The document discusses the periodic table, including its organization, development, and the information it provides about elements. It explains that the periodic table arranges elements in rows and columns based on atomic number and properties, allowing predictions about undiscovered elements. Each square lists an element's atomic number, symbol, name, and average atomic mass. The periodic table is organized into periods, groups/families that share similar characteristics, and nonmetals, metals and metalloids.
This is a revised PowerPoint on five families of the periodic table I put together for my HS chemistry 9 class after taking a course on visual literacy, inclusive of effective PowerPoint presentations. It could still be much better but I hope some improvement between the two PowerPoints is evident.

Finally we had lovely workshop with the participants trying to find out different ways to think about quality and testing in different parts of the DevOps infinity loop.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

by increasing atomic for what he said were
undiscovered
mass. elements. (Turned
• Put elements in out he was right!)
columns by the way • He broke the pattern
they reacted. of increasing atomic
weight to keep similar
reacting elements
together.

42. Review
1. What can you predict from an element’s location
in the periodic table?
2. To make most synthetic elements, scientists use
powerful machines called ___________.
3. Which group contains the most elements?
4. What prediction did Mendeleev make that came
true less than 20 years later?
5. Fluorine, chlorine, bromine, and iodine are part of
what family?
Although electrons occupy most of an atom’s volume, they don’t account for much of its mass. It takes almost 2,000 electrons to equal the mass of just one proton. On the other hand, a proton and a neutron are about equal in mass. Together, the protons and neutrons make up nearly all the mass of an atom.
Every atom of an element has the same number of protons. For example, the nucleus of every carbon atom contains 6 protons. Every oxygen atom has 8 protons, and every iron atom has 26 protons. Each element has a unique atomic number—the number of protons in its nucleus.
Although all atoms of an element have the same number of protons, their number of neutrons can vary. Atoms with the same number of protons and a different number of neutrons are called isotopes (eye suh tohps).
