the differences between the dream and the real
- Logic
- Look real but impossible to do because we know the rule of reality
- The conscious still behind your head
- Non logic thing happen
- No control
- Everything you know seem really blurred
- Dream first but after you awake it actually happen in real life
- Identify thing
- Remember thing
How do I know the difference
between the dream and the real ?
REALITY
DREAM
PRECOGNITION DREAM
1.DO YOU AGREE THAT
DREAM SOMETIMES GIVE US A MESSAGE ABOUT SOMEONE THOUGHT
2.WE CANT CREATE
THE THEME OF OUR DREAM- unlike of the world of reality . Imagine now you have
a pen and letter , write the story, our conscious mind create the story you
want to write.
3.HOW DO WE KNOW WE
ARE DREAMING OR NOT WHILE DREAMING
DREAM ARE A STATE
WHERE ALL REALITY IS NOT ACCEPTED (then you are knowing that you are dreaming)
ask yourself.
4.WHAT WE CAN DO IN
DREAM WHEN YOU KNOW YOU ARE DREAMING
-take control your
dream
-you now is a GOD
of your mind
-do whatever you
want to do in your dream, if you want kill someone in your dream, go ahead
because there is no law in your dream , if you want to fly , go ahead fly and
there is no law of gravity in your dream.
MY PERSONAL
EXPERIENCE ABOUT DREAM AND HOW I CONTROL THE SITUATION IN MY DREAM
30 JUNE 2012
I DREAM ABOUT A
HOUSE AND THEN I DESTROY IT WITH MY HAND WITH THE ENORRMOUS POWER FROM MY
HAND(EVER WATCHED DRAGONBALL?GOKU POWER)I FELT STRONG WAVES FROM
SURROUNDING AFTER I DESTROY THE HOUSE .
THIS IS MY STORY WHILE I'M AWAKE FROM MY DREAM MY ELECTRICAL DEVICES IN MY HOUSE IS
DAMAGE. (It is possible my brain waves is so strong and it causes some
electrical device is affected by it? The scientist maybe has an answer)
THEME OF THE DREAM
IS SOMETIMES INFLUENCED BY YOUR THOUGHT WHILE YOU AWAKE AND YOUR SUBCONSCIOUS
MIND PROCESS THAT INFORMATION TO BE EMERGE IN YOUR DREAM

do ghost actually give benefits for us , how do we know??
Harness of spirit is the next energy resources!!
- when they alive they store a lot of energy when we died we release that energy to this earth.
- since the earth begin there are approximately 10,0000000000000000 people who has live in this earth. Imagine the ghost around us right now, they could be everywhere.
- that energy if we the living not use for a good purpose it is waste of energy and for them itself because they live once and the memory of that places also keep the dead energy.
- the question is did reincarnation really exist , if it did well we are the cycle of that energy and ghost is definitely do not exist!
start thinking the impossible, the impossible could be happen in the next maybe 200 year after I wrote this!
computing basic knowledge
Why do we need ethic and law in computing?
- Respecting ownership
- Respecting privacy
- respecting property
an example of logic bomb is time bomb!!!
trapdoor or backdoor
- a feature in program that allow someone to access the program with special previllages.
worm
- a program that copies and spreads itself through a network!!
theft
- the act of taking something from someone unlawfully.

energy , transformers and efficiency
- Some energy is lost from a transformer as heat which mean that power output is less than power input
- Efficiency of the transformer is less than 100%
- When current flows in the coil, some power is dissipated as heat. This loss reduced by using thicker wire made of a good conducter like cooper.
- Changing magnetic field causes the electron in the soft iron core to circulate around as eddy currents. It produces heating in the core and causes further loss of power.
- Eddy current are reduced by using luminated core made up of a number of thin iron sheets glued together with thin iron sheets glued together with thin layer insulation between them.
- Core is continually magnetised and demagnetisation by the changing magnetic field produced by the alternating current in the primary coil.
- This energy loss is reduced by using soft iron for the core
- Magnetic flux produced by the primary current is not completely linked to the secondary coil.
- Some of the input energy is not transferred to the output of the transformer.
- This loss can reduced by winding the secondary and primary coils on top each other.
