- hat has changed, technologically speaking, to allow people to fly around in Bathtub Drones like the guy on YouTube? We've had propellers, radio-controls, batteries, for years. Is it just that the design of the drone in general is so innovative as to have been a total game-changer?
- Pulsars have a very regular pulse frequency from our perspective, but since these are super massive objects that distort spacetime, how would those pulses be perceived for an observer extremely close to one of those objects? Would pulses slow down? Speed up?

| How does the Meltdown patch work? Posted: 15 Feb 2018 12:43 AM PST Before I ask the question, please tell me if my understanding is wrong as I am still learning about computer architecture: Modern CPU's utilize out of order execution, which means instead of waiting for each instruction cycle to finish, it will start fetching other instructions. So if there are branch dependent instructions, the CPU will need to predict what data will be coming from the branch (branch prediction) If the prediction is wrong, the register will remove the data, and it will be gone in theory, but in practice they are stored in the cache. (This is where I think I'm gonna be wrong) And through cache side channel attack, attackers can get data. Now what has the kernel memory got to do with this, and how does the KAISER patch slow down the CPU? [link] [comments]  |
| Posted: 15 Feb 2018 01:20 AM PST Due to the earth being round and gravity, there is no definitive way to know which way is top. So is the north top or bottom? In fact, is there a top or bottom in the whole universe? [link] [comments]  |

| Posted: 15 Feb 2018 07:26 AM PST I'm curious if there's something special about microwaves or if waves in other portions of the electromagnetic spectrum could, in theory, be used to heat food. I'm inclined to say 'no' since visible light hits my food all the time without warming it but it could be a matter of concentration. Is the choice of microwaves an economical (vs. scientific) one?

| My friend's farts always smell like death. Do people really have distinctive fart smells? Posted: 15 Feb 2018 06:20 AM PST Silly question but a valid one nonetheless: do people have different gut bacterial populations? Can that influence the way they smell? [link] [comments]  |

| Do different blood types dry different colors? Posted: 14 Feb 2018 07:40 PM PST I'm watching an Australian series, The Doctor Blake Mysteries, and he often has a paper chart with dried blood samples to compare with blood samples to determine blood type. Is this late 50s/1960s pseudo-science, or do different blood types dry slightly different colors? [link] [comments]  |

| Why are pre-historic drawings so ugly? Posted: 15 Feb 2018 04:46 AM PST Is it because bad hand-motoric development or lack of need to draw better? Or did "painters" just die too early? [link] [comments]  |
| How much of the sun's hydrogen will undergo fusion? Posted: 14 Feb 2018 09:53 AM PST If I've understood correctly, the sun is not entirely convective. The core, where fusion happens, largely doesn't exchange material with the rest of the sun. This would mean that only the hydrogen already inside the core will eventually undergo fusion. My question then, is this: how much of the total hydrogen in the sun will actually fuse? I.E. When the sun dies, how much of its mass will still be hydrogen? [link] [comments]  |
| Posted: 14 Feb 2018 11:15 AM PST Some images show the neutrons seprating the protons and some show the protons and neutrons side by side. Here are links to the two most common depictions. https://upload.wikimedia.org/wikipedia/commons/thumb/7/79/Alpha_Decay.svg/1200px-Alpha_Decay.svg.png [link] [comments]  |
| Posted: 14 Feb 2018 10:52 AM PST It's hard to imagine exponentiation, logs, and roots as continuous operators, but clearly they must be. Is it possible to get units this weird? And what would they mean? [link] [comments]  |
