THINK BEYOND

Everything in this world which exists exists with a reason. When we are born to this world we have a reason to be born. Hence anything we see must have a reason. And those who think beyond, different, are those who think odds. 

If you have ever heard that when refraction occurs the speed of light changes. But have you ever wondered from where does the light get the energy to alter its speed? If you want to know why please proceed with the reading.           

First of all I would like to remove a misconception of people treating a photon as a particle. A photon is simply a unit of energy which makes up light as light is also a form of energy. So when light enters a different medium the photons interact with the electrons of the material and get the electrons excited. To explain in simple words we could say that the electrons eat up the photons and afterwards when the electrons loose energy they loose it in the form creating and giving out new photons. So the energy supplied to light to alter its speed is given by electrons when they give out new photons but the basic properties of the new photons are the same as that of any other photon.

Now analyzing a bit more we note that the photons which enter the medium are not the same which leave it. In simple words you have a 1 liter bucket full of water and you add more 1 liter of water so would the water which splashes out is the same which was in the bucket.

                                               HOW IS MEMORY STORED IN CHIPS???

We all use chips and memory cards in our devices but what is it that makes that large amount of data to remain stored in those chips.

So, firstly I would like to clear a common misconception of people that data is stored like its written everywhere that it is stored in the form of a binary code 0, 1. But actually it’s not that data flows in the form printed like 010 00011000 the numbers 0 and 1 refer to low and high voltage respectively. The voltage which flows through devices that is what is named as 0 and 1 OFF and ON respectively.

Now, the chips or memory cards that we use have a floating gate transistor inside them. I would not get complicated just explain in simple words. So when this chip is connected to anything it receives electric current which flows in the form of low and high voltage when this current flows through the floating gate the electrons are forced into it and then are trapped inside the gate itself with help of an insulator.

Now some might question that if the electrons can’t get out how do they enter in the first place? The floating gate system has something you could call a semi –conductor so when current flows it has that much potential that it can force its way in through the semi-conductor but when the current is stopped the current which has entered already in doesn’t have enough force to come back hence it gets trapped in.

The floating gate has a drain system too which when connected to let’s say a computer device; it again gets charge or current flowing through it. So through the drain system the stored memory gets the charge to flow out and gives output.

Now another question may raise that if all the stored memory gets drained through the chip into the device how does it again get in?

Well there is a row of silicon through the way which gets empty when the charge drains out; then there comes an amplifier which absorbs the current flowing through the device and again stores it in. Since it’s all about low and high voltage there isn’t a question about if the same data gets in.

I have tried to explain it as simple as possible. If it was beneficial please leave a comment.
