## Amazing math from mathematicians to share with kids

About two years ago I saw this Numberphile interview with Ed Frenkel: One of the ideas that Frenkel mentions in the interview is that professional mathematicians haven't done a good job sharing math with the general public. Although I'm not really the kind of professional mathematician Frenkel was talking about, I took his words to…
Margarita Parra's insight:
"It turns out that there are some fantastic ideas that are out there for kids to see. Some surprising fun I had sharing Larry Guth’s “no rectangles” problem with kids earlier this week (see below) made me want to share some of the ideas I’ve found in the last couple of years, so here are a few examples: (1) One of the most incredible lectures that you’ll ever see is Terry Tao’s “Cosmic Distance Ladder” lecture"

Les recuerdo que ya les había compartido esa fantástica conferencia de Tao.

## 14 Books That Connect Students with Valuable Scientists’ Struggles

A study found that students who read about famous scientists' personal and intellectual struggles do better in their science classes. Librarians helped us put
Margarita Parra's insight:
Algo que Jerome Bruner advierte hablando de la manera en que tradicionalmente se enseña historia: borrar todo lo que hace humano a los personajes. Yo me enamoré de la historia de Marie Curie leyendo "La ridícula idea de no volver a verte" de Rosa Montero. Antes, "El evangelio según Jesucristo", de Saramago, me ayudó a entender y acercarme a figuras míticas (para mí). Enjoy!

## Why logarithms still make sense

Logarithms are a notoriously tricky topic for A-level students to grasp.  Having just about got their heads around laws of indices, we suddenly expect them to blithely apply a new - seemingly arbitrary - list of rules that turn index rules literally on their heads: Some people argue that logarithms are an outdated topic and have…
Margarita Parra's insight:
"Given that logarithms and this logarithmic number sense are such a natural part of how our brains interpret quantities, it makes perfect sense to try and find a rigorous mathematical way to represent and manipulate them."

## Why Zero Is So Ridiculously Important

Zero is a strange beast. It took until the 7th century for it to be explicitly recognized as a number in its own right, when the ancient Indians developed a numerical system that expressed zero with its own symbol. Since the development of this number system, which we still use today, zero has been instrumental in our exploration of mathematics.

## How I Learned the Art of Math [Excerpt]

Mathematician Ken Ono describes how an inspiring mentor helped him redefine his relationship with numbers in this excerpt from his new book, written with mathematics writer Amir Aczel
Margarita Parra's insight:
"Doing mathematics can be a mental voyage to a place where clarity of thought and openness to insight make it possible to see the deeper beauty of a mathematical structure, to enter a world where triumph over a problem depends less on conscious effort than on confidence, creativity, determination, and intellectual rigor."

## Are we alone? Setting some limits to our uniqueness

Are humans unique and alone in the vast universe? This question—summed up in the famous Drake equation—has for a half-century been one of the most intractable and uncertain in science.
Margarita Parra's insight:
"Rather than asking how many civilizations may exist now, we ask 'Are we the only technological species that has ever arisen?" said Sullivan."

## Exploring the Myth of the Scientific vs. Artistic Mind

It’s a stereotype, but many of us have made the assumption that scientists are a bit rigid and less artistic than others. Artists, on the other hand, are often seen as being less rational than the rest of us. Sometimes described as the left side of the brain versus the right side–or simply logical thinking versus artistic creativity–the two are often seen as polar opposites.
Margarita Parra's insight:
"Neuroscience has already shown that everyone uses both sides of the brain when performing any task. And while certain patterns of brain activity have sometimes been linked to artistic or logical thinking, it doesn’t really explain who is good at what–and why."
