how can people just tell which direction they're going?
Well, there are a few ways. But most importantly, road signs should tell you which direction highways go. Also, it's all about learning how to orient yourself. Use the sun as a guide. It rises in the East and sets in the West. Looking into the sun in the morning? You're headed East. Sun to your left in the evening? You...

How crucial was the Army's role is the pacific campaign?
The bulk of the troops in the Pacific were actually Army, not USMC. By my count 22 Army divisions saw combat in the Pacific: Americal, Philippine, 6th, 7th, 24th, 25th, 27th, 31st, 32nd, 33rd, 37th, 38th, 40th, 41st, 43rd, 77th, 81st, 93rd, 96th, 98th, 11th Airborne, and 1st Cavalry.

Why is there things like depression that make people constantly sad but no disorders that cause constant euphoria?
Academic psychiatrist here. First off, depression doesn't "make" people sad. Rather "depression" is a description of a person's experience. It is often used to describe the symptom of depression, but there are broader clinical entities such as a "major depressive episode," which have operationalized definitions. As fo...

During the Battle of Moscow (1941), the Soviet Union moved a big amount of units from Siberia and the Far East to fight in Moscow. Couldn't it has been a good moment to start a second front in the east by the Japanese Empire?
Absolutely not Japan was in no condition to start another war with Russia as it was already moving to strike at the US and European Pacific colonies. By the start of Battle of Moscow, Japan was planning its attack on the US and to wipe out the Pacific Fleet. Japan was by this time starved of resources, the US, UK, and ...

Why do cast iron frying pans turn black?
It's mostly from iron oxide (FeO) forming due to reaction with oxygen in air. The oxide is normally a dark grey colour but even a tiny amount of absorbed oil will turn it dark black.

why is it so universally accepted that dinosaurs roared? is there any way paleontologist know what kind of sounds that actually would have made?
Paleontologists can use the features, shapes, and dimensions of the nasal cavities and other parts of the skull to determine what kinds of sounds dinosaurs might be able to make. In recent decades, we have found mummified dinosaurs with enough fossilized soft tissue to help with this kind of investigation. In the case...

As a segment of the population, did European nobility in the Medieval, Early Modern and Modern eras die disproportionately in war?
Yes, at least in many instances. I know that David Cannadine has demonstrated that WWI took a disproportionate human toll on the British aristocracy. I know his purpose in relating that is to make the point that even as late as 1914 the aristocracy were still committed to a warrior class ideal and that this ideal's e...

If living bodies are constantly emitting heat, are they losing minute amounts of mass?
Even if you assume that all of the energy is coming from converting matter into energy (a la E = m * c^2 ), it'd be a really, really small amount. Assuming a basal metabolic rate of 100 W, that yields 100 / (2.998 * 10^8 )^2 = 1.11265006 * 10^-15 kilograms every second. At that rate, you'd lose about 2.8 milligrams ...
[ "Based on the preceding work on electromagnetic mass, Friedrich Hasenöhrl suggested that part of the mass of a body (which he called apparent mass) can be thought of as radiation bouncing around a cavity. The \"apparent mass\" of radiation depends on the temperature (because every heated body emits radiation) and i...
Why did we evolve two kidneys?
This question is misleading because the question of "Why did we evolve X" is quite different from "What is the advantage of X"? The question of why we evolved something is answered in all cases by "because of mutation." We gain adaptive and maladaptive genotypes (which manifest as phenotypes like two kidneys) as a resu...

What causes electrons to move (and also eventually slow) in a current?
At a finite temperature, free electrons are always moving due to pure thermal motion. This doesn't give rise to any current because the electrons are moving in random directions, and their net motion cancels to zero. When an electric field exists across the material, it creates regions of high and low electric potenti...
[ "By controlling the accelerating voltage, the speed of the electrons flowing down the tube is set to be similar to the speed of the RF signal running down the helix. The signal in the wire causes a magnetic field to be induced in the center of the helix, where the electrons are flowing. Depending on the phase of th...
how can something like beer, a liquid, make you more thirsty?
Just because it's a liquid doesn't mean it'll provide you with water. Drink a bottle of mercury or antifreeze...... actually don't. Beer is a solution of alcohol and water. While it initially provides you with water, the alcohol triggers your system to use it's water store to flush out the processed alcohol toxin, l...

Did East Berliners dig tunnels to bypass the Berlin Wall during the Cold War?
Yes, they did. Before I dive deeper let me just clarify that it was not the Soviets who were responsible for securing the border of East Germany, but the Ministry of National Defense of the GDR. In fact the so called "Grenztruppen" (border troops) were an independent branch within the military of East Germany. The Ger...

