Why would I willingly step into a transporter knowing this? The me in the now would cease to exist.
Particles fly straight. Waves don't.
Photons don't fly straight. Photons aren't a particle.
Light is a wave.
Our instruments to measure the information in waves are ill equipped. There is obviously some kind of random element messing up the experiment that makes it appear to be a particle.
I can't believe those documentaries had me believing a bunch of bullshit about simultaneous dimensions that do not exist.
a) a fairly successful mathematician published a crank theory that he refuses to admit is wrong;
b) a Fields medalist failed to grasp his theory by not understanding the difference between 'or' and 'and'?

>OSAKA--Scientists here have created a biodegradable paper-thin sensor device that connects to the internet of things (IoT) system to transmit data.
The nanopaper sensor device, which the researchers developed to collect data without damaging nature, is a potentially large leap toward production of environmentally friendly electronics.
The devices are expected to be adopted for data collection without harming the environment in places where instruments would be difficult to recover.
The substrate and some other components of the devices are made of nanopaper comprised of extremely thin fibers, allowing the device to be decomposed by microorganisms in the soil.
Commonly used substrates in electric appliances are non-degradable plastic, which are harmful to the environment if they are not recovered after use.
Takaaki Kasuga, a doctoral course researcher at the ISIR, and his colleagues created a hygrometer, which measures humidity in farm soil, by placing a coil, transistor and other parts on the nanopaper substrate.
The biodegradable nanopaper fibers is one-1,000th as thin as fibers in regular pulp paper. The sheet's surface is smooth, resembling plastic, making it a good substitute for the material.
In about 40 days, 95 percent of the total volume of the device had decomposed into the soil, the researchers said. Its metal parts also rusted.
I'm retarded and this is the worst part of heart disease. Always assumed it was reversible.
No longer theoretical, it is demonstrably practical.
That being said, it is virtually guaranteed that this will not have any positive impact on medicine in our lifetimes.
Why is it that obviously promising if not guaranteed science rarely sees the light? What is the main contributor between a lack of funding, a lack of skilled professionals, or pesky legal restrictions?
Groundrules: you cannot use the money for anything personal, all expenses will be for lab/equipment. You will receive 100k salary for your personal expenses per year during the lifetime of the project to lead and manage the project. A gym and a full kitchen with staff will be allowed expenses for the project team members.
What is your proposal?
I don't even need it for my career path but it seems like a more relaxed challenge and also I'm flirting with the idea of changing my career path towards something more chemistry-biology oriented (currently in pure maths but had some trouble with calculus 1 and physics 1 in the past year, I guess I must be a brainlet but gen chem and gen biology were comfy so I want to give it a try)
Already learning the basics of organic chem at it doesn't seem so difficult - of course I was warned that it's not that easy to get used to it but I'm getting familiar with some nomenclature laws and terminology before starting the course to win some time.
Was anyone else in this situation? (in the middle of uni but having dilemmas between changing your career path because you realized you're more interested in something else or stick with the thing you chose years ago in HS just to avoid potentially wasting time)
As I'm barely starting and I've discovered that my mathematical skills are absolute shit not much would be lost desu

However, wouldn't it be nice if people don't have to feel hunger, loneliness and pain, have enhanced short and long term memory, reduced aging effects, increased long term health and enhanced immune system, less prone to depression and other mental illnesses, etc? Why aren't there more funding for genetic manipulation research that is specifically targeted towards humans?
Describe in your best words how they work, why they work like they do, what the process is both specifically and in relation to circuits and the environment and why they are the complete denial of the other.

>Martian soil is toxic, due to relatively high concentrations of perchlorate compounds containing chlorine. Elemental chlorine was first discovered during localised investigations by Mars rover Sojourner, and has been confirmed by Spirit, Opportunity and Curiosity. The Mars Odyssey orbiter has also detected perchlorates across the surface of the planet.
What are potential issues with the 3 laws?
How would you modify them to correct these issues? Would you propose a different set of laws altogether?
Im wondering if adding/modifying the 0th law to be "A robot may not interfere with the development of the human race, or through inaction, allow other non-human entities to do the same" would be a good idea?
The issue is that the 3 laws eventually lead us to a pointless existence. We do what the robots want us to do, even without realizing it. Its not a bad existence, because they will always have our best interests in mind, but it would be a stagnant one. We would lose what it means to be human. The idea with this is to prevent robots from deliberately trying to impact our long term development, even if that means that it leads to a less than optimal future. On the other hand, if something other than a human is going to severely alter our destiny like a cataclismic meteor or an alien invasion, they would still take action to prevent this. Then again, what if we WANT to contact aliens? I guess if we approve of the contact, then it would not qualify as allowing a non-human entity to influence us, since it would be a mutual agreement.
Thoughts? other ideas?
There's this tv show I watch all the time that I love, and I think about it a lot. When I'm eating breakfast or lunch I'll randomly think about one of the episodes. The thing is, almost every time this happens, that episode will come on TV either that day or the next. It isn't just a once-in-awhile thing, it happens like 3 times a week and has been like this for probably close to a year. This used to happen to me about 10 or so years ago with other shows I watched. Every time I would think of an episode, it would soon be on.
I don't know how to word this thread without /sci/ giving me crap, but what do you think is going on? Has anything like this happened to you? Do you think the brain can have intuition/psychic abilities/etc.? I know there's a guy named Rupert Sheldrake who talks about morphic resonance.

