hey, friends, here are some info. , which may be very useful ,in our daily studies.....

please have a look.....

its quite interesting.....................

Studying is an ongoing process and cannot be left until the night before an exam to be effective.

REVIEW: means to view or look at it again.
STUDY: means to think about the work until you understand it and can put it in your own words.

1. Studying is a daily process.
2. Plan your work. Divide the subject to be covered by the test into sections according to the number of days before the test for review.
3. Make a study schedule and check it off as you go.
4. Set a goal to improve your marks.
5. Study alone
6. Memorize by learning. Make sure you understand what you read. If you cannot clearly express the ideas in the note in your own words, you don't really understand it yet!

METHODS OF STUDYING

1. Three R's of studying:

- Read many times.
- Recite in your own words.
- Review often.

2. Memorize by learning

Read a section over until it is thoroughly understood. Read aloud with expression. Emphasize difficult points out loud. If you cannot clearly express the ideas in your own words you do not know them yet.

3. Test yourself

Make up different types of tests:
(a) True/False
(b) Multiple Choice
(c) Fill in the Blanks
(d) Essay Questions
(e) Numerical Response

4. If you have access to a tape recorder, tape your answers to your "test" questions. Listen to yourself and check your answers. if you found something difficult or you missed part of the answer, try again and again until you have the flill answer in your own words.

5. Note the main ideas and organize the details and examples under these. Then make up your own test questions and answer them later.

FIND THE METHOD THAT SUITS YOU BEST. USE IT. IMPROVE IT. "OVERLEARNING" GIVES YOU CONFIDENCE TO FACE A TEST.

QUICK TIPS FOR IMPROVING MEMORY

These Memory Boosters are powerful tools - pick one to practice each week to remember important content. -

1. Connect what you want to remember to a strong emotion through a moving story, song, or activity.

2. Personalize it by using your friends names and things you can relate to from your home and neighborhood.

3. Act it out as a skit or role play in a way to make it fun.

4. Present and review it in all of your senses: sight, sound, touch, taste, and smell.

5. Embed it in a real-life application that you can relate to and value.

6. Make it important to know.

7. Use distributed exposure - repeat it within 10 minutes, then again in 30 minutes, repeat it the next day, then in two days, then five, and so on.

8. Develop concrete connections and reminders.

9. Summarize it in words or mind maps.

10. Draw a picture that represents it.

11. Use acronyms.

12. Use Memory Chunking- no more than seven things to remember in any category.

13. Put it on a colorful, easily-seen poster and display it above eye height on the left side of your bed.

MNEMONIC DEVICES

Mnemonic strategies are memory aids that provide a systematic approach for organizing and remembering facts that have no apparent link or connection of their own. Mnemonics provide the tools necessary to memorize and recall almost any information.

1. Acronyms -

use the first letter of each word in a sentence to represent the first letter of the word/list you wish to memorize.

HOMES
(To learn the names of the Great Lakes)
ROY G BIV
(To remember the colors of the rainbow)

2. Poems, Rhymes, Rhythms -

use a familiar tune, substitute information to be learned: details, sequencing.

In 1492 Columbus sailed the ocean blue.

3. Chunking group bits of information together -

phone numbers

4. Picture -

use a picture to help you recall information

5. Name -

associate the name of someone to a particular concept / phrase / idea you want to remember

COMPLETING A CONCEPT MAP

1. Choose the Concept to be Mapped

2. Identify the objectives that need to be met

3. Collect materials that can be used to supply information Including:
- Textbook, Notebook, Lab Manual
- Other Textbooks (Grade 9 ,Grade 10 or Grade 11)
- Projects and Tests

4. Review the material that is related to the concept you are mapping

5. Summarize the general areas that need to be covered

6. Write these general points as headings

7. Identify the key points under each heading

8. Record the page or reference where this can be found Transfer this chart onto the Concept Map Handout (revise format if necessary)

9. Present your Concept Map to others in your study group

10. Revise your Concept Map based on your study group's feedback

11. Provide members of your group with a copy of your revised Concept Map

12. Go through your tests to find questions related to your concept

13. Cut and paste these on the back of your Concept Map

14. As you read over each concept, refer to the questions to see if you can answer them (without the answer), then check to see if you are right.

