LOGICAL QUESTION

WEIGHING IN A HARDER WAY

You've got 27 coins, each of them is 10g, except for 1. The 1 different coin is 9g or 11g (heavier, or lighter by 1g). You should use balance scale that compares what's in the two pans. You can get the answer by just comparing groups of coins.
What is the minimum number weighings that can always guarantee to determine the different coin.

EINSTEIN'S BRAIN

Einstein's brain 

Einstein's brain was preserved after his death in 1955, but this fact was not revealed until 1986.

The brain of physicist Albert Einsteinhas been a subject of much research and speculation. It was removed within seven and a half hours of his death. The brain has attracted attention because of Einstein's reputation for being one of the foremost geniuses of the 20th century, and apparent regularities or irregularities in the brain have been used to support various ideas about correlations in neuroanatomy with general or mathematical intelligence. Scientific studies have suggested that regions involved in speech and language are smaller, while regions involved with numerical and spatial processing are larger. Other studies have suggested an increased number of glial cells in Einstein's brain.

When Einstein died in 1955, his body was cremated and his ashes scattered, as was his wish. However, before his body was cremated, pathologist Thomas Harvey at Princeton Hospital conducted an autopsy in which he removed Einstein's brain. Rather than putting the brain back in the body, Harvey decided to keep it, ostensibly for study. Harvey did not have permission to keep Einstein's brain, but days later, he convinced Einstein's son that it would help science. Shortly thereafter, Harvey was fired from his position at Princeton because he refused to give up Einstein's brain.

For the next four decades, Harvey kept Einstein's chopped-up brain (Harvey had it cut into over 200 pieces) in two mason jars with him as he moved around the country. Every once in a while, Harvey would slice off a piece and send it to a researcher. Finally, in 1998, Harvey returned Einstein's brain to the pathologist at Princeton Hospital.

INTER GALACTIC COLLISIONS

INTER GALACTIC COLLISIONS 

There are many things that we gonna miss in this universe. Just watch and enjoy things we could see.

This video from https://m.youtube.com/results?q=what+will+we+miss
really tells use the happens of our galaxy and inter galactic collisions that we will miss as it happens many  million years later.
Milky way galaxy on which we stand is going to collide to another galaxy in the outerspace which results in a super visual effects.

GENERAL RELATIVITY THEORY

General relativity is a theory of gravitation developed by Einstein in the years 1907–1915. The development of general relativity began with theequivalence principle, under which the states of accelerated motion and being at rest in a gravitational field (for example when standing on the surface of the Earth) are physically identical. The upshot of this is that free fall isinertial motion: an object in free fall is falling because that is how objects move when there is no force being exerted on them, instead of this being due to the force of gravity as is the case in classical mechanics. This is incompatible with classical mechanics and special relativity because in those theories inertially moving objects cannot accelerate with respect to each other, but objects in free fall do so. To resolve this difficulty Einstein first proposed that spacetime is curved. In 1915, he devised the Einstein field equations which relate the curvature of spacetime with the mass, energy, and momentum within it.

Some of the consequences of general relativity are:

• Clocks run slower in deeper gravitational wells. This is calledgravitational time dilation.
• Orbits precess in a way unexpected in Newton's theory of gravity. (This has been observed in the orbit of Mercuryand in binary pulsars).
• Rays of light bend in the presence of a gravitational field.
• Rotating masses "drag along" thespacetime around them; a phenomenon termed "frame-dragging".
• The universe is expanding, and the far parts of it are moving away from usfaster than the speed of light.

Technically, general relativity is a theory of gravitation whose defining feature is its use of the Einstein field equations. The solutions of the field equations aremetric tensors which define thetopology of the spacetime and how objects move inertially.

HOW IS IT POSSIBLE?

 

The day before yesterday, Chris was 7 years old. Next year, she'll turn 10. How is this possible?

Do you get it?  Please comment 

CAN YOU SOLVE IT??????

Some tricky problems

1. What is the value of x?
 
      x ^x^x^x^..........=10

2. There are 50 horses in a race track.
     Each time only 5 horses can race.
     After each race the first three fast
     horses are obtained. Minimum how
     many races will it take to obtain the
     first  three fast horses among the fifty.

3. What is the value of h???

         h^3+h^2+ h + 1 = 0

4. Find a

CRAZY BRAIN

Some interesting facts about brain.
1. Human brain has a unique capacity to calculate time. That is you can roughly tell how much time has passed after a particular incident.
2. Brain controls all your body parts.
    But if we think logically, brain is also a body part. So brain is the only organ of our body which controls itself.
3. Brain has capacity to read future, that's  why we sometimes feel that the occasion in if we are standing has already happened.
