Rutherford's experiment involved shooting alpha particles at a thin gold foil. He expected the particles to be slightly deflected, but instead observed that most passed through undeflected, some were slightly deflected, and a few were scattered backwards. This showed that the atom is mostly empty space, with a small, dense positively charged nucleus at the center surrounded by orbiting electrons. Further experiments revealed protons and neutrons in the nucleus. Isotopes of an element have the same number of protons but different numbers of neutrons, resulting in different atomic masses but the same chemical properties.
In these slides, I covered the following topics with PYQ's of CH-12 (Atom) of class 12th Physics:
-Alpha-particle scattering experiment
-Rutherford's model of the atom
-Bohr model,
-Energy levels,
-Hydrogen spectrum

Lattice Energy LLC- New Russian Experiments Further Confirm Widom-Larsen Theo...Lewis Larsen
In series of different experiments with laser irradiation (sometimes combined with electrolysis) of hydride-forming metallic targets immersed in D2O, Barmina et al. claim to have observed both production and so-called “accelerated decay” of Tritium. If correct, their claimed detection of significant amounts of radioactive Tritium production is an extremely interesting experimental result because over the past 24 years, out of the hundreds of thousands of LENR experiments conducted, literally only a handful have ever claimed to observe Tritium as a measurable nuclear product. In separate very recent publications (2012, 2013), Barmina et al. claim to have developed a theory which can explain all their experimental data; their theoretical approach includes ‘new nuclear physics’ and exotic concepts such as a so-called “in-shake-up” nuclear state that enables production of new bound di-/tri-neutron particles.
Presuming that their experimental data are shown to have been correctly measured and results are successfully repeated by other independent researchers, their reported data provides further confirmation of Widom-Larsen theory of LENRs in a type of laser-based LENR experimental system pioneered by Letts & Cravens (USA) ca. 2002 – 2003.
During the past decade or so, there have also been increasing numbers of experimental reports published in various peer-reviewed journals in which authors claimed to have observed changes in intrinsic nuclear decay rate constants of certain isotopes/elements.
Importantly, there is probably a subset of such anomalous reported data in which experimentalists were blithely unaware of any possibility that LENR transmutations could be occurring inside their experimental systems. In such cases, the measured parameter(s) indicating a given nuclear decay rate, say intensities of a series of gamma emission lines, changes because the isotope(s) producing the gammas being measured has/have simply captured W-L ULM neutrons and been transmuted to other different --- perhaps even stable --- isotope(s); ergo, measured isotopes’ intrinsic nuclear decay rate constants did not really change during such types of experiments. Thus, the long-mysterious “Reifenschweiler effect” could in reality be just conversion of Tritium into neutrons that are captured by, among other things, substrate atoms..

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
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).

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

The atom and rutherford experiment
1. Particles
Constituents of the atom
Rutherford’s experiment
Thursday, 10 November 2011
2. Thompson’s model
Thompson believed that the atom was made by:
• A distribution of positive charge spread over a relatively large
area
• Small negatively charged particles (Electrons) immersed in the
positive distribution
• These electrons are like raisin in a Christmas cake (plum
pudding) and are distributed in a way that the overall charge
is neutral
3. Rutherford’s Experiment
Rutherford shot a beam of -particles to a thin target of gold. He was
expecting the -particles to be slightly deflected by the positive
charge of the atoms of gold. Can you explain why he expected such
an outcome?
The problem was that the positive charge of the atoms of gold was too
spread out (in Thompson’s model) to produce a strong deflection, or
even the scattering backwards of -particles that was observed.
Possible

Impossible
trajectory
4. Rutherford’s Model of the Atom
What did Rutherford observed?
1) Most α-particles passed straight through the foil undeflected
2) Some α-particles were slightly deflected (small angles)
3) Few α-particles were deflected at very large angles or even scattered
backwards
5. Rutherford’s Model of the Atom
What were the implications of Rutherford’s observations?
1) The atom is mainly made of empty space
2) The positive charge of an atom is concentrated inside a very small
nucleus in the centre of the atom.
3) The atom has a nucleus in its centre in which the positive charge and
most of the mass is concentrated
6. The Structure of the Atom
Rutherford’s experiment revealed that the atom was made of a positive
massive nucleus surrounded by electrons orbiting around it.
However, they didn’t know what was in the nucleus. More
experiments showed the whole structure of the atom.
Neutron: neutral particle inside the nucleus of
mass slightly bigger than a proton. Different no of
There is empty space between neutrons for the same element make different
nucleus and electrons. In scale the ISOTOPES of that element
nucleus is a pea at the centre of a
football field.
Nucleon no: given by the sum of no of
+ protons and no of neutrons. Using this no
+ + you can identify the different isotopes of
the same element.
Electron: atomic particle orbiting
around the nucleus with same and
opposite charge as the proton and
mass 1/1800 of a proton Proton: a +ve particle in

Li
the nucleus with mass
similar to neutron
Proton no: it tells the no of protons (and
3
also electrons) in the atom. This no is a
property of the element, so the atomic no
identifies what element the atom is.
7. Sub-atomic particles properties
Mass Relative Charge Relative
Particle
(kg) Mass (C) Charge
Proton 1.67x10-27 1 +1.6x10-19 +1
Neutron 1.68x10-27 About 1 0 0
Electron 9.11x10-31 1/2000 -1.6x10-19 -1
8. Isotopes
Thanks to the mass spectrometer Physicists were able to measure
the mass of the atoms of elements. In this way they made the
remarkable discovery that the atoms of a particular element do
not always have the same mass. What they all have in common
is their positive charge!
9. Isotopes
In other words, isotopes are atoms with the same atomic number,
but different mass numbers. This lead to the search for an
additional subatomic particle that would be responsible for the
extra mass, but have no charge. This additional particle is the
NEUTRON.
Match the terms with the correct definitions.
The number of protons in the nucleus.
Nuclide Tells what element the nuclide is.
Mass Number An atom of a particular nuclear structure.
Atomic Number A nuclear particle
Nucleon Total number of nucleons in the nucleus
10. Isotopes
Circle the isotopes of the same element with the same colour.
That’s right

11. Isotopes
Some elements have a large number of isotopes. Some isotopes
are unstable, which means that they will decay spontaneously
into more stable nuclei by the emission of particles and energy.
However, the percentage of isotopes of a particular element
mined on the Earth is remarkably constant no matter what part
of the World it has been extracted from.
