Bob Marley & The Wailers - Stir It Up (Live at The Old Grey Whistle, 1973) via @YouTube

I always sense it at the time.. but it’s hard to put your finger on it sometimes you know.

There is always some kind of mocking theme and the jokes on us until we figure it out.

Light absorption promotes an electron in the free radical from its ground state (a doublet state, D0, due to the single unpaired electron) to a higher energy excited state (D1, D2, etc.).

Doublet Emission: The subsequent emission of light occurs as the excited radical returns from the lowest excited state (D1) to the ground state (D0). This is termed "doublet emission" because both the excited and ground states are doublet spin states.

GOD BLESS

In smartphones equipped with quantum dot (QD) displays (QLED), the quantum dots are excited by a blue LED backlight.
The process works as follows:
1Blue Light Generation: The display uses blue light-emitting diodes (LEDs) as the primary light source.
2Excitation: This high-energy blue light shines onto a layer or film of red and green quantum dots, typically embedded within a polymer matrix behind the liquid crystal layer.
3Photoluminescence: The quantum dots absorb the blue photons, which raises their electrons to a higher energy level. As the electrons return to their ground state, the quantum dots re-emit light at specific, pure wavelengths (colors) based on their size due to the quantum confinement effect:
◦Smaller quantum dots emit green light.
◦Larger quantum dots emit red light.
4Color Combination: The resulting pure red, green, and the original blue light pass through the display layers to form the full spectrum of colors seen on the screen.
This method, known as photoluminescence (light excitation), allows for a wider, more vibrant color gamut and greater energy efficiency compared to traditional LCDs that use a white LED backlight with color filters.
In the future, fully emissive quantum dot displays (QD-LED or QDEL) may use an electric current to directly excite the quantum dots (electroluminescence), eliminating the need for a separate backlight, but this technology is still in the prototyping stage.

DIGITAL ID UK ROLL-OUT - SOMEONE HAS MADE A BIG "ERROR" via @YouTube

Quantum dot (QD) biometrics utilizes the unique optical properties of semiconductor nanocrystals to enhance or enable biometric identification systems, particularly for fingerprints and document security. QDs are used in various ways, such as creating high-contrast fingerprint images, enabling advanced security features like spoof detection, and potentially developing novel sensing platforms for biological samples.

•Novel sensing: QDs can be used for more than just fingerprinting.
◦They can act as highly sensitive labels for detecting biological molecules like proteins, DNA, or blood traces.
◦This opens the door to future biometric applications that use biological markers for identification.

OAM (Orbital Angular Momentum) beam jamming refers to the use of intentionally disruptive signals to interfere with OAM-based communication or radar systems

Traditional jamming techniques are less effective against OAM beams due to their unique spiral phase structure, which provides a natural resistance to plane wave jamming. However, sophisticated jamming methods have been developed to specifically target and disrupt OAM signals by generating fake OAM signals, disrupting the mode spectrum, or using frequency-agile techniques.

How OAM beam jamming works
•Targeting the OAM mode spectrum: Jamming signals can be designed to mimic OAM signals, creating fake OAM beams to confuse a receiver's demodulation process.

•Disrupting the phase structure: Some advanced methods optimize antenna configurations to interfere with the spiral phase of the OAM beam.
•Frequency-agile jamming:Introducing frequency agile signals into OAM radar systems makes it more difficult for a jammer to detect and interfere with the signal.
•Exploiting OAM characteristics: OAM's unique power null at the center of the beam can be exploited to either improve security or to generate jamming signals that are highly effective against specific receivers.

How OAM beam systems resist jamming
•Inherent anti-jamming capability: The spiral phase structure of OAM beams is fundamentally different from plane waves, making traditional jamming methods ineffective.
•OAM mode diversity: The ability to carry multiple OAM modes allows for more data and can also be used for error detection and correction, providing a form of anti-jamming resilience.
•Advanced reception techniques: Techniques like Whole Aperture Sampling Reception (WASR) can be used to receive the waveform and validate the mode distributions, enabling the identification and rejection of jamming signals.
•Synthetic OAM: Methods like Orthogonal Frequency Diversity-based Synthetic OAM (OFD-SOAM) can be used to create non-hollow beams that are more resilient to jamming while reducing computational overhead.

I have question… why would anyone for any good reason even put a limit on how far back you look into grooming gang cases?

Why not twenty or thirty years to be absolutely sure regardless and to be thorough?

My first thought is someone wants something covered up that happened over fifteen years ago.

Tony Blair left office as Prime Minister of the United Kingdom over 18 years ago

"Uriel's machine" refers to a controversial non-fiction book by Christopher Knight and Robert Lomas, which presents a pseudoscientific theory about prehistoric technology and cataclysmic events. According to their theory, "Uriel's machine" was a sophisticated astronomical observatory used by an ancient civilization in Western Europe to predict comet impacts and prepare for global disasters, such as massive floods.

For those who think

If the magnetic north pole shifted to Egypt, it would not cause immediate catastrophic physical changes to the Earth's geography. However, it would lead to the magnetic field weakening significantly during the transition, which could cause serious disruptions to technology like GPS and power grids, increased exposure to harmful radiation, and confusion for animals that use the magnetic field for navigation. The planet itself would remain physically the same, as the north pole's geographic location (the axis of rotation) is separate from its magnetic pole
