In which business book was the Hedgehog Concept introduced?

Answer
The book is called Good to Great: Why Some Companies Make the Leap… and Others Don’t

It is written by Jim Collins

Collins calls the Hedgehog Concept, a product or service that leads a company to outshine all worldwide competitors, that drives a company’s economic engine and that a company is passionate about.

Writers, let me ask you some nonsense… And how do you choose a POV?

Actually, I have more than 1 questions aside from the nonsenses…
I’m the type of person that thinks too much(most of on nonsenses…) and my original ideals gets twisted into something that made absolutely no sense at all… xD
Heahhh… I don’t really know how to put this. *scribbles*

All questions plus the nonsense are down below. =3=

Ok. So, the main location of my story is a universe exists based on the law of Reason, the exists because (?). 7 people in my story held a special mirror that’s supposed to be link to the other universe known as parallel world’. Yup, to keep it short, they’re born cursed and that cursed keep them from aging(meaning they can be killed, die of illness, poisoned to death except death by old age.) but it does weaken their body at some point.

But there are a total of 8 mirrors, the last one is located in the core of their planet; the Abyss. And the (gate/portal/door

Answer
I think you should call them Malte (Mal is from Maledetto (cursed) and te from gente (people))

and i guess since there world is the law of reason and it’s a parallel world you could do the opposite of reason for our world.

if you want to change POV each chapter you could name each chapter after whoever is narrating the story. it’s usually better to just stick to one persons pov, or you could do 3rd person.

i don’t think readers will think to much about Xaviers age, i mean when people read vampire stories they don’t worry about the age soooo.

1) Girl, Redish brown hair, brown eyes, tall, fit.
2) umm, i’m not sure, i guess something different every time.
3) something with eggs, and green onions lol.
4) yes, and i’d probably have to do it in secret. having it fallow me around would be pretty cool though.
5) hah, that would awesome! i’d probably have to figure out how the hell it got up to the area i live, very far away from any were with lions, and freezing.
6) i usually write alone, so i guess the pet would be further.
7) no, lol, i have nothing to do today lol 4, i’m right aren’t I?!?!?! that’s okay, i know i am.
9) depends on how i feel about him, his personality.
10) Sidra, lol, i just made it up, nothing came to my mind after reading that sentence

Question about sound waves?

“Every year, 100 000 hedgehogs are killed by vehicles on British roads. It has been suggested that if a whistle emitting a sound wave of 5000Hz is attached to the front of a car bumper, that when the hedgehog hears the whistle it will remain at the side of the road.

“The movement of the car forces air into the whistle and creates the sound.

“State and explain what happens to the sound emitted by the whistle as the car moves faster. How may this change be to the hedgehog’s advantage?”

So we’re obviously talking about pitch and loudness of the sound here, meaning frequency and amplitude, respectively.

Can we use v = fλ? What /exactly/ is the relationship between velocity, speed, and wavelength of a wave? As f increases, λ decreases, right? But how does v play into this? And does this only apply for electromagnetic waves, or can it work for sound and water waves, as well?
Thanks. I need to clear up on my relationship concepts.

Answer
You should read the Wikipedia article about the Doppler effect. The article describes in good detail what happens if the observer or the sound source are moving.

In classical physics, which deal with wave propagation in a medium like air the general equation is:

f = (v+v_r)/(v + v_s) * f_0, with

f_0= emitted frequency, f=received frequency, v=wave velocity in air, v_r=receiver velocity relative to air, v_s= source velocity relative to air. If both r and s approach each other f rises.

the receiver (hedgehog) velocity is negligible compared to either the car or the wave velocity, so you can assume it’s zero.

thus you can reduce the equation to:

f = (v)/(v + v_s) * f_0

Beware that this formula is only valid if source and receiver are approaching each other directly.

In Astronomy the doppler effect of electromagnetic waves is also known as red shift or blue shift, which describes the color of stars changing due to the spectral frequency shift towards the long or short wavelength end of the visible spectrum. Blue shift means that a star/light source approaches the observer (or the other way around) and red shift means the light source moves away from the observer (or the observer moves away from the light source). You can use the same formula for calculating red shift or blue shift of electromagnetic waves, if the velocity is much lower than the speed of light. In the case of relativistic velocities you have to use the formulas for relativistic color shifts.

Again, I recommend you read the Wikipedia article. It’s very informative and should be well understandable.

how do you make sonic shoes like sonic the hedgehog shoes please help?

i really need help its for an anime convention and i need help heres a model im using now http://fc05.deviantart.com/fs28/f/2008/091/c/7/Sonic_Human_Concept_by_arvalis.jpg the link should work please i need answers fast please

Answer
EASY!

ok …this will take a little work…

first get a good pair of plain white running shoes that look somewhat like sonic’s then take the laces out spray paint the parts except the bottom red then use like a peice of yellow tape over where the straps should be and be creative for the other details
