TED TALKS: Jason deCaires Taylor: An underwater art museum, teeming with life

Jason deCaries build underwater museums in Grenada and Mexic, also he build a underwater botanical garden which represent the climatic change and the protection of the sea. In the Bahamas he make a statue of five meters.

He use a cement with a neutral pH for that reason his job is more stable and for that reason coral can live in. Also can live in fishs and other kinds of animals because his statues are hollow. All his statues are awesome becuase the nature finish his work and they are part of the sea.

He do it becuase he think that we don't protect our oceans enough. And one way of thinking about this is that we don't regard our oceans as sacred, and we should. 

TED TALKS: Carl Safina: What are animals thinking and feeling?

Carl Safina make a study to understand the feelings of animals. 

The first neurons came from jellyfish. Jellyfish gave rise to the first chordates. The first chordates gave rise to the first vertebrates. The vertebrates came out of the sea, and here we are. A neuron looks the same in a crayfish, a bird or you. Dolphins have a bigger brain with more convultions. Okey, they  have brains, but what does that have to say about minds?

He observe elephants. He saw that the elfants know where is a human here and if that human is dangerous or not, they can differentiate. They have been watching us for much longer than we have been watching them. They know us better than we know them. We have the same imperatives: take care of our babies, find food, try to stay alive. 

We are the animal more compassionate, most violent, most creative and most destuctive. Those animals of Noah's ark deemed worthy of salvation is in mortal danger now and their flood is we.

TED TALKS: Angela Lee: the key of success? Grit

Anglea Lee was a teacher who do tests and exams. She saw that the marks of the best students and the marks of the worst students don't have so much difference. She thinks that in education lack a prespective psychological for be able to understood how learns the students. Due to that she go to university to learn psycology.

She allways ask: who have success and why? For that reason she make a study shows the key of success isn't only IQ, talent or pshysical healt. The most important thing is have grit. Gritt is perseverance and passion for very long term goals. But we don't know how building grit.

Drugs

There are proves that the man used drugs for religious reasons, for example for being able to talk to their gods.

One of the first drugs was the opiate in Mesopotamia. 

Kinds of drugs :

-Hallucinogenic: Substances that modify consciousness, perception and thinking. LSD and some mushrooms are among them. In California it is forbidden to lick frogs because of its toxins.

-Opiate: Substances stemming of the papaver. For instance there is morphine.

-Depressing drugs: They act on the nervous system, decreasing its activity. They are often used to decrease anxiety and inducing sleep.

-Stimulants: These enhance brain activity and mental focus. But heighten blood pressure, heart rate beat and breathing rate. These used to be used on asthma patients.

Kinds of consequences :

Depending on which drugs you use the consequences may vary. Some examples:

- Addiction is the most known since it is present in almost every drug. Addiction makes you want to keep consuming regularly and without control.

- Panic attack: Appears after the consumption of cocaine or marihuana.

- Aggressive behavior :Caused by methamphetamines.

- Hungry: Caused by amphetamines.

- Chronic hallucination: Caused by LCD.

- Focusing issues: Caused by alcohol.

- Dilated pupils: Caused by cocaine.

- Red eyes: Caused by marihuana.

- Among others, including sterility, AIDS, etc.

Penguins

There are seventeen different types of pinguins. They can be from forty centimetres to more than one metre tall. They all lives in the south part of the world. In winter, they swim a long way to find warner weather.

 In spring, much penguins come together on the beaches of Antartica. The female penguin has one or two eggs. She puts her eggs on the ground and sits there to one egg between their legs.

When the female penguin is sitting on the eggs, the male penguin brings her food. He also does this when baby penguins are born.

Whales in Cap de Creus

This year, in September 6 whales came to the Cap de Creus. We can  think that it isn't typical, but it isn't. Some kind of whales are typical from here.

One of those whales had a big scar due to boats. For that reason I remember that we have to respect mammals and animals because so many are in danger of extinction.

