Except from not extendibg to relativistic effects, Bohmian mechanics is equivalent to standard mechanics.
In BM the guiding equation contribute to non-locality in Bohmian mechanics.
The guiding equation in Bohmian mechanics contributes to non-locality by establishing that the trajectory of a particle is influenced by the wave function of the entire system, not just local interactions. Specifically, the guiding equation dictates that a particle's velocity is determined by the spatial configuration of the wave function, which encompasses all particles in the system.
It highlights Bells work, saying
This means that changes to one particle can instantaneously affect others, regardless of distance, thus violating Einstein's principle of locality. Consequently, Bohmian mechanics explicitly demonstrates non-local correlations inherent in quantum phenomena, making it a stronger assertion of non-locality compared to standard quantum mechanics, where such effects are often more implicit and contextual
Hello everybody,
for my master's thesis I have conducted a study in which we assessed the pulse wave morphology of the participants during three conditions: 1.) Baseline 2.) After a 30min period of leg heating 3.)with cuffs placed at the proximal thighs in addition to the leg heating, inflated to MAP. The trial was a repeated measures trial and the conditions followed right after one another.
The aim of the study was to find out, if pulse waves reflected at the site of the lower limbs, contribute to central pressure augmentation to a meaningful degree.
I hypothesized, that the augmentation index would decrease during leg heating, as a result of a reduced pulse wave reflection. I thought this to be the case, because local heat stress usually leads to a vasodilatory response to allow for an increase in local blood flow. In theory, this should have reduced pulse wave reflection in the leg vasculature.
During BFR (blood flow restriction though inflatable cuff), pulse wave reflection from the leg vasculature was though to increase, because BFR was thought to mimic a vasoconstriction. This should have led to a higher impedance mismatch and thus, to an increased wave reflection.
However, none of the expected results were found. Virtually no significant change was measured during leg heating. During cuff inflation at the proximal thighs the forward and backwards running pulse waves DECREASED.
Does anybody have an idea on how to explain the reduction in forwards and backwards running pulse waves during BFR?
I am looking forward to any kind of answer, comment or thought regarding this matter. Thank you in advance!
Attached below is the table of the main results.
BLH = Bilateral leg heating; BLH + BFR= Bilateral leg heating combined with blood flow restriction
Many seem to think that the string theory as a theory of everything is dead. It is difficult to see this as we know that strings are related to vibration and waves and they go into everything. The whole of quantum mechanics is built around a mass spring equation. We also know that the world is either free radiation (energy) or condensed radiation (mass). Vibrations and waves are also at the heart of Maxwell equations. The question is if it is possible to modify the present approach of string theory to give it a second life.
Dear colleagues,
I’ve created a video on YouTube simulating diffraction phenomena and illustrating how it differs from wave interference.
I hope this visual approach offers a clear perspective on the distinctions between these effects.
Are there experiments with electrons and the double slit experiment where either slit is closed after an electron has passed through one of the slits? I am checking to see if the wave interference pattern does not occur regardless of what slit is closed.
Hi, I would like to understand how to select the distance D in the array factor formula for two antennas, given by AF=2⋅cos(k⋅D⋅cos(a)). Here, D represents the distance between the two antennas.
In cases where we are dealing with large antennas, whose sizes cannot be ignored (unlike simple dipole antennas), how should we define D for the array factor?
For instance, if the sizes of the two antennas are approximately ten times λ0, should we consider D as the distance from the center of one antenna to the center of the other (for example, 40⋅λ0), or should it be measured from the edges of each antenna?
If I consider D as the distance from the center of one antenna to the center of the other, they are approximately isolated from each other and their patterns are seperate. However, the plane wave could be a combination of the two patterns, making the array factor somewhat meaningless. Am I correct in this assessment?
As you can see, the array factor for the distance between the two antennas is completely different.
Macro Coherence refers to the application of quantum decoherence principles to the macro realm. It suggests that multiple potential realities in the macroscopic world stabilize into a singular, observable one, similar to how wave functions collapse in quantum theory. This concept implies that, much like in quantum systems, the possibilities in the larger world 'solidify' into a single reality as coherence is lost, giving rise to the observable universe.
I wonder whether it is reliable to conduct an imputation of full scales/questionnaires in our study.
We conducted a longitudinal data collection of 3 waves. There's a time of 3-4 years between each wave (wave 2 was collected 3 years after wave 1, wave 3 was collected 3-4 years later after wave 2). However, some participants collected in wave 3 left some of the questionnaires unanswered, which means that those answers are missing.
