Randomness is the lack of pattern or predictability in events. A random sequence of events, symbols or steps has no order and does not follow an intelligible pattern or combination. Individual random events are by definition unpredictable, but in many cases the frequency of different outcomes over a large number of events (or "trials") is predictable. For example, when throwing two dice, the outcome of any particular roll is unpredictable, but a sum of 7 will occur twice as often as 4. In this view, randomness is a measure of uncertainty of an outcome, rather than haphazardness, and applies to concepts of chance, probability, and information entropy.
The fields of mathematics, probability, and statistics use formal definitions of randomness. In statistics, a random variable is an assignment of a numerical value to each possible outcome of an event space. This association facilitates the identification and the calculation of probabilities of the events. Random variables can appear in random sequences. A random process is a sequence of random variables whose outcomes do not follow a deterministic pattern, but follow an evolution described by probability distributions. These and other constructs are extremely useful in probability theory and the various applications of randomness.
A pulse wave or pulse train is a kind of non-sinusoidal waveform that is similar to a square wave, but does not have the symmetrical shape associated with a perfect square wave. It is a term common to synthesizer programming, and is a typical waveform available on many synthesizers. The exact shape of the wave is determined by the duty cycle of the oscillator. In many synthesizers, the duty cycle can be modulated (sometimes called pulse-width modulation) for a more dynamic timbre. The pulse wave is also known as the rectangular wave, the periodic version of the rectangular function.
The Fourier series expansion for a rectangular pulse wave with period T and pulse time τ is
Note that, for symmetry, the starting time (t = 0) in this expansion is halfway through the first pulse. The phase can be offset to match the accompanying graph by replacing t with t - τ/2.
A pulse wave can be created by subtracting a sawtooth wave from a phase-shifted version of itself. If the sawtooth waves are bandlimited, the resulting pulse wave is bandlimited, too. Another way to create one is with a single ramp wave (sawtooth or triangle) and a comparator, with the ramp wave on one input, and a variable DC threshold on the other. The result will be a precisely controlled pulse width, but it will not be bandlimited.
A finger is a limb of the human body and a type of digit, an organ of manipulation and sensation found in the hands of humans and other primates. Normally humans have five digits, the bones of which are termed phalanges, on each hand, although some people have more or fewer than five due to congenital disorders such as polydactyly or oligodactyly, or accidental or medical amputations. The first digit is the thumb, followed by index finger, middle finger, ring finger, and little finger or pinky. According to different definitions, the thumb can be called a finger, or not.
The thumb (connected to the trapezium) is located on one of the sides, parallel to the arm.
The palm has five bones known as metacarpal bones, one to each of the 5 digits. Human hands contain fourteen digital bones, also called phalanges, or phalanx bones: two in the thumb (the thumb has no middle phalanx) and three in each of the four fingers. These are the distal phalanx, carrying the nail, the middle phalanx, and the proximal phalanx.
Watch Part 2 here: http://www.youtube.com/watch?v=oVnqruB387M One week ago I've had a piercer implant a magnet into the tip of my left ring finger opposite the thumb. Once my finger regains feeling I will be able to sense otherwise invisible electromagnetic alternating fields like those coming from electric fans, live wires, microwave ovens, shop security systems, phones, power bricks, and countless other things. My reason for getting the implant was to satisfy my curiosity regarding this sixth sense. It also makes for great bar tricks. This video demonstrates the strength of the magnet and shows how well it has healed within 6-7 days. The lump you can see in my finger is largely due to swelling and will eventually disappear. The small scab you see is where the large needle (and later th...
Me, Xi Jin, Danny Hynam, Alex Boffey and Harry Yeates road-tripped down to Bristol to go to Crossed Fingers 2! All of us and Ross (from Blosom) crashed at Kerry's, and hung out and had a totally rad time fingerboarding and skating all weekend! Xi placed fifth, I placed fourth, Harry placed third and Boffey placed second! Northern domination! Thanks to Kerry for putting us up and hosting the event! And cheers to Xi and Boffey for driving us! This is what fingerboarding is all about. Songs - Red Leather by Peach Kelli Pop Hey Dickhead by The Maine Coons

When the neon lights shine down,
and there's no one else around,
whatcha gonna do when the clock strikes two,
and all the freaks come out,
On the ave....
When the neon lights shine down,
and there's no one else around,
whatcha gonna do when the clock strikes two,
and all the freaks come out,
On the ave....
When you're on the ave...
Now I got a reason for breathin,
goodbye Hollywood and hello Cleveland.
I didn't tell my girl I was leavin,
packed my bags, jumped in the Lincoln.
Suicide doors more to the meaning,
Four on the floor, three on the tree and,
I'm doin' speed on the 405 freeway,
Officer give a white boy some leeway.
Downtown with the he-say she-say,
Dont mean nothin cause the he-she's cliche.
Downtown where your dreams just decay,
$40 for a ? $20 for a BJ
But uptown they play my CD's
Girls wanna fuck me, boys wanna be me.
Who's Mickey, she said, and smiled in a special way.
When the neon lights shine down,
and there's no one else around,
whatcha gonna do when the clock strikes two,
and all the freaks come out,
On the ave....
When you're on the ave...
Now I'm gonna keep on creepin'
Latchkey kids gettin' high all weekend.
Lookin past the hood of my Fleetwood,
Jesus on the dash and the king on the speaker.
You can find me in the back of the theater like
Pee Wee Herman, holdin my weiner.
I ain't seen her since the milk went bad
and I didn't mean to beat her is what I told her dad..
Round town it's a stone cold fact,
Avalon got a gun in his lap.
Round town you can hear the clap,
when I take the stage, and shake my ass.
Out of town you can feel the heat,
when my bus pulls up and steals your freaks.
Out of town you can feel the noise,
come on girls, rock your boys!
When the neon lights shine down,
and there's no one else around,
whatcha gonna do when the clock strikes two,
and all the freaks come out,
On the ave...
When you're on the ave...
When the neon lights shine down,
and there's no one else around,
whatcha gonna do when the clock strikes two,
and all the freaks come out,
On the ave....
When you're on the ave...
Now I'm gonna speak on freedom,
do what you like fuck other people.
They tell you what you're supposed to do,
how about your girl do me, and you do you.
Now kick rocks before you get shot,
in the back of the head all you heard was POP
Goes to weasel cause the weasel smoke rock,
Hypodermic needle paramedic on the block.
Chop your body up, drop it off the dock,
why you gotta go and call the mothafuckin cops?
It's too late babe it could've been great,
but you had to go and stab me in the back with a steak knife.
Late night, waste away,
Chain smokin' til the drapes turn grey.
Cocaine helps me face the day,
and then the pills wash the pain away.
I won't be blamed for your mistakes,
burned at the stake,
for God's sake.
When the neon lights shine down,
and there's no one else around,
whatcha gonna do when the clock strikes two,
and all the freaks come out,
On the ave....
When you're on the ave...
When the neon lights shine down,
and there's no one else around,
whatcha gonna do when the clock strikes two,
and all the freaks come out,
On the ave....
