of you believe in aliens? Well if you don’t‚ here are a bunch of reasons why you should believe that aliens exist. Let’s consider galaxies first. There may be 100‚000‚000 galaxies‚ because an estimated 50 billion galaxies are visible with modern telescopes. Every galaxy must have a number of stars in it‚ as many as hundreds of billions. Now we all know that stars have planetary systems. Then it is also a well known fact that the dimming and brightening of a star is when a planet crosses its disk.

analysis; earning the status as the founder of modern mechanics and experimental physics (2). He also introduced the use of pendulums instead of clocks and proposed the law of uniform acceleration between falling objects. Finally‚ he developed the telescope with which he discovered the craters of the moon‚ sunspots‚ phases of Venus‚ and the satellites of Jupiter.

evaporation of flowing water. Looking through his telescope Lowell became convinced he could see a network of artificial canals. This led him to believe that there were intelligent beings on Mars who had built these canals. However‚ spacecraft have now visited Mars and found that there is no evidence of water at all. It is now thought that the lines he could see were the combination of Lowell’s overactive imagination‚ and scratches on the lens of his telescope. We are now searching one of Jupiter’s moons

in Juneau. I was so excited that I almost dropped my telescope into the deep‚ blue water. I could see a whale flipping in the water. It splashed the waves with its huge‚ flat tail and dived into the water. The captain drove the boat closer to the whales. One of them jumped out in a curved position. As it dived into the water‚ its tails waved back and forth. Water was splashed out on the top of a blue whale’s head. Looking there from the telescope‚ it looked like a fountain. This trip was extra-entertaining

a)What is the angular speed in radians per second? b) what is the linear speed in ft/sec? 30. The 25‚000 pound Hubble space telescope was launched April 1990 and placed in a 380 mile circular orbit above the earth’s surface. It completes one orbit every 97 minutes‚ going from a dawn‐to‐dusk cycle nearly 15 times a day. If the radius of the earth is 3964 miles‚ what is the linear velocity of the space telescope in miles per hour? 30) rθ/t ((4344mi)(2π)/97min)(60min/1hr) 168882.98 mph 31. Solve for θ in both radians and degrees

The Kuiper Belt The Kuiper Belt is a thick ecliptic band which contains over 200 million small‚ icy objects. These objects‚ known as the Kuiper Belt Objects or trans- Neptunians‚ were discovered in 1992 by Jewitt and Lu. The first Kuiper Belt Object discovered in 1992‚ is QB1 (1992) and is 150 miles wide. The Kuiper Belt is about 30 AU to 50 AU away from the Sun. The Kuiper Belt is very important because of two specific things; the first being‚ Kuiper Belt Objects are remnants from the earliest

AP 224 QSM 415 Land Surveying Chain Surveying What is chain surveying? Chain surveying is a type of survey in which the surveyor takes measurements in the field and then completes plot calculations and other processes in the office. Here only linear measurements are made i.e. no angular measurements are made. This is most suitable adapted to small plane areas with very few details. If carefully done‚ it gives quite accurate results. The necessary requirements for field work are Chain Tape Ranging

Johannes Kepler: Life‚ Laws‚ & Impact on Science Johannes Kepler was born the 27th of December 1571 and passed away the 15th of November 1630. He was born in Weil der Stadt in Swabia‚ a small town in Germany‚ and later moved with his family to Leonberg‚ which was a town nearby his birth town. Growing up‚ Kepler was said to be a very sickly child. He had gotten smallpox as a child‚ which crippled him with poor vision‚ and crippled hands for the rest of his life. He was a son to Heinrich Kepler‚ a
