>> We did ours on the social
responsibility of technology.
Basically, the social
responsibility of technology
should be to solve a problem.
Any technology that's created,
generally is used to solve a problem.
There are many bad technologies
that have been created.
Some of those in history
are the Zyklon B, Agent
Orange, and Sarin gas.
Zyklon B was developed
by a Jewish scientist
named Fritz Haber.
It was the preferred method of execution
during the Holocaust.
It is responsible for an
estimated 1.2 million deaths.
Agent Orange's creator was a man
named Arthur Galston.
It was a,
He created an herbicide that was given
to the U.S. government,
and sprayed on the Vietnam.
Caused 400 thousand deaths.
And disabilities.
500 thousand birth defects.
Sarin gas, Dr. Gerhard Schrader
was hoping to help fight
against world hunger,
by specializing in new insecticides,
and he accidentally created nerve gas,
sarin and tabun.
Not every technology, man-made, is bad.
Some inventions are good.
Like cars, airplanes, GPS.
Cars were developed for
short and mid distance
transportation of people.
Americans take 1.1 billion trips per day,
average 11 billion miles a day.
Airplanes were developed for long distance
transportation of goods and services.
They help get people around the world,
faster than any other way.
There's approximately 1.7 million people
fly per day.
Without GPS, people would
be lost all the time.
GPS helps guide airplanes safely,
and ensures people find
where they're going.
GPS has helped to make
traveling safer and easier.
>> Hi everyone.
I want to let you,
explain about x-ray technology.
Not many people know about that.
about x-ray,
advantages and disadvantages
of x-ray technology.
With x-ray technology
electromagnetic radiation
laser enter into your body
and they will capture the pictures
of the part, what the doctor prescribing.
And many doctors use this technology
to verify the problem and
to check it.
The advantages for this technology,
that it is very useful to
investigate the problem,
but sometimes to the patient,
they can, by using this technology,
they can find the problem,
and they'll prescribe what to do,
and what not to do.
That is doctors.
And the disadvantages
of this technology is,
by using many, I mean,
many times of these x-rays
there is a lot of problem to human
because if you use, like,
high frequency energy
to take the images of the body.
So, my suggestion is and
many reports that there are,
for pregnant lady
we should not use x-rays
and scanning many times,
because
it will make,
not to make the growth of baby,
because the frequency
that makes a problem.
That's what I wanted to
report about technology.
>> I'm talking about nuclear technology.
It is a technology which involves
in the reactions of atomic nuclei.
Notable nuclear technologies are
nuclear reactors, nuclear
medicine, and nuclear weapons.
Nuclear energy is used
to produce electricity.
And advantages of nuclear energy are,
It is expense,
less uranium is required
to produce same amount of electricity,
compared to fossil fuels and oil.
And there is no greenhouse effect gasses,
rather nuclear does not
have some emissions which
not give off greenhouse gasses.
The disadvantages of nuclear energy
are raw materials.
You don't use in the process of fusion,
because it has a lot
naturally unstable element.
Water pollutant, nuclear fusion
And it has more water pollutions
because of this nuclear energies,
and it has over time
stays in the wind,
finisher splitting the results,
the resulting radioactive
>> Hi. My name is Nadan.
So, I just want to give a conclusion.
Is technology good or bad?
What I want,
what I have seen, like
there are as Gandar explained
about the nuclear disasters,
I mean, the nuclear stuff.
There are goods.
There are bads.
You know, we need to take the goods,
we need to stop how much,
there are
bad things coming out of the technologies.
Not only that,
even in medical field,
like in previous couple
of days classes ago,
there was some
technology innovations
in medical where you know,
you can harvest human,
human body parts,
and that is,
that is really scary,
if they're harvesting
it for the black market.
So, if they are using properly,
and as per the guidelines
set up by the governments,
or the authorities,
which are taking good care of the laws,
it is always,
we should always make sure,
that how we are using
the technology today.
As far I know,
after this class,
these 14 sessions of,
13 sessions of the class,
what I've understood,
is like,
it's not,
we can't say this technology is bad,
this technology is good.
There are few situations where
so, initially we build the nuclear rods,
uranium rods,
where we can get the nuclear in
you get the most of our
if you are using for that,
to generate electricity,
or some sort of fuel
cells that should be good.
That would be useful for many people.
You can have some good stuff.
But if you are using for the atom bombs
killing thousands of people,
that is disaster, and catostrophe.
There are a number of technologies
where even internet can't tell
how many technologies
we have today in our,
There is not even a small,
There is not even an approximate count,
of how many technologies
do we have these days.
So how people are using the technologies,
like this man standing,
sitting on his branch,
sitting on a branch,
and cutting the branch,
on which he is standing.
So, It's okay.
He may die,
because that is his problem.
But what is the problem with this,
you are killing your family, your society,
what you are building as a future,
engineers, as we go
out, as we do our jobs.
You may end up in some,
creating some technologies,
where that should use,
that should be used for good,
not for the bad.
No, you can't kill your society,
and one or the other day,
your family,
or your grand-daughters,
they will see that effect.
So I have a small video here,
which is a very
