| How exactly does the rabies virus control human beings (stop them from drinking)? Posted: 25 Mar 2018 01:21 AM PDT What is the mechanism the virus uses to control human behavior? Does it override programs in the motor cortex? Does it program fear of water in the amygdala? Or does it just block muscles in the throat? I find it very hard to understand how a virus can manipulate something as complex and deliberate as human behavior. Video [link] [comments]  |

| Posted: 24 Mar 2018 07:00 PM PDT To clarify: 1) Just because we can currently observe the universe accellerating does in no way, shape or form mean it will do so forever? As a metaphor. If I throw a ball really hard, then it will accellerate at an increasing rate before slowing down, stopping, or bouncing back. I don't understand how we being able to observe the universe expanding now, no matter how rapidly, is evidence that it will never slow down, halt, or rebound. Considering a cosmic timeframe, our observation of the motion of the universe would be insignificantly small compared to the full motion in question. 2) Wouldn't our very existence be proof of the big freeze being wrong? By that I mean: If the universe could end / was finite. Then the odds of us existing would be non-existent? Scenario A) The universe is finite Scenario B is likely, because we exist. 3) The big crunch is the theory that best explains the nature of existence? If the universe has a mechanism that causes it to explode/implode infinitely, then it fits the law of conservation of energy perfectly, as well as explaining how probable it is that we exist in the first place?

| Posted: 25 Mar 2018 12:44 AM PDT I know that blue paint reflects blue light and absorbs for example red light, but I would like to know why it does that. What happens inside the paint? [link] [comments]  |

| What does it mean to say there is a frequency associated with an analog signal? Posted: 24 Mar 2018 04:25 PM PDT When performing measurements using analog instruments such as a thermocouple, there is an output signal such as voltage that can be used to determine the temperature of the hot end of the thermocouple. But since the output voltage is constant, assuming its a stead state process, why is there a frequency associated with the signal? Won't the signal consist of a single voltage reading? (and random variations due to noise) So over time, the voltage vs time plot will show a straight line generally speaking, with some noise fluctuations. What is the function of something like a low-pass filter in this scenario? How can there be a frequency if there is no periodicity in the signal? [link] [comments]  |

| Posted: 24 Mar 2018 05:49 PM PDT I was Musing the little I know about the strange quantum universe... I understand the double Slit Experiment, the importance of finding an interference pattern, and how that I helped form the uncertainty principle... What got experimenters to even start thinking that direction? [link] [comments]  |

| Strong/weak nuclear forces vs. gravity - can I just combine them? Posted: 24 Mar 2018 08:38 PM PDT Let's imagine for a second that combining the 3 forces into 1 overall attraction/repulsion function based on distance would be used for a particle simulator I am writing for curiosity sake. This is what the function would look like: https://i.imgur.com/7vLhjy2.png The concept being that as a new particle position is calculated, instead of calculating the strength of each 3 forces seperately, just do it all in one shot. When the function returns a positive value from the green region, they are attracting based on the effect of gravity - green region. When there is enough force to push them past the negative function return - red region - they will be bound together. The coulomb barrier would represent the magnitude of the red region, binding force in the blue region, etc... The specifics of the function in terms of distance ranges and magnitudes can be put in for accuracy. The motivation for looking at it like this is for a particle simulator I am writing: https://www.reddit.com/r/Simulated/comments/86utfm/digital_phyics_saturday_halfway_decent_particle/ and am having a heck of a time trying to get the particles to become stable and bind together to form nuceli. Despite my best efforts to calculate the 3 forces individually and apply them only results in particles scattering around and never fully accurately modeling what they should be doing. I cannot seem to find any references towards the concept of combining them into a single function. Is this something which has already been looked at in physics? [link] [comments]  |
