Is the Unit Circle and the Complex Plane related at all? Posted: 28 Oct 2017 06:55 AM PDT When learning trigonometry, the idea of the unit circle was the main mechanism to describe the effects of angles and the sine and cosine functions. Now that I'm learning about Q.M. and Euler's formula, etc, it's pretty evident that the imaginary plane and trigonometric functions are intertwined. How did these two sort of distinct ways to look at trigonometric functions (I.e the unit circle vs complex plane) come to be? Did one come from the other, or are they related? Is there a reason euler's formula and complex relations baren't taught in tandem with trigonometry? Thanks in advance! submitted by /u/throwaway3141598 [link] [comments]

How exactly were the first forged iron tools/weapons made without iron tools like hammers, anvils, tongs, etc.? Posted: 27 Oct 2017 08:07 PM PDT This question is inspired by the recent primitive technology video showing the building of a natural draft furnace: https://www.youtube.com/watch?v=u7wAJTGl2gc It got me thinking on a quandary: you need iron tools to make iron tools (and by this I mean, you need a very good and strong iron hammer to hammer away impurities in molten/hot iron and to shape it you need tongs and an anvil to hammer against. so how did the first people to break this chicken and egg problem do it? Did they use stone tools? thanks! submitted by /u/lingben [link] [comments]

Did scientists in the 19th century really think that the sun and other stars reflected light from another source? Posted: 28 Oct 2017 06:53 AM PDT In Thomas Dick's Celestial Scenery (1838 - 1848 editions) he states in the introduction, referring to stars: Do they shine with borrowed light, or with their own native lustre? and later in his 1869 edition of The Christian Philosopher he says The immense distance at which the nearest stars are known to be pplaced proves that they are bodies of a prodigious size, not inferior to our own sun, and that they shine not by reflected rays, but by their own native light. suggesting that at some point between 1848 and 1869 the idea that the sun and other stars might be reflecting light was shown to be incorrect. Was this something that scientists in the 1800's thought might be how the sun generated its light or was this an aberration of christian scientists like T. Dick? submitted by /u/hasbrochem [link] [comments]

Recent advances in Navier-Stokes equations? Posted: 27 Oct 2017 04:20 PM PDT Hi all, I'm just wondering if anyone knew of any current research that's looking into exact solutions to the full Navier-Stokes equations? Also, has any progress been made on solving the full NS equations at all?

Can nuclear power still be achievable without uranium? Posted: 27 Oct 2017 02:10 PM PDT I'm sorry if this is a bad question but I've recently been looking into nuclear power energy and it seems very efficient but the problem is that uranium isn't the safest element of them all. From what I've read, the reason uranium is used is that it's the easiest element to undergo nuclear fission (the splitting of atoms). My question is can we use another element that, like uranium is easy to undergo nuclear fission but unlike uranium is fairly safe (meaning a potential nuclear meltdown that won't spread radiation)? If so, why haven't we tried it? submitted by /u/Execute-Order-66 [link] [comments]

Travel Between Earth and Sun-Earth Lagrange Points 4 and 5: energy requirements? Posted: 27 Oct 2017 11:28 PM PDT From Wikipedia: Earth trojan The orbits of any Earth trojans could make them less energetically costly to reach than the Moon, even though they will be hundreds of times more distant. Can somebody confirm for me whether or not this line from Wikipedia is correct? Also, what would be the most energy-efficient way for a spacecraft to travel from Earth to either of those two locations? If I remember correctly, there have been some spacecraft sent on heliocentric orbits, but I am not sure if any have gone specifically to Sun-Earth L4/L5. submitted by /u/DDRussian [link] [comments]

We say that the Universe is expanding. But what would be the difference in saying that we are actually compressing? Wouldn't that explain a lot of things that expansion does not? Posted: 27 Oct 2017 09:03 PM PDT I mean, it's a question of relation, isn't it? To me as a layman who loves space and science, it is obvious that somehow, in ways I do not understand or pretend to be able to express, whatever "we" are, fell into a black hole, and that the thing we are experiencing as expansion is in fact our polar perception of things shrinking as we close in on the event horizon. Wouldn't this explain, well, everything? It would explain heat death pretty neatly, wouldn't it? submitted by /u/tjackpundarn [link] [comments]

When a woman is pregnant, does the baby have a sense of direction? (For example, does the baby feel if the mother were to be lying down sideways as opposed to standing up straight) Posted: 27 Oct 2017 06:08 AM PDT I was having a conversation last night with my wife (who is 4 and half months pregnant) about baby movements in the stomach. I know that the baby can feel some of her movements and can definitely tell when she's moving around or not. But I was wondering if the baby can feel any sense of direction in the womb (if my wife was upside down vs. standing up straight, would the baby notice a difference?) submitted by /u/nayan742 [link] [comments]

