Tigil na yan! ang traffic eh!
“The Last Goodbye” By: Jade Michael Ada
Creating the perfect memory of someone is hard especially when you haven't seen that person for so long. Memories fade and are forgotten on the long run. But some memories stay with you forever and dig deep into your heart. Those kinds of memories will never be taken away from you.
I once had a friend who was one of the closest that I had. We were always together and did almost all things together. We even shared our secrets with each other! We loved each other like a brother and a sister would. But something happened that changed it all.
He died when we were still in elementary. He died on the summer of April 2005.
Poor Dick…
He was such a good kid…
Many of our classmates, teachers and those who knew him and his family went to his wake. It's funny how we were so close yet; it was the first time I met almost all of his relatives including his mom and dad.
His mom and dad just arrived from London. They work there, and left their children here in the Philippines in the care of their grandparents and other relatives.
After the mass, his mom came to us. She was at first shy because she just recovered from a sickness that covered her face with small red dots- as scars. They hurriedly came back when they learned about their misfortune.
I personally didn't know the story of his death because it was just after recognition and everyone else were busy with their own vacation.
With that as the case, she offered to tell us how he died. Her story went like this.
Dick and his relatives went to Manila for their vacation. They went to a resort and spent hours lounging in the pool. Even though his relatives were there, it didn't stop the accident from happening.
His relatives were busy when he suddenly slipped and drowned. Apparently, people stepped on his body and eventually he died.
In the morgue, they saw bruises all over his body, especially his chest. They're guess was, people must have stepped on him unexpectedly.
His mother cried after she told us what really happened. She also mentioned that she could identify his (Dick) friends, because we would stop and cry when we pass by his coffin. Upon hearing that, I looked around and saw his brothers and sisters still traumatized at what happened. Dick was their ultimate favorite, the youngest among them; they loved him like no other. His dad said nothing more but good stuffs about him, how he was as a son and as a brother.
The day of his funeral came. We walked to the cemetery all dressed in white. His family had been crying ever since we left the church.
In the coffin, as I have observed, they've put his favorite toys: small guitar, piano, his phone, and some other things that I can't remember.
Someone texted him! His phone rang. I thought then that maybe it was a prank. But after thinking about it for a few minutes, I guess someone sent him a last message. Perhaps to tell him, how much he/she loved him.
We said our goodbyes and laid our flowers. I remember the flower I had held in my hand. It resembled a carnation flower but it was yellow which held my curiosity for a brief moment.
As the coffin was pushed inside, his family couldn't stop wailing about how they miss him and why this happened to their family and especially, why Dick? His sister got it hard. She fainted as the coffin was being pushed inside. It's a good thing that one of his brothers was there to help her.
After graduation, I went to his grave and visited him, talked to him about all sorts of things and how we missed him terribly. I also told him I really wished that he would have graduated with us. I had a lot of fun talking to him, even if he replied no more.
That was not the first time I visited him. The first time was with my classmates. We visited him on his birthday, then on his death anniversary. His relatives were there. Like us, they brought flowers and candles and offered prayers for him. They caught us there. O.o It was rather embarrassing.
After that, we haven't seen them again. We later learned that their whole family moved to London. This past month, I saw them on a social networking site called Facebook. I guess their parents would not risk losing a child again.
His death caused a major change to the people who knew him. I realized that time on Earth is short, and we must try our best to do good to other people and to make every moment special.

The effects of stress on Health
"I'm so tired"
This is what we usually hear from busy people. They complain how they are so tired from work, etc. You can hear them wishing that they would be treated out to relax sometime. But, have you ever wondered how and why they become stressed? How do we prevent this?
According to Wikipedia, there are three kinds of psychological stress. They are the chronic stress which is a persistent stress which can lead to illness and mental disorder, Eustress- a positive stress that can lead to improved long-term functioning, and lastly, the workplace stress- a stress caused by employment.
I personally think that stress can affect every aspect of a person's life. This is because if a person is stressed, he would not be able to perform well all his duties. When this happens, he will be affected by it, then, even his relationships towards will also be affected.
Not only that, stress can also affect our health. I think that stress can give us a headache, cause hypertensions, confusion and suicidal thoughts. I came up with the idea that it causes suicidal thoughts when some confused people want to escape reality, the idea of dying becomes an option.
All of these ideas were supported by the article I've read. As what I thought, stress does affect our health. According to the article, it can cause heart failure, and stroke. It can also affect us psychologically.
According to the international stress Prevention Centre, that was established in 1981 by an Israelite, kiryat Shmona, there are a lot of ways to prevent stress. Preventing and relieving stress is easy if you would just be creative enough.
So if you feel stressed maybe you can sleep, talk to someone or seek guidance, or keep a tress diary where you put the details of your attack, so that you will know what triggers it.
Therefore if you feel stressed, don't jump to the idea of dying. There is more to life than you ever imagined. So be stress-free and be happy. Besides, "All work with no play, makes jack a dull boy."

Bose Einstein Condensate
Hi guys! Im back! Its Science time! This is actually our Homework in Chemistry.. I figured out that not all people know this 5th Phase of matter. So here it is! I just took out the essential stuffs!
