The Arrow of Time and Tick-Tock Gene
Time is embedded in the fabric of laws of physics that governs everything in the Universe. Time is the main driver of all changes that happens in the universe. Time can be faster or slower it all depend on your perception of time. Time magnitude is different to different objects. Time depend on how fast or slow you can perceive it. If we measure time we find many fascinating facts.
For an example time it takes for a herbivorous animal to stand and run after birth is less than 5 minutes and time for the same activity by carnivorous animal is about a week and for humans is about a year and even more. So you can ask yourself why, and have many answers and questions too.
The arrow of Time pushes everything in the universe to keep on changing. Thats why Time is also embedded in our genes. I call this gene Tick-Tock gene. This gene is the one that sets and control all changes that need time management. This gene is the one that decides everything on what happens when. So for those who wants to stay young forever they have bigger battle against the clock that is ever going forward and governs changes accordingly.
One fascinating fact is that every month a human body receive new skin, but this new skin is made up of cells which by the control of TICK-TOCK gene they are new but Old according to the TIME (your age).
If this gene is ever isolated would we be able to slow it down or program it to the way we want? These are the billion dollar QUESTIONS.
So time is very interesting when it appears to run faster when you have a deadline and very slow when you are waiting for something to happen.

More on Big Bang Theory
So now we know that you and I and everything that your eyes can see and not be able to see are made of remnants of a dying star. This means we are made of a STAR. So as you walk along do not feel insignificant you are part of that STAR. (even religous texts support this)
As to what i thought about the beginning of that STAR, well is that there are two forces more like push and pull forces and these forces are the origin of the gravity force. When this two forces pushed and pulled together the materials thrown out of the BIG BANG, the material accreateated into minute vorteces which in turn increased the impact of the force pushing material ever closer to each other. As they got ever closer the heat became immense and glued these material together to form protons.
Therefore for more complex structures to form (atoms) the force pushing together had to be even higher than that, so any complex atom had to form as the star was being born. As protons formed their ever increasing number had to increase activities of these two forces (push and pull). Heat and Cold states of the space must have had huge impact in gathering these protons and form vortex or vorteces (BLACK HOLE) which brought them closer to form STAR structure.
The power of vortex (BLACK HOLE) amplified gravity forces to pull all these single proton atoms(HYDROGEN) together and in doing so increased temperature and that accelerated the whole action and in my mind the STARS have a very violent birth due to increased temperature difference between the center of the star birth point and its sorrounding and hence pull more atoms and once the point of nuclear fusion state is reached, the STAR become voracious feeder of the sorrounding atoms (HYDROGEN) and start shinning ever bright.

The Beginning of Everything (Big Bang Theory)
Last night i had a pleasure to watch a program called "Wonders of Universe" presented by Prof. Brian Cox, it awakened my thoughts on the Origin of everything..I remember last year i was talking to my Prof. and i had spent two nights thinking about how the universe came to be.
This kind of thinking is not new to me as i remember when i was very young walking in the moon-lit streets back in Africa whenever the sky was clear and stars were shining so bright i thought about why am i a human and where did we came from and what would have been of us if we were not humans and if there was no earth. Whenever i reached that point of asking myself what would have been if there was no earth my head would hurt and i would stop thinking. That was before i finished primary school.
I was thinking about the fact that all 92 elements that we know and believe that the entire universe is made of were actually originated from single hydrogen atom. I also think that there are seven more elements yet to be discovered. My question to myself was where did that Hydrogen atom came from and how it came to be.
we all know that the single hydrogen atom consist of one proton.. so how did proton came to be? i had answers and yesterday's program confirmed i was right!! more to come!!!

Placement at Oclaro
Lastly i have managed to get to Caswell where a company called Oclaro is based. i will be here for 3 months working placement. I will be working on Mach-Zehnder modulators..trying to figure out ways to reduce/eliminate one of the problematic characteristics affecting the devices. This menace is called frequency Chirp...it is caused by light carrying a signal travelling at different speed in the optical fiber such that the trailing edge arrive earlier or later than expected. This causes the signal to degenerate and limit transmission distance before you need a repeater...so that is the challenge.

The Power of Labview
I have been quite for sometime, and for a reason. i was wrestling some time consuming experiments, where i had to be in attendance to change currents on two Keathley CW power supplies. my experiment involved pumping two isolated sections of Quantum dot laser using two power sources. so manually changing current on one section and then scan wavelength on Optical spectrum Analyser (OSA), then typing the name of the file which has to show what section had what current for that scan was labour intensive until i met Labview...it is graphical programming language which at first glance a program may look like a spagheti dish.
But my programming skills finally came to the rescue and after a day of writing code, i was able to have a perfect program that had rendered me redundant from participating in my own experiment. YES the program does everything i tell ya, from switching the equipments on and off to perform loops that would have taken me a week to finish, and save the files conviniently into a folder with properly formated names.
Now all i can do is to wait for it to finish all experiments then i will take over to do analysis, am thinkin should i write a software that does the analysis for me and post me results (good idea but it my give my supervisor the opportunity to make me permanently redundant)...(DID YOU KNOW THAT GOD IS ALSO A PROGRAMMER)..just think about it!!!!
