Sorry for the confusion, CharonY. As we were discussing testosterone based performance enhancing drugs, I didn't think I needed to mention testosterone based hormone therapy which would ' enhance' a 'natural born' female's masculinity for gender reassignment. I apologize for my unfamiliarity with pronouns that multiply daily. Please explain trans-man and trans-woman, with respect to naturally born and surgically/hormonally reassigned, so that we may discuss the same thing.

Actual magnetic monopoles are excluded by one of Maxwell's equations. Nevertheless they can be included, and have been theorized to have been created at certain stages of the universe's early evolution, specifically at domain boundaries. One of the explanations for their rarity is the 'dilution' brought about by inflation and subsequent expansion. They are mostly predicted by GUTs, along the same lines as Supersymmetric particles, which have not been observed either. If you understand a little Physics and math, this might be a good place to start ... Magnetic monopole - Wikipedia What you describe is certain 'conditions' which act as magnetic monopoles, These same 'conditions' can also be treated as particles. ( like the 'holes' Studiot mentioned )

And this is exactly the level at which testing is mandatory, and 'artificial' doping with testosterone derivative ( performance enhancing ) drugs is flagged and deemed unacceptable. If you have two female athletes, one of which is on hormone therapy ( after reassignment surgery ), and the other is on testosterone based performance enhancers, they will both be flagged by the screening process. The one which is on performance enhancers we, as a society, have agreed should be disqualified. What do you propose to do with the one on hormone therapy? Simply ignore the positive result, as it is in the 'typical' range ? If she ups her dosage the the maximum 'typical' range, so that she is getting her therapy, plus a performance enhancement, is that still OK? If we have rules for testosterone based performance enhancers, we might want to put some rules in place for those receiving those drugs as therapy. Yet even after 4 pages, CharonY, people are still unwilling to discuss any specifics. If

As you have admitted, you have little interest in sports, so I need to make some 'background' explanations. Let's stay with Olympic level sprinting competitions, as Curious has already posted some data on the subject. Ben Johnson, Canadian, and the fastest man alive in 1988, was stripped of his Olympic gold medals in 1988, and awarded to the 'slower' Carl Lewis,apparently because C Lewis' doctors were better able to mask the presence of testosterone derivatives in his urine. All naturally born male, and female, sprinters at these levels of competition are screened for these performance enhancing drugs, yet you are proposng that transgendered sprinters should not be screened because their levels are 'close' to the naturally occurring levels of their reassigned sex. THAT is an unfair advantage. Do they get to skip testing altogether, and we have their 'word' that they are not boosting their levels ? Should we have a set baseline for levels in a typical male, and a typical female, when we both know there is no 'typical' ? Should we have a separate class for athletes who need to boost their levels because of sex reassignment ? I really fail to see how this is not worthy ( or too sensitive ??? ) to be discussed. Do we now just bury our heads in the sand for fear that discussion might 'hurt' feelings ? ( are we aknowledging that certain peoples mental framework migh not be robust enough to handle such discussion, and, that thinking they were born with the wrong sex, is the least of their worries ? )

Don't pick and choose, CharonY. What about the effects of Testosterone and othe banned, performance enhancing drugs ? I see the value in your post, INow, but don't see what it has to do with this topic. Are you saying the 'pack' behaviour of some of us on this forum is similar to the behaviour of those who target, and murder, the transgendered ? Are you saying any of what you posted is any reason NOT to inteelligently and respectfully discuss different classes in certain sports, and how to best apply them fairly to the transgendered ? How long am I 'allowed' to travel down this path of inquisition before I'm accused of 'havng an agenda' ?

