| Why is it so hard to shoot ICBM's out of the sky? Posted: 30 May 2017 04:21 PM PDT We have been working on this since the 80s. It seems like an impossible feat for that era of technology; However, in the last 18 years we have only hit 10 of 18 targets in testing. It is an awful long time between tests, and the results still vary. [link] [comments]  |
| Posted: 30 May 2017 07:37 PM PDT It has contributed in some areas such as Trinity and such, but has it made an impact on where most of civilization lives? Globally? [link] [comments]  |
| How did scientists measure the radius of atoms and other stuffs? Posted: 31 May 2017 05:58 AM PDT They can seem to measure very accurate things at 10 decimal places. How do they do it? [link] [comments]  |
| How do electronics keep track of time when they are turned off/ out of battery? Posted: 30 May 2017 06:07 PM PDT My iPod died a few months ago and was completely without power until a few days ago when I plugged it in. When it opened it was down to the second. It also wasn't connected to wifi. How does it keep track? [link] [comments]  |
| Posted: 31 May 2017 02:18 AM PDT Would they be able to compete with other predators like lions, hyenas, and crocodiles, or would they die out? (Assuming they can adapt to the environment) I know dinosaurs are supposed to be on average a lot larger and stronger than modern day animals, but I thought it was interesting the raptor called deinonychus only weighed 150 pounds (compared to a female lion which weights 280) was able to hunt other dinosaurs such as tenontosaurus which weighed around 2000 pounds (compared to zebras and water buffaloes which weigh around 1000 pounds). Would these dinosaurs dominate the food chain today? Or were they only specialized for the animals of their time and fail at hunting the herbivores of the savannah/Serengeti. [link] [comments]  |
| Why do polarised sunglasses make some screens difficult to read? Posted: 30 May 2017 03:21 PM PDT I'm a crane driver and find it hard to look at my instrument screens when wearing my polarised sunnies. It's difficult having to choose between reading my vitals and avoiding sun strike. [link] [comments]  |
| What does 'error variance' mean in this chart? Posted: 31 May 2017 02:59 AM PDT This is the chart in question. It's the results of a psychological study measuring the characteristics of mystical experiences. There are three groups of items: introvertive/extrovertive/interpretative, and I'm struggling to make sense of the numbers and what the implication is. [link] [comments]  |
| Can pions (or other mesons) form a "nucleus" by binding to other pions via the strong force? Posted: 30 May 2017 07:19 PM PDT For example, a π+ and π0 acting as the meson equivalent of the proton and neutron. Can this not happen because the π0 decays too quickly, or is there another reason? Also, if these meson "nuclei" can occur, are they potentially more stable than the constituent mesons (like neutrons become stable when bound in a nucleus)? [link] [comments]  |
| Would syringe hold liquid in vacuum? Posted: 30 May 2017 05:27 PM PDT As the tilte reads. I think it should, because it does hold water and it does not care about the atmospheric pressure. But also, shouldn't the liquid vaporize? What if syringe would hold liquid with much higher/lower density in medium which has much lower/higher density than the liquid inside the syringe? Would the liquid also hold? [link] [comments]  |

| If I point randomly into the sky, how likely is it that I'm pointing at a star? Posted: 30 May 2017 03:52 PM PDT Edit: phrased differently, If I extend a line from the tip of my finger to the edge of the observable universe, what's the probability that that line intersects with the body of a star? This was inspired by reading about Olber's Paradox or the "dark night sky paradox". [link] [comments]  |
| What is used to date old stone tablets? Posted: 30 May 2017 11:01 PM PDT I was curious and tried to find the oldest known piece of writing and in seeing all the stone tablets I was wondering how their age is determined. With old papyrus or parchment they can use radiocarbon dating to find out when the paper was made to have a rough idea. I know rocks can be dated using different radioactive dating and magnetic dating techniques but that just tells you when the stone was made not when the story was written. Even if you date the layer they are in wouldn't that just tell you when that rock was created? [link] [comments]  |

| Posted: 30 May 2017 05:32 PM PDT Where do cosmic rays come from in large quantities? I know that some of them come from the sun, but where else? And, hypothetically, say that a team of astronauts on a space shuttle happened to venture into an area with a lot of cosmic rays. How would they protect themselves, if they even could? If they couldn't, what would be the effect? [link] [comments]  |
| What happens to the parts of the brain which control amputated body parts? Posted: 30 May 2017 04:00 PM PDT |
| How would relativity affect the "length" of speed of light data transfer like a radio transmission? Posted: 30 May 2017 04:39 PM PDT Let's say that I was to send a 10 second long Radio Transmission from an object going 0.9 the speed of light relative to another receiver. Would that receiver get a "sped up" and compressed radio transmission? [link] [comments]  |

| How Does Auto-Shut Off Engine Design Not Destroy Engines? Posted: 30 May 2017 09:30 AM PDT I rent cars quite a bit for work and over the last six months I have gotten a handful that have a feature where they basically shut off when the car stops and then start back up when the car tries to move. I've been told starting up the engine is one of the harshest things an engine goes through, yet this approach to design seems to unnecessarily add a ton of off/on cycles to a drive. Is the notion / assumption that start up is the harshest out of date or are special precautions taken to mitigate the damage of this particular feature? [link] [comments]  |
| Why does the current decrease when the voltage increases in the National Grid? Posted: 31 May 2017 03:27 AM PDT In school I learned that in circuits that voltage and current are proportional to each other; when one increases the other does aswell. In the National Grid however, the opposite seems to happen. Is it something to do with the transformers or that it's an alternating current? Thanks! [link] [comments]  |
| Does lepton number have to be conserved in nuclear decay? Posted: 31 May 2017 03:21 AM PDT I was looking at examples of radioactive decay earlier, and I noticed something strange. In an alpha emittance example, it gave Uranium-238 decaying to Thorium-234 via the emittance of an Alpha particle and a neutrino. Why would a neutrino be produced here? As far as I'm aware, conservation rules apply to all decays don't they? There are no leptons on the Uranium side, so all it does is offset the balance. [link] [comments]  |
