Modern Solism

21 more posts in this thread. [Missing image file: 1364839892399.png]
I'd like to introduce Modern Solism to /sci/, as it seems like something many of you could get behind. Modern Solism is a new, non-theistic philosophy/religious movement; none of us consider the Sun to be a 'true' god, but it has done all that a god is said to do, even if it is an inanimate object -- it has created life as we know it, provides food for us and all of the planet, and it's the only thing we could say watches over us constantly. For the significant role it has had in our creation and our reliance upon it for our survival for all of our existence, the Sun is something deserving of our veneration, Modern Solists conclude. We place the Sun as an object at the centre of a set of ideas which present an alternative to the choice of faith in the unverifiable or the concession of nihilism. Modern Solism is all about affirming human identity and encouraging people to work to preserve our species and nature; two of the greatest creations of the Sun. Feel free to come in and discuss, critique, or ask questions. SOL OMNIBUS LUCET

Is it possible to calculate the entropy of an irrational number? Specifically, Pi. I'm wondering because a friend of mine stated "because Pi is infinite, every single sequence of numbers should occur within it eventually, every movie, game, etc", but I think claiming Pi has infinite entropy is somewhat dubious. In fact I really don't see it being true at all, because their are irrational numbers with very low entropy, what would make Pi the exception?

Why aren't scientists respected in society? We do so much for them, yet they laugh at us and just see us as losers who can't get a real gf.

When a resistor is connected by itself to an ac generator, the average power delivered to the resistor is 1.02 W. When a capacitor is added in series with the resistor, the power delivered is 0.659 W. When an inductor is added in series with the resistor (without the capacitor), the power delivered is 0.340 W. Determine the power dissipated when both the capacitor and the inductor are added in series with the resistor. Note: The ac current and voltage are rms values and power is an average value unless indicated otherwise. Pic related. Can someone give me the answer to this? If asking for help on homework problems is against the rules, apologies. I'll delete this. I'm just way over my head with physics. Not a strong point of mine.

Hello /sci/, I'm having a problem and I was wondering if someone could help explain it to me. The problem is as follows: At a certain college, the housing office has decided to appoint, for each floor , one male and one female residential advisor. How many different pairs of advisors can be selected for a seven-story building from 12 male candidates and 15 female candidates? I've calculated it for one floor using the nCr formula. I just don't know how to implement it for the 7 floors. Any help would be much appreciated.

Evolution

Hey /sci/entists, do you know some good documentaries about evolution? I'm already searching for months, but so far I only found mediocre stuff made by atheist fanatics and attention whores on Youtube. That didn't help me much. Please help!

Hey /sci/entists! There are probably a lot of people here interested in computer science and electronics. We're asking at /q/ to make the /cs/ board happen, a board for electronics, computer science and programming If you're interested, please, join us! >>>/q/520502 >>>/q/520504 We'll create a dialy we want /cs/ thread at /q/

Physics Biot-Savarts Law

0 more posts in this thread. [Missing image file: h14_threewires.png]
Anyone know how to solve this? Three infinite straight wires are fixed in place and aligned parallel to the z-axis as shown. The wire at (x,y) = (-11.5 cm, 0) carries current I1 = 2.3 A in the negative z-direction. The wire at (x,y) = (11.5 cm, 0) carries current I2 = 1.1 A in the positive z-direction. The wire at (x,y) = (0, 19.9 cm) carries current I3 = 5.8 A in the positive z-direction. What is Fx(1), the x-component of the force exerted on a one meter length of the wire carrying current I1? What is Fy(1), the y-component of the force exerted on a one meter length of the wire carrying current I1?

Why is there only one zero but every other number has a pair or even a triplet? Was there any research done on the usefulness of -0 and +0 (in pure mathematical terms - not with binary)?

Hey /sci/. I can't for the life of me find secondary data for the potential dividers of changing the the resistance of R1 and how it it affects the output voltage. Anyone got any decent sources I could use?

I don't know much about this sort of thing, but I'm pretty sure this is not how relativity works. Can someone explain it to me? Also, to summarize: in the show they're flying out toward Jupiter, so he says one minute for them there will be three months on Earth, and when they come back, six months have already passed, despite them only being out there for an hour.

Justification Vs. Knowledge

0 more posts in this thread. [Missing image file: Epistemology.png]
There is no doubt how we got here as humans in the 21st century is in part due to the phenomenon of justification. Examples of justification: >Wagering on a random horse to win, and it does. >Religious prayer before scientists in the '50s discovered the placebo effect. Somewhat related due to the fact science considers justification invalid due to lack of empirical evidence

Medical Science? Optometry to be specific? I don't know if this is the right place to be asking but I'll give it a shot. Last Thursday I got sick with flu-like symptoms, cough, sneeze, runny nose, fatigue, sore throat, aches all over, fever, headache. The thing that stood out though was the headaches, it wasnt constant but it was the worst i have ever felt in my whole life, it would go away for a few minutes and then suddenly feel like i got whacked in the back of the head with a 2x4, this sharp pain also happened every single time I coughed. Friday was brutal, couldn't function at work, left early. Saturday all other symptoms were receding but the headaches remained. Sunday I realized something was wrong with my vision, i seemed to be getting a constant afterimage as if I had looked at a very bright camera flash but the pattern was totally different for each eye. Today I was functional enough to work, symptoms are nearly gone including the headaches and the afterimage effect has shrunken but is still there, I am hoping it will recede further until it goes away but it's like nothing ive ever experienced. Anyone seen or heard of such a thing before? Pic related, scaled about 200%, if each field was entire field of visions than patches would be half size, they seem green when seeing and invert to pink with eyes closed.

I have a question /sci/. If I were to be close to the centre of a large gravitational point, such as a star, and then I shon a beam of light to you, who was in a position where spacetime wasn't distorted, would you not see me shine the beam of light slower and in theory light itself is slowed down? Just a simple question that's been bugging me the past few days.
