Neil deGrasse Tyson - Science in America

dag says...

Comment hidden because you are ignoring dag. (show it anyway)

I love science.

Also good to remember that it's corruptible too. Despotic leaders get dissidents declared mentally ill.

Going farther back a kind of science brought us eugenics.

Science is often a victim of orthodoxy. Bad science becomes "common sense" way too easily. Just off the top of my head, telling parents not to feed their babies peanuts may have caused thousands of cases of peanut allergies. https://globenewswire.com/news-release/2017/04/14/960387/0/en/Pulling-the-Plug-on-Peanut-Allergy.html

Doubt - How Deniers Win

newtboy says...

You gave a few examples, I did not ever disagree that it happens, I disagreed that it's happening today in Africa (or worldwide) at a level that's worse than the lack of water on a global scale. I will concede that, in certain areas, it is, but worldwide, even continent wide, it's less of an issue than useable water by far.
You give up pretty easily.
Historically, there have not been 'men with guns'. Guns are a fairly new construct. If it were historical fact that men with 'overwhelming force' (so forget the guns quip) drive farmers out of farming, why are we still here farming?

Yes, the two statements about technology are not mutually exclusive...your point? You 'give up' a lot.

Yes, and I clearly stated I believe they ignored some factors to get their numbers, as most 'predictions' I've seen in the last 20 years have done. I also clearly stated that even their lower range numbers were disastrous and unsurvivable and their high numbers even more so, I just went on to say my educated guess is that they are likely also on the low side because they don't account for everything AND they assume we'll stop rushing to make things worse at some point. I just think that's wishful thinking, based on my estimations of human behavior.

I do listen to fact, reason, data, hypothesis, innuendo, lies, insanity, and more (proven by the fact that I'm still here discussing this, and it's funny that you now wish to no longer 'listen' to facts or reason yourself because you 'give up'), then do my best with my degree in science and scientific mind to work out what hypothesis is closest to the data, and see if I can determine where it's imperfect and why. You can call it 'personal belief', I call it educated guess work, because I've paid attention and most models were on the low side of reality because they don't include all factors (they can't, we don't know all factors involved yet to program them into the models) and because they all expect humans to stop adding to the problem at some point in their equations, which I say from experience is wishful thinking and bad science/math, and I think it's nearly always added to actual science lately for political reasons on one side or the other.
EDIT: For instance, I've never seen a model that includes 'global dimming', but it's a factor that has kept up to 3 degrees C of warming from happening. it happens when particulates in the upper atmosphere deflect sunlight, stopping it from entering the system as light or heat. It has also added to a decline in global food production, but I've yet to see a climate study that includes it in their model. If we shut down all coal plants and combustion engines tomorrow, we would see a rapid spike in temperature as a result, another thing no one ever mentions.

I note you aren't defending your 'facts' about Texas producing more food than California, were you as certain of that as you are about these 'facts'? If so, perhaps more research could be warranted?

Oh, never mind, I forgot you decided to stop listening to facts and hypothesis and give up. I think your children would be disappointed you care so little about their future....I have none, so I have no dog in the fight. Nothing done today will effect things either way in my lifetime. As I see it, that means I'm one of the few with no agenda either way, I'm only interested in reality, and the data I have seen has consistently been worse than the worst predictions when everything is considered in totality (not cherry picked).

This is getting old.
If production were simple, ie not requiring extra water and fertilizer, everyone who's hungry would farm, and there would be 'bush taca' (wild food) to gather and eat. You can't make a living stealing from subsistence farmers, you go hungry between farms that way.
I point out that historically you are wrong. I cite specific examples illustrating that you are wrong. Still you come back insisting that somehow men with guns can't starve people out who want to farm. That somehow the mass starvations under Stalin, Mao, and North Korea weren't even related to the mass theft at gunpoint of farm crops and land from farmers. You insist that it's not what is today stopping farmland from productivity in places like the DRC, Liberia, Sudan, Somalia, Yemen, and many more. I give up.

the tech to replace oil and coal and gas exist today
But also
we can't get to the moon with NASA today, or get on a concord
I give up.

78% less glacier doesn't mean ...
I think those numbers are small, and it's likely that there will be less than 22% of glaciers left in 100 years
I cited the actual science from the IPCC with their own projections. You take the very, very worst of the multiple scenarios the IPCC run. Not content with that, you take the most extreme range of error within that extreme scenario. Not content with that, you then inject your PERSONAL BELIEF that even that position of science is likely to optimistic.

I give up. If you refuse to listen to fact and reason that's up to you. Just don't pretend your any better than the other side ignoring the actual science just from a different end of the spectrum.

Bill Nye: You Can’t Ignore Facts Forever

dannym3141 says...

Another great source from ChaosEngine's link. This actually has a drop down menu that allows you to select any part of the scientific report, or a simplified summary for non-technical people.

