I give my respect to Myfanwy94 (http://www.youtube.com/watch?v=-g3EpSTiAO8) who was a member of this forum that was brave enough to attempt hydrazine synthesis! He died at age 15! RESPECT!


I'm at a loss for words. The best reply I can come up with: <em>wot?</em> I'm honestly unsure if you're serious or trolling.

<strong>hyfalcon</strong>, she has an element named in her honor (<a href="https://en.wikipedia.org/wiki/Curium" target="_blank">curium</a> <img src="../scipics/_wiki.png" />;)!

[edit]
I wouldn't call <a href="http://en.wikipedia.org/wiki/Gordon_Moore" target="_blank">Gordon Moore</a> <img src="../scipics/_wiki.png" /> a scientist, more of a tycoon. I respect <a href="http://en.wikipedia.org/wiki/Michio_Kaku" target="_blank">Michio Kaku</a> <img src="../scipics/_wiki.png" />, but I wouldn't list him as one of "the greatest scientists in history"&mdash;especially considering that he's still living. <a href="http://en.wikipedia.org/wiki/David_Hahn" target="_blank">David Hahn</a> <img src="../scipics/_wiki.png" />, the "Radioactive Boy Scout", enough said. <a href="http://en.wikipedia.org/wiki/Wernher_von_Braun" target="_blank">Wernher von Braun</a> <img src="../scipics/_wiki.png" />, okay, maybe I can see that. But you couldn't even spell his name correctly. <a href="http://en.wikipedia.org/wiki/Thomas_Edison" target="_blank">Thomas Edison</a> <img src="../scipics/_wiki.png" /> was a liar, a thief, and a murderer (recklessly endangering the lives of his lab assistants, at least one of whom died as a direct result)&mdash;a true American capitalist. He was also more of an inventor/engineer than a scientist. As for <a href="http://en.wikipedia.org/wiki/David_Packard" target="_blank">David Packard</a> <img src="../scipics/_wiki.png" />, like Gordon Moore, I don't see how he fits into the category of "greatest scientists".

I don't think I would want to have an element named after me if I had contaminated myself the way she had.

Her <a href="http://www.csmonitor.com/Innovation/Horizons/2011/1107/Marie-Curie-Why-her-papers-are-still-radioactive" target="_blank">notebooks</a> are still highly radioactive, and must be kept in a lead-lined vault. She won the 1903 Nobel Prize in Physics <em>and</em> the 1911 Nobel Prize in Chemistry&mdash;the only person to win a Nobel Prize in two sciences. I just <a href="viewthread.php?tid=18706#pid290634">posted</a>, in another thread, a good book about her discovery of radium.

I'll tell you why you're NOT sacrificing yourself "to science" in your situation. You're not accomplishing anything new, you're just messing around with toxic compounds that are well researched. This "inspirational" paragraph you wrote is ridiculous, because you're not research anything, you're just hurting yourself or putting yourself at risk to do so! Essentially... you're fighting without a cause for something that leads to nothing. If you want to research chemistry, pharmacology, etc., do it to research, not to appear like some massive stoic hero, do it like a scientist. This means proper precautions, extreme preparation & competence *prior to experimentation* (because you're not going to accomplish much if you're just... doing it... you should justify but learn at the same time), all of that. I honestly can't imagine why you would willing to unnecessarily risk your physiological health except for delusional vile, vain reasons. It isn't "cool" to do that, it just makes you look ignorant.

Back to the actual topic of the post, this is a general question, but does a microwave oven supply too much or too little radiation for mutation?

Microwaves are far too low-energy to cause mutation. You'd have a better chance of causing a mutation with sunlight.




Please remember: "Filtrate" is not a verb.
Write up your lab reports the way your instructor wants them, not the way your ex-instructor wants them.

This. Microwaves are non-ionizing, and merely energize water's rotational excitatory states, causing kinetic energy to release in the form of heat.
Seriously, if anyone wants to mutate bacteria, seeds, fungi, etc. just use a UV lamp. That's what I've done in labs that didn't want to bother with radioactive materials licensing, and it works.

Would Black Lamp Style be powerful enough?

Good question. I'm not sure. I used a standard laminar flow hood's UV light for varying exposure intervals after consulting with an equipment person about the bulb. Based on some papers I had and their order specs, we decided it was good enough and it worked.

"Black lights" output UV-A radiation, i.e., between about 330 nm and 400 nm wavelength. Mutations are caused by DNA damage. This requires UV-B or higher energy - wavelengths shorter than about 280 nm. So a black light would be nearly useless. You want a germicidal lamp or a short-wavelength UV source. Be sure to arrange things so you can't look at the lit lamp - can also cause eye damage.
