Washington has continued to be a circus, yes. The way to fix it isn't to hand power to the republicans. They just had it and it was as much a circus as ever. Personally, I've never had anyone request to directly buy my vote, republican, democrat, nor third party. But when each candidate is...

That's a weird back-and-forth. Anyway, 9 out of 10 Swiss vote by mail. Voting by mail is also common in the UK, Germany, Luxembourg, Austria, and Liechtenstein. But what you say is true about it being disallowed more often than allowed, mainly because it was disallowed in the Eastern Bloc and...

I agree that their rules apply/don't apply based on convenience, but this is true regardless of who is in power. I think that expecting the same level protection at the border and around the capitol is just setting your expectation up for failure. For example, the Russian border is quite...

Direct diode or DPSS? There are all sorts of crazy diode-based lasers out there in the lab world with crazy spec's, like multiple watts of single-mode TEM00 output, but who has $50k to find out? Ushio has this guy: http://www.ushio-optosemi.com/documents/uos/products/UOSE_DS_HL40071MG_Rev5.pdf...

If you guys don't believe in the vaccine, why mention whether or not illegal immigrants are vaccinated? If you believe Biden stole the 2020 election, what needs to be different in 2024 to ensure that it doesn't happen again? Is there a checklist of boxes that can be in place, such that, if...

Yes. Unless there is a protection diode or a mechanical safety, reverse polarity will damage any diode or diode-driven laser.

GITD is basically fluorescence with a really long decay time. If you were showing a moving image, a good GITD material would probably make the image too smeared and blurry, but maybe a really awful, cheap, GITD material would make the image look "artsy."

Does the dot in the demonstration video look yellow?! Interesting find. For the price, might be worth a risk if anyone's feeling brave.

Do you have any of the actual quotes to share? What does the 1/6 Commission have the authority to actually do?

Will the green ZnS:Cu fluoresce at diode laser wavelengths, though? I thought it'd only fluoresce at really short wavelengths. I guess the easiest way to tell would be to carefully shine the diode in question on a CRT and see if it glows white or some other colour. If the glow is pink...

And, when caught in this lie, have Schumer lie and say that all of the Americans are out. Also, no modern president ever got elected by telling the truth. In fact, each president lies more than their predecessor.

Actually, this is a great analogy, whatever your political leaning. According to The Addabbo Health Center in NYC, the #1 reason minority people in NYC have cited for not getting vaccinated is missing work, and the #2 reason is having to show ID (ID is not required, but proof of age is, which...

What I would call a beam dump, a black hole, so to speak, isn't a bad idea to have handy, especially with a >3W laser. You can make your own with a plumb bob and a metal tube.