Something important to add is that all the participants of the three waves were emerging adults, which means the participants are undergoing numerous and significant personal, social, work-related, and other life changes over the years (and wave 2 was collected during Covid lockdown). Longitudinal analyses between waves 1 and 2 have shown that the relative stability of most scales and subscales ranges from 0.3 to 0.6, which is not especially high. Additionally, some participants were not present in wave 2, meaning that the data we have for the imputation of the responses of these participants would come from only one collection. Is it methodologically reliable to impute responses to entire questionnaires based on the responses provided by those same participants in previous waves to those same questionnaires? (and given the characteristics of the developmental stage in which they are). And, if it is possible, which would be the more robust methods to do so?
Figure 1：
① First, by inputting hourly wind speed and tidal level data for a specific location over the course of a month into the model, I simulated the hourly wave heights. However, the model initially produced wave heights that were significantly higher than the observed values. Therefore, I would like to ask which parameters can be adjusted to fine-tune the model locally?
②Since one set of parameters cannot be applied to the entire calibration period, how can suitable calibration data and periods be selected? What factors should be considered to ensure the safety and reasonableness of the design wave height for the project?
③During calibration, is it possible to use different model parameters for different situations?
Figure 2：
④After that, I used wind field data from the ERA5 database, processed it into a DFS2 file, and applied the model to the site. However, the model results were very unreasonable, showing wave heights only during periods of high wind speed. What is the reason for this?
⑤Finally, when there is a situation where the model calibration results are good but the design wave height is excessively high, how should this generally be handled? How can the reasonableness of the design wave height be assessed?
Hello,
I am having a difficult time finding the incident plane wave wavelength dependent spectra of the lights source to find the EQE.
Please advise.
I am trying to design a Circularly Polarization reflective metasurface. I want to know , how to Get the accurate circularly polarized reflection parameters when I try to illuminate the unit cell with a circularly polarized excitation wave. I set one Floquet port having two modes, 90 degree out of phase from each other. After simulation, I am able to plot the (FloquetPort1:1,FloquetPort1:1); S(FloquetPort1:2,FloquetPort1:2); S(FloquetPort1:2,FloquetPort1:1); S(FloquetPort1:1,FloquetPort1:2); But they both seem to represent the linear polarizations. How to get the circular polarization, like S(RHCP,LHCP);S(LHCP,LHCP). Is there any formula to calculate it? Thank you.
Combined Equation for Macro Coherence
\Psi(x, t) = A \cdot e^{i(kx - \omega t)} \cdot f(\rho, T, \Phi)
Where:
: The wave function representing the state of the macroscopic system over space and time .
: Amplitude, indicating the probability density of emergent structures.
: The oscillatory part of the wave function, where:
: Wave number related to the spatial distribution of matter.
: Angular frequency related to the evolution over time.
: A function that captures emergent properties based on:
: Density of matter (including dark matter).
: Temperature, reflecting thermal dynamics.
: Gravitational potential, accounting for large-scale interactions.
Probability Index for Emergent Structures
To derive the probability of emergent phenomena, we can include:
P(E) = \int |\Psi(x, t)|^2 \, dx = \int |A|^2 f(\rho, T, \Phi) \, dx
Feedback Mechanism
Incorporating feedback into the system:
\frac{d\Psi}{dt} = -i \left( H \Psi + \int F(x) \cdot \Psi \, dx \right)
Where:
: Hamiltonian operator representing the energy dynamics.
: Feedback function describing interactions between emergent properties.
Summary
This combined equation seeks to unify the concepts of wave function collapse, probability, and emergent properties within a macro framework, offering a foundation for modeling and predicting macroscopic phenomena influenced by quantum principles.
I need this program to do some studies and graduation projects for students
I am currently using ANSYS Fluent to simulate regular waves, such as Stokes first and second-order waves, as well as Airy wave theories. While I have input parameters like water depth, wavelength, and wave height, the resulting surface elevation versus time plot does not appear as a regular wave. Instead, it shows unusual peaks and troughs, which differ significantly from the expected wave behavior. Any guidance would be greatly appreciated.
In quantum mechanics, the wave function collapse describes how a particle's uncertain, probabilistic state solidifies into one measurable outcome upon interaction or observation. But what if we could extend this concept beyond the quantum realm, applying it to the macrocosm? This thought experiment proposes a revolutionary idea: just as quantum particles exist in superpositions until a collapse occurs, could reality itself exist in a kind of cosmic superposition, solidifying into the version we observe through large-scale processes?
