The Age of the Earth: Radiometric Methods
Radiometric dating measures how the proportions of different elements in
rocks differ from their initial ratios. For example, Uranium-235 decays into
Lead-207 at a fixed, measurable rate. As time passes, there will be more
lead and less uranium, so we can use the relative amounts of lead and
uranium—their ratio—to determine the age of the rock. Using the uranium/
lead system, the age of the earth has been determined to be 4.566 billion
years, with a marg... 阅读全帖

Sir — The question of religious belief among US scientists has been debated
since early in the century. Our latest survey finds that, among the top
natural scientists, disbelief is greater than ever — almost total.
Research on this topic began with the eminent US psychologist James H. Leuba
and his landmark survey of 1914. He found that 58% of 1,000 randomly
selected US scientists expressed disbelief or doubt in the existence of God,
and that this figure rose to near 70% among the 400 "greater" ... 阅读全帖

What is real?
Take for example the first successful theory of gravity, Ptolemy's system of
epicycles. It was used before Newton to describe the motion of the planets,
by assuming that the earth was static in the center of the world and the
planets and the sun revolved around it. It gave relatively accurate results
for astronomical observations. Was it real? I guess not. It just helped the
calculations, correctly, to be carried out.

做science的人叫scientist,-ist结尾的。其他以ist结尾的词还有
artist, physicist, biologist,听上去都还不错,可是还有racist,rapist

To date, he and his team of more than a dozen volunteers have discovered 54
supernovae. Fifty of those finds were made in just 46 months. The hunters

noted during a "space roundtable" held July 10th in Washington, D.C.,
governments should be doing more to find these and other near-Earth objects
(NEOs). Titled "The Asteroid Threat: Identification and Mitigation
Strategies," the roundtable was organized by ProS

2002年2月5日—业余天文爱好者们一直梦想控制他们自己的空间轨道天文望远镜,
而这一宏伟的梦想终于在上周初见倪端。2月2日Astronomical Leag
