Why is the laser spot diameter smaller with a larger beam?

The following formalism gives the simplest estimation:Teta (diffraction Limit)=1.22 lambda/Dr= Teta * fA=Pi* r 2Where lambda, D , r, f and A denote to be laser wavelength, laser diameter, radius...

Why the disturbance diffuses to larger distance if we have fluid at rest with low viscosity compared to fluid with high viscosity?

The throwing of a stone in a lake (can be approximated as hydrostatic case) creates ripples in the water. The ripples or the disturbance associated with this is elliptical and travels uniformly in...

How to explain the observed physical phenomena of zero PL intensity between two strong emission peak?

In the last month, I carried out PL spectra measurement on a luminescence materials at various temperatures. From the obtained result, I found an very interesting spectral region where zero PL...

Does the repulsive interaction between Fe and Al in the atomic simulation agree with the facts?

I have constructed a atomic asperity junction between Al and Fe. However, a repulsive force occurs before the snap to contact happen. This is quite different with the phenomena from some relevant...

They can make friends theory of general relativity and the ether?

Attempts to describe general relativity by a continuum in Minkowski space were made but were unsuccessful. Please see how it turned out in my article "Applications of the Local Algebras of Vector...

How determinism is compatible with free will?

Determinism concerns the relationship between cause and effect, between natural law and universal single specific phenomenon. In nature, given a cause or a law, it can occur only a certain effect...

Are you aware of any serious enquiries about a possible structure in God's current way of intervention in the world?

John Polkighorne's work seems to define an appropriate context, simultaneously scientific and religious, to consider a possible continuous interaction of God with the world. Between a God that...

Are empirical methods and correlations useful in the context of the current scientific developments and in the Engineering practice or other areas?

The extensive use of empirical correlations and empirical methods instead of scientific approaches can be controversial. Theoretical laws in many physical phenomena are frequently difficult to...

Any physical phenomena where the discharging/decaying curve is hyperbolic?

Have you ever tried to connect a charged cap to a digital (say, CMOS-inverter-based) oscillator as its load, and let it be discharged? If not, you might be surprised that the voltage on the cap...

What is the difference between "free entangled state" and "distillable states"?

Negativity(N) is a measure for free entangled states. Everywhere N>0 the state is free entangled and for N=0 the state can be bound entangled state or separate (we can not realize here by...

Why can entanglement increase (revivals) under purely local operations?

We explain this apparent paradox in the physical ensemble description of the system state by introducing the concept of ‘‘hidden’’ entanglement, which indicates the amount of entanglement that...
