Experience this sphere powered by the sun! The vanes in the Radiometer are
alternately dark and light in color. When the light strikes these vanes, it
transfers heat to each one - but not at the same degree. The lighter vane
reflects the rays and the darker vane absorbs the rays. The... 阅读全帖

NASA satellite data from the years 2000 through 2011 show the Earth’s
atmosphere is allowing far more heat to be released into space than alarmist
computer models have predicted, reports a new study in the peer-reviewed
science journal Remote Sensing. The study indicates far less future global
warming will occur than United Nations computer models have predicted, and
supports prior studies indicating increases in atmospheric carbon dioxide
trap far less heat than alarmists... 阅读全帖

来自主题: JobHunting版 - 计算电磁学求软件公司内推
本人在法国读的博士,计算电磁学方向,简单地说就是计算电磁场分布的,研究各种算
法但是不懂硬件设计。12年毕业后鬼使神差做了2年薄厚,14年来到美国继续做薄厚,
大方向还是这些,加入了一些微波遥感的工作内容。不是大牛。不想再在学术界待了,
想要找个工业界的工作。
找了1个多月吧,发现做电磁的机会真的很少。本来方向就很窄,很多沾边的还都要公
民身份。一圈找下来,发现能做的基本就剩下一些做电磁计算软件的公司,例如Ansys
。投了几家,也没有回音,很是苦恼。有见到加州有一些小公司也做这类工作。我不介
意公司规模和待遇,只是希望找到第一份工作好攒工作经验。
我的电磁理论基础还是比较好的。编程能力也不错,有用C++写科学应用程序(用来控
制radiometer的,涉及多线程,Ethernet通讯,AD卡IO卡控制等。基本就是我一个人写
的)的经验。希望找一份computational electromagnetics engineer的工作。地点,
待遇不限,就是需要转身份。希望有资源的大大们分享一下信息。能内推一个就更是感
激不尽了。
有一个比较大的问题是我现在是J1身份,也没有美国本土的学位... 阅读全帖

来自主题: Physics版 - 据说老爱发表了300多篇论文
我还算有知的,无论深度还是广度,奈何世界上的知识太多。
有人贴出老爱的几百篇论文,我一看大多数是德文,不知道,无法判断。
您瞅一眼,看看有多少是真正的科研论文?

NASA Releases Stunning Animation of Earth at Night
SAN FRANCISCO—This incredibly detailed 360-degree view of Earth at night
was unveiled during a December 5 presentation at the American Geophysical
Union conference. NASA stitched together two months of imagery taken by the
new Visible Infrared Imaging Radiometer Suite (VIIRS) satellite to create a
completely cloud-free view of the nighttime planet.
The resolution of VIIRS is six tim... 阅读全帖
