OMG, the Earth is flat!!!

Internet has a lot of good things: almost instant communication arround the world, improvement of organization, improvement of business, access to information... But Internet's advantages must be used wisely, because all this potential can be used to a wrong purpose.

One little wrong usage of internet is something called "conspiracy believers", or stuff like this. It's not a big problem compared to other problems of internet, but it's important as well. This is about people that spread rumors or fake information arround internet, based on one idea. They, generally, say that most of thing that we believe are false, that the governments lie to us. Well, this is not foolish, maybe they lie. But things go further and further and they take profit of some usual thoughts of the people, for example that men were never on the Moon. In this example, they add firewood to the fire. But then, they start saying NASA isn't real, and then, what I'm going to focus on: Earth is flat and we live in a lie of the governments!

Well, well... This sound totall crazy, people on the XXI century who believes that the Earth is flat... But they really believe this. Well, some do, others just are looking for money on internet (this kind of publications has a lot of views). They think south pole is blocked by the governments to hide the truth, that all the space images are just virtual, that the Sun and the Moon move just above us... They believe in the Aristotelic cosmovision, of the VI century bC! There are some who follow llitterally the Holy Bible description of the Earth.

And this is how they imagine the Earth. The worse is that people who don't know nothing of science, they can believe all this stuff. Because the human mind, in our society, tends to believe that someone is lying to us. The feeling that you know more than the other people about how is the world, the feeling that you've been wakened up and you know the truth, is a feeling of superiority that we, humans, like. But the ones who start this kind of fake information, they don't even deserve to be mentioned. They are spreading fake knowledge arround the world, to people that have faith on them, and all they say is based on lies and eschepticism. Lying to ignorant people just to earn some money should be punished. They change how people see the world! This is just despicable.

If you don't believe that there's people who believes this, just click here.

PD: I do NOT believe that the Earth is flat. 

2Cellos

Usually every day I spend a lot of time watching videos on YouTube. Well, watching videos and listening to music. The thing I look for on YouTube change drastically, one day I just watch street musicians, the next day all is about the James Webb Space Telescope... Well, few weeks ago it gave me for the cellos, an instrument that, before, I didn't use to listen to. Cellos if played right, make so beautiful music, from the classical to the electric one. 

I found a channel on YouTube that astonished me. It's called 2Cellos, and this is the name of a musical groups composed by 2 croatian boys that, obviously, play the cello. And they play damn good. Their videos are so good as well. In their videos, they usually play classical cellos, but in concerts they use to play electric cello. Here I let you two of their videos:

They have 3 CDs, with covers and their own compositions too. They perform toors as well, and in the shows they use to play well known pop songs, and they have played sometimes with orchestras too.

I like them so much, their way of playing, the edition of the videos with the stories, the funny they are sometimes... And how they introduce the cello to people who just listens pop music, but then, seeing those two boys, maybe starts looking for more music.

Acid base tritation

An acid base evaluation of a solution is a method that allows us to know how much acid or basic is a solution. First of all, it's needed to have a known and trustworthy acid or basic solution, because it's needed to know its molarity.

The acid base titration procedure starts placing the solution we want to study in an erlenmeyer flask. The next step is adding a pH indicator to the solution. A pH indicator is a substance that changes his color depending on the pH of its surroundings. Then, when this is prepared, we start working with the other needed solution, the basic solution. We spill it into a flask and we measure its volume. Then, with a dropper we add this solution to the one we want to study. When the color of all the solution we're studying starts to change, we start adding the basic solution more slowly and carefully, until the color gets fixed. In that moment, we measure how much basic solution we've spent, so we'll be able to calculate how many -OH molecules the starting solution has needed to get to the right pH for the indicator to change of color.

From here, knowing that every -OH molecule neutralizes an acid termination (it's needed to know which acid contains the starting solution) it's possible to calculate how many acid terminations were there in the starting solution. With this information, we just have to apply an easy calculation to find out the molarity of the starting solution that we wanted to study.

Cosmos: A Spacetime Odyssey

About two weeks ago, I heard about a TV series. When I heard about it i remebered a video I had when I was little called Cosmos, hosted by Carl Sagan. In the video, Carl Sagan explained things abouut the universe, and maybe it was the first documentary about the universe that I've seen, the first of hundreds. So I looked for it on internet, and I discovered that on 2014 they published a new Cosmos, so I started to look for more information.

The original Cosmos: A Personal Voyage was started in 1980 and was hosted by Carl Sagan. The show has been watched by at least 400 million people across 60 different countries, and until the 1990 documentary The Civil War, remained the network's highest rated program.

Following Sagan's death in 1996, his widow Ann Druyan, the co-creator of the original Cosmos series with Steven Soter, and astrophysicist Neil deGrasse Tyson created a new version of the series, aimed to appeal to as wide an audience as possible and not just to those interested in the sciences.

So I started to watch the new Cosmos: a spacetime odissey. I've seen four chapters, and I have to say that they are so good. Sometimes Neil explains thing that I know, but even in those moments I don't get bored, because of the way he explains it all. The animatios and the visual effects help too, they had money enough to do it right. And I like too the chronologyof the chapters, and how he explains the live of some scientists who don't are well known even if they did important discoveries. What is even better is the vision of the universe it gives, of history, time, knowledge, faith and science, without avoiding philosophical questions.

