The Engineering of the Roman Army by Jean Claude Golvin

roman army engineering

It is a visually very attractive book, with a large format and very good illustrations. Now, it has made me short in terms of content. roman army engineering is edited by Desperta Ferro Ediciones and its authors are Jean-Claude Golvin and Gerard Coulon.

It is true that both at the beginning of the books and in the conclusions they explain the objective of the book, which is demonstrate the participation of the Roman army in the great public works (which he demonstrates only with concrete examples that I think are not generalizable). Thus, the book, which is divided into the great land works, aqueducts, roads, bridges, mines and quarries, colonies and cities, shows examples of this type of construction in which the participation of the legions is documented in some way.

But everything is very brief, on the one hand I would have liked them to delve into the engineering aspect of the type of construction, since only very general information is given. In this sense the book has disappointed me.


Ali Smith Spring

Ali Smith's Spring, third book of the tetralogy

You can't cry because summer is starting, he says. I could understand that you cry for the arrival of winter. But for the summer?

I come to review Spring by Ali Smith a few weeks after finishing reading it to allow time, for the euphoria to pass and to really see the residue that the book leaves behind… In the end. I publish the review months after reading it and with a calmer vision and having read Fall, the Ali Smith classic. The review is a mix of impressions from months ago and now.

The first thing, although it is a cliché, applies here more than ever. It is not a book for everyone. It is a writing that we could call experimental. It had 70 pages and it was still not clear what the book was about. But I loved it. It's like watching a river make its way.


Lego® Charm | Disney. The Madrigal house and more

The movie collection Disney charm in LEGO consists of three sets. It is ideal for all fans of the adventures of the members of the Madrigal house, Mirabel, Bruno and all the members of this curious house.

Choose the set that you like the most. If you don't have it yet, start with...

The Madrigal house (43292)

The Set recreates the famous Madrigal house from the movie Enchantment on 3 floors. Main element of the film and that we could consider as one more character, since the strength of the Madrigals and their powers lies in the importance of the family, and in this case it is represented by this funny house with magic doors, secret passages and tiles who communicate with Mirabel.


My father and his museum by Marina Tsvetaeva

My parents and their museum by Marina Tsvetaeva

I bought My father and his museum from Marina Tsvietáeva because of a recommendation from Twitter, as well as being from Acantilado, an editorial that up to now has always hit the mark with my tastes.

The truth is that I thought it would deal more with the museum theme and this has disappointed me a little. I love museums and their management fascinates me. We usually go to see museums with the family and recently I have started to document these visits as:

The book is complemented by another volume by the same author entitled My mother and music.

The book consists of 8 short stories. The first 3 written in Russian and the remaining 5, those of the second part adapted to the French taste. According to the publisher, there are 5 very short stories, some barely reaching a couple of pages. They are rewritten anecdotes from long stories.


roman aqueducts

Roman aqueducts and their construction

In this article you will find a lot of information about the Roman aqueducts, how they were built, how the source of origin was chosen, how the route was chosen, etc, etc. These are notes taken from the two chapters on aqueducts of the Roman Engineering series and other sources that I leave at the end.

When many people talk about aqueducts, they think of arches, like those of the Segovia aqueduct, but that is only part of it. The aqueduct is all the channeling from the spring or source of origin to the destination city, and on this journey the water is conducted through different channels, from buried lead pipes, tongue-and-groove rock pipes, channels, rock tunnels, from inverted siphons, decanters, distributors to the arches, everything is part of a great work of hydraulic engineering.

Key elements

The Romans were always looking for sources of great quality and flow. They never supplied water from rivers or swamps to the cities, but from the best springs, bringing water from wherever it was needed.


Crazy about the classics of Emilio del Río

Crazy about the classics of Emilio del Río

Emilio del Río plays Cicerone on a journey through a selection of the ancient classics by great authors of ancient Greece and Rome.

On this trip we will meet 36 authors, their main works and many anecdotes from their lives, the social context in which they lived, who they have inspired and many other interesting facts.

It does not go into depth, each chapter dedicated to an author, is a compendium of references, to his life, his work, his thoughts that prevail today, books and films, authors he has inspired, etc.


Nuclear energy will save the world by Alfredo García

Cover : Nuclear energy will save the world by Alfredo García

Debunking myths about nuclear energy by Alfredo García @OperadorNuclear

It is a very clear and didactic book where Alfredo García shows us the science and engineering foundations behind nuclear power and nuclear power plants.

Throughout the book we will learn how radioactivity works, the types of radiation, parts and operation of a nuclear power plant and the security measures and protocols to follow.

In addition, he will explain the necessary training to be a nuclear operator and will analyze the three major nuclear accidents that have occurred, breaking down the causes, the hoaxes that have been reported and whether they could happen again today.


How to upload files larger than 1Mb to Colab

How to upload very large files over 1mb to google colab

I am going to explain 2 methods to upload large files to COLAB. And it is that there is a problem in Google Colab, or perhaps it is a restriction, that does not allow uploading files larger than 1Mb using its graphical interface.

It is very useful for those who are going to work with Whisper, since any audio weighs more than 1 MB

When uploading a file, it starts to load, it takes a long time and in the end the upload disappears or only 1Mb of our file is uploaded, leaving it incomplete.

I leave you a video

To solve this I will explain 2 methods:

  1. Importing files from Google Drive
  2. With the files library
