What is a Dogman?

The states which border the great Lake Michigan, report the highest number of sightings of

this creature, said to have the head of a canine, and the body of a man, or at least

a body able to walk upright, covered in fur.

It stands seven feet in height, with cold blue eyes, eyes which have also been seen,

glowing amber in the night.

Long before North American lands were settled by Europeans, the Chippewa Indians were familiar

with a creature they called, "the long dog."

Their intimate knowledge of its nature, included a description of its teeth, which they said

were sharp as a knife, as well as the smell of its breath, which was like sulfur, or rotten

eggs.

The Indians believed the long dog was a part of a shapeshifting tribe of skinwalkers, a

menagerie, whose tribal members got stuck, between their animal and human forms.

The first sighting, by people who were not natives, was recorded in the year 1887.

Two lumberjacks, in Wexford County Michigan, observed an animal in the woods which they

thought to be a canine.

Out of their desire to feed the lonely beast, they followed it, deep into the forest.

To escape them, the animal crawled inside a hollow log.

One of the men broke a branch off a nearby tree, thrusting it into the hollow cavity.

From the other end of the log, the creature emerged, screaming in a high-pitched voice

voice, like that of a child.

Then it stood up, on two legs.

It had a man's body, and the head of a hound.

The burly lumberjacks ran away.

In Wisconsin it is known as the Beast of Bray Road.

On this rural road, outside of Elkhorn, in 1936, Mark Schackelman reported a chilling

nocturnal encounter.

As he was driving on a moonless night, he spotted a suspicious figure, which was digging

up an old Indian mound.

He believed it his civic duty to confront the vandal.

As he approached he could see that the creature was covered with hair, and it was standing

erect, at a height of more than six feet.

Its face had a dog muzzle.

Its hands looked deformed, because the thumb was bent at the wrong angle.

Schackelman said, he heard the dogman speak a single word, "gadara", which was barely

more than a growl.

Schackelman backed away, and the beast took flight.

In 2001, in rural Illinois, Shelby Dee was awoken at about four o'clock in the morning,

by the whimpering of his dog.

This made Shelby uneasy.

Looking out the window, he threw on the flood lights that covered his back yard.

Seventy five feet away, he saw a thing like a cross between a man and a dog, standing

upright, and looking straight at him, as he stared back, from his window.

Its shoulders were broad, and well muscled.

The canine head was so massive, that its body leaned forward, in a stooping posture.

For what seemed like an eternity, the Dogman's eyes were locked on Shelby.

Then it turned away, walking into a cornfield.

The corn stalks were at about 8 feet in height at that time of year, and Shelby could still

see the creature's head, as it moved away through the field.

An attack by a Dogman may have been captured by OnStar, in 2006.

A man driving in the township of Troy in Michigan was receiving over OnStar, navigation assistance

from a live operator, when he cried out.

He said he was seeing a very large dog, standing on two legs in the middle of the road.

After swerving to avoid it, he ended up rolling his vehicle.

The whole conversation and the accident was recorded by OnStar, and shortly that recording

spread like wildfire, over the Internet.

It was 1987 when Steve Cook, a disc jockey at WTCM in Traverse City, Michigan, recorded

a novelty song about the Dogman, and played it on his radio station.

Listeners began to phone in, reporting their own encounters with the same creature.

The switchboard at the station was flooded with calls.

Who was there, who wasn't and why Chelsea FC trained in England ahead of MOL Vidi - Duration: 3:03.

Chelsea take on MOL Vidi tomorrow night in their final Europa League Group L match of the campaign

The Blues have already reached the knockout stages of the competition and have clinched top spot, meaning there is little riding on the match as far as results are concerned

But what the game does do is give Maurizio Sarri the opportunity to rotate his players once again ahead of the Premier League match at Brighton & Hove Albion on Sunday afternoon

Usually Chelsea will travel with the squad and train in the country that they are playing in, like they did with the visits to PAOK and BATE Borisov

However, this time the Blues trained in England at the training ground in Cobham.This game Sarri the chance to have a session with those first team players that are not needed for the match

With the group wrapped up, it gives Sarri a great opportunity to leave the key members of the first team at home to rest and then train back at Cobham on Thursday

It gave Sarri the opportunity to plan for the Brighton match, as well as getting the players ready for the game at the Groupama Arena tomorrow night

However, there were a few absentees from the group.Mateo Kovacic did not train after picking up an injury on Saturday against Manchester City and is an early doubt for Sunday

Meanwhile, Gary Cahill and Victor Moses also did not train with the side, which means both might not make the journey

Youngsters Callum Hudson-Odoi and Ethan Ampadu are expected to start the game in Budapest, while academy star George McEachran did not train but is with the squad for the trip

WHAT IS A CAPACITOR ? PART 1 | SIMPLIFIED - Duration: 12:11.

