Fieldbus isn't really one thing

but more of a collection of things.

Fieldbus is a group of protocols

that are used in the industrial arena.

The Fieldbus protocols have been standardized as IEC61158.

Basically, Fieldbus works on a network

that permits various topologies

such as the ring, branch, star, and daisy chain.

Prior to Fieldbus, industrial controller systems were connected

using RS232 serial communications.

As you know, serial communications allowed only two devices to communicate.

Whereas today, the Fieldbus connections

are more closely compared to the typical Ethernet connections

where you can connect multiple field devices

to a single connection point

that would then connect to the controller.

However, Fieldbus is not a connection type, per se,

but instead, a description used

to indicate a group of protocols.

There are several protocols in the group

such as ControlNet in the Allen Bradley family,

Modbus, Profibus, EtherCAT, HART, CIP, and many more.

A primary benefit of Fieldbus is for field connected devices.

For instance, consider you have several field devices

that are quite a distance from your computer.

With Fieldbus devices such as sensors, motors,

lamps, switches, these devices are connected to an I/O data block,

which is then connected to a field distribution device,

which is connected to a Fieldbus power supply,

then finally connected back to the controller.

The connections to the Fieldbus components,

with the exception of the field devices themselves,

are single cable connections.

This connection scheme may vary depending on the

Fieldbus protocol that you are using.

This type of field device connection saves on wiring runs

that would have to go all the way back to the controller.

As you can see, this type of device wiring

would have many benefits when the distance is an issue.

As you can imagine, your controller system

will need to have a communications module

that will be able to establish communications with the field devices.

In the case of ControlNet, you would need a ControlNet module,

Profibus would need a Profibus module, etc.

This is not to say that every protocol is dedicated

to a particular manufacturer

and must connect to the proprietary controller.

For instance, Profibus is a widely used protocol

that can connect to Allen Bradley, Siemens, Modicon, etc.

The same applies to the universal protocol of Modbus.

However, some protocols do not play well with others.

ControlNet is an example that cannot integrate into a Siemens processor.

With this information, as you can see,

there should be great care taken when designing your plant control system,

including the communications network,

and specifically the device layer if considering Fieldbus devices.

Do your research and make sure that all family members

like each other and are willing to communicate together.

What Should Have Happened to Earth When Master Roshi Destroyed the Moon? | Dragon Ball Code - Duration: 3:36.

When Goku was fighting master Roshi in the Tenkaichi Budokai and became a great ape,

master Roshi had no other option, but to blow up the moon to reverse the transformation.

Well, I guess that wasn't his only option, he could've gone for the tail, but he instead

he went for the moon.

But when he blew up the moon there were no changes on earth.

It was just like nothing had ever happened.

The reality is that the moon is very important for earth.

So today we're going to see what should've happened on earth when master Roshi destroyed

the moon.

Hey how's it going my name is Raf and welcome to Dragon Ball code.

Today we are going to be taking about what should've happened on earth when master Roshi

destroyed the moon.

And if your first time here and you like Dragon Ball content consider subscribing because,

this channel is all about Dragon Ball.

So like I said before master roshi was fighting Goku in the tournament and all the sudden

Goku looked at the Moon and he transformed into a great ape.

Goku clearly had the advantage, but he was out of control.

Master Roshi not seeing any other way around it, he shot a Kamehameha at the Moon and blew

it up.

A little bit drastic if you ask me.

Then Goku was able to go back to normal, but now the moon was gone.

So when master Roshi blew up the moon the first thing that should've happened would

have been a bunch of pieces from the moon falling into earth like meteors.

This wouldn't have destroyed the Earth, but it would've caused a lot of damage, tsunamis

and could have potentially killed a bunch of people depending on how big the pieces

were and where they landed.

The pieces that did not fall on earth would start forming a ring around the Earth like

the one that Saturn has, and because of this, the earth would have a bunch of meteors coming

down frequently.

Another thing that should have happened would be that the oceans would not have tides anymore.

This would affect the ecosystem of the oceans and a lot of species would be in danger.

Another thing is that a day instead of being 24 hours, would be about 6 to 12 hours.

Because the moon is the one that slows the earth down with gravity making days longer.

By not having the moon anymore, the earth would start to speed up making the days shorter.

That wouldn't to be the only thing affected by speed, as a consequence of spinning faster,

winds on Earth would be a lot faster as well and I'm talking at about 100 mph and then

when hurricanes appeared they would have even stronger winds.