This opens up a fascinating question: what if the macrocosmic collapse of reality could be reversed, revealing hidden layers, alternate timelines, or parallel worlds? Let’s explore several key ideas that could extend this quantum principle to our universe at large.
I was thinking about how elements on the periodic table... Metals never act as non metals and non metals never act as metals... But under the right conditions semiconductors can act as both even though they possess one characteristic initially... What if quantum objects are actually neither particles nor waves but actually something "in between" which is why they can exhibit both characteristics at the right conditions
A corpuscle can be considered as a packet of waves which reiforces each others in a limited region of space and destroys each others away. The limited region of space what is its length? Is this the length of the packet of waves which form the corpuscle?.
The Relativistic Doppler effect has been explained and derived from the invariance of the wave equation in the case of light (or from Lorentz Transformations). In relativity, it was described as a phenomenon involving two different inertial frames, a consequence of Lorentz invariance.
Other simple methods have been used to give account to the Doppler effect for waves in acoustics.
Acoustic waves in material media, on the other hand, are neither Galilean or Lorentz Invariant.
It was considered so far that the wave equation in EM interaction is the same for the moving source and moving observers.
The Longitudinal Doppler effect in Nature is a detection of a frequency shift of oscillations originated by a transfer of a net energy and momentum due to non stationary positions of Emitters and observers.
It is properly obtained by adopting the conservation of energy and momentum of waves and matter interacting.
The Doppler Radar unveils a potential issue if one considers inertial both RADAR and a mirror, unless placing some external pressure, to a mirror of finite mass, which exactly counterbalances, the radiation pressure.
It is very interesting also that, according to a very recent work by Hrvoje Dodig,
the wave equation for stationary observers and sources cannot have the same form as the one for moving sources or observers for example.
Such feature should be related also to the fact that ENERGY AND MOMENTUM variations are involved and they play a role which may not preserve the wave equation form
Other questions are related:
I think it is clear physicists do not understand the symmetry of time independence on the string.
Time independence is a marvelous property that can be stated in a large number of equivalent ways. I am hoping one of these statements will trigger a physicist into understanding what string rigidity means.
1) The string obeys the Hamiltonian principle of least action.
2) The string conserves potential energy in a closed system.
3) The string is rigid, not elastic.
4) The boundary condition on the string is 𝜟x = 0, not 𝜟x ≧ 0.
5) String symmetry is time independence, and the standing wave does not depend on time.
6) String mechanics are naturally symplectic.
7) The string manifold is smooth with a natural tangent-cotangent vector field on the real coordinates of the string line.
8) The fundamental mode is the 1-periodic Hamiltonian solution, and frequency is an extremal that measures the volumetric capacity of the string manifold.
9) The motion of n points on the string creates n world lines that are holomonically constrained to those lines in Euclidean space along which energy is conserved.
10) Let x:ℝ → ℝ3 be a motion in ℝ3.The graph of this mapping is a curve in ℝ x ℝ3.
11) The string submanifold is a complex toroidal disc.
12) The string has a natural Liouville integral on the submanifold.
13) Perturbation theory applies to string mechanics.
All of the above statements are true.
The following statements are all equivalent to the assumption of time dependence which I am intentionally stating in a way that can be seen to be false.
1) The direct observation of trigonometric wave forms on an oscilloscope based on the transduction of sound waves and reflected light emitted by the strings into an electrical current proves the string action is explained by a partial differential equation (PDE) where the world lines of motion are embedded in the arbitrary plane of the oscilloscope screen.
2) The equation of motion on the oscilloscope is given by the PDE is “Let x:ℝ → ℝ2 be the planar motion and the graph of this mapping is a curve in ℝ x ℝ2 which parameterizes a planar graph by time like the oscilloscope screen but is not symplectic and cannot form a smooth manifold.
3) The boundary condition on the string are fixed endpoints and there is no limit on how much the elastic string can stretch (without an external force).
4) A string can vibrate in many, possible an infinite number of modes in the space of simultaneous events without violating energy conservation.
5) Potential energy is not defined on elasticity.
6) Modes of string vibration are sine waves equipped with an addition function on displacement allowing nodes and waves to add without violating natural law.
7) The string can bend and stretch into any shape during vibration without external force or internal constraints.
8) The standing wave is not really standing because it alternates phase with each cycle.
9) Kinetic and potential energy are exchanged like a pendulum.
10) Frequency is proportional to velocity, not potential.
