¡Adelante amiga! Y sigue cosechando éxitos como siempre :)
¡Gracias a todxs! Por darme la fortaleza para seguir.
A la memoria de mi abuelo Virgilio Durán (q.e.p.d), quien se mostró siempre orgulloso de mí.

I can do magic too! 
Reverse Arrow Optical Illusion

Look Mah; I can do magic! This is a nice experiment to do with the kids. 

This is simply a demo of refraction: bending of light. #scienceeveryday

The Status of Data in Academic Research.

"There are very few, if any, discoveries each year in academia that come about without building on concepts and ideas that have been previously published in academic journals. This is the natural progression of research. However, this is often limited to building on top of conclusions or ideas, as opposed to the actual research itself. Current dissemination of research is largely based on making available pdf-based summaries of key findings, as opposed to the actual research outputs and raw data behind the graphs. In order to track a diverse array of academic outputs, they must persist on the Internet. One way to do this is via the minting of Digital Object Identifiers (DOIs) by trusted repositories. These managed links overcome the problem of ‘link rot’, which has been shown to occur at c. 10%/year for non-traditional outputs. This article addresses the current problems created by a lack of data sharing in academia. We also look at the incentives structure and potential solutions for improving the quality of academic outputs across all fields of research."

This week I was on a radio program to talk about the new results from BICEP2, which found the first evidence of cosmic inflation.  One of the questions I was asked was about the practical applications of this research.  I gave some mealy-mouthed answer about how cutting-edge research  can lead to new technologies we can’t even imagine, and gave an example of pure research leading to practical applications.  But afterwards, the more I thought about it, the more it became clear that it was the wrong answer.

The question about the practical applications of pure scientific research is a common one.  After all, if society is going to spend money on this kind of work, it has a right to demand some bang for its buck.  Right?

There is some truth to that.  There are times when particular areas of research are funded with a certain goal, such as targeted cancer research, or the development of higher density batteries.  But some research don’t have a goal other than the discovery of new things, and they are a success even if they don’t discover what we expect.  In the case of BICEP2, the project discovered real evidence of inflation.  Even if the project produces no “practical” applications it has been a success, because we now know (assuming the results hold up) that inflation occurred in the early universe.  Not just suspect because it would answer many questions about the big bang, but truly know.  We have more knowledge about the universe than we had before, and that matters.

When someone asks about the practical implications, they take a small view of science.  It ignores the fact that scientific knowledge is itself valuable. Science arises from the innate curiosity that is part of what makes us human.  To do science well requires some of the best aspects of humanity: thoughtfulness, honesty, skepticism, creativity and equality.  It requires us to work together, and it drives us to communicate ideas clearly.  It is a human endeavor that inspires us to do better, and to be better.

It also requires us to look to the future, not just the past.  We invest in scientific research now so that we can make scientific discoveries in the future. The knowledge we gain is not just valuable for us, but for future generations.  By investing in science we are able to bequeath to our children a greater understanding of the universe than we were given. It’s true that pure scientific research will inevitably lead to new practical applications.  It will give rise to new industries we can’t currently imagine. But that shouldn’t be the reason why we invest in science.

Science is a profound act of hope.  It is what a hopeful and forward looking society does. And that’s why we should do it.

Really nice blog post! 
"In fact, if we graphed how abundant all the different elements are in our Solar System, you’d find what appears to be a nice pattern, with some ups-and-downs, but a general curve where the lightest elements are the most abundant, and the abundance of the heavier ones gradually decreases as we move farther and farther down the periodic table.

Or rather that general pattern seems to hold, if you forget about elements three, four and five in the periodic table: lithium, beryllium and boron! These three elements are virtually non-existent in the Sun (or any star), and look awfully peculiar when compared to all the elements around them."

Where do lithium, beryllium and boron come from? Neither the Big Bang nor stars!
