Betrand Russell; "Beauty of mathematics"

"Mathematics, rightly viewed, possesses not only truth, but supreme beauty — a beauty cold and austere, without the gorgeous trappings of painting or music." —Betrand Russell



Bertrand Russell
Bertrand Arnold William Russell, British philosopherlogicianmathematician,historian, and social critic from the XIX-XX century, described mathematics with the quote we have above, and he could not be more successful with this expression. As well as it is described in the introduction of the present blog, mathematics are everything in our lives; but on the other hand, it is difficult to imagine it... then, what could be better than a video showing it? After researching and looking for examples thanks to the media I have, I was able to find a video which concentrates different examples of our everyday life and how it is related to math in just 1:40 minutes. It bring us different examples: Mathematics involved in computers, in our footprint or even in the area of each snowflake.

Then, let´s go straight to the point:


Brilliant, right? The video show us how everything can be calculated using maths; probability of the dice, equilibrium of the top, noise made by the doors of the metro etc... Therefore, using mathematics, we are supposed to "predict" what is happening and what is going to happen, and that is why mathematics are so important in our lives.

Everything around us is Math. Perhaps, we could say Maths is the most useful tool the humankind has; it is used in our day to day for absolutely everything, even though we do not notice it: From the very beginning of each one (our birth), the amounts of products our mother has been taking to have a successful pregnancy were calculated by this tool, and during the rest of our lives, each act we do, (taking a bus, make a phone call or even eating at a restaurant) are possible thanks to the comfort the technology is giving us, which obviously is possible thanks to mathematics.



Therefore, in the this blog I have created, I am willing to show and share mathematics in itself, we different kind of posts, from interviews to videos where I would like everyone to enjoy and understand a little bit more how is math intruding in our world, and why it is that important in our day to day.



"A little bit of history; Calculus"

By definition, "Calculus is the mathematical study of change, in the same way that geometry is the study of shape and algebra is the study of operations and their application to solving equations". But apart from definitions... How come Calculus appeared in our knowledge? Who created it? Who noticed Calculus should be a new branch in this area? To explain these and more questions, we have to return to our past, reminisce those times we did not live in and try to find the logical aspects of calculus, to make it "understandable" for us. This reasoning can be explained with more than one example... For instance, how can we defend a country without knowing its past? or how can we try to solve a problem just by applying "rules and the theory" if we do not even know what are we doing? Therefore, let´s review Calculus and its past.


It can be said that Calculus was mainly created by Isaac Newton and Gottfried Wilhelm von Leibniz. Both of them developed new systems independently, where Newton considered variables changing with time and Leibniz thought of the variables x and y as ranging over sequences of infinitely close values.

Gottfried Wilhelm von Leibniz


During the development of Calculus over the years, not everyone was agree with either Newton or Leibniz´s models; for example, Lord Bishop Berkeley made serious criticisms of the calculus referring to infinitesimals as "the ghosts of departed quantities". This made the community of mathematicians react, and thanks to these "criticisms", new names with new ideas for the development of the area appeared: Cauchy, Weierstrass, and Riemann reformulated Calculus in terms of limits rather than infinitesimals.


Thanks to all these names, we know Calculus as it is in our days, one of the most useful tools we can use.
