what to know about DSSS vs OFDM. In all the detail on DSSS and OFDM, I have missed which characterics of DSSS and OFDM make these distinct technologies. Nothing I've read appears to contrast the two. As I understand it, both DSSS and OFDM are intended to send many bits in parallel.
SCIENTIFIC AGE OF THE EARTH. efore analyzing the arguments advanced by creation âscientistsâ for a very young Earth, I here summarize briefly the evidence that has convinced scientists that the Earth is 4.5 to 4.6 billion years old.
Earth was once a âwaterworldâ much like the one depicted by Hollywood, scientists believe. A new model of the early Earth suggests that until around 2.5 billion years ago oceans covered almost the whole of the planet. Just 2% to 3% of the Earthâs surface would have been dry land, compared with 28% today. Earth was once a âwaterworldâ, scientists believe. The Earth at that time may have resembled the way it looked in Waterworld, the 1995 post-apocalyptic sci-fi movie starring Kevin Costner. In the film, humanity struggles to survive after the ice caps melt and inundate the planet with water.