There is an absolute wealth of clear and hard scientific information in there. If you find a problem with any of the science then i highly recommend you write your own paper about the problem and submit to have it peer reviewed. I think it would be a great lesson for @A-Winston and @lantern53 both to go through the peer review process and see how easy/hard it is to submit incorrect science. And also to see how bad science is treated - not with insults, or rage like the internet community, but with simple facts and evidence like a professional community.

Bill Nye: You Can’t Ignore Facts Forever

dannym3141 says...

@A-Winston @lantern53

Have you ever heard of the Dunning-Kruger effect?

I'll simplify it for you - those who are not well educated in a subject greatly overestimate their ability at the subject, because they don't know all of the things that they don't know.

Those who are better educated in a subject greatly underestimate their ability at the subject, because they know how complicated it is.

Now you two don't know about science, and that's ok - that's not an insult and i don't want any of this to be insulting. But it is meant to be a reminder that you are talking about one of if not the most technical and complicated abstract subjects that we as a species pursue. If you don't even understand the "scientific method" (a distinct term) and how the "scientific community" (another distinct term) works and comes to consensus, how can you possibly hope to decipher fact (science) from fiction (propaganda)?

I keep having to post this, but i'll do it again. The scientific community is made up of all kinds of people such as university lecturers and students (yes, your kids might be part of the community), amateur scientists, people at research institutions.... anyone who cares enough to approach things methodically and systematically, anyone interested in finding out as much as we possibly can about everything we can. Real science does not get paid based on results - the funding is provided for the research and the research finds whatever it finds. You can't lie about science, because other anal bastards (far worse than me) are just waiting to find something wrong with it and pillory it. That's how the scientific community works, it's like internet comments only worse. You can't get away with doing bad science for long.

Most people in scientific research do not have a lot of money, do you understand that? I can tell you right now - i contribute to scientific papers and such, so that makes me part of the scientific community. I'm just a post-grad student living on a student loan and doing something that i enjoy. My lecturers make a living, but they are not well-off by any means. We also suffer tax when politicians take our evidence and twist it in front of our faces. And we're left standing here, exasperated, wondering why you'd listen to non-experts over experts. If your doctor said you had diabetes, you wouldn't ask a politician to confirm it? If you want a scientific opinion, consult the scientific community.

I would love you to ask yourself the following question; "What do i really know about the scientific community and the scientific method?" Because if you took half an hour one day to go to an accredited university and ask the science department about how science works, how consensus is formed, and what makes good scientific practice, you'd be able to rid yourselves of these myths that somehow all scientists (i.e. average people, doing scientific research for the sake of science) are in some kind of club or gang or being paid to say that humans are causing climate devastation. The reason the majority of people say that is because the science speaks for itself and is not open to interpretation. The facts are facts.

Are you really thinking this through?

I want to show you one final thing, and it comes from the wikipedia page on Scientific method (which i recommend you read to avail yourself about which you speak, please don't speak from ignorance).

"The chief characteristic which distinguishes the scientific method from other methods of acquiring knowledge is that scientists seek to let reality speak for itself, supporting a theory when a theory's predictions are confirmed and challenging a theory when its predictions prove false."

The science speaks for itself, and i recommend you start listening to real scientists. Why prefer the opinion of a few individuals who are either flawed in their scientific reasoning or flat out being paid to lie? The scientific community is in full agreement.

Edit: Sorry for the long post, but you're talking about something you don't understand and it exasperates me. You wouldn't come here and talk about the details of internal medicine, but you're quite happy to tell a scientist, to his face, that he doesn't know science.

@Trancecoach - they respond in literature all the time. A scientist's response is to prove it, scientifically. They do, and are, all the time. But most people do not understand science and those that do still find scientific papers daunting and difficult to follow. People like the two i mentioned above, they don't have a hope in hell of understanding the source of the information, and they sadly look to the wrong people to explain it to them.

Prospect - The Best Low Budget SciFi Shortfilm I've Seen

newtboy says...

Which 'liberal anti-gmo stance' do you speak of? Many have been presented that could fall into those categories if not read with care.
Does 'pro-responsible science' count as 'liberal anti-gmo'? Does anti-experimentation on the public in secret count? If so, mea culpa.
I see them as different stances though. I'm not 'anti-gmo' as such, I'm anti-secrecy and anti-bad science and anti-false propaganda. If gmo's are made safe to use, labeled to aid in informed choice, non-transferable to other non-gmo crops, and are proven so by neutral, repeatable (and repeated) science, I'm fine with them. That has not happened yet.

Oh liberals and their anti-gmo stance, just about as irrational as any conservative anti-science position, bedfellow to climate change denialism.

Michio Kaku: Can Nanotechnology Create Utopia?

It's not a science video...

Oh please, this is just bad science. It's barely even worth cheap sci-fi. Where do you get the energy to run the replicator, eh? Does entropy ring a bell? Even without replicators humans are draining the earth of it's energetic resources (including the "sustainable" ones)...
Nice philosophical mindgame, like all utopias for that matter, but nowhere near hard science.

