All Time 10s: Common Science Myths

Raveni says...

>> ^GeeSussFreeK:

The glass myth is actually incorrect. I used to have this misconception, but glass is quite sturdy, with viscosity greater that many metals that are considered solids (depending on the glass of course).


Tl;dr: "If the windows found in early Colonial American homes were thicker at the bottom than the top because of "flow" then the glass found in Egyptian Tombs should be a puddle."

Misconceptions About Temperature

...Makes me curious to experiment... If you put steak on one and leave the other in the packet both at room temp... How much faster is the defrost time? 100%? more? is there a known ratio for these things?>> ^Sagemind:
Also, I have a defrost board in my kitchen.
It's the same as a cutting board except it's made of aluminum and it has feet to maximize the heat transference.
It increases the defrost time of things like frozen meats and also affects the cooling times of things like a hot bowl of soup or something that comes out of the oven.
When you place something frozen on it, it practically freezes itself. The feet exposes the underside to the open air so it can expel the cold quicker. If it was flat on the counter, the whole thing would ice over.



It is REALLY fast, we used to have a store bought product like this, just a glorified piece of aluminum. Your talking at least a third of the time if you can get good contact, rounder objects like turkeys are a bit harder. But for steaks and hamburger, it was less than 10-20 mins straight out of the freezer, and lots easier than having to cycle out water for half an hour or so in the sink. Miracle Thaw is what I believe it was called, but you could achive similar results with just a normal ol pan...though, they aren't flat so it might not be as optimal. You could go grab yourself a bunch of old computer heat sinks with copper and blow the aluminum ones out of the water!

Why didn't i ever think of taking meat out of it's packet and putting it on a metal tray to defrost before now?


The kitchen sink works well for that but most people leave their meat in the styrene tray which is a pretty good insulator. ; )

Incidentally, alumium is the first pronunciation, but was later changed to aluminum, then aluminium by the guy who discovered it.

http://www.worldwidewords.org/articles/aluminium.htm

Internationally, aluminium is the accepted spelling but aluminum is still strongly used in the US. Both are essentially correct as it's fairly common knowledge that they are the same thing, but it serves to be a bone of contention of course. ; )

Thank you for your response, it has made your initial comment much clearer. What you need to understand about the video and why my response was so harsh is that the song, while being directly inspired by Akin's comment, is not only about him, but about society's distrust and often denigration of women when it comes to sexual abuse. While you may have a point about Akin (I doubt it), his "slip-up" does not come from out of the blue, but stems from a sadly widespread misconception of sexual abuse, mostly held by religious conservatives who tend to blame the (female) victim, for being "lose", "asking for it", etc etc (when it pertains to homosexual rape/abuse they chalk it up as part of homosexuality's evils; viz the response to abuse in the RCC).

The reason your comment elicited such a drastic, gut-born response is that it echoes every misogynistic table-turning that crops up when sexual abuse of women is being discussed, i.e. the accusation of "man-hating", "fear-mongering" feminazis (as well as the whole "men get raped too!" trope, which no one is denying). Rare are the feminists who hate men (and those who do are wrong to do so, and generally called out for it); what we hate is patriarchy and everything it entails. The tactic of misrepresenting feminist arguments seemed to me what your sarcastic comment was about, hence my reaction.

So the strawman I copiously insulted was the MRA-hole whose misogynistic intent I read into your comment, and to be quite honest, it was (and still is) very hard to read anything else into it. But you have my apologies for insulting you if that was not what the comment was about. And since you and I are not alone in this exchange, I propose posting our discussion on the thread in question, that way people can see what you meant by your comment and see why I reacted how I did. What think you?
In reply to this comment by Kreegath:
Where your guessing I'm white comes from, or how my skin color or gender would matter in the least, I don't know. You clearly seem to have some kind of history with MRA people and believe them all to be misogynists, and perhaps they might all be. I don't know, I'm not affiliated with them. But you equating my criticism of the video with being in cahoots with MRA convinced you I had to be pushing some agenda and blinded you not only to the intent of the sarcasm tag but also to any other possible meaning of the post, instead reading a simplistic turning-of-the-tables jab into what you seem to have perceived to be my sexist manifesto. That's the problem with reading a sarcastic post seriously and afterwards taking the sarcasm tag as disingenuous.
What I found objectionable with this video was that the artist misconstrued Todd Akin's incredibly stupid attempt at connecting pregnancy due to rape with his pro-life stance to say so much more than he did, that he considers any of those in lyrics mentioned scenarios of rape to be illegitimate. He didn't say that, though, so with all the things that he could be criticized for, there's no need for the artist to manufacture an outrage that he actually didn't put into words. Maybe you know something about him and his stances on rape that wasn't widely brought up in public during all this, but I only read his public statement linked in the description bar as well as reading about him on wiki and didn't see anything in it even hinting at him thinking all rape is illegitimate. So, what I did was basically the same thing I disliked about the sifted video, taking one aspect of the song that I reacted to; all mentioning of gender as pertaining to rape like: him taking her out, husband's privilege, he didn't have consent, short skirts. As such it's misrepresenting the artist's intended message (as I understand it), that Todd Akin thinks women can't be legitimately raped, to instead say that she thinks only men rape only women, hence the sarcasm tag. It's very easy to put words into other people's mouths.

