Don't boys want to wear pink or Is that girl's dislike to see boys in pink?

Tell me one color boys don't wear? Pink. Isn't it.Let's do a little research to see what's the proper reason. I gathered fifteen boys and ten girls and asked them a few questions.
Questions


  1.  What is your favorite color?
  2.  Do you like too see men in Pink?
  3.  Do you like to see girls in pink?
  4.  Do you hate Pink?

Three-month falling from the top of Everest?

Last day my friend told me that there are places where you fall for three months from Everest. What's your thought on that. So I made this post to check out that "Myth". 

Data we will need

  • Everest's height = 8,848m ( m = meters) [From the top to the very bottom level]
  • If a man fell from that top, he'd fall due to the gravitational acceleration ( g.acceleration = g) 


Lets do the MATH


S = Ut + 1/2 at^2
S = distance fell

U = Initial speed/velocity , in this case it's zero. If some one gave a pull the falling would be even shorter ( So i Use zero as the initial speed.

a = acceleration. In our case it's the gravitational acceleration which equals to "g". We can use 10 as the value of "g"

t = Time it took for the falling. We do this little math to find out this time. 



S = Ut + 1/2 at^2
8,848 = 0*t + 1/21* 10^2                                             [^2 = power of two]
t = 42.06 s. 

[ I used some simple Maths here,  It is the equation you find in "Motion" of physics. ]
What? Yeah. It's quite unbelievable, but it just takes 42.06 seconds to fall from the top of the Top of the Everest.

Less than 1 minute. Interesting huh?

Man on the moon; did it really happen?

In 1961 after Russian’s successful attempt of sending a man to space left Americans behind the space race. So the  American’s wanted to prove themselves the best. So the president John F Kennedy proposed an amazing idea of sending man to Moon. After 8 years from the day of this proposal the Americans sent a man to the moon. Neil Armstrong was the first person ever to set the foot on the moon.

Bermuda Triangle: Mystery beyond the explanation of science?

Bermuda triangle is also known as the Devil’s triangle is a place where various kinds of mysterious things happened. Bermuda triangle is a place in the western part of the North Atlantic Ocean. Boundaries of this triangle cover Florida, the Bahamas and Bermuda. In this area there were many kinds of disappearances of aircrafts and surface vessels. The Flight 19 is a famous mysterious incident which happened in 1945. Flight 19 was a training flight with five TBM Avenger Bombers which went missing in the area of Bermuda triangle. This incident made various kinds of explanations to describe the possible reasons to these occurrences.

Explanations to these mysterious incidents.

Does the "Cloud cover" really help the Cricket ball to swing? (Biggest Cricket myth)


  • You don't want to be a Cricket fan to read this post. This is about the biggest Cricket myth ever. I'll explain what "Swing" is for non-Cricket fans. Faster bowlers usually balls at speeds of 120kmh -150 kmh. While they bowl they change the path of the ball, so the ball will not come in the same track. Some bowlers swing the ball in both the directions making it really difficult to the batsmen.

Coffee helps to study long hours. Myth or Fact?

Who doesn't want to study longer hours? We all may need. So what's the drug we use? None other than a hot Coffee which contains Caffeine. Caffeine is a bitter xanthine alkaloid and psychoactive stimulant which helps us to study a whole night. It's a fact. Not a myth.
