Why is it not allowed to be a fucking speculative on this board?
>post or theorize about ANYTHING which isn't well documented
>your entire thread is spammed with people who fell for the college spook and only know how to parrot what their textbooks say
The fuck?
prolly cuz ur not basing ur speculations on anything solid or testable. topics like those, everyone feels like they can throw opinions out there

>Why is it not allowed to be a fucking speculative on this board?
Because 100% of the time it "speculate" and "theorise" are just euphemisms for "here's some unsubstantiated crap I thought of while sitting on the shitter". No one does anything other than present some (often) poorly thought out idea, never do people attempt to write down some mathematics and show some implications of their idea.
You know who does a good job theorizing and speculating? People with some knowledge of the subject and it's history.
Alright anons, so right now there aren't a lot of good boards on /sci/. There's a good couple, but other than that this whole place is just nope. I've come to fix that.
As of late, something has been on my mind, but I haven't been able to put it into words. Perhaps until now. I'm just going to cut to the chase.
The reverse butterfly affect.
Let's take a look at the butterfly effect. We observe a butterfly in Beijing. Every time it's wings flap, what the weather will be in New York changes. And, this may be true. It's the strangest phenomena, known as the butterfly affect in chaos theory. The absolute smallest differences can throw an entire operation off or change the affect of an event, making the outcome different from another identical event. Chaos theory is a field of physics which focuses on nonlinear equations and probability, and it's this field that applies to things like guessing the weather. Most physical phenomena are measurable and predictable, however not all phenomena can be linearly guessed. Chaos theory not only focused on observing unstable phenomena, but also in predicting the future. Where would a double suspended pendulum be if we dropped it from a certain angle? We can't really know as inputs need to be filled out.
Now, the normal butterfly affect and chaos theory focus on predicting the future.
What I'm thinking of focuses on reading the past.
Let's observe the Big Bang theory. We all know what it is, so I won't go in depth explaining it. However, when we look at how one would go about developing it, you basically just look at the patterns of stellar and galactic movement and reverse it. When we do this, all we can understand is that everything was once wrapped up really tight in a ball.
[Pretyped, way over character limit, will continue.]
>>8173439 cont.
However, the difference between studying the Big Bang hypothesis and my idea for the reverse butterfly affect focuses on nonlinear equations. The reason we can't really formulate the nonlinear equations in chaos theory mathematics is because there are open inputs that still need to be filled. However that's just about predicting the future. There's no need to (mathematically) predict the past, as it's already happened. This would mean that the inputs for said nonlinear equations would already be filled! If the inputs, which would otherwise be unguessable, be filled, we'd be able to reverse the nonlinear equation and be able to see exactly what caused an event.
Now, this is utterly useless if you want to apply it to what ordinary chaos theoretical physics focuses on. However, there are other areas this could be used.
We could use this method in the biochemistry field and take what's left of broken down matter and reassemble the genome of long extinct creatures (Jurassic park anyone?), or use it in the Naval or AirForce to be used as kind of a reverse tracking method (allowing someone to test an area of air or water and see if an enemy craft has previously trespassed). It could be used in detective work and allow us to open the gates for computer ran law enforcement or allow us to read the unclear history of other planets. All it would take is the help of some computers.
So, what now? What do you guys think? Where can we improve upon this theory? Help me out with this guys, I want today to be the day 4chan made a huge ass contribution to the scientific community. Discuss.
You don't understand non-linear equations, you don't understand Chaos theory and surely you don't understand how mathematics work. Your idea is laughable to say the least. Delete this post, you're making a fool of yourself.
>>8173471
Fuck you too anon.
Can you at least nitpick instead of just give up? I'm looking for input here. I'm not the average faggot who'll just shut out constructive criticism. I'm looking for exactly why the whole concept sucks and deserves removal from these boards, as you put it.
Never mind faster than light travel.
Is it possible for us to travel at light speed? Half light speed, a quarter of light speed?
That's all we'd really need to explore the nearest stars.
No, maybe and yes.

No, yes, and yes.
I'm a chemist and my cousin, younger than me by 12 years, has asked me for a semestral project they could do. For the love of me, I've been doing post-grad work for the past six years that I can't recommend stuff she could do anymore. I don't want to disappoint so I'm asking for ideas for projects.
They will be in a group of 4 iirc. The project can run for about 2-3 months. They have access to a chemical laboratory.
To give an idea of the level of research they can do, they extracted from leaves last year and tested that for anti-bacterial properties.
>>8172966
This is a short project idea but what about the separation of acetic acid from pyro oil/biocrude? (via extraction and/or distillaiton)
They could use some kind of oil (vegetable or other kitchen oil) to simulate the pyro oil and just add vinegar to it.
For example, they can add water and separate aq phase from the organic phase. Then they measure the amount of acetic acid extracted by the pH. (they could obtain the pH by titration or a calibrated pH probe)
They could check the effects of T, P, acetic acid concentration, or something on the fraction of separation.
>>8172966
Extraction of volatile compounds (like limonene) from fruits
Extraction and identification of lipids, using TLC
Synthesis of aspirin
Coating metal with gold/silver/copper through electrolysis
Extraction of DNA/RNA
Reaction kinetics
Don't.
Labs are dangerous and high schoolers are braindead idiots.
Not to mention you won't learn abything useful in the lab if you don't know anyhing.

