- How do we know what Ancient Egyptian (or any ancient language) sounded like? How accurate are names like “Osiris” and “Tutankhamen” to what they actually sounded like when spoken by Ancient Egyptians?
- Why do we have a depression in our skin above our upper lip? Does this have any significant purpose?
- Is Current Audio Amplification Technology at the Limits of Physics?
- Why light doesn't lose speed when affected by gravity?
- When you wash your skin with lukewarm or hot water after you’ve been in freezing temperatures, why does it feel like the skin is burning? Is your body actually in danger or are the nerves misinterpreting what is happening? Are there other examples of this situation?
- Have scientists found any meteorites with a substantial concentration of precious metals?
- Do birth control pills affect attraction/mate-choice?
- Why does the human brain contain folds? Are they indicative of something else?
- Does the earth take up less space during an ice-age due to thermal expansion?
- What does the body do with all that extra keratin protein when someone goes bald?
- Why don't anti body's protect you from flu season?
- Why is it itchy on the elastic part of the socks, bra etc.?
- How does an animal with static camoflauge know where to hide?
- How often do the planets of our solar system have the same exact alignment?
- Why is the milkyway galaxy depicted as having a bright center, if we really have a huge blackhole?
- Why are Ramsey Numbers so difficult to find and would finding an efficient algorithm for finding Ramsey Numbers have any benefit for mathematics in general?
- In Planet Earth, the Okavango Plains are flooded from rains that happened 5 months ago in the Angoland highlands. How much water fell in order to still be able to create a water-based paradise? How did it not all evaporate/get used by animals, plants, etc?
- If a flu shot has a certain percentage of effectiveness, does that mean it is more effective against some of the strains than others?
- Psychedelic drugs are now in the spotlight due to their therapeutic uses. Alcohol is often eschewed for its negative effects. Are there any known therapeutic uses for alcohol that can result in positive psychological changes over time?
- If I was floating in space and only needed to maintain my body temperature to survive, how far from the sun would I need to be to maintain a stable safe bodily temperature?
- Why are alkane gases like propane so flammable considering that they are non-polar compounds?
- Does the body actually absorb all of the vitamins in a supplement?
- What is the biological purpose of having an allergy? I don't see how it can possibly benefit an organism.
| Posted: 29 Jan 2018 03:21 AM PST Egyptian is just an example in this question, and this can apply to Ancient Mayan mythology, or pretty much any ancient religion/society This has always confused me. Where do our anglicanized names like these come from and how confident are we that this is what these historical and mythological figures were called by ancient peoples? [link] [comments]  |

| Is Current Audio Amplification Technology at the Limits of Physics? Posted: 29 Jan 2018 02:55 AM PST I'm a full-time busker and have been wondering about the physics behind audio amplification and speakers lately. I currently carry about 15kg (20 if you count the guitar) worth of battery-powered PA equipment around and even with that weight, the amplification reaches to about only 50 people in an open venue. I am wondering if speaker/amplification technology has hit a ceiling when it comes to efficiency and weight relative to dispersion and volume? Should we be looking forward to a future when we can use 5kg worth of amplifying equipment to reach a crowd of hundreds or is that just plain physically impossible? Thanks! [link] [comments]  |
| Why light doesn't lose speed when affected by gravity? Posted: 29 Jan 2018 04:43 AM PST I know it changes frecuency, but it sounds like an exception to the rule. [link] [comments]  |

| Have scientists found any meteorites with a substantial concentration of precious metals? Posted: 28 Jan 2018 10:55 PM PST I've read that in the distant future asteroid mining will be a big deal. I'm wondering that if there is lots of gold and other precious metals to be found in the asteroids then have people already found meteorites that have gold in them? [link] [comments]  |
| Do birth control pills affect attraction/mate-choice? Posted: 28 Jan 2018 05:52 PM PST I read something that said that birth control pills affect a womens attraction. Specifically that women will choose lower testosterone males who are more genetically similar to them on the pill. If they come off the pill they will become more attracted to higher testosterone and more masculine men. Im wondering about how reliable these studies are? Is it enough to conclude that there is a definite link? Are the sample sizes large enough? If its true it could have a large impact on long term relationships or marriages [link] [comments]  |

| How does an animal with static camoflauge know where to hide? Posted: 28 Jan 2018 11:56 PM PST For example: how does a leaf-tail gecko know that it is hiding on the correct tree bark? [link] [comments]  |
| How often do the planets of our solar system have the same exact alignment? Posted: 28 Jan 2018 11:34 PM PST For example, when was the last time all the planets were in the exact same position that they are in today? [link] [comments]  |
| Why is the milkyway galaxy depicted as having a bright center, if we really have a huge blackhole? Posted: 29 Jan 2018 05:20 AM PST I know there's a huge blackhole in the center of the milkyway, but was wondering why the milkyway Galaxy is frequently depicted as having a bright white center. Thanks! [link] [comments]  |
| Posted: 28 Jan 2018 11:19 PM PST I was looking at Ramsey's Theorem (from which the party problem was created) and was surprised to realize that the Ramsey Number for (5,5) is still currently unknown. This problem at first seems deceptively simple. 1) Is an efficient algorithm possible to find Ramsey numbers? 2) Would finding such an algorithm be a "big deal" for mathematics? 3) Would a quantum computer be more useful than a classical one for this type of problem?

| Posted: 28 Jan 2018 04:17 PM PST So in the current epidemic, if the flu shot is 40% effective, what is the actual effectiveness against the worst strain? And how does that effectiveness play out? More effective against a smaller exposure to the virus, or having more to do with the health and age of the infected? [link] [comments]  |

| Does the body actually absorb all of the vitamins in a supplement? Posted: 28 Jan 2018 10:37 PM PST I started taking a multivitamin. The label has more than the daily recommended values for most of the vitamins in it. If we did absorb and purpose the whole amount, wouldn't we have a toxicity risk? [link] [comments]  |