It's really easy to jump on someone who's already being jumped on, and that is what I thought this video did. I didn't think it brought anything to any discussion, I didn't think it was funny and I thought it was unfunny because I perceived it (and still do, since nobody has divulged any further information) as hate fuel and character attacks based on misrepresentation. This isn't the first time I've reacted to this, as you can see me defending another borderline reprehensible person from what I though was unjust and unwarranted avenue of criticism: http://videosift.com/video/Bill-OReilly-amazed-that-Black-res
taurant-is-civilized

You are free to challenge any post all you like, but telling me to go fuck myself, that I disgust you and that I'm sexist and somehow pushing some misogynistic agenda, which has no basis in anything in the post, is not challenging anything. That's antagonism at best, slander at worst. You don't know anything about me, neither how I act, how I have acted nor how I think and feel, so making all kinds of value judgments on my character and verbally abuse me is completely unwarranted. I didn't discriminate against women in that post, I didn't imply women were less than men, nor do I think that. Both actions and words have consequences, even in internet communities, and any and all rash language and inflammatory rhetoric will still linger on long afterwards.

In reply to this comment by hpqp:
I will concede this much: my response was emotionally laden and insulting. But attacking what very clearer appears to be MRA misogynistic BS is not "white knighting", despite my perhaps overly heavy-handed manner. Or does one have to follow specific guidelines in order for their challenge of your comment's apparent ideas to be taken seriously? If you had a valid point to make with that comment, I think it's fair to say you failed miserably at getting it across. So instead of accusing me of "comment noise" because you don't like what I say, why don't you come and clarify what you meant? It's unfair and rather shameful of you to call my response petty and wildly assuming; your comment does not allow many other interpretations than the one I made. The only mere assumptions I made were to your gender and ethnicity, based on the fact that the MRA movement is almost entirely the resort of white males.

Come back to the thread and provide in clear language what you meant by your sarcastic lyrics, and if I was wrong in my interpretation thereof I will be quick to apologise publicly for getting you wrong.

(I am taking this off "private" setting because as a continuation of an open sift discussion I believe it should be available to anyone involved. I stand by my words, and I am sure you do to.)
In reply to this comment by Kreegath:
Look, I don't know what emotional baggage you're carrying or what possesses you to go so overboard with white knighting, but you're behaving childishly and if you can't talk to someone you disagree with, or you think you disagree with, without starting to infer your preconceived notions onto them and insult and cuss them out, you are no better than any of the other comment noise that plagues youtube. If you want to rise above such pettyness, apologize for drawing wild conclusions, insulting and accusing me on the basis of those wild conclusions and maybe we can have a discussion about what my post was actually saying about that person's video.

How do you know if you're suffering from man hating and fear? ♫
I'll tell you how to spot, man hating and fear ♪
You're not sure you've got, man hating and fear ♬
Well here's a little lesson for you,
Tell me if the following things are true:
I think all rapists are men - man hating and fear
I think all victims are women - man hating and fear
I rub out all grey areas to prove a moot point - man hating and fear
Men should have no rights to defense against allegations of rape - man hating and fear ♬


Oh, looks like we've got an MRA-hole in the house. Let me guess: you're a white male with malignant priviligitis, amirite? Did any one line of the song suggest falsely accusing someone of rape? Or calling all men rapists? Or hating men?? Oh wait, you ticked the sarcasm tag, that makes it all an a-okay bit of humour right? Wrong.

Your kind disgusts me. And by that I don't mean "men"; no, real men (and women, and anyone in between) know to respect another person's consent and their choice to retract it at any given moment. No, by "your kind" I mean the slimy, any-one-who-points-out-the-sexism-in-our-society-is-a-man-hating-feminazi-and-fear-mongerer kind.

I won't stoop to the MRA-low of wishing rape on you, because I would not wish it on anyone. Instead, I'll kindly suggest you go fuck yourself, because anyone in their right mind, male female or otherwise, would not consent to it with you if they knew your sexist stance. /angry rant

*quality song btw




The Truth about Atheism

shinyblurry says...