The firs time that I saw whales was in Madeira. They were free and wild because of that I didn't see many. I wanted to see them more, it was impressive.

Life without technology?

Would we bertter off without computer games? So many people have a opposite opinion about that, forr that reason I will explain the positive annd negative things.

Firstly, technological machines are useful because they help us to do things more easily and they facilitates work. For exemple our phones make it eazier to comunicate with someone, or the robot vacum clener that cleans the floor on this own. Our machines help us.

On the other hand, tecnology makes us lazy because they can do everything. Morover they are expensive and they can break

. Finally technology dosen't work without power.

Like many things, maybe it's a questtion of balance. We can use them but not depend on them, because they can give bad habits. Life with technology is better if we are careful.

Life without computer games?

Computer games have been with us for years. For a lot of young people they take a significant amount of their free time. But are they a positive or negative thing? Would we better off without them?

Computer games can be a fun way to relax after studying. They don't disturb other people and can be good for imporving had-eye coordination. On the other hand, they can be addictive and some people spend many hours at their computer. They stop going out, seeing people, doing sports and so on.

So, in the end, like many things maybe it's a question of balance. If we play computer games from time to time and still do lots of other things, they should be a fun and entretaining addiction to our free time interests.

The trip to London

Last week I went to London for four days. We had to take a bus on thusday at 2:00 a.m. for the early flight from Barcelona. We flew at 6:00 a.m. with Ryan Air I sat in the middle of the plane, in the window seat.

When we arrived in the United Kingdom we had to show our passaports and then take a bus which lasted two hours more. We arrived at the hotel at about 12 o'clock my frist impression of London was bad the streets were full of rubbish.

The trip started very cold but we went to Big Ben. It was bigger than I imagine. We were very tired because we hadn't slept and finally at night we play poker at the hotel.

We were still tired from playing poker very late. But on this day I saw the best part of th trip, the Natural History Museum. Also at the Museum I remember so many dinosaurs. Later at the Science Museum we played the interactive game.

This morning toke the underground to Camden Town Market. There were many band playing and street foot stalls. I had lunch on the street, pizza and a kebab bread.  There were a lot of people and a lot of different things to see. We arrived at about 11 and we spent the day in Camden.

In the evening, we went to the Musical Charlie and the chocolat factory based on the Story of Roald Dahl. The most impresive thing was that the lead boy actor was only like eleven years old. I understand the show but they did jokes and we couldn't understand it.

Our last day, was a free day so my friends and I went to Chelsea football Stadium. We went to the shop and the official T-shirts were 20 punds. That was strange because in the street they were 40 punds. Because of that we buy some Chelsea  T-shirt. Later we go to a verry big park, Hyde Park and there were so many people doing diferent  sports. Also we went to Pizza Hut and after that, back to the hostel an then home.

In the end, I thought the trip was really good. We did a lot of things in only four days and I spoke some English . The trip was well organised and we liked the fact that we had free time for ourselves as well.

Doctors weigh in on dangers of Wi-Fi signal exposure

We all think using phones and hand-held mobiles is safe. Some doctors think this is not true. 

Children are more at risk because their brain is softer and small so the radiation from mobiles can efect them.

Studies show that radiation exposure can damage health. We know that microwaves can be dangerous but we are realising now that Wi-Fi tablets and smartphones emit signals.

Their is a carcinogenic hazard (cancer). Also memory loss and infertility. For that reason it is imoortant to limit our exposure. We should put the phone and tablet on airplane mod. It can reduce a lot of radiation. Some doctors suggests turning off Wi-Fi at night and using bluetooth

I think that can be true but maybe this doctor is exaggerating the dangers because it can help to develop the illness,bur it isn't the only cause that produces infertility, memory loss... Turning off could help to prevent, but will not be the solution for the illness.

TED talks: Free diving

David Blaine does extreme things that doctors consider imposible. He lived in a cover up coffin one week, he froze herself tree days and tree nights... His next pursuit was see how long he could hold his breath.

