Laserscopes

Almost all lasers emit more light at a specific frequency than a similarly sized portion of the sun's surface..

While laserscopes can be a good value for the power, unless you are doing certified large-scale shows, you are a surgeon, or you are a laser technician refurbishing it to be sold to a surgeon or show company there is no purpose in having one. It's very unwise to use them in a closed area (such as inside a house) unless you have a very good beam stop and access to the area is tightly controlled. You can't use them outdoors without being certified and/or without clearance from whatever aviation authority governs where you live. They're beyond dangerous and will set most things on fire immediately. It's just not worth it for 99.999999999% of the people on this planet to have one.

Alright then. Well, i'd still like an argon, maybe 200-500mw, but i'm broke. I need to find someone who'd like to buy all my x-ray machine parts, (i quit the project)

Ebay, (or similar), is probably the best way to convert your X-ray capital to cash, and LPF is probably your best bet to convert your capital to Argon! (Ebay can also help you with your conversion from capital to Argon but you gamble all the way... !!!!!!!)

BTW what does this mean in your sig? - U238 α→Th234 β→Pa234 β→U234 α→Th230 α→Ra226 α→Rn222 α→ α→Pb214 β→Bi214 β→Po214 α→Pb210 β→Bi210 β→Po210 α→Pb206 -

I recognise the uranium isotope U238 used in an atomic bomb such as Hiroshima but is the rest a summary of the fusion, non-fusion reactions of said atomic explosion?

Looks to me like the radioactive decay of a Uranium238 atom

^Makes sense. The atomic numbers decrease in fours. Hardly the obliteration of nuclear fission, (not fusion)! Then again I'm no Nuclear physicist. More like an Unclear Physicist! Ha!

Is that a, "Half life", from one element to the next? A google search will no doubt determine this, and how long it is, but who's got time for that? I need to sleep man! :tired:

Still interesting though... Maybe a, 'tomorrow', project as I now need to wait for parts to complete what I was doing, due to stupidity... :scowl:

A half life is the time it takes for one half of a radioactive element (usually a isotope) to decay. The arrows are not half lifes, but the element (isotope) that is prduced by radioactive decomposition. The little letters are either alpha or beta radiation that is emitted. A half life is pretty much just a measure of how fast a certain element decays.

All of the isotopes are linked to wikipedia in his signature, the path a radioactive element takes is pretty interesting!

It's quite interesting to note that something as simple as a lead fishing weight might could be referred to as "High-performance Depleted Uranium!"

Also interesting how it cycles through a few elements at different weights.

I'm fairly certain most lead did not originate from uranium. That much decay probably takes longer than the universe has been around.
