What about statistical biology (analogous to statistical physics) ? is chinese medicine the solution?

Biology is presently focused on microscopical phenomena. There is a need of simplification. Whole body biology is a matter of cycles and equilibrium between the cycles. Chinese medicine may be...

Does ageing of materials due to high energy particles and electromagnetic waves lead to errors in elementary particle detectors?

Ageing of materials in particle detectors due to high energy particles and waves affect all the set up of the detectors, from trajectory detection to luminosity detection. Indeed, this ageing...

Are particle physics experiment (especially at the CERN) dangerous?

I mean that they are accelerating protons, neutrons and lead ions at very high speeds and that is very similar to an atomic bomb explosion. Are there cases of cancers in technicians, engineers and...

And if it was possible to desalt seawater with solar energy in a cheap and easy way?

By setting up a sun-reflecting parabola (with for example recycled metal-old cans) and oriented towards the sea water and thus evaporating sea water. The water vapor would be desalted and may be...

Is the Planck's constant really a constant?

Or does it follow the expansion of space (i.e. of the universe)? How to measure it if Planck's length is the space unit?

Can we get rid of time in particle physics?

When using propagators and potentials (like the Yukawa one), time is not explicit. Should we use different forms of the propagators and the potentials in a 4d spacetime with time being a 'regular'...

In molecular dynamics simulations, do you know potentials appropriate for surfaces/interfaces?

I mean that most of the potentials (Lennard-Jones, DLVO etc..) have a spherical symmetry thus are not appropriate when getting close to a surface/interface. Indeed, the physics of a surface is not...

Does it make sense to use thermodynamics and statistical physics in nanophysics?

The physical properties (for example, of a material) at the nanoscale are not the same as they are at the macroscopic scale. Thus, can we use thermodynamics and statistical physics to explain...

Did you notice that the first family of fermions and the Higgs particle have masses which are powers of 2?

Their masses are powers of 2 in the Planck length basis. Do you have an explanation for that? Calculations must be done in the (x,y,z,t) space.

Would it be possible to make a theory of elementary particle physics in real space?

I wrote a paper about the Higgs field in real space. I do not know whether it corresponds to the well known Higgs-Brout-Englert field. Any idea?

Is time equivalent to a space dimension?

I made a dimensional analysis of Einstein field equation, and I found L=T (space dimension= time dimension). Do you have an explanation for that?

Can out of equilibrium thermodynamics learn from first order transitions?

Out of equilibrium thermodynamics study often changes in a structure with a long time scale. Could first order transitions give informations to out of equilibrium evolving structures? I mean: the...

Is there a relation between the energies of covalent bonds in SiO2 glass and the fact that glass transition is not a phase transition?

I mean: is glass transition a superimposition of phase transitions due to different energies of the SiO2 covalent bonds? In other words, is glass a poly-nano-crystal?

Why is the pressure P in the Friedmann cosmological model negative to account for the accelerated expansion of the universe?

in the Friedmann model, the pressure p is negative. But the dimensions of p are force/r^2 (1) where r^2 is a twodimensional surface. If our universe is threedimensional, the pressure would write...

In the Friedmann model, it is possible to link the radius of curvature of the universe with time; is this possible with more sophisticated models?

a consequence would be that time is 'only' a function of space dimensions...I made the demonstration in the frame of the FLRW model and a vacuum dominated universe. To question the nature of time...
