thank you very much I would return today I would
I want to talk about a new one a new
way to see the world that I like
quite like seeing the world
for the lawyers there so that you can
in that phrase in Latin bag pira
operandi
normally it is used with the criminals it
use good this criminal has this way
to operate the modus operandi from this
criminal but I do not believe that if your a
engineering as modus operandi you
life is much richer
I do not say that he is an engineer that has
those three letters before your name do not I
generates a verb like English
engineering to my engineer I’m going to
engineer the transmission is not accurate
but I’m going to engineer it angola in his
level
first before you start that now not
available
the talk will be in the official language of
the abc that espanglish number 2
certain things that I speak of are not
to try at home number 3 I did not
I’m responsible for your reaction to this
talk that I had to include yawns
friends and sometimes traumatic memories of
his science classes
me here another ott my friends who saw the
presentation they said good
Roberto because you do not give him the title
the energy of Roberto because they are what
what is that we are going to talk about and in
this century that we live the nets 22 we go
growing and we are the ones that go by
world at the moment
so get used to live thanks
boys various discomforts
I am not responsible to whom I have made
I was a Mayan interpreter of the first grade
there we are in united nations
exposing chile with a friend who
everything is in contact after good that
if we compete with pet we compete with the
school I always liked engineering
he refused to science but the school and
in and betty pretty to the vehicles of
all kinds of sailboats cars cars to the
proportion goes around in the center
car and right
electric car elective cargo luxury
here
this motorcycle sas and I remember
you think they are this I think it’s a
pretty old text because to me the ones
I’ve been in 2005 but I found it cost me
find it by I found it and I remember
which it is the first time I di me
I realized that I could do an engineering
or engineer or engineer something naive
we are studying
electromagnetism and that the currents
magnetized the materials this this and
this and I go to this topic
I was distracted and I started to read
the book and this topic and I was shocked
enough because I lived a function
practice what we have learned in the
school because the school all
we learned good you put these
so many magnetto and has this force the
front 33 3 ps3 it will be and this
this is in all their houses I can not
make an announcement that you can when
there is only one overload when
someone does something and short the
magneto low waehler and short current and
pre and set fire to another other
things that happen to me but overload
for me this is I took it was a shock
well at last I have something I can do
with what I learned that is useful
Well let’s talk a little science
engineering
the base is the basis of science in the
Western world is pretty good
established are attributed such of
mileto all my books in English because
those times in ancient Greece were
I thought things go through
coincidence because the gods said that
this was going to happen to us not only did not he
they turn things around people accepted
but but such did not say there has to be
logic there must be rules and it was the
first to design the scientific challenge or
in the for the first parts of
transition and try to find
he had many theories that were were
completely false he thought that the
water was not all that everything is
formed of water
good but and but he had had at last
I had theories I wanted because I wanted
learn was risked
experiments but I like it more
curious that the many historians
they believe that he was an engineer or engineer
created the science very interesting or interesting
but here in the last two points is
as I see science engineering
sciences always consider the rules
why is the universe pear and I do not say
I can not be just chemical physics
also social sciences how do we
we behave human truth but
engineering uses science as a
tool for a concrete purpose and eye
it’s not linear is not circular because
the engineers design experiments for
scientists who find science
that engineers is a whole circle
today we are going to take from home a little the
thermodynamics
to achieve it because I think it applies
a lot of people and I’m a little bit
astral for people who have not seen
that but I love this this sentence of
Victor hugo cm that says the engine
that the steam engine taught more to the
science that the 100 that science
taught him in the engine design of
steam that right and this this I
crashes because you can say good this
it is we humans are
ingenious by nature winsin &
films and then we learn to order them
we turn it into science
Well let’s talk because I want to do it
little more vilera could then I wanted
ask what they have in common
things the calories of you that
go to jim do you think you would stay
what is how many calories what they eat
one kilowatt hour
you are a parent who pays the
invoice makes you think you know that
when the kilowatt hour has not been
presented already and jobs that the student
of physics they are going to tell me that they know
true
ok all those things are the same thing
that energy and that is the basic unit of
thermodynamics and describes how it
move the how they move as their
object object energy and that ipic and
describes physical processes
for example this here
remedy is I got it from yesterday of the of the
darfa of my aunt’s house and that is
saying how much kilowatt hour
use your refrigerator and when you put that
in the context of how many calories like
more interesting
I recommend you do it for
example you going to jim 600 calories
per hour it is quite affordable that there
many people are like a slow rhythm but
with a very fast pace but to put
about the horse is but that has its
exactly analogous to the horsepower that
for you who have car head
car force
that what they assume an hour 0.009 three
children for another
another case study that I like I like
talk a lot about that bikes
What then because we all know that
