This document describes a journey through scales of size from 1 meter to billions of light years and back down to fractions of an atom. It explores scales from the macrocosm of galaxies down to the microcosm inside an atom. The key ideas are that the laws of physics remain consistent across all scales and that there is still much to learn about the universe at both macro and micro scales.
This document discusses the process of using Gherkin scripts to automate acceptance testing over multiple iterations of a project. Key points include:
- Gherkins were used to define test cases and acceptance criteria from the start of development.
- Automated testing was implemented in stages, first manually running Gherkins then gradually automating more test cases across browsers and environments.
- The process evolved to include capturing screenshots, archiving results, and coordinating test execution with various teams.
- Future areas for improvement include expanding test coverage, simplifying maintenance, and generating Gherkins from models.
This document describes a journey through scales of size from the microscopic to the macroscopic. It begins at the scale of 1 meter and increases in factors of 10 from 100 meters to 100 billion light years. It then returns rapidly from the largest scales back to 1 meter. The journey then continues inward in factors of 10 from 1 millimeter to 100 attometers, reaching what is currently known about matter at the smallest scales. The document questions humanity's place and understanding in the vast scales of the universe.

It also addresses challenges such as documentation, traceability, and gaining organizational buy-in for the Gherkin approach.
Google App Engine for Java allows developers to build and deploy web applications without managing servers. It provides services for web apps, data storage, authentication, email, and tasks. While it supports many features, it currently lacks support for custom domains on some services, long-running background processes, streaming, and FTP access. The free account has quotas that refresh daily, including a 10MB app size limit and 3000 file limit per app. The document then demonstrates the App Engine dashboard and tools for viewing apps, datastore, and deploying a Java WAR file.
The document provides tips for documentation design in software projects. It discusses why documentation is important for project success and ensuring all team members understand goals and responsibilities. It also addresses common reasons why documentation is not written or read, such as being time-consuming or not matching the delivered system. The document demonstrates how to generate documentation using a DocGen utility, including building a summary table with hyperlinks to detailed sections for navigation.
The document provides an overview of XML (eXtensible Markup Language). It discusses the need for separating presentation from content that XML addresses. XML allows for structuring and adding semantic meaning to data. It also describes the main components of an XML document including the prolog, elements, attributes, entities, and DTD (document type definition). The DTD outlines rules for the document and enables validation. The document then explains various XML features in more detail such as content models, attribute declarations and types, internal/external DTDs, and entities. It concludes with an overview of the Together Control Center XML editor functionality.

An 8.0 magnitude earthquake struck Sichuan province in China in May 2008, causing massive devastation. Over 32,000 people were confirmed dead and millions of homes were destroyed. However, heroic rescue efforts were undertaken in the aftermath. Soldiers, volunteers, and medical workers rushed to the quake zone to rescue survivors trapped under rubble despite facing dangerous conditions. Ordinary citizens also donated money, blood, and provided other supplies to help with relief efforts. Some survivors were miraculously pulled from the wreckage despite facing tragic losses of family members who shielded them from harm.

This document describes a journey through scales of size from 1 meter to billions of light years and back down to fractions of an atom. It explores scales from the macrocosm of galaxies down to the microcosm within an atom. The key idea is the constancy of physical laws across all scales of size in the universe, from the largest to the smallest.

2. This is a trip at high speed, jumping distances by factor of 10. Start with 10 0 equivalent to 1 meter, and increasing sizes by factor of 10s ,or 10 1 (10 meters), 10 2 (10x10 = 100 meters, 10 3 (10x10x10 = 1.000 meters), 10 4 (10x10x10x10 = 10.000 meters), so on, until the limit of our inmagination in direction to the macrocosmos. Later let’s return, a little faster, up to the point where we started and continue our trip in the opposite direction reducing distances of travel by factors of 10 into the microcosmos. Observe the constancy of the laws of the universe and think about how much the human race still needs to learn...
17. At this height of our trip, we could observe the Solar System and the orbits of the planets 10 13 10 billons de km
18. 10 14 100 Billons de km The Solar System starts looking small...
19. The Sun now is a small star in the middle of thousands of stars... 10 15 1 trillón de km
20. At one light-year the little Sun star is very small 10 16 1 light-year
21. Here we will see nothing in the infinity.... 10 17 10 light-year
22. “ Nothing” Only stars and Nebulae... 10 18 100 light-years
23. 10 19 1,000 light-years At this distance we started travelling the Via-Láctea (Milky Way), our galaxy.
24. We continued our travel inside the Via-Láctea. 10 20 10,000 light-years
25. We started reaching the periphery of the Via-Láctea 10 21 100,000 light-years
26. At this tremendous distance we could see all the Via-Láctea & other galáxies too... 10 22 1 millión light-years
27. From this distance, all the galaxies look small with inmense empty spaces in between. The same laws are ruling in all bodies of the Universe. We could continue traveling upwards with our imagination, but now we will return home quickly 10 23 - 10 million light-years
60. It appears like clouds of electrons... These are carbon átoms that formed our world. You could notice the resemblance of the microcosmos with the macrocosmos... 10 -10 1 Angstrom
61. In this miniature world we could observe the electrons orbiting the atoms. 10 -11 10 picómeters
62. An inmense empty space between the nucleous and the electron orbits... 10 -12 1 Picómeter
63. At this incredible and minuscule size we could observe the nuceous of the atom. 10 -13 100 Fentómeters
64. Now we could observe the nucleous of the carbon atom 10 -14 10 Fentómeters
65. Here we are in the field of the scientific imagination, face to face with a proton. 10 -15 1 Fentómeter
66. Examine the ‘quark’ partícules There is nowhere more to go... At the limits of current scientific knowledge . This is the limit of matter... 10 -16 100 Atómeters
67. And now ...Are you the center of the universe? Are you the special creature of the Creatión? What is behind those limits? Are there any limits? Note that going “downwards” we could only go to the power of minus 16ªof 10 and reached the (known?) limits of matter... But upwards we went to the power of 23ª of 10 and stopped... But really we could have continued our trip with out limits to our imagination!!!! ... then? ...who says that we are alone in the universe?