Sorry if you got the impression I'm singling you out Zap. I've been part of the 'pack' myself; usually in science forums, in opinion based forums I tend to be the underdog and get ganged-up on. I don't consider this a 'rights' issue. Of course the transgendered have the right to participate in sports. However, if the sport is competitive, we have to find a way of levelling the playing field so that no one has an unfair advantage due to 'artificial' means, such as a surgical/hormonal procedure. This is already done in some cases, and in others has had considerable discussion by the sport's governing body. I'm sure you're aware that testosterone, and specific variants such as HGH and steroids are considered performance nhancing drugs, and are banned in many sports, for the simple reason that they bestow an unfair advantage to the user, and renders the sport uncompetitive. As I'm sure you know that 'Bladerunner', O Pestorius, had a surgical procedure to replace his lower legs ( due to a disability ) with composite prosthetic limbs. There was much discussion about it due to the fact that the prosthetics gave him considerable advantages over runners without. Would that have been discriminating against the disabled, or simply an attempt to make the sport competitive? ( all academic now that he's convicted of murder ) A sex change procedure involves both hormonal treatment as well as surgical proceures. If these treatments/procedures give that person an unfair advantage in that class of that sport, they are making it uncompetitive. That is the argument as I see it. I suppose Curious' over the top Mike Tyson example would be similar to mine if I had used The Six Million Dollar Man ( 80s fictional TV show ) rather than O Pestorius ( Colonel Steve Austin could run at 60 mi/hr ).

But like many other discussions which should take place about some important subjects, this has descended into absurdity, accusations and recriminations, just as quick. If people aren't allowed to voice their opinions without even the chance to explain their point of view, before the 'pack' jumps down their throat, and accuses them of having 'an agenda', how can we possibly have a serious discussion ? Whatever happened to tolerance for others' opinions ? I've voiced this sentiment previously, if all we want from members is an 'echo', then I, and other members, see no need to participate in opinion based forums, as there is NO DISCUSSION.

Maybe I didn't make my point very clear, Ken. What you call 'fossil fuels' are actually the source of many more products that are part of modern life. Plastics being the best known example. They are not only used as CO2 liberating fuels. If you want to consider all associated industry into a product's carbon footprint, are you also willing to consider the added energy/costs of synthesizing raw materials that were previously obtained from 'fossil fuels' due to any future ban ?

Raw just future proofs your image format; if your CCD or CMOS sensor is only capable of 1 Mpixel resolution ( 30 yrs ago ) shooting in Raw will not allow enlargement beyond 3 x 5 inch, while 10-24 Mpixel ( current sensors )will easily allow 14 x 20 inch. I don't do my banking electronically. And incidentally, when you do go to the bank, the teller punches one key, and all your personal information is available to her/him. Why do you trust your bank teller but not your repair person ? ( are you saying all people with some computer knowledge are inherently evil ? 😁 )

I still have CD-Rs from the early 90s that I can read. And I've never used DVD-Ram or Rewritables. Maybe if my business was data storage I would make multiple copies every few years, but some of the programs and data don't even run on current computers/programs/OSs. Which reminds me,other than photos ( although why would I keep photos from my first digital camera at 1024 x 768 resolution ), nobody needs data from 30 years ago; I should 'accelerate' their destruction, and trash them.

With that knowledge, a late 1970s 8bit design like the MosTek 6502 is easy to 'understand'. ( I was partial to the Zilog z80 ) The evolution to 16/32/64 bit designs with MMU/FPU/pipelines/out-of-order-execution/RISC/cache/etc is quite a bit more difficult, and almost impossible for an amateur to implement with discrete logic. If, on the other hand, you just wish to understand these architectures, one source I was fond of using in the 90s, and which is available in most University libraries, is Microprocessor Report. ( not sure if back issues are available online )

That is very observant, but you may be taking the wrong view, Ken. What we call 'fossil fuels' don't just produce fuel. They produce all the plastics and synthetic products that make modern life 'modern'. We just don't see them as bad, because the carbon is 'trapped' in the product, while the actual fuels produced, release CO2 on burning. The amount of plastic and composites used in a modern EV, as opposed to the metal used in a 'big ol' Mercedes' might mean that more 'fossil fuels' are used for actual manufacturing. So fred may be right about that aspect. As an example ... Butene is an organic fuel distilled from 'fossil fuels' in the same partal distillation process that results in gasoline that fuels cars. Yet yesterday I personally reacted Butene with Phosphine at high pressure and temperature in an autoclave, then vented and distilled off any remaining Phosphine/Butene to yield high purity tri-Butyl Phosphine. This pyrophoric liquid is used in the production of Tamilflu, an anti-viral that was in big demand during the 'bird' flu epidemic a decade ago.

