Smartphone Cameras




As you may or may not know, I am super into technology.

In this video the presenter (MKBHD), was explaining how smartphone cameras work. 

At the start of the video he fixed a common misunderstanding, the more megapixels, the better the camera. 

The things that matter are the sensor, image stabilization. aperture, and processing.

The bigger the sensor the better. For example the Nokia Lumia 1020, has a HUGE sensor.

Image stabilization comes in two forms: Digital Image Stabilization (DIS), and Optical Image Stabilization (OIS). OIS is better because, it has a gyroscopic device that stabilizes the image while DIS is computer generated.

Aperture describes the amount of light let in.

As you can see f/1.4 has a larger opening to let more light in.

Processing is based on how the smartphone takes in the image. For example some phones may over expose the image and Some may under expose.

Matter Unit Test

After weeks of studying matter we had a unit test. I scored a 93% on it.

That means I got two questions wrong.


The first question I got wrong was this:


"Four materials are put into small containers. These materials are then moved from the small containers into large containers. Which materials will spread out to completely fill larger container?"
A. air
B. ice
C. sand
D. water


I chose water because, I knew that it could change shape. I just did not read the word "completely," so I got it wrong. The correct answer is air.


The second one I got wrong was:


"Within a substance, atoms that collide frequently and move independently of one another are most likely in which state of matter?"
A. liquid
B.water
C. gas
D. solid



I chose liquid because, I thought if they collide frequently they will be a liquid, but liquids slid past one another. The correct answer was C.




I definitely could have gotten a higher score. My pretest score was a 67% (and that's when we did not learn anything yet). Myt grade raised by 26%!

"Norm of the North" Teaches a Good Lesson



Last weekend I watched a movie called "Norm of the North".

This movie has some terrible reviews on Google, but I really enjoyed it.

The movie is about a polar bear named Norm and a businessman who wants to build homes in the arctic.  Norm has to stop humans from building homes in the arctic. He has a special ability to speak in "human". With this ability he has to save the arctic from the humans.

In real life animals in the arctic cannot save themselves and their habitat. As humans we must step up and save it for them. The move shows how helpless animals can be when they are abused and when humans are taking their habitat.

Is Quizlet Helpful?






video
Sorry about the bad Video Quality
In my opinion Quizlet is amazing. 

It helps me study for my tests and can even support different languages (which is very useful for Spanish).

In the video above, I show you a quick tour of the Quizlet app. If you cannot download the app you can simply go to www.quizlet.com. It has all the same things as the app, plus another game called "gravity" which is very helpful if you want to memorize the spelling of words.

On top of all that you can create your own Quizlets or just simply search one up. 

I hope to use Quizlet in the many test and quizzes to come.

Magna Carta

Yesterday in social studies class we learned about the Magna Carta. The story of the Magna Carta is shown in this video.

Basically, the Magna Carta was an agreement between King John and his barons. Though King John signed it he did not agree with it. He went on a rampage declaring war on his barons.The barons sided with France and defeated the king. King John's son succeeded him.

The Magna Carta has a big impact on how we live today. If it was not written we probably would not have equal rights. Also, many other documents such as the US Constitution were inspired by it.

I hope to learn more about how it impacted other kingdoms during the middle ages.