An obvious one would be that the nights would become much darker making the stars even brighter.

That would make nights even prettier, but that would be the only thing that would be

nice to see.

Another bad thing would be that the earth would slowly start to tilt more than it supposed

to.

This would make weather crazy and unpredictable.

Places that never see snow would get snow and places that are always cold would be hot.

Just with this tilt there would be natural disasters all the time.

And if it didn't tilt at all.

There would be no seasons.

The whole year would be the same.

Those are some of the things that should've happened, then when Kami returned the moon,

everything would start falling into place with the exception of the ring of rocks around

the earth.

But then piccolo blows of the moon again when gohan transforms.

And the same stuff would start to happen again.

But this time the amount of debris falling from the sky would be a lot more making it

even more dangerous.

There are many more things that should've happened on earth when the moon blew up, but

these are just some of the bigger ones.

So master Roshi blowing up the moon was pretty reckless.

And also piccolo, but Piccolo was mean at first so something like that it would be expected

from him.

But not from someone as wise as master Roshi.

And there you have it

What will people experience when they see Clueless the Musical? - Duration: 3:10.

The musical does not let down. It gets all the gems, all the one-liners from the

movie, are put in there, you know, for the fans, but then, there's a couple twists

you wouldn't expect, a couple little new rewrites and interesting storyline

changes that'll keep people intrigued and entertained. I think that they're gonna

love it.

Well, it's cool to see, like, they're gonna be like, "what's a pager" and

like, "What's a flip phone, what is that?" so it's good to get, like, what we went

through growing up.

I think that everybody can kind of fall in love with

it in a new way. If you are a huge die-hard fan of the original, we have

all of the classics, we got your favorite lines, we have your favorite characters,

we're hitting the costumes, and then we're also putting our own twist on it.

Everyone's version of their character, no one's going for the original way that

it was presented. Everyone's able to put their own spin on it and I think that new

people that haven't seen this before are gonna have to go back and

see the original, and I think it'll be a nice melding of the two.

I definitely

think that it's funny and energetic and that people who have seen the movie will

definitely love it, and anybody who lived through the 90s is gonna like, lose their

minds because it is such a great reminiscing experience.

There's a

beautiful heart to this show that I think people are gonna really fall in

love with. There's a reason why this movie has lasted for so long, and the

musical absolutely carries on that tradition and brings it to a new

audience, a younger audience, fresh ears, fresh eyes and the music that we're

doing... I mean, I get to sing some of the greatest, like, 90s hits that I would sing

in the car when I was a kid, you know, driving down with my friends, and to get

to sing those on stage... it's a dream come true, it's amazing.

I think we do a

really good job of, like, satisfying both. Because you don't have to have seen the

movie, you don't have to come in with any point of context other than wanting to

have a good night of theater. And you will have a good night of theater but if

you want to see Clueless on stage too, you'll have that. We got both, you know?

I think that we have done, so far, a really good job putting what the

longtime fans of Clueless the movie, I feel like we've translated that really

well to the stage, so I think that they're gonna be really excited. I hadn't

even thought about the fact that this will be some people's first experience

with Clueless, and I think that, not only are they going to love this story, but

it's just gonna make them want to go home and watch the movie.

I think if you

love the movie, you'll, like, 100% be obsessed with the musical. Amy Heckerling

is involved in the process, so it is the movie, like, on stage, which I feel like is

fun, and it's a 90s throwback musical, which everybody can, like, love and enjoy,

It hints at the original, but it's also very new, and I think the 90s songs that

are in it will also, I feel like they're gonna blow their minds with like, you

know, when you hear that song you're like, "Oh, no way! That song is in the show?" and

I think that's gonna really win over the crowd.

If they've come to the show

already being a fan of Clueless, they're gonna get a next level of enjoyment and

understanding of this movie that I'm sure they've grown up knowing and loving.

MEDELLIN TRAVEL GUIDE: What to Do & Eat + History | Colombia Ep 2 - Duration: 10:20.

After a wonderful introduction to Colombia in the capital city of Bogota, we're heading

up north to Medellin.

People from Medellin are proud of their Paisa culture and heritage and are well known for

their entrepreneurial spirit, hospitality, and their beautiful metro system.

Back home in Boston, I teach English to adult's part-time and a number of my students from

Colombia are from Medellin.

For all of these reasons and more, we were excited to explore this unique part of Colombia.

So another day, another beautiful park in Colombia.

This time we are in Medellin.