11) Waves on the string propagate left and right, reflect at boundary endpoints and combine to make a standing wave that moves.
12) The standing wave stands down when the string comes to rest like a pendulum where potential and kinetic energy have run down to zero.
13) String frequency and amplitude are not determined by the same equation.
Amplitude decay seems proof the string is time independent. But decay is not independent of time if it follows a curve that is cycloidal (tautochrone) because then the interval of amplitude decay is always the same regardless of how much the string is accelerated.
The equation of motion controls the minimization of kinetic energy.
It might seem that we are required to know the acceleration of the string but in classical mechanics this is not true. How hard the string is plucked does not affect motion.
The Fast Wave package I developed for calculating the time-independent wave function of a Quantum Harmonic Oscillator now includes a new module for arbitrary precision wave function calculations. This module retains the functionality of the original but utilizes Python’s mpmath (https://mpmath.org/) package to control precision. Check it out: https://github.com/fobos123deimos/fast-wave/tree/main/src/fast_wave
Hi,
I have a rectangular waveguide(WR90) that operates at 9.6 GHz. Its guided wavelength is approximately λ_g = 42.34 mm, and the length of my waveguide is L = 950 mm.
Calculation of S21 Phase
According to my calculations, the S21 phase should be: Δφ = ((2π) / λ_g) × L = (360° / 42.34) × 950 = 8077° Since the wave cycle is 360°, I removed all multiples of 360°, so: Δφ = 157.46°
However, the CST simulator shows an S21 phase of approximately -175°. Because the phase in CST varies between -180° and 180°, -175° is equal to 355°. So they are different.
what is my mistake?
Could fuzzy logic be applied to quantum weak measurements as new approach to provide a probabilistic global measurement and thus avoid the collapse of the wave function? In other words, could weak measurement devices be equipped with AI fuzzy logic to collect the minimum amount of data on the quantum system ?
We assume that the Schrödinger wave equation,
iℏ(dψ/dt)= Ĥψ. . . . . (1)
is incomplete and cannot be considered a unified field theory.
on the other hand, its square,
d/dt)partial U= D Nabla^2 U+ S. . . . (2)
Where U=Ψ^2=Ψ . Ψ*
and S is the source/sink term (extrinsic or intrinsic).
is more complete and more eligible to be a unified field theory.
Over the past four years, Equation 2 has been successfully applied to solve almost all classical physics situations such as Poisson and Laplace PDE, heat diffusion equation, and quantum physics problems such as quantum particles in a well of infinite potential or in a central field.
Additionally, Equation 2 has also been shown to be effective in solving pure mathematical problems such as numerical differentiation and integration as well as the sum of infinite integer series.
Finally, Equation 2 was applied to shed light on the mystery of the formation and explosion of the Big Bang.
Hi,
I am trying to simulate a ship in a canal. The top width of the canal is 20m, bottom width is 6m, depth is less than 5m. Ship has a length of 11.7m breadth of 4m, draft is 0.62m. The velocity of the flat wave is given as 0.4m/s. Froude number is less than one (0.057). I am getting revered flow at times in the outlet, it vanishes as the simulation runs. I changed the pressure outlet to outlet condition to avoid reversed flow but the drag am getting is the same and its about 30N as it converges. But the problem is I am not getting proper wake effects (kelvin waves) in free surface. The software I am using is STARCCM+, K epsilon, implicit unsteady, VOF, DFBI are involved in the simulation.
Thanks in advance
I performed P and S wave velocity tests for cylinderical limestone and dolomite core samples for dry, staturated (for natural and acid solution treated samples). I expected the P and S wave velosity will decrease for saturated natural and acid solution treated samples but the result was the reverese.
Let's say we have a standard, regular hexagonal honeycomb with a 3-arm primitive unit cell (something like the figure attached; the figure is only representative and not drawn to scale). The bottommost node is taken as the source of wave input and the ends of the left and right arms are taken as destinations such that Bloch's condition can be applied as qleft = eik1 qbottom and qright = eik2 qbottom. I wish to learn how would an iso-frequency contour plot be plotted post performing the dispersion analysis. Thanks in advance.
I want to develop the figure like attached figure. How can I get, peak period and significant wave height at any given location.

Knowledge of properties of illicit drugs in the microwave/low frequency parts of the millimetre wave band (10 GHz to 50 GHz) may at least enable a first line of defence in security screening of people. There's quite a few papers on signatures of these substances at higher frequencies (>300 GHz to 10 THz), where spectral features might be used for chemical identification. However, in the lower frequency part of the millimetre wave band, and microwave band there does not appear to very much information at all. So would anyone have any references to measurements in this lower frequency range?
