"One solar day is the time it takes the planet to perform 1 full revolution on its axis. The real question should be why do planets revolve on their axis at different rates."

Why do "forgot my password" dialogs only allow you to change your password, not tell you what your current one is? | [
"If they're doing things right, they don't know your current password. When you set a password they put it through a \"hashing\" function and store the result. When you try to log in again, they put the password you entered through the same function and check if the result matches the one they have stored."

"1. They get the password. If you use the same password on multiple sites and one site gets hacked, the first thing the hackers will try doing when they get the passwords is attempt to log in with the same email+password on other websites. 2.

If whales breath air, why do they die when they 'beach' ? | [
"Whales' lungs and circulatory system have adapted to a buoyancy-neutral environment - a whale's body has the same overall density as the water around it. Out of water the effects of gravity collapse their organs and their hearts cannot pump blood efficiently. Blood pools in the lower part of their body and the res... | [
"They get it from the food that they eat. Whales, and dolphins, can't starve to death, they die of dehydration first. They do get a little bit from sea water but their kidneys can't remove much salt so if they accidentally drink too much sea water when they eat that could kill them."

Why is welded armor better than riveted armor? | [
"One of the top killers of crew members inside an armored vessel is [spalling](_URL_0_). Riveting two plates together means that there is essentially a metal pin holding to plates in place. Should an object (such as a tank shell) hit any of those rivets the force can turn the rivet into a projectile that bounces ar... | [
"The ribs make the can stronger without having to make it thicker. Those cans are under a lot of pressure when packing, vacuum sealing, being stacked, etc. A smooth can would dent or be crushed very easily. Even 55 gallon drums have a multiple ridges around them for the same reason."

Why would you make child car seat straps/webbing out of a material that you cannot wash by submerging the straps in water? | [
"As a parent who had been through more seats than I care to count, my guess would be... so you buy another one. While you can wash parts of most seats, the straps are generally not removable to wash (probably for safety reasons that could result from potential wear or unsafe installation of re-attached after remova... | [
"> How does plain, cold water compromise the integrity of a nylon belt?

Why can't a compiled computer program be dis-assembled into assembly language, then re-assembled on another OS? | [
"The short version is: When I write a program and compile it, the resulting assembly is *not* a complete list of everything the program needs to do. It is filled with lots of calls like \"ask the operating system where file X is\" \"ask the operating system to put the contents of file X in memory location Y\" \"as... | [
"Much of the difference isn't in the language itself, but in the tools that run that language. For example one language is designed to be *interpreted* by the computer at the last moment, while another is *compiled* (translated) into a faster form before the programmer releases it to users."

How does a leather strap sharpen a razor? | [
"> How can this possibly sharpen a metal blade? It doesn't sharpen it, it hones the blade. When you sharpen a blade the edge is made very thin. It is so thin that it is flexible, and can easily be curled over by use or even accidentally while sharpening. This makes what would otherwise be a sharp blade a bit blunt.... | [

To what extent can tissue be regenerated? | [
"It depends on the organ. As you noted, limbs will not regenerate, but bones will \"regenerate\" (kind of) if the pieces are brought back in proximity (assuming there is intact blood and nervous supplies).

Why are the holes inside set-squares rounded? | [

How is Amazon able to fulfill such a wide variety of different types of product orders in such a short time (Same Day, Next Day, etc.)? | [