In this video I want to explain what a capacitor is

in a previous video

I used water analogy to explain the concept of voltage current and resistance and

Here, I have a garden hose that's shown in green. I have a nozzle and I have a piston

And in this hose is filled with water, which is analogous to charge Q

and as I push this

piston

To the right that's analogous to voltage that causes a current to flow out of this nozzle in this nozzle

causes a certain amount of

resistance R

To current flow now. I can use a similar analogy to explain what a capacitor is

Let me erase this

Let's consider a tank that can hold water

And

I'll draw a tank that can hold twice the amount of water

to the right

Let's say I pour a

Gallon of water into the tank at the left and

I almost fill it up and

We'll call this

gallon of water we represent that by

charge Q

Let's say I pour the same gallon of water

To the tank on the right

And it fills up this amount and it has the same amount of water the same amount of charge in

the analogy

The electrical symbol for this water tank

Is the capacitor symbol

At the right I have a still capacitor it's a bigger capacitor

The capacitor at the left I could say it has a certain value

It has a certain capacity to store charge. I could call that capacity. One fare add a

Ferret existed I

a unit of capacitance that says

What is the storage capability now? Look at this tank on the right? It has twice the storage capability

So in the capacitor analogy, this would be a two farad capacitor. I'll call f4 farad

So in the tank at the left has a 1 farad

Capacity which I'll draw this way. This has the twice the capacity at 2 farad's

So what is a capacitor capacitor is a device that stores charge

This is the just as this tank stores water the capacitor

stores charge

there's a simple equation that tells

How much charge the capacitor stores we say Q?

equals to the capacitance C times the voltage

V in our water analogy the level of the tank is

analogous to voltage

So the tank at the left I have a high voltage tank at the right the voltage is only half as much

I'll call one half V or V over 2

So if I

write the equation for

the

Charge on the capacitor at the left. I

Can say the charge in this case I port in the gown

But let's say a gallon is equivalent to Coulomb of charge. I can say this capacitor is one

Coulomb

Is equal to the capacity which is one fare ad

Times the voltage which is one

Volt which is the height of the water and the analogy

The capacitor at the right I could say has the same charge 1 Coulomb

Equals to farads

Times

One half volt so HK eats capacitor stores

one Coulomb of charge

but the

Capacitor on the right has a greater capacity and for the same amount of charge

We only get half the voltage

Let me erase this

Analogies are never perfect and the water analogy for the capacitor is not perfect either

Let's consider that for a second here. I have a tank

And I used as now an analogy to a capacitor. I fill it with water

The capacitor actually works a little differently

if I have a capacitor and

I put charge in the top a

Charge Q. I

Develop a positive

charge on the top plate and

a negative charge on the bottom plate and

as charge flows into the top

this charge also flows in

the bottom terminal same

amount of charge flow

But when I put water into the tank, it just just sits there

Q it doesn't doesn't flow out if it flowed out. I

Wouldn't have the charge in the tank anymore. So the analogy is not perfect in the capacitor

I can have a charge flow or I can have a current

Flowing this terminal and this terminal at the same time and still

Have a charge on the capacitor

So the water and algae is not perfect, but it gives you at least some sort of idea to something that you're familiar with

Let's consider what a capacitor is physically

Let's say that, I have a plate of metal

And below this plate I have another plate it's identical in size

To this top plate I

connect a

wire and

Underneath to the bottom plate. I do the same. I connect a wire and

This is what a capacitor is physically

If I induce a current into this top terminal I I

Get to turn a current flowing out the bottom terminal that's the same I

so as this current flows into the top terminal I get a positive charge on the top plate and

At the same time I get a bottom plate charge that's negative

so think of it this way as the

top plate

develops a positive charge that

repels

positive charges

From the negative plate because like charges repel each other. So

As a result I get a current flow out the bottom plate

There's a

equation

for this capacitance or for this capacitor C equals

Epsilon times the area of the plate divided by the distance between the plates

So in this case the distance between the plates is D and

The area of the plate

This is a

So what is this epsilon

This this is the Greek letter it's a symbol for

Permittivity

And permittivity is a physical characteristic of the

Region in between the place

so the

permittivity is associated with this region D in between the plates and

different

Different substances have different permittivity. X' for example

Mica might be used in between the plates and glass might be used and they're slightly different

as

the area of the plates

increase

the

capacitance increases as

the distance D

Decreases the capacitance also

increases

So in a capacitor you'd like to make D as small as possible to get the most amount of capacitance

but there

Can be a problem associated with that

Let's for a minute

Let's move this out of the way

Let's consider

The two plates and

we have a terminal and a

terminal and we send in a

current I into the top plate and that develops a charge on the top plane and

that repels

charge positive charge on a negative plate so end up with minus charge on the negative plate and

The charge has been pushed away

So the same current that flows into top plate flows out the bottom plate

but as the current flows

in the capacitor remember that

The charge on the capacitor is the capacitance times the voltage

Let's solve this for voltage voltage equals

Charge divided by the

capacitance so as we add charge to the capacitor as

the charge increases

the voltage V

increases also

so eventually

If we add enough charge of this capacitor this region in between will experience a very large electric field

This is where the energy is stored in this a field and

If the field becomes too strong it can cause this material between the plates to break down

So all capacitors will have a breakdown voltage if this D

this distance between the plates is

small

It will break down more easily if this distance is large the breakdown voltage will be higher
