Making mobile and tablet view a scaled version of desktop view

I have some two-column posts on my website that just don’t look good in responsive mode (puts them in one column format). I disabled the theme’s mobile and tablet view for those posts but the result doesn’t look good.

This is an example: https://www.open-stem.org/partial-differential-equations-modeling-the-world-we-live-in/

It looks great on desktop (at least on mine). On mobile view with responsive mode off, it looks like this: https://i58.tinypic.com/n20jdk.png Tablet view is very similar

There’s tons of empty space below the pictures in each column due to the scaling that happens on mobile.

Is there any elegant solution to this problem (apart from formatting all the articles differently..)? If not, is there anyway to just serve the desktop version exactly as it is on mobile/tablet devices?
