Effect of Modi's foregien visits


Prime minister Mr. Narendra Modi has visited many countries since he took oath almost a year ago. Many of us criticizing him for his so many foregien trips including opponent parties. But believe me friends his foregien trips are quite beneficial for the country. Opponents are just misleading by saying his foregien trips are worthless. I will give you some statics given by a leading newspaper and you will be amazed.
Read carefully-

India received $19.78 billion foreign direct
investment (FDI) from 12 countries visited by Prime Minister
Narendra Modi in financial year 2014-15, Parliament was
informed today.
During the period, Indian companies invested $3.42 billion in
these countries which include Bhutan, Brazil, Nepal, Japan,
the US, Myanmar, Australia, Fiji, Seychelles, Mauritius, Sri
Lanka and Singapore.
The total outflow and inflow of foreign investment in general
for 2014-15 fiscal was $6.42 billion and $75.71 billion,
respectively, Commerce and Industry Minister Nirmala
Sitharaman said in a written reply to Rajya Sabha.
In 2014-15, FDI in India increased by 27 per cent to $30.93
billion."

So you can analyze now that his foreign trips are worthwhile and can boost our economy fastly.

Know Google's new CEO- An Indian



As Google's third CEO, Pichai is taking over a
company in flux. In a massive corporate
restructuring, Google has become a subsidiary of
Alphabet, a new company run by Google co-
founders Larry Page and Sergey Brin.
Pichai, 43, was born in Tamil Nadu, India. After
graduating college in India for metallurgical
engineering, he came to the United States to study
at Stanford University -- the alma mater of the
Google founders and so many other early Googlers.
Pichai got his start at Google in 2004, building the
now defunct Google toolbar. The toolbar allowed
Internet Explorer and Firefox customers to make
Google their default search engine .
In the next few years, he took over Chrome,
Google's Web browser. When he introduced Chrome
to the world in 2008, the world reacted with
puzzlement: How could it compete with Internet
Explorer and Firefox?
Yet Chrome eventually became the world's most
used Web browser. Chrome even became a
successful operating system for Chromebook
laptops, used mostly by schools.
Pichai eventually became vice president, then senior
vice president in 2013 when he added Android to his
growing portfolio.
Last year, he became Google's product chief,
overseeing virtually all Google software products
not named YouTube. He runs Google+, Google
Wallet, Android Pay and Google's Apps services for
businesses.


Pichai also runs the Google I/O developers
conference, where he serves as the public face of
Google for eager customers waiting to know what
the next versions of Android and Chrome will do. He
also shows off the company's biggest new products
and services, including kicking off this year's
massive Google Photos announcement.
Subdued and generally quiet, Pichai is admired at
Google not just for his obvious engineering talents
but also his general likability.
"Sundar has been saying the things I would have
said (and sometimes better!) for quite some time
now, and I've been tremendously enjoying our work
together," said Page in a blog post announcing the
move.
As CEO of Google, he gets one more feather in his
cap and adds a few more products to his now giant
kingdom -- search, ads, maps, apps, Android,
Chrome and YouTube will now all be under his
purview.

swami vivekananda thoughts

Swami Vivakanada's top 10 quotations that inspires you the most



1)Take up one idea. Make that one idea
your life - think of it, dream of it, live on
that idea. Let the brain, muscles, nerves,
every part of your body, be full of that
idea, and just leave every other idea
alone. This is the way to success.
2)We are what our thoughts have made us;
so take care about what you think.
Words are secondary. Thoughts live; they
travel far.
3)You have to grow from the inside out.
None can teach you, none can make you
spiritual. There is no other teacher but
your own soul.
4)The moment I have realized God sitting
in the temple of every human body, the
moment I stand in reverence before
every human being and see God in him -
that moment I am free from bondage,
everything that binds vanishes, and I am
free.



5)Arise! Awake! and stop not until the goal
is reached.
6)You cannot believe in God until you
believe in yourself.
7)Our duty is to encourage every one in his
struggle to live up to his own highest
idea, and strive at the same time to make
the ideal as near as possible to the
Truth.
8)The more we come out and do good to
others, the more our hearts will be
purified, and God will be in them.
9)The whole secret of existence is to have
no fear. Never fear what will become of
you, depend on no one. Only the moment
you reject all help are you freed.
10)Condemn none: if you can stretch out a
helping hand, do so. If you cannot, fold
your hands, bless your brothers, and let
them go their own way.

what is good education

when we heard the word education, a picture series runs on our mind in which we see schools, teachers, students or if if we are already done with our schooling then we thought of our school days. These whole things which I have described was part of our education. Education in all sections of this world defines by all these parameters schools+ teachers+ students.



