Quantum Field Theory and the Limits of KnowledgeSean Carroll
A seminar, given to philosophers, on how quantum field theory allows us to delineate known from unknown in fundamental physics, and why the laws of physics underlying everyday phenomena are known.
What We (Don't) Know About the Beginning of the UniverseSean Carroll
A plenary talk at the January 2017 meeting of the American Astronomical Society, on whether the universe truly had a beginning, and what might have come before.
Space is not fundamental (although time might be). Talk at the 2010 Philosophy of Science Association Meeting, Montreal. By Sean Carroll, http://preposterousuniverse.com/
This presentation explains about the fate of the stars entering the black hole ,and also it clearly shows the types of the black holes in it, largest star and largest black hole are taken for the example.

15 Mind-Boggling Facts About Black Holes- The Cosmic Enigmas.pdfRiyans
In this presentation, we unravel 15 captivating data approximately black holes, shedding mild on their ordinary nature and the profound impact they have on the material of the universe. In the widespread expanse of our universe, black holes stand as enigmatic cosmic wonders, fascinating both astronomers and space fanatics alike. These mysterious entities, born from the gravitational fall apart of huge stars, have the energy to warp space and time in methods that challenge our knowledge of the cosmos.
1. Invisible Entities: Black holes are areas in area in which gravity is so extreme that nothing, not even light, can escape from them. They are basically invisible, making their detection tough. Scientists regularly rely upon indirect proof, inclusive of looking at the outcomes of a black hollow’s gravity on nearby stars.
2. Formation from Collapsed Stars: Most black holes are fashioned while massive stars exhaust their nuclear gas and disintegrate under their very own gravity. This fall apart can arise after a supernova explosion, leaving in the back of a dense center with gravitational forces so strong that now not even light can break out.
3. Three Types of Black Holes: There are 3 essential forms of black holes: stellar black holes, intermediate black holes, and supermassive black holes. Stellar black holes are shaped from collapsing stars, intermediate black holes have loads among one hundred and 100,000 instances that of the solar, and supermassive black holes, found at the centers of galaxies, may have hundreds equal to millions or even billions of suns.
4. Size Doesn’t Matter, Mass Does: The length of a black hole is defined with the aid of its occasion horizon, the boundary past which not anything can break out its gravitational pull. Contrary to popular perception, the size of the occasion horizon does now not rely on the mass of the item that fashioned the black hollow. A black hole with the mass of our sun would have an occasion horizon of only a few kilometers.
5. Time Dilation: Near a black hole, time behaves differently due to the intense gravitational forces. This phenomenon, called time dilation, method that time passes more slowly for an observer close to a black hole in comparison to a person farther away. This impact has been confirmed through numerous experiments and observations.
6. Hawking Radiation: Theoretical physicist Stephen Hawking proposed that black holes aren’t completely black; they emit a faint radiation now referred to as Hawking radiation. This happens due to quantum outcomes near the occasion horizon, inflicting pairs of debris to be created and one falling into the black hollow whilst the opposite escapes as radiation.
7. Spaghettification: As an item gets towards a black hollow, the gravitational forces grow to be an increasing number of stronger on one facet as compared to the opposite. This tidal force stretches the item into an extended, skinny shape, a manner humorously called “spaghettification.”

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. :)
Astronomers have found dark matter in a variety of environments- Name.docxjames876543264
Astronomers have found “dark matter” in a variety of environments. Name the places where dark matter has been found, and briefly describe how the discovery was made in each case. The question is: In what way is this similar to the construction of Hubble’s law?
Solution
The matter that we cannot observe directly \"dark matter,\". Many evidence are found shows that super massive black hole (dark matter) is located at the galactic centre.
The large fraction of invisible matter is present in the universe because gravity produced by all luminous body is very less compared to amount of gravity required for the stars to orbit around galaxies and the galaxies to their galactic centre.
According to Hubble\'s law all objects appear to be farther away from us.This is possible if the expansion of the universe is accelerating , not decelerating. In order for the universe to accelerate, there must be some force pushing all of the galaxies away from each other, and this force must be strong enough to counteract the deceleration by gravity. Today, we do not know the ectula caue of this. his new mysterious force provided by darks matter, dark energy .
.
Black holes are the most mysterious objects in the Universe. Black holes are huge hungry monsters which even devours light. Yes, even light cannot escape the black hole.

