So it seems about,28 countries in the world have banned GM products, mostly in EU. Can someone tell me the rational? http://sustainablepulse.com/2015/10/22/gm-crops-now-banned-in-36-countries-worldwide-sustainable-pulse-research/#.WBKUmvorI2w
From my knowledge of molecular biology and genetics, it seems the problem that people have with GMO is the idea of inserting advantageous genes (DNA sequences) from other species into plants. It is especially off putting to them because these genes are from bacteria. Is this not an over reaction considering all organisms share... Comment too long. Click here to view the full text.
I feel gmo's are totally fine and it's just the media hyping shit up like they always do. This is probably the only way we can continue to feed people in the future. I see where the concerns are but think about all the chicken the world eats. There is literally no way we can continue to keep up without them. But I'm probably just talking out of my ass because I just know basic bio stuff.
>>8441684 naw it's just a propaganda artice claiming that old urban legend the Chinese food places serve dog to American customers. I'm sure some Chinese in the U.S follow their tradition and eat dog but I doubt they are serving it instead of chicken or pork lol.
What does pic related mean? I understand that I need to find the angle where the vectors are either coming from or going to B but how and why do you know to write A->B instead of B->A or B->C instead of C->B.
Looked in the markscheme and it came up with B->A and B->C
Does Newton's Laws of Motion prove or disprove the official story of 9/11?
First law: In an inertial reference frame, an object either remains at rest or continues to move at a constant velocity, unless acted upon by a net force.
Second law: In an inertial reference frame, the sum of the forces (F) on an object is equal to the mass (m) of that object multiplied by the acceleration (a) of the object: F = ma.
Third law: When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction... Comment too long. Click here to view the full text.
>>8435851 Well considering the height of the impact zone where the damage would of occurred, I have trouble seeing how the top section of roughly 15-20 floors could give in and proceed to plummet through 70-80 floors. it is especially concerning when you consider the support systems, designed to with stand three times the weight of the tower were destroyed in this floor-based collapse. Isn't the section of building several floors below impact zone considered healthy and undamaged structure? How did its support for the weight... Comment too long. Click here to view the full text.
Some of them work at my company but I've never had any direct contact with any of them, however from what I've seen, it seems that they're literally not doing anything -- ever. Yet they seem like the smuggest motherfuckers ever with this condescending attitude -- they will look at everyone else like they're beneath their level for some reason.
What's the point of them? They aren't programmers, they aren't system engineers, when my friend told one of them that they're only gathering... Comment too long. Click here to view the full text.
>>8445960 As your article suggests, "data science" is basically the business buzzword of the decade, so depending on your company you may find "data scientists" working on everything from data acquisition to data preprocessing, data warehousing, data cleaning, data analysis, data visualization, forecasting and even data-driven (i.e. evidence-based) policy recommendation. Don't expect HR to know the difference.

All scientists and enlightened humans must squat to shit.
Scientifically studied the benefits are: - Less time to shit - Cleaner shits with less required TP - Healthier for you and avoids many negative health effects of the strain
Both the time needed for sensation of satisfactory bowel emptying and the degree of subjectively assessed straining in the squatting position were reduced sharply in all volunteers compared with both sitting positions (P < 0.0001). In conclusion, the present study confirmed that sensation of satisfactory bowel emptying in... Comment too long. Click here to view the full text.
Good thread last time, let's get some more serious discussion!
A few prompts: >any cool theorems you have read lately? >any reference requests? >looking for anyone to study online with? >any other prompts?
Pic related is a theorem I find fascinating. For those unfamiliar with it, it is a basic result from Morse theory. Essentially given a nice enough differentiable function on a manifold M, you can determine it's shape up... Comment too long. Click here to view the full text.
>>8437059 Interestingly, I have read about Milnor's proof of the existence of exotic 7-spheres last week and he used this very fact in order to prove that some weird fiber bundles he had constructed were in fact topologically spheres. Pretty nifty
>>8446296 IMO the best thing to do is to work as many problems as you can. Many textbooks are crap; get Zumdahl's 'Chemical Principles' You can find the textbook and solution's manuals here: http://bookzz.org/s/?q=zumdahl+chemical+principles&yearFrom=&yearTo=&language=&extension=&t=0
>>8445825 I had it for my entire life, but then I conked my head a few months ago and it sort of increased, and I now also have those sparkles when I look at the sky and other little starbursts/afterimages/trails of light etc.. So, I guess we're in the same boat.

Ive spoken with therapists as well, they told me they saw shit when they did neck exercises. So there is chance that it has something to do with blood flow into my brain.
>>8445844 yeah, I get these mild headaches now, and a lot of the time, I feel it in my neck. really weird. the lingual gyrus is in the back of our brains by our necks, the red part of this image. who knows what's really going on. I've noticed very mild difficulties with recalling words and actually speaking, too, apparently some people with VS also experience that, and the lingual gyrus has to do with recognizing words/letters, shit like that I suppose. It has nothing to do with your intelligence though, and I DO feel... Comment too long. Click here to view the full text.
I know it's unlikely that i'll ever amount to much, but whenever i find myself wasting time on the internet i think about the useful skills i could be learning and get depressed, i seem to have a sliver of hope left in me.
I'm so confused can someone help me with this? The first molecule is the starting molecule and the molecule underneath is what you should get as an answer for the hydrolysis reaction. I don't really understand why it shouldn't be the second picture I posted?
Hey /sci/, undergrad baby here. I'm currently in my sophomore year doing a double major in math and cs. I was reading Hardy's "A Mathematician's Apology" yesterday, and I was wondering what you guys think of it.
Personally I think there's some truth to freshness, spontaneity, and power of youth, but like most things in life, the lack thereof doesn't wholly determine what you can and cannot do. That could just be my naivety and wishful thinking, though.
>>8444936 >That could just be my naivety and wishful thinking, though.
If you're not wired for higher math by your early 20s, it's really hard to overcome. There are some cognitive skills that don't peak until later in life, but sheer mathematical aptitude peaks for most people in their late teens.
>>8444936 Hardy's quote is pretty stupid. It's mostly not true and as far as it is true it applies to literally everything, not just mathematics.
Look at any field of society at all. How often do the paradigm-shifting ideas come from some old codger? It's not as though a switch flips and all your mathematical talent disappears past 60, it's that generally speaking old people like things as they were and don't want to flip the world on it's head.

I read somewhere that Bill Gates' roommate stated that Bill studied almost non-stop for thirty-six plus hours, then he would sleep for ten hours, woke up to eat real quick, and then he would study for another thirty-six plus hours.
How does one do this? Was Bill on crack??
Does anyone know if it's even effective to study after a certain amount of hours? Isn't there a magic number of study hours in which the brain stops retaining a fair bit of knowledge?
Usually I study for a normal period of time but whenever I have a breakthrough, a great idea, I'll get consumed by it and go at it for so long that I can no longer tell whether it's day or night. I just keep going back and forth from working to eating until I collapse.
>>8444803 The waves he is talking about are material waves not em. It happens because the photon you're sending to the car exchanges momentum with it, however at these levels, given your macroscopic measurement apparatus there'd be noticeable difference.
MD-PhD student here, on first year of my break. I was hoping to have a few less stressful years after the crazy amount of work I had to put to get here, so far my hopes haven't been panning out, but I'm just starting.
