This one might be a no brainer if you've thought about it before. How many numbers can you count to in five seconds ?

 

For fast counters, out loud is about twenty seven seconds. In your head, it might be closer to thirty five.
 

Of course because higher numbers take longer to say, a fast counter can typically hit around 200 in sixty seconds. If you bring that up to an hour, it's somewhere around 1,200.
Doing the math without factoring in the amount of time it takes to say the higher numbers, it would take over 9,000 years to get to one trillion. If you're counting in your head, the results won't be much better.

If you count in your head for 24 hours straight, you will reach somewhere around 600,000. One whole year nonstop would give you 220 million, and if you counted for your entire life, you would only reach the billions, But you will never reach a "trillion".
 

Well, if you ever find yourself immortal and floating through space after the Earth is destroyed, now you know what you can do for fun.

How can you get something infinite out of nothing ?

"The point appeared in the circle
And was not;
But it was the dot
That the circle begot."

In geometry, a point has no dimension. It has no diameter, no depth. It does not really exist in space; it is really only an idea. Yet when you start to move it, its trail creates a line. Move it around another point, you create an arc. Continue describing that arc, and its end will eventually meet its beginning, and form an endless circle.

From nothing, something has taken form. From the point, a circle emerges. It is the existence of the circle that proves the existence of the point. The point is not-being; the circle is being.
===================================================

If p and q be any two unit vectors ... And (p+2q) and (q+2p) are the diagonals of a parallelogram ...the angle between p and q is 30 degrees, then AREA of Parallelogram is?

The desired area is = |(p+2q)x(q+2p)| /2

= |pxq+2pxp+2qxq+ 4qxp|/2
= |pxq+0+0-4pxq|/ 2
= (3/2)|pxq|
= (3/ 2)|p||q|*sin(30)
= (3/2)*1*1*(1/2)
= 3/4.

Which line is longest, AB or BC?

Who knows thisss?

142857 is a cyclic number, the numbers of which always appear in the same order but rotated around when multiplied by any number from 1 to 6. 

142857 * 2 = 285714 
142857 * 3 = 428571
142857 * 4 = 571428 
142857 * 5 = 714285 
142857 * 6 = 857142

Multiply 37,037 by any single number (1-9),

then multiply that number by 3.

Every digit in the answer will be the same as that first single number.

For example:
37,037*5=185,185.
185,185*3=555,555.

Pi 

1- Pi is the number of times a circle's diameter will fit around its circumference.

2- Most people would say that a circle has no corners, but it is more accurate to say that it has an infinite number of corners.

3- The first person to use the Greek letter Pi was Welshman William Jones in 1706.

4- The Pi memory champion is Hiroyoki Gotu, who memorised an amassing 42,000 digits.

5- Pi is the 16th letter of the Greek alphabet.

6- All the digits of Pi can never be fully known.

7- ”Pi Day” is celebrated on March 14 (which was chosen because it resembles 3.14). The official celebration begins at 1:59 p.m., to make an appropriate 3.14159 when combined with the date. Albert Einstein was born on Pi Day (3/14/1879) in Ulm Wurttemberg, Germany

8- You can easily memorize the value of Pie upto 10 digits,
π ~ 3.141592653
just learn this sentence :
"Can I have a large container of coffee? Thank you....."
(here alphabates in each word represent the respective digit.)

A little boy was doing his maths homework.
He said to himself, "Two plus five, the son of a b!tch is seven.

Three plus six, the son of a b!tch is nine..."
His mother heard what he was saying and gasped, "What are you doing?"

The little boy answered, "I'm doing my maths homework, Mom."
"And this is how your teacher taught you to do it?" the mother asked.
"Yes," he answered.

Infuriated, the mother asked the teacher the next day, "What are you teaching my son in maths?"

The teacher replied, "Right now, we are learning addition."
The mother asked, "And are you teaching them to say two plus two, the Son of a bitch is four?"

After the teacher stopped laughing, she answered,
.
.
.
.
"What I taught them was, two plus two, THE SUM OF WHICH, is four."