I don't like that either ( Canadian Governments do it quite often also ). If the $15 min wage is a good idea, it will stand, and pass, on its own merits. Why attempt to bundle it in with the Covid relief package ? It's one of the games Governments play, if they want to 'sneak' something in that has questionable support, they bundle it with something that everyone wants. If you then object to the questionable program, they can claim you don't support the popular program, and shame you into voting for the whole package, or make you out to be the bad guy. I still have 'questions' regarding the $15 min wage. And I'm not convinced a countrywide min will be equitable. While $15/hr is a very good wage in some of the economically depressed Southern States, it is probably still below the poverty line in places like New Jersy, Massachusetts or California. How is that equitable ? Someone in West Virginia can buy a house on $15/hr, while you are living in a cardboard box with that same wage in Hawaii.

Thanks for the advice, mon ami. We Anglo-Canadians have a complicated love-hate relationship with les Quebecois.

I wouldn't worry much about DVDs being damaged by light/UV. Some of mine are 30 years old, are not stored in boxes, and have outlasted predicted expectation. Most people have switched to online storage for their content now. You should worry more about hammering 🙄 . ( if that hammer slips, goodbye DVD )

Do you Americans have any shame 😋 ? As much as we all like to put down the French, they just convicted former President N Sarkozy of corruption, for trying to illegally obtain information from a magistrate regarding a personal legal action. He is to erve one year, as two were suspended. Yet D Trump is still allowed to speak publically, and possbly incite more insurrections, on top of collusion and bribing of foreign powers, trying to influence State election officials, tax evasion, fraud, disregard for human life, and many others ( not to mention criminally bad hair ). Makes N Sarkozy look like a choir boy in comparison. At least HIS Supreme Court appointees are doing the right thing ( even B Kavanough ) and distancing themselves from him. I guess this is a good example of different 'justice' for the wealthy and influential, in the American system.

Put your 'leachate' through a GC, and find its main components. It will give you some indication of vacuum and temperature you need to vaporize it. Otherwise, pull as much vacuum as you can, and slowly increase the temperature until you have flow. Also check that the condenser is working as it should; if the 'leachate' has a smell, and you get that smell exit the vacuum pump, you are not condensing the vapor.

Meet a lot of Frenchmen, do you ? ( just kidding, most do shower every day ) What bothers me more is breath odour; I don't leave the house without a gargle of Listerine. Sat on an EasyJet flight from Basel to Naples, beside a guy who made me want to ask for a parachute, and jump.

No, I'm saying your ARGUMENT is silly. You are free to report me if you wish.

And for really esoteric methods ... Throwing a mass tangentially around a rotating Blacjk Hole, stealing some of the BH's angular momentum through the frame dragging effect, and having the mass come back with much higher kinetic energy.

Your argument is silly, and easily dismissed. Do you find that personally insulting ? Then, maybe, you should do better.

100% of the surface of the Earth is covered by a miles thick atmosphere. Does the Earth really belong to the fish ? Or to the birds ? That is one of the silliest arguments I've heard in a long time. And what kind of 'new age' jargon is 'balance' ?

I have often found the opposite to be true. A cotton T-shirt will 'smell' after a workout. A synthetc workout shirt will not.

Where, and how, are you 'stuck' ?

I'd have to look for the source, but I thought that had already been verified for gravity 'leaking' into compactified' extra spatial dimensions ( at small scales ). The above ( always ) excellent PBS video provides Gravitational wave evidence for the absence of extra large scale spatial dimensions.
