Welding in Space

oritteropo says...

Since I quite enjoyed the talk I'm willing to overlook that fact He did also have some good examples of actual cold welding.

NASA has an interesting lessons learned article about the Galileo high gain antenna failure, which also seems to be more nuanced than "it was cold welding" - http://llis.nasa.gov/lesson/492

p.s. I got curious about the reference to Gemini, and I'm not 100% sure but I think it might come from a 1991 paper "On-Orbit Coldwelding Fact or Friction?" by Dursch, H. & Spear, S. (Bibliographic Code: 1991NASCP3134.1565D) or else it's from the paper it references as ref 5 (I. Stambler "Surface Effects in Space", Space/Aeronautics, Vol 45 No. 2, 1966 pp. 63-67).

That paper gives the opposite impression to the start of Derek's talk, rather than cold welding being discovered around the time of Gemini, it was often thought to be a problem around that time but as he says later was subsequently found to be quite rare (Dursch and Spear found no actual cases of cold welding causing spacecraft issues, they were usually friction issues due to fretting or galling caused by loss of lubricants, but still recommended taking precautions to avoid coldwelding).

Wait...

Uses an example of cold-welding to set the premise for the talk.
Psych! - Example was not actually cold-welding.

His second example, the Galileo Jupiter mission, didn't explain why we *thought* cold-welding was a result of a malfunction, and I've no idea how that information would come about because the craft never returned to earth.

wtf? Are these shows really getting so bad? I had more respect for this guy.

An historian's take on what went wrong with Islam

poolcleaner says...

I think it's just easier to simplify an argument when it's part of another society. Even George Saliba criticizes western civ by simplifying Copernicus, Galileo, and others into monopolizing crooks; something he warns his own, "morally just" Islamic society against.

Both Neil and George are railing against each other's society whIle acknowledging a truth.

Always good to hear both sides, and one from an actual historian, but honestly, none of this is news. Any time someone says "this" is why this happened, it's safe to call bullshit until you've seen a multitude of angles (deduction). It's like debating the multitude of reasons for the fall of Rome or the start of WWI. Nothing in history truly repeats itself because it's so convoluted there's rarely a single cause for rises and declines. It's just easy to find a historical pattern and then hold onto it as THE pattern of history and exclude things that are contrary.

The War on Science

Lawdeedaw says...

Galileo was sentenced to house arrest because he was a dickhead...the official "reason" they used was null because the church was starting to come around to the idea of the science...however, coming around should not be implied to be "close to being accepted..." Worlds apart...

Neil deGrasse Tyson - "Do You Believe in God?"

Grimm says...

A simple "no" does not allow the man to drop some knowledge though. A simple "no" does not cause anyone to possibly rethink their position.

I don't think NDT thinks he is going to convince anyone that their religion is false. He probably feels his time is better spent trying to get people to stop rejecting science just because it might go against or does not support their religious beliefs and that science does not have to be the enemy of their religion.

He never said "religion tells you how to get to heaven". He used Galileo as an example of how one can keep religion and science separate....how what they believe or are taught "how to go to heaven" vs "how the heavens go".

Yes....it is superstitious bullshit from A to Z. But if the man answers the question with "NO, because its all superstitious bullshit"...the only people listening at that point are the people that already agree with that statement.

BicycleRepairMan said:

A simple "no" would also work.

Religion tells me HOW to go to heaven? Really does it now? What heaven? how? Whats religion´s method? if two competing religions has different ways of getting to heaven, or even outright contradictory hows(Such as Islam (No heaven for you if you believe in Jesus) and Christianity (No heaven for you if you dont believe in Jesus)), how the fuck is that a "how" at all? It isnt. Its superstitious bullshit from A to Z.

Bill Nye: You Can’t Ignore Facts Forever

Trancecoach says...

My doctorate is in psychology -- a social science, which includes coursework in epistemology. I am also the executive director of a peer reviewed psychology Journal which incorporates quantitative, qualitative, and mixed method methodologies.

If science was driven purely by consensus, than the upending of long-held scientific understanding (as achieved by the likes of Galileo, or Darwin, or Einstein -- who, incidentally, upended some theories about how something as "self-evident" as gravity works -- in more notable ways and by lesser known scientists in still significant ways) would never come about. Science is not practiced by "votes," whereby the majority determines what theories are most accurate. Rather, evidence (whether it be rationally deduced, rationally induced, empirically demonstrated, or hermeneutically interpreted) serves as the basis for scientific progress, whether the majority of scientists agree with it or not.