15. Try to create another question different from the ones you1ve worked on Test your group, using a combination of your question and past test questions when you are finished a particular unit.

16. Put all of your concept Maps, relating to the same Unit, together for future reference.

Last but not the least, studying in group and sharing concepts and other info. are always beneficial, it not only clears doubt but it also makes one feel much more confident.

As we,have been provided , such a great platform,by the name of GoIIT for sharing,thinking and learning.

SO, PLEASE THINK OVER IT , ITS A TRIED AND TESTED METHOD............

KEEP SMILING..................

ok answer this...

can you break this riddle,just try it................

i was always good in english and social science.......then an 992091 14 inspired me to
get out there and play the game he played...he told me...he topped in the game in 2006(the year he played it)............but..........

so...........

i joined the game.....................called 92020 1055...i enjoyed it....
i got addicted to it...but my parents were worried.......so...they talked to the game's psychatrists..at ...a special place........

questions........

1. what was the game i,got addicted to??
2.name the person , whom i talked to??
3.what was the special place called??
4.what is the significance of the number 9920??

try it....

hint:not many know this story.....

keep smiling.......................

and yes....
got the second one as well..........

its the silence.....

its fragile,can be easily broken as well as if even you speak out its name you brek it...
eg.
in libraries they say...
keep silence(its not easy to)
so even if you try to...but your teacher hears the rumble of his empty ,food demanding stomach...he speaks up saying ....keep silence...but the point is he himself broke the silence in the library...

poor teacher...is..he to be blamed or his empty , fat tummy

keep smiling.................

for the first one...
as the saying goes........
"an apple a day keeps doctor away...so,santa gives her an apple each day, so that banta always keep away from his girl...

keep smiling..

great work ,you got fused bulb.(samajh me aya..)

keep smiling.

oh ,i didn't see the expert's comments on it....though i myself wouldn't reccomend any one to go and waste too much time for it............
but yet just ,in case, you have some time...there's no harm at least thinking over it.......

the Goldbach's Conjecture problem seems to be simple, yet its thougthful...and solutions can be caugth to be incorrect at several scenarios...and thats what makes it a great historical unsolved puzzle.....as,at first look everybody..will think himself/herself to be able to solve this.........but,at this stage....you may get stuck..and sometime contradict even yourself.....

but, yet mark my words...it being unsolved for years doesn't mean that one cannot try to at least think over it ,provided make sure you are doing it just for the fact that you love mathematics..................

trying is no harm...i would suggest.if you find it quite interesting think over the problem again & again...but don't get addicted to the single problem...
and who knows .....wonders do happen..and it may be in you...
but, yes...as elders say...love it but don't get addicted to it.

think a bit.. solve the way you think it to be right ,give it a try atleast,as each question deserves it ...

only because its the...Goldbach's Conjecture, it doesn't mean you move away from it...it deserves a look atleast....
and as experts have said , yes just concentrate on getting into IIT, he is true to his words ,but its no harm applying a bit of brain to these kind of questions...you've nothing to loose..just use your brain..and who knows it may prove fruitful ,even if you aren't able to solve it.....

but...yes, i again say............if you love maths get to it, use your head..but never get deviated from your track...........

REMEMBER --------NO QUESTION IS UNSOLVABLE...THOUGH IT TAKES TIME MOST OF THE TIME....
so, in spare time...you can give it an honest try , it will only enhance yourthinking nothing else...

