Challenges In Measurement

There are many challenges that were presented to his history of scientists but they were able to overcome them with ingenuity and inventions. The topics that I will be discussing it how early scientist came up with formulas to determine the mass of the sun, what is the distance to the moon, and the speed of the earth's orbit. How they determine this having to use indirect forms of measurement to overcome these challenges

We will also discuss history and influence of the telescope and microscope and how it had a great influence on science in the past and currently today.

Finally the hazards associated with physical science and the safety precautions necessary to work and these types of environments. The personal protection equipment required working with chemicals and this hazardous equipment would be discussed.

Challenges to making indirect measurements on the distance to the moon. “The ancient Greeks did it, and you can too. Find out how some easily observable facts allow you to measure the approximate distance from the Earth to the Moon. One of the hardest parts of calculating distances in space is the difficulty finding reference points. The size or distance of objects on Earth can be hard to estimate, but they occupy a landscape, which can be measured, providing a jumping-off point. The moon gives up a few clues — it's clearly closer than the Sun or the stars, but it's still drifting in a nothingness that's hard to measure. The Greeks already figured out the circumference and consequently the diameter of the earth, providing the one absolute number on which to base the rest.” Read more: http://www.universetoday.com/103206/what-is-the-distance-to-the-moon/#ixzz2htiDNaTl

Challenges to making direct measurements on the distance to the moon. “Astronomers calculate the distance to the Moon using the Lunar Laser Ranging experiment. When astronauts visited the Moon more than forty years ago, they left retro reflecting mirrors on the...
