Titan also has a really dense and humid atmosphere also with the low gravity you could practically fly on titan if you taped wings to your arm. It's irrelevant but I thought you would like to know.

any physics/math majors out there? i'm working on what is a really simple calc 2 problem but i've run into a little bit of a misunderstanding. the problem is asking how much work would be required to pump water out of a cylinder. however, the problem is that i have only ever worked in SI units and all the examples in class were SI units while the homework question is in FPS units. is it safe to assume that force pounds equals lbm = lbf because a and gc would cancel out in the equation F = ma/gc? i can provide the question and my work if that helps

Shit nigga i'm more space stuff, i'll try though.

Don't let global climate change affect your life too much. You aren't really causing that much more pollution by using basic electronic devices. Just try to do simple stuff like turning off lights when you leave rooms or whatever.

How to trees evolve? Or plants I'm general.
They produce asexually so the offspring have the be exactly the same as the mother tree... Right? Or is it something more too it? Because there loads of different trees out there that have evolved to fit different climates. Did they developed it in their own? But how do they do that when they produce asexually?
User avatar #2607 to #2579 - kanadetenshi ONLINE (5 hours ago) [-]
Plants do not reproduce asexually, they have different gametes. But even then asexual lifeforms can still evolve through genetic mutations (which is why single celled organisms evolved in the first place)

I'm fairly sure that flatulence is almost entirely governed by dietary habits. So I figure you probably started eating differently.

Not really science, just beer:
Hey I'm brewing beer for the first time with a shitty home setup, the stuff is still fermenting and all but I'm wondering about how to get the yeast and leftover shit out.
Would a brita filter work or do i need to shell out fuckin $300 for a piece of plastic and a pump?
User avatar #2574 to #2540 - xsnowshark (07/21/2014) [-]
What kind of brew are you going for?
User avatar #2541 to #2540 - subtard (07/21/2014) [-]
If you're bottling it, homebrew will always have a little sediment in it. Any filtering will mean the yeast won't be able to carbonate the beer later

**Orc rolled image** Why is Pluto not a planet? I know it stopped being one around 2006 or so, but why? How could they just suddenly decide that it didn't meet the qualifications. I read up on it a little bit, but I really don't remember anymore, and feel like someone explaining it to me would be better.
User avatar #2593 to #2542 - jokeface (07/23/2014) [-]
Pluto isn't a planet for the same reason midgets aren't people.

I'm astronomyexplain, i just don't feel like logging out and back in.

What leightonsolomon said, it's too small to be a planet. It's also theorized pluto may have been a captured Kupier belt planet as well. Pluto was also given a new name when it was demoted, and is now officially known as 134340 Pluto.

IC 1396A
#2557 to #2556 - Orc (07/21/2014) [-]
**Orc rolled image** They couldn't tell that it was too small in the first place?
User avatar #2558 to #2557 - djequalizee (07/21/2014) [-]
Basically it's always been kind of sketchy if pluto should be considered a planet or not. The breaking point was in 2005 when astronomers discovered UB313, later named Eris, even farther than pluto. It was 25% more massive than pluto. Basically they either had to make Eris a planet, or decide that Pluto wasn't a planet. Scientists came up with 3 qualifications that a body would have to meet in order to become a planet

t needs to be in orbit around the Sun

It needs to have enough gravity to pull itself into a spherical shape

It needs to have “cleared the neighborhood” of its orbit

Pluto does not meet the third rule. Planets like Earth are the dominant body of their orbit. Typically they will either pull objects in or fling them into space. Pluto is only 0.07 times the mass of the other objects in its orbit. The Earth, in comparison, has 1.7 million times the mass of the other objects in its orbit. Planets who don't meet the third qualification are then considered dwarf planets. Hope this helps.

#2543 to #2542 - leightonsolomon (07/21/2014) [-]
Because if pluto is considered a planet, then we have to make all the other dwarfs planets. Plutos demotion was because of the discovery of many more "planets"
Plus the thing is the size of a moon, it should have never been considered a planet.
#2546 to #2543 - Orc (07/21/2014) [-]

If you were to throw an electron and a proton at a neutron star, would it just be a really heavy isotope of hydrogen?
#2555 to #2539 - djequalizee (07/21/2014) [-]
I'm astronomyexplain, i just don't feel like logging out and back in.


No, neutron stars are not purely made of neutrons. Typically about 10% of a neutron star consists of protons and electrons.

By mass or number of particles?
User avatar #2560 to #2559 - djequalizee (07/21/2014) [-]
I believe it's mass. Don't quote me on that though.

en.wikipedia.org/wiki/Rare_Earth_hypothesis

I want you to read this.

This universe is unfit for life. Had anything different happened during the Big Bang, life could have been impossible.

This thought only saddens me due to the multiverse theory.

Somewhere, in another universe, life is teeming, because everything went right when their universe came to be.
User avatar #2544 to #2525 - leightonsolomon (07/21/2014) [-]
That's... depressing. But recently NASA announced that statistically, our galaxy alone has 100 million earth like planets that are more than capable of life. Even if life requires ridiculous circumstances, it's probable that it exists in many other places in our universe.

Dunno if this is the right place to ask, but can someone explain what cradle-to-cradle is and how an idea/design can be considered cradle-to-cradle
User avatar #2521 to #2520 - monstrumologist (07/19/2014) [-]
what if I say "I want to make a shoe made from worn out tires!", is that cradle to cradle?
#2528 to #2521 - anonymous (07/20/2014) [-]
Cradle to cradle basically means that our waste products should become the resource materials for something different so that we don't deplete the world's resources.

The guy who came up with "cradle to cradle" (William McDonough) gave a lecture about it at my school.
When students asked him how we could manage to achieve this he had no answers.

