Fragen über die Beispielsätze mit, und die Definition und Benutzung von "Albert"

A: I think some commas would help, but you are right that there’s a bit missing off the main clause 😆 so it’s not a complete sentence as it is.

If the main clause is “Albert Einstein was a man” then “one of the greatest minds of all times”, “who rocked the world with his theory of relativity” and “to change our understanding of the universe” are all clauses which add extra info.

You could therefore have this:
Albert Einstein, one of the greatest minds of all times, who rocked the world with his theory of relativity, to change our understanding of the universe, was a man.

Or this:

Albert Einstein, one of the greatest minds of all times, who rocked the world with his theory of relativity, changed our understanding of the universe.
(So the main clause is: Albert Einstein changed our understanding of the universe)

A: It means that Albert works in an office. He was at the office where he works, and he came home.

A: The quote means; You're wasting your time trying too hard to get a different result if you're doing the same thing - It would better to start something to start a new idea

A: Albert Einstein thought, "Studying hard is...." Direct discourse."
Albert Einstein thought that studying hard was .... "Indirect discourse"

A: You can use both present and past tense here to mean the same thing.

I’d say

Albert Einstein thought studying hard IS / WAS the key TO being successful.

A: It's a matter of tense. If Albert Einstein were still alive, you could say : Albert Einstein thinks studying hard is---.
But as he is long dead, you use the past tense : Albert Einstein thought studying hard was----.

A: No, they don't have the same meaning because the verb 'is' is present tense and the verb 'was' is past tense, so when talking about the dead you use past tense verbs like 'was' and when talking about the living you use present tense verbs like 'is'

A: Albert Einstein *was* a great physicist.

Albert Einstein is dead, so you have to say he was a great physicist, not he is a great physicist.
"Physicist" is a countable noun so you have to say "a great physicist".
"Physicist" is singular; "physicists" is plural.

A: Do you know the name of Albert Speer? He was a Nazi minister and architect who opposed Hitler's final plan to destroy Germany, and escaped a death sentence at the Nuremberg trials. Today, I watched a TV show that introduced him, and became interested in his story. I thought the Nazi leaders were all as terrible as Himmler, but that wasn't true.

A: × It was about a very advanced mathematics for that time.
✓ It was very advanced mathematics for the time.

× He continued to study it patiently, wondering what kind of creature would emerge if he threw his beloved son, E=mc^2, into that boiling pot of that mathematics called Riemannian geometry.
✓ He continued to study it patiently, wondering what kind of creature would emerge if he threw his beloved son, E=mc^2, into that boiling pot of mathematics called Riemannian geometry.

This passage is generally well-written. It reads as more poetic than formal. You should consider "Einstein" instead of "Albert", unless the passage is written from the perspective of someone who was personally familiar with Albert Einstein. In English, it is more common to use the family name or full name when referring to famous individuals.

A: Albert Einstein
