Did You Get a BA or a BS in Physics?

I’m seeing some people online say it does matter to employers, and others that it doesn’t matter.

Both have pros and cons.

Some schools only offer a BA.

Some schools offer both, and the BS requires more work.

All this to say, I’m still confused. I’d figure I’d ask you guys out there what your personal experience regarding this topic is. How important is it to have either degree? Is contemplating which one to pursue important at all? And finally, how has your or your friend’s/colleague’s career and trajectory been overall, and how much do you attribute that to the letters in the degree?

Thanks.

Electron lithography with old crt tv

I was interested by Sam Zeloof's photolithography machine that uses a projector strapped to a microscope for maskless photolithography. This made me have an idea: using the electron gun of an old crt tv for the same purpose (using an adequate resist that is) inside a vacuum tube of some sorts.

How achievable is this? And would the electron gun be precise enough to reach micron level of precision, and if so what modification would it need?

Also would it be easier calibrating the electron gun rather than the optics needed for Zeloof's design?