My plan to this point is, that I'll show them the complex plane and show them an example for an addition and subtraction. Then I'll tell them how it is possible to calculate it without the plane.
Is there anything I could add except from that all numbers are in fact complex but have an imaginary part of 0?
is that realistic?

I graduated from university last spring and decided not to pursue grad school even though I had spent the last two and a half years working in one of my professor's lab. I even got a co-author on a paper that received a distinguished award.
I got a job a few months after graduating and am still there. It's pretty comfy but I don't feel at all challenged. I'm strongly considering applying for some programs for next school year but am unsure if it's too late for me?
Anyone have a similar experience and ended up going for it anyway?

The first question you must present to yourself is whether or not your mind has the complexity necessary to temporarily forego the sense of agency that accompanies free and unrestricted thought such that you can overcome that experience at a later moment and restore natural autonomy without lasting damage to your psyche. It is not necessary to forego your own philosophy entirely, but merely to move it out of the way such that any parts of it that are currently wrong will not become terminal obstacles to further communication.
I have yet to verbalize the inner constructs that have led to my current beliefs. If you are interested in my thoughts then I ask that you exercise patience in understanding that they are not formalized in a linguistic capacity. Such a method of formalization would necessarily be incompatible with generalized hyperconceptuals.

The solutions to these questions can be computed with relative accuracy, and I think that's exciting. What is it about the structure of a question that affects speed and accuracy at which the solution can be reached by a computer? Where should I focus if I wish to study this kind of thing in depth? Linguistics? Theory of computation? Is there a Lang-tier text on this subject? I adore Lang's pedagogical style of his algebra text, and I really want to study this stuff in depth. I'm not a uni student but mathematics was my favorite hobby before it became my dedicated obsession.

as a white hetero cis-male, i have no idea what to do here. i'd be happy to sign up but does that even make sense? i get the impression that the idea is for the program to just be for women and minorities and to a lesser extent non hetero/cis people.
i unironically support more women in stem and so forth (honestly i feel like my field, physics, is stagnant because of nature right now, not because of the people working on it, so if i get to work with more girls instead of all dudes that's fine and no great loss to our stagnant field) and minorities and gays/lesbos/trannies/queerfags are fine too. and i'm OK with them starting their little clubs for them. but when they invite me to clubs they start and act like i'm totally welcome i'm like "wot?".... just does not compute. i figure it is just a token motion to say "everyone is welcome" when really they mean "all non-cis-hetero-white-males are welcome"
Some studies say that people of both sexes had higher testosterone levels than modern ones.
Also when we look at laws of ancient people, we can guess that everyone seemed to be more dominant, aggressive and dogmatic.
Is there any study about this?
What the fuck bros
I was thinking about this. Antidepressants definitely make people happier, sure. But do they increase the survival chances of one's genes, or do they maybe decrease them? I've had friends whose parents took antidepressants, and the kids ended up depressed, lost, questioning reality, probably because they didn't have strong moral guidance as children, because their parents were drugged up zombies (and yes these drugs do turn you into a zombie, I know from experience).
Remember that the only outcome that scientists will be checking for is "happiness", or your "functioning" in society. They don't give a fuck whether you spread your genes or not. But YOUR priority IS to spread your genes (that's the priority for every organism on the planet).
Think about a criminal, someone like El Chapo, the Mexican drug lord. He didn't "function" in society, because he went outside of the bounds of society's laws. He ended up having a lot of children, between 11 and 15 according to different websites. So he definitely did fulfil his priority of spreading his genes.
>TLDR
Maybe antidepressants aren't actually in the patient's interest. The health systems loves them because they turn you into a "functioning" member of society (you work a job, you pay taxes, you're generating money for the government, and you'll be generating profits for Walmart when you do your weekly shopping, etc.). Maybe antidepressants are pushed because they're in SOCIETY'S interest, not yours.
That is, perhaps antidepressants are a tool of exploitation. What do you think, /sci/?

Ok, here's how I am understanding my problem;
You have two tree's, an apple tree and an orange tree. The Apple tree has produced 60% of max fruit, the Orange tree has produced 40% of max fruit. Sunlight today makes the Orange tree produce 25% LESS fruit at some indeterminate time in the future, and sunlight today makes the Apple tree produce 25% MORE fruit at some indeterminate point in the future (IDPF) , but sunlight today decreases humidity by 10% at IDPF. Humidity today makes the orange tree produce 30% MORE fruit at some IDPF, where as humidity today makes the apple tree produce 75% MORE fruit at some IDPF, and humidity today causes 20% more sunlight at IDPF.
So, that's the problem as much as I can rationalize it. Now I'm not sure how to set this up into an equation to accurately evaluate this statement is the problem. For example, to highlight the variables let's say the Orange tree is producing 20% fruit now, Apple tree 50%, sunlight is at 40%, and humidity is at 70%. Is there a way to find what sunlight and humidity would have been at during an indeterminate period in the past to the tree's current yield? What is the expected yield of the trees at the indeterminate time in the future? How do I properly equate all of these variables, if I know everything except the humidity can I properly evaluate the equation to find humidity? What will the ratio of apples to oranges be in that scenario?
The actual problem is that I'm trying to equate three pieces of data to each other; the performance of GDP, which effects investment and The cycle. The business cycle itself, which effects GDP and investments. And Investments, which is just affected by GDP and Cycle but effects nothing.
