In Taylor & Wheeler’s Spacetime Physics, they basically show one very good example of the invariance, then they instruct the reader to take it as gospel (In case you don’t have their book completely memorized, go here and read pg 22-25).
They then use the interval’s invariance to develop the Lorentz transformation.
After the Piltdown fraud was exposed, the australopithecines came into favour as a transitional form linking an ape-like common-ancestor to human beings, and this link was further strengthened by later finds of both erectus and australopithecine fossils, mainly in East and South. By the early 1970s, more finds including australopithecus-like material classified as one of the most urgent tasks involved was how to respond to this apparent chain of evolutionary progression.
In the intervening years since then, creation-oriented scientists have made a number of attacks on the validity of most of these forms, some of them being of high technical quality, others a little less well-informed.
Reionization marks the point at which the hydrogen in the Universe became ionized.
When there is yet another claim that a missing link has been found, the question arises, where is the chain in the first place?Physicist: It’s worth noting real quick that this post is aimed at people who have recently taken intro relativity.That said, if you’re hip with pre-calc, then you’re ready for the basics of special relativity (like this post).With the discovery of Java and Peking ), in 1891–18–1937 respectively, evolutionary theory received a considerable and much-needed boost.Until Dubois’ Java discoveries, the only alleged link between man and the apes had been a few Neanderthal specimens.