Bose–Einstein condensate
From Wikipedia, the free encyclopedia
It has been suggested that Bose–Einstein condensation: a network theory approach be merged into this article or section. (Discuss) Proposed since April 2011. |
Velocity-distribution data of a gas of rubidiumatoms, confirming the discovery of a new phase of matter, the Bose–Einstein condensate. Left: just before the appearance of a Bose–Einstein condensate. Center: just after the appearance of the condensate. Right: after further evaporation, leaving a sample of nearly pure condensate.
A Bose–Einstein condensate (BEC) is a state of matter of a dilute gas of weakly interacting bosons confined in an external potential and cooled totemperatures very near absolute zero (0 K or −273.15 °C[1]). Under such conditions, a large fraction of the bosons occupy the lowest quantum state of the external potential, at which point quantum effects become apparent on a macroscopic scale.[examples needed]
This state of matter was first predicted by Satyendra Nath Bose and Albert Einstein in 1924–25. Bose first sent a paper to Einstein on the quantum statistics of light quanta (now called photons). Einstein was impressed, translated the paper himself from English to German and submitted it for Bose to the Zeitschrift für Physik which published it. Einstein then extended Bose's ideas to material particles (or matter) in two other papers.[2]
Seventy years later, the first gaseous condensate was produced by Eric Cornell and Carl Wieman in 1995 at the University of Colorado at BoulderNIST-JILA lab, using a gas of rubidium atoms cooled to 170 nanokelvin (nK) [3] (1.7×10−7 K). For their achievements Cornell, Wieman, and Wolfgang Ketterle at MIT received the 2001 Nobel Prize in Physics.[4] In November 2010 the first photon BEC was observed.[5]
The slowing of atoms by the use of cooling apparatus produced a singular quantum state known as a Bose condensate or Bose–Einstein condensate. This phenomenon was predicted in 1925 by generalizing Satyendra Nath Bose's work on the statistical mechanics of (massless) photonsto (massive) atoms. (The Einstein manuscript, once believed to be lost, was found in a library at Leiden University in 2005.[6]) The result of the efforts of Bose and Einstein is the concept of a Bose gas, governed by Bose–Einstein statistics, which describes the statistical distribution of identical particleswith integer spin, now known as bosons. Bosonic particles, which include the photon as well as atoms such as helium-4, are allowed to share quantum states with each other. Einstein demonstrated that cooling bosonic atoms to a very low temperature would cause them to fall (or "condense") into the lowest accessible quantum state, resulting in a new form of matter.
This transition occurs below a critical temperature, which for a uniform three-dimensional gas consisting of non-interacting particles with no apparent internal degrees of freedom is given by:
where:
is | the critical temperature, | |
is | the particle density, | |
is | the mass per boson, | |
is | the reduced Planck constant, | |
is | the Boltzmann constant, and | |
is | the Riemann zeta function; (sequence A078434 in OEIS) |
Current research
Compared to more commonly encountered states of matter, Bose–Einstein condensates are extremely fragile. The slightest interaction with the outside world can be enough to warm them past the condensation threshold, eliminating their interesting properties and forming a normal gas. It is likely to be some time before any practical applications are developed.[citation needed]
Nevertheless, they have proven useful in exploring a wide range of questions in fundamental physics, and the years since the initial discoveries by the JILA and MIT groups have seen an explosion in experimental and theoretical activity. Examples include experiments that have demonstrated interference between condensates due to wave-particle duality,[14] the study of superfluidity and quantizedvortices, the creation of bright matter wave solitons from Bose condensates confined to one dimension, and the slowing of light pulses to very low speeds using electromagnetically induced transparency.[15] Vortices in Bose–Einstein condensates are also currently the subject of analogue gravity research, studying the possibility of modeling black holes and their related phenomena in such environments in the lab. Experimentalists have also realized "optical lattices", where the interference pattern from overlapping lasers provides a periodic potential for the condensate. These have been used to explore the transition between a superfluid and a Mott insulator,[16] and may be useful in studying Bose–Einstein condensation in fewer than three dimensions, for example the Tonks-Girardeau gas.
Bose–Einstein condensates composed of a wide range of isotopes have been produced.[17]
Related experiments in cooling fermions rather than bosons to extremely low temperatures have created degenerate gases, where the atoms do not congregate in a single state due to the Pauli exclusion principle. To exhibit Bose–Einstein condensation, the fermions must "pair up" to form compound particles (e.g. molecules or Cooper pairs) that are bosons. The first molecular Bose–Einstein condensates were created in November 2003 by the groups of Rudolf Grimm at the University of Innsbruck, Deborah S. Jin at the University of Colorado at Boulder and Wolfgang Ketterle at MIT. Jin quickly went on to create the first fermionic condensate composed of Cooper pairs.[18]
In 1999, Danish physicist Lene Vestergaard Hau led a team from Harvard University which succeeded in slowing a beam of light to about 17 metres per second[clarification needed]. She was able to achieve this by using a superfluid. Hau and her associates at Harvard University have since successfully made a group of condensate atoms recoil from a "light pulse" such that they recorded the light's phase and amplitude, which was recovered by a second nearby condensate, by what they term "slow-light-mediated atomic matter-wave amplification" using Bose–Einstein condensates: details of the experiment are discussed in an article in the journal Nature, 8 February 2007.[19]
Researchers in the new field of atomtronics use the properties of Bose–Einstein condensates when manipulating groups of identical cold atoms using lasers.[20
