| What is the derivative of "f(x) = x!" ? Posted: 12 Dec 2016 04:15 AM PST so this occurred to me, when i was playing with graphs and this happened https://www.desmos.com/calculator/w5xjsmpeko Is there a derivative of the function which contains a factorial? f(x) = x! if not, which i don't think the answer would be. are there more functions of which the derivative is not possible, or we haven't came up with yet?

| Could someone explain the use of the different units utilized in radiation science? Posted: 11 Dec 2016 11:38 PM PST I'm so confused with all the units used for determining radiation. Can someone please explain to me what's the difference and the USE of the the units? I've been told to speak to patients in terms of BERTs... but then.... Grays, Siverts, Curies, Bequrels, Rads... etc... Is there also a difference when describing "generated" radiation (ie electron beam to a W target) vs natural? If I can't figure it out I'm going to be a completely shit clinician for my patients :( Why the hell can't we just have one set of units :( [link] [comments]  | ||||||||||||||

| What is "strangeness"? And how does it affect subatomic particles? Posted: 12 Dec 2016 05:26 AM PST I'm learning about leptons, baryons and mesons and some of them have a value called "strangeness", my teacher doesn't know what it is a measurement for and everyone gives me weird looks when I ask what strangeness is. My point is, some particles are charged, with that charge, they repel other particles with the same charge and attract particles with opposing charges, that's how charge affects particles. But how does strangeness affect particles? At the moment, it's just a meaningless, faceless value to me. :/ [link] [comments]  | ||||||||||||||

| Are face muscles controlled through the spine? Posted: 11 Dec 2016 07:04 PM PST I'm curious if the brain has to send signals through nerves in the spine to control face muscles, or if it can just go straight to the face because of the proximity. [link] [comments]  | ||||||||||||||
| Why is this silicone cover giving off dim light when warped? Posted: 11 Dec 2016 11:53 PM PST I recently bought an "object" covered in silicone, and while checking it for potential surface damage by warping it I noticed that it was giving off a very faint, but in low light conditions, rather apparent yet brief spurt of light. Now the object is battery powered and was on at the time of discovery, so I at first assumed it was defective and that the batteries inside were transferring electricity to the silicone and giving off a slight spurt of light, and I was therefore rather reluctant to use it for it's intended purpose, so I decided to remove the batteries for the time being. It has now been approximately been two days since I did this and any residual energy from the batteries should've disappeared, in case that was the culprit, but after checking again just now it's still happening and after a rather long time trying to phrase the question in a Google search I've found nothing. So I come here today asking, what do you think is giving off photons from this silicone? Is it a small amount of static electricity being generated by the friction of the silicone and the inner lining plastic surface of the battery compartment? Am I through touch transferring enough energy to the silicone and resulting in it manifesting beneath the surface as static electricity? [link] [comments]  | ||||||||||||||

| Is space continuous? And if is it then why do we have Planck Length? Posted: 11 Dec 2016 02:07 PM PST I have always wondered if space can be quantized or not. We have always been told that space is continuous. But if that is the case then why does Planck Length exist? [link] [comments]  | ||||||||||||||

| How does a computer go from assembly to machine code to doing things? Posted: 11 Dec 2016 04:23 PM PST I understand that assembly almost directly corresponds with machine code, but what steps are required after the machine code translation to do something such as adding a value to the register?

| How does a cryptographic attack know when it's succeeded? Posted: 11 Dec 2016 04:06 PM PST If you present a ciphertext to a computer program that was written to break the text's encryption, how would that program know it's made a successful attempt? In a primitive brute force attack, you might have millions/billions/whatever amount of possible keys to iterate through, each one producing some sort of "plaintext" once it operates on the ciphertext. How would the program know it's actually produced the plaintext on one of these iterations? [link] [comments]  | ||||||||||||||
| Posted: 12 Dec 2016 01:41 AM PST I've been looking data storage and I understand the principles of how data is stored on certain items like hard drives, SSDs, tapes, ect... but I'm curious as to how we discovered that these materials could store and hold data for long periods of time in the first place.

| Why when you hold something very close to your eye, does it have a kind of aura around it? Posted: 11 Dec 2016 02:21 PM PST When I hold my finger or phone right up to my eye, it has a blurry aura around it. What is it? Is it something to do with the human eye or the particles in the object? [link] [comments]  | ||||||||||||||
| How does a cell know what kind of cell it is? Posted: 11 Dec 2016 12:32 PM PST As I understand, the "job" of a cell is determined by which parts of the DNA are loosely packed and which parts are tightly packed. But how does this packing look like in stem cells and what happens when they differentiate? [link] [comments]  | ||||||||||||||

| Posted: 11 Dec 2016 11:27 PM PST The closest I could figure out by googling is that generator potential is triggered when cells are deformed. How are they different from Lamellar corpsucles, the mechanism of which was "easily" found by searching google for a few hours instead of asking the experts here? [link] [comments]  |
