Dear Sir,

Sir! When I was listening to your lecture , I was wondering if every lecturer would take class very interestingly like you, then everybody would be very dedicated towards studies.

Everyone would enjoy being in class, regretting time.
Education would be fun.

But, after the lecture I realized that it is in the student whether to take it in a positive way or negative.It is we who has to change a lot and there is nothing to be changed from the lecturer side.

This is the major thing I have learned and I am going to change. From now on EDUCATION IS FUN for me..............................

And few more things I have learned are

  • Every subject is interlinked and we don't realize it.
  • Studying Nature is nothing but Technology. Not only the Nanotechnology from mosquito but much more.
  • Drinking lots of water give us less or no diseases.
  • Boiled water just quenches our thirst.
  • Our brain is more brilliant than us. As we do somethings without any reason like rubbing our forehead while thinking or in tension.
  • Nervousness can be reduced by drinking water.
  • Learning Physics makes us think practically. And beyond physics is Philosophy.
  • Nothing is impossible unless we think we can't make it.
  • Our attitude is depends on what we eat.
  • Concentration comes with interest and interest can be created by ourselves.
  • Good student always writes down the matter which he/she wants to remember.
  • Our desires can be achieved by doing them by heart, not by brain.
  • Heart is throughout our body which we don't realize.
  • And the most important thing is Education is Fun.
Sir!There is one thing I would like to tell.

When I said that when God gives me a wish I said that whatever I do I should excel in that. And u reacted so quickly and asked when I would be sleeping would I want to excel in sleeping. I was wondering how much time does it take for me to be like that.

And one thing I would like to ask you is "You said u were an astrologer, a physicist, a philosopher, a psychiatrist, and you even studied law ". How is it possible for a man to all of these at the same time????

Thank you Sir for letting me in even if I was late..And sorry for the late to send this mail.

I wish I could attend more seminars or lectures of you Sir.....And I really enjoyed every second of it.



-Today sir we learnt about all the subjects are inter-related to each
other.All the subjects should be given equal importance because they
will be use to us in some or other means.
-We also learnt about nanotechnology which is been used in different fields.
-First in 2005 microbiology was famous but now with the growth in
nanotechnology we are referring it for most nanosized particles.
-We learnt that whatever we do we should do with interest and eagerness.
-We learnt that mosquito bite is not harmful when mosquito sits on us
we don't get distracted by the way that it is biting us but when we
see we get panic. But when mosquito sucks blood from our body after
sucking blood it gives an anti anaesthesia but when we hit it the
syringe of the mosquito goes into our body due to which we get
-We also learnt that some part of knowledge is thought by the faculty
some, some is should be learnt by the student and some should be
learnt by group discussions preparing question papers and asking our
friend to solve it and then evaluating it.
-If a person want to get interest in a subject he or she should first
see the topic in the text book and should close the book for an hour
or so and after some time we should write what we know about the
particular topic without referring .By doing this we know what is
lacking in us which increases an eagerness to read that particular
-We also discussed about EEG(electroencephalogram) which is used for
testing and recording the electrical activity of brain.

what is nanotechnology?
Nanotechnology deals with nanosized particles and devices.
Nanoscale uses "nanometer" as the basic unit of measurement and it
represents a billionth of a meter or one billionth of a part.
One-nm is about 3 to 5 atoms wide.This is very tiny when compared
normal sizes day to day encounter.
for example this is 1/1000th the width of human hair.
Any physical substance or device with structural dimensions below 100
nm is called nanomaterial or nano-device.
Nanotechnogy is dependent on the technolgy that involves fabrication
of material,devices and systems through direct control of matter at
nanometer length scale or less than 100 nm.
Nanoparticles can be defined as building blocks of nanomaterials and
Nanoparticles include
nanotubes,nanofibers,fullerenes,dendrimers,nanowires and may be made
of ceramics,metal,non-metal,metal oxide,organic or inorganic.
At this small scale level, the physical, chemical and biological
properties of materials differ significantly from the fundamental
properties at bulk level.
Nanomaterial can be physically and chemically manipulated to alter the
properties, and these properties can be measured using nanoscale
sensors and gages.
Nanoscience is divide into two fields:-
Nanotools are required for manipulation of matter at nanoscale or atomic level.
Certain devices which manipulate matter at atomic or molecular level
are scanning-probe microscopes, atomic force microscopes, atomic layer
deposition devices and nanolitography tools.
Nanolithography means creation of nanoscale struture by etching or printing.
Nanotools comprises of fabrication techniques, analysis of metrology
instruments, software for nanotechnology research and development.
Softwares are utilized in nanolithography, 3-D printing, nanofluidics
and chemical vapour deposition.
Nanoparticles and Nanomaterials.


Respected sir,

Sub: A Document on guest lecture given by Dr. T P Sasikumar sir

Ref: Guest lecture given by Dr. T P Sasikumar sir at AEC, Bhongir, Nalgonda dist. On


My name is pavankumar sir. I am studying mechanical engineering first year

at aurora engineering college, Bhongir. Today I was very much thrilled with your lecture sir.

This gave me sufficient guidance to proceed further. As you asked us to prepare a

Document on today’s lecture I am going to repeat some points which attracted me.

Ø Learn the subject with interest and enjoyment that means with heart and

not by brain.

Ø Every person must know the importance and application of the particular


Ø You also interlinked and proved why physics is not different from chemistry by taking the example of 2 metals and by explaining the different types of bonds involved between them.

Ø Atom size calculation is explained by taking the example of the thickness of

Paper-such as by taking and calculating the thickness of 100papers or sheets and dividing with 100.

Ø To make the class interesting we should read the topics which are going to be

discussed the next day by the faculty.

Ø ¼th of knowledge will be given by faculty,1/4th should me learnt by students and

remaining portion can be gained by interacting with our classmates

Ø we must interact with any of our classmate and ask him to prepare on a particular topic.

Ask him to prepare a question paper on the topic and try to solve the paper which was prepared by him and try to give a question paper to him which was prepared by you.

Ø We also learnt how geography, geophysics are related to physics.

Ø We also learnt how electricity flows in the circuit-such as an excited state of electron is called electricity and it flows only through the peripherals and not through the centre of the circuit.

Ø If a person want to get interest in a subject he or she should first see the topic in the text book and should close the book for a while and after some time we should write what we know about the particular topic without referring .Then we can find the unknown part and thereby an anxiety grows which leads to an interest towards the subject.

Ø If a person wants to be a good student firstly he or she should note the important points in the class and if we have any doubts we should discuss with the classmates or search on the internet until we get the right and clear picture about the doubt.

Ø We have to prepare notes which make our conceptual study easy.

Ø We also discussed and learnt about nanotechnology by taking an example of mosquito-in which we have learnt about how a crunchy biscuit turns to soft when a mosquito sits on it

Ø Our brain knows about us .so “your brain knows you very well” and our brain is too intelligent than us.

Ø We also discussed why nanotechnology is used widely than micro technology by taking example of atom-such as nanotechnology can study by magnify an atom up to 10 to the power 9 where as micro technology can be explained up to 10 to the power of 6.

Ø At last after having awonderful lecture we concluded with a small remembering game.

v Last but not least we also learnt that “we should not waste time ,we should invest time”

Thanking you sir,

Yours sincerely,



Good evening sir, we are very much inspired by the way you have motivated us today in session.

thanks to you by which we have learnt many things like

1.How different subjects are related to each other.

2.Human behavior's.

3.How to cool some one's anger.

4.How to make morning of a day thrilling (though funny but true...!).

5.Why people are different in their physical appearance in different places.

6.Good students behavior.

7.Concentration and interest.

8.Importance of MANAS over BUDDHI.

9.Positive thinking and attitude.

10.Learning and sharing.

i hope we have further session like today's

thank you

  1. the awesome comparision said be Sasikumar sir is when he comparied the manas with a software
    i.e "manas is like a software ,can't be seen but only work's"..........
    i realied liked the comparision

  2. sri i have learned a lot from your seminar and your videos,blogs,etc.By this i came to know learning is fun. i wish i could attend more seminar's of you sir.
