Retrieving the tables ... TECNOLAB

Do you remember those years in which mathematics classrooms were transformed into a myriad of activities to learn the multiplication tables? What a moment!

do not know ... perhaps, is just one personal impression, but I think at the age of seven or eight years, one of the most important things you learn are multiplication tables. Because these numbers aligned and grouped to symbolize the compression of the sum is much more than numbers. Have more representation and symbolism. One of them is that since you are "older." People asks you multiply, you know? And all proud or proud answer, yes, I know to the table ... and add the 6, 7 or table number you are studying at that time. That feeling of discovering the world and entering the difficult concepts, back when you learn to divide by two digits or when you clear the first unknown of your equations. But little by little, it seems to be fading and is fading ...

will not deny that the Fourier Transform studied during my college years (an application that maps to a function f values \u200b\u200b complex and defined in the line, another function g defined as follows :

)

also gave me a joy comparable to that of multipilicar know ... Interestingly, this math is based on a comprehensive ... no longer the sum of very tiny pieces ... Will the amounts compressed something special? Who knows!

But back to the multiplication ... That first time, and that table of 9! This weekend I went to dinner at my parents house in the middle of the field ... And it was in the mountains, my father asked me:

-Irene, You like to explain stories of science, mathematics, technology ... How do you explain your table nine? -

I accepted the challenge and will comment ... I would say that it is adding nine multiply nine times the number selected ...

To which he replied:

"Yes, theoretically I feel good ... but do you want to surprise with a ruler pnemotécnica I found online?! Look, I extend my hands and fingers are going to tell:

• 9x1 = 9 If you shrink the dede pinky of my right hand and fingers accounts still see that I have drawn are exactly 9
• 9x2 = 18 If you shrink the ring finger of my right hand (next to pinky), you'll see that I have a finger on your left and eight to your right, which draws a 18!
• 9x3 = 27 This time shrug the ring finger and I will be the dede pinky and ring finger of the right hand to your left and seven fingers on your right. 27! 9x4 = 36
• lower the rate my right hand and will get 3 fingers on your left and 6 on your right. 36!
• 9x5 = 45 I'll be down your thumb and see 4 and 5. 45!
• 9x6 = 54 This time, shrug the thumb of his left hand and so we will see 4 fingers of my left hand and 5 on my right hand. As you see the reflection, observed 54! 9x7 = 63
• lowering the index finger of his left hand and then see 3 fingers 6. The 63!
• 9x8 = 72 Now it's the turn of the middle finger of my left hand and so we get the 72!
• 9x9 = 81 is the left hand ring which shrinks and so we are 8 fingers on your left and 1 finger on your right. 81!
• 9x10 = 90 Getting off the little finger of his left hand only see 9 fingers ... 9 i 0 ... so I get to 90!

not you think it's great! Thank my parents for their patience in their day, helping me to see the multiplication tables as a fun game, teaching me to read and want to read everything that was written, to be curious and, therefore, to be scientific. Also today I thank you for continuing to support, to continue to surprise me with something so simple such as multiplication tables and week after week you read Newton's Tangerine!

Thanks to them and everyone else because when you share with someone your dreams, love multiplies! Multiply!

Invitation For Father's Death Anniversary

a new proposal to think, feel, look and create

few weeks ago I started a new project called Cornellá Citilab TECNOLAB. Is a course of technology workshops for children aged 7 to 9 years. For 8 sessions will discuss concepts such as ICT , pixels, i virus programs computer or internet codes, among others. To do this we will use different strategies such as documentation, experimentation and creation. Combine activities of plastic, mechanical or real experience.

the first day For example, we understood what was at stake ICT by phone. Also displays the same drawing pixels colors with different strategies: colored pencils, stickers color square one very small square stickers larger mono. Yes, we found that with more pixels would lose definition. Finally, an image processing program helped us to see it live and direct.

The second day we explore what are the programs and computer viruses. And thanks to a set of envelopes and cards to be played and programmed machines programmers. There was a mischievous boy who wanted to destroy us all with his evil orders! Finally, we end up programming in Scratch!

I would also like to promote to be able to state that learned to others and communicate ideas in public. I am of the opinion that in this country, we often forget this point ... And to me, and witty person Farandulera of birth, it seems a mistake. I think we should combine all the senses every time we propose to teach or learn something. Mathematics is important that the hexagons are drawn staves and listen ... It is imperative that the kind of chemical smell hydrogen sulfide, to touch a base or heard the explosion of hydrogen ...

I have to say that every day passing, particularly technology and informatics, cala me a little deeper ... but as I go I go out (like a computer joke) and an outsider I see that some are looking at the screen in front of combinations of red, blue and green ... Let's go! Show the technology and life in all directions. With a little ingenuity, patience, effort and confidence in what we can do it again ... We'll get to talk about computer mice with a screwdriver, a paper and a pen and the Internet.

TECNOLAB

I think can be a challenge. I hope to conquer without a problem ... And comments are always welcome ... Of course, when Eric, a 9 year old boy has already published its own blog ( http://petitreporter.blogspot.com/ ) looks into your eyes and said: - Now I've caught! ... Sure, everything has to be coded! Without a previous program the printer does not know what I write print! - O Lucas arrives at the end of the one-hour class, saying: - Have you already finished? But if you just spent 10 minutes! -. Do you think you can improve security ... but at least it seems to hit a piece of the road, if only in a vague range of this! Now, of all we will improve the definition and decreasing the size of the pixels!

