- that's not right. if photons were truly spin 1, there would be 3 spin eigenstates available, but in fact there are only 2 (Sz=0 is unavailable). the pithy argument invokes the absence of a stationary frame of reference. for all practical purposes, photons are behave like spin 1/2 particles (despite being bosons). see, for example, the jones algebra / calculus.
- i understand what you mean now. you are referring to the yield of treasury bonds, which, at least historically for <10 year tbills, do track the fed rate.
- What do you think you mean by saying 'drives interest rates down'. It seems a leap to think the fed, the entity that establishes the interest rate, will react in the way you describe.
- i did not read the study. an obvious confounding factor is that doctors with better board scores are hired into better hospitals with better patient populations, and thus better outcomes.
- to be clear, this is an opinion pertaining to the preferred behavior of eg the american government and not anything like a summary of its history in this regard. that is, the tech industry since its inception in the 60s has accepted, to its benefit, [massive] federal subsidy.
- probably not - 'monads' are an interface (typeclass in haskell) for which specific functions (bind, unit) need to be defined. you can do monadic programming in any language, including python. that is, functions are central to the implementation and use of monads, so being 'function-free' seems contrary.
- with error correction, qc is entirely distinct from analog computing. that is what makes it even remotely viable, theoretically.
- yes, this a very reasonable though inexact interpretation.
- viscosity has very interesting units - stress (force / area) divided by rate (1 / time). viscosity is measured (a field known as rheology) by, in some way, moving a thing through a fluid at increasingly fast accelerations, or equivalently, at increasingly high frequencies. that is, imagine moving your hand back and forth in a fluid - the faster you do so (the number of back and forth motions per second), the more resistance you will feel from the fluid. for newtonian fluids, the resistance you feel (measured in force / area, ie the area of your hand), is proportional to the frequency of your hand moving back and forth in the liquid, so, the graph is a line. non newtonion fluids do not have a linear relationship between shear stress and shear rate. air is also a fluid - all gasses are, and thus possess rheological properties. air, however, at stp, is essentially an ideal gas, that is, it is non-interactive, and thus, has 0 viscosity. the point here, is that viscosity is a consequence of the interactions of particles. as gases become denser, their viscosity increases. liquids, for comparison, is ~1000x as dense as air. the details of how molecular interactions lead to viscosity is actually quite complicated.
- the statistics of a collection of particles, ie fermions or bosons, depends on their symmetry under commutation. that is, the wavefunction of the collection of particles, which does have physical meaning isofar as its square is the real density of the particles, must also obey this symmetry, ie it must negate (-1*) under exchange of two identical fermions. so it's not that the 'fermion' cares, but that the consequence of (anti)symmetry under exchange affects the density of a collection of such particles, which leads to a measurable difference in their statistics (how likely they are to be close to each other) compared to non-symmetric (normal) counterparts.
it is not ad-hominem to try to understand a person's motivations for expressing a particular opinion, which is why the above poster referred to 'character' which is not specific to the definition of ad-hominem, but is in the spirit thereof, that is, distracting from the argument. but if the person has shown themselves to be working contradictorily to public health policy, especially in consideration of the hippocratic oath, you may ask reasonably what they are about.
