| How do i calculate probability of a probability distribution? Posted: 01 Jun 2017 02:59 AM PDT Dear people. Hear me out. I have histogram of the probability of certain values x of a random experiment. Its looks very nicely like a normal distribution. Then I have the data of an experiment that I did that tells how many times I measured value x. I would like to find out how likely it is to find that specific value distribution of given the probability distribution that I have but I can't figure out how to calculate this. in other words, I would like to figure out how likely it is that my measured distribution is random or ordered. In analogy, I thow a dice 1000 times and I get the distribution of results. I want to figure out how likely it is that this distribution of numbers happened by random chance or not. Can you help me out? [link] [comments]  |

| Is there something to addition like what addition is to multiplication? Posted: 31 May 2017 11:27 PM PDT So multiplication is repeated addition 2*3=2+2+2. we know we can go further with Exponentiation being rpeated multiplication 23 = [;2\uparrow3;] = 2*2*2 and we can keep going like that [;2\uparrow\uparrow3;] = 32 = 222 [;2\uparrow\uparrow\uparrow3;] = [;2\uparrow\uparrow2\uparrow\uparrow2;] = [;2\uparrow\uparrow4;]=2222 etc. but can we go into the other direction? like 2+3 = [;2\downarrow2\downarrow2;] and [;2\downarrow3;] = [;2\downarrow\downarrow2\downarrow\downarrow2;] [link] [comments]  |

| What's the consensus on the executive function model of ADHD? Posted: 01 Jun 2017 07:59 AM PDT I'm an adult who was diagnosed with ADHD as a child (called ADD at the time). Thanks to the video that was on the front page a few days ago, I was recently introduced to the work of Dr. Russell Barkley. Much of what he said about ADHD being primarily an impairment of executive function sounded like it made a lot of sense, and it matched up very well with my own experience of my disability. Is this a well established theory of the cause and nature of ADHD? Is it well supported by the work of other researchers, or is Dr. Barkley on the fringe? If it goes against the consensus, then what is the consensus? Or what are competing theories? Here's a video that summarizes his ideas. [link] [comments]  |

| How do I calculate the probability of a frequency distribution Posted: 01 Jun 2017 03:09 AM PDT Dear people. I did an experiment that results in a frequency for a set of stochastic variables x. I also did a computation that predicts the distribution of the variable x given random chance (the probability distribution of x given randomness). Now I would like to know how likely it is that my experiment x is just random. Similar to throwing a dice 1000 times, counting the occurence of each eye and then calculating how likely it is that this dice is fair or that it is unfair. How does one do this? [link] [comments]  |

| How can a spectrometer split the light into its components? Posted: 31 May 2017 05:20 PM PDT I understand that faraway planets' atmospheres can be analysed because light refracts differently based on what the light is passing through, but I don't know how a spectrometer can determine how many and what kinds of light(-components) make up the light we receive down here.

| Is a tube more conductive than a solid wire? Posted: 31 May 2017 11:02 AM PDT To be more specific, does the greater surface area of a tube allow a greater flow of electrons than a wire with an equivalent outer diameter? If there is a difference, what is it and what are the applications? Edit: As pointed out by /u/undercoveryankee, the phrase "equivalent outer diameter" is potentially ambiguous. The intended expression was "same diameter". Ex: a pipe with 1mm OD compared to a solid wire with 1mm OD. [link] [comments]  |
| What is the origin of the anti-A & anti-B antibodies in Type O plasma? Posted: 31 May 2017 11:27 AM PDT A blood question that deserves a bloody answer! (Heh. Pun intended. Frustration also intended.) I have a BS in biology and was in a discussion with my coworker. I have type O+ blood and so does he. We're wondering if people like us with Type O blood are born with the anti-A and anti-B antibodies in our plasma or if we would have to be exposed to type A/B/AB in order to get these antibodies? Please support with reliable source if possible. [link] [comments]  |
| What is the law for the amount of momentum transferred in a collision of two elementary particles ? Posted: 31 May 2017 01:58 PM PDT Is there a law for the probability of transferring some amount of momentum between two ( lets say ) electrons, given some initial conditions ? Do they simply switch momenta or ( what i think ) is it random, depending on e.g. the angle ? What is the law ? [link] [comments]  |
| How does private key encryption work? Posted: 31 May 2017 01:39 PM PDT I understand the basic idea that you encrypt using your private key and their public key and they can decrypt using their private key and your public key, but if your public key is the inverse of your private key, how does your private key stay secret? can't people figure it out by just finding the inverse of your public key?