It would also be useful to know about accurate and validated surrogates for illegal narcotics in the 10 GHz to 50 GHz band. So could anyone suggest surrogates for these materials, or at least papers on surrogates, as this would greatly ease measurements on these materials to investigate capabilities for security screening of people who might be carrying these substances?
Hi All,
I have used infinite elements in Abaqus to absorb waves at the sides and bottom boundaries of the soil domain. but the boundary reflected wave can not be completely absorbed on the boundary.
Does anyone have the similar problem? How to deal with it?
Thank you very much.
Photo-electric effect
A light particle moving towards a surface cannot (by collision) force an electron particle to move away from that surface.
A light wave can instead make interference with a bound electron and thereby force the electron to escape, and this process is reversible, so electrons cam also be captured by atoms and generate waves. Capturing electrons can generate X-rays.
Compton effect
This effect can be explained by light waves absorbed in an electron escape and later emitted in an electron capturing. Two processes with secondary emission of longer wavelength. Longer wave length means: not a scattering process.
Waves can explain everything and particles for light are not needed.
Einstein did not understand the photo-electric effect.

I have found an EEG where only alpha waves are present. Beta waves are not found in active patients. What interpretations ?
Hello,
I am using the Wavewatch III model for my research . Could anyone clarify if it's possible to extract wind wave and swell parameters separately from this model?
Hello, I need some help with analyzing the ABR (auditory brainstem responses data) of mice. However, I am confused that on which basis should I take wave as wave 1?
there are two scenarios,
1- Is there any specific range for wave 1 amplitude (in microvolts) to consider it as wave 1?
2- Should I take the very prominent wave in the ABR waveform as my wave 1 every single time?
Please provide me with the guidelines or any standard method to deduce wave 1 in the ABR waveforms.
I will highly appreciate your guidelines.
Thank you very much.
Hi guys,
I am trying to simulate a 1 ps long plane wave propagating in a dispersive material, with the wave optics transient module. According to the drude-lorentz model, when the frequency of pulse approximate the resonance frequency, this frequency component should have a very low group velocity and basically just oscillate around the input interface. But COMSOL doesn't give such results. Can anyone explain why? I am using the 'drude-lorentz-media' example from the wave optics module. Thanks!
I am working on some .edf files.
I try to extract the frequency distributions from the EEG waves.
The thing is, which i can't be sure if it is a problem or not, the most dominant frequency appears to be 0.39 hz always.
I can remove/change it with bandpass or other filters, but i am not sure if i am missing some important point here.
I used to work on patch-clamp data and this is my first time working with EEG data, just checking the waters for a possible collaboration. I can't be sure if this 0.39 hz is a noise, or something that i do wrong, or is it just how Welch - Fourier works.
I just have the common knowledge that the common low frequency delta waves are 0.5-4 hz and that makes me think. But also, i see on various papers on the internet that the lower-low frequences seems to have a similar peak.
I am sharing single position EEG data from 4 different recordings, although all positions have the similar peak at 0.39 hz. Fs was 200 hz.
Matlab code:
win = hamming(1024);
nfft = 1024;
noverlap = nfft / 2;
[px, f] = pwelch(waveseq, win, noverlap, nfft, Fs);
plot(f, 10 * log10(px))...
How to plot like attached figure in matlab?..

Hi, I performed a simulation of a Transmitarray structure with an impinging plane wave, designed to direct the output beam at 20° right with respect to the axe perpendicular to the structure.
But processing the results, it seems that at the output there are both the contributions of the incident plane wave and the desired beam. How just the scattered field can be obtained?
How these waves form in such a superthermal plasma environment
According to my classical calculations, the whole universe is based on waves.
There is no particle without waves. Even light particles are completely waves.
Waves and matter are always together. Waves create particles. At the same time as the particles are created, other waves are also created inside the new particles. Again, newer particles create newer waves as a result: and this continues until the last particle is created. The smallest particle in creation is the zero point.
Genesis of creation: Now we reverse the story: in the beginning, the whole space is full of zero point with zero mass. But the nature of zero points is different. It will probably be 2 groups or 4 groups in total. They all ride on steady waves. Every moment they turn into a huge mass of zero particles. As these masses move, electric The currents rub against each other and create an electric arc. As a result of the electric arc: the first atoms are created simultaneously with the waves inside them. And these events continue until the largest electric arc occurs between the plates of the gas mass. Every great arc is the beginning of a universe.