Wave Phenomena
Sound waves are longitudinal and mechanical.
Light slows down, bends toward the normal and has a shorter wavelength when it enters a higher (n) value medium.
All angles in wave theory problems are measured to the normal.
Blue light has more energy. A shorter wavelength and a higher frequency than red light (remember- ROYGBIV).
The electromagnetic spectrum (radio, infrared, visible. Ultraviolet x-ray and gamma) are listed lowest energy to highest.
A prism produces a rainbow from white light by dispersion (red bends the least because it slows the least).
Light wave are transverse (they can be polarized).
The speed of all types of electromagnetic waves is 3.0 x 10⁸ m/sec in a vacuum.
The amplitude of a sound wave determines its energy.
Constructive interference occurs when two waves are zero (0) degrees out of phase or a whole number of wavelengths (360 degrees.) out of phase.
At the critical angle a wave will be refracted to 90 degrees.
According to the Doppler effect a wave source moving toward you will generate waves with a shorter wavelength and higher frequency.
Double slit diffraction works because of diffraction and interference.
Single slit diffraction produces a much wider central maximum than double slit.
Diffuse reflection occurs from dull surfaces while regular reflection occurs from mirror type surfaces.
As the frequency of a wave increases its energy increases and its wavelength decreases.
Transverse wave particles vibrate back and forth perpendicular to the wave direction.
Wave behavior is proven by diffraction, interference and the polarization of light.
Shorter waves with higher frequencies have shorter periods.
Radiowaves are electromagnetic and travel at the speed of light (c).
Monochromatic light has one frequency.
Coherent light waves are all in phase.

Geometric Optics
Real images are always inverted.
Virtual images are always upright.
Diverging lens (concave) produce only small virtual images.
Light rays bend away from the normal as they gain speed and a longer wavelength by entering a slower (n) medium {frequency remains constant}.
The focal length of a converging lens (convex) is shorter with a higher (n) value lens or if blue light replaces red.

Modern Physics
The particle behavior of light is proven by the photoelectric effect.
A photon is a particle of light {wave packet}.
Large objects have very short wavelengths when moving and thus can not be observed behaving as a wave. (DeBroglie Waves)
All electromagnetic waves originate from accelerating charged particles.
The frequency of a light wave determines its energy (E = hf).
The lowest energy state of a atom is called the ground state.
Increasing light frequency increases the kinetic energy of the emitted photo-electrons.
As the threshold frequency increase for a photo-cell (photo emissive material) the work function also increases.
Increasing light intensity increases the number of emitted photo-electrons but not their KE.

Internal Energy
Internal energy is the sum of temperature (ke) and phase (pe) conditions.
Steam and liquid water molecules at 100 degrees have equal kinetic energies.
Degrees Kelvin (absolute temp.) Is equal to zero (0) degrees Celsius.
Temperature measures the average kinetic energy of the molecules.
Phase changes are due to potential energy changes.
Internal energy always flows from an object at higher temperature to one of lower temperature.

Nuclear Physics
Alpha particles are the same as helium nuclei and have the symbol .
The atomic number is equal to the number of protons (2 for alpha)
Deuterium () is an isotope of hydrogen ()
The number of nucleons is equal to protons + neutrons (4 for alpha)
Only charged particles can be accelerated in a particle accelerator such as a cyclotron or Van Der Graaf generator.
Natural radiation is alpha (), beta () and gamma (high energy x-rays)
A loss of a beta particle results in an increase in atomic number.
All nuclei weigh less than their parts. This mass defect is converted into binding energy. (E=mc²)
Isotopes have different neutron numbers and atomic masses but the same number of protons (atomic numbers).
Geiger counters, photographic plates, cloud and bubble chambers are all used to detect or observe radiation.
Rutherford discovered the positive nucleus using his famous gold-foil experiment.
Fusion requires that hydrogen be combined to make helium.
Fission requires that a neutron causes uranium to be split into middle size atoms and produce extra neutrons.
Radioactive half-lives can not be changed by heat or pressure.
One AMU of mass is equal to 931 meV of energy (E = mc²).

General
The most important formulas in the physics regents are:
Physics is fun. (Honest!)

