I think we may all be dead for witnessing the day, however, I do think that humanity will become AT LEAST interstellar and hopefully intergalactic.

Though, outside of a miracle we will always be trapped within our gravitationally bound Local Group.

is infinity real?

It is a notion created by humans to understand extremes

Given sufficently big or small mesurment units, everything could be mesured

Even expanding universe has a constant size in small enough time interval, but that interval has to be infinitly small and here we go with infinity in definiton of infinitly, shit

t. Drunk brainlet

Based on the implication of a 'real infinity', I would say no. There's no physical mass or energy that is 'infinite'. Conceptually, it helps to quantify mathematics on a scale larger than the calculations being done for materials but other than that, the idea of infinite is not a useful one. The only thing that appears to be infinite is time but time is also a construct that is humanistically designed to be infinite.
>>
No way to verify with our current technological/scientific knowledge.

There currently is no "infinite" thing we know of except for abstract constructs.

Infinity is a real 'concept' though, in the sense that we can "always add 1."

The Euler characteristic of a compact oriented surface is 2g-2, where g is the genus of the surface. Thus for the 2-torus, whose genus is clearly 1, we have that the Euler characteristic is 0. On the other hand, by definition, the Euler characteristic is also the alternating sum of the Betti numbers. The torus is being connected its zeroth Betti number is 1 and, by Poincaré duality, its second Betti number is 1 as well. It's also not hard to see that the fundamental group has two generators and is abelian and thus, by the Hurewitz theorem, the first Betti number of the torus is 2. Combining everything we get that 1-2+1=0 or, in other words, 1+1=2. QED

The meme occurs on page 379 of Volume I, of the three-volume work. About another 1600 pages follow.

At one point Whitehead and Russell had wanted to devote a fourth volume to geometry, but they were "intellectually exhausted" and never got round to it.

Hey /sci/, 20 year old anon here,

So for my entire life, I have lived with a severe Depersonalization disorder. I have memories as early as 5 of questioning if I am actually alive and what reality and noticing a strong visual snow effect across my visual field.

It wasn't until a couple years ago that I realized I needed to seek professional help with it. I ended up self medicating with cannabis (which paradoxically improves my condition acutely but has quite a few drawbacks), opioids, and occasionally psychadelics, about a year after i started seeing psychiatrists and psychologists.

I was continuously told that I was unlikely to ever find a solution, as my case was very resist mentioned to treatment and comorbid with depression and very bad anxiety, 3 brain surgeries over a 12 month period, as well as the previously mentioned substance abuse.

After a handful of doctors and over a couple dozen medications (ssris, ssris, tricyclics, maois, antipsychotics, anticonvulsants, benzos, anticholinergics), including the few things out there which are indicated for depersonalization (selegeline, xanax), I finally think I might be onto a solution.

About a year ago I began seeing a doctor that I told myself would be the last if things didn't work out. I was surprised that instead of being given whatever was left to try in the serotoninergic antidepressant classes (which never brought positive results besides totally numbing and flattening my emotions), he allowed me to make a case for what I thought was worth trying after extensive and almost obsessive research.

Fast forward to today. I'm currently on 225mg pregabalin, 300mg armodafinil, 20-40mg baclofen, 4mg tiagabine, and 25mg hydroxyzine daily. I picked out each of these medications besides the hydroxyzine.

Cont

I've been on all but the armodafinil (started 1.5 months ago) and the tiagabine (started 2 weeks ago) for about 6-9 months.

The pregabalin and baclofen did provide more benefit than anything I've tried up until that point, but the tiagabine was the diamond in the rough that had to this day been more beneficial and less harmful than anything I've been prescribed to this date, and this is only after a couple weeks of treatment.

The past week alone has been the most "normal" I've felt since before I started seeing doctors. I guess the stigma of being broken and unfixable attributed to that.

First and foremost, I know that I'm still early on in the tiagabine treatment, but I'm wondering if the addition of a GAT inhibiting drug like vigabatrin or valproate could lead to an even larger reduction of my symptoms if I replaced the pregabalin and/or baclofen with something like that. Vigabatrin is out of the picture due to cost.

But could the specific combination of medications be the key here?

Furthermore, I'm almost baffled by the lack of data on tiagabine out there. There's none research or even anecdotal data about it being used for depersonalization, and the data that is out there is quite limited.

Seeing how much of a difference I've noticed makes me wonder if tiagabine (or the combination with other medications) could be an unstudied solution to treatment resistant depersonalization. I understand from personal experience and from reading anecdotal reports that the resistance to everything you throw at the problem can be almost scarier and more disturbing than the original problem.

The thought that this could lead to helping so many people who've been in the same position as me has convinced me to ask around and see if there's any evidence here or if I'm just lucky.

Let me know your thoughts, I have a feeling that I might have caught on to something almost by chance.

Pic unrelated of course.

In a circunference of any radius, two particles start from the same point at the same time and start moving at the same constant speed. One goes through the diameter of the circunference, whipping back once it reaches the end, and the other one follows the line of the circunference. Why will they never meet?

>>8790922
Pi is irrational, so the relation between the distances travelled by both particles can not be expressed as a fraction (ratio). Therefore there is no combination of integer numbers of revolutions and straight travels.
>>
>>8790922
Let the diameter = 1, wlog. No multiple of pi can ever be an integer, (if it could, pi would be rational) and the distance travelled by the diameter-bound particle will always be integer valued at the edge of the circle

I believe that for each real epsilon > 0, there's a time t for which the distance between the particles is inferior to that epsilon.
I don't know how to prove it because my math is a bit rusty so if someone a little clever than me could post a proof...

What is on the forefront of reversing the aging process?

I'm personally think "reversing aging" means science having the ability to keep a human body in peak condition akin to your 20s for as long as possible, but feel free to educate me on a technical meaning if there is one.

What I've basically got from some articles and videos that suggest clues to slowing aging:

-telomeres and finding that the shorter they are in cells, the closer the cell is to biological death

-caloric restriction is speculated to slow aging, 30% caloric deficits and Intermittent Fasting looked at

-hormones and their speculated effects on aging, HGH, DHEA, Test, etc

This subject is fascinating to me because I love the idea of a human body being in its physical prime for as long as possible without all the deteriorating events that come after your thirties.

if you want to have a shot at immortality make good life choices. dont smoke, dont drink. have balanced diet, stay lean. exercise to maintain muscle mass, mobility and cardiovascular fitness. keep your brain working.
other things you can do - become molecular biologist to work on therapies killing senescent cells or fixing other damage caused by aging or donate to people doing it

So I'm a Social Studies Student (or it's my Major or w/eI'm Irish IDFK) and I'm super fascanated by Freuds stuff. Not his wordin (boy was obsessed with sex) but the whole thin behind his theories, especially collective consious. Is anyone else as obsessed as I am? We only looked at his theories on the ID, Ego & Superego, The levels of consiousness and his development theory but there's gotta be more I am so on board with them desu