As a result: every world revolves around itself. And they all revolve around the greatest electric arc (core of creation).
The main question: which came first? Waves or matter?
If we are a smaller universe in a larger universe, the answer is waves.
The world = different types of waves.
Sum of waves is a subset of the main wave. The main wave is the neutrino wave.
The neutrino wave is the link between the worlds.
As a result of the changes in the waves, different types of materials are formed.
Similar example: according to your definition: elements are made of protons, neutrons and electrons.. By increasing and decreasing them, different elements are created.
The neutrino wave did not make me like itself, but it took control of my physical mass.
My mass and the mass of any object changes at every moment and at every place in space because the neutrino wave changes at every moment and at every point in space. If there is no neutrino wave, I will be thrown into space. As the neutrino waves change, the mass also changes.
Hello. Why do we complicate the structure of the world? The world is built with a structure. And this structure is constantly repeated in all objects. The relationship between all objects is the neutrino wave.
Neutrino waves are moving in all parts of the universe: around stars and in interstellar space. Some places more and some places less.
It is clear that every charged and uncharged particle moves in every medium of space: energy is produced by the collision of neutrino waves of particles.
Light: The charged particle is neutral and has mass. Light is emitted only from the surface of the source. The particle of light is the smallest planet from its source star.
Gamma particle: has mass but is not charged.
In short: the light particle is emitted from the surface of the source and revolves around the source.
And gradually its circuit becomes more extended. The direction of rotation of the light particle is like that of the planets and it rotates around the vertical line of the source. The orbit of the light particles is stretched and stretched, and suddenly at a certain distance it is stretched (thrown) towards infinity. All details and formulas with full calculations will be provided soon.
The light that reaches us from distant stars must pass through space bodies and reach us.
The purpose of light is to return to the source and this is not impossible!
The work of stars of Bernour:
Very briefly: there are three modes.
1- Ineffective stars
2- A star that absorbs light particles that move near it. 1- It absorbs a large number of light particles. 2- Reduces the speed of light particles.
3- A star that repels light particles that move near it. The particle of light hits its environment: 1- It scatters in the form of rainbow waves. 2- Their speed increases.
Shorter waves hit smaller objects and are gradually absorbed by them. As a result, the farther the source is, the bigger and redder the waves reach us.
Note: Our sun absorbs light.
A variety of relationships between stars and between sets of stars with other sets in several articles soon.
I am building an energy harvesting circuit.
I want to know the ratio of the power consumed at a load to the incident power from the antenna to the circuit, so that I can evaluate the overall efficiency.
It seems that the transient simulation in ADS only provides the composite of the incident voltage/current wave and the reflected voltage/current wave.
How to measure the power of incident wave in simulations?
Please kindly give me some instructions if you know any answer about the question.
We assume that V(x,y,z,t) is the external potential applied to the quantum particle enclosed in a closed system.
What is quite surprising is that there exists another spontaneous component for V which comes from the energy density of the system itself expressed by,
V(x, y, z, t)=Cons U(x, y ,z ,t) . . . . (1)
Eq 1 is a revolutionary breakthrough.
Equation 1 means that quantum energy can be transformed into quantum particles and vice versa.
Additionally, Equation 1 (predicted by the B-matrix chains of the Cairo Statistical Numerical Method) eliminates any confusion about whether the Schrödinger PDE is a wave equation or a diffusion equation and provides a definitive answer:
she could be both.
Data I have : Significant wave height, Wave period, and beach face slope.
It is well known that two coherent optical light-waves are made interfere in LIGO and VIRGO Gravitational Wave (GW) systems (similarly to MMX experiment). The interferometers are configured in such a way that the interference is normally destructive, in order to detect differences from that state in presence of GW.
As a matter of fact, out of two waves generated, normally, nothing is detected after their interaction in the interferometer.
Is it the crystal of the interferometer to thermalize the energy of the EM-waves? Because otherwise if EM-waves disappeared thoroughly without a trace that would violate the conservation laws..
What we call the brain and talk about is just a storage tank. It acts like an electrical capacitor. In my calculations, the soul is a necessity, otherwise the elements of existence collide. Spirit is the coordinator.
Why did I use the word soul? Reasons 1- It happens only at the moment of collision. It happens in time equal to zero. 2- In that short moment, waves or forces take another form. The soul is the moment of change.
