Can you enlarge the radar cross section of a aircraft? Posted: 08 Feb 2020 10:56 PM PST So if stealth works my making your radar cross section smaller thus having you register as a much smaller object than you really are, can you do the opposite and say make a smallish drone appear as the size of a fighter/bomber to feint an oncoming attack?

Posted: 08 Feb 2020 11:07 PM PST Since the immune system has cells that specifically target viruses, it's possible for "cellular" life to win against viral pathogens. It seems reasonable to assume that part of the bacterial microbiome could play a similar role but my searches are coming up empty on this. [link] [comments] |
Posted: 08 Feb 2020 03:09 PM PST Has there been an experimental design where bees or other social insects are put in a situation where from conception they cannot observe any peers? And do they exhibit the same or similar complex social behavior as their peers? Is the neural arrangement that gives rise to their behavior entirely arranged through the formation of their body (genes) or is it sufficiently plastic and dependent on observing other insects for proper functioning?

Why is the seam of a treadmill belt always on a diagonal? Posted: 08 Feb 2020 12:36 PM PST Is there a scientific or structural reason that the belt seam needs to be diagonal as opposed to horizontal? Or is this purely aesthetic? [link] [comments] |

Where does candle wax go? What does it produce? Posted: 08 Feb 2020 08:52 AM PST Where does the candle wax go when you burn a candle? Does it evaporate? Does it burn into a carbon? How does it effect the air, space in the room it's burnt? [link] [comments] |
What color would Nitrous Oxide be in a solidified form? Posted: 08 Feb 2020 04:19 PM PST Been wondering forever, sorta Nitrous Oxide enthusiast. Cars, rockets, laughing gas, whipped cream, all awesome. I've always wondered, if reduced to liquid or solid form, what actual color would it be? Tons of research, could never find an answer other than "it's colorless when a gas", but it's gotta have some color when in abundance, right? [link] [comments] |
How much radiation is an astronaut exposed to on the moon? Posted: 08 Feb 2020 09:46 AM PST I know it's meant to be a lot but I need something for comparison. How would it compare to a CT scan? [link] [comments] |
