## Climate science was wrong!

I think it requires a rather profound misunderstanding of how science funding works to make that argument. To explain for those following - say I apply for a federal grant. The whole packet might be 50-100 pages of densely written technical documents. I will probably take me a month or more to put together. It has a 10-20% chance of being funded, and if it's a big one, might net $1 million dollars of funding. My institution immediately takes 55% as overhead. The vast majority of the rest will pay for the salaries of the people I employ. Some will go towards lab costs. If I'm lucky I might get to claim one month of summer salary (for the three months of the year the university doesn't pay me) for 3-5 years. Ergo, I might actually pocket a few thousand dollars at best. On the other side, Ian Plimer - a mining geologist who doesn't even work on climate science, pockets over$400,000 per year from the fossil fuel industry, and "coincidentally" is an ardent critic of climate change. If I'm going to make up data or espouse a false belief for profit, I'm sure as hell not going to be saying climate change is real.

## The post-antibiotics era

In various threads we have (albeit briefly) touched on the fact that resistant bacteria are starting to overwhelm our ability to treat them. Now the CDC has issued a new antibiotic resistance threat report, Basically every 4 hours a new resistant strain is detected and about 35k people die every year due to resistant strains. Countermeasures that have started since the last report came out (2013) were less effective than hoped. Among the biggest threats currently are resistant Acinetobacter, Candida auris, Clostridioides difficile (formerly Clostridium), carbapenem resistant Enterobacteriaceae, and resistant Neisseria gonorrhoeae. There are a lot of issues that have to solved outside the clinical environment, such as reducing or stopping the massive use of antibiotics in agriculture. There, antibiotics are routinely used to fatten animals which results in massive amounts of antibiotics released into the environment and enter the human food chain. Another aspects are procedures in health care (including elderly care) which are often not up to par to limit microbe spread. The challenge is that a single failure can lead to spread through the health care services. There are folks still hoping that we will find an alternative treatment that will be as useful as antibiotics (which we messed up badly) but so far not alternative golden bullet is really in sight (yes there are some developments which can be useful but for the most part they have potential and/or have not shown to be effective in vivo). As a result, it seems that we are indeed moving straight toward the projected post-antibiotic era. Personally (and of course biased by my own research), I think we need to accelerate our understanding of bacterial physiology in order to develop effective countermeasures from the bottom up, as in most cases we only have a very rough understanding how antimicrobial substances actually kill bacteria (which to some extent is also true for antifungals and fungi).

## Oh yeah, I am a pit master!

My parents had 100 acres in the country with an old farmhouse and we'd have a party the whole weekend with lots of friends. We would just dig a pit in the ground for the charcoal and have the pig on a spit, turning it every once in a while. We'd usually have a keg, horseshoes, frisbees, weed, guitars, and it would run from early morning till late at night. Everyone would then crash inside or in tents. Brings back fond memories.

## Safe, non-toxic essential oils?

Of course not. But it means that there is actually evidence of efficacy, even if only for select folks. And it is those trials were efficacy is actually being tested. I.e. if they show that they work (even if only for a subset) it becomes something worthwhile to pursue. I have a professional background in microbiology (with a current focus on infectious diseases) though I have been branching out in aspects of public health . However, I am not a medical professional (such as a dermatologist). But as a whole I am aware that hair loss related to infections is rarer than androgenic alopecia. And within the realm of infections, fungi are more common than bacterial infections. Ketoconazole, as well as other anti-dandruff components can address fungal infections, and have demonstrated relief from hair loss. Perhaps somewhat surprisingly ketoconzole was also shown to be somewhat effective for addressing androgenic hair loss, though only in a subset of people (there are also mice studies, but I am not sure whether it is clear why precisely it works, I have not followed up on that) . But ultimately, the important bit is that there are quite a range of different mechanisms of hair loss and with associated diagnosis (though some can be related). Dermatitis related hair loss requires a different treatment than androgenic hair loss. Both again are different from certain forms of diffuse hair loss, such as telogen effluvium. To have a targeted treatment, proper diagnosis should come first. Edit: I should add that in some studies related to androgenic alopecia folks also often found an increase in certain fungi and it has been suggested that treatment with with antifungal in addition to finasteride or minoxidil (the two components mentioned to treat androgenic hair loss) can be more effective in some patients. However, is not clear what the cause and what the effect is.

## UFO evidence and how it's handled.

Has anyone wondered why most UFO sightings are objects with lights on them? It seems like the aliens want to be seen. If they were capable of traveling the distance to reach us, and they obviously haven't announce themselves, they why would they have lights, even blinking, colored lights, on their spacecraft? Could that be a diversion to allow a more stealthy spacecraft to fly in or out of their Earth bases? Is it possible that if aliens have been hiding here for a long time, they may have learned enough about us, maybe more than we know about ourselves. They could stay one step beyond our ability to detect them. As camera technology improves and becomes more common, aliens would be aware of that, and maybe the aliens have simply become more careful. So only blurred photos are ever taken of them? Also maybe they are very careful to pick up after themselves, so no undeniable evidence is left behind.

