Natural Phenomenon: Nacreous Clouds

Gambar
Polar stratospheric clouds  ( PSCs ), also known as  nacreous clouds  ( from  nacre , or mother of pearl , due to its iridescence), are clouds  in the winter polar st ratosphere  at altitudes of 15,000–25,000 m (49,000–82,000 ft). They are u sually spotted only near the poles, nacreous clouds form very high  in the atmosphere (twice as high as commercial airplanes fly), where the air is particularly cold and dry. However, they  are best observed during civil twilight , when the Sun is between 1 and 6 degrees below the horizon, as well as in winter  and in more northerly latitudes.   The colorful shine actually comes from the setting sun being lower  in the sky than the clouds, so they reflect sunbeams back toward Earth. Unfortunately, while they're beautiful, nacreous clouds also destroy ozone , the compound that protects us from the sun's most dangerous rays.  They are implicated in the formation of ozone holes.  The effects on ozone depletion  arise because they

Recommendation Letter

To: Oxford Scholarship Selection Committee I am writing this letter on behalf of Karin Astrid Wibowo, a student of SMAN 3 bandung who is applying for Oxford Scholarship program. I had the pleasure of teaching Karin in her 11th grade. From the very first day, she impressed me with her passionate self and how hardly she works when it comes to achieving her purpose. She always does her work wholeheartedly that it makes sense how the results are always exceptional. With many activities she joins outside school, she still manages herself to focus on her main goal and finds time to study. This makes her not only a talented person, but also a clever one. Other than that, she doesn't get distracted and quit easily. When she finds herself in a difficult situation, she pushes herself harder and believes that she could get through any obstacles that get in her way, which is true. Karin is also a creative person. She always finds a way to solve the problems she has to face. Her creativity

When we were staying in Desa Cibeureum, we frequently saw a lot of kids which are obviously underage rode motorcycles. They were riding it without considering their safety, such as not wearing helmet, speeding up, and they bought more than one person which doesn't fit the standard. We came into a conclusion that it was because the lack of transportation access in that area. So we think about making a public transport to make their lives more productive and effective. We think every district should have a stop station on some public places such as market, school, and government office. We think it'd be helpful if that vehicle is a cable car because it travels fastly and use less fuel. It also can attract more tourists to come to the district so it can increase the district's income. The cable car will arrive in every stop station every 2 hours. The capacity will be quite big; every cable car can carry approximately 15 people at once. This will save more time, energy,

Just Me

Hi. My name is Galuh Dilla. I was born on August 2nd 2002 in Purwakarta, West Java. I am my parents' first daughter and have a little sister. My family is a full of love and supportive one, which makes me very grateful. My parents are warm and understanding. They never demand or push me to do this and that. They put a trust in me, instead. They believe in my capability and think that I'm mature enough to decide something for my own good so even though they always keep an eye on my behavior, they never meddle in my business unless they're thinking I start to do something negative. This trust they put in me that always makes me want to be the best version of myself. When I feel insecure or feel like I'm-going-to-fail-anyway-that-there's-no-need-to-try-hard, I think about them and that they love me deeply and believe in me, so I have to believe in myself too. I also remember about how I want to make them proud and happy so I have to keep working hard. Furthermore,

  Edu Passion 2: Agranasta is an event that was held by SMAN 3 Bandung on February 24th 2019. This is an annual event whose purpose is to make the 12th graders sure about where they would go next. Nonetheless, this event is not only for the 12th graders, but also for the 10th and 11th graders as well.  In this event, some representatives of many university faculties come to SMAN 3 Bandung and present the detail informations about their faculties. There are also many booths from a lot of universities where the students can ask for more detailed informations. This way, the senior high students will get to know more about lots of universities and faculties so that they will be helped to choose the one they are most passionate about.   Talking about passion and what I want to be whe n I grow up, I think I want to be a psychiatrist because I want people to realize that mental health is as important as physical health. What I see from society nowadays is mental health is
