Crossing the Rubicon

4.0 out of 5 stars regarding heat-fading issue: you can get it back, September 17, 2010 By indystdnt - See all my reviews This review is from: Pilot FriXion Ball Fine Point, Black Erasable Gel Ink Pens, Dozen Box (FX7-BLK) (Office Product) After reading the comments regarding the ink disappearing when exposed to heat, I conducted an experiment. To summarize, if you lose something due to heat exposure, there is a very good chance you can get it back. My not-so-scientific scientific experiment: For my experiment I used Frixon Point 04 in purple, blue, pink, and green (darkest color to lightest). On the left side of the paper, I used a hair dryer to make the ink disappear (happened within seconds). On the left side of the paper, I erased using the frixion nub. I then placed the sheet of paper in the freezer. heat exposed side: Purple came back the best, followed by blue and pink (tie), and green did terrible. Purple looked almost pre-heat-exposure quality while blue and pink were easily readable. Green was visible, but very hard to make out. Conclusion: freezer method works great for dark colors for accidental heat exposure. Light colors did terrible. nub frixion side: Not so good. If you use the nub and (for some reason) want it back, you will get something from the darker colors, but it will be light. I can just barely make out the light colors, but perhaps a longer freezer exposure will help. CONCLUSION: if you lose something via accidental heat exposure or frixion nub error, you can likely retrieve it via placing in freezer for a few minutes (though you’ll have to squint harder on the lighter colors). I would also note that once the paper returned to room-temperature after removal from the freezer, the colors DID NOT fade. I love the pens. I agree with other reviews, that the ink runs out fast and the nub should be at the end of the pen cap. I get annoyed having to remove the cap every time I want to erase. You shouldn’t use the pens for legal documents (since they are erasable and you would never complete a legal document in pencil) or documents you submit to someone else (you don’t know that THEY won’t accidentally subject the document to heat, thereby rendering the page blank, and they won’t know to stick the darn thing in the freezer).

Never regret. If it’s good, it’s wonderful. If it’s bad, it’s experience.

Description Documentation The C8800-series is a 1000x1000 pixels high resolution digital camera using a high-speed frame transfer CCD chip with no mechanical shutter. The extraordinary spectral response characteristic allows application from the UV-range up to the NIR-range. The 12 bit digital output with a frame rate of 30Hz and a high signal to noise ratio is suitable even for low light level imaging. The C8800 also supports sub-array and binning modes which enables higher frame rates of more than 100 frames per second or higher. For long integration a cooling function with a permanently sealed vacuum chamber is available (Model C8800-21C). brochure Compatible

居然这么贵！！！！！

希尔伯特有一个学生,给了他一篇论文来证明黎曼猜想,尽管其中有个无法挽回的错误,希尔伯特还是被深深的吸引了。第二年,这个学生死了,希尔伯特在葬礼上做个演说。那天,风雨瑟瑟,这个学生的家属们哀不胜 收。希尔伯特开始致词,首先指出,这样的天才这么早离开我们实在 是痛惜呀,众人同感,哭得越来越凶。接下来,希尔伯特说,尽管这个人的证明有错,但是如果按照这条路走,应该有可能证明黎曼猜想,再接下来,希尔伯特继续热烈的冒雨讲道:“事实上,让我们考 虑一个单变量的复函数……

I have found the paradox, that if you love until it hurts, there can be no more hurt, only more love.
