## Geometry and Ratio

This is the second term of 2018 – 2019. We finished Primary Mathematics 5A book and about to start the new one. For this term, we are learning Geometry and Ratio a lot which give the ideas what it’s like to measure shapes and using ratio as a daily life in the future. For example, if you having a job and you need to manage your money on needs, wants and save which ratio would help. It’s also help comparing the different between things easily especially, gender.

For geometry, we are focusing a lot on finding areas especially for triangles and rectangles. As we start learning geometry, it’s leaning from first by counting grid and later calculation until solving harder and harder problems. Sometimes, it’s hard as it more difficult for the word problems, but that’s things need to be challenge in math. However, solving problems always have technique to solve it easily especially try to understand it at the very first start.

## Photography Basic

As I said in the description of me that hobby make me become a great photographer. I like photography in this reality world. In my multimedia class which I learned more basic about photography which is the exposure triangle, it consist Shutter speed, Aperture and ISO. These are basic knowledge that we make our photos better and its editable, but mostly photographers use modes in camera as Aperture mode which easier to be flexible by using it.

Shutter speed is one mode in the exposure triangle that mostly used to capture motion. It’s measure in fraction of a second. The higher the shutter speed is, it can captured motion easily, but it’s will bring less light. The lower the shutter speed is, it will bring more light, but can’t easily captured the motion.

Aperture is the size of opening lens that let the lights come through the camera. The wide aperture will has a shallow depth of field. The narrow  aperture will has a deep depth of field which is good for landscape, scenery and long shot. Depth of field is the changes of the background which change into blurry or not.

ISO is how sensitive your camera is to light. Once we have no more choice to let the light come through the camera by changing Aperture or Shutter speed, we would want to increase the ISO. When higher the ISO, the more noise it will create in your photo which make it hard for editing and also it’s don’t look good.

With this technique, it’s will make photo has a good quality with it, but also we technique to take photo and different angle to make it more effective, give more details and showing emotion. Most photographer use Long shot, Full shot, Medium shot, Close up, Extreme close up, Low angle, High angle, Eye level, Dutch angle/tilt, over the shoulder or bird’s eye view.

## #1 How I change Cambodia

What am I born with? Nothing! Everyone is born with nothing even clothes, money or knowledge. What are many millionaires, billionaires or royal family born with?  They are all the same. Just like some of those people born as a high class family or a low class family. I do know this is our destiny, but if you have a great destiny, you should never look down or even have a stereotype to someone especially women. In Cambodia, this stereotype to women happen since the 12th century. People always said “Women stayed home, men went out and work”. This phrase is annoying. It’s already gone and the new world and new technology is growing.

I have been doing many projects through this year, but some of it was about the stereotype that people been confusing especially girls in technology. I joined Technovation which is a program for girls in technology. To join this program, it is very convenient for persuading girls. I joined the program for two years and I see how it’s changing by girls in technology. In 2017, there aren’t many girls interested, but in 2018, there are twice more girls than last year and it makes me proud to see it. The population of girls joining this program was really fast because of the girls who won to San Francisco, America. Even though, I am not one of them, but I am one part of Technovation who empowering girls. This program make other girls change their stereotype including me.

In the early 2018, I got to go to Singapore for the Robotic competition which participate by many schools in Southeast Asia and East Asia. It was difficult and needs to work hard for it. Even though we got only seven weeks to go, but we tried our best to do it. There are also judges that judge on our presentation about problem and solution of water, but one question had come out from them. Did you girls do this project and the boys code the robot? It’s come out as a stereotype. We answered that we all worked together and there’s no worked assigned by gender. Gender equality is still happened even though the society said no more stereotype. However, I already change some of the people mind which say no stereotype to girl which they always said no girls in technology. As I share it to three people, it already means I shared it to the world.

To sum up, what I write about How I change Cambodia is basically to stereotype based on girls. To change stereotype and to have gender equity for our women. Even though it just a little change, but I’ve changed it. To change a big world is starting from the little changing. As like one quote said “In a gentle way, you can shake the world” – Mahatma Gandhi.
