200-year-old fossil mystery resolved

News link

   

Called plesiosaurs are predatory marine reptiles that lived at the time of the dinosaurs. The plesiosaur was discovered by the fossil hunter Mary Anning in 1821. Scientists have reconstructed this ancient reptile. 

On the last years the scientists tried to know how this reptile moves. The debate has continued until today, because the paleontologists were divided on whether the marine creature used its four limbs for rowing like turtles and penguins or some sort of combination of the two. The study, published in the scientific journal PLOS ONE, is based on a computer simulation of a Jurassic fossil from Germany. This simulation suggest that the plesiosaur moved through the water like a penguin, using its front limbs as paddles and back limbs for steering.

Dr Smith and co-researchers at the Georgia Institute of Technology in Atlanta say: "We conclude that plesiosaurs were forelimb-dominated swimmers that used their hind limbs mainly for manoeuvrability and stability." 

This Super Stylish Smartwatch Was Designed for the Blind

Students and entrepreneurs from the United States and South Korea has developed a smartwatch for the blind. This smartwatch is called Dot and can show four braille characters at a time. Each character space has six active pins that rise and fall to produce the combinations of the braille alphabet and numerical system. 

The watch connects vie Bluetooth to a smartphone and uses a actuator powered by magnets to raise and lower the pins. Dot can shows texts, notifications, tweets and the time. If the user recive notifications this machine will vibrate. Before this new invention the blind people only can use smarthphones with vocal systems like Siri to read texts out loud.

You can start to buy Dot in the United States and Canada sometime in 2016 for $300, more cheaply than the existing braille machines.

This will be so helpful for the social life of blind people, but I don't think that is extremely necessary for a person.

Virtual reality

Currently the virtual reality is on the top the of innovation in the entertainment industry and many enterprises (like HTC, Sony, Microsoft and Facebook) are interested in this and they invest a lot of money to be the first. But now a days not all the people can buy this because for the moment it isn't on the market. When you play with any machine of virtual reality, you can see thanks a special glasses a new world (the world of the video game that are you playing). When you move the head the glasses detect this movement and move the screen that you see with the same direction and movement that you move your head. Fortunately this technology is very investigate and on less than a year this virtual reality will be on the market, but no one knows the price of this.

Hunger games mockingjay-part 2

The film is the second part of the third film of the trilogy of The Hunger Games. It's important that you saw the others films, because if you didn't see the others, you don't know the beginning and the story, or the other possiblility is read the books. The story continues with Katniss in the sector 13. They are preparing the war against the Capitol. At first katniss only help the sector 13 with her image, because she is the symbol of the revolution, and when the soldier see him they are more encouraged. Katniss was wishing that the sector 13 rescue Peeta and the other tributes, but when they return her best friend, discover that the Capitol manipulated Peeta to use him like a weapon against Katniss. For this reason she decide go with the soldiers because she wants to kill the president Snow, the leader of the Capitol. During the way to go to the President's mansion, she and her troop's colleagues, they had to pass a lot of enemies and taps, and most of them died. Finally the sector 13 wins and capture Snow. When Katniss was on the square to kill the president Snow with an arrow, but he discover that the bombing who killed her sister was produced by the sector's 13 forces and not by the Capitol's forces, and she diced to kill the sector's 13 leader. This means that she had to leave to her house where she and Peeta created a new life.

This film is better than the last but it isn't the best. Principally because the third book it isn't more good thant the first or the second, in my opinion. But is a good film because is exactly or quite exatly than the book and I enjoy it.

Google

For my this presentation has two good things, the presentation and the content. Because if you see it, you can observe that I put a good bit of time. And the content have quite information that it's possible that you did know before. Also the language was difficult for me because this is varied and specific for this topic. But the downside of the presentation was my body language and eye contact, because unfortunately I needed to read all, and my pronunciation some times wasn't good.

Garbage islands

Currently exist five islands of garbage that each contains a large amount of tons of plastic. The first island discovered was in 1997 in the Pacific Ocean. But is not the only one because also exist more islands on the Atlantic and Indian Oceans. The biggest island measure more than 1500000 km2.

They are formed by trash and waste from continental areas and also some part of the ships. All of this trash join together by vortex of ocean currents. Unfortunately these islands are moving all the time by this ocean currents, and pollute and destroy the marine ecosystems. The animals eat the trash and die, and the sun with the trash release toxins and kill the animals too. The last consequence is that the seaweeds don't receive the enough light for do the photosynthesis

Email to the teacher

I have not studied much for any subject so far, I haven't made the effort. I only had to listen to understand the lessons. But batxillerat is another story.

In this moment the unique objective thaht I can think for the future is the university, and I wish to live that experience and enjoy it. But the problem is on 2 batxillerat, because I can't focus too much in any subject and this is a big problem for now and for the future and I think that I can't overcome batxillerat without some difficulty. Another dificculty during this years is the Research Paper, because the topic that I chose is boring and I don't enjoy when I do the work.