Fug me /sci/, I ended up missing a class in the physical science section of my major. I'm not particularly interested in any of these, but I hope you guys can steer me into the most useful/interesting one for a dude who loves comp sci & math.
My options are:
Environmental Science:
Relationship of living organisms to the environment, including human impact on the atmosphere, hydrosphere, lithosphere and biosphere. Emphasis is placed on understanding of biological and physical science issues currently faced by society.
GEOGRAPHY:
Introduction to the natural environment from a geographical perspective. Topics include geographic techniques, and their use to study air, water, land and life forms, with emphasis on their interconnections, interactions and world location patterns.
GEOLOGY:
Dynamic processes governing the origin and development of the features of the earth's surface and interior. Identification of common rocks and minerals, introduction to topographic maps.
What should I go with?
side note: I can take a geog honors class, or a geol class with a proff who has high ratings on RMP. Environmental science, I dont even

Ok, I have tried to understand cell complexes from Hatcher's book.
I have no problem to understand how this torus is made as quotient space, but...
he says to imagine interior of polygon on the picture as open disk ( I assume in R^2) which is attached to union of two circles ( with one point in common? ).
So, is basically 1-cell a line, 2-cell a disk in R^2 and n-cell open disk in R^n?
Do I simply take wedge of two circles and put disk around them, put it in oven and it suddenly gains height?
>>8172148
The beauty of CW complexes is in the attaching maps. So, you look at how the boundary of the disk (so, a 1-sphere) is attached to the wedge of circles. What map S^1 —> (S^1 V S^1) produces a torus when you fill in the boundary you just mapped onto the 1-skeleton?
Hatcher is a shit tier book.
>>8172179
so there is a single point on the boundary of disk which is common point for two circles? Feels like I need to turn disk inside out.
What's the likelihood of the new mini ice age people are talking about?
I mean, we were worried about the exact opposite five years ago, so forgive me if I take climate science with an ocean of salt.

It's a cycle of media propaganda.
They said the same thing in the 70s starting with warming and concluding cooling. Neither happened

Could you be slightly more informative than a fortune cookie, pls?
How do you deal with people who use magical thinking instead of developing a probably explanation for every single fucking thing they say? How do people like Bill Nye and Sam Harris and Lawrence Krauss and Christopher Hitchens and Morgan Freedman and Carl Sagan and Neil Degrass Tyson and whoever have so much patience for these people? I don't, I just can't fucking stand them and I want to fucking strangle them because they're so annoying, in fact I lament the fact that I live in a society that doesn't base what it thinks on logic and probability, or just accepting what they don't know, I lament it every single day. How could you not, if you have any capacity for contemplating the world around you at all? You think I'm fucking around with this thread but I'm serious, this is a real issue that I want someone to help me out with.
Le simple thought is easier
>>8171976
>talks about logic and probability
>P(OP is a brainlet)=1.0
>>8171986
You know what I mean by probability. I'm not a scientist, but you can only give the best possible answer based on what you already know, and you accept that it may not be true if you don't have enough evidence to confirm it. Although when there's a blind spot in a lot of people's understandings, they just fill in the blanks with some other explanation, like consciousness for example. They like to say that consciousness exists outside of this world. WHAT!?!?? NO!!! That's the most retarded thing I've ever heard, it's like I want to punch people when they get this stupid.
Is Newtonian physics a meme?
>>8171866
Do you know what a meme is?
In the two-slit experiment, one particle is said to pass through both slots, to form the interference pattern. But each particle leaves a point-like mark on the screen, doesn't it? And the interference pattern is formed with time. Wouldn't it be more logical to suggest, that the interference pattern is formed due to some wave-like properties of time? So each particle passes through one slot, but we do not know which one.
>>8171733
>So each particle passes through one slot, but we do not know which one.
that's exactly what happens.
I don't know why you thought otherwise in the first place.
One photon doesn't create an interference pattern.
10 photons don't create an interference pattern.
you need a lot more.
But the probability of each single photon of being at a certain position on the screen follows the pattern.

Not really. Take a look at the path integral formulation of quantum mechanics and see what Feynman and HIbbs says on the double slit experiment.

Is economics even a science? Are they lesser creatures compared to us physics and engineering majors?
>>8171625
As someone who majored in math and Econ, at best it's soft science, at worst its sociology. It's not a science in the same way that chemistry and bio are, but that doesn't mean it's not fairly rigorous and useful (given its assumptions). Higher level Econ is also intellectually stimulating, which is what drives people away from that. It's a shame, really. I think I saw here on /sci/ or somewhere that someone was asked, "if you're so smart why are you in Econ? Why didn't you do engineering?" And it's exactly this mindset that overpopulated Econ with dribbling children; it becomes a reject school.
>>8171625

No, they choose a model based on previously held ideology, and then accept anything that model seems to say to them.