And we went up north from Bogota, but we dropped about 4,000 feet in elevation, and at least

for me, it's actually pretty noticeable.

So one of my favorite things to do when I'm traveling in a new city is to go check out

the grocery store.

I find it infinitely fascinating to walk around and see what types of foods are on offer at

the local grocery stores.

Plus, you can pack up a few things, throw it in a bag, and then come to a beautiful

park like this one in Medellin.

And enjoy the views, while you have some empanadas or some apples.

Whatever you want.

How's your apple?

What are we doing here?

Having lunch.

We're having a little picnic.

I got a charcuterie, a little cheese, a little chorizo, a little jamon.

Very good.

She's practicing her Spanish.

She listened to a few podcasts on the way from Bogota to Medellin.

So, that's great.

We're both learning a bit and trying as much Spanish as we can.

How do you say "apples" in Spanish, in Espanol?

Como se dice "apple" en Espanol?

No se.

But it's a good way to just get out in thee, get out in the open, get out in the green

spaces of whatever city and have a nice little meal.

And also saves a lot of money, its very cheap to just go to the grocery store and put together

a little picnic for yourself.

Try it out, wherever you are.

John, how many empanadas did you just eat?

How many empanadas did I just eat?

Umm... uno, dos tres, three.

I had three empanadas.

I'm not ashamed of that.

The empanadas here are fantastic wherever you get them.

On the street, in a grocery store, wherever.

They're great.

When you're in Medellin, make sure you get on a walking tour with Real City Tours.

This particular tour came highly recommended by my good Aussie friend, Desmond, and it

didn't disappoint.

Our guide gave us great history on Medellin's beginnings as the manufacturing hub of Colombia,

it's darker days in the 80s and 90s when a certain infamous drug-lord was terrorizing

the city and one of the most remarkable transformations you'll see anywhere in the world since.

Emerging from the aforementioned darker days, Medellin over the last two decades has become

a vibrant center for innovation, world-class art and coffee, and one of the fastest growing

economies on the continent.

Walking around the city, it's easy to tell how much its residents take pride in its entrepreneurship,

unique architecture, and their public art installations that all give this city a great

community vibe.

As you can see, Medellin is a city that takes pride in its art.

After some of the issues that they had in the 90s and 2000s, they really wanted to develop

the city to make it beautiful, and really highlight a lot of the artwork so some of

the spaces that you see here were some the most difficult parts of the city as far as

crime is concerned, and now you can see they've turned some of these buildings that were notorious

for crime in really beautiful spaces that house their government and a lot of artistic

pursuits of the citizens of Medellin.

Here in his hometown, Fernando Botero has his own plaza, which truly is a feast for

the eyes.

Here you can find his beloved depictions of nude men and women, cats, and even an oversized

baby head.

So, walk around and enjoy the sights and sounds of this beautiful outdoor gallery, all for

free.

Alright Erin, we're in the center of Medellin, what are going to buy right now?

Un bunuelo.

Bunuelo.

Deep-fried cheese ball.

Deep-fried cheese ball.

Alright, make it happen.

Alright, give it a try.

Very good.

Now that we've gotten a bite to eat, it's time to check out one of Medellin's claims

to fame: I'm admittedly a bit of a public transportation geek, if that's even a thing,

but Medellin's metro system is continent-renowned.

Opening in 1995, Medellin boasts the only metro in Colombia.

Speaking to locals about it, they take great pride in this distinction and you can tell

as the metro itself and its stations are sparkling clean at all times and they run incredibly

effeciently.

Those of you who have seen our Bogota video know that Colombian's love a cable car.

In my humble opinion, however, Medellin's cable cars are even cooler and more enjoyable

than Bogota's.

While the ride up to Monseratte in Bogota is short and sweet on one route, Medellin

features multiple routes.

There's a series of cable cars moving up to the west of the city which go over Comuna

13, or Comuna Trece, formerly known as statistically the most dangerous neighborhood in the world

over 20 years ago, but we took the cable cars moving up to the east that go all the way

to Parque Arvi, which is an ecological nature reserve.

The cable car takes about 30 minutes to get up to Parque Arvi, and a round-trip ticket

costs less than $3.

It's genuinely shocking how quickly the landscape shifts from urban sprawl to the woodlands

stretching over the Andes as far as the eye can see.

Both the metro and the cable cars in Medellin are important symbols of the city's pursuit

of economic equality, as when opened, they connected the lower income and the wealthier

parts of the city directly for the first time.