Mechanics

Weight (force of gravity) decreases as you move away from the earth by distance squared.
Mass and inertia are the same thing.
Constant velocity and zero velocity means the net force is zero and acceleration is zero.
Weight (in newtons) is mass x acceleration (w = mg). Mass is not weight!
Velocity, displacement [s], momentum, force and acceleration are vectors.
Speed, distance [d], time, and energy (joules) are scalar quantities.
The slope of the velocity-time graph is acceleration.
At zero (0) degrees two vectors have a resultant equal to their sum. At 180 degrees two vectors have a resultant equal to their difference. From the difference to the sum is the total range of possible resultants.
Centripetal force and centripetal acceleration vectors are toward the center of the circle- while the velocity vector is tangent to the circle.
An unbalanced force (object not in equilibrium) must produce acceleration.
The slope of the distance-tine graph is velocity.
The equilibrant force is equal in magnitude but opposite in direction to the resultant vector.
Momentum is conserved in all collision systems.
Magnitude is a term use to state how large a vector quantity is.

Energy
Mechanical energy is the sum of the potential and kinetic energy.
Units: a = [m/sec²], F = [kg?m/sec²] (newton), work = pe= ke = [kg?m^²/sec²] (joule)
An ev is an energy unit equal to 1.6 x 10^-19 joules
Gravitational potential energy increases as height increases.
Kinetic energy changes only if velocity changes.
Mechanical energy (pe + ke) does not change for a free falling mass or a swinging pendulum. (when ignoring air friction)
The units for power are [joules/sec] or the rate of change of energy.

Electricity
A coulomb is charge, an amp is current [coulomb/sec] and a volt is potential difference [joule/coulomb].
Short fat cold wires make the best conductors.
Electrons and protons have equal amounts of charge (1.6 x 10^-19 coulombs each).
Adding a resistor in parallel decreases the total resistance of a circuit.
Adding a resistor in series increases the total resistance of a circuit.
All resistors in series have equal current (I).
All resistors in parallel have equal voltage (V).
If two charged spheres touch each other add the charges and divide by two to find the final charge on each sphere.
Insulators contain no free electrons.
Ionized gases conduct electric current using positive ions, negative ions and electrons.
Electric fields all point in the direction of the force on a positive test charge.
Electric fields between two parallel plates are uniform in strength except at the edges.
Millikan determined the charge on a single electron using his famous oil-drop experiment.
All charge changes result from the movement of electrons not protons (an object becomes positive by losing electrons)

Magnetism
The direction of a magnetic field is defined by the direction a compass needle points.
Magnetic fields point from the north to the south outside the magnet and south to north inside the magnet.
Magnetic flux is measured in webers.
Left hands are for negative charges and right hands are for positive charges.
The first hand rule deals with the B-field around a current bearing wire, the third hand rule looks at the force on charges moving in a B-field, and the second hand rule is redundant.
Solenoids are stronger with more current or more wire turns or adding a soft iron core.

we know one thing for sure...........2 is the only even no.

For prime numbers a,b,c

. . . . . a - b = (a + c) - (b + c) . . . . . even integer . . . . . . . . . . (1)

and thus, generally,

. . . . . a - b = 2k . . . . . . . . . . . . . k = integer . . . . . . . . .. . . (2)

and since a + b is an even number

. . . . . a + b = 2n . . . . . . . . . . . . n = integer>2 . . . . . . . . . . . . . (3)

Now, using (2) and (3) results in

. . . . . a = n + k . . . and . . . b = n - k . . . n>k . . . . . . . . . . . . . (4)

I can prove Goldbach's Conjecture, with reference to equations (2) ,(3)&(4).this proof of mine is just a simple 'by contradiction proof'-----suppose that not every sum of two primes a and b is an even number 2n>4(but this isn't possible as...2& 4 both are multiples of 2). However, since the number of twin primes is unlimited, their sum is an even number 2n unlimited and every sum of primes is an even number.

its quite, as simple as that ....

BUT, remember.....many times...the mathematical proffesors may also find flaws in what one persumes to be perfectly correct........
they may call it a" not universally accepted solution"...so at this stage this is the most we can do.......

keep smiling............

well one more unique solution.....
1! + 2! + 3 - 4 + 5 + 6 + 78 + 9 = 100.

keep smiling.
