The Physics of electromagnetic waves, a discourse to engineering 1st years.
"Lets discover what electromagnetic phenomena are entailed by the Maxwell’s equations.
Electromagnetic Waves are a set of phenomena broadly categorized as “Gamma rays, X-rays, Ultraviolet Rays, Visible light, Infra-red Rays, Microwaves and Radio waves.
We will discuss them from the perspective of Maxwell’s equations."
Classical Mechanics and it’s inadequacies, Planck’s Quantum theory, properties of electromagnetic radiation, dual nature of matter, de-Broglie’s equation, Heisenberg’s uncertainty principle, Photoelectric effect, Blackbody radiation and related laws, Quantum Numbers and its types, Hund’s Rule, Pauli’s Exclusion Principle, AufBau’s Principle or Building up Principle.
The very basic and the most interesting mistakes we are prone to commit when it comes to Physics. From Quantum Mechanics to Gravity, we can be in slippery soil. I have been there, and I want to share a few ideas.
I have tried to keep them very logical and simpler and I hope I get my point across. If any mistakes you spot, direct them back at me. Good riddance.

Electromagnetic waves are an essential aspect of the study of physics, particularly in the realm of electromagnetism. These waves are characterized by their ability to propagate through space without the need for a medium, unlike mechanical waves such as sound waves. At the heart of electromagnetic theory lies the groundbreaking work of James Clerk Maxwell, who formulated a set of equations that unified the phenomena of electricity and magnetism.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
Let's dive deeper into the world of ODC! Ricardo Alves (OutSystems) will join us to tell all about the new Data Fabric. After that, Sezen de Bruijn (OutSystems) will get into the details on how to best design a sturdy architecture within ODC.

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.
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).

Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
15. Section 2:Waves I. Traveling Waves Traveling wave- a fluctuation traveling in some type of matter, AKA medium. They deliver energy from one location to another. Medium - substance that tends to return to equilibrium when displaced(can be solid, liquid or gas). Amplitude - distance from the peak or trough to equilibrium. When it's positive-peak, when it's negative-trough.
16. Traveling waves(continued) Wavelength - distance for a wave to repeat its motion. Measured from peak to peak or from trough on displacement vs position graph. Period - how long it takes a point at a fixed location on a wave to repeat it's motion. To find it on a displacement vs time graph, measure from peak to peak or trough to trough. Measured in seconds. Frequency - how often a certain wave displacement such as a peak, passes by an observer at a fixed location. It’s the inverse of the period. Unit is Hz or cycles per second Wave velocity -found by multiplying the wavelength and frequency. Represents speed at which the wave is propagating through the medium.
17. Traveling waves(continued) The wavelength depends on the frequency and wave velocity. The frequency depends on the wave source. The wave velocity depends on the medium
18. Transverse Waves For a transverse wave, the displacement of the wave medium is perpendicular (think 90 degrees) to the direction of travel of the wave. Light- a true transverse wave. Transverse vibrations of electric charges create light waves. Frequency of light visible to us is between 4x10^14Hz and 7x10^14Hz. In air, light waves correspond to wavelengths of 700nm(red light) and 400nm(violet light). Human eyes are most sensitive to light with a wavelength of 560nm(yellow-green light).
19. Transverse waves(continued) Light waves- wave that can go through a medium but can also go through a vacuum. The wave speed of light in a vacuum is 3.0x10^8 m/s(c). From a vacuum to any medium, light will slow down. The index of refraction, n, relates how much slower something travels in a given medium compared to how it moves in a vacuum. Equation--> n=c/v . the index of refraction (in a medium) is a unitless ration and has to be greater than one
20. Longitudinal waves Longitudinal wave- a wave where the displacement takes place in the same direction. Physically, they are a compression of particles that propagates through the medium. Sound- an example of these waves. It is a fluctuation of density or pressure in a given medium. The more the particles in the medium interact, the faster the wave speed. The speed of sound is 340 m/s. The speed of sound in water is about 1,100 m/s. Humans can hear sounds between 20Hz and 20,000Hz. Sounds under 20Hz-infrasonic. Sounds above 20,000Hz-ultrasonic
21. Wave interference Superposition- addition of the amplitudes of the two waves(AKA wave interference). Constructive inteference- when two waves overlap such that their peaks are at the same position so their amplitudes combine as a result. Destructive interference- when two waves overlap such that the peak of one wave is at the same position as the trough of the other wave at the same time so that the amplitudes combine to make an amplitude of zero .