So, we made it, we're on top of the hill now, Parque Avri, and it's amazing once you get

up here the change in temperature, the change in smell.

It just feels crisp and clean and much like the rest of the city it's very beautiful up

here.

And they've done a really nice job of putting together these little...

I guess it kind of tells the story of this place and lets you know sort of the flora

and the fauna that exist up here, and just a really cool learning experience.

They have a little market, a little mercado, and you can be some nice snacks and also little

handmade gifts, and it really just does a nice job of demonstrating what this national

park is all about, and what it means to the Colombian people.

And if you have a good grasp of Spanish, then you can understand it by reading those little

boards over there.

Uh we'll have to take photos of those and do a little translation later and learn a

little more about the park ourselves.

Either way, its well worth the trip up here.

The gondola ride was a lot of fun.

You get to see a really cool perspective of the city.

And then once you get up here its just you and some nature.

And, Colombian nature at that.

A lot of beauty in this country to behold.

And a lot of beauty in the people that come to visit it.

Now before we end this video, it's important that we sample a local favorite; an alcohol

that literally translates as fiery water…

Erin?

Welcome to beautiful Medellin.

We are here amongst the beautiful mountains and we're about the have a very authentic

Colombian experience with our liquor that comes in a juice box.

John, what is this called?

Aguardiente?

Arguardiete.

Si.

Si.

And its supposed to taste like liquorice, which sounds lovely.

Okay, I'm going to try it out here.

I don't really want to do this.

Salud!

That was terrible.

Tell us what you really think.

Colombia, liquor in juice boxes.

Thanks so much for checking out our Colombia videos the first travel videos I've ever

made.

If you like these, be sure to like and subscribe to my channel as we've got great trips coming

up including our next stop in Oslo, Norway.

That's what we were looking for.

Oh ya.

What would happen if a tsunami hit BC's Sunshine Coast? - Duration: 3:46.

What would happen if the BC Sunshine Coast was struck by a tsunami?

According to the National Weather Service, there are an average of two tsunamis each

year that cause damage near their source.

This means that unlike hurricanes, tornadoes, or forest fires, tsunamis are a much rarer

occurrence.

This fact alone means the risk of a tsunami hitting the Sunshine Coast is very low.

But what if the worst did come to happen and we were one of the two unlucky locations to be

struck by a tsunami?

A 2006 study by EmergeX Planning for the SCRD explains that because of our location, the

run-up potential for our region is less than two metres.

Run-up is the amount of seawater that could be pushed up above normal sea level during

a tsunami.

Maps on the SCRD website illustrate potential inundation areas along the Sunshine Coast.

These examples theorise what would transpire should a 10-metre wave hit our shoreline.

Gibsons would escape with relatively little damage.

While the marina and infrastructure and property along Marine Drive would likely be devastated,

most of the town wouldn't feel the direct consequences of a large, 10-metre tsunami.

The destruction in Roberts Creek and Wilson Creek would be more wide spread.

In Roberts Creek, 10 metres of water is shown to reach as far up as Highway 101.

The pier, beaches, and shops and restaurants would probably take heavy damage.

Wilson Creek would be in the same boat.

Because of its relatively flat elevation, water would reach past the highway and invade

the shopping plaza, the car dealership, and Canadian Tire.

Damage to property and infrastructure could be immense.

Further up coast, Sechelt and Pender Harbour would appear to be the hardest hit by our

hypothetical tsunami.

Large swathes of central Sechelt would be decimated, and the northern part of the peninsula

would likely be completely cut off from the rest of the province until the waters receded.

As the EmergeX report points out, much of the District centre is flat and home to critical

infrastructure.

This is compounded by the limited sheltering of the local offshore islands.

It's a similar story for Pender Harbour where many parts of that community would find themselves

underwater or cut off from the rest of the region.

So, what should you do when you hear there's a tsunami warning for the Sunshine Coast?

Ready.gov provides these safety tips.

If you're on land, head towards high ground that's as far inland as possible and stay

there until officials tell you it's safe to return.

If you're in the water during a tsunami and it's impossible for you to reach land, find

anything that floats and just hold on tight.

POLICE: We'll get him when he comes back in!

JOHNNY UTAH: He's not coming back...

If you are in a boat, then face the direction of the waves and head out to sea.

However, if you're in the harbour, head to shore instead.

EMMA: We're gonna make it! We're gonna make it!

