How our brains different than a computer ?



Throughout history, people have compared the brain to different inventions. In the past, the brain has been said to be like a water clock and a telephone switchboard. These days, the favorite invention that the brain is compared to is a computer.

We all know that computers are better than people are at remembering things exactly and at performing complex numeric calculations with speed, But human brains still beat computers in a number of ways. 
 
For one, humans can integrate information from many different variables and stimuli, And they can learn by experience, observation and experimentation. Computers can't easily adapt to changing situations.

Computers can be programmed to perform outstandingly in a particular field, but they are not able to function in multiple disciplines. 

Our brain does a lot of things a computer does, like math, logic, analyzing input, creating output, and storing and retrieving information.
But brains do a lot of things that computers cannot. Our brains feel emotions, worry about the future, enjoy music and a good joke, taste the flavor of an apple, are self-aware, and fall in and out of love. 

Our brains are capable of analyzing new and unfamiliar situations in a way that computers can't.
We can learn from our past experiences and make inferences about the new situation.
We can experiment with different approaches until we find the best way to move forward. Computers aren't capable of doing that -- you have to tell a computer what to do.

Albert Einstein’s famous equation E=MC2 was not the result of a computer algorithm; it’s the result of a human brain.

Our brain has a kind of “built-in Google,” in which just a few cues (key words) are enough to cause a full memory to be retrieved.Of course, similar things can be done in computers, mostly by building massive indices of stored data, which then also need to be stored and searched through for the relevant information.
 
Another difference is that the human brain has an estimated storage capacity of 2.5 petabytes of information which you can’t find in a supercomputer also.

At the end, the idea to build this type of machine which can perform similar to our brain comes in a human mind.  
If we want to build biological models of the brain than we have to include some of 225 million billion interactions between cell types, neurotransmitters, neuromodulators and axonal branches,  which is not so easy, Because The human brain is incredibly complex. We still don't have a full understanding of how the brain works. Without this understanding, it's challenging to create a meaningful simulation of the brain.

Home Sweet Home

Home is the place where we are born and live. It is the sweetest place in the world. When we sense danger elsewhere we find safety in our home. When there is joy, we share it with other members of our home. Everybody loves home. For this reason are English poet has written:
"Home, home, sweet home,
There is no place like home."
Every person has a place which he treats differently than any other, the place where he feels more comfortable than anywhere else. It is not exactly the place where the person lives – it may be some house or flat from the past, for example, the one he or she lived during childhood in. Nothing is sweeter than home. As what they say it’s a place where you can find the true meaning of happiness, safety and peace. 
A home wouldn’t be considered a home without the presence of a complete, happy family. Our house, I consider it as a home where I truly belong. Since our home house has a portrait of a happy family I consider it as my “Home, sweet home.” Though we’re not complete anymore but still we are trying to fill in the emptiness we sometimes feel due to the absence of our father. Our home is full of memories which are really unforgotten and are to be cherished. That is the reason why I don’t want to leave our house. 
Everytime my brother and sister go to Cebu to continue their studies, I feel sad because the three of us, my Mama, my brother and I, myself are the only people left at home. It seems like again the house is filled with another emptiness just like we felt when my Papa died I know the two of them will come back after their classes, but it seems like I don’t want them to leave because we need them to make our home happier. As what they say, “The more, the merrier.” A happy home is what I really want. 
Our house is the place where all of the dramas, happiness and everything happens. That is why I won’t exchange it to other big houses, palace or even mansions because our home is a unique and perfect house for me despite the incompleteness of its physical appearance. I guess it’s not really necessary to have a beautiful house as long as you and your family are happy and complete. So if I were to decide, nothing can replace our house.

Friendship...













"every person is a new door to a different world"


"each friend represent a world in us, a world possibly not born until they arrive and it is only by this meeting that a new world is born"

"friends are the most important ingredient in the recipe of life"

"a friend is someone who knows the song of your heart, and can sing it back to you when you have forgotten the words"

"a real friend is one who stay with you when the rest of the world walks out"

"true friendship is like second health, the value of it's seldom known until it be lost"

"one of the most beautiful quality of friendship is to understand and understood"

"a single rose can be your garden, a single friend can be your world"

...You Will Always Be My Friend...

when does life begins ?

The question, "when does life begins?", often arises in our mind. To becomes quite complicated to find an answer and many times we end up having these arguments in our mind like “does it happen when we take birth or at the time when we start recognising our surrounding world.”

If we say that life begins when we take the birth, then why are we unable to remember the memories when we are only 1 year old.


Some says that life begins at conception, and some philosophers say that it begins where fear ends and when our comfort zone ends.

Some says that it begins when we are able to express our feelings to someone, and when we are able to understand someone's feelings, thoughts and meanings behind things around us.

There is no particular answer for this question, but from my point of view-"life begins when we start enjoying our life without any limits and without any fear in our heart".

A Book with the title “When life begins?” by Abu Yahya, gives an encouraging view on these thoughts and I think it should on the “must read” books list!
