If ESP was shown to have a statistically significant effect, what mechanism would you propose to explain it?

Hey /sci/, Just wanted to get your opinion on something. The invention of the integrated circuit has had a profound impact on our lives; moreover, since the invention of these devices, they have increased in calculations per second exponentially, whilst requiring massively less power to run. The general availability and low cost of computing devices has spawned a generation of computer hobbyists, often called the Open Source Movement, who, by sheer force of numbers working on a project, have produced software of a standard typically only seen from commercial institutions. Recently, scientists have developed "digital microfluidics devices". These devices use electrodes embedded in super hydrophobic polymers to alter the "wettability" of it's surface, allowing discrete droplets of aqueous solutions to be split and reformed on it's surface, and a number of lab operations to be performed on those droplets. If the technologies promise is realised, we could one day have a full "lab-on-a-chip", with practically any operation performed in a laboratory capable of being performed by the device. Given that I'm only trained as a biologist, I would like to get the opinions of sci, who may know more about chip fabrication than myself- Is a full lab on a chip device possible? If so, would the same exponential increase in power apply to them? If mass produced lab on a chip devices became cheap and readily available, would it spawn an "Open Source" revolution in biotech?

\zeta(s)=\sum_{n=1}^\infty \frac{1}{n^s}=\prod_{p prime} \frac{1}{1-p^{-s}} So /sci/, how to solve Riemann's hypothesis? It seems like the only feasible millennium question.

Studying mathematics/theoretical physics as a hobby

12 posts and 0 image replies omitted. Click to view.
Does anyone else study mathematics or theoretical physics as a hobby on top of work? How do you pace yourself and stay motivated without the support system of an academic environment?

Just wondering /sci/ are antidepressants really bad for you? My friend who is a psychology major said they were, but I didn't get a chance to ask why. What are the alternatives to them actually backed by science if this is indeed the case?

How come academia is for pro-state beliefs, and not for humanity's beliefs?

How should I keep my food cool?

I have a well insulated cooler and a neighbor with a freezer. I am currently freezing a bag of water in this freezer every day, taking it out, and putting it into my cooler. I then take out the bag of water from the cooler and put it in his freezer. Is there a better way to mooch off of his freezer? Pls help with science. Pic unrelated, unless you guys want to talk about penny farthing bike riding.

There is this sci-fi anime where they let out this gas so you can't use guns, and then everybody draws axes instead at goes at each other. I like this, and want to do something similar in a story. If you wanted to keep people around you from firing their guns, what gas would be best to release? I know apparently hydrogen wouldn't be that effective ...

Say for each object X, there... 1 posts and 0 image replies omitted. Click to view.
Say for each object X, there is a terminal morphism from F to X. Does this alone already imply that there is an adjoint G going in the other direction? And if yes, it's not unique, is it?

/lit/ here. Sup /sci/? I was watching TV when a commercial came on for a new movie, Lucy. It starts off in Morgan Freeman's voice saying, "Humans only use 10% of their brains...." Now, I remember reading a science article saying this was not true, that we use our WHOLE brain. Is this movie bullshit, made for the scientific illiterate?

/sci/, as a long time lurker, and a highschool student, I have often come accross things on here that I do not understand, nor do I pretend to, but what I have come to realise is that you bunch are pretty smart cookies. If you're as smart as I think, then maybe you'd be able to help me with pic related. I saw a test thread on here a while ago, and it looked a heck of alot harder than this, but for the life of me I cant discern how to find the stationary points when theres nothing to make 0 equal to, unless I've been using logs incorrectly. A thousand blessings in thanks. If you deem the subject matter to not be worth your time, then I understand.

Geometry problem

7 posts and 0 image replies omitted. Click to view.
There are 4 points A, B, C and D on a plane. I am looking for point E. The distances AE, BE, CE and DE should be the same (as far as possible). The total distance AE+BE+CE+DE should be as small as possible. I know there is no such point. But how could you go about solving this?

Mathematical Logic

So, if one were to study mathematics on their own, would mathematical logic be the best place to start? It seems to me like math is applied symbolic logic used to study patterns. Would one's self-study be best started by going through an intro book on that?

Is there a relatively easy way to build a simple spectrometer? Not high tech lab shit, just something I can fuck around with?

pressure waves and body armor

hello /sci, i come to you from /v/ with a bit of a problem we're trying to figure out how the "gel" layer in master chief's armor would allow him to survive the impact from his regular falls from space and rockets to the face by moving the shockwave around his body to prevent injury. but being from /v/ we have no idea how pressure waves move and we need your help explaining how his armor could work to accomplish this feat. link to thread: >>>/v/253279542

What is the speed of electricity in a vacuum?

I'm taking part in the EPQ where I research and write a 5000 word essay about any topic of my choice. I'm doing something around Astrophysics, but there's so much choice and I need help to narrow it down. Ideas so far: Dark Matter Methods of searching for Exo-Planets The Alcubierre drive The CMB I was advised to do something of current interest, so these are all quite plebby, but it's not a necessity. Other suggestions are encouraged.