TONY: SCREAMS

When the tsunami retreats, there'll likely be flooding and damage to infrastructure and

property.

Do your best to avoid floodwaters as they'll be full of debris and additional hazards could

be hiding just under the surface.

While is a tsunami hitting the Sunshine Coast is exceedingly unlikely it's always best to

be prepared for any emergency.

You should have an emergency kit at home, at work, and in your car.

You should also contact your insurance company and double check your coverage for things

like an earthquake, flooding, and yes - of course - a tsunami.

NFL Overtime Rules Playoffs: What Happens When Teams Tie? | Heavy.com - Duration: 6:03.

NFL Overtime Rules Playoffs: What Happens When Teams Tie? | Heavy.com

The NFL playoff overtime rules are similar to the regular season with one main difference, a game cannot end in a tie.

The game initially heads to a 10-minute overtime period and if the game is still tied it goes to another overtime period.

During the regular season, both teams would be awarded a tie in the standings.

The first team to possess the ball in overtime can still win the game with a touchdown.

In most circumstances, this means it is preferable to choose to receive the ball if a team wins the coin toss.

Unless a touchdown is scored on the first possession, both teams must possess the ball once.

After both teams have possessed the ball, the first score wins the game.

A field goal or safety can only win the game once both teams have been on offense at least once.

Here's a look at the traditional overtime rules per NFL.

com.

At the end of regulation, the referee will toss a coin to determine which team will possess the ball first in overtime.

The visiting team captain will call the toss.

No more than one 10-minute period will follow a three-minute intermission.

Each team must possess, or have the opportunity to possess, the ball.

The exception: if the team that gets the ball first scores a touchdown on the opening possession.

Sudden death play — where the game ends on any score (safety, field goal or touchdown) — continues until a winner is determined.

Each team gets two timeouts.

The point after try is not attempted if the game ends on a touchdown.

If the score is still tied at the end of the overtime period, the result of the game will be recorded as a tie.

There are no instant replay coach's challenges; all reviews will be initiated by the replay official.

During the NFL Playoffs, the Game Will Go Into a 2nd Overtime Period If the Contest Is Still Tied.

Unlike the regular season, each playoff game must have a clear winner in order to advance in the playoff tournament.

If the game is still tied at the end of one overtime period, the game will go into a second overtime period.

The second overtime period is treated similarly to when a game goes into the next quarter during regular play.

There is only another coin toss if a third overtime period is required.

Here's a full rundown of the NFL playoff overtime rules per NFL.

com.

If the score is still tied at the end of an overtime period — or if the second team's initial possession has not ended — the teams will play another overtime period.

Play will continue regardless of how many overtime periods are needed for a winner to be determined.

There will be a two-minute intermission between each overtime period.

There will not be a halftime intermission after the second period.

Another coin toss will be held before the third overtime period.

The captain who lost the first overtime coin toss will either choose to possess the ball or select which goal his team will defend, unless the team that won the coin toss deferred that choice.

Each team gets three timeouts during a half.

The same timing rules that apply at the end of the second and fourth regulation periods also apply at the end of a second or fourth overtime period.

If there is still no winner at the end of a fourth overtime period, there will be another coin toss, and play will continue until a winner is declared.

What is motion in physics? - Duration: 8:25.

In physics, motion means a continuous change in the position of a body relative to a reference

point, as measured by a particular observer in a particular frame of reference.

Until the end of the 19th century, Newton's laws of motion, which he posited as axioms

or postulates in his famous Principia, were the basis of what has since become known as

classical physics.

Calculations of trajectories and forces of bodies in motion based on Newtonian or classical

physics were very successful until physicists began to be able to measure and observe very

fast physical phenomena.

At very high speeds, the equations of classical physics were not able to calculate accurate

values.

To address these problems, the ideas of Henri Poincaré and Albert Einstein concerning the

fundamental phenomenon of motion were adopted in lieu of Newton's.

Whereas Newton's laws of motion assumed absolute values of space and time in the equations

of motion, the model of Einstein and Poincaré, now called the special theory of relativity,

assumed values for these concepts with arbitrary zero points.

Because (for example) the special relativity equations yielded accurate results at high

speeds and Newton's did not, the special relativity model is now accepted as explaining bodies

in motion (when we ignore gravity).

However, as a practical matter, Newton's equations are much easier to work with than those of

special relativity and therefore are more often used in applied physics and engineering.

In the newtonian model, because motion is defined as the proportion of space to time,

these concepts are prior to motion, just as the concept of motion itself is prior to force.

