You flunked two semesters of community college? If I'm reading that right, that's not a good sign of potential success at this time. It may be a sign that you are just not ready for pursuing a college/university degree yet. What kind of part-time work are you doing? Have you ever done any...

Can you elaborate? Do you mean photolithography used in IC fabrication?

What is that thing on Messi's shoe? This was from the great game yesterday versus Cape Verde.

I was at a photonics trade show many years ago, and as I walked down one of the aisles, I heard a "snap, snap" noise every few seconds. As I got closer, I saw that it was a large laser (about the size of a small car, including the power source), and they had it set up to focus the pulsing beam...

@Josiah -- Please take care not to try to reopen a closed thread. Your previous thread on this question was closed because you veered off into non-physical territory with your laser power questions. I will let this thread here proceed, but only if you stick to known Physics. Here is how your...

Huh, I think you're right. So they just created a plasma pulsing between their mirrors and then pulled energy back out of the pulses? Sheesh, what a buzz-kill. I've been looking for a technical explanation of what they did in this experiment (compared to their fusion articles that I've...

For at least 4 reasons the OP is no longer with us, so this thread is closed.

There are two different types of people in the world: those who can fill in the blanks to complete sentences, and those who cannot... :wink: When you asked ChatGPT this question, what was the response? :wink:

I looked through their website a couple months ago and was reasonably impressed with their technology. I forget if I visited their website because of something on PF or maybe on Facebook. The mechanical design and fabrication are pretty impressive, since the reactor needs to withstand very...

How is this different from your previous thread?

Fixed that for you. Welcome to PF, but please be sure to translate your posts into English. Thanks. :smile:
