Why am I bisexual? Why do I want to penetrate the anuses of young Asian and white men under the age of 20? This is clearly not an evolutionary advantage. If I could take a pill and make it stop forever I would, because I am so fucking tempted to pin a teenage boy down and destroy his ass, possibly giving me HIV if the condom breaks. I have never found a satisfactory answer on google. No one is looking for SNPs because it's not "PC."

I hate existing.

Yes. Every goal I make I fail. I move from failure to failure, aging and getting fatter.

Planetary orbits, electron orbits, moon orbits, sattelite orbits, etc.

If gravity attracts two object following G*m1*m2/R^2 and Coulomb force attract following k*q1*q2/d^2 shouldn't everything planets collapse into the sun, every moon satellite collapse into their respective planets and every electron collapse into the proton/neutron nucleus??

>shouldn't everything planets collapse into the sun
No, because centripetal forces are balanced against gravity.

>every electron collapse into the proton/neutron nucleus??
This is a bit more complicated. Classically it was understood as the same idea as above. However the more modern understanding is that the electron has no definite position until it's measured. On measurement the distribution of possible positions collapses to a single, definite position. The most likely position is the Bohr radius, while the average position is 3a/2, where a is the Bohr radius. Now given the nucleus has a finite size, there is a small but non-zero probability of finding the electron within the radius of the nucleus, ie. theres a small probability of finding the electron is inside the nucleus.
>>
Keep in mind that a dipoles attraction is proportional to 1/r3
>>
It's a matter of gravity vs. centripetal force. You're right to some extent in that '''eventually''' everything orbiting any given object will, if uninterrupted, fall into the gravitational center, but centripetal force holds it out for a while, and the result is orbit.

I used to think vaccines, preservatives (all), and a whole bunch of other okay stuff that uneducated people just love to spew out incorrect facts on. But, GMO's still bother me, mostly because of the spreading of genes to other plants that aren't supposed to have them. I don't know /sci/, can you help me of my phobia?

gmos are bad. not in principle but do to the ecological consequences of the agricultural practice genetic modification is used to support.
the "gmo causes cancer" issue is a starwman problem that the agrochem "public realations" industry directs attention to in order to distract from the issues that people should rationally concerned about
th people saying that GMOs are fine have been bamboozled and are acting smug about it
>>
There's no reason to be bothered with GMO's.
Current GMO strategies are based on inserting a piece of DNA into the crop, which then either lets the crop produce a protein or compound (via injection of synthesis pahtway) or it destroys a certain gene.
Look up bt cotton for example: https://en.wikipedia.org/wiki/Bt_cotton

There is no evidence that suggests GMO's are harmful, but caution does need to be taken of course.
There are classical crop breeding programs which try to make better varieties of crops through classical hybridizing, but this is just too slow (20 years). Compared to a genetically manipulated variety (which can be made in ~5 years and has profound effects on yield almost always), there's just no comparison.

How would you go about detecting methanol in ethanol with only limited equipment?

I'm in the developing world and methanol contamination in the local rice whiskeys is a big issue, and unfortunately sub-standard pre-packaged alcohol is being imported from developed countries

re-distilling is a logistical issue, as it would require re-bottling and locals don't have the facilities for this
and batches are generally small, making mass-re-distilling unfeesable

I also doubt I can get access to sodium dichromate, in fact "chemical" and "pure" don't belong in the same sentence out here

normally I would smell the contamination immediately, bu the local whiskey is foul to begin with and goji berry is often added as a flavoring which (coincidence, coincidence) has a very similar after-taste to methanol

>>
Couldnt you just heat the whisky until it reaches methanol's boiling point, and measure how much mass is lost ?
>>
>>8961650
I considered re-distilling early on, but the issue would be as follows

A. it would require opening every individual bottle of spirit, and since re-bottling isn't available it wouldn't be sustainable or financially viable
B. batches are small, often from a single household, to effectively re-distil the spirit I would have to blend a number of batches together to complete this process en-masse.
The villagers trade moonshine on reputation, sellers with more valuable moonshine wouldn't participate as it would effectively create a base price
C. I can get access to accurate thermometers, but fuel here is on the form of charcoal so reaching the precise kind of temperatures required would probably result in waste
D. because of low accuracy I would have to distil a large sample

Alright /sci/, let's talk about Anxiety Disorder! What's the best treatment? Do you have it? Are you sedentary?

I was on meds for 1 year, felt confident enough to drop it, and after 6 months I'm feeling it's coming back. What should I do? Maybe take meds for the rest of my life?
30 posts and 1 images submitted.
>>
Work out.
Eat healthy.
Fixed sleep pattern.
When anxiety attack comes up, find a mechanism that works for you (without meds) that makes you calm the fuck down ASAP. I use a meditative pose and breathe in/out very controlled and slowly and I've basically gotten over them and can control them whenever they come up now.

Also: critically evaluate your own life, do some introspection. Could there be a reason you have anxiety? Addressing that problem and working towards facing your fears or getting rid of that situation might be extremely beneficial.

You need an active lifestyle that you will continually have to brush up on (you'll never be done with working on yourself), but it's a hell of a lot better than to feel like you're getting crushed by your own thought of impending doom

Not true according to my personal experience because all the people that are good in math that I know dont play a single instrument and all the dumb fucks that cant even do 7th grade algebra play a lot of instruments or are in a band, sing etc. It helps if you are good though because I learned the guitar pretty easy when I was 7 but dropped it after 2 years because I didnt like it.

Strangely it is quite common that people with a medical degree often are musicians.

You might want to look up the inverted omega, pic. related.
>>
>>8959106
Dunno about that but you might find a correlation there since I am pretty sure raising kids to play music is a parenting technique that makes kids smarter. It teaches nuance and patience and focus and shit. So I wouldn't be surprised if a lot of people in smart fields know how to play.

PhD is not a meme if you want to do research in academia or tech industry. For any non-research positions it's completely unneeded and you'd be better off getting work experience instead of being a source of cheap labor for professors.

>Thoughts on the Paris accord
>Keep discussion /sci/ related
This is inherently a /pol/-type question. My general thoughts are this:

>Climate change probably exists
>Climate change is probably caused by humans
>Anyone bringing up "muh 97%" is doing more harm than good because this suppresses differing opinions, which is the antithesis of science. People in general are more concerned about fitting in than they are about the truth, so this makes people who might otherwise dissent keep their mouths shut.
>Given that the Paris Accord is non-binding for everyone involved, it's utterly pointless and retarded. We'd just end up keeping our end, and "developing nations" breaking theirs. But hey, at least they got billions of dollars of taxpayer money!! Pretending to do something to feel good isn't the same as doing something.