In other words, the properties of space and time determine the nature of motion and the

properties of motion, in turn, determine the nature of force.

In the special relativistic model, motion can be thought of as something like an angle

between a space direction and the time direction.

In special relativity and Euclidean space, only relative motion can be measured, and

absolute motion is meaningless.

So comment, what do you think, which model is best for describing motion.

An object is in motion when its distance from another object is changing.

Whether the object is moving or not depends on your point of view.

For example, a woman riding in a bus is not moving in relation to the seat she is sitting

on, but she is moving in relation to the buildings the bus passes.

A reference point is a place or object used for comparison to determine if something is

in motion.

An object is in motion if it changes position relative to a reference point.

You assume that the reference point is stationary, or not moving.

Let's give some love to one of the greatest scientists ever lived and described Newton's

Laws of Motion.

Sir Isaac Newton's three laws of motion describe the motion of massive bodies and how they

interact.

While Newton's laws may seem obvious to us today, more than three centuries ago they

were considered revolutionary.

In formulating his three laws, Newton simplified his treatment of massive bodies by considering

them to be mathematical points with no size or rotation.

This allowed him to ignore factors such as friction, air resistance, temperature, material

properties, etc., and concentrate on phenomena that can be described solely in terms of mass,

length and time.

Consequently, the three laws cannot be used to describe precisely the behavior of large

rigid or deformable objects; however, in many cases they provide suitably accurate approximations.

Newton's laws pertain to the motion of massive bodies in an inertial reference frame, sometimes

called a Newtonian reference frame, although Newton himself never described such a reference

frame.

An inertial reference frame can be described as a 3-dimensional coordinate system that

is either stationary or in uniform linear motion., i.e., it is not accelerating or rotating.

He found that motion within such an inertial reference frame could be described by three

simple laws.

The First Law of Motion states, "A body at rest will remain at rest, and a body in motion

will remain in motion unless it is acted upon by an external force."

This simply means that things cannot start, stop, or change direction all by themselves.

It takes some force acting on them from the outside to cause such a change.

This property of massive bodies to resist changes in their state of motion is sometimes

called inertia.

The Second Law of Motion describes what happens to a massive body when it is acted upon by

an external force.

It states, "The force acting on an object is equal to the mass of that object times

its acceleration."

This is written in mathematical form as F = ma, where F is force, m is mass, and a is

acceleration.

The bold letters indicate that force and acceleration are vector quantities, which means they have

both magnitude and direction.

The force can be a single force, or it can be the vector sum of more than one force,

which is the net force after all the forces are combined.

When a constant force acts on a massive body, it causes it to accelerate, i.e., to change

its velocity, at a constant rate.

In the simplest case, a force applied to an object at rest causes it to accelerate in

the direction of the force.

However, if the object is already in motion, or if this situation is viewed from a moving

reference frame, that body might appear to speed up, slow down, or change direction depending

on the direction of the force and the directions that the object and reference frame are moving

relative to each other.

The Third Law of Motion states, "For every action, there is an equal and opposite reaction."

This law describes what happens to a body when it exerts a force on another body.

Forces always occur in pairs, so when one body pushes against another, the second body

pushes back just as hard.

For example, when you push a cart, the cart pushes back against you; when you pull on

a rope, the rope pulls back against you; when gravity pulls you down against the ground,

the ground pushes up against your feet; and when a rocket ignites its fuel behind it,

the expanding exhaust gas pushes on the rocket causing it to accelerate.

If one object is much, much more massive than the other, particularly in the case of the

first object being anchored to the Earth, virtually all of the acceleration is imparted

to the second object, and the acceleration of the first object can be safely ignored.

For instance, if you were to throw a baseball to the west, you would not have to consider

that you actually caused the rotation of the Earth to speed up ever so slightly while the

ball was in the air.

However, if you were standing on roller skates, and you threw a bowling ball forward, you

would start moving backward at a noticeable speed.

The three laws have been verified by countless experiments over the past three centuries,

and they are still being widely used to this day to describe the kinds of objects and speeds

that we encounter in everyday life.

They form the foundation of what is now known as classical mechanics, which is the study

of massive objects that are larger than the very small scales addressed by quantum mechanics

and that are moving slower than the very high speeds addressed by relativistic mechanics.

How Klopp reacted to Man City defeat - and what happens next - Duration: 6:00.

