[Grammar] If clause - might not/might have/would not be

[Kumar Nadimuthu]

1. If Aryabhata hadn't invented zero, our greatest scientists Newton and Albert Einstein might not be succeeded.
2. If Aryabhata doesn't invent zero, some other mathematician might have invented.
3. If zero not invented, our present technology would not be developed upto this mark.

Are the above sentences grammatically correct?

 

[emsr2d2]

They are not correct.

If Aryabhata had not invented zero, Newton and Einstein might not have succeeded.
If Aryabhata had not invented zero, another mathematician might have invented it.
If zero had not been invented, technology would not be where it is today.

(Note that I know nothing about maths or the "invention" of zero so I have only been able to make the sentences grammatically correct. I have no idea if they are true.)

 

[MikeNewYork]

I don't know who invented the concept of zero, but it was very important. It was significant that we went from 1 BC to 1 AD in one year.

 

[Kumar Nadimuthu]

If Aryabhata had not invented zero, Newton and Einstein might not have succeeded.

If I omit Einstein in the above sentence, Can I use "might not be"?

If Aryabhata had not invented zero, Newton might not be succeeded.

 

[Rover_KE]

No. That does not make sense.

(In reality, I don't believe it's clear who actually first postulated (rather than invented) the concept of zero, but I'm fairly sure that if he hadn't, somebody else would have done long before Newton and Einstein started work.)

 

[Matthew Wai]

Newton might not be succeeded.

'Succeed' should be an intransitive verb here, so the passive voice is not possible.

[emsr2d2]

We don't say "XXX is succeeded" in this context.

Newton succeeds ...
Newton succeeded ...
Newton has succeeded ...
Newton had succeeded ...
Newton will succeed ...



For your information, "to succeed" has another meaning which can be used in the way you suggested. When a monarch leaves the throne (dies or abdicates) and a new monarch takes their place, we say, for example "King George VI was succeeded by Queen Elizabeth II". Here, it means "replaced by". She took over as monarch. When she dies/abdicates, it will be Prince Charles' turn (if he wants it). She will be succeeded by him. There is a distinct order in which people are entitled to take the throne and that is called the "Order of Succession". Prince Charles is, currently, first in line to the throne because he is the oldest son of the current monarch.
That sentence can also be constructed as "Queen Elizabeth II succeeded King George VI".

 

[Matthew Wai]

Newton might not be succeeded.

'Newton might not have been successful' might be possible in this context.