(Climate change, itself, is rationally deduced, since empirical models of the earth are so difficult if not impossible to design, let alone run controlled trials.)

You are actually going a long way to make my point that those who are "believers" in climate change are missing the value and indeed necessity for ongoing skepticism in the scientific literature (rather than the name-calling and vilification that constitutes much of the "OMG! Climate Change!" discourse of late). That point, along with illuminating some of the citations I linked to above, is the purpose of my comment -- and not to argue (or name-call or "debate" as many on the sift waste their time doing).

I do concur that the manner in which I posted the links may not have been "fair," and so I apologize for that, but the content of the links themselves raise significant questions as to the unilateral "belief" in "OMG! [andropogenic] Climate Change!" I encourage anyone who is seriously interested in the scientific basis for skepticism around such a belief, to consider reviewing the literature cited in those links before arriving at an incontrovertible conclusion.

But in light of your request for a single link, I recommend you visit the NPCC's website and perhaps attend, specifically, to their literature about temperature changes (PDF), which I believe serve as valid refutations of the literature upon which the climate change "believers" tend to base their adrenal-freakouts.

The Amazing Randi busts "Magnet Man"

J-Rothmann says...

German Channel ProSieben - Galileo featured Miroslaw Magola who promotes Telekinesis. Real Magneto, X- Men, Miroslaw Magola's telekinesis is achieved by projecting a portion of his consciousness in the object that he want to move.

Theoretical physicist Michio Kaku : THE FUTURE OF THE MIND: The scientific quest to understand, enhance, and empower the mind.” And his quest to promote: “Telepathy. Telekinesis. Mind reading. Photographing a dream. Uploading memories. Mentally controlled robots.”

Kaku claims all of “these feats” have already been achieved. “These feats, once considered science fiction, have now been achieved in the laboratory, as documented in THE FUTURE OF THE MIND,” Kaku’s website declares.

Kaku notes that his “book goes even further, analyzing when one day we might have a complete map of the brain, or a back up Brain 2.0, which may allow scientists to send consciousness throughout the universe.” Miroslaw Magola alias "Magnetic Man," ( Magnet Mann ) known form Stan Lee's Superhumans - MInd Force who allegedly exhibits telekinetic powers aired on History and Discovery Channel born in Poland and now living in Germany. He claims he can lift objects off the floor, transport them through the air and force them to stick to his body - all using the power of his mind .

He was investigated by Prof. Dr. Dr. Ruhenstroth-­Bauer and Dr. Friedbert Karger of the Max Planck Institute and Dr. David Lewis (psychologist), a neurophysiologist at MindLab, one of the United Kingdom's leading neuro-research centers and Dr. Konstantin Korotkov, professor of Physics at St. Petersburg State Technical University in Russia and Alexander Imich from USA.

Last Week Tonight with John Oliver: Climate Change Debate

Trancecoach says...

To be sure, it does not take "studies" and "experts" to "prove" that smog turns healthy breathable air into unhealthy unbreathable air.

But, again, the consensus among proponents of man-made global warming pretty much all agree that the cause is greenhouse gases. And the consensus is also that cattle accounts for the main source of greenhouse gases. I honestly don't see how anyone concerned with man-made global warming can ignore this and, therefore, not be vegetarian (i.e., be congruent in their behaviors and beliefs).

I recommend reading "Hot Talk, Cold Science", endorsed by respected physicist the late Frederick Seitz, William Harper professor of Physics at Princeton, Richard Lindzen, meteorologist at MIT, written by physicist Fred Singer.

If you want to know where Prof. Singer is coming from, read this (and skeptics are not "deniers"- that's just a slur).

But before you freak out, let me restate, it matters not; clean air is good either way; do things that contribute to clean air (like end the state -- > good luck with that!).

(Better to read and have these discussions with actual working climate scientists than to bother with Internet pundits either way.)

There is also "consensus" as to the three types of "deniers." If anyone calls me a "denier," I'd be curious as to which of the three types of "deniers" you think I belong to (as indicated in the Singer article linked above). And you can then give me your scientific explanations as to why my stance is not valid.

This is something worth keeping in mind (from Singer):

"I have concluded that we can accomplish very little with convinced warmistas and probably even less with true deniers. So we just make our measurements, perfect our theories, publish our work, and hope that in time the truth will out."

