The partition of a number is the number of distinct ways in which positive whole numbers can be added together to give the number. Starting with one, we can place the numbers in ascending order on a grid and show the distinct solutions. You will see that the solutions for two includes the solution for one, but with one extra combination. Similarly, the solutions for three, include the solutions for two and one, only with extra combinations. This pattern continues for all Partition Numbers and we can think of the sequence for Partitions as an accumulative sequence, which builds on the previous solutions.
You may also notice that the additional solutions for each number do not involve combinations which include one. So for example, the additional number of solutions for the number five is two more than the number of solutions for four, but none of these additional solutions include one in the combination (2+3 and 5). We can also reverse this argument and say that solutions for five which include one are the same as the solutions for four.
Looking at solutions which don’t include one can be a helpful way of reducing the number of combinations and focusing our attention on just the additional solutions. We will look at both ways in more detail next.
Prime Numbers upto 100 Euclid around 300 BC stated that Prime numbers are more than any assigned quantity of prime numbers.According to Euclid there are infinite prime numbers.Prime numbers are like siblings, although members of the same big family resembling each other, but not quite alike.Which is the oddest of all prime numbers? It is 2 mainly because it is the only even prime number.The number 1 has only one positive divisor and that is one itself.Every number (a), where a>1, would have at least two positive divisors, ‘1’ and ‘a’.A number "a > 1" is called a prime number or we simply call it prime if it has only two positive divisors.
Won this on eBay last weekend and it arrived today.
Its an Electronics & LED wearable maker's dream badge. It features a Matrix of 147 seriously bright surface mounted 0805 red LED's in a 7x21 configuration meaning it can handle the alphabet, numbers and most used symbols. It is easily programmed using a simple set of buttons on the rear. It can hold up to 50 characters and can run at 4 speeds. It uses a single CR2032 battery which is claimed to provide 6 hours of continuous use.
Its a pretty cool and handy little gadget that's ideal if you need a message to be seen repeated or if you just want to program it and use the built in high power magnet and bar on the back that will pretty much keep it in place through any clothing and it is a seriously powerful magnet.
I found it on eBay purely by chance as it came up as a recommended auction while I was hunting down some vintage LED 7 digit display units. I clicked on it and it had just over 30 mins to go with no bids and a starting point of £4.99. Needless to say I slapped a max of about £10 on it then went off and did something else and forgot to check back till next day when I saw that I had got it on its first and only bid. Grand total of £7.99 inc postage. BARGAIN!
Its pretty fun, I live on a 90 degree corner of a road where a 2nd road joins it too and being 100m from the City Centre I get alot of traffic, pedestrians and drunkards (I also live directly next door to a pub) so I could put anything (non-offensive) on it and leave it scrolling.
The inner hacker in me is telling me to unscrew the 5 cross head screws, take a look and see what is running it and decide if it's hackable from the programming point of view and also hardware as I want to rig up my pair of 180x80mm solar panels and handy Arduino Solar power Shield with a small Li-ion 3.7v battery so it trickle charges through the day while getting its power from the day light and then automatically it will go to battery power once the solar panels drop to a certain low output. Should be an easy and removable mod just to take the regulated 3v3 line from the attached duino figure the required power and add resistor then just feed in the 2 wires onto the input voltage and the ground points. Maybe even add one of my little 200m Adafruit RF receiver 4 way switches and 4 button key fob to turn it on and off for a start, if possible then hack the circuit to replace the speed select switch with one of the other 3 lines from the RF gear. It would be piece of cake to print a new case for it to hold any extra gear.
I think this thing was Insane value for £8, I haven't a clue who makes or sells them. It was all packaged still, but looks like it's been sat around for a few years. You couldn't build this yourself for the price paid and it would be a pain in the arse to solder 147x 0805 size LED's along with a ton of resistors, caps and then the MCU and most likely a handful of shift registers all in SMD configuration. When I have more time, I will open it up and see whats visible, and as long as the IC's are not encased in that horrible black resin then I can see if the MCU is marked and maybe even get a chance to breakout my Bus Pirate to investigate which I have only needed for and used about 5 times in the past 9 months. It would be awesome if its an Atmel chip in there as then hacking the code becomes simples!
I will keep this updated and post when I open her up (which I already know I am going to end up doing at some point anyway)
Anyway I think it was a great buy and find it hard to think that it or a similar item could be got for that price. A great find.
these numbers are going to take a while...I think I will machine stitch the pockets on instead of blanket stitching them...
I was trying to get a negative effect with this picture of colourful number tiles. I think I got more of a metallic effect. What do you think?
Fifty-five has the interesting property that it is the 10th Fibonacci number and the sum of the numbers 1 to 10.
It is a heptagonal number, a centered nonagonal number, and a triangular number (the sum of the numbers 1 to 10) and a square pyramidal number (the sum of the squares of the integers 1 to 5). It is also a Fibonacci number (the largest Fibonacci number to also be a triangular number) and a Kaprekar number).
55 is a semiprime, being the product of 5 and 11 and it is the 2nd member of the (5.q) semiprime family. 55 is one of only two integers with an aliquot sum of 17 (the other being 39). 55 has an aliquot sequence of 4 members: (55, 17, 1, 0).
Fifty-five is also:
* The number of Delegates who attended the United States Constitutional Convention in 1787
* In US gallons, a common size of drum containing liquids; see 55 US gallon drum
* In miles per hour,
o the highest speed limit allowed in the United States between 1974 and 1986 per the National Maximum Speed Law
o In many states of the United States, a very common speed limit for rural secondary roads and many urban freeways.
* In years of marriage, the emerald wedding anniversary
* The code for international direct dial phone calls to Brazil
* The number of European route E55 from Helsingborg, Sweden to Greece
* The designation of I-55, a freeway that runs from Louisiana to Illinois

Unable so lost,
I can't find my way,
Been searching, but I have never seen,
A turning, a turning from deceit.

Went down to Nolin lake last weekend with my brother-in-law and our two friends Keith and Brandon. I just bought a Rokinon (Samyang, Bower, whatever) 35mm 1.4 and this was the perfect weekend to play with it!
Loved the light here, so I snapped a quick one of this sign thing that I'm sure is important.