Skin Looks Like Scratches

Miss Mandarin travels at a speed ...

time ago I worked as a teacher of high school students in mathematics, physics, technology and other subjects ... I remember I enjoyed preparing for the examinations and not because they do exceedingly difficult, but because I liked to put custom questions. I think, you could even say that some of my students waited impatiently to read the new statements. I used the names and the boys and girls in class to name the characters of each problem and the possible problems related to their hobbies. For example, if Joan wanted to be a pilot, an exercise in cinematic would Boeing 747 aircraft , for example, driven by Joan. if Felipe, Oscar and Albert liked the music, they found a disk that turned so many revolutions per minute (rpm) in the attic of his grandmother. And so on ...

Why did I tell you? First, because I think it's a good strategy for exams ... Laborious because every time you think about the group you teach, but very constructive. And second, because today I feel like I've been a cinematic examination of live and direct. Miss Mandarin, myself, I'm back to drive! I have set in motion!

The movement is defined as change the position of a body over time on a referral system. This system is a must! If not I have, I can not perceive the movement ... In fact, although it would not cars, in recent years, I moved. I moved on foot, by bicycle I moved, I moved the bus ... And you know how more I moved? Spinning around the sun! But he never noticed ... not me, not you, because our whole system of references, the earth revolved around the Sun ..

Returning to Earth, with our fixed reference system and focusing on the movement, say that this study can be done through kinematics or through dynamics. The kinematics equations of motion studies taking into account the position, velocity, acceleration and time. The dynamics wonders why the movement and analyzes their causes, the forces.

If you build a kinematic problem with the experience of Miss Mandarin could write ...

"Miss Mandarin in a car traveling at 50km / h. It has been 40 minutes behind the wheel. How many meters traveled? "

I recommend that you first pass all variables to the same units .. .
v = 50km / h t = 40min. (1h/60min) = 0'66h
x = V ‡ t x = 33'333km = 33.333m

We kinematics problem of 3 º or 4 º ESO! And the dynamics ... What say? That was Newton who postulated the three most important laws!

1. Newton's First Law, or Law of Inertia: A body maintains its state of rest or rectilinear uniform motion in the absence of forces that require you to change your status. So we know that whenever a body rotates, there is a force!
   
2. Newton's Second Law or the Law of Force: The change of motion is proportional to the driving force print and occurs as a straight line along which that force is printed. This law is usually expressed mathematically as F = dp / dt = d (m ° V) / dt = (dm / dt) · v + m (dv / dt) = 0 + m · a. Ie the force is the change in momentum (mass times velocity) with time and this ends up expressing itself in most cases as force equals mass times acceleration.
3. Newton's Third Law, or Law of Action and Reaction: With every action occurs whenever an equal and opposite reaction: that is, the mutual actions of two bodies are always equal and directed in opposite directions. Thanks to this law humans walked forward and rockets are flying! Miss Mandarin has

traveling at 50km / h through the streets of Barcelona ... We hope that this is not a problem, or cinematic, and dynamic! And that continues to circulate!

What The Strongest Thin Wood

The Mandarin is growing ... Will he be orange?

missing three days to Newton's Mandarin is six months old. During this time, you have been working with me to be getting gradually generate dialogue and debate scientific, technological and human. Thank you!

This cumplemeses post, I want to show the face of La Mandarina Newton. This photo, by Arnor Skuli of Raykjavik, has become my logo mandarin. I would also tell you about the genealogy mandarin :

The Mandarina is the fruit of mandarin . Belongs to the group of fruits called hesperidium and its pulp is formed by a considerable number of segments full of juice, which contains lots of vitamin C , flavonoids and essential oils . It's more like citrus orange , but smaller, more aromatic flavor and easier to remove the skin. Therefore it is considered a most popular fruits. The Mandarin comes from the tropics of Asia , and it is believed that its name comes from the color of the costumes used by the mandarins , rulers of ancient China. In some Latin American countries called China orange.

I joined when mandarins my thanks to Bruno, the protagonist of a reading book that fell into my hands when I was, only 6 years. Bruno had to write an essay about a family member, and elected to his sister. Bruno said that his sister wanted to be surprised Mandarin and her teacher told her that her sister could not be the fruit of the mandarin. Poor Bruno ... poor sister ... She wanted to be ... was ... Dancer! I also wanted to be a dancer for a while ... until suddenly, one day, studying physics at high afternoon ... I realized that in reality would not be a dancer ... I would be Mandarin. I fell like falling

mandarins, and how they might have fallen apples. Newtonian Apples? Yes, the same ... Those apples who popularized the physicist, English mathematician and astronomer of the late seventeenth, early eighteenth century, Newton.

Newton is considered one of the most brilliant scientists in history. The law of universal gravitation was probably its most important and well known. Under this law, the attraction of two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance that separates them. The law of gravitation is responsible for the Earth orbiting around the Sun, the Moon will join us circling around the earth, objects fall to the ground or we can wear earrings. His most prominent is Mathematical Principles of Natural Philosophy . In it, Newton lists the laws that form the basis of the dynamics, or the study of forces. Curiously, Newton was born the same year that Galileo died, the father of modern science and from whom I have spoken briefly in a previous post. Some consider this detail as a symbol of continuity in the progress of the history of physics.

With this curiosity I say goodbye for today. Yes, hoping that the mandarins continue to move even without being orange or grapefruit, which continue to study physics, falls, bodies, strings and the universe, to continue reporting and you will continue appreciating you. Greetings to all and thanks for being on the other side.
