http://en.wikipedia.org/wiki/Red_poppy
Due to the extent of ground disturbance in warfare during World War I, corn
poppies bloomed in between the trench lines and no man's lands on the
Western front. They were immortalized in the poem In Flanders Fields by
Canadian poet and soldier Lt Col John McCrae. Similarly, it is a symbol of
the blood of Polish soldiers killed in the Battle of Monte Cassino in the
Polish war song Czerwone maki na Monte Cassino (Red Poppies on Monte Cassino
).

Your baby will also like to work on her fine motor skills by fiddling with

Plastic shuttles feel heavier than feather. Plastics fly too fast for a
smash, because the skirt deforms and isn't as effective as feather to create
air drag to slow it down. The flight is also different from feather for

Shotgun Home Defense Ammunition
(Tactical Briefs #10, October 1998)
For home defense, a shotgun is superior to a handgun in terms of being able
to stop a violent intruder as quickly as possible. A reliable, well-made,
pump-action shotgun can usually be purchased for less than the cost of a
handgun of comparable quality. Also, inexpensive birdshot ammunition,
typically used for trainin... 阅读全帖

来自主题: GunsAndGears版 - 新Tikka T3 Lite, 30-06,$340, 值得买么?
如果你把Chuck Hawks当作gun god,你应该看看Chuck Hawks怎么贬Tikka T3的,这里

A Critical Look at the Tikka T3
(And Other Economy Hunting Rifles)
By Chuck Hawks
Like many old geezers, I bemoan the loss, or lack, of standards in our
modern world. And nowhere is this devaluation of quality more evident than
in 21st Century hunting rifles. (Actually, the slide started in the 1960's
and accelerated toward the end of the 20th Century).

据magpul的测试,他们的弹匣可以一直压着弹簧也不会有问题。其实这牵涉到材料科学
上面的三个概念,因为这是我的专业,所以我来给大家说说。这第一个概念叫做
elastic vs. plastic;第二个概念叫做creep;第三个概念叫做ductile to brittle
transition。
先说第一个概念 elastic vs. plastic。弹簧在其设计的弹性范围之内的伸缩都应属于
elastic区域,也就是说是不会有永久的形变导致弹簧失效的。而如果你在三十发的弹
匣里压了三十一发或者故意把弹簧拉长一节,那就会导致plastic deformation,也就
是弹簧的长度会有永久性的变化,这时候弹簧可能就会有不给力的情况了。
第二个概念creep是指的弹簧在长期受力情况下tensile stress和yield stress都会慢
慢变小,也就是说plastic deformation会提早发生。可是注意一点,假如是在室温情
况下,这个过程是会很长的,尤其是在弹簧的材料有很大进步的今天,要等到creep的
发生估计你一辈子都等不到。但是如果温度变高很多,不如说从室温变到几百度... 阅读全帖

看来不满的P+用户还不少啊,而且竟然在P的大本营里发飙。。。
So a full plastic 35/2.4 is available at Nikkor 35/1.8 price?
"
weight is 124g, says plastic barrel, looks like plastic mount in news photo.
Nikkor 35/1.8G is 200g with metal mount, and SWM motor, SWM MOTOR!!!
And, BTW, maybe u don't care, it's 1-stop faster.
This is really depressing news for me. I could accept DA35/2.4 at $60, what
ever the IQ is. A F/2.4 is a F/2.4.
If pentax releases DA35/1.8, it will kill FA31, yes, it's right. But a lens
like DA35/2.4 at impr... 阅读全帖

来自主题: PhotoGear版 - 有点不明白:单反的机身材料
Let me give you the professional answer on this question:
I am in the business of plastic. I sold Polycarbonate for 20 years.
Magnesium is lighter because they can put thinner wallbut polycarbonate will
absorb shock better. No polycarbonate would have no crack. Plastic is more
versatile as you can put more function in the molding than magnesium. One of
the best advantage of magnesium is an electronic shielding.
Volume is also an important criteria. Polycarbonate molding , when part come

Those not confident about their soul seek to hide their shallowness under a
better appearance. but they never know that the beauty of women, or the look
of a man, never presents with just geometrical perfectness of parts of
their body or their ratios, but instead sparkles from confident and focused
eyes, gushes through the elegance of gestures and movements , and most
important, transmit with kindness and consideration to others.
