Dr Quantum - Double Slit Experiment Very weird shit I'll tell you... Almost like a creator or something.

or Uncertainty Principle, because almost everything in the universe seems to behave like both a particle and a wave at the same time.

Isn't circumcision culture in the U.S. incredibly strange? I find it so weird that almost no one ever mentions it or is open about their beliefs. Let's discuss circumcision in general. I'm curious about peoples' opinions.

Anybody ever create false memories while dreaming?

It's been occurring to me quite frequently lately.

I'm quite sure over half of the so-called "memories" I have tucked away never really happened. I'm also having trouble becoming fully conscious upon waking up because I believe what I dreamt really happened, putting me in a mood I wouldn't otherwise be in.

For example, I had a dream that I got into a pretty heated argument with a close coworker of mine. I woke up for school and never really thought much of my dream. I'm not even sure if I remembered it at that particular time. But at work, I'd feel myself giving a lot of resentment towards him. I even felt particularly annoyed by his presence until he asked me what was wrong. I thought about it for a while and I suddenly remembered the dream I had, and that it never really happened. When I told him he seemed really confused but we laughed and shrugged it off.

I had a dream about a black bracelet I had just bought. I liked it a lot. I woke up and like before didn't think much of it, or even remember it really. Then as I was getting dressed for school one morning I thought to myself "...you know what would look great with this jacket?" thinking of that bracelet. I was about halfway through eyeing up my entire room looking for it when I realized I didn't have such a thing.

This stuff is really starting to get to me. It's like these false memories play idly in the background of my head until something triggers them and I confront the fact that they never happened.

It's like half of the things I know and believe don't exist.

Why does this happen? Anybody else experience this kind of thing?
User avatar #4466 to #4458 - shadowhorn (04/24/2015) [-]
I too have experienced this. Really trippy and disorientating. Makes you question reality.
User avatar #4463 to #4458 - nimba (04/22/2015) [-]
Yeah I have a few false memories from when I was younger, pretty much everybody has some but won't ever realise it
User avatar #4459 to #4458 - wildberk ONLINE (04/21/2015) [-]
I experiance this WAY too often. I'm not certian why. But there are many times that I need to talk with people to make sure that I just didn't dream shit that I honeslty believe is real. It's a problem yo. Should probably see some mental health for that.
User avatar #4456 - defectivedetective (04/20/2015) [-]
No idea where to go but do you guys have any tips on studying general chemistry? I have been on a pretty bad roll with getting professors who shows problems without really explaining them and I got the acs exam coming up in two weeks.
User avatar #4457 to #4456 - berengar (04/20/2015) [-]
If you bought the book, use it. Most of them tend to give very good ideas about the basics of the test. Also, if your professors have office hours, and you don't mind talking to them, do that as well. Other than that, just study and you should be fine.
#4454 - phanactssonjoe (04/19/2015) [-]
why do we need to do all these things before planting seeds? like hang them upside down for 2 weeks and soak it in water for like another 2 weeks for pineapple, let dry with like the skin on it for avodcado, etc. how do wild trees, fruits and veggies ever grow on their own? ( i read you can grow a avacado tree with just the seed but have to do something with the skin otherwise it wont grow more avacados)

My joints are always killing me when I smoke weed. Is there a reason behind this? Should I stop?
User avatar #4446 to #4445 - dudeheit (04/16/2015) [-]
Well killing you in meaning of "Dude I am waaaaaaaaaaay to high" or in the maning of that your hearts starts beating faster and you have anxious thoughts??
In both cases I would start lowering the amount of dope you put in, if it still doesn't change stop or go see a doctor.
#4447 to #4446 - thtguyfromwork (04/16/2015) [-]
Na, anytime Im high they hurt. Whether Im high as balls, or have a good buzz goin.
User avatar #4448 to #4447 - dudeheit (04/16/2015) [-]
Then go for option two: Stop and/or go see a doctor.

Question

In what world is "Nuclear" cleaner than Coal or Oil

When you burn Coal or Oil it releases Co2 which can easily be disposed of thru Co2 devouring plants. When you need to cool down Radiation you need to dump the waste somewhere and that waste doesn't go away for like 150 years.

So anyone who thinks Nuclear is cleaner than Coal is a fucking idiot.
User avatar #4452 to #4442 - nimba (04/18/2015) [-]
>"coal"
User avatar #4450 to #4442 - theuntakenusername (04/18/2015) [-]
Both are pretty shitty.

The waste from coal plants(CO2 alongside some minor oxides and water) is spread through the atmosphere, while from a nuclear plant most of the waste can be either reused(medicin, science) or can be stored without it ever having to impose a risk on society. So normally nuclear is cleaner, until one of the nuclear reactors or deposits fail.

You're more likely to die from air pollution due to combustion, than from radioactivity.

Hi.
I got a job offer to do some graphics in photoshop plus coding in PHP(because there is not much work to do with the graphics). I am an IT student but I dont know how to code in PHP. I know basics of C++, pascal, HTML, SQL and C. I want to learn PHP as fast as possible(they require basic knowledge and expect me to learn fast while I ll be working there). Any free internet courses you know? I know only codecademy, but its weird because it basically only learns you how to code in any language.
They work on e-shop.

Hey sciencexplain, I need a little help here, could you tell me how But-1-ene reacts with Hydrogen Flouride?


