Stars and Visibility | [
"It's a quirk of the human eye. At the center of the eye (the fovea) we mostly have colour-sensitive cone cells to see detail and colour of what we're focusing on. Around the fovea we mostly have rod cells that can't see colour but are more sensitive to variations in light intensity and movement. \nLooking slightl... | [

What are good and bad sides of manual and automatic drive gear? | [
"Automatics weigh more, so that alone makes gas mileage worse. They are also more complicated, so that means reliability is going to be lower. It is easier to operate, which may free up your attention for focus on what is *outside* the car.\n\nSome people derive satisfaction from shifting, and flexibility in usin... | [
"amount of true manual control provided is highly variable: some systems will override the driver's selections under certain conditions, generally in the interest of preventing engine damage. Since these gearboxes also have a throttle kickdown switch, it is impossible to fully exploit the engine power at low to med... |
the special and general theory of relativity | [
"We know that light moves at the speed *c* (roughly 300000km/s).\n\nSo here's a question for you (that Einstein asked himself): what would you see if you sat on a beam of light and looked into the mirror? Would your reflection disappear? Would it be normal?\n\nHe then thought: what's the speed of light relative to ... | [
"Relativity: The Special and the General Theory Relativity: The Special and the General Theory began as a short paper and was eventually published as a book written by Albert Einstein with the aim of giving:\n. . . an exact insight into the theory of relativity to those readers who, from a general scientific and ph... |
How do muscles grow? | [
"I hope this answer qualifies as technical, yet simple enough (as I very rarely post here), but the basic idea that I understand is that your muscles rip and tear on a microscopic level when you are working out, and the harder you push those muscles, the more they rip. Hence where the idea comes from that more reps... | [
"Muscle Structure The anatomy of muscles includes gross anatomy, which comprises all the muscles of an organism, and microanatomy, which comprises the structures of a single muscle. Microanatomy Skeletal muscles are sheathed by a tough layer of connective tissue called the epimysium. The epimysium anchors muscle ti... |
What is the role of actual real-life actors in making animated characters? Like Liam Neeson playing Aslan in Narnia? | [
"Could you elaborate your question?\n\nThey are voice actors. They sit in a studio and record their lines.