 Manchester City players and fans celebrated as if a cup final had been won. The Liverpool travelling support saluted their shattered heroes in an act of defiance and appreciation

 And parts of social media began a finger-pointing exercise that degenerated into the usual cesspit of putting a flame to a player's shirt and casually doling out empty death threats

 For Jurgen Klopp, though, there was to be no ranting and raving. No shouting or screaming

 Instead, Liverpool's 2-1 defeat at the Etihad on Thursday gave him enough reasons to be encouraged his players remain on the right path – even if there are lessons to be learned from a setback that cut their lead at the top of the Premier League table to four points

 "The boys have played especially in the last month outstanding football," says the Reds boss

 "If I go in (the dressing room) after we've lost one game and lose completely the plot, that would not be too cool

 "I'm pretty similar after games. I don't celebrate in the dressing room usually, it's really rare that I shout around after a game

Usually I take a day or night to think about the things I saw and then I speak to the team

 "Sometimes I do it directly after the game and against City I did if directly after the game

Video Loading Video Unavailable Click to play Tap to play The video will start in 8Cancel Play now  "After games I'm just realistic

I say what I have to say, it's not that the boys aren't too smart and I come in and say 'everything is brilliant, who cares about the points'

That would be silly and wouldn't work."  While some sections of the Liverpool fanbase reacted angrily to the result, Klopp saw little reason for negativity after a pulsating encounter with the two Premier League front-runners

 "My assessment of the game was positive," he adds. "Not the result, but the game

Was it perfect? No. We have to talk about that.  "Could we have defended the second goal? Yes, we have to talk about that

The last line higher up and stuff like that. Should I expect perfection? I would love to but sometimes these things don't work out

That's completely normal.  "There were moments where we could learn, 100%. We could have calmed down the game a bit earlier, we could have started differently

That's all clear. But it was one game.  "We don't have to make a big fuss about it if there is no real issue

If we'd have played badly and lost 5-0, that would have been for sure different.  "I wasn't only positive after the game but I was for sure not negative

Take it like it is. If you must learn, learn from it."  Liverpool's Premier League challenge has been put on hold until next Saturday's trip to Brighton and Hove Albion, with the focus now on Monday's FA Cup third round visit to Wolverhampton Wanderers

 It will be a very different Reds side that steps out compared to the one that secured a hard-earned 2-0 victory at Molineux on the Friday before Christmas

 Klopp acknowledges the draw could have been kinder to Liverpool but hasn't considered whether an immediate return to top-flight action would have been preferable

 "I don't think about things I can't change too much," he says. "It's like it is

Video Loading Video Unavailable Click to play Tap to play The video will start in 8Cancel Play now  "It's not like I feel that we have to react immediately in the league because that would feel a little bit like we are insecure about ourselves and don't know how it will happen

 "When the draw came out and we saw we were playing Wolves, we were like 'wow, thank you very much, away'

 "Then we played there, it was really difficult and 'oh my god, we have to come back again'

It's a really tough draw and nobody was looking forward to that at the moment of the draw

Keep up to date with the build-up to Liverpool's FA Cup tie and all the latest transfer news here  "Then Brighton comes up after that

It's always a tough place to go and they are having a fantastic season.  "Do we want to play Brighton directly after Man City? I don't know as I didn't think about it

We have now between the Premier games about nine days and in between is a very, very tough FA Cup game

"

Horário das aulas nas escolas brasileiras - What time are the classes at the Brazilian Schools? - Duration: 3:57.

Good morning, good people from all over this world, how are you?

My name is Luiza, this is BRAZIL COM S, and here we discuss a little about

aspects of Brazilian life, some habits, some cultural characteristics

and also information about the Brazilian daily life.

Today I'm going to talk about class schedules in Brazilian schools.

It is interesting (for those who do not know about it) to say that Brazilian schools usually

work in shifts.

That is, they offer their classes either in the morning or in the afternoon

- and sometimes in the evening. Let's take our High School students as an example.

We have high school students in public institutions who study at night,

often because these students need to work during the day.

The morning shift usually starts around seven o'clock in the morning.

There are even some studies that want to prove that this early timetable is not very beneficial,

especially when it comes to teenagers,

but in the meantime, schools continue to offer this timetable: approximately

at seven, seven-fifteen in the morning.

And morning shift classes usually finish around noon and a half,

noon forty-five, one o'clock, depending on the school.

The morning shift is commonly attended by elementary and high school students,

and in the afternoon shift, which usually starts around one o'clock,

one-fifteen, one-thirty in the afternoon, depending on the school, it is most common to be offered

to those younger students, the ones in the Early Childhood Education, or the early years of Elementary School.

