Are both of these correct?

What does it mean when I use present tense?
1. He must have had a great big laugh when he came up with the idea of having the entire heat of the computer's processor being adsorbed into the person's legs as they sit and use it.

What does it mean when I use past tense?
2. He must have had a great big laugh when he came up with the idea of having the entire heat of the computer's processor being adsorbed into the person's legs as they sat and used  it.

Thanks.

Hi Jack,

They are both correct.

#1 suggests to me that people are still doing this (ie sitting and absorbing) today.

#2 does not make any suggestion about this. Maybe they are doing this today, maybe not.

Best wishes, Clive

For beginners, is #2 a better sentence because sentences should be either all past tense or all present tense?

Also is #2 referring to the time when he thought about it, thus all past tense?

Thanks.

Hi Jack,

For beginners, is #2 a better sentence because sentences should be either all past tense or all present tense? I don't think it's good to think this way about tenses. eg I studied history last year but next year I will study math. This is one sentence, with two tenses, and it's fine and normal.

Also is #2 referring to the time when he thought about it, thus all past tense? Yes, you can think of it that way.

Best wishes, Clive

In January, 2007 ownership decided that the cost of repairing the roof was too high, and instead plan to demolish the structure and redevelop the site. (I got this off an article. Is 'plan' supposed to be 'plans'? What is the subject for 'plan' ?)

The ownership is being regarded as a group of owners, so the owners plan to demolish the structure.  They plan ...
