Sigh. The point is not to have children right now, or not, etc...or if your ex-wife will bad mouth you (sorry?). The POINT is that you should live your life as if your child will know what you did/didn't do. Think about what you do in terms of how you'd FEEL, explaining it to your child...

The issue with Chinese knock offs OF Chinese knock offs has gotten a bit (more) out of hand. The best way is to get a few more than you need (Assuming they were cheap ENOUGH to justify it...), and cut some open when you get them. Its about the only way to tell what you have. Obviously, when...

Congratulations! Its not a bad career choice at all...some buddies who went that route were happy they did. Just decide to live the rest of your life with the assumption that ANY part of it may one day be explained to your child. You get to decide what that child might hear. :beer:

Plan C - If you want more performance, but with a two celled solution for voltage, but have it fit where an 18650 fits, use two 18350 instead of one 18650. You can get a lot more amp supply for high drain applications, you get the doubled voltage, and your useful MAH will be the same as for...

I've had good results with the Nichia NCSU033B LED - it puts out about 450 mW at the 365 nm peak, in my application. For a single 18650 sized light, I find the visible part of the beam is minimal, but the florescence is excellent. For my uses, a "perfect" 365 nm UV light will look like a...

Its not REALLY that light for example "knows" if its being watched or not....it would not care either way. The twin slit experiment uses the presence of an interference pattern to determine if its found waves, and twin lines to determine the presence of a particle. After that, its about...

Did you mean this one? :D And correct, things make sounds regardless of audience. The sound needs to be heard to be called noise though.

No, I'm saying that sound is the propagated wave, and that noise is what we call our perception of that wave. So, if something sends a vibration through the air (The propagated wave)....that sound is there even if no one detects it. If it is detected, sound can be called noise....therefore, if...

Was the spot you saw from the dot ON the glasses, or, were you looking at a dot on something a ways away from you? Cataracts would be the primary concern for that wavelength...which may take a while to develop if you really got a direct hit. The glasses at least tend to spread the dot out a...

If the tree falls in the woods, and there's no one to hear it, it DOES make a sound....it just doesn't make a noise. :D Sound is the wave propagated, noise is the perceived sound.... So it makes a sound, but, no noise.

Found this: In 2014, some guys at MIT found that they could recreate and explain the interference pattern of the double-slit experiment with a classical system, using an experiment involving bouncing droplets of oil. The experiments involve an oil droplet that bounces along the surface of a...

Its a popular flashlight host. You can get them on DX, etc.

Re: NASA Warp Drive Project - "Speeds" that Could Take a Spacecraft to Alpha Centauri I didn't see the movie, but the book was good.

A major factor to consider is the REACTION of the people vs reaction by a government. If "Muslims" attack Christians for example, lets say for example, some Saudi Backed Terrorists knock down the Twin Towers in NYC, we - as a country, fly into action, and bomb Afghanistan still further into the...

That's 1,000 nW....or one microwatt (uW), which is not even a Milliwatt (mW).... Which is to say ridiculously weak and/or ridiculously mislabeled. :eg:

OD 4 is not a HIGH level of protection though....its marginal. IE: If worried, frankly, I'd get at least OD 5 - 7 range specs for the wavelengths you use.

I also like hosts that can use both 18650 and 18350 cells to give voltage flexibility. I actually use mine as pointers, so, the smaller the form factor the better for me at least...balanced against the need for heat sinking as I do use longer run times. If a side clicky, I need it to have a...

Ironically, I sent an overnight package to Florida, and it ended up stopping and doing some sight seeing in Memphis Tennessee instead. I called Fedex and apparently the plane had mechanical problems and was routed to Memphis which is a main hub. The case the samples I sent the package to the...

I just read the links, and, its a VERY narrow interpretation of the circumstances. IE: The exceptions are significant, but glossed over with anecdotal references to ways around it (federal sharing, etc). The reality is that the odds of a policeman walking over and demanding your shoes, or...