He informs about that. He met a top neurosurgeon and he asked him, how long could he go without air? And he said to me that anything over six minutes you have a serious risk of hypoxic brain damage. Also they told him that if he is a magician, he can build up an delusion of not breathing, it will be much easier. David creates a rebreather, but clearly wasn't going to work. Then he thought about the craziest idea of all ideas: to actually do it.

The first thing that he learned is when you're holding your breath, you should never move, because that wastes energy and your heart rate down. Then he learned how hyperventilating because that eliminates CO2 from your blood and that make easy hold your breath. Moreover he starts a diet compoused by small meals.

Afterward of 4 months his heart rate down to 38 and he could hold his breth 7 min. After that, David trys to make slower his heart ratein in extreme conditions due to that he held his breath knot. He lost consciousness and they had to revive.

Finally he decided to do it with pure O2. As well he slept in a hypoxic tent every night. What that does is, you start building up the red bloodcell count in your body,  which helps you carry oxygen bettter. His first attempt on pure O2, I was able to go up to 15 minutes.

For make the tv program he had to tie his foots and do it vertical, because with that way the spector can see David. Normally his hear rate was 38 but in the tv program day his heart rate was 150. After 11 minutes he don't feels his limbs. After 15 min he start to undergo ischemia. However he resist until 17 min 4 s. Finally he reflect about magic and he say that magic is about train and experiment.

I am a amateur of freediving and I can hold my breath 3 min. I am impress about what this man has achieve, but I disagree when he say that he has to learn how hyperventilating. Hiperventilating eliminates CO2, that is true, but so many freedivers don't recommend it because it speed up the syncope and that increments the riskiness.

Connected

Can the Internet make he world a better place? So many people think that is true, in contrast I don't think like them. I think that the Internet can't make the world a better place.

On teh one hand, the Internet means confots because it gives so much information, on the other hand we don't know if that information is true or false.

Also that information gives has facilities and it isn't posible because we haven't to make an effort to search and find the information which we need. Morever we don't check if that information is trustworthy.

In conclusion, I think that the Internet can't make the world a better place because it makes people idle.

My research project

This research project is based on the study of how the conditions of the environment afect human beings.

 For do it I had to compare a whipped habitat with an appeased one to be able to see how affects to the hidrodynamism of the zones as well as algae. Moreover I had to compare morphologic features of the fish depending on the habitat they live in. Acordigly I had to identify and analyze every living being due to I prove the existense of a big biodiversity in Cap de Creus.

My study is based on two transsects. A transsect is a rectangular shapped area where data is collected systematicallt.

GoT: Books vs series

Currently, Game of Thrones is a famous series. That serie is based on the books Ice and Fire. This book came out in 1998. I discovered the history 3 years ago. I started to read the next book because I couldn't wait to saw the next season. That book's called: "Ice and Fire - A feast of crows".

At the beginning I had many dificulties to understand it, because in the book appear so many characters but the history is the same. The differences between the books and the series was very small (in the fist 4 seasons).

The biggest difference is in the red wedding. In the books the girlfriend of Robb Stark escapes pregnant. Because of that so many fans thinks a new Stark will appear, but in the series the girlfriend of Robb dies in the red wedding.

Last year a new season come out which I have read, In that season I found so many differences, principal I found it in the historys of Danerys, Thyrion, Sansa and Marggery. That historys only concide the end because of that this season reacived many complaint.

The delay of Winds of Winter

George R. R. Martin published in his live journal that he couldn't finish his book the publication was delayed and he admitted that the fans of the series will have more information than the fans who are reading the books.

For this reason, they asked if the series was a spoiler for the book. His answer was "Yes in some ways".

This last year the fans who have read the books when he was in a resteurant they saw him abd were critical of him saying "shouldn't you be writing and not eating. Also, the fans said things like "Be careful or you might die before you finish the books". They threatened him.

He defended himself and said he needed to go out to fans conventions and so he didn't have time to write.

I think that the author has to have time to write more chapters because when he does die, he will be remembered for his finished work. We need to give him more time.