These afternoon classes usually end at five-thirty, five-forty, or six o'clock in the afternoon,

depending on the school.

Of course, we also have full-time schools, but they are not common.

In the last census we had – numbers from 2017 - about 13 percent of the students

between Kindergarten and Elementary School attend this type of school,

and then we are talking about public and private schools, so it is still a low number.

And as far as high school is concerned, the number is even lower: approximately eight

million students enrolled in high school in 2017 and only 7.9 percent of these students

attending full-time schools.

The national education plan - We have a plan that defines the educational guidelines,

and the latter is a plan that defines the guidelines and the goals from 2014, when it was created,

until 2024 - it aims to offer up to 2024 50% of full-time schools,

but this is not our reality today.

Well, I think it's interesting, especially for those who think about moving to Brazil

or maybe someone who is being transferred to Brazil to understand how it works,

the class schedule in the Brazilian schools.

I hope to have collaborated… See you next video!

A big hug!

Man Goes 50 Days Without Food, And This Is What He Learned - Duration: 5:12.

The practice of intermittent fasting has gained a great deal of interest in recent years,

considered one of the latest 'fad' diets.

However, as more and more people give this a try, pushing the boundaries and testing

limitations, how far is 'too far'?

Intermittent fasting refers to an eating routine that alternates between set periods of fasting

and eating over the course of the week.

While many experts will encourage fasting up to 16 hours each day, eating only in a

small window in order to experience the benefits, others will encourage a 48 to 72-hour period

of fasting each week, eating normally the remaining days.

Fasting has been associated with a number of great benefits including promoting weight

loss, a decreased risk of diseases including cancer, regulation of blood sugar levels,

and improved heart health.

While most scientists and experts will agree that there are benefits to be seen from short

periods of fasting, the problem lies in how our society handles any weight loss solution.

If 16 hours is good, and some experts are recommending 72 hours, then pushing yourself

to go longer would be even better, no?

Furthermore, the diet is being marketed by many as a quick fix without having to make

any other changes in your life.

Who wouldn't love the idea of eating as much as they want of whatever they want for

days on end if the only catch was not eating for 2 days each week and you would lose weight?

It sounds too good to be true!

Spoiler alert: It sounds too good to be true because it IS.

As with any other effort to improve our health and well-being, a well-rounded approach is

required.

You can't just hit the gym and expect to lose weight, for example, if you aren't

improving the quality of the food you're eating.

In this same way, supporters of fasting explain that it's only one part of a bigger picture.

True to form, a viral story has been making its way around social media, sharing the first-hand

account of Giovanni Bartolomeo, a man who decided to engage in an extreme long-term

fast.

In fact, at the time of the article, he stated he had already successfully fasted for 53

days and counting.

Interested in the benefits of longer-term fasting, including reports of altered states

of consciousness, Bartolomeo started researching some more extreme options when he came across

the Master Fast.

What is the Master Fast System?

Described as an 'extended fast', the Master Fast System outlines a schedule of alternating

dry fasting (no food or water) and juice fasting for a longer period of time.

In fact, the documentation Bartolomeo located recommended doing the fast for a total of

108 days.

A little intimidated by this length of time, he instead set his personal goal for 40 days

which was said to be the minimum length of time necessary in order to get a full cleanse

of the GI tract.

Throughout Bartolomeo's account he shared each of his experiences, from his obsession

with food and what he planned on eating when the fast is completed to the aches and pains

that he read were his body healing old sport injuries (although he doe s acknowledge that

he isn't sure how to verify this claim scientifically).

Reading up about the 'breatharian' theories stating that we actually get our energy from

the air and the gases within it, not the food we're eating, he practiced deep breathing

exercises every day.

Eventually, the obsession with food subsided he reported, writing "Around the 30-day

mark my food addiction had subsided, and I was at peace with not eating."

While his account is largely positive, discussing the benefits he experienced, there are risks

and concerns to consider with such a long-term decision.

It appears that after careful consideration, Bartolomeo felt that these also needed to

be addressed, adding the following update:

"After a lot of reflection I probably would advise against this long a fast to anyone

or do it this way again myself.

I think shorter more frequent fasting is the way to go.

A very long extreme fast may be beneficial in some cases of extreme sickness where all

other options have been exhausted.

This can't replace a healthy diet and frequent fasting."
