Alien Planet starts out with an interstellar spacecraft named Von Braun , leaving Earth's orbit . Traveling at 20 % the speed of light , it reaches Darwin IV in 42 years . Upon reaching orbit , it deploys the Darwin Reconnaissance Orbiter , Which looks for potential landing sites for the probes . The first probe , Balboa , explodes along with its lifting body transport during entry , because one of its wings failed to unfold . Two backup probes , Leonardo da Vinci and Isaac Newton , successfully land on the planet , and learn much about its bizarre indigenous lifeforms , including an apparently sapient species . The robotic probes sent out to research on Darwin IV are called Horus Probes . Each Horus probe consists of an { { convert } } long inflatable , hydrogen-filled balloon , Which is covered with solar receptors , a computer ' brain ' , a ' head ' covered with sensors , and several smaller robots that can be sent to places too dangerous for the probes themselves . The probes have a limited degree of artificial intelligence , very similar to the ' processing power ' of a 4-year-old . All the real thinking is done by a supercomputer in the orbiting Von Braun . The probes are programmed with different personalities ; Ike is more cautious , while Leo is the risk-taker . The two probes are also equipped with a holographic message that will be projected to any sentient life found on Darwin . After the two probes inflate their gas-bags , they encounter a voracious Arrowtongue and watch it pursue a Gyrosprinter .

The probes have differing personalities and the intelligence level of what?

Dr. Benjamin Stone is a hotshot young surgeon who longs to leave the drudgery of a Washington , D.C. emergency room and finally leaps at his chance at more money and less death as a plastic surgeon in Beverly Hills . On his last day , Ben's relationship with his co-workers is presumed to be anything but a warm one . None of his colleagues will join him for a drink and a cake in his honor has an iced portion of the phrase '' Good riddance , asshole '' sliced out . Ben's cross-country drive in a 1956 Porsche 356 Speedster is interrupted when he crashes in the rural hamlet of Grady , South Carolina . The crash damages the fence of local Judge Evans , who sentences him to community service at a nearby hospital . Ben offers to pay for the fence , but the stern judge increases his community service each time he talks back . Defeated , he reports to the hospital , where Nurse Packer humbles him by ordering him to clock in and out , as would a factory worker . Though upset , Ben quickly makes friends with Mayor Nick Nicholson , the town cafe's proprietor/head waitress , and Melvin , the local mechanic tasked with repairing Ben's car . Ben soon finds his clinic work to be much more laid-back than the emergency room . He has simple cases such as spots before the eyes , fishing hook impalings , and even reading mail for a young illiterate couple , whose baby he later delivers . The experience also humbles Ben when he mistreats a case of mitral valve regurgitation leading to late cyanosis in the child .

Name two pieces of information that show that Dr. Stone probably is wealthier than the average person.

Light rays strike a reflecting surface. They are then reflected back. You can predict the angle of the reflected light. Imagine a ball bouncing off a surface. Light can do the same thing. That is, assuming the surface is shiny. So how do you know where light will go after it strikes a shiny surface? It depends on how the light initially strikes the shiny object. Light does not always go straight toward a surface. Therefore, not all light bounces straight back. Sometimes, light can hit a surface at an angle. The angle at which it strikes the surface tells us how it will bounce off. While light is different to a ball, they react in a similar manner. Many sports rely on knowledge of reflection. Pool players know a lot about reflection. They take great care when they strike the pool ball. They need it to go to a certain place. They know the angle it will hit the side of the pool table.