 Apart from these many other things may be there but these three things most important and must be their to get education. Some of you may think why I have described schools as essential part of education as to get education students means you and teachers means anyone who teaches you is sufficient. I have described schools as important part of proper education because we must have a class room so our infant from his/her very beginning in schools can learn how to interact with others means he learns how to be social in schools, but without schools knowledge he can gain but not education as being social is part of good education.



 So now you can imagine that a good education just not to get knowledge of particular subject but good education teaches us to be practical, be social, be friendly to everyone and so on. Only this good education can make you excel in your life, getting only knowledge is not sufficient to live in this world.

Its not the responsibility of only schools or government to make you infant social its parents who teaches him or her to be practical to be social to be gentle to everyone. If someone is good in his academics but not gentle not social he will find hard to live on this earth because we human beings are somehow social animals.



So when you think good education think other parameter also apart from knowledge is to make your child social, gentle and practical.

Reservation in Education

Reservation in our education system , is considered to be a backbone to certain communities. These communities are Schedule Casts, Schedule tribe and OBC ( creamy and Non creamy). So why government is given these communities such special reservation in education as compared to general person.



it all start with untouchablity, means in past schedule casts were treated to be untouchable. They didn't have rights in society same as upper caste peoples. They worked for upper caste people, in overall they were badly treated at that time. Due to which trend started that a person who is of lower caste can't eat, live or even get education with upper caste people. As time passed they lower caste people were so harreshed that they were mentally and socially get neglected.
After Independence, because we live in Democratic country where everyone has right to live equally, it was realized that these lower castes peoples whose percentage was very less in all sectors as compared to upper caste peoples should be increased, so only we can talk about equality. The overall thought according to me was right because as a human being if you think whatever lower caste people faced during post independence was inhuman act. In starting Parliament implemented this for 10 years but after every 10 years it was increased and even now we have reservation in education system.
according to my view what I observed regarding reservation is that at starting the reservation rule was absolutely right because at that time lower caste people percentage in all sectors were so less. Still lots of areas are such where untouchability exists for which I totally support reservation. But what I observed regarding reservation system is that a person who needs it more is not getting this. Let me give you an simple example, a person from lower caste who don't have anything in his childhood achieved great success in his life with getting reservation in every field. According to me it is right if he gets reservation. But now think that his son or daughter giving any exam getting reservation is right or wrong. It is wrong because his son or daughter have everything now just because they are from lower caste they are getting reservation is wrong. Now a days what I observed is that maximum number of peoples whom are getting reservation don't require it. But some of areas in India have peoples , must have reservation which I support.
one thing I want to add here is that now reservation should not be given in name of caste. Because according to me lots of people just to get reservation in India make their false certificates though they have enough money but getting all facilities just because they are lower caste in papers. This I observed in my college time.



Another thing which I want to add in not to give reservation in name of caste is that, think of a poor student. His father don't have enough money so he can get proper education. Just because he is from general category he can't get any such reservation. It seems totally wrong. Though the concept of reservation was right but now I think amendments should be done. Reservation earlier during just after independence can be understood based on caste, but now after 6 decades still giving reservation just in name of caste didn't seem proper, reservation I totally support but it should be given due to financial conditions of one. Poor must get reservation because poor is poor we can't decide him in terms of his caste as upper caste poor or lower caste poor or Hindu poor or Muslim poor.
give your views also.

Education system in India

India is a country of around 1.25 billion peoples of which 65% population is young, means india is young nation. To progress we must focus on youths because they will decide future of the nation. Education is primary and most important criterion for better india as if everyone in younger generation will get proper education than only India will prospected.



In this direction from very first election till now government of India has done some great work. Presently around 990 billion rupee budjet is alloted for this. HRD ministry is responsible for higher education system as of primary education state government along with center is responsible.
At present 75% ( round figure) of population in India is educated. Let us now analyze thing rather than going to facts. I will took point by point analysis  but all regarding Government schools and colleges.

1) the very first thing to boost primary education government of India has already started Mid Day Meal scheme, so our children will get better health also.

2) books, dresses etc are free up to 8th standard.

