http://www.esa.int/Our_Activities/Space_Science/Gaia/Gaia_s_billion-star_map_hints_at_treasures_to_come >On its way to assembling the most detailed 3D map ever made of our Milky Way galaxy, Gaia has pinned down the precise position on the sky and the brightness of 1142 million stars. What does /sci/ think of Gaia's new galactic map? Significant astronomical achievement? I think it's beautiful to look at if nothing else.

Hello /sci/, I have a confession to make. I am really disappointed about my intelligence. I am a double grad student (computer science and math) who wants so much to be someone out of the curve. At first I was self aware of my limitations and went ok with being average, until I decided I wanted to be a college professor. Then I changed my whole mindset, started up on math course, started studying to git gud and step out of average zone. The problem is that I'm 9 months into this and already demotivated. I have been getting average grades (even though I noticed a step up from my old performance) and so have colleagues whom don't study half of what I do. On top of that, there are colleagues of mine who doesn't even take notes during classes and score good grades consistently. How will I ever get to be a great researcher/teacher when there are competitors who are much better than I. I already attempted to mimic their way of learning (taking no notes and focusing on class solely) but it just doesn't work for me. I forget details in a matter of weeks. Help me guys. What do you guys do to be excelent? I want to be recognized. I know there are quite a few of other doublegrads out here, so give me your view, how do you cope with the giant amount of classes and information every day? Thank you in advance.

Intelligent life is probably so rare in the cosmos and requires so many accidents stacked on top of each other for it to evolve that the nearest intelligent aliens are outside the observable universe. Right?

Celestial determinants of success in research

>Using the ????2 test, we found a general association between zodiac sign and the likelihood of having received the Nobel Prize in Medicine and Physiology (p = 0.042). In particular, the odds of having won a Nobel Prize were increased for people born under the sign of Gemini (odds ratio [OR] 1.90, 95% confidence interval [CI] 1.12–3.24, p = 0.017). Conversely, the odds of having won a Nobel Prize were decreased for those born under Leo (OR 0.35, 95% CI 0.16–0.82, p = 0.011). So what is your Zodiac sign /sci/?

A proof for infinite sets that contain more elements than others?

4 more posts in this thread. [Missing image file: ]
So, /sci/, I want you guys to consider this. 1. There exists sets X and Y 2. There exists a number x, x is an element of X{R|1<x<2} 4. There exists a number y, y is an element of Y and is an element of {R|1<=y<=2} 5. X is a subset of Y 6. ?X implies Y AND x implies y 7. ? 1 and 2X,1 and 2 Y 8. 1 and 2 are NOT an element of X, and ARE an element of Y AND 1 and 2 are elements of Z 10. Set Y contains exactly two more elements than set X. 11. ?Y>X What do you think, /sci/? Is it proof of different levels of infinity, or that infinity plus two is not infinity? Am I retarded? Could my proof be revised? Am I doing something wrong? I talked about this with my calculus prof. Also, how do I do this using the LaTeX? If anyone could do that, that'd be nice. But, my reasoning in plain words: >Think of two sets >In the first set, are all real numbers greater than 1, less than 2. >In the second, are all real numbers from 1 to two. >The second set has every element that A has. >The second set has two more elements, 1 and 2. >Therefore the second set has more elements.

Evolution Just Got Harder to Defend

How can Darwinists still defend the theory of evolution? There is mounting evidence in the fossil record that it is bunk. >A new fossil discovery makes it even tougher for Darwinists to explain the origin of life. >There’s an old story about a chemist, a physicist, and an economist stranded on a desert island with nothing to eat but a can of soup. Puzzling over how to open the can, the chemist says, “Let’s heat the can until it swells and bursts from the buildup of gases.” “No, no,” says the physicist, “let’s throw it off that cliff with just enough kinetic energy to split it open on the rocks below.” The economist, after thinking a moment says, “Assume a can opener.” >There’s more than one trade that deals in assumptions. The way Darwinists approach the origin of life is a lot like that economist’s idea for opening the can. The Darwinian mechanism of mutation and natural selection explains everything about life, we’re told—except how it began. “Assume a self-replicating cell containing information in the form of genetic code,” Darwinists are forced to say. Well, fine. But where did that little miracle come from? >A new discovery makes explaining even that first cell tougher still. Fossils unearthed by Australian scientists in Greenland may be the oldest traces of life ever discovered. A team from the University of Wollongong recently published their findings in the journal “Nature,” describing a series of structures called “stromatolites” that emerged from receding ice. http://cnsnews.com/commentary/eric-metaxas/evolution-just-got-harder-defend

Psychiatry, psychology, and other mental health care-related fields

153 more posts in this thread. [Missing image file: ]
What do you guys think about psychiatry, psychology, and other mental health care-related fields? I ask because, so far, I've been diagnosed by both a psychologist and psychiatrist as having four different disorders: Major Depressive Disorder, Generalized Anxiety Disorder, Social Anxiety Disorder, and Attention Deficit Hyperactivity Disorder. However, I can't help but notice that most people don't consider these to be real "illnesses" and that these things are entirely "in your head" and that you can easily "will yourself out of" these problems. In fact, even I'm not sure that I believe these to be real illnesses. Nobody in my family (or anybody else, for that matter) seems to give a single fuck about me having been diagnosed with these disorders. A cousin of mine simply scoffed at the idea of me being diagnosed with ADHD, making a dismissive gesture and proclaiming "everybody has ADHD!" My mother tells me that I need neither medication nor psychotherapy, that I should use my own will power to stop having depression. Other people tell me that social anxiety isn't a "real problem". I've taken antidepressants and anti-anxiety medication in the past, and they only increased my misery tenfold. Meanwhile, my psychiatrist wants to stop prescribing me Adderall (which I've been taking for nearly two years) because it might hasten the onset of schizophrenia. Mind you, as far as I know, nobody in my family has been formally diagnosed with schizophrenia. And the only reason my psychiatrist is concerned about this because I told one of the nurse practitioners who works at this same practice that I wanted to be referred to a geneticist to have myself tested for any possibly genetically inheritable disorders and/or diseases (such as: Alzheimer's disease, schizophrenia, antisocial personality disorder, etc.) And my psychiatrist wants to prescribe me Abilify instead. So do you guys think that psychiatry, psychology, and/or other mental health care-related fields are bullshit?
