Emoticons as a another route of non-verbal communication

I'm going to tackle now something appart from class but has to do with communication: Emoticons.

Back when the first cell phones were made and when Messenger appeared, something new was created: Emoticons. Those are faces that represent people's emotional status. There were two types: On the cell phones, people normally used some alphabetic symbols that readed, looked like a face. For example: :-) . The two dots represents the eyes, the dash a nose and the closed bracket the mouth. That means that person is smiling. On Messenger, on the other hand, were actually faces that were shown when you wrote the legend

They had a huge impact on the new communication devices made in that time, so much that we're still using then those days. Several web pages were made in order to download more emoticons on Messenger and it was normal to find names with emoticons. People always tend to use them to express their feelings, emotions, to write shorter, to be sarcastic or ironic, etc. When you're not facing a person it's easy sometimes to know how are they, but now when using distant communication, so the emoticons are an excellent tool that hans't passed away yet.

Gestures, a vital piece of communication

In this class the secretary didn't prepare the class, so we moved quickly. This day the teacher talked about communication, that not always is the direct language the most important one when it comes talking about anything.

Just like last week, we watched another video, this time of a person giving a speech on a wedding twice. The first time he never made a gesture and was reading the paper's speech all the time. The second time, he was moving from right to left, making pauses, smiling, making a joke, pointing at the married couple... This was an example about how you should make a speech and how not to. In my opinion, is a big difference between the two of them and I realized that is very important to know how to talk in public.

Later, the teacher sent us an activity in pairs. First, we choose a quote from a pdf and tell it to our partner. Then I have to write about how he spoke, like gestures, eye-contact, etc; then we do the opposite thing. Later, we tell a childhood memory and do the same thing with the quotes.

This activity took me 20 minutes to do so.

I'll leave a video so you can see how important is the communication when it comes to give an emotional speech.

First class of Communication Skills

This is the first post for Communication Skills class. Somedays I'm going to write posts about what we do in class.

In every class, some student plays the rule of the secretary, which has several tasks. When the student arrives, he goes to the teacher's desk and pass list. Once it's finishes, the secretary explains what we did the last class in case someone missed the other day. Also, the secretary has to write in the virtual campus a schedule about everything done in the class.

In this class the teacher showed us a video about non-verbal communication  and after that, we reunited in a circle and discuss if we agreed or not. I didn't agree in some parts of the video, like the part that says :"You have to fake a smile and you'll be better". What's the point? That won't fix the problems you've got...
Anyway, after that, we made an activity where we choose the pictures: One of ourself, a nother one from a classmate(both pictures from the virtual campus) and another picture choosed by our own.

This activity took me 20 minutes to do it.

First post

Welcome to the second part of this blog. Now, instead on Calculus, this blog is going to be aimed for the Communication Skills class. I'll be posting several things we do in class, as well as another content. Enjoy.

Interview

Here we have an interview with Pedro Pablo Ortega Massó, ex-worker in General Electric Heatlhcare company. Enjoy.

So what did you study at university and where?

I studied Electronical Engineering al the Laboral University of Tarragona, Spain.

In how many companies have your worked?

I've been working in two companies. Both of them related with the same activity: Healthcare in the diagnostic imaging department.

Can you tell me some of your tasks in both companies?

The first one was "Compagnie General du Radiologie"(CGR). It was a french company that manifactured radiology devices for diagnostic imagin exclusively, from year 1974 to 1984. Along these ten years, I was working in the technical service in charge of the maintenance radiodiagnostic devices of this company as well as ultrasound and digital vascular systems.

The other company was "General Electric Healthcare" (GEH). In 1984 CGR joined to GEH and I was in charge of technical support for Computed Tomography( CT). After five years I started to do clinical applications, helping to the Engineering department to develop tools for diagnostic imaging in CT. After six years I was moved to the Magnetic Resonance imaging (MRI) working in the clinical applications. Eight years later, I started to work in the Marketing and Sales department, finishing my laboral activity as a MR sales specialist.

So, your career's knowledge was very useful in here...

Of course. As I started in a technical department, all my career was very useful and I had to apply all my knowledge when I was working in the field, reparing the different devices as well as developing electrical and electronical instalations.

Did you have to travel in the development of you laboral duties and how often?

Yes, I had to travel along Iberia mainly, but I had to travel to some european countries and Africa to do clinical applications and to the USA to perform some training twice per year.

Did the market keep seeling machines despite the crisis in our country?

The crisis has affected to this kind of companies specially because the social security that is the biggest buyer for this kind of devices has reduced dramatrically the adquisition of this imaging diagnostic devices.

Do you think the market will rise again in a few years?

Fortunately, in the last quartet of the 2014 the market is starting to increase their activity and the operating planning has been risen a 3 % over the expectation.

The Golden Number

When someone says "Maths", maybe the most iconic number they can come up is pi, or rather the e number. But what if there's another number, mucho more important than this other two? Well, it actually exists, and it's called the phi number, also known as the golden ratio.

The value of this number is 1.6180339887 and it represents a proportion between two segments:

The usage of this numbers has been developed by years. Euclid was the first Mathematician who studied the divinal proportion in a regular pentagon and a golden rectangle. By cutting the gold rectangle, it creates a square and a smaller rectangle with the same aspect radio. The most remarkable ones in Mathemathics are Michael Maestlin, who published in 1597 a decimal approximation of the golden ratio, Fibonacci mentioned the numerical series, Johannnes Kepler created the Kepler triangles, a combination of phi along with the Theorem of Pythagoras, and Édouard Lucas gave us the Fibonacci sequence, a numerical sequence.

There are several applications for this peculiar number. Some of them are related to Architecture, painting, design(bookdesign, postcards, playing cards, posters, wide-screen televisions...), music, narute and optimization.

Let's go deeper into the number. This is the negative root of the number, known as the conjugate root

Taking it's absolute value and dividing one by it, we have a new number called golden ratio conjugate.

The golden ratio and the golden ratio conjugate can be expressed like this

Those two expression are used as a scale for every proportion. For example:

The major usages of the number is seen in triangles and pyramids, containing different symmetries.

Monty Hall

Imagine a game show where you’re the participant. You see in front of you three doors: One of them contains a car and the other two, a goat (I think is obvious what the prize is…). The presenter knows which door leads to the car and because he’s a generous guy, he offers you to choose a door. So, you choose one of the doors, but wait, don’t open it yet! The presenter seems to be more generous and opens one of the remaining doors, revealing a goat. Furthermore, you have the possibility of keeping your door, or choose the other one. At this point, is obvious to think the probability of having the car is 50 %, isn’t it? Well…. What if I told you… That statement is wrong?

This problem is known as the “Monty Hall” problem, asked in Parade Magazine in 1990, where Craig F. Whitaker sent a letter to Marilyn vos Savant’s column. The TV program problem’s is a reference to Let’s Make a Deal, a game show where they can’t change their boxes.

So here’s the thing: The presenter knows exactly where the car and the goats are, so he can’t eliminate the door which leads to the car. If the presenter wouldn’t know anything, then we have another probabilistic problem, but that’s not what we’re talking about. We’re talking about the presenter making his decision AFTER the player chooses a door.

When you have the three doors and choose one of them, the probabilities are 1/3 for the car and 2/3 for the goat. So it’s more probable that you first choose a goat and not the car. But either choosing the car or a goat the first time, there will be always a goat that can be eliminated. In that case, the probability of eliminating the car is 0.

So now, we have two doors, one leading to the prize and the one to the failure. Considering the fact that it’s more possible to choose a goat in the first choice, what happens when you change it? That your chance of obtaining the car is higher!
