| Mouse Utopia: Were the results ever replicated in other experiements? Posted: 24 Jun 2016 06:22 PM PDT I recently learned about John Calhoun's mouse Utopia, and despite the numerous trials he did with the rats; was the experiment results ever obtained in other similar experiments? If so, was the experiment with rats or other animals? If not- would it be unethical by today's standards to replicate the experiment in a different setting? [link] [comments]  |
| Posted: 24 Jun 2016 09:26 PM PDT In order for me to continue past the periapses "as normal", I would have to be going faster than the speed of light, which is not possible. Would my spacecraft slowly approach the speed of light and gradually accelerate slower, or hit the "speed limit" and stop accelerating abruptly? Assume that there is no debris/acceleration disk orbiting the black hole and that I will not be instantly spaghettified close to the black hole. [link] [comments]  |
| Why are most heatwaves broken by a storm? Posted: 25 Jun 2016 07:54 AM PDT I am curious about how the events that would most likely lead to a storm forming after a heatwave. [link] [comments]  |
| What is the furthest traveling organism in proportion to their size? Posted: 25 Jun 2016 07:47 AM PDT How far do they go in respect to humans and does anything come close to lunar or even mars travel? If so what are their adaptations? [link] [comments]  |
| Why do musical instruments get sharp (higher pitched) as they warm up? Posted: 25 Jun 2016 07:44 AM PDT This one is from my mum who teaches flute and conducts a wind band. As you play, the instrument warms up, and the pitch it plays the same note goes up; this is exacerbated further in warm weather. In order to compensate, you lengthen the tube to make the note lower again. What confuses us, is that surely the expansion of the metal as the instrument warms up causes the tube to become longer; so why does the pitch go up? [link] [comments]  |
| Why do we use aluminum/aluminium to massively manufacture liquid containers? Posted: 25 Jun 2016 07:34 AM PDT I just think this statement sounds funny: "We extract metal from the earth and process it just so we can have it temporarily hold a liquid before being discarded or recycled". To me it sounds funny when you consider there is a period of time where we just used ceramic/clay containers to hold our liquid which are really easy to produce on the small scale because it doesn't require a whole lot of technology. Anyways do we use aluminum because it's cheaper and easier to massively produce or is it something else? [link] [comments]  |
| Are all body parts proportional to each other in any way? Posted: 25 Jun 2016 06:56 AM PDT I mean this as, for example, if you were to measure the height of two different people, and then proceeded to compare it to their respective arm length, would the proportion be somewhat the same despite different numbers?

| Why does the solubility of helium act differently in the 20º-30ºC range? Posted: 25 Jun 2016 06:44 AM PDT As seen in this picture (http://docs.engineeringtoolbox.com/documents/1148/solubility-he-water.png) why does the solubility of helium actually go back up and then drop again within that range?

| Posted: 24 Jun 2016 05:33 PM PDT I'm talking about speed of light. Let's say I point to an area that takes 1 minute for light to travel to it. I see the beam on the planet then pan the beam to another spot that is also 1 light minute away, but the distance between those two objects are 3 light minutes apart...would the beam travel faster than light to make the trip? I'm not sure how to word this into google. [link] [comments]  |
| How do birds innately know how to build nests? Posted: 24 Jun 2016 03:12 PM PDT From my understanding of genetics and inheritance, DNA produces proteins which have different "tasks" in bodily functions. My question is how can a bird know how too build a nest through proteins, or is there another part of the picture I am not aware of. It just seems impossible to me for a bird to be born with the knowledge of which sticks should be used, where mud should be applied to reinforce the nest, and what a proper location for a nest is. I have a minimal understanding of how neurons work and how a bird would be able to learn how to build a nest. [link] [comments]  |

| Why does expanding gasses become cold? Posted: 24 Jun 2016 08:31 PM PDT I know that in an adiabatic free expansion gasses expelled into a vacuum lose heat, the question is why does it do this? Is it a function of entropy or some other mechanic? [link] [comments]  |

| If all matter has a gravitational pull, why isn't universal expansion slowing down or reversing? Posted: 24 Jun 2016 12:44 PM PDT I understand our best bet is the Big Bang Theory which would explain the initial acceleration and rapid expansion. I also understand that all matter is affected by gravity. Logically speaking, the matter in the universe should slow down and stop. Eventually the matter would meet back at a center point, get extremely dense, and reactivate the Big Bang. So what am I missing? What is the best or most logical explanation as to why this IS NOT happening? [link] [comments]  |
| Posted: 24 Jun 2016 03:02 PM PDT So, my question is about the matter on those two videos: This one from Veritasium and this response to the first one. It seems that there's more about the electrostatic deflection of water than those videos can explain, and I can't find a more complete explanation. That's what i want to know: Are there more complete experiments (and explanations) including pure polar and non-polar fluids, and then using ion-rich polar and non-polar fluids? And, if there's any, papers with complete data sets from experiments like those? Thanks. [link] [comments]  |
| What is the maximum height or level our oceans could rise in relative to our atmosphere? Posted: 24 Jun 2016 03:50 PM PDT What I'm basically asking is if by some force of nature all of our oceans started to rise and not stop, at what point would they stop before they hit our atmosphere? EDIT: Which layer could it rise to physically? (stratosphere,mesosphere,thermosphere,exosphere) [link] [comments]  |
