  1. INow, Your out of context quotes seem not to address my actual points or examples. I could suggest reading my post again, bearing in mind that I'm trying to describe how actual sports fans approach issues of fair competition, but I can't tell if you're really open to that. As regards "I reject your premise that allowing transgendered females to compete in sports as female is unfair. " this was not my premise. Indeed, prior posts of mine pointed out that some sports are finesse-based to where body mass, fast-twitch muscle and aerobic capacity don't much matter. Some sports

  3. There is a lunatic fringe to both Left and Right, though. The pictures of leftie antivaxxers in the OP obviously belong to such a fringe. What I meant was that we can all chalk up left and right nutcases till the cows come home, but on its own that means little. I suppose the point we are all making in the thread, in our different ways, is that something different and sinister is going on today, viz. that loony ideas seem to have migrated from the lunatic fringe to become mainstream in today's US Republican party. It's Hofstadter's "Paranoid Style", but on steroids. Rupert Murdoch is larg

  4. Sorry, but I see this as wishful thinking. In reality, sports in general seems to be just another way to pit rivals against each other in a non-lethal way, but only exacerbates the problems with modern humans competing for "fun". We've worked hard so most people don't have to compete for resources, yet the animal in "us" wants the pleasure of crushing "them". The mindset sports encourages in modern, money-oriented settings is similar to modern business practices, and "winning at all costs" takes precedence over "reaching the top together". I don't think sports unite us, just the opposite

  6. I’m okay with that. Tho please note that I reject the underlying premise that my advocacy for accepting trans women as women and trans men as men “demeans the very idea of diversity.” Lol Your use of the word “if” here is the sticking point for me. I agree with your basic logic, but I’m not seeing that approach in obvious display here. Instead, we seem to have lots of preconceived conclusions about trans women having advantages in sport which then go in search of data supporting those conclusions (or don’t seek that data at all, in fact). That’s different than having uncertainty

  10. Einstein's equations in general are complicated. They involve second derivatives of the metric arranged in an object with many (10) components (Einstein tensor; LHS of EE). And they are non-linear. On the RHS of Einstein's eqs. you have the distribution of matter, radiation, etc., in the universe. Schematically, they are: Geometry = matter Under assumptions of symmetry at large scale (isotropy=space is the same in every direction; homogeneity=space is the same everywhere) you get to a simple form of EE that's FLRW (Friedmann, etc.) that only involves the scale factor, which codifies

  11. "Any honest observer" is an argument fallacy similar to No True Scotsman. If I disagree that a focus on fairness is disingenuous, or a cudgel, then my disagreement has no merit because you've already ruled me as dishonest. Surely you can see this is not the way to move me or anyone towards your position. (FTR, I accept all LGBT people for who they are, to the point of speaking out publicly and joining street demonstrations, at various points in my life. ) Fairness is central to sports, as anyone who has ever attended or watched a sporting event knows.

What Charon shared, however, was based on the largest ever study done on trends in ultra marathons over 23 years across over 15,000 events and it included over 5 MILLION results. But yeah… I agree. If you look at just ONE runner in the top record holding spot, then the claim doesn’t “SEEM” true.

To model the behavior of the universe in ways that minimize human bias; to move forward with the recognition that all models are only at best provisional, and with a willingness to reject them when evidence demonstrates that they're flawed and unrepresentative in some way. Science is about building maps, and our task is to recall that all maps can always be made better and also that the map is not the territory.

  15. I think the point made about basketball (it tends to discriminate towards very tall people) is a fair one, as it underscores that all sports at the higher levels are going to be somewhat exclusionary and attract people with a certain anatomical blueprint. No one has proposed "professional short people's basketball," or "football (American usage) for the small-boned." In this sense, all sports (except those based purely on grace and finesse, like diving) tend to filter out those whose body type does not adapt well to its contact situations or need for inertial mass. The problem seems to be m

  17. Except perhaps for cold fusion and homosexuality, these are not Science-- they are applications of science coupled with engineering, management, and in some cases marketing decisions. It is the applications of science (among other things), sometimes poorly conceived, that lead to disasters. Science not applied generally does not hurt anybody. As for homosexuality, It is merely one facet of the normal range of human behaviors. Not my thing but I don't think it needs a cure.

