If you solve the Navier Stokes equations, you'll give a couple interviews at some local media and then keep working in other problems. The director of your lab will not make a career for himself talking about your achievment.
Some exposure is of course necessary, but when it becomes the main driving force it turns ridiculous.
If I solve the navier stokes equations or whatever, but never talk about it... Yeah. Who would know. How could they know?
Tree, woods, sound.