Nucleophilic Addition of carbonyl compounds.pptxSSR02
Nucleophilic addition is the most important reaction of carbonyls. Not just aldehydes and ketones, but also carboxylic acid derivatives in general.
Carbonyls undergo addition reactions with a large range of nucleophiles.
Comparing the relative basicity of the nucleophile and the product is extremely helpful in determining how reversible the addition reaction is. Reactions with Grignards and hydrides are irreversible. Reactions with weak bases like halides and carboxylates generally don’t happen.
Electronic effects (inductive effects, electron donation) have a large impact on reactivity.
Large groups adjacent to the carbonyl will slow the rate of reaction.
Neutral nucleophiles can also add to carbonyls, although their additions are generally slower and more reversible. Acid catalysis is sometimes employed to increase the rate of addition.
DERIVATION OF MODIFIED BERNOULLI EQUATION WITH VISCOUS EFFECTS AND TERMINAL V...Wasswaderrick3
In this book, we use conservation of energy techniques on a fluid element to derive the Modified Bernoulli equation of flow with viscous or friction effects. We derive the general equation of flow/ velocity and then from this we derive the Pouiselle flow equation, the transition flow equation and the turbulent flow equation. In the situations where there are no viscous effects , the equation reduces to the Bernoulli equation. From experimental results, we are able to include other terms in the Bernoulli equation. We also look at cases where pressure gradients exist. We use the Modified Bernoulli equation to derive equations of flow rate for pipes of different cross sectional areas connected together. We also extend our techniques of energy conservation to a sphere falling in a viscous medium under the effect of gravity. We demonstrate Stokes equation of terminal velocity and turbulent flow equation. We look at a way of calculating the time taken for a body to fall in a viscous medium. We also look at the general equation of terminal velocity.
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.

Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.
Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
BREEDING METHODS FOR DISEASE RESISTANCE.pptxRASHMI M G
Plant breeding for disease resistance is a strategy to reduce crop losses caused by disease. Plants have an innate immune system that allows them to recognize pathogens and provide resistance. However, breeding for long-lasting resistance often involves combining multiple resistance genes
7. Dark Matter
Dominant form of mass in Universe
Besides shape of galactic rotation curves, dark matter has not been detected or
identified by any other means
Possible origins: MACHOs, black holes, WIMPS, neutrinos
Dark Energy
unidentified form of energy that caused Universe to increase expansion rate with time
(accelerating universe)
8. Evidence in Our Spiral Galaxy
(Milky Way)
Our galaxy rotates
Based on matter we can detect within our galaxy, there's not enough
mass to keep our galaxy from flying apart because of that rotation....
Unless there's some other form of undetectable matter present to
hold it together
9. Evidence in Galaxy
Clusters
Motions of galaxies in clusters
Gravitationally confined hot gas in clusters
Without dark matter, gravity of cluster would be too weak to
contain hot gas and it would evaporate
Gravitational lensing
Dark matter will distort image of a star or galaxy behind it
10. •2 kinds of dark matter: baryonic kind, like you and
me, and exotic, dominant, non-baryonic kind
•baryonic MACHOs (MAssive Compact Halo Objects)
•nonbaryonic WIMPs (Weakly Interacting Massive
Particles)
COMPOSITION
11. • MACHOs, like their human counterparts, are fairly
mundane: large planetoids, bigger than Jupiter but
smaller than a star, that drift untethered through
space.
• Astronomers have recently detected MACHOs
since their gravity momentarily bends light of
distant stars.
• WIMPs are exotic manifestation of an abstruse and
difficult mathematical theory called supersymmetry
whose existence is barely supported
• WIMPs may be Silent Majority in universe
• So search for WIMPs goes on in huge
accelerators and cold, quiet detectors
COMPOSITION
12. Does Dark Matter really exist?
All evidence for dark matter rests on understanding of gravity.
Possible that theory of gravity is wrong on cosmological
scales?
Maybe, but if you try to explain dark matter with any other
theory of gravity, it doesn’t coincide with masses in solar
system.
So until something comes up that rejects all we’ve known so
far about gravity, dark matter should be taken seriously.
13. The Vitality
Problem: Source of gravity of all stars we can see is
not strong enough to hold them all together so that
mean there must be some invisible rope that lets them
hold on dark matter
15. Food For Thought
There is a Nobel
Prize waiting for anyone
who cares to explain the
actual origin of dark
matter using a convincing
and an experimentally
verified method.
darkBECAUSE we are literally in the
when it comes to dark matter.
