Why is Chernobyl radioactive but not Hiroshima/Nagasaki?
>>8291800
If you look at a map, you'll see that Japan is close to the leading edge while Chernobyl is more to the middle. As the Earth rotates, the winds blow away the radiation over time. Since Japan is at the edge, it receives the most wind and loses its radioactivity the fastest. Chernobyl, being in the middle, receives much weaker wind that has been dissipated by the Himalayas.
This is why all nuclear facilities have fanners that run around the building with giant palm leaves, removing as much radiation as they can.

You tried

Chernobil exploded and got radiation in the atmosphere, Fukushima was just a meltdown - the fuel overheated and melted stuff, but it didn't cause an explosion.
Hi Sunflowers,
I will be graduating in the next yearin my compoutational biology major. So there is a lot I have learned about satatistics, machine learning (bioinformatics) and mathematical modeling (what they cal systems bio). But for a reason, I am thinking about studying medicine or pharmacy for another 6 to 7 years. I would be in my mid 30 when I am done, if I choose to study these.
The reason is, that I kind of feel useless with all the knowledge I have. Of course, if it were not for science (biology, chemistry, ...) we would not have all these advances in medicine and pharmacy, but the borader public is not realizing this. If you are not a doctor (medicine) the "normal" people dont even know what you are doing as a biologist (probably something with animal kingdom bla bla). So they dont even aknowledge, that this is some serious shit and we are on the frontline of human tackling the problems of the world (inlcuding bioeconomy, ecology etc.)
So I feel kind of useless...also, I think that, people are getting more and more stupid and laugh about educated people for their education. Look at turkey. They are all against research and academia...even being an educated person is dangerous right now.
Should have done medicine from the start...then people would say something like "ooohhhh he is a doctor". But most of these "doctors" would not know shit about how to treat people if t were not for biologists....
developed countries are also totally disrespecting scientists with their fucking time-limited contracts and shitty salary.
gonna kill myself with some anthrax...

Flee to a better country, return if things get improve.

Could you plz recommend one?
>>8291771
I feel the same OP.
How do people deal with that false feeling of inferiority to doctors?
So, There is this thing.
Imagine the possibility, that you can actually turn on the microphone and GSM resiever on your phone manually? Now think about that your phone is built only with 1 intention: un-spy-able.
How can this be done? Is there a way, we can make ourselves a phone, that we know exactly how it functions and what it is built out of?
I am not looking for /DIY/ part, I am looking for the /sci/ part. Anybody?
(I have in mind, that THEY know the GSM signal's location is known at any time the cell is on)
>>8291733
Define "spy-able".
Nothing will save you from a strong enough adversary.
>>8291733
So you want a cellphone that is free as in freedom?
Unfortunately, that is very difficult. The problem is with the baseband processors, they use a bunch of proprietary stuff and are essentially blackboxes.
IE the GSM receiver runs it own little operating system
>>8291985
>2013
>not using OpenGSM
It's fucking happening. The hippocampal prosthetic from Dr. Berger's group is becoming a real product now and undergoing clinical trials. This is a game changing technology because it means we can replace entire functions of the nervous system with prosthetics. Pic related.

wow that's really impressive.
I was going to post just how he's autistic and funny but that surprisingly seems to work.
Ehh? I thought we had no idea how memory works
What's the trick?
Hello /sci/,
A cute girl from my university asked us on a facebook group to solve this useless problem for her little sister in high school, but nobody could solve it for we finished calculus like 4 years ago.This is actually a good chance to talk to her and not look like a weirdo. You should know that many of my real-life friends got girlfriends, but I spent my life browsing /b/, so I hope you would be the cause to marry her and make those faggots jealous because she's an EE and actually the cutest girl in university better than their girlfriends.
>pic is related
>this is a true story, I'm not trying to make you solve my homework
>you shouldn't use l'hopital's rule or these shits
>>8291550
sin(0) = 0
so tan(sin(0)) = 0
also tan(0) = 0
the numerator is 0-0
The denominator can eat a dick, the whole thing is zero
Anon she's probably fucking one of your friends every day while you're doing her sister's tedious homework
What a cuck
biology majors of /sci/
did or is your university teaching you statistical analysis as part of your degree ?
if so, what programs are you using ?
>have met a number of american graduates who 'dont know' stats
>not trying to start a pissing contest
>just a confused anon
>>8291535
studying molecular biology, (bio)statistics is an elective, the other choice was biochemistry, I chose biochem, but I will be taking statistics soon probably, blabla
besides that they use maple ta and language-wise R (a bit at least)