The two final nominees

The election of the US new president has been a long process, and on the final elections there were 2 nominees: Donald Trump and Hillary Clinton. Now I'm going to summarize both's strong and weak points:

STRENGTHS

Donald Trump (winner):

• He tells what he thinks directly, and that's what the people want.
• He gives advantages to the main part of the population.
• He focus on make the USA grat again (the American people like that).

Hillary Clinton:

• She's good with the words, she knows how to defend her position.
• She could be the first woman president.
• She is able to build political coalitions.

WEAKNESSES

Donald Trump:

• He's racist as well as xenophobic.
• He doesn't know about political issues, he has no political experience.
• He's unpredictable. What can he do when he's angry?

Hillary Clinton:

• She desn't look trustworthy, it's like she just says what people want to hear.
• She hid things on her campaig, she covers some facts, for example the email's handling.
• She has lied more than once, for example about the attacks of Benghazi.

I think that Hillary Clinton is better than Donald Trumps, and here's why.

I don't care he tells what he thinks directly if what he tells is related with extremist, selfish or racial opinions without showing respect to the other people. Then, even if Hillary has weaknesses too, I think that Trump's ones are inexcusable. In my opinion somebody who can judge differently the people just because of the religion, the race or the sex can't be a good president. But we'll see how he figures out, maybe he'll do well.

Passenger Concert

On sunday 6th of November I met my brother and my sister in Barcelona and we went to Passenger's concert. The concert was in Razzmatazz concert hall at 21:00.

After spending the day arround the city we went to the hall, and after waiting for not less than an hour we finally got there. The hall isn't as big as Palau Sant Jordi, it's quite small, but we were 3000 people there, said Mike (Passenger).

The guest singer was Gregory Alan Isakov, andit wasn't a bad performance, but i didn't like him at all.

Then came Passenger (Michael David Rosenberg) and his band. The concert was incredible, not just because of the singer but because of the audience, there was a lot of energy there.

Singing or talking Mike let us know his opinion about a lot of thing without fear, for example about the government, Donald Trump, XFactor, Hollywood, some famous people, the technologies like mobile phones and sociel networks... I liked that, mainly because I think the same about those things. And the hall was small enough to interact with the crowd.

The concert was amazing and great. The band played song from the last album and from the others. covers too, and in some songs  Passenger played and singed alone. In conclusion, the concert was perfect.

Here is one cover that I liked: The Sound of Silence (Simon and Garfunkel)

The worst thing of the experience was the pitiful returning to Figueres by train at 5:30, with the expectative of having 6 amazing hours in class before reaching home.

SpaceX project: Mars

SpaceX is a private aerospace manufacturer and space transporter company founded by Elon Musk with the objective of sending people to Mars, but to reach Mars they work to reduce the price of sending spacecrafts to the space, basically producing reusable rockets. Nowadays the company has reached some objectives and it's working on improvements.

Elon Musk says the objective of create a colony on Mars is because if we don't expand to other planets we'll extinguish (this is an interesting argument and a great matter to study, different mathematics and statisticians got the same conclusions, one says we have just +/- 1000 years).

“The future of humanity is fundamentally going to bifurcate along one of two directions: 

Either we’re going to become a multiplanet species and a spacefaring civilization, 

or we’re going be stuck on one planet until some eventual extinction event,”

Elon Musk

Until the date SpaceX has been succesful enough to create new and daring projects, as well as continue with his main target: take humans to Mars.

Mars:

On 28th September Elon Musk said that the first manned mission to Mars will probably be on 2024. They'll need more money to devolp the necessary rocket, which will cost 10 billion dollars and would take 100 passengers too Mars. Well, 100 passengers each spacecraft, they plan to send some at the same time.
If all goes right, in 40-100 years there would be a milion people living on Mars. That sounds crazy, completely science fiction, but well, we'll see.

Snowden - film review

The film Snowden is a kind of biographic film of Edward Snowden. It starts on 2013, when Snowden made contact with reporters while he was hid to explain to the world his experience. He starts to explain his career, how he reached his different posts and how he decided to publish NSA's secret and illegal information, mainly the control that the NSA had over the US (for example access to the mobile phone's or computer's cameras and microphones). Then, the movie shows how he escaped and took exile in Russia.

The film is based on the book  "The Snowden files. The inside story of the world's most wanted man", writed by Snowden's lawyer in Russia.

I have to say that for me Snowden is a great film. First of all because the main character: I admire what he did and what he fights for. Then, I like the films that make me think, and in this one you have to, because all the film goes by in security centrals and when two characters talk it's hard to know what they're telling with a clear meaning and what they are telling in figurative meaning. I liked it too because on it there are elements that attract me, for example the world of computers, the laws and how to evoid them, and the real and covered facts.

What I don't like at all is that the film just introduces the story of Snowden, without taking risks or expressing directly what Snowden wants.

There's people who says that the film doesn't show nothing new of the story and that it's just like Laura Poitras' work but shown as a film. I haven't seen Poitras' documents, so I can't say nothing about that.

I raccomand the film to everybody who doesn't knows about Snowden, specially to the people that likes the computing world. It's a good film, it worths the two hours that it lasts.

More information about the film.