3) the fee in government schools are so less and we compare this with private schools it is about 1/50 or more also. So government is taking less but giving more.

4) still we people don't choose government schools for our child. We are ready to pay 50 times fee even teacher who is teaching in private schools not even qualified any of the exam whereas all government teachers are well qualified.

 5) even what I observed that a government teacher prefer private schools for his infant. It simply shows that they don't have believe in their own system.

6) in reality government schools have very less number of students present there in most of the places.

7) let us now think of higher education. For graduation many options are present in India like engineering, doctor, law, science etc.



8) but what I observed is that Indian education system works only for a good degree.

9) when I say that "works only for good degree" it means we do graduation to get only degree not some knowledge or for skill development in us.

10) for this government is not responsible because they already have provide us all facilities but it is us that we want degree only not proper knowledge.

 11) like for example South Korea and India started building their education system in same year. We focused on Degree based preparation and they focused on skill development. you can analyze where they have reached in technology.

 I am not criticizing totally the education pattern but somehow to become world power we can't work with such education system. We must change it. When I say we it means Government+ we people of this great country.

INNER PEACE




When we heard this " inner peace", some positiveness comes automatically. In this busy and hectic life most of us are not happy; but we all wanted to be happy. So the question arises in our mind automatically; how to be happy. Is there any tool or machinary or government sceheme. The answer is NO. But let me tell you a screat, there is always a person who can make you happy and that special person ( or say great person) is YOU
.
you are the one who is key to make yourself happy. We all know happiness is the key of peaceful life and vice versa peaceful life leads to happy life.
when I say peace it means inner peace.



I met lots of people, they are earning enough money, they wanted something in past which they have acheived already but they are not happy with their life, still searching for inner peace.
during my undergraduate program I met a gentleman Aveshy Witkow, he was from Is real. He told me that he came India to get inner peace because He is not happy with his life. While returning I asked about what he got and he said he still not happy.
The question arises why he was not?

I think the answer is inner peace to get happy life cannot be achieved by travelling far. The place you have to visit, is your own hearth. Ask yourself what you want? If you do what your hearth says then you must be happy because now you are listening to yourself not others.

Effect of technology on education


In the words of "Nelson Mandela"- " education is the most powerful weapon which you can use

to change the world".



thinking of this deeply, when we thought changing the world by education, what does it mean?

Simply it means, education teach people to think critically, positively. So the world can change.

technology from some past decades is also changing; so is it right to say technology is changing

the world? Yes of course. Technology has changed the way we live, travel, and affect all of us

somehow. If this technology is changing the world and change in world can be done by

education we can think of that technology has changed the education.

 But as it said every coin has 2 sides, effect of technology on education also have 2 sides.

thinking of negative side, think of calculators. Though it makes calculation easy and fast, but

making our capability of thinking is decreasing. Games are also considered to be part of good

education, but when we say games it does it mean graphical games. No, it means physical

activities so we can be fit to be learn everything. Video games are attracting new generation

though they are colorful, interesting but they make us physically imperfect.



as it said noting has only bad in it. Technology has changed our education system a lot. Distance

learning, e- education, smart classes, computers are those examples where we see positive

impact of technology on education. And there is many more latest technologies in education

system now a days. Technology has made our education very fast and advanced, so thanks to

technology.

Line Follower Robot using Arduino

This line follower robot is basically designed to follow a black line on a white surface. Any way the same project can be used to follow the opposite configuration with appropriate changes in the software. The entire hardware of this simple line follower robot using arduino can be divided into three parts. The sensor, arduino board and the motor driver circuit. Lets have a look at the sensor first.

Sensor.

The sensor consists of two LED/LDR pairs with appropriate current limiting resistors. The resistance of an LDR is inversely proportional to the intensity of the light falling on it.  The circuit diagram of the sensor is shown in the figure below.
arduino line followerResistors R1 and R2 limits the current through the LEDs. Resistors R6, R8, R3,and R5 forms individual voltage divider networks in conjunction with the corresponding LDRs. When the sensor is correctly aligned, both LED/LDR pairs will over the white surface. In this condition sufficient amount of light gets reflected back to the LDRs and so their resistance will be low. So the voltage dropped across the LDR will be low. When the robot is drifted to  one side , the sensor in the opposite side falls over the black line and the intensity of light reflected back to the corresponding LDR  will be low. As a result the resistance of the LDR shoots up and the voltage dropped across it will be high. The voltages dropped across the right and left LDRs (nodes marked R and L in the above circuit)  are given as input to the analog input pins A4 and A3 of the Arduino board. Right and left sensor outputs observed while testing the above circuit is shown in the table below.
line follower robot using arduino

Arduino uno board.