## Telepathic Proff

Strange's approach seems good so I'll add to it. I think a detailed definition of "message" is useful. Some notes regarding definitions of message: -Is a message text only? -Can a message be numerical? -Can the message consist of random letters? -Can a text message be delivered in a different language? -Is a message delivered exactly letter by letter? -Will the receiver be able to distinguish "peace" from "peas"? -Does the receiver have to know about the subject or understand the words that makes up the message? -How does the receiver "know" that they have the message? What kind of sensation is triggered? -Is "intention" or feelings delivered with the message? Example: "Now that was just freaking awesome" could be a sarcastic comment or meant as a compliment. Some additional notes to start modeling the phenomenon*: -Is the effect exactly the same for all receiving individuals or are there differences? -What happens at the sending side if there is no individual receiving the message? -What happens with the other people around, will they receive the message? -What happens if you do not know if there is a person in the receiving room? Can you tell? -Can the receiving individual choose to not listen to messages? -Over what range can the message be transferred? -What happens at maximum range, are some parts dropped? Some messages are not transferred? Other? -Are some recipients are more sensitive, receiving messages at longer distances? *) I'm of course completely convinced that this (and other) experiments will fail, telepathy does not exist. But discussing pros and cons of possible approaches is interesting.

## Telepathic Proff

What experiments are you talking about? And if you don't know, how do you know you can "prove" it? You should forget about "proof", and concentrate on how you can provide evidence of your claims. The more evidence to support it, the more persuasive your argument will be. Define EXACTLY what you mean by "I can do telepathic ability". Define what you mean by "send messages directly mind to mind". The most important thing at this stage is for you to decide what would show your claims to be FALSE. What test failed, or what message not sent would show that you CAN'T do telepathic ability? Your claims need to be capable of falsification before we can take them seriously. Once you can do that, then you should be able to take any standard test for ESP, using validated methodology. They'll be looking for results that go beyond statistical anomaly. Or if your definitions are different, perhaps then someone could suggest a way to test them. Based solely on your OP, I would expect you to be able to send a random phrase as a private message to one of our staff members, then send the same phrase directly to my mind with your telepathic ability. When the staff member and I confer, I should be able to tell them, "Blue peninsula hopping trousers twisted badly", and they should be amazed that I said the exact same phrase as you. That's when everyone here suddenly becomes very interested in your thread. Got anything like that?

## What exactly is happening when something is lighter than anticipated?

Unless you expect it. Castles were built with staircases with an "odd" stepp in them to trip enemies who were climbing the stairs. I learned about this interesting fact in a talk about the safety of modern stairs where , as they pointed out, badly made stairs are still killing the unwary. Here's a trivia question for you ( the answer is at the end of the post) Roughly how many people are killed by falling on stairs each day in the UK? Interesting fact for the day. If you have a staircase where the steps are uneven you can always make it even by adding planks (of various thicknesses) to the steps. This is an important result because adding to the treads is easy but taking stuff away is hard. It's also (I think) always possible to make all the steps the same "length" as well. So there really is no excuse for badly built stairways. (About two, btw- did you guess right?) Our brains are pretty good, but we often rely on reflexes which don't use the brain. I'm not sure which category this phenomenon falls into . I'd be interested in finding out. I'd be even more interested in knowing how they found out.

## What exactly is happening when something is lighter than anticipated?

What is described is somewhat related to an interesting phenomenon called the size-weight illusion. It is a multisensory phenomenon in which, roughly speaking larger objects feel heavier, even if they are not. The interesting bit is that these studies look at the interaction between feedforward (anticipation of weight) and feedback information. In the case of OP it is fairly clear, the discrepancy between anticipated weight and experienced one is large, and as such the feedback mechanism cannot cope with the excess forces (the jolt may be a surprise reaction due to the perceived discrepancy). However, in cases where, for example two objects of same weight but different size are presented, the muscle stiffness may be different before lifting the object (as the feedforward mechanisms anticipates that the larger object is heavier) but then the feedback kicks in and adjusts closer to the actual weight. The perception, however, is still that the larger object is actually heavier. It should also be noted that anticipation is common to basically all animals with an CNS, not only to arboreal ones, as relying on feedback mechanisms is typically too slow for most dynamic situations. For example, catching a ball requires anticipation of its flight path. Some simpler animals have faster feedback loops in which locally for example legs convey information regarding the status to other legs, without need for central coordination. But even then in hunting spiders one has found evidence that they may anticipate to some degree anticipate prey behaviour.

