Social Lasing model: Can it explain the sweeping power of recent social movements?



A laser is a device that emits a beam of coherent light through an optical amplification process. Components of a typical laser:
  1. Gain medium
  2. Laser pumping energy 
  3. High reflector 
  4. Output coupler 
  5. Laser beam

Optical amplification occurs via the stimulated emission of electromagnetic radiation from excited atoms or another medium. The principle is increasingly applied to explain social changes from color revolutions to such democratically structured protest actions, such as Brexit. The potential combination of information technology and social media to induce social instability is immensely relevant. 
The social laser
We live in the information age. Online Echo Chambers (social resonator) can amplify social mood and intentions to produce coherent information waves of high amplitudes (i.e., huge motivational energy). In real lasers, the optical resonator is an arrangement of mirrors that forms a standing wave cavity resonator for light waves. The Internet-based posting of news and communications works as a multiplier mirror. In this, the mass-media plays the role of laser’s resonator, the optical cavity. The stimulated amplification of coherent social actions can be either destructive or inspire better decision-making. The bandwagon effect in human behavior explains the increasing probability of personal reaction as the power of the excitatory field increases. The homogeneous character of social actions (coherence) and the short time needed for their generation and relaxation can be described by social laser theory. Social energy might be understood as a form of motivation.

The book, "The Power of Joy" is your guide to self betterment





Success is never arbitrary. Our continuously changing world challenges our determination every day. Achievement requires adherence to goals, the ability to take risks, and overcome mistakes. Self-betterment is the ticket not only to a better job but to be successful at it. Changing the mind/brain is like conquering a mountain. Sudden shifts in attitude, behavior, and disposition are challenging and often painful. There is safety in slow, persistent progress. When you trust in the long-term results of your work, you can find balance and satisfaction.

Trying to avoid change is our shared human fallacy. Being near the edge of the precipice effectively triggers human ingenuity. We tend to face our difficulties only when a crisis hits, and the change cannot be put off. Becoming proactive in your approach to life transforms you from passive to an active and purposeful participant. My upcoming book, "The Power of JOY," is a practical guide for self-betterment.

Finding and accomplishing your purpose in life is the highest achievement, and I believe it is possible for everyone. The book introduces techniques for self-betterment. These methods can be practiced by anyone, at any age, and from any cultural, religious, or social background. When you change, you change the world.

I hope you and your loved ones are staying safe during the corona pandemic. Conferences have been canceled, and people furloughed. Those who work in essential industries, hospitals, or food service workers are overwhelmed with the increased demands of their jobs and the desperate need to stay healthy. My modest contribution is the speeded up publication of "The Power of JOY." This small volume might help you maintain your emotional balance and sanity. If you work in healthcare, food service, or other required fields, I am grateful for your contribution. I will forward a free copy to your email address just for the asking: eva.kdeli@gmail.com. Stay safe. And keep working for all of us. People need you, now more than ever.

Are quantum processes relevant in photosynthesis?


Free waves clip art pictures 3 - WikiClipArt





What is "quantum biology"? It is the study of quantum effects in complex biological systems. These studies have a history stretching back to the early years of quantum mechanics. During photosynthesis, light-harvesting occurs on time scales of tens of microseconds. The couplings between the constituents and interaction with the bath will govern the dynamics of the system

Photosynthetic pigments are held up by a protein scaffold. When interacting with light, the pigments do not act as independent units because the transition energies and oscillator strength are distributed within the scaffold. The resulting collective excitations are called "excitons." Coherence is a certain degree of spatial delocalization of the excitations in the system. Excited superpositions evolve in time as damped oscillations with a frequency corresponding to the energy difference between the constituent states. It is widely accepted in science that the dephasing of any interexciton coherences results in sub–100-fs (femtosecond) decay times at room temperature. Energy transfer within the complex is impossible during such a short time. The reaction center of the photosystem shows similarly fast electronic decoherence rates.

The incoherent relaxation between exciton states forms energy transport with downhill in energy. Since these exciton states are partially localized, this relaxation corresponds to hopping between different spatial regions of the complex. The variable site energies direct the energy flow, automatically providing a definite directionality for the transport.