  18. These are good points. Especially with regard to sports I find it laughable that folks are so hung up on some objective measure, whereas literally everything in a sport is based on the creative design of a game. Fundamentally, I have not heard any argument that addresses why performance differences cannot be used to create competition categories, whereas almost everything in sports is (e.g. different leagues, or competition levels). Taking F1, for example, from what I understand it is actually open but few women qualified. This is perhaps not terribly surprising as only few women compete

  19. His comment is uninformed. There is nothing in the spike protein mRNA that makes it vastly more stable, and the instability of mRNA is well known. It is fairly common to use surrogates for these type of studies. Even if it was much more stable, we would be looking at a couple more days at best, which, unless you are talking about mayflies rarely falls under the moniker of long-term effects. I just quickly calculated the total detectable lipid concentration, which dropped by that amount. So yes, it is cumulative for all organs. Again, it is based on how we generally metabolize li

  27. The size of the atom is of the order of 10-10 metres. The Planck length is of the order of 10-35 metres. So the distance from the centre of the atom to the edge is of the order of 1025 metres. As a comparison the distance from Earth the the observable horizon is of the order of 1026 metres, or not much further comparatively speaking. Now the surfaces of the electrodes is rough at the order of 10-7 metres, so there will be mutual interpenetratration of the 'touching' surfaces long before the atomic scale is reached, let alone the Plank scale.

We might also have gotten to chemistry and biology sooner, with no derailment of "perfect spheres" and "ideal forms" and "gods' images". In any case, we would do science of some kind, always, because it's useful to our to survival and satisfying to our curiosity.

There are a lot of chemicals in smoke- most of the research focussed on tobacco, but apart from nicotine, most of the chemicals will be similar whatever you burn. And so I can tell you that much of what I can smell are compounds like phenol and guaiacol together with acrolein, naphthalene and others. It's also possible to connect a gas chromatograph to a glass funnel and put your nose in that funnel. That way you can smell the compounds as they are separated out. (so you knew w

TheVat made a worthwhile distinction between concrete and abstract nouns This is one of the advantages English has over Mathematics. So to discuss your question, let us consider two well defined sets. 1) The set of people born on or after 1950. 2) The set of people born on or after 2050. The first set has a specific finite number of members. This number is given (measured) by the natural or counting numbers, otherwise

  32. Yes, basically. At very low doses most mercury can be excreted with a half life of a few days to two weeks. However, especially at higher dosages the excretion pattern becomes more biphasic with a the fast phase (i.e. <2 weeks half life) only eliminating part of the ingested mercury. The rest follows a much slower (1-2 months half life) elimination pattern. If your intake outpaces the elimination time, you start accumulating which can result in issues.

Interstellar travel capability is no more a basis for assuming that entities are peaceful than transoceanic travel capability was - as the Taíno and Mi'kmaq and other indigenous peoples learned to their chagrin. But since the technological discrepancy here is greater, and the alien species doesn't share our predatory past, I was assuming that, if they were not benevolent, they wouldn't bother to make contact: they'd just take what they wanted and ignore

  36. The roots of science as we know it, I think, are already present in Roger Bacon and Galileo. It's this emphasis on observation and careful measurement that really did it. I see some kind of fruitful meandering from the empirical side (Francis Bacon) to the mathematical/rational part (Descartes). Advances have come in successive emphasis on one and the other. Aristotle (empirical emphasis) got his physics badly wrong. Much later, Descartes (pure reason, mathematics) got his biology of sorts badly wrong. I think this tension echoes through the centuries even today (cosmology; multiverse, pr

  39. The maximum current between any two points in any circuit flows along the path of least resistance. When an unintentional low resistance path occurs between two conductors (perhaps one being earth) a very large unintentional current can flow. This develops a large amount of heat as the heating effect is proprotional to the square of current. So (metal) conductors can get very hot and if theya re touching something flammable they can start a fire. Does this help, ask for more if you did not follow any part of it ?

I'll try a logical explanation with more detail without referring to math of specific laws of physics this time: Let's say two hypothetical devices are working perpetually* as a unit without external energy source. Perpetual motion device A feeds energy (1) into device B and then device B feeds energy (2) to device A. Since no external energy is added and operation is perpetual there is no internal energy wasted; efficiency is 100%. Device A runs from the energy provided by B and B runs from the energy provided by A. Hence, over time, A must supply B with the same amount of energy that
