Microcosmos Physical Sciences
Microcosmos Physical Sciences
I saw video about insect in class. It was made me interested. I had experience about insect also. Last year, when I work up. I feel itchy at my arm. I took off my cloth and I saw a lot of red spots on my arm. I don't what going on I though may be I got allergy from something but I call my friend. I explained everything. She said may be bedbugs. I don't have idea about that. I went to hospital and told them.
A bedbug is a small nocturnal insect of the family Cimicidae that live by hematophagy, or by feeding on the blood of humans and other warm-blooded host.
Bedbug can live for year or as much as eighteen months without feeding, they typically seek blood every five to ten days. Pattern of bites in row or a cluster are typical as they maybe disturbed while feeding.
Location, Bedbug travel quickly along pipes and boards, and their bodies are very flat. In the day time they stay out of light and hidden in such places as mattress seams. bed frames, nearby furniture, inner walls, tiny wood holes also.
We can control them by wrapping bedding in plastic that would cause your mattress and box springs in impermeable beg bug bite proof encasements after treatment. There are product on the market also.
After, I came back from hospital. I use medicine for my skin and move out to another apartment. Last week, My friend just got bedbug on her skin. It is a scary in my experience.

Science Essay "Black Holes"
Black Holes
I studied science in hight school about galaxy. I think so interested for my because there are a lot of thing for example stars Milky way galaxy dust dark matter. The name is from the Greek root galaxias [γαλαξίας], meaning "milky," a reference to the Milky way and another thing is Black hold. Last week, I saw video about Black Hold also.
A black hold is a theoretical region in which the gravitational field is so powerful that nothing, not even electromagnetic radiation, can escape its pull after having fallen past its event horizon.The term derives from the fact that the absorption of visible light renders the hole's interior invisible, and indistinguishable from the black space around it.
According to this mass/size criterion then, black holes are commonly classified as; Supermassive black holes, that contain hundreds of thousands to billions of solar masses are believed to exist in the center of most galaxies, including our own Milky Way. Intermediate-mass black holes, whose sizes are measured in thousands of solar masses, probably exist. They have been proposed as a possible power source for the ultra- luminous X ray sources. Stellar-mass black holes ave masses ranging from a lower limit of about 1.5–3.0 solar masses. Micro black holes have masses much less than that of a star. At these sizes, the effects of quantum mechanics are expected to come into play.
In my opinion, In the galaxy might be have other species or another universal stay somewhere ?

Social Sciences Essay " YA-BA in Thailand "
Ya-ba in Thailand
When I visited my parent last year 2004. I had a dinner with my family and my friend. I watch television with them. I saw the reality talked about Amphetamines or "Ya ba" problem. They reported about someone recorded the man who took amphetamines and he had a knife. The polish tried to catch him but he catch a student to be a hostage by knife who walked pass to the train station to went home near my University "Kasetsart University" and he asked about the pic-up car and driver also otherwise he will kill the student. The student was a women who was a just entranced in my University.The polish gave him everything and he took the student at the truck but he still hold a knife on her neck all the time until she dried and the polish shot him also. I saw about the show. It made me upset because the student was schoolmate in the same with me.
I thing her family had to be upset.My family told me about my friend who live near my house. he took Ya-ba. He lived with his mom because his mom got divorced.I didn't know what going on about why he took Ya-ba. Last month he tried to asked money to bought Ya-ba but she tried to stop him but he got angry because he took Ya-ba and effect of drug he hit his mom. She ran away from her house and ask help.

That is a big problem in Thailand. I concern about that problem. Do you know it easy to but drug. When I was in teenager. I spent time with my friend in the club everyone took drug except me. I ask them about why do you used it? They said it made them happy. I didn't say anything just umm. If the government can't stop this problem.New generation still took drug. I though my country will be go down because doesn't have enough human resource to develop my country.
Golden gate bridge
Golden Gate Bridge
Three year ago, My sister visited me. She came from Thailand. I talk with her before one week. I asked her about what would you like to go in San francisco. She said Shopping and the famous place in San francisco include Golden Bridge also. When she came in San francisco. I went there together and I told her that this is the first time of me also. She laugh at me and asked about what going on with you because I stay here three years ago. I said I don't know and we walked cross the bridge together. That day was so lucky because the weather was sunny.
Golden Gate Bridge History
The Golden Gate Bridge had the longest suspension bridge span in the world when it was completed in 1937, and has become an internationally organized symbol of San Francisco. The bridge connects the city of San Francisco on northern to Marin Country. Although the idea of a bridge spanning the Golden Gate was not new, the proposal that eventually took root was made in a 1916 article by former engineering student James Wilkins.
Design
Irving Morrow, a relatively unknown residential architect, designed the overall shape of the bridge towers, the lighting scheme, and Art Deco elements such as the streetlights, railing, and walkways. The famous International Orange color was originally used as a sealant for the bridge. Senior engineer Charles Alton Ellis, collaborating remotely with famed bridge designer Leon Moisseiff, was the Principal engineer of the project.
Construction
The project cost more than 35 million. Construction began on 5 January 1933.Strauss remained head of the project, overseeing day-to-day construction and making some groundbreaking contributions. A graduate of the University of Cincinnati.he had placed a brick from his alma master's demolished McMicken Hall in the south anchorage before the concrete was poured. He innovated the use of movable safety netting beneath the construction site, which saved the lives of many otherwise-unprotected steelworkers.The project was finished by April 1937, $1.3 million under budget.
Opening festivities
The bridge festivities opening celebration began on 27 May 1937 and lasted for one week.The day before vehicle traffic was allowed, 200,000 people crossed by foot and roller skate. On opening day. Mayer Angelo Rossi and other officials rode the ferry to Marin, then crossed the bridge in a motorcade past three ceremonial "barriers", the last a blockade of beauty queen who required Joseph Strauss to present the bridge to the Highway District before allowing him to pass.