3- It is not organized. It is neither cause nor effect. It is in the zero zone. It is exactly between cause and effect. At the point of change from cause to effect.
4- As soon as the cause is stopped, it is stopped.
If physicists enter this field without fear of losing credibility, there will be no room left for superstitions and profiteers, and religious people will not dare to speak decisively about the soul.
I have no credit, everything I have is the result of your efforts. I just used your knowledge
General result: order of formation of organisms 1- Heart: inner core. 2- Soul: connection between heart and parts. 3- Brain capacitor: outer core and other components: star environment. Note: Inside the heart: there is a soul and an independent capacitor of the brain. I will prove it so far
All creatures are made of the same formula.creatures are made of different particles. Particles are made of atoms. And the formation of the nucleus of atoms is similar.
The best analogy for the brain is lightning.
Lightning is a type of electrical discharge that is caused by the transfer of static electricity between two clouds or between the cloud and the ground. And it is the electrical discharge that produces the intense light and sound.
In the brain: the impact of incoming and outgoing waves can be felt at any moment by creating heat and other currents. And after some time this effect disappears. And many of them are stored in something like a capacitor in the brain.
The set of components of the brain capacitor = the set of components of the outer core of the star.
Cranial brain: the layer is located on the outer nucleus.
Spirit: In the place inside the outer core where the internal waves and the outgoing waves interact, lines like lightning are created, which is called the spirit. These scattered lines appear and disappear at any moment and everywhere.
As a result, the average mass of the soul is zero.
Spirits (lightning lines) leave traces in the outer core environment. And the accumulation of those effects causes the brain capacitor to be built in the outer core.
Brain capacitor: It is the place to store the works of the soul.
Duties of the brain capacitor: 1- Collecting information: the effect of lightning lines is stored. If its capacity is full, older data or works will be compressed. The older it is, the higher the compression.
2- Production of awareness
3- Spiritual management

In each brain capacitor there is a black box that cannot be destroyed by stars or humans. This black box is held by the waves of the mother and grandmother stars.
After the destruction of the star, the main wave in the black box moves towards the parent star. This primordial wave is like a newborn fetus, but all his consciousness is preserved even after destruction.
The best analogy for the brain is lightning.
Lightning is a type of electrical discharge that is caused by the transfer of static electricity between two clouds or between the cloud and the ground. And it is the electrical discharge that produces the intense light and sound.
As a result: the brain has no mass. The brain has effects that occur somewhere in the stars or humans. Inside that place: the impact of incoming and outgoing waves can be felt at any moment by creating heat and other currents. And after some time this effect disappears. And many of them are stored in something like a capacitor in the brain.
The brain capacitor evolves and gradually controls the brain lightning.
A simpler definition: consciousness is random. When combined with experience, science is born.
The greater the capacity of the brain, the greater the thought.
I didn't think about this before. I am sending these answers at the same time as thinking.
I have a strong support for the answer.
My Support: This is my new and different atomic model.
which is stored in the capacitor of my brain.
Dear Friends,
Can you see the waveforms?
- If we use PWM generation with a sine wave and a triangular wave ranging from 0 to 1
- If we use PWM generation with a sine wave and a triangular wave ranging from -1 to 1
Are both the same or different?
What is full wave simulation in antenna ? How to simulate in CST Studio software? Can anybody explain.
The diffraction of light has been referred to as its wave quality since it seemed there was no other solution to describe that phenomenon as its particle quality and subsequently, it exhibited wave-particle duality.
As per ASTM D4428M-14 and IS 13372 (Part 2): 1992 (RA2001), the Modulus of shear, bulk, and elasticity can be calculated directly from Vp and Vs. How can I calculate specific moduli such as the tangent shear modulus, rotational shear modulus, modulus reduction, constrained modulus, and secant modulus based on the cross-hole seismic test (based on the velocity of P and S waves & Poisson's ratio)?
Please share your thoughts and literature on the above-stated-problem.
Currently going through impact hammer test of cantilever beam(200mmx20mmx2mm) which is made of particulate composite(Epoxy/PZT/CB). Hammer sensitivity is 2.25mV/N and accelerometer sensitivity is 100mV/g. I'm trying my best to hit the same spot without skewing to get the average value in order to find driving point. Here are some problems I've been facing.