The arduino board has to be programmed to keep the robot in correct path. This is done by reading the left and right sensor outputs and switching the left and right motors appropriately. Output of the right sensor is connected to the analog input A4 of the arduino and output of the left sensor is connected to the analog input A3 of the arduino. The voltage range that can be applied to a particular analog input of the arduino is 0 to 5V. This range can be converted into a digital value between 0 and 1023 using  analogRead () command.  For example if 3V is applied to A3,  the following code will return 3/(5/1023) which is equal to 613 in the variable leftValue.
int leftInput = A3;
int leftValue=0;
void loop ()
{
leftValue = analogRead (leftInput);
{
From the above table you can see that the voltage across a particular LDR will be 4.4V when it on white and 4.84V when it is on black. The digital equivalent of 4.4V will be 900 and that of 4.84V will be 990 as per the above scheme.  The median of these two values is 945 and it is set as the reference point for the program to check the orientation of the sensor module.
The program identifies the position of the sensor module by comparing the sensor readings with the reference point that is 945. If the reading of a particular sensor is greater than 945 the program can assume that the particular sensor is above black. If the reading of a particular sensor is less than 945 then it is assumed that the particular sensor is above white. If both sensor readings are less than 945 then it means both sensors are on white. If both sensor readings are above 945 it is assumed that both sensors are above black (the same thing happens if we lift the robot off the track). Based on the above four conditions, the program appropriately switches the left and right motors to keep the robot following the black line.

Motor driver.

The motor driver circuit is based on two NPN transistors Q1 and Q2. Each transistors are wired as a switch with a resistor at its base for limiting the base current. The motors are connected to the emitter terminal of the corresponding transistors. A 0.1uF capacitor is connected across each motor  for by-passing the voltage spikes. Back emf  and arcing of brushes are the main reason behind the voltage spikes. If these voltage spikes are not by-passed it may affect the Arduino side.   Circuit diagram of the motor driver is shown in the figure below.

Circuit diagram.

Full circuit diagram of the line follower robot  is shown in the figure below.
line-follower

Program.

int leftInput=A3;
int rightInput=A4;
int leftMotor=13;
int rightMotor=12;
int leftValue = 0;
int rightValue = 0;
void setup()
{
  pinMode (leftMotor, OUTPUT);
  pinMode (rightMotor, OUTPUT);
}
void loop()
{
  leftValue = analogRead (leftInput);
  rightValue= analogRead (rightInput);

 if
   ( leftValue < 945 && rightValue < 945)
   {
     digitalWrite (leftMotor, HIGH);
     digitalWrite (rightMotor, HIGH);
   }
   else
   {

     if
     ( leftValue > 945 && rightValue < 945)
    {
      digitalWrite (leftMotor, LOW);
      digitalWrite (rightMotor, HIGH);
    }
 else {
   if (leftValue < 945 && rightValue > 945)
   {
   digitalWrite (rightMotor, LOW);
   digitalWrite (leftMotor, HIGH);
   }
   else
   {
     if (leftValue > 945 && rightValue > 945)
     {digitalWrite (rightMotor, LOW);
       digitalWrite (leftMotor, LOW);
     }}
      }
    }}

Setting up the circuit.

  • First of all remember that each LED and LDR has its own characteristics.
  • Carefully measure the voltage across each LDRs in both scenarios (on white surface and black).
  • A lot of parameters like individual LDR/LED characteristics, ambient light, clearance between sensor and surface etc may affect the result.
  • Get in to your own reference point for the program. In my case it was 945 but you may get a different value.
  • Use a separate power supply unit for powering the motors. Anything above 100mA will be hard for the USB port.
  • The motors used here are 9V/30RPM DC bow motors. If such a configuration is not available, choose the closest one.
  • While soldering up the sensor module, the gap between the two LED/LDR pairs must be selected according to the width of the black line. In my case it was 2cm.
  • Clearance of the sensor from the ground was around 1cm in my case.
  • The sensor LEDs used were 4mm bright green LEDs.
  • The sensor LDRs used were general purpose LDRs.
