IDENTIFYING DIFFERENT NUMBERS



Different numbers

Natural numbers : The counting numbers like 1,2,3,4,5.. are called natural numbers.

Integers : All natural numbers, their negatives and 0 are called integers.

Whole numbers : All natural numbers and 0 are called whole numbers.

Rational numbers : The numbers which can be expressed in the form p/q,where p and q are integers and q not equal to 0, are called rational numbers.

Irrational numbers : Any real number which cannot be expressed in the form p/q, where p and q are integers and q not equal to 0, are called irrational numbers.

Real numbers : Both rational numbers and irrational numbers together are known are real numbers.

Absolute value of real number : ( Modulus ) The non negative value of a number without regarding its sign.

PRISMS


Prisms

They are 3- dimensional figures.

Different types of prisms

Rectangular prism.

Square prism.

Cylinder ( Circular Prism ).  

Cube etc.

Main points.

Sum of the areas of all faces excluding the base on top and bottom of the prism is the L.S.A. of a prism.

The Lateral Surface Area or L.S.A. of any prism is equal to the product of the base perimeter and its height.

L.S.A. =  Base perimeter * Height.

The Total surface area  is the sum of the areas of all the faces. T.S.A. of any prism is equal to the sum of the L.S.A and double the base area.

T.S.A. = L.S.A. + 2 * Base area.

Volume of a prism is the capacity of the prism that it can hold. Volume of any prism is equal to the product of the base area and its height.

Volume = Base area * Height. 

SEMICONDUCTORS


SEMICONDUCTORS : THEY ARE MATERIALS WHICH HAVE CONDUCTIVITY LYING BETWEEN THOSE OF AN INSULATOR AND A CONDUCTOR.

INTRINSIC (PURE) SEMICONDUCTORS -UNDOPED SEMICONDUCTOR,i-TYPE SEMICONDUCTOR.

EXTRINSIC (IMPURE) SEMICONDUCTORS- A SEMICONDUCTOR WHICH IS DOPED.

DOPING : THE EFFICIENCY OF SEMICONDUCTORS ARE IMPROVING IN TECHNOLOGY BY INTRODUCING A SMALL NO: OF SUITABLE REPLACEMENT ATOMS INTO THE SEMICONDUCTOR LATTICE. IT IS A PROCESS OF CONVERTING AN INTRINSIC SEMICONDUCTOR INTO AN EXTRINSIC SEMICONDUCTOR.THIS PROCESS IS KNOWN AS DOPING.

TYPES OF SEMICONDUCTORS

n-type SEMICONDUCTORS : NO: OF NEGATIVE CHARGE CARRIER IS LARGER THAN THE POSITIVE CHARGE CARRIER.
p-type SEMICONDUCTORS : NO OF POSITIVE CHARGE IS GREATER THAN NEGATIVE CHARGE CARRIER.
p-n junction type

SIMILAR TRIANGLES

Similarity

If two objects are similar, they would have the same shape and proportion.

Theorems to determine similarity.

If three angles of a triangle are equal to three angles of another triangle, then these triangles are similar and the sides opposite to equal angles are proportional.
If two angles of a triangle are equal to two angles of another triangle, then these triangles are similar.
If three sides of a triangle are proportional to three sides of another triangle, then these triangles are similar
If two sides of a triangle are proportional to two sides of another triangle and their including angles are equal then these triangles are similar.

Main points to remember. 

The line joining the midpoints of two sides of a triangle is parallel and half as long.
The centroid of a triangle divides the median into 2 : 1

ARROW AND THE SONG

The Arrow and the Song

I shot an arrow into the air,
It fell to earth, I knew not where;
For, so swiftly it flew, the sight
Could not follow it in its flight.

I breathed a song into the air,
It fell to earth, I knew not where;
For who has sight so keen and strong
That it can follow the flight of song?

Long, long afterward, in an oak
I found the arrow, still unbroken;
And the song, from beginning to end,
I found again in the heart of a friend.
 By Henry W. Longfellow.

DIFFERENT TYPES OF MUTATIONS


1.  DNA base substitution, insertion, and deletion
2. unequal crossing-over and related structural modifications of chromosomes
3. partial or complete gene inversion and duplication
4. irregular numbers of chromosomes

MUTATION



MUTATION

MUTATION IS THE PERMANENT CHANGE IN THE DNA SEQUENCE OF A GENE.
MUTATIONS MAY LEAD TO MISSING OR MALFORMED PROTEINS WHICH MAY LEAD TO DISEASES.MUTATIONS HAPPENS DURING CELL DIVISION WHEN THE DNA GETS DUPLICATED. A FEW TYPES OF MUTATIONS ARE BAD FOR US BUT SOME MUTATIONS ARE BENEFICIAL FOR US,THEY CAN CREATE GENETIC DIVERSITIES. CANCER USUALLY OCCURS DUE TO THE MULTIPLE MUTATIONS INSIDE A SINGLE CELL.

CAN WE TRAVEL IN THE SPEED OF LIGHT?




THE ANSWER WHICH IS AVAILABLE TODAY IS NO.SCIENTISTS BELIEVE THAT NOTHING CAN TRAVEL IN THE SPEED OF LIGHT. THEY SAY THIS BECAUSE THERE IS NO ENOUGH ENERGY IN THE WHOLE OF THE UNIVERSE TO MAKE EVEN A SMALLEST THING TO REACH SUCH A SPEED.

DAFFODILS BY WILLIAM WORDSWORTH



I wandered lonely as a cloud
That floats on high o'er vales and hills,
When all at once I saw a crowd,
A host, of golden daffodils;
Beside the lake, beneath the trees,
Fluttering and dancing in the breeze.

Continuous as the stars that shine
And twinkle on the milky way,
They stretched in never-ending line
Along the margin of a bay:
Ten thousand saw I at a glance,
Tossing their heads in sprightly dance.

The waves beside them danced; but they
Out-did the sparkling waves in glee:
A poet could not but be gay,
In such a jocund company:
I gazed--and gazed--but little thought
What wealth the show to me had brought:

For oft, when on my couch I lie
In vacant or in pensive mood,
They flash upon that inward eye
Which is the bliss of solitude;
And then my heart with pleasure fills,
And dances with the daffodils.
