Hey I'm DIVYA SHREE NANDINI. I'm here with my new presentation on Black Hole. I'm sure you'll find it interesting. well first thing what is black hole- "Black hole, cosmic body of extremely intense gravity from which nothing, not even light, can escape. A black hole can be formed by the death of a massive star. When such a star has exhausted the internal thermonuclear fuels in its core at the end of its life, the core becomes unstable and gravitationally collapses inward upon itself, and the star’s outer layers are blown away. The crushing weight of constituent matter falling in from all sides compresses the dying star to a point of zero volume and infinite density called the singularity." wanna know more about it then come with me. :)
"Black holes are where God divided by zero" - Albert Einstein
Black hole – A region in the space where the gravitational pull is so strong that neither substance nor light can leave this area.

Universe is ultimate scene of curiosity. I am dreaming of roaming in space to the extremes of Universty edge since I have learnt to see up in the sky. I am naive, stupid and not at all any specialist in Cosmology but these are my basic qualifications to ask questions!
Jesus Martinez-Manso from the NSB-Spark Pay team is going to talk to us about infinity and beyond! Most of the Universe is made of dark and scary stuff that is going into our mouths every second (no kidding), yet we know very little about it. In this talk, Jesus will give an overview of cosmic dark sector and explain the basics of how we know about its existence. We will cover topics like dark energy, dark matter, black holes and galaxy evolution.
Atheists often promote the idea that the universe, the Earth, and human beings are not unique or special in any way, but are ordinary, meaningless natural byproducts of indifferent forces of nature. This is sometimes referred to as the principle of mediocrity.
The best refutation of this is the extraordinary amount of fine-tuning of the laws and parameters of the universe that gave rise to human life. In other words, the universe is exactly the way it needs to be for you to be here, but the odds against that happening are staggering. The three explanations for this degree of fine-tuning are: chance, necessity, or design.
In this lecture, I describe the laws and parameters of the universe that are finely tuned for human life and show that design is the best explanation for them.
This is a very broad overview of cosmology. It includes an introduction to galaxies, the large scale structure of the universe, black holes, and the fate of the universe. It is intended for teenagers and up.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
1. Mysteries of our Universe
Sharad B Nalawade
Author of “The Speed of Time”
24 July, 2013
2. The Unanswered Questions
• Why do we exist?
• Is our Universe without any purpose?
• How did this all begin?
• What is reality?
• Do we have a freewill?
• Is scientific approach of reductionism enough?
• What is Consciousness?
• Is our nature designed or accidental?
• Are we alone in the universe?
• Can we reverse time?
3. What is Universe?
A vast region filled up with trillions of celestial objects like galaxies made up of billions of stars,
nebulas, planets, gas clusters, dust and comets. Trillions of stars and other bodies clump
together to form galaxy. Milky way is one of them. Our nearest galaxy is Andromeda.
Galaxies come in different sizes and shapes:
Barred Spiral Galaxy
Whirlpool Galaxy
Ring Galaxy Antenna Galaxy Spiral Galaxy
5. Farthest object in the Universe
The object's light traveled 13.2 billion years to reach Hubble.
The age of the universe is approximately 13.7 billion years. The tiny, dim object is a compact
galaxy of blue stars that existed 480 million years after the big bang.
7. Milky Way Galaxy
Diameter: 120,000 Light Years
1 Light Year = Distance travelled by light in 1 year =
2600 Crore Kilometers
Light travels 311040000 Crore Kilometers to reach
end to end
Sun takes 200 Million years to rotate our galaxy once
Sun is 4.5 Billion years old
10. From Atom to Universe
• http://scaleofuniverse.com/
11. Inside Atom
• All of universe is built from matter particles called
Fermions (ex: quarks and electrons) and force particles
called Bosons and Gluons.
• Whether you end up becoming a stone, flower, star or a
human depends on what force that binds these fermions
together. There are four forces of nature.
• Every atom is a combination of electrons and nucleus
(protons & neutrons made from quarks)
• Four forces of nature: Strong (gluons that bind quarks),
Weak (Bosons - radioactive and fusion reactions),
Electromagnetic force (light/photons) and Gravity
(graviton)
12. Higgs Boson or God Particle
• Higgs Field that provides mass to every other particle
• Predicted to exist 40 years ago
• Discovered in CERN Lab last year
• Sensationalized by Leon Lederman
13. Weird Universe
• Microscopic and Macroscopic Worlds are quite different
• Microscopic World – Atoms, Light, electrons, Energy, Strings, God
Particle, etc.
• Macroscopic World – Humans, Tree, Mountain, Stars, Galaxies
What Science says?
• Sub-atomic particles exists as both waves and particles
• Smallest length is Planck Length = 1.616199 × 10-35 meters
• Smallest Time is Planck Time = 10−43 seconds approx.
• There is no way to find both position and speed of a particle
at the same time
• The whole universe is based on the probabilistic nature
• It is impossible to predict future
14. Physics – Quantum Mechanics
• QM works at the microscopic level
• QM does not follow Newton’s laws
•Sub-atomic particles exists as both waves and
particles
• You collapse waves to particle matter by
“observation” (QM)
• Superposition means an electron or any particle can
exist in all places at the same time
• Entanglement means two particles can
communicate with each other instantly defying speed
of light
15. QM, Consciousness & Free Will
• What is Consciousness? How does the brain create
it?
• Our brain capable of creating ideas.
• Does Consciousness collapse a wavefunction?
• AI subscribes to a computational mind
• Superposition and Entanglement lead to conscious
universe
• Freewill, Chaos, Randomness or Deterministic?
16. What is Reality?
• Universal Connectedness
• Non-Locality
• Many worlds
• Godel’s Incomplete Theorem: “This
statement is false”.
• Is Math discovered or invented?
• Great minds: Srinivasa Ramanujan,
Bernhard Riemann & Kurt Gödel
17. Physics – Einstein’s Relativity
• Relativity works at the macroscopic level – stars, galaxies
• Nothing can travel faster than light
• Time ticks slowly for someone travelling very fast
• Length shrinks in the direction of its motion
• At the speed of light, Time freezes
• Nothing in the universe is at rest
• We all live in 4-D space ( 3-D Space and 1-D Time)
• Space and Time are entwined or merged with each other
• Gravity is nothing but curvature of Space-time
• Massive bodies like Sun, Earth bend space-time around
them
• Accelerated motion creates gravity
• Strong gravitational force slows down time
18. Space-Time
• Time flows from past to the future
• Travelling faster than speed of light will take you back in
time
• Space is not empty but active with particle-antiparticle war
• Space-time has 11 dimensions
• All matter in the universe comes from vibrations of 1
dimension strings in the 11 dimension space-time
• These 1 D strings vibrate and their energy produces particles
like photons, electrons, protons, etc.
• You can create matter out of nothing
• Dark energy is pushing universe and accelerating it
• Dark matter is slowing it down
• Universe will end in Big Crunch due to Entropy increase
The object's light traveled 13.2 billion years to reach Hubble, roughly 150 million years longer than the previous record holder. The age of the universe is approximately 13.7 billion years. The tiny, dim object is a compact galaxy of blue stars that existed 480 million years after the big bang. More than 100 such mini-galaxies would be needed to make up our Milky Way.
