woah

did SE change the site font or something

Wow, you can tell a book is physics/applied when they used the word 'fudge' to describe a method to make an analytical solution possible.

What am I reading

well......at least they're upfront about it

Hi All..

In thermodynamics. Work is inexact differential due to path dependence and pressure is depend on volume and temperature.

What if we take isothermal process. or pressure is only depend on change in volume. Does work become exact differential???

@123 That's not really a meaningful question - processes are just specific paths through thermodynamic state space, and it makes no sense mathematically to ask whether a differential is exact only for a specific path.

@ACuriousMind Oookay... Thanks

Hey everyone

I have a quick question. Can you see the image created by projector with your bare eyes?

If you can, where you should be standing with respect to projector?

@SirCumference if you look into the "featured on meta" box on the main site, you should see a post announcing exactly that

@M.ÇağlarTUFAN standing directly in front of the projector and staring into the lens would probably be the best place

depends on the lens and projector'