I think the guy is just some pretentious asshole who thinks he reinvented the concept of recycling but has no real solutions
User avatar #2529 to #2528 - monstrumologist (07/20/2014) [-]
are you kidding me? no fuckin answer?!
We're expected to write a fuckin case study on this shit. Best part is this was never discussed in class. So, basically, we're writing case studies based on something that was never explained to us..
fuckin bullshit.
#2530 to #2529 - anonymous (07/20/2014) [-]
Well they did write a book about it .
en.wikipedia.org/wiki/Cradle_to_Cradle:_Remaking_the_Way_We_Make_Things

You might find something usefill in there.

I've never read the book, everything i know about C2C i learned from that lecture and a couple of articles i've read

#2524 to #2521 - anonymous (07/19/2014) [-]
It means self sustaining, I think. Like trees die and turn to compost which help other trees and plants, nothing at all being wasted. So I don't think shoes made from worn out tires count because they'd eventually become useless.

Good evening FJ, I have one question for you:
About the airplane crashed in Ukraine, many of you already know that it contained most of greatest authority about HIV, and someone already said that it was put down on purpose because of those passengers.
Considerated that this is not the first time that a large group of researchers about HIV die or disappear, what do you guys think?
I just want to hear an opinion

Okay science people, Have you ever had a dream about something that have yet to happen but you don't remember dreaming about it until it actually happens?

I have it quite a lot, its actually called "DeJa Vu" dreams, unlike Lucid dreams you don't know you're dreaming when you have them because everything is exactly the same as real life but in the very distant future (a month at best)

Have you tried to alter the outcome of that said dream somehow ? I did, and it actually changed, the person who was with me thought I was weird for leaving the room suddenly.

Its never about important things though, just mundane things like "Seeing person #1 walking in the room" or "Having a text message sent from facebook"


Also another phenomenon, does anyone here say "jee i wonder what time it is" and every time they look at the time its exactly 11:11 ? every. single. time.
I'm guessing its just "Brain time" something your mind does repetitively at the exact same moment without you knowing.
User avatar #2545 to #2513 - leightonsolomon (07/21/2014) [-]
Thats just because you tend to remember these things. So many mundane things happen everyday, if you happen to look at the clock at 11:11, you'll remember it, even though you looked at the clock 58 times before that day.
#2523 to #2513 - dehumanizer (07/19/2014) [-]
eh not really i would call it coincidence, you just remembered those things becuase you wanted to (things that happened in your dreams, exact time numbers).
User avatar #2550 to #2523 - pulluspardus (07/21/2014) [-]
then why do i dream them BEFORE they happen?
#2551 to #2550 - dehumanizer (07/21/2014) [-]
you dream about something and when it happens you remember you dreamed about it, its you thats making a connection
User avatar #2552 to #2551 - pulluspardus (07/21/2014) [-]
but how does it happen at the exact moment and the exact time and the same exact situation?
User avatar #2562 to #2552 - grandlordchicken ONLINE (07/21/2014) [-]
How do you know it's the exact time, exact place, and exact situation, did you know the time and place in the dream? Is the situation even really exactly the same or are you just remember the parts that happened? Memory is a funny thing, it's changed every time you remember it.
User avatar #2567 to #2562 - pulluspardus (07/21/2014) [-]
because it is the same exact moment happening twice.
People saying the same exact things, at the same time and on the same place and also the same clothing same, same atmosphere same everything.
Memory is a funny thing true, but I always remember it when it hits.
User avatar #2568 to #2567 - grandlordchicken ONLINE (07/21/2014) [-]
First of all, how do you know it's at the right time, is there a calendar and a clock in your dream? Do you actually remember the color and type of that persons shirt in the dream? I find dreams usually aren't that lucid. Do you actually remember the exact words they said in the dream? What else happens in this dream? How many dreams do you have that AREN'T predicting things? One common thing that can happen is that a lot of things happen in a dream, and then later one of those things happens in real life by coincidence, and you only remember the part of the dream in which it happened because that's the part that happened in real life. How often do you do the same routines day by day? Something may happen in your day, so your dream about it, and then something similar happens another day and you think the dream predicted it.
User avatar #2569 to #2568 - pulluspardus (07/21/2014) [-]
Sometimes (I look at my watch and stuff)
Yes
Yes
I have a lot of dreams that don't happen of course, and I am not saying i predict things, just some odd dreams that actually happen in the future
I don't do the same routines day by day, I'm talking to you now saying these exact words and i will never say these exact words ever again.

I'm not actually a spiritual person , I don't believe in ghosts and angels and what not, just want to know the science behind this stuff there must be.
User avatar #2571 to #2569 - grandlordchicken ONLINE (07/21/2014) [-]
The actual science behind this is the simple fact that we remember the things from dreams that happen more than the things that don't, and we have a lot of dreams and a lot of things happen, so coincidences happen. If you really want to get an accurate picture record everything that happens in every dream you have as soon as you wake up. Then when record it when the things happen, you'll find that the things that don't happen FAR outnumber the things that do. If the there is a huge amount of things in your dreams happening in real life, contact James randi, he has a million dollars for you.

Why is the sky blue?
User avatar #2516 to #2511 - xtwinblade (07/19/2014) [-]
When sunlight hits our atmosphere it refracts light, mostly blue and violet light, this slightly decreases the colour blue in the image of the sun we see from the ground, leaving it in an orange/yellow coloured look.

Why's water wet?
User avatar #2572 to #2515 - djequalizee (07/21/2014) [-]
Water is a dipole. Basically the oxygen is slightly negative and the hydrogen is slightly positive. So it attracts other water molecules, making it want to be near other water molecules. So that's why water sticks to you and makes you wet.