This is a very ugly misconception that you seem to have. Except for several very vocal celebrities, Atheists aren't "against" religion... there certainly isn't some central creed or governing body telling us what to organize against.

What Atheists are against, in the western world, is having our government (and hence our lives) tainted by beliefs that we don't hold. In Muslim countries, there are harsh penalties (up to Death) for blasphemy... so you won't find many people speaking up. In the US, Muslims and Hindus aren't making laws to persecute us, hence why you don't hear us complaining about them.

There's no crusade to remove Religion... There's no attempt to persecute Christians, we just want the ability to go about our heathen lives in peace.


Here is a bunch of atheists who disagree with you: http://www.reddit.com/r/atheism

This is probably because the content in the video was a pseudo-intellectual, pseudo-philosophical sermon that made such astronomical leaps that it didn't need to be said.

Pretty harsh point for the people who enjoyed it. If that's true then make your case against it, since you have understood it so well as to completely dismiss it.

There wasn't an argument made for this. For some reason, you seem to believe that "the things we do in life have no meaning after we die" turns people into sociopaths... And since we're not all sociopaths, that proves that God exists. The first issue is that you assume that 'meaninglessness' leads to sociopathic behavior. Secondly, this is a textbook example of Denying the Antecedant fallacy.

Show me where anyone said this, or even implied it.

--Skipping the story--

Is this really your argument? 80% of the people you meet were raised Christian (even most of the Atheists)... This is confirmation bias... You can't say something is put there by God when Religion was preaching to them on a weekly basis. If there really were some sort of imperative planted by God... wouldn't there be far less religious wars?

Breaking news... people really do spend their entire lives 'waxing philosophically'... People do die for things that their religion has told them was wrong, but they felt was right (Anti-Gay Violence?).


That's what is called sitting in Gods lap to slap His face, or borrowing from my worldview to establish yours, and this really isn't an argument in your favor. Also, as far as sin goes, do you understand Christian theology?

This is news to me... I believe Mormons teach this, but all other denominations preach that when you accept the Holy Spirit, it moves you to do good deeds... that the good deeds aren't your own.

Revelation 22:12

And, behold, I come quickly; and my reward is with me, to give every man according as his work shall be.

You seem to be deliberately misunderstanding me here. I was very specifically using the definition of 'meaningless' that the speaker above uses... as in, 'meaning nothing after you die'.

But that isn't the definition he used. He applied it to past present and future.

My point exactly. The only thing that matters is that you've accepted Jesus as your Savior. NOTHING else matters... hence it is meaningless.

Where do you get the hence from? Meaning is meaning. Even if there was only one meaningful act you could ever do, it would still be meaningful. However, in the context of God, everything takes on its true meaning, attaining the purpose it was created for.

You completely ignored my point here. Except for the Mennonites, there are no other denominations (in the US) that take a hard stance against violence. None. Zero. This country is 80% Christian, and yet we've been at war for 209 of 235 years of our existence.

No ignored my point that religions don't matter, because the true church is the body of Christ. You want to blame an institution, and that's fine, but that isn't what the church is.

Let me be very clear on this: ALL CHRISTIAN RELIGIONS IN THE US ARE FALSE purely based on this one single fact (again, excluding Mennonites)... Granted, that doesn't prove that God doesn't exist... but it certainly does mean that I can't trust any US-based Christians...

I believe all denominations are false because they bring separation to the body of Christ.

What have you done to end discrimination (of ALL types)? Have you participated in any protests against wars, for Gay Marriage, for Women's Rights? Have you stood up in Church to let everyone know that you think it's wrong to discriminate against others, regardless of what they've done?

I'm against discrimination, flat out, and I would say something if I see it. I don't go to protests, no. I use my time to help people in many other ways.

I'd recommend reading up on philosophy, logical debate, and comparative religion... and finding a denomination that is above reproach. The reason Atheists always seem to have the same 'tired' arguments all the time is because we don't need to have new ones... the old arguments still come out in our favor.

I'd recommend the same to you, and the old arguments obviously are not coming out in your favor since atheism is in decline

http://www.sneps.net/RD/uploads/1-Shall%20the%20Religious%20Inherit%20the%20Earth.pdf

This is the point where most Atheists become seriously pissed... Simply stating that someone is wrong because they don't believe what you believe is not the way to have a discussion. Especially when what you believe isn't widely believed by your own fellow Christians. LCMS, Presbyterians and Seventh-Day Adventists are the only denominations that officially preach Young-Earth Creationism...

The whole point is, if it is an old earth, it doesn't make sense that Jesus would come after 198000 years of struggle. That doesn't really prove anything, but the entire point is invalidated if it is a young Earth. Do you see what I am saying? I didn't say he was wrong, I just said what I believe.
