| Posted: 06 Nov 2016 01:10 PM PST Being new born, I would presume there's no way they could 'know' that the racer snakes have bad eye sight and therefore it's a good defense mechanism. If its somehow known instinctively could someone explain the mechanisms behind how? Thanks! [link] [comments]  |
| Do we know how or why five-sided symmetrical organisms evolved? Posted: 06 Nov 2016 07:50 AM PST The majority of multi-cellular life here on earth is bilaterally symmetric. However a notable exception is the large class of sea-living invertebrates known as echinoderms (starfish, sea urchins, etc), which typically exhibit radial five-sided symmetry. However reading Wikipedia it states that "[t]he larvae of echinoderms have bilateral symmetry but this is lost during metamorphosis when their bodies are reorganised and develop the characteristic radial symmetry of the echinoderm, typically pentamerism". My understanding of evolutionary biology is low but the above suggests to me that an ancient bilaterally-symmetrical ancestor of modern echinoderms found some benefit to this body layoutt -- but it strikes me as an extremely odd mutation. Is there any knowledge or evidence about how, why, or when this might have occurred? [link] [comments]  |

| How do you increase the amount of information a picture can hold? Posted: 06 Nov 2016 01:12 PM PST I was watching a gif zooming in on a high resolution picture and I am curious how some pictures can hold more information (detail) than others. Also: how does resolution measure this? [link] [comments]  |
| What, specifically, are the most "useful" traits of quantum mechanics? Posted: 06 Nov 2016 01:51 PM PST A common refrain in popular science programs(Michio Kaku, Brian Greene, N.D. Tyson...) is that the modern world and economy couldn't function without the exploitation of quantum mechanics. But they usually don't describe the specific properties that are the most useful, and how they are applied and exploited. So, what are they? [link] [comments]  |
| does a radioisotope like Ir192 produce x-rays? Posted: 06 Nov 2016 05:23 PM PST Ir192 is used for ndt but i dont get how a radioactive material produce xrays. [link] [comments]  |
| What causes temporary deafening and ringing when in the presence of a loud, concussive blast? Posted: 06 Nov 2016 02:05 PM PST As the title says, I'd like to know what specific things are happening that cause ringing and temporary deafness in our ears when we experience some sort of trauma via pressure/blast waves. Examples:

| Why can't E1 and E2 reactions simultaneously occur? Posted: 07 Nov 2016 01:30 AM PST Why does the reaction have to be only one of them? Can't a single reaction be both E1 and E2 if the necessary conditions (nucleophile strength etc) are met? [link] [comments]  |
| Are there any examples of animals practicing medicine in the wild? Posted: 06 Nov 2016 08:04 AM PST From simple things as eating certain herbs when they feel sick to preparing any types of salves or even as complicated as mending wounds, are there any animals that do this or is this just something humans do? I know elephants have their young eat feces so they get the necessary bacteria in their stomachs to digest the greens they eat and I guess that's sort of medicinal, but what are, if there are any, other examples?

| How do pion and kaon condensates work? Posted: 06 Nov 2016 12:55 PM PST Im specifically interested in how they interact in hypothetical neutron star cores. There aren't a ton of places that detail them in very understandable terms. I understand their basic concepts of being able to form condensates due to baryonic properties, but where do they all come from? Do nucleons come apart and their quark building blocks come together to form these particles or what? [link] [comments]  |
| How does helium affect instruments? Posted: 06 Nov 2016 10:50 AM PST If instruments were played in a chamber filled completely with helium (or other non-oxygen gas), how would it affect the pitch/timbre of the instrument? Would it affect different instruments (wind/string/percussion) differently? I'm a musician & sound engineer, so I understand specifics of music, instruments, and basics of the physics of sound.

| Does air pressure affect the amplification of sound? and if so how does it affect sound waves? Posted: 06 Nov 2016 02:01 PM PST I wanted to know if for example, a sound was reproduced in a high pressure or low pressure environment would it affect its amplitude? An example would be shouting on top of a mountain, is it perceived louder because of the air space or is it also amplified by the low pressure environment. [link] [comments]  |
| When catching a ball, how do the hands position themselves to catch the ball? Posted: 06 Nov 2016 08:21 AM PST What I mean by this is that if the head is focusing on the ball, how do the hands position themselves in three dimensional space in order to catch the ball? [link] [comments]  |

| Why do we call different groups of animals by different names (e.g. herd, pack, pod, etc.)? Posted: 06 Nov 2016 08:39 AM PST Why do we call different groups of animals by different names (e.g. herd, pack, pod, etc.)? Is there a scientific reason behind this linked to behavior or function?

| What is the typical pH range of freshwater environments? Posted: 06 Nov 2016 01:43 PM PST Hey all, I need a decent reference for my PhD thesis on the pH of freshwater systems, but I'm struggling to find any primary literature. I've got 6-8 as a starting point, but not from any reputable sources. Can anyone help with this? Thanks! [link] [comments]  |