The warmistas matter as much as the deniers. And the bottomline remains: what are you going to do about it anyway? As has been shown over and over, your "votes" don't count for much (or anything at all). So, what are you going to do about this (other than fume and get your panties in a twist on videosift)? The same is true with the "deniers." And the skeptics (i.e., true scientists).

Science also doesn't work by consensus. No real scientist will say otherwise. You either prove/falsify some hypothesis or you don't. You don't determine the truth in science by "consensus." Scientific consensus, as has been said, is itself unscientific.

There is no "consensus" on the acceleration speed of falling objects. There is no "consensus" on whether the Earth is orbiting the sun. There is no "consensus" on water being made up of H2O. These you can measure and find out for yourself. (In fact, Galileo had less than 5% "consensus" on whether the Earth orbits the sun at the time of his experiments. Facts matter. "Consensus?" Not so much.)

But,

“If the science were as certain as climate activists pretend, then there would be precisely one climate model, and it would be in agreement with measured data. As it happens, climate modelers have constructed literally dozens of climate models. What they all have in common is a failure to represent reality, and a failure to agree with the other models. As the models have increasingly diverged from the data, the climate clique have nevertheless grown increasingly confident—from cocky in 2001 (66% certainty in IPCC’s Third Assessment Report) to downright arrogant in 2013 (95% certainty in the Fifth Assessment Report).”

Still, this does not in any way equate "denial" of man-made global warming or whatever other "climate change." That is simply an unfounded conflation made up by the propagandists which so many here take on as gospel.

And it still does not let anyone "off the hook" about actually doing something that matters if you care about it so much.

Let me know if anyone finds any "errors" in the science of the NGIPCC articles and studies that I posted above.

How Inequality Was Created

Trancecoach says...

@enoch, I didn't see your response to me since you didn't "reply" to me, or "message me" ("@Trancecoach"), so I'm just seeing this now:

> you argue like someone who has found religion.

What is this, then, if not ad hominem? What has religion got to do with economics in this context? I'm willing to change my mind, if you can show me the flaws in my argument.

> and its not just you that never wants to address the dark side of capitalism.

So, please tell me what didn't get 'addressed?' Did I not respond to every point in your post? Where are your replies to my reply?

> disciples of free market capitalism never want to talk about their deformed child
> locked in the upstairs bedroom.out of sight..out of mind.

Again, what wasn't addressed? Free market capitalists love to talk about free market capitalism. Ok. So are you stuck on this such that you're unable to read/respond to my response?

Seems to me that you're projecting, because while you say that my responses are like a 'sermon,' this portion of your post actually sounds like a sermon:

> every system has its flaws.
> both positive and negative.
> and no system is a rigid single dimension but rather varying layers of slight
> differences.
> this includes every political and economic system thought of or just living in the
> realm of dreams.
> it is through discussion with people we may disagree in which new ideas can breed
> and grow.
> this was my ultimate goal in talking with you.
> instead i get a sermon.
> hope has two daughters.
> anger and courage.
> anger at the way things are,and courage to change them.
> i havent had a beer in ten years.
> gonna go grab me a beer or two.
> what a silly,sad old man i have become.
> old men should stop dreaming.....

Let's not degrade the level of discourse to ad hominem or sob stories. If you need help, ask for help. But don't blame me if you relapse. We are all accountable for our own thoughts, feelings, and behaviors.

> old men should stop dreaming

Dream all you want, but don't expect everyone else to take your dreams seriously just because you say so. (Why not address any of the points I made in my response?)

"The best argument against democracy is a five minute conversation with the
average voter." ~ Winston Churchill

I'm at a loss as to what response I can give you that would 'appease' your sensibilities? As far as I could tell, all of your questions were addressed. But you ignored my reply, and went back to "no one wants to talk about it" or whatever. So, what can be said?

It seems like you don't really want to "debate" or "converse" or whatever. If I refute your arguments, then you interpret that as meaning that I don't want to talk about it. Did I get that right? That doesn't make much sense to me. If not, please explain what I am missing here.

Also, what does it matter if you are old or young, or a dreamer or not, in terms of getting to the truth about socialism and capitalism?

> but you are blinded by dogma.

If so, why not show me what part of my argument is dogmatic or not epistemologically sound?
For example, what specifically about the right to and/or preference for non-aggression is 'dogmatic?' I don't like being bullied, so does that make me dogmatic? What about the impossibility of economic calculation under any sort of socialism is 'dogmatic?' And how so?

