hey /scientists/, science amateur here I'm not really well versed or knowledgeable about science and physics , astronomy, biology, and metaphysical stuff, can some of you who know and understand science and physics explain to me the different theories and discoveries and experiments they have on things like multiverse, parallel universes, transcendence and multiple realities, I know science has its limits and their are very hard borders on what science can do or can't do or can show or can't show or can prove or can't prove. I know the universe is big and mysterious and cool and amazing in the way it works but I really want to understand it and know how the universe works and whats the nature of it and how we as physical beings experience the universe and its places and times and areas. I know they say how we can be apart of the universe or how we can transcend time and space as spirits and be in different places or different times or even different universes and realities at different places of time and times of places. I know some things are just theoretical or they're just an idea or they're just speculative but they also say theories and ideas are kind of the same thing as realities and that energy is just manifested in different forms and that theres a source of everything and if we can access the source we can be apart of everyone and everything and everyplace and everytime and every idea, please help me /sci/.... I really want to understand physics and quantum stuff and all the big things like the nature of our existence and how realities and the idea of space and time and reality and theory work and exist with parallel universes or multiverses or infinite realities please help me /sci/.... I really want to know and understand this stuff......

How do you deal with the fact that most of problems in math are either solved or really hard? There's no room for research unless you're memechizuki or you're willing to think up and solve some irrelevant problem just to publish a shitty article that no one will ever be interested in
i was thinking about a particular problem for some time, today i made a google search and some faggot wrote down the same thing 100 years ago

I have terrible discipline.

What's the longest amount of time you've spent on a single maths/physics/engineering problem?

Be honest.

How bad is being happy for you?

Take a look at these brainscans, Left is someone doing something they enjoy doing (irrespective of which activities were studied, such as watching movies, playing sport, talking with friends), Right is someone abusing cocaine.

Notice that the cocaine user doesn't even generate near the amount of chemicals in his/her brain than the one doing an enjoyable activity (red indicates higher concentration)

Should we be regulating entertainment to limit this effect? Kids nowadays are growing up with access to so much happiness that their brains are literally flooded with chemicals, ending up worse than cocaine addicts.

XX = male
XY = female
YY = yo wuddafuck

Seriously, what would the result be? I mean, i know it's not possible, but what would happen? I've heard that you need the X chromosome to live. But, still... would you just be a lifeless blob? something would be created, but i have no idea what...

your thoughts, /sci/?

Ecoponics basically transforms biowaste into fishfood. In normal aquaponics, the main products are plants and fish, in ecoponics the main product is just fish.

Biowaste is delivered into the facility. Then it is transformed into animal protein, by feeding snails and earthworms. Also Kashimori (Bokashi or Effective Microbes) is used.

Normal composting destroys all pathogens.

The nutritional liquid, which is formed by the process, will be fed to spirulina-algae.

In the aquaponics system, there will grow hemps and chiles.

Hemp is grown for the seed and chiles are used for their leafs which have D2- and D3-vitamins.

Now we make a food to the fish with these: earthworms (42%), snails (18%), hempseed (30%) spirulina (5%) and chilileafs (5%).

The shell of the snail is needed for the skeleton of the fish.

Also the factory will be closed from outer air. So CO2 and 02 will be at balance. This way we can produce fish, that has minimal enviromental poisons + many other benefits.

Also some structural changes in aquaponics system itself are made.

I made all the calculations of the vitamins and looks good. It is in Finnish, but we are making this to english soon.

If you are interested on the project and could help in some way, please contact me henri.lentonen at gmail

If someone gave you a blank cheque to do whatever experiment you wanted what would you do?

I'd love to send more Curiosity style drones to all our planets, I would love to see more images of Venus's surface and the clouds of Jupiter.

Can anyone give me a good reason for why one would binarize a graph before computing graph-theoretical measures such as the clustering coefficient or transitivity? Don't weighted variants of these measures exist? Why would you binarize the graph first?

A week ago, I derived pic related, then extended it to
[math] \displaystyle (1-a)^{-1}= \prod_{n=0}^{ \infty}(1+a^{3^n}+a^{3^n2})[/math]
then to
[math] \displaystyle (1-a)^{-1}= \prod_{n=0}^{ \infty}(1+a^{4^n}+a^{4^n2}+a^{4^n3})[/math]
then generalised it to
[math] \displaystyle (1-a)^{-1}= \prod_{n=0}^{ \infty} \sum_{j=1}^{k}a^{k^n(k-j)}[/math]
for [math]|a|<1<k \epsilon \mathbb{N}[/math]
amirite?

Serious question, Anon.

I'm glad i don't have an erection problem yet but i still have a problem.
A problem with my dick.

I have, somehow, "broken" my ejaculation module, per se.
I don't know jack on biology so i don't know which part around the prostate manages the pumping but my ejaculation has become weak over the years.

What can be the cause ? Can it be fixed ?
Dick and I thank you.
