Procedures in the Physical Sciences

Scientific Method: The scientific method is a method or procedure that uses precise measurements, predictions, and data to answer questions.

Identify three (3) specific challenges to making direct measurements in the fields of astronomy, chemistry, physics, or earth science. Describe how scientists have utilized indirect forms of measure to overcome these challenges

We can determine an object’s temperature from its thermal (or “blackbody”) spectrum by finding the wavelength at which it emits the most electromagnetic radiation.

Science should not be seen as a collection of facts, concepts, and useful ideas about nature, or even the organized analysis of nature, although both are common definitions of science. Science is a means of examining nature. In other words, science is a method of discovering reliable knowledge about nature. There are other ways of learning knowledge about nature; nevertheless science is the only way that results in getting hold of of reliable knowledge. Dependable knowledge is material that has high viewpoint of accuracy because its certainty has been defendable by a reliable technique. Reliable data is called standard correct idea, to distinguish reliable facts from belief that is false and unjustified. Every person has beliefs, nonetheless not all facts is steadily true and acceptable. Science is a method

The difficulty comes in the very word measurement which implies some form of numerical logic. If we look at known distance measurements one

Batteries store energy in chemical form. They release energy by pumping electrons’ through wires from the minus pole to the plus pole. Devices inbetween convert this energy to another form, Efficieny- e.motor=85%, combustion= 20%

19. What is the scientific method, and how does it relate to the science of astronomy?

Some limitations are that parallax angles of less than 0.001 arcsec are very difficult to measure from Earth because of the effects on the Earth’s atmosphere. This limits Earth based telescopes to measuring the distances to stars about 10.01 or 100 parsecs away. Spaced based telescopes can get accuracy to 0.001, which has increased the number of stars whose distance could be measured with this method. However, most stars even in our own galaxy are much further away than 1000 parsecs, since the Milky Way is about 30,000 parsecs across.

On a two-hour bus ride to a small, rural town in New Zealand with my school, we passed by numerous beautiful rolling hills and forests. While my classmates chatted, listened to music, and watched the landscape, I kept my eyes focused downward on my AP Physics binder. It was the summer before senior year, and instead of fully enjoying the month-long community service trip to a foreign country, I also focused on self-studying AP Physics 1 and 2. Because my school requires a prerequisite physics class before enrolling in AP Physics C, I had to learn an entire year’s worth of material over the summer. At the end of my Junior year when I was contemplating taking the harder physics class, one of the physics teachers told me, “No one has jumped straight into Physics C in many years, but I think you can do it.”

Below are the “Big Ideas” from throughout the year, as well as the two prompts that I would like you to address about each. Respond to the prompts (labeled “a” and “b”) by typing your answers below them. Please do NOT use bold or italicized font for your answers.

Do you want to know more about the universe, but dont have the time to actually pursue a detailed study? Then Astrophysics for People in a Hurry is exactly the book for you. The book describes the origins of the universe, delves deep into how it functions, and discusses different concepts of physics. Tyson tries to explain these concepts in the most simplified manner with a lot of humor. He also leaves us with not just a better sense of understanding of the universe, but also many questions about how to relate with the infinite cosmos with our own human and limited understanding.

Knowledge can be produced using a variety of different methods. However, in the natural sciences sense perception through observation is used primarily. This can be seen through the work of researchers who often observe the results of experiments and trends in order to analyze different phenomena and perspectives. While there are many scientific methods based on scientific thinking using logic and predictability, the idea that

“The Hubble, has given us nothing less than an ontological awakening, a forceful reckoning with what is the telescope compels the mind to contemplate space and time on a scale just shy of the infinite.” implied Ross Anderson, an engineer. With this one telescope, created by a normal astronomer, scientists and astronomers are able to see space as never seen before. They are able to make mind boggling observations that contemplate space to an infinite scale. Thousands of discoveries about space have been observed through this lense and without the magnitude of high level instruments compiled into this large instrument most of these observations would never have been discovered. As proposed by Floyd E. Bloom a researcher, on izquotes.com, “As

Since the beginning of recorded civilization, stars played a huge role in religion and proved vital to routing. The invention of the telescope, the discovery of the “laws of motion” and gravity in the 17th century prompted the

The scope of Natural Sciences is to create principles, theories and laws about the natural world. Natural Sciences theories and laws are based on a scientific methodology (hypothetico-deductive method ). The scientific method always tries to connect theory and observation, this is one manner to consistently organize our observation of the natural world . Experiments are often used in order to replicate aspects of the world in which we are interested. In fact, following this method before stating something to be true scientists needs first to arrange an hypothesis then make some tests in order to prove the theory and finally make up the law. Doing that we can say to acquire a proof and, therefore, good knowledge.
