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.
Scientists have drilled ice cores deep into glaciers and found ice that is 123,000 years old in Greenland2 and 740,000 years old in Antarctica.3 These annual layers go back much farther than the 10,000 years advocated by the young earth creationists. The Earth must be at least 740,000 years old.