Or anyone else for that matter?
#4434 to #4431 - berengar (04/14/2015) [-]
You are looking at a H-X type reaction. It is an electrophilic type of a reaction and it follows Markovnikov's rule. What happens is because the bond from H to F favors F, because Fluorine is so electronegative, this enables the double bond in but-1-ene to attack the Hydrogen and form a carbocation intermediate. The carbocation intermediate then is attacked by the negatively charged Fluorine to form the product, 2-fluorobentane.
User avatar #4439 to #4434 - sciencexplain (04/14/2015) [-]
Thanks for stepping in for me.
User avatar #4440 to #4439 - berengar (04/14/2015) [-]
No problem, I am in Organic Chemistry right now, so all this stuff is fresh in my mind.

How can we map Dark Matter when its a hypothetical type of matter?
#4444 to #4430 - thtguyfromwork (04/16/2015) [-]
Not 100% sure, but I think it's mapped by the fact that there's a lack of matter in these areas

So i've been thinking about time-travel recently. Mostly i think that even if we found a way, humanity would outlaw it completely, or someone already has done it to get rich and or famous. In either event, i was wondering what would be the possibilities of time travel.

1. we go back in time and create the problem or incident we wish to stop or avoid. I.E.you go back to stop from failing a test, and create the reason you fail. Maybe you were late because you got stuck in traffic, made by you going back to stop it.
2. We create an endless loop where the event of time travel both occurs and doesn't occur. I.E. Imagine terminator if he goes back, kills sarah connor, so they don't send him back, which means she didn't die and they do need to send him back, etc... at nauseum.
3.You actually do change the future by changing the past. While i like the idea, i think its impractical. If i go back to high school to date a girl i didnt, i woudl create a new timeline where that event occured, and it destroys the one we live in, or creates it based on your frame of reference.

I think ethically we can only assume people who WOULD change the past, would do it for themselves. They arent going to kill hitler, they want to be rich. This both creates a horrible timeline in which someone who is a bad person gets rewarded but the nice people get punished. Plus i've always like the idea the order of events is set in stone so to speak. Like we have choice, but ultimately its already been written down somewhere what will happen.

time travels weird huh bitches...

I guess my question is, could you really create a battery like they did in the first season of breaking bad?

A couple of films you may be interested in, Looper (Outlawed time travel and crossing paths with future self etc.) and Predestination (Causing events that fucked you up in the first place, and more tasty plot twists!)

since it's bad to stare at the sun, would it be just as bad to stare if it turned into a red sun?
User avatar #4428 to #4426 - berengar (04/13/2015) [-]
Not quite as bad, but still bad. Also we would all be dead by this point.

Hey guys, sciencexplain maybe?

A while back i saw a ''this week in science' post on FJ. It said something about water having more then the 3 traditional phases solid liquid and gas.

Im trying to find it but i cant, anybody know what im talking about that can provide sauce? It would really help with my study
User avatar #4422 to #4421 - sciencexplain (04/09/2015) [-]
I can't find the exact image you want, but I can tell you that there are more than 3 states of matter. You have 4 primary ones, solid, liquid, gas and plasma. There are other different states of matter like Bose-Einstein condensates, neutron-degenerate, liquid crystal, microphase, quantum spin and all that shit. There are also theoretical ones, but if you're interested in states of matter, look some of them up. They're pretty fucking neato.

en.wikipedia.org/wiki/Time_dilation

would it be ridiculous to think that if you wanted to live to a certain year you could use time dilation to live to say, the year 2300 or something like that?
#4413 to #4412 - smudgiemuffins ONLINE (04/08/2015) [-]
That's exactly what that means, granted you could travel near enough the speed of light.

It should be noted, you haven't "traveled 300 years in the future." If you're moving fast enough, it's entirely possible that only one second has truly passed in your reference frame. Your observation of time isn't an illusion or invalid, it's as valid as measuring time from any other reference frame.

But yes, in principal if you zipped around the earth a couple times at a really high speed then slowed back down, everyone you talk to could say it's 2300 when you have accurately measured that only a minute has passed.
User avatar #4414 to #4413 - bionicpanda ONLINE (04/08/2015) [-]
Isn't Time Dilation increased drastically when near a black hole?
#4415 to #4414 - smudgiemuffins ONLINE (04/08/2015) [-]
It is indeed. In fact, not just black holes, but all gravitational fields do that. One of the first major observational confirmations for general relativity was the incredibly elliptical orbit of mercury that Newton's gravitational theory didn't predict.
User avatar #4416 to #4415 - bionicpanda ONLINE (04/08/2015) [-]
So could time dilation actually be used to our benefit? Like could someone actually live to a certain year manipulating it? Ambitious or not, it sounds like it could.
#4417 to #4416 - smudgiemuffins ONLINE (04/08/2015) [-]
I can't really think of any interesting uses. Your ideas are as good as mine. But yes, there isn't any reason you couldn't live to what everyone else would call the year 2300 and still be the same age. From a practicality standpoint, what would be the point?
User avatar #4418 to #4417 - bionicpanda ONLINE (04/08/2015) [-]
Besides the fact that it would be totally kick ass?

No cure for your terminal illness? Get send to a time where a more medically advanced humanity can save you.

^ Only benefit i could think of atm
User avatar #4419 to #4418 - sugoi (04/08/2015) [-]
There are a few issues with that.
>You don't know when the cure will be invented (or invented at all).
>You don't know if you have the funds to pay for the treatment.
>Everyone you know could be dead

Just doesn't seem worth it unless you're skipping like, a week so you don't have to wait for the newest games to be released.

Or you really can't wait to watch game of thrones.
User avatar #4420 to #4419 - bionicpanda ONLINE (04/09/2015) [-]
tbh I'd go to the year 2300 right fucking now if i could.

I have a lot of loved ones, but the future is probably kick ass
User avatar #4423 to #4420 - loomiss (04/10/2015) [-]
you fuck hot future chick
later find out she is great great great great great etc... grand daughter
