- What's the significance of oxidation number in a covalent bond? Are the electrons shared, or aren't they? (rephrased my awkward question from yesterday)
- During beta decay, when a neutrino and a beta ray are created, where does it's mass come from?
- How is the Moon covered mostly fine dust if the erosion forces of wind, water, and plate tectonics do not exist?
- ARC - A nuclear fusion reactor from MIT smaller and cheaper than ITER - a year has passed and no one talk about it. Why?
- Why dont plants suffer from the effects of aging and cancers like mamals do?
- Nuclear fission and fusion have been explained to me as "opposites." Why do they both produce energy?
- Using QFT or String Theory, why would an electron be attracted to/more likely to exist around positive charges such as protons?

| How are black/white photos colorized? Posted: 30 Jun 2017 07:38 AM PDT I think the post is pretty clear... How to people colorize black and white photos with such accuracy and stuff? [link] [comments]  |
| Was there an evolutionary advantage to different hair colors in humans? Posted: 30 Jun 2017 06:11 PM PDT Basically what the title says, and I know how different hair colors are a result of different proteins and melanin, but how do the did the different range of colors help humans in earlier time periods adapt to their environments and have higher survival rates?

| Does writer's block have a neurological foundation? Posted: 30 Jun 2017 06:43 AM PDT I'm just wondering if anyone has brain-scanned someone suffering from writer's block. Can you see a downturn in the various language areas of the brain? Is it a measurable phenomenon or is it one of those "too-subjective-to-be-measured" things? [link] [comments]  |
| Can you train your memory to be better? If so, is there any limit to how far you can take it? Posted: 30 Jun 2017 05:28 PM PDT If someone trained their whole life would they have near-photographic memory? [link] [comments]  |
| How powerful is the laser in a typical fiber optic cable? Posted: 30 Jun 2017 07:11 PM PDT Just want to know in Watts the approximate power of a laser in a fiber optic cable that would be used for something like internet providing or similar fiction. If possible the input strength and output strength, say over 10 meters. [link] [comments]  |

| Posted: 30 Jun 2017 05:22 PM PDT I watched some birds grow from eggs tohatchlings and, now that they are gone, I am hoping they will come back next year. Do birds ever reuse their nests? [link] [comments]  |
| Posted: 30 Jun 2017 03:10 PM PDT If languages evolved separately, why do they all contain this particular quirk? In almost every single language I've come into contact with, raising your tone at the end of a sentence means that you're asking a question. [link] [comments]  |

| Posted: 30 Jun 2017 07:01 AM PDT If I remember right there was a point where the moon had mildly active plate tectonics (correct me if I'm wrong), but I still don't understand what other than meteor impacts could cause any erosion on the surface, let alone enough to make a fine dust. Also on a side note, I know that relative to Earth meteoroids are called meteors when traveling through the atmosphere and meteorites when they've impacted the ground, but how should they be referenced in relation to the moon since it has no atmosphere? Edit: Despite proofreading my post I still have a typo in my title. Frick. [link] [comments]  |

| Why dont plants suffer from the effects of aging and cancers like mamals do? Posted: 30 Jun 2017 04:39 AM PDT So bare with me its been a while since my last biology class. If the semi-conservative replication of DNA causes degredation over time which leads less and less acurate copies of DNA strands is attributed with causing the visable effects of aging, and higher occurances of cancers. Then how can plants such as redwood trees live for hundreds of years with out simply dying of old age ? [link] [comments]  |