bicycles are adam but historically
they had a very large value for
peace for technology for
civilization because to me from the
late 1800s and Prince 1900 already
They began to already beginning to give those
bicycles as a standard of excellence
to the basic safety at that time but
it was the bicycles that
they pushed enough technological advances
that we use for all
air tires before
bizarre air rays
tension before this the rays were like
they are made of wood that down the bearings all
all for bicycles by bicycle
had one is another very important effect
in society and it was that for the first time
brought the mechanics within reach of
anyone who wants to be
puts to fiddling as we say here with
bicycles and if you know
that are not others that are now declared
most famous of all time
there are no problems there are towards bicycles and
they were fascinated with things that were flying
they put to study the science of
fly
and and they decided to do something crazy
they continued to leave their health zone
comfort they decided to put all their effort
in creating and creating the first the first
plus me first plane paper for the
rest history
the pib but in addition to that just to create
to create a plane to the rambo something
that people do not realize is that the
the brothers wright them before doing
any they create a wind tunnel
for you do not know that a tunnel of
wind is a little machine has a
fan on one side and the other up
a specimen will feel airy
by the force that has up
and down and that’s how they make the
many test in the wills of will
position of water and even balls of
World Cup ball to put them into
the wind tunnel to see how
reacts to buy all the
currents and formosa first links
they did that and this is science
they spent in the basement typing
the thimble coefficients of left
currents are calculating how everything is going
and another thing that I really like
bicycles is the ability that gives us
to understand ourselves because it ‘s from
the few of which was the first
machines that were used by a human being and that
the being optimized so that the one to use
a human being is we are we
engineering to be used to know by
be human here
well clear you in which in the
gym can make bicycles
stationary
but now and even people in guatemala
who uses the bicycle to shear
wash clothes to take out water
to draw water from the well to load
Everything batteries and the bicycle what
has the power that uses the power
maximum power that the human being has
in the most efficient way because here and
here I will talk a little bit this is the
power verses time is in the
power
in watts and here in red is a judge for
never a horsepower and all those
curves are curves that were put by
the nasa and they are saying that how much
time could a person last but
certain power as we talk 600
calories per hour runs corresponds
hit a certain level in the ajax is and
how much now can you do it and will it go
there they go as well as Ivan choosing
the first astronauts
Then they began to quantify
serious as had humans
power
available thuram then I have read
this and like good millennium that ‘s in
do social networks but like
bernardo that I am so I also like
correct and today a friend and she says good
14 minutes union sections I did not have
of flowers brings good
not at all with flipy equity
enrique 44.4 watts of those horses
strength like a motorcycle girl
Suffice it to say that there is better way than here
here the pac and I put it here is this
Estrellita everything was her capture
the best astronauts of the nasa
good one last anecdote that I want
talk about my personal life is not
about why we all my subjects
what grow here the British I had
a friend who loved loved
take risk
he loved he likes to bet but from
a much better way
then we are studying I remember
more yesterday and we are with a probability
to disseminate Roberto I have these I
I have this strategy for roulette and
you put that we won no no no no no
not this will work this this and this
the la the route is analyzed a game well
simple and you can define what is
called a random variable and easily
to these results or you win or lose a
Roulette has 38 spaces and your bet in
one has a own of 138 to win
78 lose if you win earns 35 of what you
you put in if you lose you lose you put in ok
if you add that and then averages you go to
lose by a & e on average 5 cents
for playing
let’s say for every hour that you see good
but not me
Messi kept bugging me
annoyed says good we’re not going to try
we are going to try
it turns out that we go and not if I believe that the
people of the people almost do not think that you are
forgot or not be it never take have I do not
I know not what he did but he good put new
rules and everything good for this month a
agreement first day that was July 4
for this month if you hit the number of
the date by 46 4th of July does not win 35
he wins 70 good ok that changes everything and the
analysis makes it easy to earn 87 cents
per dollar
and then well we played yesterday 20 minutes
he is not going to tell you what we did but
three days they did not want to enter us but
this is just to teach that if
you have to be airs calculated risk but
him but there is the the embargo always
always change always changes and has
to know how to react simply to
finish I want to tell you
I want to leave you with a short video of
steve jobs that seriously I think that sums up
which is the person that best sums up
I eat like I would like you to start
see your life or if you add and even better if
it’s in your wife and goodman and
[Music]
white white world cheese awards in areas
avoid wife then meira for the team
mark hughes in bedbugs and get funds
and urgent or take a team that mills and
manatee and where to live without it
if then that’s why I tell everyone that
I’m going to see if anyone this is all
what is in this world has done
someone else
that person does not have anything special
compared to you
you can do it you can do it
better it can be different when you
you realize that
the world changes year took maybe 20 years
and I hope that some of you that such
Once they are having 12 13 realize
that
very soon and you save seven years that I
that it took me to find it
thank you very much
[Applause]