## Fractal Physics

I've been exploring fractals as part of a rather long term philosophy project and have had a good deal of success modeling the simplest structures of my system with the folded geometry of the mandelbox. In addition to meeting the logical constraints I've established it seems that the geometries of the Mandelbox are capable of recreating nearly every photo and representation of quantum holography I've come across. I've also found that generating interference patterns within the fractal allows me to model dynamic processes and larger scale concepts in physics like gravitational lensing, gravitational waves, fresnel distortion and general CAS emergence. You can see all of these properties in motion at my youtube channel url deleted This video is a general preview of my work. url deleted I would love some feedback on these findings, some representations are more obvious than others and the interference based visualizations are difficult to see with youtube's compression so larger resolution representations are linked in the description. Thank you for your time, I hope you find these useful

What are you trying to do here? Equation 1 is an unusual way of writing the standard equation of a circle x2 + y2 = r2 (note you don't need LaTex to write this, just use the sub and super script icons on the text input editor, labelled x2 and x2) your way puts you into immediate trouble since if D is the diameter D = 2r so equation 2 becomes $\frac{C}{2} = \sqrt {{r^2} - {{\left( {2r} \right)}^2}} = \sqrt { - 3{r^2}}$ So you are trying for the square root of a negative number. Furthermore if C is the length of the circumference, you can't just replace y with half of it.
19. 1 point

That is not the equation for the circumference of a circle. That will give you the y coordinates for the (two) points on a circle (with radius r) corresponding to the given x value. You could, perhaps, integrate over a range of x values to get the circumference but it seems unnecessarily complicated because: C = 2 pi r

## Impeachment Hearings

Slightly beside the point, but in some ways this thread seems like a microcosm of what postmodernist philosophers have predicted since the 80s. Instead of a common meta-narrative, knowledge is fragmented and used as a commodity by various actors (Lyotard refers specifically the issues of computerization and who determines which information is stored and disseminated- a thought that can be easily extended to tech companies as the new gate-keepers of knowledge). While we are dealing with exactly the same event, the associated strands of knowledge appear to be very different, resulting not only a different viewpoints, but in fact in parallel strands that do not cross over. It reminds me a bit on the concept of Language games where players agree to use certain rules to create meaning from uttered words. In the postmodernist world, according to Lyotard, we have created many parallel language games, each of which are legitimized by their respective institutions. So we may have politically affiliated language games, in which certain fragments of information carry entirely different meanings and which are self-referenced and amplified by the use of different communication channels (say, social media). Even when we discuss the same things on this board, we arrived to our conclusions using different lines of information. There is ultimately not thinking for oneself, unless one plays the solitaire equivalent of a language game.

## The Square Kilometre Array

As some of you probably know, the Square Kilometre Array will become the biggest radio telescope on Earth, with a collecting area of 1 square kilometre. The construction will start in 2021 and the first light is expected to take place in 2027. It will cover the frequencies from 50 MHz to 15 Ghz. But what I wanted to share with you guys is a new study about how far the SKA can 'listen'. A recent study points out that the SKA could detect extraterrestrial airport radars 200 light years away.

Isn't techology wonderful when it works ? Until it doesn't. I see there was a glitch in my last post. The scan gave you the correct equation (Newton's second Law) for the acceleration, but was cut off at the knees. My edit/correction I see missed off the acceleration completely. Sorry. So here we go 4F = W/g times acceleration or acceleration = 4gF/W So now we need to find a value for F. Which is why we need a free body diagram for a wheel ?

## Blob Theory

Whilst I am not unhappy with the framework idea in your description - There are plenty of pictures of multidimensional 'singularity' arrays on the net, but I find one or two inconsistencies between your OP and later statements. Madelung theory is about as far as you can get from unreactive since it is basically the sum to infinity of multiple (but diminishing) charge interactions. Pilot waves are less interactive, but they carry momentum and are neither singularities nor asymptotic. I see no connection here. You also need to explain why pressure makes any difference to something that is absolutely unreactive. As an alternative to a multidimensional array of needles, you might like to look at Cantor Dust https://www.google.co.uk/search?source=hp&ei=WXfOXcv-H46mUIm7hdgH&q=cantor's+dust&oq=cantor's+dust&gs_l=psy-ab.3..0j0i22i30l7j0i22i10i30j0i22i30.846.3822..4576...0.0..0.300.1868.6j3j3j1......0....1..gws-wiz.......0i131j0i10.uOpLkawVaVI&ved=0ahUKEwiLj4fl-uvlAhUOExQKHYldAXsQ4dUDCAc&uact=5

## Climate science was wrong!

Trust is not the same as faith. Trust in the institutions, practices and ethics of science is not religion. Given that the work of scientists is documented and widely accessible it is available for sceptical review and critique - but this takes knowledge and expertise. Being wrong is bad for a scientist's reputation - and when they are wrong it is documented. There are sound reasons to have trust in the error correcting nature of those practices and - because it is so thoroughly documented, misconduct or conspiracy is difficult to sustain. If, as a sceptic, you don't actually engage in actually doing the work of critiquing - which involves studying, in this case, climate science - any conclusion that it is wrong is a mere personal preference, a belief that lacks any sound basis. It is not up to people who trust science based advice to convince the doubters, nor the scientists either; it is within the body of their works that scientists present the evidence and reasoning. Meanwhile, as the initial post notes, we are experiencing weather events that are in keeping with a world with AGW. I suggest that when examined closely these are within the range of what climate model based projections have "predicted" - the middle of the spread outcomes may be being exceeded. That doesn't make it wrong any more than outcomes that are at the high end of the range not occurring - the worst case ones that, rightly and wrongly get extra public interest and attention - makes climate science wrong.
