How did LizardSquad take down (See list in text) At the same time, right now ? | Where did you hear lizard squad took claim for the outage? I thought it was just the storm that hit some data center.They employ a very large network of infected routers across the globe, leveraged together it's unlikely any service could immediately stay online until the operations on the network side began null routi... |
why do we think so differently even if our brains are practically the same? | Our brains are all made of the same things but how we think depends on our genetics and environment. Imagine giving raw materials for a teddy bear to 1,000 people on Etsy who make stuffed animals. Everyone starts with the same materials but each completed bear will be slightly different. Some people will hand sew each ... |
Why do people black out when drinking? | Well, quite simply put alcohol is poison, and as such it has some negative effects on your body. To be spesific, there is a part of your brain called the hippocampus, that is the part of the brain that is responsible for learning and memory. It uses a metal called Zinc to do this. Zinc is also known as spelter. Alcohol... |
What is the difference between Martial Law and National Emergency? | In what country? Given you're mentioning a parliament we can't even make the usual Reddit assumption you're an American and given there's a huge collection of entirely distinct and sovereign states with parliaments we can't assume you mean any particular country. Law varies enough we can't say anything in general about... |
How do Catalytic reactions work? | Here's a good example of a catalyst: You are sitting on a decaying rope bridge that will eventually give under your own weight after a few minutes. Somebody could "catalyze" your fall by cutting the rope bridge with a saw, causing you to fall prematurely. If the "reaction" is you falling, the saw would be the catalyst.... |
What's the difference in flying a space ship or a fighter jet? | **TL;DR: Jets need to take into account air physics, spaceships need to take into account gravity physics.** Fighter jet is in the atmosphere and thus relies on using the air for lift. A pilot would need to be aware of the fluid physics that comes with each interaction with the plane, such as how to lower and raise the... |
How did the HMS Challenger find Challenger Deep in 1875 without access to submersibles or sonar? | A very long string, with a lump of lead on the end. No - really. Though rope, of course, rather than string. A big lump of lead on the end - the line goes slack when it reaches the bottom. Grease pressed into the hollow end of the cup could sample the bottom. |
After doing a demanding cardiovascular exercise, my tongue tastes like blood. Why is that? | When you exercise very hard in a way that works your heart and lungs, you increase your blood pressure. This pushes more fluid into your lungs than they can handle. When this happens during a heart attack, it is called "pulmonary edema", which is very serious and life threatening. You are experiencing mild pulmonary ed... |
Why do human children create such a big fuss about eating food, while their counterparts in the rest of the animal kingdom don't display similarly recalcitrant behaviour? | They're the only ones being told to eat at a particular time and place, regardless of how they are feeling or of what else is currently holding their interest. Occurring before they've been trained to accept these conditions, is enough to make anyone as surly as a leech on a corpse.How do you mean? Make a fuss about ea... |
why are there no 'big' dogs, only cats? | Because they are pack hunters, and therefore don't have an evolutionary benefit from increased size. Feline species usually hunt alone, and therefore have an advantage if they are giant sabletoothed monsters. You should also keep in mind that chihuahuas and basically every dog 'kind' you see we not evolved that way, we... |