Why is "maximum torque" a measurement of engines? Can't you get an arbitrary high torque by using a bigger gear difference? Posted: 26 Oct 2017 10:48 PM PDT By the "lever principle", increasing distance allows the same force to be applied with less power. If you had a really high difference between high and low gears (or use several sets of high/low gears to further multiply the difference), could you apply progressively more power to the wheels, achieving a higher torque (of course, at the price of moving slower)? submitted by /u/GeneReddit123 [link] [comments]

How much/does the caloric content of food change with cooking? Posted: 26 Oct 2017 10:07 AM PDT It seems like it should, since heat is involved, even if it might not be an appreciable amount (until you get to mass amounts of food). Bonus, does the type of cooking matter? Like, scrambled eggs vs hard boiled? submitted by /u/dragonflytype [link] [comments]

[Math] What is the size of a differential? Posted: 26 Oct 2017 06:21 PM PDT I've done differential and integral calculus, and the question is bugging me more and more. Something doesn't seem right to me, especially in integral calculus. The width of the Riemann Sums is dx, and dx was taught to me as "infinitely small". And to me, infinitely small is just 0. And summing 0's even for the time left in all universes won't do anything. What is wrong here? Are our minds ( or just mine -.- ) just too stupid to grasp the concept of differentials and infinity? What would be the decimal representation of a dx? Not 1, not 0.1 and clearly not 0. I feel as if I were playing with magic. Edit: I forgot how to write. submitted by /u/Zokalyx [link] [comments]

Why are alpha, beta and L and K iron spectral lines so important in understanding black holes? Is there any special information gained from analyzing these lines as opposed to any other?

What is the actual theoretical energy output of the ITER? Posted: 26 Oct 2017 11:25 AM PDT In their website they have mentioned the experimental reactor will produce 10 times the energy it is given.

While the vessels obviously don't make contact with the tunnel is there more pressure when they are traveling overhead? submitted by /u/Pineapllepusher [link] [comments]

Is there any possible relation between the imbalance of matter/anti-matter and cold spots on the cosmic background radiation? Posted: 26 Oct 2017 03:41 PM PDT This article about matter dominating over anti-matter combined with this article about the possibility of the cold spot being from bumping into another universe got me wondering.

Why are elements (like gold) found in chunks and concentrated in some locations? Posted: 25 Oct 2017 12:10 PM PDT Hi everyone, I'm no astronomy expert at all, therefore sorry if I say something too stupid here. :) As far as I know the elements are formed in the universe by fusion (up to iron) and other super events (like supernovas) for elements above iron. My doubt is, if atoms of an element (gold for example) are formed randomly in the universe, how come here on Earth they are always together in chunks (nuggets) and always in some specific locations (where they concentrate the mining)? I've learned that Star formations produce a gaseous proto-planetary disk around the young star. All this "dust" collide and stick together throughout the years, gradually growing to form planets. So, if this is the case, how come atoms from the same element come together? Do they attract each other? Is it due to they similar weight? Thank you all! submitted by /u/firefss [link] [comments]

How do ion propulsion systems avoid building up a huge static charge? Posted: 25 Oct 2017 03:37 PM PDT From what I understand, ion propulsion systems ionize a gas, typically xenon, then shoot it out at extreme speeds. And from what I understand of static electricity, when you have significantly more or less protons than electrons, you've got a static charge. If a satellite or space ship uses an ion propulsion system, which is stripping/adding electrons to the propellant as it is used, how are they avoiding an ever-increasing static charge as the vessel uses its engine? submitted by /u/mouseasw [link] [comments]

Do bigger people have more nerves than smaller people? If they have, do they have more brain capacity to complement it? Posted: 26 Oct 2017 05:39 AM PDT If people would have the same nerve density regardless of the amount of tissue, that would mean more sensory information from a bigger person's body. Would that at some point affect brain functions of really large people? And if you get fat, would that mean more nerves and information with the added skin and tissue? Your brain still stays the same. submitted by /u/TracesOfGuitar [link] [comments]

Does my current fitness level when conceiving a child affect my child in any way? Posted: 25 Oct 2017 07:04 PM PDT Like if I'm really fat when we conceive, does that make it more likely my child will be less healthy? Or vice versa if I'm very fit?

Is there a fundamental difference between tornadoes and dust devils, or is it *just* a matter of size?

Why is c (speed of light) the constant and not time or space? Posted: 25 Oct 2017 08:51 PM PDT If I orbit earth and fire a beam of light it should travel 300K km/s tangentially off the orbit. But if I take gravity into account then the light should bend to the gravity of the earth just as it does around a black hole. My question is why is it that light is the constant and time/space are the ones that bend.
