  1. So it seems you are advocating to drop scientific rigor whenever you feel like it. I am pretty sure that if you have bag with 1000 skittles and just one is deadly, you would just assume that the whole bag is safe, too. I mean, it is just nitpicking.

  2. I think you need to put the risk in context to make a good judgement on it. For example, when I was still teaching I had roughly 200 students I saw regularly in the course of a day. 2% would be 4 students that I knew well. If we were talking 2% risk of a deadly consequence - absolutely unacceptable. But, a useful medicine with a 2% risk of children missing a few days of classes -- totally OK.

  4. We're seeing a lot of fascist tactics around the world, which tend to diminish the works of science and freethinkers, while glorifying both the military and corporate establishments, and simultaneously degrading labor, unions, marginalized peoples (LGBTQA, PoC, etc), civil rights, free media, fair elections, and constitutional protections. I don't know about other countries, but the US has a tax structure that lets individuals sit on billions of dollars in personal wealth, and most people don't understand how much money that is, and how dangerous it is to allow individuals to keep that much without re-investment. For instance, let's pretend you get paid one US dollar every second. That's $60/minute, or $3600/hour, 24 hours/day, 365 days/year. Pretty outrageous pay, right? At that rate, it would take you between 11 and 12 days to make a million dollars. But at the same rate of pay, to earn a billion dollars would take almost 32 years. It's ludicrous that anybody needs that much money, and furthermore it's obvious that the folks who make multiple billions of dollars in just a few years are doing so off the work of others while those others are barely making ends meet. I don't think this is human nature at all. I think most people aren't extremists, but we've allowed the extremists in leadership positions where they've lobbied to make their money do things it shouldn't be able to do. This is NOT normal. But it also doesn't have to lead to disaster. I'd like to see an end to rampant capitalism. We need a much better mix of social, state, and private spending, imo, where capitalism keeps it's greedy fingers out of socially-funded programs.

  5. Since there is some interest in this subject I will post the outline mathematics. I am sorry I can no longer do the LaTex since SF will not let me post from WinXP. So if anyone can help with that I can expand. Basically we start with Laplace's equation in 3 dimensions, in polar format, and apply a potential , V. This can be colour value /intensity, or other quantity to produce the 'ripple' across the object. Successive radial (r) values of V are calculated for various values of two sectional angles theta and phi., where it intersect the object from geometrical model This is my first equation. The general subject is called spherical harmonics, which is concerned with solutions to this equation. A homogeneous algebraic equation separating r and the angles in the form of my second expression, rnf(theta, phi) gives values of V satisfying the first equation, in polar coordinates. These are known as solid spherical harmonics of the nth degree. The function f(theta phi) is known as a surface spherical harmonic of the nth degree. The equation can be simplified by symmetry when V is independent of phi. This lead to my second equation whcih upon the transformation indicated becomes Legendre's equation The solutions are known as Surface Zonal Harmonics, as indicated by John Cuthber. These may result in 'patterning'. This is not only used in CGI but also in computer tomography (CT scanning) via a finite element mesh. The equations are normally solved numerically by substituting suitable simple function such as' hat' functions on the mesh, with the computer doing lots of calculations.

  6. It looks to me as if Rayleigh waves, as observed in earthquakes, seem to be of this type: https://en.wikipedia.org/wiki/Rayleigh_wave

  7. When you write down a function it needs to be valid for any value of the variables. Not just at one, particularly when it diverges. Units matter. ! Moderator Note Since you’re just repeating this nonsense, there’s no point in the thread remaining open. Do not bring this up again

  8. Binary, in this context, is not the same as binary in mathematics. It merely describes the status-quo, where the vast majority of humans are one sex or the other. To concentrate on such a tiny number of exceptions proves that you've got no substantive argument, and are reduced to nitpicking again. Gender on the other hand is wide open, as I've stated plenty of times.

  9. Not every game is won by strength alone, besides you can't know that before they play the game; and no, your suspicions doesn't count as fact, even if it seems so obvious; that's not the scientific MO 'Intoscience'. It's quite telling that the defence has yet to answer the very simple question, why do you object to them playing with someone who doesn't object to being played with? More commonly know as consent in the world of sex... 😉 WTF has this got to do with transgander athlete's? I bet your an old fashioned man's man, because you too are drowning in the plughole of excuses... You don't have to accept that the spectrum exists, you may not understand I accept that, but you must see that it's red, green and blue that colour's the world??? Sorry, if you're blind that's in bad taste... 🧐

  10. Hello , The present theory explores the behavior of the expression of relative mass M(v) with respect to the speed of light (v=c)\ and suggests that dark matter or dark energy could be composed of ordinary particles with mass that have reached the speed of light. The theory delves into a mathematical analysis of the series representing the relative mass function, M(v), and discusses its divergence at v=c, drawing parallels with the regularization of the Casimir effect using the Riemann zeta function, which gives M(c)=-M(0) at v=c. It proposes the existence of a natural phenomenon that accelerates ordinary matter with mass to the speed of light and transforms it into dark matter or dark energy with negative relative mass and finite energy. 1.Representation of the Divergence of Relative Mass at v=c: Consider the function of Relative 2.Application of zeta function regularization on the divergence of relative mass at : You can just separate off the divergent part of and define it via zeta function regularization. Define: 4.Representation of the Divergence of Relative energy at v=c: Due to the definition of the energy-momentum four-vector, in particular its time coordinate, we end up with the expression of the total energy of the particle in the laboratory reference frame, that with respect to which the particle is animated with the speed v because the energy depends on the frame of reference in which it is calculated!) in the form of: If we interpret its results, there may exist particles with a mass m0 and a negative relative mass -m0, having a negative total energy and a positive rest energy, along with zero kinetic energy. These particles could be generated by a physical phenomenon that accelerates particles with mass to the speed of light and could be linked to dark energy or dark matter. 3.Analogy of the theory with Casmir effect: Here is an example of using regularization via the zeta function in the Casimir effect: Mathematical calculations lead to the famous divergent series 1+2+3+4\ldots However, the physical results do not correspond to infinite values for the energy of the moving plates. To resolve this issue, we applied regularization through the Riemann zeta function. Eventually, we obtain a finite value of -1/12 for the divergent series1+2+3+4\ldots and this result provides a good explanation for the Casimir effect. In analogy with the Casimir effect, it is possible that the value -M(0) obtained from the divergent series representing the relative mass at v=c, U0+U1+U2+U3..., has a physical meaning to explain 95% of the missing energy in the universe. Hence, my hypothesis suggests the existence of a natural phenomenon that accelerates ordinary matter with mass to the speed of light and transforms it into dark matter or dark energy with negative relative mass and finite energy. Could you please point out any possible errors in this new theory? The issue with the unit of measurement has been resolved.😀

  11. Yes, but they have a total negative energy -m0c^2. That can explain dark matter or dark energy, as we can see its negative energy effect after this transformation by this phenomenon...