The more we think, the faster brain cancers can grow.... That's really quite scary, we should revert to only feelings or instinctual behaviors and reserve thinking for things that really need to be thought about, and even then it might be better to start specifically designating those with very stable genes and lowest risk of cancer, to think for us, lest our own thoughts promote cancer. What do you think /sci/?
I think that pretending to be retarded constitutes being retarded.
A normal healthy person does not pretend to be retarded.
If you don't understand why, you should proceed with suicide.

Why?
You could have posted the link to the Stanford press release - and it would be somewhat less ridiculous.
>The findings were published online April 23 in Cell.
The link to the Cell paper, that's how you should have started the thread.
>>8291509
More energy usage=more cancer.
Literally one of the most basic laws of biology.
Nothing surprising here.
Lots of threads about who was 'best', but who was the shittiest scientist? Who fucked everything up the worst?
Surely some people have dun goofed.

CS.

Lysenko
We could probably add some recent outright frauds: Deepak Das and Marc Hauser.
Their impact was pretty limited.
Felisa Wolfe-Simon is another that comes to mind.
retractionwatch.com is very interesting

Do you know any good books on proving techniques (barring basics like Book of Proof)? I came across pic related in a footnote.
OP here. I know this one too, haven't read it though.
>>8291307
Basic techniques are all there are.
Direct
Induction (weak, strong, well ordering)
Contradiction
Contrapositive
Diagonalization
Proof by last lecture
>>8291413
This is not a book on proving techniques, but rather on the best proofs of all. Many of the proofs have some kind of "divine insight" that only applies in that one case and which makes them extremely elegant. As such, it's not really usable as a learning resource.
And being able to live in these virtual worlds that are indistinguishable from our own
>>8291259
you're living in it.
>>8291259
If we're simulating it to an atomic level then to store all this information the computer would need to be huge
>>8291270
Hmm, I have another idea then. What if it's not really down to the last atom but only appears so ad hoc, for example if a scientist were to observe an individual atom only then would it appear. Otherwise reality will only be at the resolution that conscious beings see. And perhaps if no conscious beings are observing something it wouldn't need to be simulated at that moment.
Doesn't Zenos dichotomy paradox basically proves that the universe is quantized?
>That which is in locomotion must arrive at the half-way stage before it arrives at the goal.– as recounted by Aristotle, Physics VI:9, 239b10
Because there has to be a point where distance can't be halved any more, to make sense of motion.
it could be that space is continuous but particles move in quantized leaps therefor bypassing the need to reach the half-way point
>>8291213
Or, you can cover an "infinite" number of intervals in a finite amount of time.
A good example of how something that is obviously false can be sold as truth by using the right language.
>implying simple word play proves that distances are quantized in our Universe
You're an idiot.
Can it run Crysis?
>>8291194
Only with the shaders on medium
>>8291197
boo
>>8291194
some guy was answering questions about quantum computers a couple months ago and said they could run games, but its no better than current hardware.
I have been a fairly heavy binge drinker for the past five or so years. How much have I fucked my brain and is there any chance of a full recovery? How much irreversible damage does alcohol do to the brain in general and what general methods are used to quantify it?
Day drinking?
I noticed that I became a better student and a more conscientious person when I started drinking
>>8291091
Alcohol poisoning usually reduces brain function immediately so you're pretty much out of luck bud
>>8291096
Not day drinking, just drinking like 8 to 15 drinks a night most nights for the past 5 years.
>>8291097
Alcohol poisoning seems like a pretty inexact terms. Like what specific levels of what metabolites does it take for it to be considered poisoning? Not disagreeing with you, just want input from a medfag or neuroscientist or something.
How would I prove this is linear /sci/?
Easy, just write down the formula you noob
>>8291045
What's the formula? I don't think I'll be covering this stuff in lecture until mid September so I don't really have any material on it, but all the stuff on differentiation for this first topic I've covered so I'm moving ahead
My book and khan academy doesn't give me shit
>>8291047
Bump for late night help? There's really no one else I can ask and I can't sleep right now... I-I love you /sci/...
