Sapiens - Part 3

Do you like to make plans? Plans for the weekend, for the night or something more specific like plans for your career. It's a good habit to analyze the worst and the best case in your plans. If you don't do that, you should start doing. Our ancestors weren't tidy and they fell into a trap.

We always try to improve a task to be easier to do. But, if you don't plan it you probably will face unexpected difficulties. This is what happened with our ancestors when they abandoned the hunter-gatherers style of life, to start an agricultural life. 
The wheat's domestication allowed our ancestors to have a static life. They didn't have to walk kilometers to collect corn, fruits or hunt some animal to eat, they just needed to manage their plantations.  However, this changed dramatically their diet and concerns. First of all, their feed consisted only in corn and an animal from time to time. Our ancestors could lose all the food by a nature disaster like drought or grassh…

The End of Eternity

How many times did you thought about travel to the past to change something that you did? I did a lot. However, every time I did it, travel paradoxes comes to my mind.


The end of eternity is a about a group of people that study different ways to make a society lives longer. Well, I shortly described the scientists. Notwithstanding, this time-changing organization is called "Eternity", an organization that was founded "outside time" which aimed to improve human happiness by observing and changing little details in human history. The members are known as "Eternals" and they're responsible for reducing human suffering, at the lowest cost of technology, art and other endeavors. For Eternity to exists, they've to be sure that the creation of travel time do not be deleted by some changes in the past. The circle of Eternity's creation must persist through the time.

The plot of this book, by Isaac Asimov (yeah, I love this guy), is around an Eternal ca…

Sapiens - Part 2

When I was younger I used to eat a lot of candy in my friends' birthday parties. Sometimes I got sick for eating too much sugar, but for me it was worth. Nowadays I enjoy a piece of pie or a chocolate bar as my "candy of the week". However, there's a lot of people who still eat a lot of candy or sweet food. You probably know a few of them, right? Do you know why we eat sweet food like it was our last meal?


This unhealthy habit of eating too much candy is already socially accept among us; obesity cases has also been increasing rapidly throughout the world. You probably already have watched those cake videos with a lot of chocolate and calories, and people praising it like it was an eatable food. Well, if we look to the past, the far past when our ancestors were hunter-gatherers, we can understand a bit of this situation.

Sorry, I'm too hyped with this game.
A long fucking time ago, about 30 thousand years, our ancestors, that lived in the savannas and forests, only …

I, Robot

I'm not writing about the movie. Yes, there's a book and this is another post of Asimov's book recommendation.


This was one of the books that I bought randomly in a book sale. I saw the title and thought, why not? I've never watched the movie but I know that the book is different and the movie just uses the concepts of Asimov's Robot Laws.

I, Robot is a book with a collection of short stories (that are connected) about robots and human relationship. What makes the book different of another sci-fi robot genre, is the defined concept of machine behavior. The Robot Laws or the Three Laws of Robotics or Asimov's Laws is a set of laws that define how a robot must behave. The three laws are:
A robot may not injure a human being or, through inaction, allow a human being to come to harm.A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.A robot must protect its own existence as long as such protection does not…

Books or Audio books? Both.

If you're following me, you know that this blog is a way that I'm using to improve my English writing skills. This was the fun way that I found to study a language and not get boring doing it. But, I need to improve the other skills, listening and speaking. Today, I'll write about a method to improve your listening skills.


Mostly of the people say that read a book and listen to a podcast are a great way to improve your listening skills. They are right. However, generally podcasts are a casual conversation, the people that record it doesn't think about pronunciation, they've a limited vocabulary (as I do) and sometimes the accent isn't easy to understand. I know that are proper podcasts for English students, but IMO they aren't funny or even interesting.

It was for those reasons that I tried to find something that I could combine read and listen in a fun way. This year I discovered the Audio books, I already know that they existed but it never interested me …

Sapiens - Part 1

Do you know how important a cooked meal is?


Biology classes was never my favorite class in high school. I've never been interested in memorizing names of bacteria or plants, perhaps my professors weren't interested in teaching either. However, I was captivated into species evolution, I've tried once to study by myself about this using school books. Did not work. Generally, Brazilian high school books are boring and that time I gave up studying about this.
My interest grew up last years, and this book caught my attention. Why not? Turns out, the book is really great and easy to read.


One thing that ensnared my attention was about cooked meal! Eat cooked meal is such a common thing that I've never thought about the meaning of this. When we began to cook our food? And why? The advent of cooking habit made possible to us eat different types of food, transformed the aliment into something more easy to eat, killed germs and bacteria. Our ancestors could ate healthy food and …

Sapiens - Part 0

The next book that I'll read will be Sapiens by Yuval Noah Harari. In fact, I already began to read it.


The thing is that I don't know if I will write about this book, every impression, every thought about the chapters.. is a little bit hard to write about this, because this book is not a novel or an adventure. I bought Sapiens to understand more about us, the homo sapiens and how mankind has come to where it is. From now on, I'll post about some chapters of the book that made me think a lot and probably some posts about fighting games, coffee, programming, etc.. my life :)
