| How do quantum computers perform calculations without disturbing the superposition of the qubit? Posted: 17 Jan 2019 02:53 AM PST I understand the premise of having multiple qubits and the combinations of states they can be in. I don't understand how you can retrieve useful information from the system without collapsing the superposition. Thanks :) [link] [comments]  |

| Do winter droughts exacerbate summer wildfire conditions? Posted: 17 Jan 2019 04:14 AM PST I can see both scenarios occurring: winter droughts leave spring and summer conditions especially dry. I can also see winter droughts not allowing underbrush such as grasses to grow which may alleviate wildfire conditions. [link] [comments]  |
| What would solid Roentgenium look like if it was stable? Posted: 16 Jan 2019 04:56 PM PST Since it is is the same group as gold i was curious what it would theoretically look like if there was a stable form of it [link] [comments]  |
| Why can’t fish breathe in air? Posted: 16 Jan 2019 09:05 PM PST And the answer can't be "because fish breathe water, idiot! Everyone knows that!" But really though, fish can breathe underwater because oxygen is soluble in water at certain temperatures, and as the water passes through their gills, they extract this oxygen from the water. Then why is it, then, that when fishes are out of the water, that they can't absorb the same oxygen that is so much more plentiful in air than in water? [link] [comments]  |
| Posted: 16 Jan 2019 12:44 PM PST A more watered down question would be, "When our nerves react to temperature, is it objective to the bodily temperature?" [link] [comments]  |

| How are black holes detected by scientists? Posted: 16 Jan 2019 03:27 PM PST Ever wonder how black holes are detected by scientists? I mean, they are the purest form of black and can absorb all light. Doesn't his mean that the area is pretty much unseeable like the rest of space? Let me know what you guys think!

| Is it possible that some of the puzzle slides are unsolveable? Posted: 17 Jan 2019 02:36 AM PST Example for 3x3 number puzzle: (From top left) 1, 2, 3, 4, 5, 6, 8, 7, (blank) [link] [comments]  |
| Is the oxygen level in air the same at sea level as the top of a mountain? Posted: 17 Jan 2019 02:36 AM PST I'm having trouble to grasp whether oxygen level stays the same at sea level as at the top of a mountain? I have heard that there is less oxygen on top a mountain but I also read that "...relative percentage of oxygen in air, at about 21%, remains practically unchanged up to 21,000 metres (70,000 ft)." (source: https://en.wikipedia.org/wiki/Altitude_sickness). Anyhow my questions are:

| Biologically, what makes the difference between different strains of cannabis? Posted: 16 Jan 2019 07:32 PM PST The two main branches of cannabis, indica and sativa, have two seemingly opposite effects. One makes you sleepy and one makes you active. Even within the branches themselves there are strains which differ in terms of physical properties like color and density, and also in how the high is felt by the user. One might give you dry-mouth, and another won't. One might make you paranoid, and another will make you giggly. Do we know what causes these differences? [link] [comments]  |
| How do turbine engines power things like tanks and ships? Posted: 16 Jan 2019 02:14 PM PST I understand how a jet engine works (kind of), but how is that hot expanding gas harnessed to power something like a ship's screw or a tank's drive wheels? [link] [comments]  |

| Posted: 16 Jan 2019 02:24 PM PST In other words, if a new study brings to light the fact that there is supporting evidence that would change the way a specific orthopedic treatment is approached, what must occur for it to be accepted into the standard/preferred approaches for treatment? More case studies? Or does it just a slow process of adoption by Doctors in the field? Not talking about a night-and-day difference discovery, but something more like the timing and duration of a given treatment. [link] [comments]  |
| What determines how fast a shower changes temperature? Posted: 16 Jan 2019 08:24 AM PST Some shower changes the temperature of water as soon as you turn on the faucet, while others can take 10 seconds before anything happens. The shower I have now changes instantaneously, while I have experienced the exact opposite most of the time. What determines this and what can you do to make your shower respond as quickly as possible? [link] [comments]  |
| Is the large scale structure of a baby's brain the same as that of the adult brain? Posted: 16 Jan 2019 12:35 PM PST Babies and adults have basically the same number of nuerons. But their brains clearly don't act the same way. My question more or less is, is the difference between a developing and a developed brain the local connections (within a specific lobe or region) or the large scale connections (the connections between two separate lobes or regions) or is it a bit of both?

| Posted: 16 Jan 2019 08:26 AM PST I was reminded recently that we will never know about the vast majority of extinct prehistoric creatures due to the spotty nature of fossilization. Dark energy and dark matter were theorized based on speculation, and I was wondering if that principle could be applied to prehistoric life. For instance, if it was known that certain animals existed in an area in the same time period, could that be used as evidence for the existence of a different animal, even if there are no fossil records of such a creature existing? Are there any examples of prehistoric animals that are speculated/theorized/presumed to exist, even if there is no fossil evidence to affirmatively prove it? And have there been any prehistoric discoveries that match up with a speculation like that? [link] [comments]  |
