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.
Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.
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.

2. is the Stuff Around You. is everything around
you. Atoms and molecules are all composed
of matter. is anything that has and takes up
space. Everything in this universe is made up of
The air we breathe, the food we eat, the water we drink,
stone, stars, moons, plants, clouds, planets, etc. Are All
Matter.
_______________________________________________
3.
4. is made up of particle/ Molecules/ Atoms.
The particles are very tiny.
The particles of matter have spaces between them.
(Inter-Molecular Space)
The Particles are continuously moving.
The particles of matter attract each other. (Inter-
Molecular Force)
5. Take some water in a beaker and note its level. Dissolve
some salt or sugar in it with the help of a glass rod. The
salt dissolves in the water but the level of water does not
change. This is because the particles of water get into the
space between the particles of water. This shows that
matter is made up of particles.
Matter is made up particles :-
6. Dissolve 2 – 3 crystals of potassium permanganate in
100ml of water in a beaker. Take 10ml of this solution and
dissolve in 100ml of water. Take 10ml of this solution and
dissolve in 100ml of water. Repeat this process 5 – 6
times. This shows that a few crystals of potassium
permanganate can color a large volume of water because
there are millions of tiny particles in each crystal.
The particles of matter are very tiny

8. Take some water in a beaker and note its level. Dissolve
some salt or sugar in it with the help of a glass rod. The
salt dissolves in the water but the level of water does not
change. This is because the particles of salt get into the
space between the particles of water.
The particles of matter have space between them
9.
10. Take some water in a beaker and put a drop of blue or red
ink slowly along the sides of the beaker. Leave it
undisturbed for a few hours. The ink spreads evenly
throughout the water due to the movement of the particles
of water and ink.
The intermixing of two or more different types of matter
Particles of matter are continuously moving
11.
12. Take an iron nail, a piece of chalk and a rubber band. Try
breaking them by hammering, cutting or stretching. It is
more easier to break the chalk, less easier to break the
rubber band and difficult to break the iron nail. This is
because the particles in the iron nail are held together with
greater force than in the rubber band or chalk.
Particles of matter attract each other
13.
14.
15. There Are 4 states* of
Solid, Liquid, Gas, Plasma.
Today we shall be learning about:
i. Solids,
ii. Liquids,
iii. Gases.
iv. We shall be discussing A Little About PLASMA.
Many other states are known |to
exist only in extreme situations,
such as Bose–Einstein
condensates, neutron-degenerate
matter and quark-gluon plasma,
which occur in situations of
extreme cold, extreme density
and extremely high-energy color-
charged matter respectively.
Some other states are believed to
be possible but remain theoretical
for now.
16.
17. Solids have definite shape and volume.
The space between the particles is Minimum.
The forces of attraction between the particles is
maximum.
They are least compressible.
The movement of the particles is very less.
Their Kinetic Energy and rate of diffusion is least.
18. Liquids do not have definite shape but have definite
volume. They take the shape of the container.
The Inter-Molecular Space is intermediate.
The Inter-Molecular Force is intermediate.
The movement of the particles is intermediate.
They are less compressible than gases.
Their Kinetic Energy and rate of diffusion is
19. Gases do not have definite shape and volume. They
occupy whole space of the container.
The Inter-Molecular Space is Maximum,
The Inter-Molecular Force is Minimum.
The movement of the particles is Maximum And Fastest.
They are most compressible.
Their Kinetic Energy and rate of diffusion is maximum.
23. Plasma is one of the four fundamental states of matter,
the others being solid, liquid, and gas.
A plasma has properties unlike those of the other
states.
A plasma is an electrically neutral medium of unbound
positive and negative particles (i.e. the overall charge of
a plasma is roughly zero).
24.
25. When a solid is heated it changes into liquid. When a
liquid is heated it changes into gas.
When a gas is cooled it changes to liquid. When a
liquid is cooled it changes into solid.
E.g.:- If ice is heated it changes into water. If water is
heated it changes into steam. If steam is cooled it
changes into water. If water is cooled it changes into ice.
26.
27.
28. MELTING (FUSION)
When a solid is heated, the particles begin to vibrate
with greater speed and begin to move more freely. Then
at a particular temperature the solid melts and changes
into liquid. The process of melting is also known as
fusion.
The temperature at which a solid melts is called its
melting point. The melting point of ice is 00C or 273 K.
29. LATENT HEAT OF FUSION
The amount of heat energy required to change 1kg of a
solid into liquid at atmospheric pressure at its melting
point is called the latent heat of fusion.
30. BOILING
When a liquid is heated, its particles begin to move even
faster. Then at a particular temperature the liquid begins
to boil and changes into gas (vapour).
Boiling is a bulk phenomenon. When a liquid boils the
bulk of the liquid changes into vapour.
The temperature at which a liquid starts boiling is
called its boiling point. The boiling point of water is
1000C or 373K ( 273 + 100).
31. LATENT HEAT OF VAPORIZATION
The amount of heat energy required to change 1kg of a
liquid into gas at atmospheric pressure at its boiling
point is called the latent heat of vaporization.
32.
33. SUBLIMATION
The change of state directly from solid to gas or from
gas to solid is called sublimation.
E.g. :- If solid camphor or ammonium chloride is
heated, it changes into vapour. If the vapours are cooled
it changes into solid.
35. EFFECT OF PRESSURE ON GASES
When pressure is applied on gas the particles come
closer and the gas changes into liquid.
We can liquefy gases by applying pressure and
reducing the temperature.
Compressed solid carbon dioxide is called dry ice. If
the pressure is reduced it changes directly to gas
without coming into liquid state. So solid carbon dioxide
is known as dry ice.
36.
37. INTERCONVERSION OF THE THREE STATES OF MATTER
The states of matter are inter convertible. The state of
matter can be changed by changing the temperature or
pressure.
38. EVAPORATION
The change of a liquid into vapour at any temperature
below its boiling point is called evaporation.
Evaporation is a surface phenomenon. Particles from
the surface gain enough energy to overcome the forces
of attraction and changes to vapour state.
39. FACTORS AFFECTING EVAPORATION
The rate of evaporation depends upon:
surface area, temperature,
humidity and wind speed.
Increase in the surface area increases the rate of evaporation.
Increase in temperature increases the rate of evaporation.
Increase in humidity decreases the rate of evaporation.
Increase in wind speed increases the rate of evaporation.
40.
41. EVAPORATION CAUSES COOLING
When a liquid evaporates, the particles of the liquid absorb
heat from the surroundings and evaporates. So the
surroundings become cold. E.g. :- People sprinkle water on
the roof or open ground because during evaporation water
absorbs heat makes the hot surface cool.
During summer we sweat more because during
evaporation the sweat absorbs heat from our body making
the body cool.
Wearing cotton clothes in summer keeps us cool because
cotton absorbs sweat and when the sweat evaporates it