Student and future astronaut Reinhard Furrer was among the West German escape helpers who assisted the East Berliners in escaping. During the escape, East German bord...
why does a hard boiled egg leave me feeling full much sooner than eating a srambled or fried egg?
It has a lot to do with the fact that more of the egg protein gets denatured when frying as opposed to boiling. Remember, your body has a lower tolerance for protein than fat, so will more quickly fill up on it. This is why people on high-protein diets can eat less and still feel full. The higher temps also break down ...

If you were a human floating towards the sun, at what distance from the sun would you feel an Earth-like temperature?
tl;dr: If you're near Earth's orbit, you're already way too close. You'd need to drift outward quite a bit. On Earth, if you leave something lying in the sun indefinitely, it will heat up until the heat it loses to the surrounding air (and the ground) is balanced with the heat it absorbs from the sun. In space, it wo...

Why can't we achieve the equivalent of a quantum computer simply by creating transistors with more than two states?
There is a big difference between an object that can exist in multiple states and an object that can exist in a superposition of states. A classical bit (0 or 1) or trit (0, 1 or 2) can still only exist in 2 (or 3) states. Its in the state 0, 1 or 2. A qbit exists in a superposition a|0 > + b|1 > , where "a" and "b" a...

The states that form a qubit in this protocol are the one-photon states of two modes, i.e. the states |01\n", "I...
why is it preferable to have illegally obtained evidence thrown out of court as opposed to keeping it and prosecuting the one who obtained it?
The Supreme Court discusses this rationale in every exclusionary case. The first thing to keep in mind is that the Constitution does not require an exclusionary rule. But for the 4th Amendment to have any value it must have some remedy or mechanism of enforcement. Suing the officials for an illegal search is always...

Is there any scientific basis behind the concept of "detoxing"?
No. The human body is quite capable of removing most toxins itself and none of these products have been shown to have any real effect in removing "toxins."
[ "Detoxification (often shortened to detox and sometimes called body cleansing) is a type of alternative-medicine treatment which aims to rid the body of unspecified \"toxins\" – substances that proponents claim have accumulated in the body and have undesirable short-term or long-term effects on individual health.

When did Mexico become a majority Spanish-speaking country (as opposed to the various indigenous languages). I thought I'd read somewhere that in the 1820s, when independence was achieved, ~50% of the country still primarily spoke an Indian language
The following is sourced from Nicholas Ostler's *Empires of the Word: A Language History of the World.* When the Spanish conquered the territory we today (and many of its pre-conquest inhabitants) call Mexico, its people spoke a wide range of languages. Most common was Nahuatl, the Aztec language, which Ostler argues ...

Why is the speed of light expressed as 'c'?
It was once a common letter to use for the speed or velocity of various things, from Latin *celeritas*, "speed". Enough of the founding papers on relativity used it for the invariant speed that it's become rare to see it used in any other sense.
[ "where \"c\" is the speed of light, with some authors preferring to multiply the right hand side by an overall constant formula_2, where \"ε\" is the permittivity of free space.

how are the stars always in the same spot in the sky?
First, stars are really, really far away. So from our perspective it looks like they're in the same place every night... But that's not true.

Why is lithium the best element to use for batteries?
This may be a shorter answer than you wanted but in summary: you want a very light, highly reactive metal. The Most reactive metals are at the very left of the periodic table. The lightest ones are at the very top. Lithium is the top-left-most metal. The only lighter elements are hydrogen and helium. And the only more ...
[ "Lithium is the metal with lowest density and with the greatest electrochemical potential and energy-to-weight ratio. The low atomic weight and small size of its ions also speeds its diffusion, suggesting that it would make an ideal material for batteries.

Was Champagne or Beer historically carbonated ? If you went back in time, what would these taste like ?
Carbon dioxide production is a byproduct of the yeast that ferments sugar to alcohol. Soft drinks are carbonated by adding CO2 under pressure, but for an alcoholic drink it's enough that it's fermented in a closed container. The in-bottle fermentation that gives champagne its carbonation is what set it apart from other...

why do advertisers & marketing people believe it's a good strategy to make ads that are deliberately annoying, and to run them several times in a row during a commercial break?
We are all familiar with those ads on television that just scream at us to switch them off. They are just so excruciating that you can’t bear to watch them.

Is there a book that retells U.S. History in an unbiased, completely truthful way?
I don't think that you will be able to get what you're looking for in less than 300 pages. That book would fall into pitfalls similar to the pitfalls of textbooks; they can't cover everything or give in depth coverage to the most important parts without cutting some peoples, places, and events.

When you lose fat in your body, are you breathing out the carbons or are do you urinate the carbons?
You breathe out the carbons. Fat breaks down into ketone bodies like actylacetate and beta-hydroxybutarate, which is transported to our cells and made into acetyl-CoA, which then enters the TCA cycle, producing CO2, which is then transported to your lungs.
