It's one of the only ones they might listen to. If you say "what you're doing is morally wrong", they'll just say "no it isn't, what you're doing is morally wrong."

If you say "what you're doing is impoverishing your nation and hurting everyone you care about", they might actually take some action.

No. The reason it's happening is that Earth's rotation is faster than the Moon's orbit - a day is shorter than a month.

Because of this, the Moon is leeching kinetic energy from Earth's rotation to orbit faster (drifting further away is simply a consequence of orbiting faster). This speeds up the Moon's orbit at the cost of slowing the Earth's rotation. Over time this energy-leeching will stabilize once the Moon has sped up so much, and the Earth has slowed down so much, that the Moon's orbit and the Earth's rotation will take the exact same amount of time - a day will be equal to a month - and the Moon will appear motionless in the sky. This is called tidal locking.

But as other comments have stated, this process will take so long that the Sun will kill us all long before it finishes.

The city manager didn't cause the power outages. The outages were caused because of a combination of an ice storm that froze all the trees, and high winds that snapped the frozen branches. Tens of thousands of trees, tree limbs, and tree branches fell all over the city, and many of them damaged power lines as they fell.

What the city manager was responsible for was the cleanup and repair after the storm was over. It took over two weeks to restore power to everybody, and people are accusing the city manager of not organizing the repair crews properly.

The Latin word in the saying is audentes, meaning "audacious", "daring", or "risky". The modern English usage of "bold" fits pretty well as a translation.

It was supposed to be the last book. The plan was for 6 books on Odyssey 2: Aquatic Boogaloo and then 6 books on Iliad 2: the Italyad.

The Aeneid is mostly finished. There are scenes missing here and there, and it should have more fleshed-out of an ending than "He killed the bad guy. The end." But for the most part Virgil was able to tell the story he wanted to tell.

Woman was originally spelled wifmann, from wif meaning "female" and mann meaning "person". The f eventually became an m, making wimmann.

Wif was pronounced "weef". The "ee" vowel is pronounced close to the front of the mouth. Over the centuries, the pronunciation of wimman changed, the vowel moving farther back in the mouth from an "ee" to an "ih" (as in "little"), then farther back to an "ooh" (as in "book").

The reason it's not pronounced with an "aww" (as in "yawn") or an "ahh" (as in "thought") is that these vowels are made even farther back in the mouth, close to the throat. They're also made with the mouth farther open than "ee", "ih", or "ooh". The vowel may have drifted from "ee" over the centuries, but it did not drift far enough to reach "ahh".

You're assuming they were doing this against their will. From what I remember the last time this case made headlines, this was one of those guys with crazy amounts of charisma; he basically brainwashed them all into his own personal sex cult. Like a modern day Charlie Manson.

Reposting an old comment of mine about the Greeks and heliocentrism:

> They "figured it out" but couldn't prove it. The hypothesis had three main issues that weren't solved until scientific knowledge caught up with astronomy:

> 1) Parallax. If the Earth moves around the Sun, then the stars should appear to move back and forth every six months, the same way that a stationary object appears to move when you move your head side-to-side. In fact the stars do show this behavior, but because they're so far away, it's unnoticeable without a telescope. The ancient Greeks believed the stars to be relatively close to Earth, so the parallax should've been much more apparent. Accepting heliocentrism would've meant accepting that the universe was far larger than they thought - they weren't ready to accept that.

> 2) Inertia. The ancient Greeks did not believe that an object in motion will remain in motion. They believed in the concepts of natural motion and disturbed motion, which, among other ideas, posited that force was proportional to velocity. So if the Earth is moving, why do flying birds not slow down and get left behind?

> 3) How can the Earth move? Again, this comes down to the ancient idea of natural motion. In their system of natural philosophy, heavy objects naturally fall to the ground. A heavy object in motion slows down and stops. Earth is the heaviest thing there is - it is literally the element of heaviness. So how can it be in motion? What force is moving the Earth?

> For these reasons heliocentrism was abandoned for 1500 years. It wasn't sacrilegious or anything; it was just deemed to be an interesting hypothesis that didn't stand up to scrutiny.

Aristarchus of Samos was not burned at the stake.

You're thinking of Giordano Bruno, who lived 1800 years after Aristarchus. Bruno was burned at the stake, not just because he believed the Earth orbited the Sun, but because he believed that the universe was infinite, with countless other gods, and that Jesus was a malicious con man who deceived humanity into thinking there was only one god.

Sorry. The traditional textbook answer is that no, it's not possible after childhood.

However, there's a blurb on the wikipedia page that says that may be outdated knowledge. There is tentative evidence that it might be possible. If I were you, I'd look into the linked sources on that wiki page and talk to your doctor about your options.

Depends on the semantics of "blind". The eye doesn't just completely turn off, but it will have severely decreased vision, and the person may only perceive stuff with it when the good eye is closed.

Brain science is still new and not fully understood, but there are groups of neurons in the brain called ocular dominance columns that light up when one eye or the other is stimulated. In most people there are equal numbers of ocular columns for each eye. But in brains that had a bad eye during infancy, most of the ocular columns will be linked to the good eye. In other words, the brain literally rewires itself to be essentially one-eyed.

You know that machine the eye doctor makes you look into when you first start an eye exam? You look at a little circle with a picture in it (e.g. a picture of a hot air balloon), and the machine goes whrrrr whrrrr while the picture goes in and out of focus?

That's called an autorefractor, and it's able to (mostly) figure out how bad your eyes are all by itself. All the "which looks better, 1 or 2?" stuff afterwards is just fine-tuning the prescription from a starting point that the machine figured out.

So with babies, they can't do the fine-tuning part of the exam, but they can still look into an autorefractor.

This is actually very important for babies. The fine-tuning isn't super important, but if the baby has a very different prescription in one eye than the other, then the baby will start favoring their good eye at the expense of their bad eye. Their brain, as it grows, will literally stop paying attention to their bad eye. If it's not corrected in time, it can cause lifelong vision impairment in the bad eye.