The inhomogeneous charge distribution in the light-harvesting protein complex leads to varying site energies of the pigments. The effect directs the excitation energy toward the reaction center. Suppressed correlations in site energy fluctuations lead to an efficient dissipation of the excess energy of excitons. The absence of long-lived interexciton coherence on relevant time scales makes quantum occurrences impossible. 

In conclusion, photosynthesis occurs on the fastest possible time scales. The dephasing of coherences in biological conditions is too instantaneous to contribute significantly to the light-harvesting function. Are quantum processes relevant in photosynthesis? Quantum coherence in photosynthetic light-harvesting is unlikely.

Sex differences in human lifespan are also true in other mammals




Man and Woman Sign Vector and PNG files - Free Download | The ...


In human populations, women live longer than men. All species mammalian females also live longer than males, but there are no sex differences in the rate of aging. Males and females age at the same degree. Demographic data from 101 species shows that the female’s median lifespan is, on average, 18.6% longer than that of males of the same species. However, the difference is very variable across species, meaning other factors need to be considered to explain this variability. In humans, the female advantage is, on average, 7.8%. For example, nine out of 10 people who live to be 110 years old are female.

Females have two X chromosomes, while males have an X and a Y. The theory is that the extra X in women has a protective effect against harmful mutations and that this holds true in other species. Nevertheless, the cause for the long life of females is probably an interaction between environmental conditions and sex-specific genetic variations. For example, males devote more resources towards specific functions (such as mating, fighting) compared with females. 

There is hope for men after all; the risks of dying are not increasing more in males than females as they get older. Although male mortality is always higher, the rate of dying is about the same in both genders as they age.

Understanding the Coronavirus: The Hammer and the Dance







Adopted from: Coronavirus: The Hammer and the Dance by Tomas Pueyo



The coronavirus is new. We know very very little about it. We have to learn to stop hand-shaking and give hugs. We must open doors with our elbow. We must wash our hands after touching a doorknob. We must disinfect tables before sitting down. Masks can help to avoid infecting other people when we are sick and reduces the likelihood that we get infected. All of these are pretty cheap ways to reduce the transmission rate. The less this virus propagates, the fewer measures we’ll need in the future to contain it.

Strong coronavirus measures today should only last a few weeks, there shouldn’t be a big peak of infections afterward, and it can all be done for a reasonable cost to society, saving millions of lives along the way. If we don’t take these measures, tens of millions will be infected, many will die, along with anybody else that requires intensive care, because the healthcare system will have collapsed.

Is the cosmos infinite or discrete?






Is the cosmic infinite or discrete? Currently, physics cannot decide between the two contrasting views. The answer is related to dimensionality. In mathematics, the number of dimensions reflects the number of independent characteristics you can adjust to the underlying system. In quantum mechanics, every possible position of the electron defines a different state space. Gravity also represents smooth changes in curvature. But information physics shows that there is a limit to the parameters the describe holographic spaces, such as black holes.

Dividing the universe by an information blocking horizon gives rise to a compact energy space, where the wave functions, i.e., particles live. The waves can form fluid-like behavior, such as interference and entanglement. Interference is the combination of ripples on a surface of a pond. Insulation of the wave function unbound the particle from gravity and distance and permits entanglement.

Interference of waves.

Compact dimensions define a discrete frequency for the wave function. The universe is in constant change. Interaction switches the rates of oscillations between the compact dimensions, but it also changes the volume of space. 
Compact dimensions are separated from space top; interaction changes the volume of space around entangled particles. Interaction changes the shape of space and forms the smooth topology of gravity. 



The horizontal lines indicate the compact dimensions. Energy levels are increasing, but frequencies are decreasing from the top toward the bottom. Interaction changes the gravity (S shape) between the poles of the universe (black hole and white holes). 

If the universe is a giant clock, then the compact dimensions form its small hand. Gravity is the big hand, which indicates our distance from the poles (white and black holes); we are located at about halfway between the poles. The answer to the question in the title is both discrete and infinite! Establishing a solution in this question has ramifications for our understanding of the cosmos, for theoretical physics, pure mathematics, and even programming.
