| Posted: 02 Mar 2019 05:42 AM PST I know that where the anxiety comes from and how someone might work through it will differ between these two types of anxiety but I'm curious if they're functionally the same as far as the body is concerned. As an example: there is someone who has been violently mugged and they have developed severe PTSD due to it and then someone who has never been mugged but has extreme anxiety about getting mugged. Would there be any difference in the adrenaline/chemicals released by the body during a time of crisis for these two people? Also, would the type of medication, in general, be different for someone with PTSD verses extreme anxiety that doesn't stem from a traumatic event? I'm curious of the medication for PTSD is inherently different of its all just case by case basis depending on the situation and intensity. [link] [comments]  |

| What causes us to perceive someone's gaze as focused, vacant, or glazed over? Posted: 02 Mar 2019 12:44 AM PST I have seen time and time again, both in literature and in conversations with people I know, people describing someone's eyes. What I mean is that I have come across phrases like "Focused gaze", "Vacant gaze", "Fearful eyes", "Eyes lighting up", "Eyes glazed over",etc. What exactly is it that causes one to perceive another's gaze as focused, vacant, etc? Is it how often and how much the pupils contract? Is it the frequency of saccades? Is it something else? [link] [comments]  |

| When and why would someone choose to use Lagrangian instead of Newtonian mechanics and math? Posted: 02 Mar 2019 12:00 AM PST From what I understand, Lagrangian mechanics are a different way of formulating the laws of physics that Newton describes. I don't know all of Lagrange's equations yet, but looking around, the difference seems to be that he likes to describe things in terms of energy rather than force and he likes to use more derivatives in his equations.

| What is a right representation of the sun's path trough the sky? Posted: 02 Mar 2019 02:04 AM PST I have long been confused by the way the sun's path through the sky is visualised in many science textbooks. It's mostly visualised with a parallel path: http://blocs.mesvilaweb.cat/wp-content/uploads/sites/1648/2012/06/U3VuT25DZWxlc3RpYWxTcGhlcmU=_224517_1_5796_1.png But isn't a more accurate representation like this, where the path of the sun isn't parallel trough the year?: https://www.ecosoch.com/wp-content/uploads/2017/08/sun-path.png [link] [comments]  |
| why do we get pimples on our face and not like .. our legs? Posted: 01 Mar 2019 02:08 PM PST i know back/chest pimples are also quite common, but they still seem to concentrate mainly on the upper body. i'm under the impression that pimples are just infections so shouldnt they be able to appear anywhere?

| How do the oxygen atoms in hafnium dioxide (HfO2) have 4 bonds each in a stable lattice arrangement? Posted: 01 Mar 2019 06:50 PM PST https://en.wikipedia.org/wiki/Hafnium_dioxide I always understood that oxygen's most stable molecular arrangement requires each oxygen atom to have 2 bonds and 2 unbonded pairs of electrons? How can the HfO2 lattice as depicted in the wikipedia article be stable? Compare that to the wikipedia article for silicon dioxide, which depicts it as I would have expected: https://en.wikipedia.org/wiki/Silicon_dioxide. [link] [comments]  |
| Why are Galaxies a flat disk and not a sphere? Posted: 01 Mar 2019 02:43 PM PST Given there is a large mass (potentially a black) hole at the centre of the Galaxy, why wouldn't it attract stars and other mass from all directions and be shape of a sphere? Most pictures of Galaxies show a flat spiral shape! [link] [comments]  |
| Why do we consider Neanderthals and Homo Sapiens different species? Posted: 01 Mar 2019 02:23 PM PST It is well-known that homo sapiens interbred with Neanderthals. If this is the case, then why do we consider the two, different species? This could also to apply to other species, such as homo erectus and other members of the homo group. [link] [comments]  |
| Does cold do anything against acidity? Posted: 02 Mar 2019 02:44 AM PST Really general question, but it has two possible scenarios I'm thinking of:
I feel like, up to a certain point, a lower temperature shouldn't really affect acidity. There must be other facets to this though, maybe from a chemical perspective? [link] [comments]  |
