| Posted: 27 Dec 2016 10:37 PM PST As an Electronic engineering student, I've almost never got a perfect straight line while plotting a V/I graph even under lab conditions. [link] [comments]  |
| Is there any association between left-to-right languages and right hand dominance, and vice versa? Posted: 27 Dec 2016 07:15 PM PST Maybe not anymore, but was there ever any evidence that languages that were created and written right-to-left were done so by primary left handed people?

| Ask Anything Wednesday - Biology, Chemistry, Neuroscience, Medicine, Psychology Posted: 28 Dec 2016 07:05 AM PST Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Biology, Chemistry, Neuroscience, Medicine, Psychology Do you have a question within these topics you weren't sure was worth submitting? Is something a bit too speculative for a typical /r/AskScience post? No question is too big or small for AAW. In this thread you can ask any science-related question! Things like: "What would happen if...", "How will the future...", "If all the rules for 'X' were different...", "Why does my...". Asking Questions: Please post your question as a top-level response to this, and our team of panellists will be here to answer and discuss your questions. The other topic areas will appear in future Ask Anything Wednesdays, so if you have other questions not covered by this weeks theme please either hold on to it until those topics come around, or go and post over in our sister subreddit /r/AskScienceDiscussion , where every day is Ask Anything Wednesday! Off-theme questions in this post will be removed to try and keep the thread a manageable size for both our readers and panellists. Answering Questions: Please only answer a posted question if you are an expert in the field. The full guidelines for posting responses in AskScience can be found here. In short, this is a moderated subreddit, and responses which do not meet our quality guidelines will be removed. Remember, peer reviewed sources are always appreciated, and anecdotes are absolutely not appropriate. In general if your answer begins with 'I think', or 'I've heard', then it's not suitable for /r/AskScience. If you would like to become a member of the AskScience panel, please refer to the information provided here. Past AskAnythingWednesday posts can be found here. Ask away! [link] [comments]  |

| Are fruits of today the same as fruits of the past? Posted: 27 Dec 2016 06:06 PM PST Do plants under go genetic mutation like humans? And if so is it possible that a banana of 100 years ago was different then the banana of today? [link] [comments]  |
| Posted: 27 Dec 2016 05:58 PM PST So how can take open their months and actually swallow?
Is the 1st stomach so powerful that it can resist all that pressure? What about the organs that lead to the stomach then? Thx for any answers! [link] [comments]  |
| Why do canopies (parachutes and paragliders) use the opposite input of airplanes in order to turn? Posted: 28 Dec 2016 05:41 AM PST When flying a ram-air canopy, the kind that modern parachutists use (skydivers, BASE jumpers, paragliders, speedfliers), a right turn is made by pulling the right trailing edge down. This effectively makes the wing slower on one side, and a turn is made towards the slow side. There can be considerable bank angles when doing this, sometimes over 90º. When an airplanes turns to the right, the left aileron lowers, making the left wing stronger/ slower, and the lift created from a stronger wing pulls the left wing up, banking the plane to the right. Why is it that parachutes and airplanes do the opposite in order to achieve the same? I have already ruled out gravity vs. engine, because airplanes can turn with their engines off, as long as they have airspeed. [link] [comments]  |

| How to convert from Jansky to determine a source's true intensity? Posted: 27 Dec 2016 05:16 PM PST I have seen a lot of flux measurements of masers in the literature be made in Jansky which has units of W/(m2 Hz). To convert this to the more familiar unit of watts and determine a source's emission intensity, is it fine to simply multiply the flux by the surface area of the observing radio telescope (e.g. Parkes Radio Telescope, nearly 4000 m2 ), and then integrate this over the frequencies measured based on the signal's spectrum? Or is this approach incorrect? [link] [comments]  |
| How many lux is the average computer screen? Posted: 27 Dec 2016 02:56 PM PST I recently got a 10000 Lux happylight to fight off seasonal affective depression. I'm wondering how bright my computer screen would be compared to the light, and for the life of me I can't find anywhere on google that gives the Lux of a computer screen. [link] [comments]  |

| How is the magnetic quantum number limited by the schrodinger wave equation? Posted: 27 Dec 2016 12:11 PM PST If someone can break it down for me and help me understand in more basic terms that would be great! [link] [comments]  |
| What's the fastest a production car can accelerate and still be safe for the driver? Posted: 27 Dec 2016 08:40 PM PST The Tesla P100D is the fastest accelerating production car with 0-60mph in 2.5 seconds. Which got me wondering, how far could they go? Can we eventually each a limit where it won't be safe enough? Or not possible to go any faster due to tire friction and other variables? [link] [comments]  |

| How is an optimal minimum wage calculated? Posted: 27 Dec 2016 12:23 PM PST Economists seem to agree that raising the minimum wage would be beneficial across the board. But obviously it cannot be raised arbitrarily. You can't just say everybody makes at least $100/hr now. So it seems like we're looking at an optimization problem. What factors actually go into this calculation? [link] [comments]  |
