there is astronomy, the study of celestial objects and the physical universe. On the other hand, we have astrophysics, a branch of astronomy that employs principles of physics and chemistry to elucidate the birth, life, and death of stars, planets, galaxies, nebulae,...
Forum: Astronomy and Astrophysics P Can’t tell the difference between a “good” school and a top 5 private school I’m not sure what I was expecting to be honest. Definitely not an entire campus population of geniuses but I’ve spent the past 2 months here (albeit as a research ...
on the basis of function or using a combination of both. Most schemes begin by distinguishing between the central nervous system or CNS, which includes the brain and spinal cord, and the peripheral nervous system, which includes all other nervous-system tissue. The PNS in turn is divided into...
Unlike females, male lions leave their birth prides at between two to four years of age. They initially form groups or coalitions with other young males from their pride. During this period, the males roam and progress toward full maturity. Upon reaching maturity, they seek to establish their ...
a well-defined upper limit exists. Most shell stars are located in the upper limit region. The shell stars all havevsini/vcrilarger than the normal Be stars in the upper limit region. This strongly suggests that the distinction between shell stars and normal Be stars of high equivalent width...
The Main Differences Between Mass and Weight How Much Do You Weigh on Other Planets? While a person's mass doesn't change elsewhere in the solar system, theaccelerationdue to gravity and weight varies dramatically. The calculation of gravity on other bodies, as on Earth, depends not just on...
One interesting aim of the IYA is to encourage more diversity (多样性) in the field of astronomy and physics. IYA organizers hope that the yearlong celebration of astronomy will inspire more females and underrepresented minorities to pursue (追求) careers in science. An event that will help furt...

An atom can be an ion, but not all ions are atoms. These are the important differences between an atom and an ion.
When comparing unisex flowers, the males will usually have many stamens rich with pollen while the females only have pistils. The appearances of pistils and stamens vary between species, however, pollen is often brown or orange, making the anther and filament distinct, while the pistil is usu...
