> [@suranyi](#): > > In 1884 Svente Arrhenius proposed in his Ph.D. thesis that dissolving substances involved dissociation of molecules into paired charged ions. Former chemistry teacher nitpicks and clarification: This is true when you dissolve _ionic_ compounds, not molecular compounds. Molecular compounds do not dissociate in water. (And ionic compounds do not actually contain distinct molecules.) When you dissolve an ionic compound in water, it dissolves and dissociates into ions. The resulting solution conducts electricity (which you can easily demonstrate by experiment and which I frequently did in class). Such a substance that dissociates into ions is also called an _electrolyte_. An example of a molecular compound that dissolves in water but does **not** dissociate into ions is table sugar (sucrose). Sugar is therefore a non-electrolyte and the resulting solution does not conduct electricity. ---

> [@Jeff\_Lichtman](#): > > For years the consensus in medical science was that polyunsaturated hydrogenated oils are more healthful than saturated fats. Do you know what the dates were during which this consensus existed? I just tried a EBSCO Academic Search Complete using access I have to the San Francisco Public Library, and for better or worse, the first thing I came up with was not a journal article, but a Saturday Evening Post article dated Dec. 15, 1962, “Fatty Foods and Poly-Saturated Nonsense.” It says there was then “a cross-current of conflicting claims.” Also: “the Army said it had no intention of changing the GI diet. Reason: Evidence was inconclusive.” The article goes on to, in a mildly approving way, cite the American Heart Association recommending polyunsaturated fat, but also quotes the Heart Association saying there is “no final proof” of benefit. I don’t mean to pick on you, as I could have picked a bunch of other claims in the thread that there once was a consensus concerning some medical advice now discarded. I am wondering if it is in the nature of medicine that true consensus is historically rare. ---

> [@DrDeth](#): > > That “we do not know what causes ulcers”??? yes, even today it is a fact that "stress and lifestyle makes them flare up”. So, ulcers do not fit what the OP is asking for, in fact i can not think of anything that really does fit, once the world entered into the Scientific age. You’re splitting hairs. Scientists and physicians had a consensus as to the _believed_ cause of ulcers (stress & lifestyle). Then, when it was shown what actually causes them, the consensus changed from a belief, to something much more concrete. Same thing with miasma theory of disease and the germ theory of disease. You are right in that once there’s a scientific theory with evidence and experimental proof, they’re very rarely, if ever changed because there’s actual proof that it works. It’s the nature of the beast. But there are often situations where something is imperfectly understood, and the consensus is one way, but upon further research, there is a better understanding and the consensus changes, like @Jeff_Lichtman’s trans fats example. We thought they worked one way, then upon further research, discovered that not only are they not healthy, they’re actively unhealthy. The consensus changed after we better understood something. ---

It was presented for decades that pupating butterflies’ bodies completely dissolve and are reconstructed from the soup. We know now that it doesn’t completely dissolve, although various larval body parts are used as fuel to help complete the metamorphosis. Looks like this thinking is only about 15 or so years old. I don’t know that that’s the case for other pupae, as I’ve only seen this for butterflies. I’ll leave that to some other intrepid researcher. ---

It’s a documented fact (hence, in the movie _Oppenheimer_ ) that Enrico Fermi offered a bet just before the test that the blast would trigger a world-wide chain reaction in the atmosphere. Since he was intimately involved in the project, and knew the numbers, it was more likely just dark humour rather than anything close to a serious worry, the risk was infinitesimal and would mean they missed something really big and obvious in the calculations - which they hadn’t. They knew what the numbers said, and the numbers also said the bomb would work as planned - but of course they still had to test it. ---

> [@DrDeth](#): > > Right, scientists would say “Technically we are still in the end of the last Ice age.” What scientists would say that? We are in the Holocene epoch, which is distinctly an inter-glacial period. CO2 levels tended to vary between 180 ppm at glacial maxima to about 280 ppm at the peaks of inter-glacials. Levels were at around 280 ppm – the typical inter-glacial level – for over 11,000 years prior to the industrial revolution, then started rising rapidly due to anthropogenic carbon emissions. Today they’re 427 ppm and still rising. ---

That quote doesn’t mean what you think it means. We are unquestionably, by any rational definition, in an inter-glacial in terms of the distinct ice age cycles of the last million years or so. What that confusing quote means is that the fact that there’s still ice cover present means we’re not in the totally ice-free greenhouse state that earth was in for millions of years prior to the first glaciation 34 million years ago before the Late Cenozoic. It concerns a vastly greater timescale than what we normally refer to when we speak of ice ages. It has nothing to do with the relatively recent semi-regular ice age cycles of roughly 100,000 year duration. If indeed we ever lost all ice cover we’d have runaway climate change, enormous sea level rise, and likely an extinction event. ---

We are unquestionably, by any rational definition, in an inter-glacial in terms of the distinct ice age cycles of the last million years or so. Confusion and worse can come from a difference between the lay definition of a term and the strict scientific definition. The lay definition of ‘Theory’ is scientifically ‘Hypotheses’. That one has led to no end of misinformation. The lay definition of ‘Ice Age’ is scientifically a glacial period as opposed to an inter-glacial. The old articles talking of a coming ice age were actually referring to the question of whether the next glacial period could be only a few thousand years away as opposed to tens of thousands.

> [@Lucas\_Jackson](#): > > Isn’t it more correct to say the universe appears to be expanding more rapidly and we don’t know why so we’ve called that driving pressure dark energy? Yeah, pretty much. Dark matter is pretty conclusively proven, and honestly it’d be kind of weird if it didn’t exist. All the folks who claim to have models that don’t need dark matter are crackpots. But dark energy is just the currently-popular label for a phenomenon that nobody has any understanding of at all. We know the phenomenon is occurring, but to say that we’re clueless as to why is to overestimate the amount of clue that we have: If anything, we’re negatively clueful. ---

Climate change deniers are constantly slipping a few zeroes on the time scales. Again, good point. The glaciers will not be coming back in our lifetimes, or a our childrens lifetimes. Climate change and overall warming is a fact. Of course, that does not mean that after we- somehow- “fix” the excess CO2, that maybe in a few millennia- it may be time for the glaciers to start creeping back . Or not. We simply do not know as Humans have really fucked the normal climate and cycles. But even if we had not- the glaciers would STILL not be coming any time that would even bother out grandkids. So the glaciers are not coming- the climate change denialists are wrong. Technical definitions can confuse the lay people. ---

> [@Great\_Antibob](#): > > But cabals of such folks (representing “the establishment”) suppressing promising young crusading researchers with their new-fangled ideas, as we might see in movies and as was suggested in this thread re: Alvarez, don’t exist. There is, in fact, one example of such a cabal that hasn’t been brought up in this thread. The subject is New World Paleoanthropology and the theory they supported was called Clovis First. That theory claims that the first humans to enter the Americas was the Clovis culture dating to around 13,000 years ago. Whenever some researcher reported a site that apparently pre-dated that period, the major experts would come up with reasons that the date was wrong. No matter how carefully the researcher collected his data, the cabal would find something to claim it was mistaken. I’m not sure there was any one thing that disproved Clovis First, although the Monte Verde site in Chile was influential. There were several other sites, but perhaps the funeral thing was the most important.
