Global warming : Ozone Hole

Halooo friends...

I'd like to share with you about ozone hole. Ozone is a layer that protects Earth from ultraviolet rays. But now, ozone layer is damaged because chemical industry pollution. Even ozone layer in Antarctica has been perforated. The ozone layer protects the earth from exposure to Ultra Violet B (UV-B) which is very harmful to living things on earth. UV-B which has a wavelength of 280-315 nm, some is absorbed by the ozone layer, thus the amount of UV-B reaching the earth very few. Exposure to UV-B on humans can cause skin cancer, cataracts and reduce the immune system. UV-B exposure can also damage plant life, single-celled organisms and aquatic ecosystems. And than ice in the North Pole melts. It is very dangerous for species animals in the North Pole because they will lose their habitat.

The ozone destroy due CFC. CFC found in AC, refrigerator, push the material in throwers (aerosols), including spray cans for air freshener, hair spray or perfume. One CFC molecule has a lifetime of 50 to 100 years in the atmosphere before it abolished. Within about 5 years, CFC moving up slowly into the stratosphere (10-50km). CFC molecules break down after mixing with UV light, and release chlorine atoms. It attempts to destroy the chlorine atoms and ozone generating ozone hole. Depletion of the ozone layer will lead to more UV rays enter the Earth.

We must stop using CFCs and replace with other subtance which more friendly. 

My Classmate, Anti by:Belinna Wijaya

I have a classmate in Binus, her name is Diah Rostanti Fadilah. People usually call her Anti but i just call her Ti. she is my first friend in Smart Class. She was born in Tegal , 24th December 1993.

My Comment About Problem Solving Strategies

 Every student have a problem. This is problem solving strategies from Algebra. that is understant the problem , situation, information and what the question is asking. For many problem , drawing  a cleary labeled pisture is very helpful. and then the plan: first focus on the objective, than look the given information, and if the information don't unreasonable look at the given information often will find another piece of information can use the answer the information.use the mathematical system of logical relationships between information given and the answers you seek. This involves: use the symbol to the number represented. The most frequently used is x, but it's better to use remember  symbols that represent what is in. Translate Englist to math, because because mathematics is a language that is suitable to describe logically.

Read the problem with caution, determine what is known, what is not known and what was asked, represent unknown quantities in terms of a variable , use diagrams where appropriate., find formulas or mathematical relationships between the knowns and the unknowns ,solve the equations for the unknowns.  ,check answers to see if they are reasonable.

Example:  Find a number such that 5 more than one-half the number is three times the number

Let x be the unknown number.
Translating into math:	5 + x/2 = 3x
Solving: (First multiply by 2 to clear the fraction)	5 + x/2 = 3x 10 + x = 6x 10 = 5x x = 2

Wyvern

Like the dragon, the wyvern is rendered as a winged reptilian creature.the wyvern The Wyvern has the head of a dragon, and its forked tongue, scaly neck and leathery wings, but combines with these the two clawed feet of an eagle. The Wyverns were vicious, bloodthirsty and extremely powerful creatures. On top of being able to expel fire from their noses, these dragons always had a breath that reeked of recently killed and devoured flesh, their bellies usually observed as bloated with obvious signs of a recent feast. These beasts were exceptionally powerful and evil to the core so anyone who could conquer and kill one was deemed to be a dominant force and supreme hero. Depicting a trophy image in its likeness in any form, whether at the tip of a pirate ship or as part of a coat of arms; was indeed considered a form of extreme strength and superiority.

Future Gadget

Now,  we are talking abour future gadget. in future glasses not only for eyes minus but also can be more for various kind. it will probably can translate the languange. so this glasses can to listent, to foreign languages and highlight a direct translate into the eyes of the wearer.but the wearer can still see the person they are talking. translate are sent and flashed to retina use after-image effect.

 

and then, the glasses will be can display the interactive data. it may can display the interactive data with the sensor of the retina. it will probably help the paramedic during operation, mechanics, technicians. so no need to switch the view to a computer or PDA.but this glasses won't happen see your future because your future just you know.