Our world is full of achievements that were once beyond the ability of hard science.
How can humans possibly communicate over hundrends of miles? We're already yelling as loud as we can.
How can we possibly run faster than cheetahs? Our legs can't move any faster!
How can I kill Og standing all the way over there? Rock not throw farther!!!

Ultimately, all life shares one common goal; the quest for energy. From single cell creatures harvesting light, heat or chemical reactions to survive...all the way to modern humans with their agriculture, technology and complex social structures; the journey of evolution has been the race for more efficient means of acquiring and managing energy.
Our economies are elaborate means of trading energy.
Our societies organized to maximize the collection of energy.
Our governments created to ensure equitable distribution or energy.

The result of millenia of advancement is that we now expend much less energy to acquire a larger return of energy. And all that excess energy creates the complex world we live in.

But there is the potential, in the future, for technological advancements in science that will create a massive paradigm shift. There is the potential for accessible energy to become inexhaustable. And when the cost, in terms of human effort, of energy approaches Zero....everything changes.

Will the end of human need result in a utopia?
LOL...never. Because we'll always have griefers.

Tim Keller Speaks of God, Evolution, Dawkins and Faith

silvercord says...

Wow. I'm not here to argue whether or not evolution is true or not; thought I was clear about that. You're welcome to it over at talkorigins.org I, for one, don't think evolution is falsifiable since it isn't reproducible. I didn't say it didn't happen. Just that it isn't falsifiable. I can find evolutionists who both disagree with me and agree with me. It's just my position. Since the scientific method requires experimentation to prove the theory, well, I think there is a problem there. You don't. OK. I'm good with that. >> ^PalmliX:

You can't apply the scientific method to evolution!?!? How exactly do you think the theory has come to exist? Without the scientific method there would be no theory of evoloution.
Of course the scientific method is in the hands of imperfect human beings, we created it, who else's hands would it be in? Yes humans are imperfect and that can sometimes lead to bad science, but the answer to bad science isn't no science, it's more science.
Should we just give up on science all together because humans aren't perfect? How else do you suggest we separate fact from fantasy? Truth from fiction? I really find your philosophy troubling because it seems to suggest that since we can't know everything, right away, perfectly, that we might as well not try?
Also I really don't care about some inane argument Dawkins made that has now been refuted. As I've said before, he's just one man and at the end of the day his opinions really don't matter, his thoughts on evolution in no way change the facts of evolution or the validity of the scientific method in general.
It's a silly semantic game that you play when you say 'I didn't hear Keller say there is or isn't a god, or evolution is bunk' etc... Yes he didn't use those exact words but the larger issue at hand is the same and you know it!
Finally, evolution isn't falsifiable? I stopped taking science after grade 10 and I can already think of a couple ways evolution could be falsified. For example, if we found an organism that couldn't have been formed from the evolutionary process, or if we found the fossil of an animal that existed in a time that would have been impossible by evolutionary predictions. I'm sure biologists have come up with a lot more.
>> ^silvercord:
In this clip I don't hear Keller say there is or isn't a God. I don't hear him say that evolution is bunk or not. I hear him saying that Dawkins argument is spurious for several reasons.
As I understand it, the scientific method requires that something must be falsifiable; evolution is not. I'm not saying evolution doesn't happen, just that you can't apply the scientific method to it. Also, the scientific method is always in the hands of humans. That is the fly in the ointment. Humans are hugely fallible. The method may be perfect, but the handlers aren't.
I think it would be beneficial to watch the entire talk so that Keller isn't being made the problem for pointing out the problem. There is a problem and it isn't Keller or me. It isn't you either. It's the fallibility of humans not being taken into account in this equation.

Brian Cox: it is not acceptable to promote bad science

rebuilder says...

>> ^ponceleon:

Don't have time to see the whole thing now, but I feel like the new challenge for journalism in the information age is that they need to understand that freedom of the press is not freedom to report without checking facts. Sensationalism is the rule rather than actual reporting. In an age where "reality" TV is scripted and caters to the lowest commmon denominator, as a society we have to hope that this too will bounce back.
If anyone saw last night's South Park, it was pure brilliance. We just need James Cameron to come in and raise the bar dammit!


Journalists work for money the same as most folks. Good journalism in the sense you're talking about takes time, and therefore is expensive. Furthermore, balanced, dry articles about the nuanced nature of the world around us don't lend themselves well to attention-grabbing headlines, a problem perhaps exacerbated by the need for page views and the ability to track, per article posted, what people view most.

I mean, really, what are more people going to want to read - or rather, see - "Higgs Boson identified with high probability" or "Lady Catherine caught with her tits out - photos inside!"?

We've conflated information with entertainment. I wonder how to turn that particular tide back.
