (here in Sigler's translation - see below):

How Many Pairs of Rabbits Are Created by One Pair in One Year
A certain man had one pair of rabbits together in a certain enclosed place, and one wishes to know how many are created from the pair in one year when it is the nature of them in a single month to bear another pair, and in the second month those born to bear also.
He then goes on to solve and explain the solution:
Because the above written pair in the first month bore, you will double it; there will be two pairs in one month.
One of these, namely the first, bears in the second montth, and thus there are in the second month 3 pairs;
of these in one month two are pregnant and in the third month 2 pairs of rabbits are born, and thus there are 5 pairs in the month;
...
there will be 144 pairs in this [the tenth] month;
to these are added again the 89 pairs that are born in the eleventh month; there will be 233 pairs in this month.
To these are still added the 144 pairs that are born in the last month; there will be 377 pairs, and this many pairs are produced from the abovewritten pair in the mentioned place at the end of the one year.
You can indeed see in the margin how we operated, namely that we added the first number to the second, namely the 1 to the 2, and the second to the third, and the third to the fourth and the fourth to the fifth, and thus one after another until we added the tenth to the eleventh, namely the 144 to the 233, and we had the abovewritten sum of rabbits, namely 377, and thus you can in order find it for an unending number of months.
                                                                                                                              beginning 1
                                                                                                                                       first 2
                                                                                                                                   second 3
                                                                                                                                      third 5
                                                                                                                                    fourth 8
                                                                                                                                      fifth 13
                                                                                                                                     sixth 21
                                                                                                                                 seventh 34
                                                                                                                                   eighth 55
                                                                                                                                     ninth 89
                                                                                                                                   tenth 144
                                                                                                                              eleventh 233
                                                                                                                                      end 377
  • The Fibonacci numbers are Nature's numbering system. They appear everywhere in Nature, from the leaf arrangement in plants, to the pattern of the florets of a flower, the bracts of a pinecone, or the scales of a pineapple. The Fibonacci numbers are therefore applicable to the growth of every living thing, including a single cell, a grain of wheat, a hive of bees, and even all of mankind.

                                       e.g. 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, etc.

 These numbers possess a number of interrelationships, such as the fact that any given number is     approximately 1.618 times the preceding number.

The first two numbers in the series are one and one. To obtain each number of the series, you simply add the two numbers that came before it. In other words, each number of the series is the sum of the two numbers preceding it.
Note: Historically, some mathematicians have considered zero to be a Fibonacci number, placing it before the first 1 in the series. It is known as the zeroth Fibonacci number, and has no real practical merit. We will not consider zero to be a Fibonacci number in our discussion of the series.
Binet's Formula [GO to 'Binet's Formula In Action']
The Fibonacci series is defined recursively. That is, in order to find each term of the series using the definition, you have to find all the terms that precede it. This makes finding the nth term very difficult for large values of n, as you must find every term that comes before.
However, there could be a way to find Fibonacci numbers without using the definition. If this were possible, one would be able to find the nth term of the series simply by plugging n into a mathematical formula.
In 1843, Jacques Philippe Marie Binet discovered just such a formula for finding the nth term of the Fibonacci series. The formula itself looks like this:

The proof of this equation is dependant on concepts we have not yet explored, and will be given in full in a later lesson.
Binet's formula involves two very special numbers, the two numerical expressions within the lowest sets of parentheses. Remember these two numbers: they will become very important in later sections.