If someone doesn't understand calculus, they might call it 'dogma.' But if you understand it, then you can look at the equations and see for yourself if they make mathematical sense (or not). Was Galileo's contention that the Earth orbits the Sun dogmatic? What about the assertion that the Sun orbits the Earth, was that dogmatic? What's the difference?

> it is through discussion with people we may disagree in which new ideas can breed
> and grow. this was my ultimate goal in talking with you.

This is all very nice, but did you bother to find out what my 'ultimate goal' in talking to you was? Or is it all about yours?

Some-but-not-all people get upset when you point out how their beliefs do not correspond to the facts. Socrates was sentenced to commit suicide and Galileo died under house arrest.

I won't say whether or not this is true, or applies in this instance.

> every system has its flaws. both positive and negative. and no system is a rigid
> single dimension but rather varying layers of slight differences. this includes every
> political and economic system thought of or just living in the realm of dreams.

This, in itself is a dogmatic statement.

Look, man. I like you. I appreciate your comments, your earnestness, and willingness to engage our discourse. I also appreciate your respect and appreciation (although I can't say I'm sure how I've earned or deserved it). You've apologized for what seems to me to be ad hominem and I appreciate and accept your apology. I, too, apologize if you seem that I've been terse or avoidant in authentic engagement in dialogue with you. But in keeping with the points and arguments themselves, I think we'll both be much better off in terms of learning and growing and avoiding going off-track or off-topic into commentary about the messenger as opposed to the message.

Going to the Doctor in America

Bruti79 says...

Neuroscience and biochemistry yes. =)

You may not like it, or find it romantic, but it's something we can see and observe.

What evidence do you have to present?

As for science as a religion? Nah, it doesn't work like that. Science is a series of conclusions based on observations (very watered down term.) If things happen that change our observations, we change our conclusions. When is the last time something religious or spiritual changed how they think. It happens a lot in science. In a counter point, it took the vatican about 400 years to apologize to Galileo. =)

I'm not saying it can't happen. I'm saying there is no evidence to support what you're saying. Because there are processes in the brain that we can see and observe and form opinion off of.

If you have a way or process that can show some fact/proof/observations off of spirituality, I'd love to see them. It's the same thing with ghost hunters, in the history of the world and people, the answer to anything has never been ghosts. =)

enoch said:

@Bruti79
right on.
thanks for replying.

neuroscience is your answer in regards to consciousness eh?
how...unsatisfying.
the answer is no answer at all man.

let me try for you:
we dont know.
BUT we are making great strides in neuro transmitters and neuroscience and microbiology that it is possible that one day we WILL know.
but as of today?
we dont know,and what we dont know is a LOT.

see? better.

and your response concerning love!
breath-taking!
"We fall in love, or hate, or feel "meh" about something because of the stuff in our brain that makes our personalities"


i know better than to try to get you guys to listen to my fluffernutter philosophies.
you guys are all about your religion..i mean science..yes.science!

it is all pretty exciting to me as well.
thanks man.stay awesome.

Bill Nye: Creationism Is Just Wrong!

shuac says...

Well, don't forget about peer review. That's the crucial thing that sets science apart from religion. No hypothesis becomes a theory until it's been road tested like a motherfucker. Since religion relies on "revealed wisdom," it can't possibly hope to keep up.

For instance, did you know that Galileo might have been wronged back in 1632 when he was ordered to stand trial in Rome for heresy?...and that this was revealed to the Pope...in 1992??

That's correct, it took 360 years for the Vatican to admit that the earth is not the center of the cosmos. Granted, there wasn't a lot of peer review happening in 1632...but it did happen eventually. More importantly, it happened in spite of religion, not because of it.

So with religion's impressive track record of getting it wrong, and more impressive foot-dragging, why should they be the authority about the age of the cosmos? Or condom use? Or homosexuality? They have proven themselves quite unable to do so.

Science is the one with the winning track record, fuckers.

You'd think that if shinyblurry was correct that scientists would agree with him. Scientists aren't trying to "prove" anything -- they want an orderly universe just as much as shiny does. What do they gain from insisting on the universe being older? Shiny and his ilk have an agenda -- scientists don't.

They have been known to be blinded by their egos, but that doesn't last that long. (Lots of new discoveries and theories have been poo-poo'd before they become accepted wisdom. Because the data is more important. Ego doesn't win in the long run.)

If a scientist could prove the existence of god, a scientist would.

Plenty of scientists do see the hand of god in the orderliness of the data, the elegance of the math, the clockwork of the mechanisms of the universe. They just don't insist on it for everyone.
