  1. I watch MMA. Some women in the sport have raised concerns about transgender athletes, which is how it came to my attention. Some in the medical have put forward scientific reasons to legitimise this concern, others refute these reasons, and that debate continues within the medical community (links have been provided in the course of this thread). To have these concerns just brushed away as ridiculous, and to equate them with resistance against gay marriage is unhelpful at best. It's the sort of rhetoric that pushes people toward Trump and Brexit, as it exacerbates the us vs them attitude that

  2. I'm 61 years old and was born in Liverpool, England. As a child (perhaps 8 or 9) my mother saw an ad in a magazine to buy a set of children's encyclopedias, with this deal we got all the books at once and simply paid the small monthly fee until paid off, we were poor so this was not trivial. I was actually unwell the day these books arrived, I was lying under a blanket on a couch near our coal fire when she walked in and announced this purchase and carried in these two large heavy boxes, dumped them by the couch and left me to read, this was a life changing event for me and led to my

  3. 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

  4. 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

  5. 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

  7. 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

In fact, I will demote my example, pending more verification, to "rumor from a small prairie town. " Digging further, it looks like the governor (a conservative Republican) was alarmed by a case in Connecticut: between 2017 and 2019, transgender sprinters Terry Miller and Andraya Yearwood combined to win 15 championship races, which prompted a lawsuit. It looks to me (and my apologies for not sifting through all this earlier) like the administration here did not actually find a well-do

  11. 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

  12. 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

  13. "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.

  14. Except, it is. What you shared are world records… examples of ONE runner being best… basically, anecdotes. 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.

  16. 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.

  17. 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

  19. 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.

  20. 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

  21. It’s really not. You continue misusing that term. It is not an ad hom no matter how many times you repeat yourself claiming otherwise. How about this… Consider my mention of “comprehension challenges” as an observation based on the evidence available; a sincere attempt to better understand why this discussion with you feels so consistently full of friction. Please try not to consider it as an attack on you because it simply is not, nor is it an attempt to bolster my own position with fallacious logic. It’s simply the only way we can reasonably explain why so very many interactions

  22. Hello. The slits should be at the top and the bottom of the pipe serves as a bowl. On another side the drain must be sloping. About 1 cm per meter. The accumulation of the water downstream means that by its level will cause water to pass through the slits. The gravel below the pipe is probably because if it touch the ground, it will plug and accumulate this mud in the drain. Be careful during your installation because it is said that for specific condition in agricultural spreading, the slits of the drain must be downwards!

  23. This is certainly NOT like gay marriage. Gay marriage doesn't infringe on any one else's rights. As JC has repeatedly pointed out, Trans athletes infringe on women's rights to fair competition. And there have been realistic examples given, Swansont; I posted one myself. INow and Zapatos are willing to put the rights of those 6 people ( the number of trans athletes, he claims ) above the rights of more than 50% of Earth's population. So, are we again telling women they are not even second best to men, but actually also behind trans people ? And Dimreepr seems to think that the onl

  24. Again. Elite female athletes cannot always compete equitably with 16 and 17 year old boys. The fastest female 100m runners in the World can be beat by some 16 year old boys. Unfair to cisgender women. No amount of testosterone will allow the fastest women athletes to compete with the fastest men. It's not just about testosterone. (or simply willingness to identify) This will be a failed experiment, hurting both cisgender females, and transgendered athletes who will likely be treated unfairly. Hopefully they will be treated as respectfully as possible...and the animus

The gold itself (the atoms of a given isotope) are identical I'm not even sure you could rule out life emerging more than once on earth. Abiogenesis happens, and then some cataclysm wipes it out before it can spread and take hold, and a thousand years later abiogenesis happens again. This could potentially have happened many times. None of the evidence would have survived.

Insects can pose specific problems, and I'd have no qualms fumigating or getting rid of true pests, but if there's no need to kill those bugs, I don't do it. I especially wouldn't kill something to impress a person. That seems like animal behavior, something I try to rise above. I remember doing dumb things to impress women, but eventually I learned to appreciate the ones who liked learning about bugs rather than the ones who wanted me to kill them.

The cornea is usually transparent, but it can have scarring or uneven curvature, making for a fuzzy view. The aqueous humor is a liquid that fills the front part of the eye, most always clear, but hi-pressure of this fluid ( due to poor drainage ) is the cause of glaucoma and loss of optic nerve function. The lens is next, and both the lens and its capsule can become cloudy. The capsule can be cleared with a YAG laser ( see Yag laser capsulotomy ), but once the lens becomes obscured, a condition k

  31. Doesn't matter what happened in 1920, and what the intention of segregation was back then. The point is, it works now for the right reasons, simply because in many disciplines men have a clear advantage over women. If you want to ignore this fact then that's your choice. Segregation and classification in the modern era serves a useful purpose, where it allows for more people to compete and be recognised for their performances. That is where the most useful equal opportunity arises. It allows for women to be recognised and respected as equals to their male counter parts and this then should ext

  32. If one analyses UFO reports and close-contact stories, and from the purely story-telling POV, it all sounds very much as humans (bipedal, anthropomorphic) from the future doing the time-warp/FTL thing (or from a parallel dimension) and trying not to leave too much of a fingerprint (so as to avoid big ripples of retrocausal interference). These 'beings' are invariably portrayed in such a way that the number one feature that strikes me is how much they look like moderately-distant relatives that care about us. I wonder if the whole thing is not just a re-edition of the biblical stories

  34. I don't see anyone attacking transgender people, so not sure where you get that impression. I see folk arguing the "possibility" that transgender women athletes may hold a natural advantage over cis-gender women athletes. I think this is a fair argument to have, at least until it is proven one way or another whether it holds true. MigL pointed this out quite clearly when he stated the development of young males during puberty and how their bodies develop specifically for increased strength and endurance. Which stems back 100's of thousands of years in evolution, likely due to the males g

Cardiopulmonary cessation hasn't been used in most places since around the 1980s Not by most definitions of death. It needs to be irreversible.

  39. The properties of the Higgs field were known more than 50 years ago, when P Higgs first postulated the Higgs mechanism to explain the masses of the W+/_ and Z bosons, which result from the symmetry breaking of the Electro-Weak force. The hi energies at which its bosonic field excitations ( Higgs boson ) become evident was always out of our reach, until the LHC was built. The Higgs scalar field is well known: we just needed to find its bosonic carrier particle, to verify it actually exists. So, what exactly do you mean by 'how the insides change' for a scalar field ?

  43. I must profoundly disagree with you here. There are no axioms in Physics, theoretical or otherwise. In Physics you will find Principles, eg 'The Principle of Relativity' Principles are the nearest Physics gets to axioms. But then Physics is quite different from Mathematics (and Logic) which have axioms. Axioms cannot be derived or proved. The best one can do is to establish self consistency with other axioms and derived lemmas and theorems. That is how they work in Maths and Philosophy. In Physics the equivalent of derived theorems are derived law

It has internal weapon bays ( otherwise it would not be very stealthy, would it ) for carrying missiles or JDAMs ( GPS guided bombs ) and the thrust available from its engine is enough for VTO in this configuration.

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
