Countries like to make sure you can support yourself independently when visiting, and have a way to get back home.

Probably to ensure that you actually have funds available to cover expenses, otherwise folks might just show up and run out of cash then not have a way to get home

It started with the Jewish diaspora under the ancient Romans. After a series of Jewish revolts against Roman rule, Jews were not allowed to settle or worship in Jerusalem for 500 years. Only when the Muslims took Jerusalem were Jews invited back, but they were not given political power.

As a result Jews formed communities elsewhere in the Roman Empire. When Christianity became the official religion of the Roman and Byzantine empires, it created a tense relationship with Jews. The same was true in the Muslim empire. Throughout the Middle Ages, at times Jews were tolerated, and at other times they were persecuted.

Since they were often not allowed to own land, and their existence in any particular land was always subject to change, many Jews formed international relationships with fellow Jews in other countries, and took advantage of those relationships in trade and finance. This helped them survive and even thrive, but their success often made them even more of a target of discrimination.

They were, in short, a common and easily identified minority in every European and Middle Eastern country, at a time when there were few other minorities. There were some other minorities also subjected to discrimination. In fact, pretty much any outsider was suspicious. But none were more pervasive or visible than Jews. The fact that many were successful in business despite or even because of the discrimination just made the hatred directed at them more intense.

That remained the case in the 19th, 20th, and 21st centuries. Furthermore, as aristocrats lost power and capitalists gained power, it was convenient to deflect anger away from other capitalists by pointing the finger at wealthy Jews. That has continued to be the case throughout the West.

Of course, today there’s also the issue of the State of Israel, which has never really been accepted in the Muslim world. And Israel’s response to Muslim aggression has turned them into an occupying force that has been accused of human rights violations. In other words, in the one country run by Jews they treat Muslims as outsiders, and have been accused of unjustified discrimination against them. And since the U.S. backs Israel with massive military and economic aid, the U.S. is often blamed for Israel’s actions.

The digital ones are the same as the ones with the lines, they just use additional electronics to read the lines and give you the lcd output.

There are some digital tests now that say “pregnant” or “not pregnant” (and also some kind of digital ovulation tests - I think they flash a smiley face if you are ovulating).

They are more expensive, wasteful, and would have to be different in every language.

The way the test usually works is that it responds to a hormone you produce while pregnant. If that hormone is present, you will see two lines. If you’re not pregnant you will just see the control line. This is very rudimentary - making a test with a digital screen is a lot more complicated.

People who are actively trying to have a baby may take dozens of tests over that time. They usually buy a box of cheap tests that are literally just a tiny strip you dip in a cup of urine (as opposed to a big plastic one you can pee directly onto)

Google took the loss in ad revenue early on.

There's a bigger gap between dots and dashes in different letters. If a dot is 1 unit of time then a dash is 3. Dots and dashes in the same letter are separated by 1 unit whereas there's a 3-unit gap between letters and a 7-unit gap between words. With practice it's not hard to hear, even at relatively high speeds. You don't listen for the individual dots and dashes but instead you learn the rhythm of each letter and even common short words.

This is not true at all! Each Chinese character writes a word in a spoken language. Currently there are systems to use them for Mandarin and Cantonese, but mostly not for other Sinitic languages. The primary issue is that any given language may have words (including common grammatical function words) which have no clear appropriate character for them - either it's not clear which (if any) Middle Chinese word this word descends from, or it descends from the same word as another character, or there's some reason why speakers may find the character inappropriate for that word for other reasons (maybe it's developed a vulgar connotation in Mandarin, for example). Adapting Chinese characters to a new language, even if it's Sinitic, is not a straightforward process.

And of course, if you know how to write grammatical function words in Mandarin, that doesn't mean you'll recognise Cantonese's grammatical function words. Plus, many related words (which "should" be written with the same character) may have shifted their meaning - for example, 聞 meant 'hear' in Middle Chinese, and while both Mandarin and Cantonese have shifted it to 'smell', it remains 'hear' in its use in Japanese.

There are a few ideas. Anti-Semitism has been around for a long time.

