Francesco Redi, the founder of the experimental biology, is recognized to be one of the greatest biologists of all time. A biologist, or biological scientist, is a scientist who studies living organisms, often in the context of their environment. Biologists involved in fundamental research attempt to explore and further explain the underlying mechanisms that govern the functioning of organisms. Biologists involved in applied research attempt to develop or improve more specific processes and understanding, in fields such as medicine, industry and agriculture.
Satellites move in a path around the Earth called an orbit. Every satellite must have an orbital path (remember, satellites that travel into deep space to look at distant planets are not true satellites, they are in fact space probes), and the type of path it takes is determined by the physics involved. satellite's orbit works because of a balance between two forces. The orbit is a combination of the satellite's velocity-the speed it is travelling in a straight line-and the force of the Earth's gravitational pull on the satellite.
Orbits 'R' Us! When we talk about how Earth and the other planets travel around the Sun, we say they orbit the Sun. Likewise, the moon orbits Earth. Many artificial satellites also orbit Earth. When it comes to satellites, space engineers have different types of orbits to choose from.Satellites can orbit Earth's equator or go over Earth's North and South Poles. . . or anything in between.They orbit at a low altitude of just a few hundred miles above Earth's surface or thousands of miles out in space. The choice of orbit all depends on the satellite's job.atellites can orbit Earth's equator or go over Earth's North and South Poles. . . or anything in between.