1. Shrinking magnitude at FRF
Let's say I attached the sensor at point A and hit the opposite side. I got pretty neat 2 sharp peaks with antiresonance placed between them. When I hit the same spot again, the 2nd mode peak of FRF dropped down to 0 which become barely visible peak. Same thing happend when I hit several more time. Can I say it's because of nonlinear result due to micro cracks and voids inside the beam? (I checked many voids by SEM image)
2. Phase
If I check the degree change from 60 to -120, then is it ok to assume resonance there? And does 360 degree changing and density of phase graph doesn't have any meaning at all? Lastly, does the 180 degree phase decrement going through long range of frequency mean high damping?
3. Coherence
I know the best result of coherence is mostly at 1 with slight drops at antiresonance points. In my case, the coherence is showing a noisy wave shape or like a thick dense phase graph. I've been trying to hit the same spot as uniformly I can. What is the cause of this result?
Thank you.
Hi everybody. I irradiate a biological object with a plane wave, when displaying a graph of the power loss density, distortions appear in the slice (blue areas), but there are no such distortions at the edges of the biological object. When I output SAR using this loss monitor, there is no such distortion. How can this be explained and corrected? Thank you very much for your time.
Hello everyone. I need a wave cahnnel for offshore wind turbine design. Can hydraulics experts help me in designing the wave channel with quotations links?
I am doing a literature review on acoustic properties of layered media and I am struggling to find articles, resources etc to add to the review. Does anyone know of any seminal papers in this field that I should be reviewing?
We assume that the answer to the question of whether the quantum wave function Ψ is a scalar, a vector or not is that it is none of these.
Ψ is an abstract mathematical operator that has no physical meaning in itself.
The currently accepted procedure for describing Ψ in a given isolated quantum system is to construct the time-dependent Schrödinger SE equation for that particular system and then solve it by the method of separation of variables.
The importance of Ψ is that it conveys the phase of the system in x-t space and therefore can explain its wave properties such as interference, diffraction, degeneracy, etc.
We propose a simple alternative to solve for Ψ^2 (and not Ψ itself) which has a physical meaning of quantum particle energy per unit volume (or probability of finding the particle in unit volume of space unified x-t), then in a final solution last step to find Ψ as the square root of Ψ^2.
It is clear that the proposed technique completely neglects SE as if it never existed and proceeds to solve the Ψ^2 quantum system via a well-established probability diffusion equation.
I know I'm crossing a minefield in investigating this question.
There are at least two incompatible theories:
classical EM theory, where wave energy is continuous and
QM quantum theory, where the energy of EM waves is essentially discrete or quantized in photons.
So it depends on the theory we use to analyze this problem, not on the frequency of the wave.
If we follow QM theory, the answer is definitely no because the photon must have a positive momentum and therefore a positive frequency.
On the other hand, if we follow the classical theory of electromagnetic fields, the answer is yes but the photon itself is not defined.
The instrument provided data of the IR spectrum is in %T vs wave number. But the peak is in the 3600 to 2600 cm-1 shows more than 100% transmittance. What are the probable reasons behind it? How can I solve it? The IR was done in ATR. Thank you.
We have elastic scattering excitation function data in tabular form and want to obtain partial wave scattering phase shift data for each partial wave say l=0, 1, 2....whats the process to do so and is their any code available to do so
I tested DNA structure (5uM dissolved in 50 mM Tris) using JASCO-1500 but found no peak at wavelength 220-350. The results look like a wave shape throughout the wavelength...
I am writing a project on electronic structure with a molecular approach and a surface approach (plane waves). I have knowledge of the molecular part, but I am having difficulties describing the project for plane waves. I intend to use Gaussian for molecular structure and Quantum Espresso for plane waves.
I have the methodology for the molecular part and would like to know how to describe the same items for plane waves. Could someone please help me?
Below, I am placing the methodology for the molecular part:
Construction of systems and structural studies Reactivity index calculations (for the molecular part, Condensed Fukui Indices to Atoms are used) Reactivity index calculations (plane waves ???)
Opto-electronic properties (for the molecular area TD-DFT)
In particular, the aim is to evaluate data associated with the energy and spatial distribution of frontier orbitals, local and global density of states, reactivity indices, optical properties of the materials composing the chemical species, in order to establish simple rules for the preparation of materials with optimized properties.
Adsorption study
It is intended to evaluate adsorption processes of chemical species and reactions with the systems of interest through two different approaches: i) calculations of molecular electronic structure and ii) calculations of surface electronic structure.
Calculations of electronic structure Optimization of geometry of adsorbed systems will be performed in a DFT (and/or Hartree-Fock) approach with Grimme corrections to better describe interactions between unbound systems.
And how does the calculation of electronic structure for the surface work?
