Is there any physicist that publishing works related to philosophy? Becasu as far as i can see, usually it's opposite.

On pic related, let's assume that the curve above the line is an arc from a circle, and the line is not its diameter, but a random line cutting the arc. And let us assume that h is perpendicular to the line L starts from the middle of the L, and ends at the highest point of the curve.

can somebody solve this?

sup /sci/, this board is as close to spirituality as it gets on 4chan So I read a book about Tao Yoga and started practicing 3 days ago. I already opened the Small Heavenly Cycle also referred to as the Microcosmic Orbit. Opening the Orbit and thus opening the 13 chakras in my upper body and head was quite an experience I have to say. So some of the more advanved things got me really curiorus. In this book the author refers to the Seven Formulas of the Seven Books of the Tao. Those being: 1) Fusion of the Five Elements 2) Lesser Enlightenment of Kan and Li 3) Greater Enlightenment of Kan and Li 4) Greatest Enlightenment of Kan and Li 5) Sealing of the Five Sense Organs 6) Congress of Heaven and Earth Immortality 7) Reunion of Heaven and Man. True Immortal Man. Most of these stages are reserved for those who practice everyday for hours 30 years straight - and you can have a talent for this, so if you're dumb in that way you'll never reach those levels. As I said I completed the Microcosmic Orbit in a day, this includes opening 13 chakras. On average however it takes a person 2 - 4 weeks to even feel anything in the first chakra, that is, the navel. If there is any merit to this Tao Yoga Chi thing, shouldn't there be people who are True Immortal Men? The book says at that stage your white hair will become black again, and your skin and your organs will rejuvenate. Also the higher your level the less will you feel the need to eat, as you draw your energy from the sunlight. Intuitively this all makes sense, kinda. Is it possible?

I'm self teaching myself a module (probability theory) before the next term starts from a textbook. However I'm finding that it's taking an absurdly long time. It takes me about 2-3 hours to process 12 pages. Is this normal? Am I being inefficient? The reason I'm doing this, other than to learn a prerequisite module, is that I often don't fully grasp the subject just by attending lectures (I also skip a lot of lectures ...) so I need to find another way to learn the material. My method is to read through a "sub-chapter", write down any key points in rough, write down any questions I have, try and answer them on my own, draw diagrams etc in order to help me paint a picture of what's going on. I do the example questions as they come up, first trying them on my own then looking at the answer for a hint until I understand how to process the problem, note what was the key to the solution and then I go back and summarize everything in my own words neatly. How do you work through a textbook/teach yourself something?

detonations and materials around it.

i asked this question on /k/ but they don't seem to have the knowledge. i understand that with flagration materials that just reacted get pushed away from the flame front mostly in the form of gas, that's as easy as anything. with detonation however materials move with the reaction front forwards. my question is: do materials surrounding the explosive get pulled in and move in the same direction too?

is dark matter confirmed to exist or is it only made up because some shit couldn't be explained otherwise?

I'm starting to hate math and I'm an engineering major? Should i just power through? How do you guys deal with falling out of love with your major? What are some majors that aren't shit and don't involve high level calculus?

>A new study of Chinese-Caucasian, Filipino-Caucasian, Japanese-Caucasian and Vietnamese-Caucasian individuals concludes that biracial Asian Americans are twice as likely as monoracial Asian Americans to be diagnosed with a psychological disorder. Whereas the figure for Japanese mixes is just above average, Chinese-White mixes are three times as likely to have mental health/development issues http://www.news.ucdavis.edu/search/news_detail.lasso?id=8732

>your face when you finally learned how the standard model lagrangian density is actually implemented in practice you would think those graduate student fuckfaces could have just typed that shit out in plain english on wikipedia to explain it to people with a comparatively advanced, but not-quite-PHD level theoretical HEP, education

Did anyone here do really well as a STEM major in university? Right now I'm in engineering and having a problem with my exams. I put so much time into studying but when exams come I'm so shaky and get disorganized cause I try to rush or write before I think about it and end up erasing it or having it be wrong and in the end I just lose a bunch of marks on stuff I studied. Does anyone here have any chem/phys/math tips for exams to be 100% prepared? I get near 100% on all the non exam evaluation, but when exams come my anxiety just destroys me and i fucking spaghetti everywhere

I know when someone close to me is going to die. Can it be that I am the cause of that? Like for instance we live in a many-mind interpretation universe, and our consciousnesses is in a quantum like state in where I'm at different locations (worlds/situations) and it collapses into one when the measurement is made. Or maybe in a higher dimension where time isn't linear and past, present and future is at the same place, somehow we sometimes can tap into it. I don't have clue but this stuff keeps me occupied these last couple of weeks. Truth or not, theorizing about stuff like this, questioning reality in how we perceive it is pretty interesting to me. My own personal opinion is that it could all be a coincidence, because there are like 7 billion people on the planet. But it still makes me wonder because I was right on 5 different occasions. I would really appreciate your opinions on this matter, especially if your into quantum mechanic and string theory. Sorry for being vague, for English is not my first language. Just ask and I'll elaborate

Is there a computationally efficient method of finding the great circle distance? What about for a hypercube?

Is icing a wound doing more harm than good? The inflammatory response is annoying and sometimes painful but it allows for immune cells to reach the infected area and fight off any bacteria. So if you ice the wound the surrounding cells will constrict and fewer immune system cells will be able to help right? Or does is not make a difference?

Is overpopulation a problem?

Hey /sci/, So I'm reading this: >Limits to Growth was right. New research shows we're nearing collapse >Four decades after the book was published, Limit to Growth’s forecasts have been vindicated by new Australian research. Expect the early stages of global collapse to start appearing soon http://www.theguardian.com/commentisfree/2014/sep/02/limits-to-growth-was-right-new-research-shows-were-nearing-collapse?CMP=fb_gu And this stuff is f'n scary. Some quotes: >Research from the University of Melbourne has found the book’s forecasts are accurate, 40 years on. If we continue to track in line with the book’s scenario, expect the early stages of global collapse to start appearing soon. >The issue of peak oil is critical. Many independent researchers conclude that “easy” conventional oil production has already peaked. Even the conservative International Energy Agency has warned about peak oil. >Peak oil could be the catalyst for global collapse. Some see new fossil fuel sources like shale oil, tar sands and coal seam gas as saviours, but the issue is how fast these resources can be extracted, for how long, and at what cost. If they soak up too much capital to extract the fallout would be widespread. >As Limits to Growth concluded in 1972: >If the present growth trends in world population, industrialisation, pollution, food production, and resource depletion continue unchanged, the limits to growth on this planet will be reached sometime within the next one hundred years. The most probable result will be a rather sudden and uncontrollable decline in both population and industrial capacity. WOW! So… a rapid decline in population is coming. How many billions of people do you think will die?