One is that Judaism was one of the few religions that allowed money lending with interest. This was considered usury and prohibited in some other religions, namely Christianity and Islam. The idea being Jews would be money lenders, and would suffer the wrath of anyone who couldn't or didn't want to pay them back. In fact Jews sometimes played an important role in the economy of European powers, often they were prohibited from other trades. Leaders could tax/extort them or borrow money from them, bypassing rules on taxation or religious laws on lending. This could lead to persecution and expulsion, often without any real concern for their safety.

Ultimately they were a people without a nation or homeland. Humans aren't always the most welcoming of creatures, or the most fair. It's historically been easy to use Jews and other minorities as a scapegoat. We still see it today.

Keep in mind it's not really like today where we have minorities but they're at least ostensibly citizens with rights. Jews were often forced to live in ghettos, Jewish quarters or areas, or have identifying marks. There was no pretence, they were the other. It's not easy to break that sort of ingrained social structure.

I'm sure any Christian you asked might have had their reasons, but I think the fundamental reason, as depressing as it is, is simple: The Jews were often treated so poorly because they could be treated poorly, like any minority group. It was just their misfortune to always be a minority group.

In a way, the basic military logic that it's better to flank the enemy than attack head on is WHY the trenches extended from the North Sea to Switzerland. Commanders from each side kept attempting to flank one another in the traditional way but innovations in logistics meant that WWI was the first war fought where the armies numbered in the millions of men, so when they tried to maneuver around the side of an army like they'd been trained they just found more army.

They both kept going further and further with attempted flank after attempted flank until they both hit the metaphorical walls and then nobody really knew what do to next because they found themselves in a completely unprecedented military situation. Military theorists eventually figured out how to punch through a line with narrow concentration of force and flank that way, but it took bloody trial and error.

The pauses are of different lengths. How long a pause in between the dots and dashes depends if you are in a character (letter, digit, or other symbols), between characters, and between words. So if you learn it you will be able to tell the pauses apart

The timing is includes how long the dots and dashes are themself

• dot 1 unit
• dash 3 units
• Pause between dots and dashes within a character 1 unit.
• Pause between characters in a word 3 units.
• Pause between words 7 units

You can use a website like https://www.meridianoutpost.com/resources/etools/calculators/calculator-morse-code.php? and generate the sound, it is quite clear at low speed that it is different even for a novice. It is noticeable even at high speed that pauses are not identical even if you might not there the it exactly right.

A long cycle of, being seen as "others", being persecuted for being "others", rallying around each other because of persecution, being seen as "others" for rallying around each other, so on and so on for several thousand years.

And it can run doom!

> Or maybe it’s because their are 8 different dialects in Chinese and you were using one they didn’t understand!

There are in fact probably several hundred Sinitic languages (which are often interchangeably referred to as 'Chinese').

Firstly, Jews are a minority group in most countries. If you're a wannabe dictator (or an actual dictator), a tactic as old as civilization is to blame all of society's ills on some group of people who don't have the clout to defend themselves.

Secondly, Christianity. Since the earliest days of the religion, certain Christians have concluded that the Jewish people were responsible for Jesus' execution. If you believe that a group literally killed God, then you can justify doing horrible things.

Thirdly, more Christianity. In medieval Europe, Christians were forbidden from charging interest on loans. At the same time, Jews were often forbidden from owning land. Naturally, some Jews tried to make the best of a bad situation by becoming money lenders - people still needed loans, after all. But of course, if you suddenly find that you can't pay back your loan, then you're probably going to lash out at the person who gave you the loan in the first place.

Error Code 404

Like any language, if you are not used to hearing it, it sounds like jiberish. But once you learn it, it makes sense. There is a space between the dit and da in Morse code but at speed, you need a trained ear to hear it. Once you learn code, it is more like listening to music. Some words and phrases are repeated so often that it sounds like the entire word instead of each letter.

So experienced code guys can listen at 25 or 30 words per minute as well as transmit. It just takes alot of practice. I know these kind of guys and I'm an in pure amazement of what they can do. But they use it daily.
