Dave Williams was born in Saskatoon, Saskatchewan. Hadfield and Parazynski connected cables that will feed the initial electrical power, computer commands and video between the station and the new robot arm, which is also known as Canadarm2. They installed and deployed an ultra high frequency communications antenna that will enable the station to conduct future space walk communications and that will improve future shuttle-station communications. Then, they released launch bolts that held the Canadarm2 secure during its trip to orbit, unfolded the arm and prepared it for control from inside the station. Max Planck 's birthday, pioneer quantum physicist.
Blackbodies are perfect absorbers of light and approximate stars over a wide range of conditions.
Planck's earliest work was on the subject of thermodynamics. He published papers on entropy, on thermoelectricity and on the theory of dilute solutions. In a paper published in 1900, he announced that the energy emitted by a resonator could only take on discrete values or quanta. The energy for a resonator of frequency v is hv where h is a universal constant, now called Planck's constant. He was revered by his colleagues, particularly by Albert Einstein, not only for the importance of his discoveries but for his great personal qualities.
