Why does green mean go while red means stop? Who decided this small thing that has had a huge impact on our view of these colors?

While watching the weather today I noticed all the green means "light weather" while the red stuff is more severe.. This got me thinking about how we always associate green with "good, go, success, positive, ect" and red is just the opposite. Same thing with traffic lights! Does anyone know why this is?

Thanks!

During the first World War, why didn't Great Britain ever attempt an amphibious operation somewhere along the Baltic coast behind German lines?

Great Britain had one if the world's most powerful navies during the Great War, so why didn't they ever attempt a landing of some kind behind the German lines instead of keeping their attention focused on the trenches of the Western Front?

What was the general opinion on Nietzsche's work when it was first published?

I'm writing a book that takes place in 1893, and I want one of the more scholarly characters to be familiar with Nietzsche, who had been publishing very recently. But I also want to be accurate with how his works were perceived at the time, since there's a lot of baggage with him and Nihilism in the modern zeitgeist. What was the general reaction to his writing in the time period when it was published?

During the revolutionary war what would "Captain of the top" mean if you were on an American naval ship?

I was reading about some of my families founding members and I came across a text which uses the term "Captain of the top". The man they are referring to would only have been 14 or 15 years old so it may just be an honorary type title? Or was it an actual position?

Here is the text its from:

"On returning to England, he enlisted on board the King's ship bound to the Island of Jamaica with a cargo of military stores. This voyage completed, he again enlisted on an English man-of- war vessel, and, with that vessel, was captured by the American ship Black Prince, commanded by Richard Crowminshield. He and his shipmates were confined in irons and nearly devoured l)y lice. On application to the commodore, who was moved with sympathy for the youth, his shackles were removed and permis- sion given him to mingle and labor with the sailors of the Black Prince who manned the captured man-of-war vessel and took her into an American port (presumably Boston), where they landed in May, 1778. The succeeding fall, this vessel was impressed into the American service, sent to the Maine coast to aid in driv- ing the British from the Penobscot, and young Francis, having sworn allegiance to the cause of America, acted in the capacity of "captain of the top" in the engagement at Castine that soon followed, in which this vessel was an active participant."

What happened to the abortion debate in the US in 1996?

I watched this clip from John Oliver's Last Week Tonight a few days ago and was surprised at just how many people seem to be against abortions in the US, so I went searching for numbers. I came across this page from Gallup which shows historical trends in the US abortion debate.

It appears that in 1996 the number of people identifying as "pro-life" rose dramatically while the number of people identifying as "pro-choice" decreased. This is such a large shift in a single year, that I assume something must have triggered it. What happened in 1996?

Conventional wisdom is that a cavalry charge into a line of pikemen or pole-arms was suicidal. Are there notable counter-examples, and why were they different?

And, an implicit question: to what extent is there historical basis for the "conventional wisdom" I mentioned before? Was it a handful of paradigmatic cases that established this rule of thumb or was it numerous, smaller-scale lessons that eventually led to this?

Thanks in advance, r/AskHistorians! :)

Why don't Christians celebrate Easter 3 days after Passover?

In the Bible, Jesus celebrates Passover with his disciples, gets betrayed by Judas, arrested, put on trial, crucified, and rises again on the third day (Easter Sunday). Going by when Passover is celebrated, why did we celebrate Easter last weekend when Passover is on April 22nd this year? Why don't Christians celebrate Easter 3 days after Passover every year? I mean, it doesn't make chronological sense.

Standardized Testing and anti-Semitism

I was reading [this article] (http://www.theatlantic.com/education/archive/2016/03/college-admissions-narcissists/475722/) yesterday, and at one point the author states: "In the early 20th century, as I recounted in part one, the big motivation to look beyond standardized-test scores was to stem the influx of Jewish students." I found this pretty interesting, but part one of the article didn't give any more information.

After doing a bit more research, I found a few more articles that make the same assertion, but don't offer any historical background to it.

So my question is: what's the history behind using standardized testing as a tool of limiting Jewish students to Universities?

Who really won the Cold War?

I feel like we, as Americans, always say we won the Cold War. However, when was the last time we sent a manned mission to space?

Ronald Reagan never claimed to have bested the Soviet Union and/or won the Cold War.

In the last few years, we've seen Russia annex the Crimea with little to no repercussions, taking land from another sovereign state against the signed 1954 decree that legally transferred the land to Ukraine. No one interfered.

So I was wondering, who do you think really "won" the Cold War?

**I realize the Crimea part falls within the 20 year rule, but I am looking for responses that fall outside the scope of the 20 years.
