All good things must come to an end #ChristianoBallondOr

Oh God, what have I done. Thanks to that post title I'm going to sound really arrogant when I say:

This is the last oral presentation self-evaluation! (seriously, say that out loud once)

 

Presentation (10%):

I think I did a good job preparing the Prezi and the bonus video in the end means bonus points... Well, at least I hope you liked the little gimmick, guys.

10 out of 10

Body language & eye contact (10%):

Yep, I do use my body. A lot. Too much. I'm getting a little nervous while watching myself in this presentation... Maybe it's just because I can't stand seeing/hearing myself in recordings... But in my opinion my movements are too hectical.

7 out of 10

Structure (10%):

Well, the structure was quite clear... A small introduction into particle physics so I can explain WHAT neutrinos are, then WHAT makes them so interesting and WHAT are they good for. And curiosities. People love curiosities. Fun facts. Trivia.  
10 out of 10  

Content (40%):

I think the content in itself was solid and I tried my best to explain new and interesting information related to neutrinos without getting too much into complicated and unnecessary details. BUT - and someone remarked that on the evaluation on the 2batspace website, thank you, you were totally right - I didn't mention MY OWN RESEARCH PAPER at all. I did this willingly though. I knew that was the weakness of this presentation, but I prioritised teaching something about the topic in general. Nevertheless, it's still a weakness.

Language (20%):

So, so, so, so, so, so, so, so, so, so.
SO MANY SO'S! SOS! HELP! I CAN'T BEAR IT ANYMORE!
Well, apart from that I guess the language was okay.   
17,5 out of 20

Pronunciation & intonation (10%):

Again, I'm too hectical, speaking too quickly... I thought I got over this. Well, at least I'm warned now. I'd love to do oral presentations without a specific time limit because then I could decide freely by myself about the content. I wouldn't need to cut things out that I consider important for the sake of time and I suspect I would talk more slowly as well.  

7,5 out of 10

Final mark (100%):  10%+7%+30%+17,5%+7,5%=82%   =>  8,2

I must admit, English presentations helped me to get rid of my anxiety of speaking in front of many people. I hated it before Batxillerat. Now I'm quite fine with it.

Exclusive VIP material, don't show it to anyone! Either that one person noticed me as hectical as I do or he/she hates me

And finally, the final script of the final oral presentation of the final round of oral presentations in the final year of English classes in the final year of school which actually coincides with the final year of Batxillerat and now I finally put a final point on this dumb sentence.

Neutrinos

matter = matèria

vacuum = buit (absència de matèria)

Good morning everybody! So today I’m telling you some things hor about neutrinos. Yeah, I also preferred to talk to you about sitcoms and Barney and Sheldon and all these things… So I thought, how to make this presentation at least a little interesting and entertaining for you? I was thinking really hard about it for a long time and in the end I found out that… it’s impossible. So, ladies and gentlemen, make yourself comfortable, please don’t fall asleep (I’m not looking at any specific person), I’m going to start.

Ok, the first big question. What is a neutrino? Can you eat that? Sounds kind of radioactive.

Canvi 3

Well. You know that we are all made of atoms, right? You know that an atom consists a nucleus where you can find protons and neutrons and spinning constantly around the nucleus there are the electrons.

At least I hope that you know this because that’s what they explained to us in ESO, maybe even before of that, I’m not quite sure.

Ok, so this is the smallest form of matter that exists, you know that, right? RIGHT? Yes. Well, actually you don’t know that, because it isn’t.

Canvi 4

A proton, for example, is made up of 3 quarks. And quarks are elemental particles. So, you can say that a proton is formed by smaller particles, but quarks aren’t. I guess, the reason why we never talk about quarks as single particles is because they always appear in groups of 2 or 3 building bigger particles, like protons.

A neutron is also made of 3 quarks, but it’s another combination of quarks, that’s why a proton and a neutron are different.

Alright, so let me see if you can think logically. A proton is made of… quarks. A neutron is made of… quarks. And the electron is made of… (quarks), Exactly! You’re completely wrong! :PPPP

As strange as it might to you, an electron is, in fact an elemental particle, you can’t divide an electron into even smaller things.

Canvi 5

Please have a look at this. You know this one, this is the periodic table, we use this in chemistry and here you can find all the elements that we’ve discovered so far.

Well, this table here is called the „Standard Model of Particles“ and it’s kind of a periodic table for physicists. This is a collection of every elemental particle that has been detected in experiments up to this day. These 6 here are the group of quarks. Here you can see the electron, as I mentioned earlier, another elemental particle. And these 3 right here, are neutrinos. Yeah, I’m sure that now you feel like 5 million times more intelligent than before, right?

Canvi 6

So, the next big question is. Ok, so that’s a neutrino. What’s so special about them?

It’s very simple in fact. There are maaaaaany of them. For every proton, neutron and electron there are approximately 1.000.000 neutrinos. BUT. They practically don’t interact with matter. Every second about 650 billions of neutrinos coming from the sun are penetrating every square centimetre of your bodies. And you don’t even notice it. You’re ignoring them. Poor neutrinos.

Canvi 7

So, if they don’t do anything. What are they good for? Precisely because they don’t interact with matter they conserve a lot of information from their origins. For example, when a star explodes because it has arrived at the end of its life cycle, we also call this a Supernova, it sends off a huge amount of neutrinos. Detecting these neutrinos can help us to determine the energy of the explosion or almost the exact direction of the star. Another thing that is very interesting about them is, that the neutrinos the come from a Supernova arrive at the Earth before the light of the explosion. In other words, if we detect the neutrinos we’ll be able to tell there’s a Supernova before a telescope could see the light of the explosion. Neutrinos aren’t really faster than light, at least not in a perfect vacuum. The reason why the neutrinos get to the Earth earlier is that the Supernovae occur in very far galaxies, so it’s a ridicously long distance that they travel. The particles of light are theoretically faster, but since there is a lot of matter between the Supernova and the Earth, the particles of light interact with that matter on that way, unlike the neutrinos, the interactions with the matter slow the light particles down and therefore the light arrives here after the neutrinos. But the actual speed of the neutrinos is lower than the speed of light.

Canvi 8

In fact, two years ago there was a big debate about this issue. Some scientists measured neutrinos travelling with a higher speed than the speed of light. In the end it turned out to be an error in the measurements. And that’s rather good in my opinion, because if it had been true they would have crashed absolutely everything about Einstein’s theory of relativity. And that means basically, punch modern physics in the face. It’s like telling you after all these years that 2 and 2 make 5 and not four. Yeah, you would all commit suicide immediately.

Finally, I’m about to finish, ok, I wanted to point out some curiosities. Sheldon from The Big Bang Theory works with the stuff I just exposed to you. So if you hear him talking about neutrinos in some episode, think about me, I told you. For the people who think that particle physics isn’t actually important for our daily life, all of your mobile phones, computer and YOUR iPad were, partially, developed thanks to particle physics. So neutrinos and Candy Crush aren’t that much separated in fact.

And the last thing, do we have time? I wanted to show you a video that has nothing to do with neutrinos but with quantum physics in general. It’s just something I found impressive to see.
