(CNN) -- Police in Northern California have arrested an elementary
schoolteacher after she allegedly brought marijuana-laced food to an after-
hours employee potluck dinner.
Teresa Gilmete Badger, a 47-year-old teacher at Matthew Turner Elementary
School in Benicia, was arrested Friday afternoon on suspicion of poisoning
after a six-week-long investigation, said Lt. Frank Hartig of the Benicia
Police Department.

What happened to those $ millions from the Bernie Sanders campaign?
By Thomas Lifson
For those who want to get rich off of politics, the surest racket is to
become the media buyer for a major campaign. For the underwhelming task of
actually buying television airtime and print space, one receives a huge
commission of 15%. If a campaign spends ten million bucks on television
advertising, the buyer gets a million and a half.
For the Bernie Sanders campaign, which raised over $90 mil... 阅读全帖 |

說明: 離我們二十億光年遠的星系團Abell 1689，是宇宙中最大質量的天體之一。
在上面這幅由哈伯望遠鏡先進巡天相機所拍攝的影像裡，Abell 1689正如同愛因斯坦
重力理論所預測的，扭曲了它後面星系所發出的光，產生了多個變形的影像。 天體
巨大重力透鏡效應的強度和它的質量有關，不過影像中這群泛黃星系的可見物質，只
佔造成這些背景星系弧狀影像所需要質量的百分之一而已！ 事實上，造成這種宇宙
空間扭曲，並產生這種重力透鏡效應的大部份質量，是一種仍然很神祕的暗物質。
我們會知道星團的主要重力來源 |

Explanation: Two billion light-years away, galaxy cluster Abell 1689 is one of the most
massive objects in the Universe. In this view from the Hubble Space Telescope's Advanced
Camera for Surveys, Abell 1689 is seen to warp space as predicted by Einstein's theory of

发帖数: 650 | 7 The Summit of Aconcagua (6956m)
Hermann Hartig, March 93
(H*************[email protected])
Overview
Aconcagua, 6956 meters high, is the highest mountain of the Americas
and the highest mountain outside of Asia. The "normal route" leads to
the summit of Aconcagua without the need for technical climbing.
However, due to possibly very low temperatures (below -30 C),heavy
(snow) storms and especially due to high altitude, it can be very
dangerous! Good equipment, physical fitness and a very carefu |
