Stars originate from swirling clouds of gas and dust that condense under gravity to form dense spheres called protostars. As protostars gain mass through accretion, the internal pressure and temperature rises until nuclear fusion of hydrogen begins, forming a main sequence star. Over its lifetime, a main sequence star fuses hydrogen into helium in its core. More massive stars end as supernovae, leaving behind neutron stars or black holes, while less massive stars expand into red giants and later shed their outer layers, leaving behind a fading white dwarf.
This is a self-made presentation about The Big Bang Theory (NOT the TV show :P) to be given to a lecturer and students of University level. Intended for all those to download who may have presentations to give and can't find a good enough topic :). Everyone else is free to download it for other purposes as well!!

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

4. “ Ancient civilizations searched the heavens in wonder and awe.” ZIGURRAT PYRAMIDS STONEHENGE
5. “ Watching the movement of the sun, moon and stars became a way to identify cycles for crop planting & harvesting, celebrating events and marking the passage of time and seasons.” CROP PLANTING HARVEST
6. “ And yet for some, it became a way of worship and seeking their unknown gods.” STARS, SUN AND MOON WORSHIP ASTROLOGY
7. “ But then again, we know far better to worship not the creation but the Creator!” 1 “In the beginning God created the heavens and the earth... 3 And God said, “Let there be light.” 4 God saw that the light was good, and He separated the light from darkness. 5a God called the light “day” and the darkness He called “night” … 14 And God said, “Let there be lights in the expanse of the sky to separate the day from the night, and let them serve as signs to mark seasons and days and years, 15 and let them be lights in the expanse of the sky to give light to the earth.” And it was so. 16 God made two great lights – the greater light to govern the day and the lesser light to govern the night. He also made the stars. 17 God set them in the expanse of the sky to give light on earth, 18 to govern the day and night and to separate light from darkness. And God saw that it was good.” GENESIS 1: 1,3-5a,14-18
10. Stars originate from swirling clouds of gas in deep space located between other stars called the nebulae
11. Mutual gravitational attraction begins to pull particles from the gases into a cluster. The cloud of gas begins to condense eventually forming a dense sphere called, protostar which a has an average diameter of 2.5 million kilometers.
12. Pressure and energy from hot gases due to the increasing fusion reaction begins to balance the gravitational attraction of each particle and a newborn average star begins its stable life.
15. ACCORDING TO BRIGHTNESS AND TEMPERATURE Factors that Affect the Brightness of Stars 1. The amount of light produced by the star 2. The size of the star 3. The relative distance of the star
16. STAR TYPES AND THEIR TEMPERATURE 2 000 – 3 500 Reddish M 3 500 – 5 000 Red orange K 5 000 – 6 000 Yellow G 6 000 – 7 500 White F 7 500 – 10 000 Bluish A 10 000 – 30 000 Bluish B 30 000 – 80 000 Bluish O Temperature (in K) Color Type
18. Protostar Stage Gravity pulls the Hydrogen gases together thus increasing its density, internal pressure and temperature which initiates fusion reaction.
19. Main Sequence Stage Star grows more massive and with increased surface temperature. It uses up its Hydrogen fuel as it shines brighter
20. Red Giant Stage Fewer Hydrogen fusion reactions, less energy is released and the star starts to collapse. Its outer layers begin to expand, increasing its surface area. Amount of radiation decreases and it acquires the properties of a brilliant red giant. What follows depend on how massive the star is…
21. The core of the Red giant is gradually converted into Carbon. The star expands and contract and the outer layer gets blown-off forming planetary nebulae . The remaining Carbon core contracts to form a small, dense white dwarf star until it finally cools into a lump of Carbon in space. *The Final Stage of a Less Massive Star
22. The core of the Red giant is gradually converted into Carbon. The star expands and contract and the outer layer gets blown-off. The remaining Carbon core undergoes fusion reaction producing new elements until the stable atom of Iron is reached. The core collapses from intense heat and pressure due to its massive gravity. It explodes catastrophically forming a supernova. **The Final Stages of a Massive Star (Supernova Stage)
23. END OF A SUPERNOVA Neutron Star Stage The supernova produces a brilliant light that may last for months before it begins to dim. Iron core collapses even further and evolves into heavier elements thus, forming what is called a neutron star .
24. Pulsar Stage A neutron star starts to emit a uniform series of electromagnetic impulses which emit visible light that sweeps through space at regular intervals.
25. Black Hole Stage The force of gravity in the core reaches its limits causing it to finally collapse. It becomes very, very dense that even light cannot escape through it.
