| Is light affected by gravity ? Posted: 12 Jun 2018 01:43 AM PDT I was watching a documentary about Albert Einstein this morning and it was said that light from stars are deflected by celestial objects like the Sun for example because of its attraction. It means that stars are not really where we are seeing them from Earth. Is this a true statement or has it been refuted ? Thanks for taking the time to answer. [link] [comments]  |

| How are memories stored in the brain? Are they electrical, material or...? Posted: 11 Jun 2018 11:41 AM PDT How is a memory formed, stored and recalled? The way I simply picture it as, is an electrical signal created during an experience, and that gets stored in the brain. So it's like a computer's virtual ram... information exists as long as there is electricity in the system (being alive) and gets deleted when you power off (death). Is there no "hard writing" of memories on the brain (like on hard spin drives)? Following that... why are only part of a memory usually recalled? Thank you [link] [comments]  |

| Low frequency, high frequency and WiFi ? Posted: 12 Jun 2018 05:06 AM PDT Q1. Do lower frequencies pass through matter better than higher frequencies or, is it the other way around. What is the proper explanation, has it got to do with the higher frequency having more energy than lower frequencies. Q2. So what frequency does WiFi use. Q3. What's the definition of bandwidth and what does it do for WiFi. [link] [comments]  |
| Posted: 11 Jun 2018 12:24 PM PDT Does the star begin to use helium gradually, as the hydrogen is depleted? Or does the process of fusing helium into carbon not start until the last hydrogen atom has been spent? Or do I misunderstand completely? [link] [comments]  |
| What are raw ingredients used in artificial flavors? Posted: 11 Jun 2018 07:38 PM PDT FDA defines artificial flavors as; "any substance, the function of which is to impart flavor, which is not derived from a spice, fruit or fruit juice, vegetable or vegetable juice, edible yeast, herb, bark, bud, root, leaf or similar plant material, meat, fish, poultry, eggs, dairy products, or fermentation products thereof." Are these all really never used in artificial flavors? I am curious to know what natural ingredients are that make up the 'strawberry', or 'orange' flavoring. [link] [comments]  |
| What would be the purpose for a quartz tube in an induction annealer? Posted: 12 Jun 2018 01:35 AM PDT I run a stainless steel tube mill at a factory that creates evaporative condensers. After we weld the tube together we run it through an induction annealer and heat it up to around 2000°f so that we can hydraulically expand it once it's in a unit. The induction coil in the annealer contains a quartz tube. What purpose would this tube serve? [link] [comments]  |

| How do animals such as basking sharks fare with plastic pollution? Posted: 11 Jun 2018 01:29 PM PDT Do they consume more plastics than other fish? And what sort of damage is it having on them individually and as a species? [link] [comments]  |

| When is an island no longer just an island? Posted: 11 Jun 2018 11:34 AM PDT Imagine an island forming somewhere like in the pacific ocean. How large should that new island have to be to no longer be considered just an island but perhaps a continent? Or are there factors other than size which determine this perhaps? [link] [comments]  |
| How does a stroke affect the different bodily functions like hair growth, sweating or nail growth? Posted: 12 Jun 2018 02:10 AM PDT For example when a person is paralyzed on one side. Does it change how the body sweats or the body hair growth or even hearing on that side? Or is there no effect at all because its not controlled by nerves maybe? [link] [comments]  |
| Why do instruments create overtones/harmonics and not just a sine wave? Posted: 11 Jun 2018 01:37 PM PDT Hi I'm a musician and in my classes we've been learning about the overtone series. They use the example of a guitar string that when plucked vibrates along its whole length (the fundamental) but also vibrates in two equal parts, in three equal parts, etc creating higher pitched overtones. But why does the string or other instruments create these overtones and not just a sine wave?Thanks! [link] [comments]  |
